New BMW Alpina B3 Bi-Turbo Racing to the Geneva Auto Salon

Posted by Alex Bale Friday, February 15, 2013

BMW has a very close relationship with Alpina, even offering the latter's special models through its own dealers and with full warranty. At least for now, the only Alpina model available through official channels in North America is the 7-Series-based B7 flagship, even though the German specialty brand has its own proposal for most BMW models.

At the Geneva Auto Salon in March, Alpina will welcome another member in its family, the next generation of the B3 Bi-Turbo, based on the F30 3-Series sedan.

Alpina itself released only a single, partially blocked-out picture of the new B3 Bi-Turbo without any details, but the crew from the BMWBlog got their hands on a full blown image and preliminary specifications.

According to the report, the new B3 Bi-Turbo will use an upgraded version of the 335i's 3.0-liter turbocharged inline-six engine producing 404hp (410PS), linked to an eight-speed automatic transmission driving the rear wheels, for a 0-100km/h run in just 4.0 seconds. The car is said to return a combined fuel economy of 7.9lt/100km (29.8mpg US / 35.8mpg UK).

2012 Alpina BMW B6 Bi-Turbo Convertible

Posted by Alex Bale

High-performance convertibles are automobiles for real connoisseurs. They combine characteristics whose sole purpose is to give driver and passengers maximum pleasure. In doing so they combine the best qualities of their related species, so that they may be experienced even more directly and tangibly with the top down. The beguiling performance, powerful drive and fantastic sound of super sports cars. The elegance, dynamics and attractive lines of grand coupés. The luxury, comfort and cruising ability of refined luxury sedans. Generally speaking, qualities that have long characterised ALPINA automobiles. It therefore comes as no surprise to learn that the new ALPINA BMW B6 Bi-Turbo Convertible offers a special experience for all the senses.

Alpina BMW B6 Bi-Turbo Convertible

DRIVE - First class performance and economy

The all-aluminium V8 power plant produces 507hp (373kW) at a moderate 5500rpm, with a maximum torque of 700Nm between 3000rpm - 4750rpm. Two turbo-chargers configured in parallel, each feeding one of the two cylinder banks, with specially developed large diameter exhaust-turbines allow this engine configuration to provide both exceptional power output and an abundance of torque over an especially broad rpm range while maintaining excellent throttle response at low rpm.

Alpina BMW B6 Bi-Turbo Convertible

The comprehensive high-performance cooling system comprises an indirect inter-cooling system (air-to-water/water-to-air) with short intake tracts and increased inter-cooler flow. The systems excellent thermodynamic efficiency is guaranteed by a large-volume low-temperature inter-cooler radiator, as well as two water-toair inter-coolers placed close to the engine. High-performance MAHLE pistons are designed specifically to deal with temperatures and pressures associated with up to 1.0 bar charging and the engine's 9.2:1 nominal compression ratio. Altogether this results in an impressive specific output of 115.3 horsepower (85kW) per litre and a mean total compression of 20.1 bar.

Alpina BMW B6 Bi-Turbo Convertible

Direct injection and Double-VANOS contribute to the B6 Bi-Turbo's class-leading consumption and emission figures: 10.9l/100km (25.9mpg) and 255g/km CO2 (Combined, measured according to ECE Norm).

TRANSMISSION - Eight-Speed All-Rounder

Adapted and tested in co-operation with ZF, the advanced SWITCH-TRONIC 8-speed Sport Automatic Transmission sets benchmarks. With ALPINA's philosophy the guiding credo, engineers have spent thousands of development and test hours ensuring that no other performance automatic transmission comes close to providing this level of both comfort and performance.

Alpina BMW B6 Bi-Turbo Convertible

Using the Sport (S) Shift Mode a completely different character emerges: the transmission is crisp and unmistakably immediate. The innovative single-cylinder fadeout (known as 'Einzelzylinderausblendung' in German) enables super quick up-shifts which take just milliseconds. Depending on the load on the transmission, the injection of fuel into a given cylinder is interrupted for a fraction of a second, creating the required reduction in torque that the automatic transmission needs for the up-shift. The advantages versus the typical method of timing retardation are noticeably quicker shifts, improved thermo-dynamic efficiency due to reduced exhaust temperatures and lower fuel consumption. Each up-shift is accompanied by a deep back-pressure burble.

Alpina BMW B6 Bi-Turbo Convertible

The SWITCH-TRONIC buttons, for use in the Manual (M) Shift Mode, are ergonomically and unobstrusively positioned on the back of the steering wheel, and allow the driver to take complete control of the transmission. The system allows for multi-simultaneous down-shifts in milliseconds, hereby the transmission will skip several gears depending on engine loads and rpm. In this manner the 8-speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC reveals itself as extremely multi-faceted, providing the right shift characteristic for any and all situations.

The Automatic Up-Shift function means that the transmission will up-shift into a higher gear once a certain rpm threshold has been passed in the current gear. In certain driving situations this may not be desired, for example during especially sporty driving or for example when encountering multiple tight hair-pin corners. The simultaneous selection of either Sport, Sport+ or DSC OFF Mode using the Drive Dynamic Control button and the selection of the M Shift Mode (transmission) will deactivate the automatic up-shift funtion. The transmission will hold the selected gear up to maximum rpm's (electronically limited) and will not automatically up-shift into a higher gear.

The intelligent coupling of state-of-the-art engine and transmission technologies give the ALPINA BMW B6 Bi-Turbo Convertible stunning performance figures: 0-100km/h in 4.8s, and a top speed of 311km/h.

EXHAUST SYSTEM - Pure-bred, Sonorous, Lightweight

Special consideration was given to the development of the exhaust system in the ALPINA BMW B6 Bi-Turbo Convertible. A person's sense of hearing is particularly heightened when driving with the top down and almost craves for a fantastic sound experience. For the first time, ALPINA has collaborated with Akrapovic on the development of a lightweight exhaust system made from high-strength titanium. Faithful to the guiding principle of 'form follows function', the entire system is noted not only for its acoustics and appearance, but also for its technical refinements. In addition to a weight-saving of 50% compared to the conventional use of stainless steel, the exhaust system also boasts impressive technical details. The engineers from ALPINA and Akrapovic have achieved quite a feat, managing to retain a diameter of 2 x 70mm throughout the entire length of the exhaust system, despite the tricky 'packaging'. In conjunction with further design refinements, exhaust back-pressure is reduced to an absolute minimum.

In interaction with the powerful engine, the exhaust system generates a backdrop of deep, sonorous eight-cylinder sound - powerful, sporty, but never obtrusive, due to intelligent, controllable exhaust valves. These offer the driver a special degree of influence over the sound experience, and can be controlled using the Drive Performance Control. In Comfort+ and Comfort Mode the valves are closed, opening at 3000rpm, regardless of the selected gear. In 1st and 2nd gear decisive use of the accelerator will cause the valves to open (at approx. 60% load) and the B6 Bi-Turbo to elicit a special symphony from the tailpipes during dynamic bursts of acceleration. As befits the character of the B6 Bi-Turbo in Sport and Sport+ Modes, the exhaust valves remain open at all times.

CHASSIS - Dynamic Comfort

High-performance convertibles place special demands on their chassis - requiring distinct levels of comfort for easy cruising, safe and neutral handling at top speed, and light-footed agility for the moments in between. In order to do justice to this broad spectrum of requirements, the new ALPINA BMW B6 Bi-Turbo Convertible features the latest electronic suspension technologies and comes with Drive Performance Control (electronically adjustable dampers) and Dynamic Drive (active roll stabilisation) as standard.

This system has been artfully calibrated by ALPINA and is tied into other system parameters controlling steering assistance, torque cushioning and the Dynamic Stability Control system. Featuring pronounced Comfort+, Comfort, Sport and Sport+ modes, the B6 Bi-Turbo transitions effortlessly from cultivated luxury convertible to thorough-bred sports car. Specific springs, increased front wheel camber and a subtle adjustment of the toe-in in conjunction with a 20" wheel-tyre combination all serve to produce a very agile chassis set-up. The lightweight 20" ALPINA CLASSIC wheels, with MICHELIN PILOT SUPER SPORT tyres in the dimensions 255/35 ZR20 front and 285/30 ZR20 rear, contribute significantly to the direct handling and precise steering. Conventional tyres are used to promote ride comfort.

DESIGN EXTERIOR - Exciting Details, Functional Aerodynamics

The BMW 6 Series is marked by an elegant and dynamic design as well as excellent aerodynamic properties. ALPINA gives the new B6 Bi-Turbo a unique, powerful appearance which elegantly underlines the sporty character of this beautiful convertible.

The exterior components that influence the aerodynamic properties of the B6 Bi-Turbo are not just there for aesthetic reasons - their design is subject primarily to functional premises and plays a considerable role in achieving both the top speed and in reducing fuel consumption. Take for example the front spoiler with the integrated carbon fibre front splitter. It causes more air to flow over and around the vehicle, simultaneously reducing the air masses which flow underneath by more than 10%. This leads to a noticeable stabilisation of the front-end at high speeds and plays a role in reducing any tendencies to understeer. The front spoiler, in conjunction with the rear spoiler, ensures that the B6 Bi-Turbo is very well 'tethered' overall. Uplift on the front axle is reduced by 14% and tends towards a value of zero on the rear axle from a speed of 150 km/h.

In addition to an improvement in the CX values, these components also ensure the effective flow of air to various cooler groups, such as the inter-coolers and engine cooling system. One special detail: the high-performance brakes, with a diameter of 374mm front and 345mm rear, are additionally supplied with cooling air by a specially constructed NACA air intake on the front underbody.

The double tailpipes, with a slightly elliptical shape in typical ALPINA style, are designed in titanium and carry small logos that make discreet reference to the origins of the ALPINA exhaust system made by Akrapovic. The rear valence, which attractively and elegantly frames the outlet of the tailpipes, additionally integrates the features of a diffuser.

INTERIOR & EQUIPMENT - Master Craftsmanship, Exclusive Personalisation

Blue ALPINA instruments with high resolution information display with black panel LCD technology. A sport steering wheel, hand-stitched in LAVALINA leather. Blue illuminated entry sills with logo. Or the classic ALPINA exotic wood equipment in myrtle - an exclusive burl wood of the laurel family, which grows only on the Pacific coast of the USA. These are just some of the elegant features of the interior that point to the exclusive origins of the B6 Bi-Turbo Cabrio - just for connoisseurs.

Naturally, no limits are set on the personal predilections of customers. From the paintwork to the interior trims to the colour of the upholstery - everything offered by the extensive BMW and ALPINA equipment range is available. Seldom does a BMW ALPINA leave Buchloe without making use of the virtually limitless personalisation options offered by the ALPINA Manufaktur. Our philosophy dictates that the customer can design his or her own individual interior - made by skilled craftsmen in our leather workshop.

The ALPINA BMW B6 Bi-Turbo Convertible features an extensive range of standard equipment, including leather upholstery, fully adjustable comfort seats with heating system, navigation system with preparation for Bluetooth mobile phone, USB audio interface, Xenon lights and LED fog lights.

2012 Alpina BMW B3 GT3

Posted by Alex Bale

Alpina's recent return to international motor sport peaked this year, with the drivers Alexandros Margaritis and Dino Lunardi winning the German GT Series, the 2011 ADAC GT Masters Championship, in the Alpina BMW B6 GT3.

Alpina BMW B3 GT3

With this achievement Alpina purposefully demonstrates that despite a long absence from motor sports, cutting edge automotive know-how and technical expertise continues to be the foundation for the development of exclusive BMW Alpina automobiles.

Ideal circumstances to re-kindle the long-standing Alpina tradition of creating ultra small series limited editions.

The Alpina BMW B3 GT3 combines exceptional characteristics and technical features of the Alpina BMW B6 GT3 race car with classic design elements of iconic Alpina automobiles of the past - to the delight of Alpina customers and enthusiasts worldwide.

Alpina BMW B3 GT3

Strictly limited to 99 cars, the Alpina BMW B3 GT3 will be available from spring 2012 at a price of approx. € 90.000,- including 19% VAT (German specification, ex-works Buchloe).

Alpina BMW B3 GT3

The exceptionally smooth twin turbocharged 3.0liter in line six-cylinder engine from the Alpina B3 S Bi-Turbo - with its massive torque and effortless performance - is also employed in the B3 GT3. By amending the exhaust system and replacing the rear silencer the back pressure has been further reduced, increasing output in the B3 GT3 by 8hp. The direct petrol injected engine now delivers a total power output of 408hp at 6000rpm and 540Nm of torque at 4500rpm.

Alpina BMW B3 GT3

Titanium rear silencer and tailpipes, lightweight made by Akrapovic

Developed in collaboration with Akrapovic, the renowned specialist for Titanium exhaust systems, the B3 GT3 exhaust system is lightweight, impressive yet elegant in appearance and, in keeping with the character of the car, has a raspy sound. The use of Titanium for the rear silencer and tailpipes, in addition to other constructional design measures such as the removal of the middle silencer, the use of an x-section and significantly larger diameter pipes, has resulted not only in a reduction in back pressure but also a weight saving of 11kg.

Alpina BMW B3 GT3

Taking design cues from the B6 GT3 race car and in order to support weight reduction efforts, the exhaust system 'only' has two typically Alpina oval shaped tailpipes but of increased diameter (115mm). In addition to its heat protective function, the lightweight carbon tailpipe trim provides for a more aggressive design. Extensive sound development measures where aimed at achieving a natural, unfiltered and typical six cylinder sound.

Alpina BMW B3 GT3

High performance fixed calliper brake system

Besides exceptional acceleration, in 4.6s from 0-100km/h, and a fulminant power delivery, negative acceleration also plays a pivotal role in satisfying the demands of enthusiast drivers.

Alpina BMW B3 GT3

The B3 GT3 features a high performance motor sport brake set-up with 6-piston fixed callipers at the front and 4-piston fixed calliper at the rear, with discs measuring 380 x 35 mm at the front and 355 x 32 mm at the rear. The brake callipers are painted in blue with discrete Alpina writing in silver.

Alpina BMW B3 GT3

Overall, the brakes are designed for high stress and load under forced conditions and are characterised by excellent fading resistance, good modulation (control) and response - without sacrificing comfort and practicality.

Alpina BMW B3 GT3

Alpina GT3 CLASSIC 19" lightweight alloy wheels, forged

Anyone mentions the name Alpina, most people inevitably think of the famous Alpina CLASSIC light alloy wheels, their closely guarded trademark design significantly shaping the appearance of almost all BMW Alpina automobiles since the beginning. It is only logical then, that the new and exclusively for the B3 GT3 available lightweight forged alloy wheels also carry the CLASSIC design. Forged aluminium alloy exhibits much higher stiffness and strength characteristics compared to conventional cast aluminium alloy, translating into a significant weight reduction and more design freedom. The design of the 19" lightweight forged alloy wheels, which are painted in Himalaya Grey, has been inspired by the B6 GT3 race car. The 20 spokes are particularly fine and 'clean', giving the wheel a minimalist technical and timeless appearance. The new wheels, which are 25% lighter, result in a further weight reduction of 10kg, despite increasing half-an-inch in width to of 8.5 x 19" front and 9.5 x 19" rear (front: 8.6kg, rear: 9.5kg).

Race-bred coilover sports suspension, perfectly balanced

The coilover suspension technology in the B6 GT3 played a central role in achieving success at widely varying race circuits, which all required very different set-ups.

The direct transfer of this technology 'from the track to the street' allows for far reaching adjustment of the suspension on the B3 GT3 according to widely different requirements, and for fine-tuning and balancing the handling according to personal preference. The coilovers are fully height adjustable, meaning the ride height of the vehicle can be changed significantly. Additionally the dampers feature a 12-fold compression and 18-fold rebound adjustment. The range of adjustment has been carefully calibrated to allow for a dynamic yet sufficiently comfortable road-biased set-up for normal driving while simultaneously offering an amplitude of adjustment for also achieving a purely track-focussed race set-up.

Fundamental suspension components including the springs and stabilisers have been specifically calibrated by Alpina to suit the dynamic focus of the B3 GT3. Special top mounts with adjustable top mount plates at the front ensure an especially stiff connection to the chassis. Combined, all these components ensure that the B3 GT3 exhibits the kind of poised and extremely neutral handling which one expects from Alpina.

The overall chassis and suspension set-up translates into a real performance increase and exceptional levels of lateral grip. If necessary over and understeer can also be influenced according to personal preference by means of adjusting the camber at the front, just like on the B6 GT3 race car.

Sophisticated aerodynamics

Besides its competitive drivetrain and suspension technology, the B6 GT3 race car managed to more than hold its own in the ADAC GT Masters thanks to its exceptional aerodynamics - downforce playing a vital role in achieving fast lap times. The B3 GT3 special edition exhibits a number of aerodynamic features which have been directly derived from the experience gained in motor racing.

The combination of a carbon front splitter, which is mounted on the underside of the front spoiler, and dive plates, which are mounted on the side of the front valence, ensures excellent aerodynamic properties at the front end. To achieve an ideal aerodynamic balance a carbon wing is mounted at the rear. The profile of the rear wing is such, that it reduces lift at the rear significantly without negatively effecting the drag coefficient. The rear diffusor, in black matt, also plays a part in ensuring that the aerodynamic efficiency at the rear end is improved.

In summary, the optimum design and combination of these components means that lift has been completely dialled out, the B3 GT3 is the first roadgoing BMW Alpina automobile to exhibit actual downforce at the front and rear.

GT3 Cup wheel and tyre set

For everyday use, the B3 GT3 comes equipped with MICHELIN Pilot Sport 2 tyres as standard. For the race track, an optional GT3 Cup wheel and tyre set, consisting of a set of Alpina GT3 CLASSIC 19" lightweight alloy wheels, forged, with MICHELIN Pilot Sport Cup+ tyres is available. The Cup tyres deliver excellent performance on the track in dry conditions and at an optimum tyre operating temperature range from 50°C to 90 °C. Despite being road legal, these tyres are not recommended for everyday use because public roads do not offer the suitable conditions for achieving the optimum tyre operating temperatures. Furthermore, these tyres have very little negative profile, necessitating super careful driving in damp and wet road conditions (aquaplaning).

Interior, tradition meets Sport

All B3 GT3's feature a Leather/Alcantara interior upholstery in black, both driver and passenger are seated in lightweight Recaro sport seats with seat heating. Ergonomically shaped and with a firm seat cushion, they deliver excellent comfort in combination with optimum lateral support. The seats can be adjusted in height by about 30mm via their mounting points and feature manual back and horizontal adjustment.

A special highlight for Alpina enthusiasts: vertical stripes designed in Alpina racing colours are integrated into the front and rear seats. The sports steering wheel with paddles is finished in grippy Alcantara, hand finished with Blue/Green stitching.

Limited 99

Limited to 99 units worldwide, the B3 GT3 features a comprehensive and carefully selected standard equipment level, in line with its sporting character.

For customers wishing to have a built-in navigation system, B3 GT3 is available with an optional Comfort Package, which includes BMW Professional Multimedia Navigation System and BMW Park Distance Control (PDC). Other BMW options are not available. The B3 GT3 is available as standard in Black Sapphire metallic and Mineral White metallic or optionally in special paintwork Alpina Blue matt metallic. The interior trim is carried out in Alcantara black with Alpina writing (embossed).

Unique and exclusive, the B3 GT3 is optionally available with a full body vinyl wrap in the official B6 GT3 race car design (green/blue/silver), including interior trim in green lacquer. All cars are equipped with a rear axle with a Drexler limited slip differential, similar to the B6 GT3 race car. Every B3 GT3 is labelled with a specially designed production plaque in the interior.

2011 Alpina BMW B5 Bi-Turbo Touring

Posted by Alex Bale

ALPINA automobiles are defined by their finely balanced mix of driving dynamics, comfort and everyday luxury. Add to that exceptional functionality and the result is the new BMW ALPINA B5 Bi-Turbo Touring - the quickest of its kind!

The Touring smartly combines the exclusive sophistication of the Saloon with pronounced functionality and versatility. Make no mistake, the Touring offers up to 1670 litres of storage space and an ingenious luggage compartment concept, despite its luxury high performance genes.

Alpina BMW B5 Bi-Turbo Touring

A finely honed suspension and chassis configuration combined with variable dampers makes for an exemplary ride comfort while simultaneously providing sharp handling and excellent high-speed stability.

Alpina BMW B5 Bi-Turbo Touring

The V8 Bi-Turbo accelerates the Touring from 0-62mph in 4.8s while 700Nm of torque paired with the exceptional 8-speed Sport Automatic Transmission with SWITCH-TRONIC means power is always readily available. Modern, dynamic and well toned in appearance - the ALPINA B5 Bi-Turbo Touring has all the right visual qualities to make it the perfect companion for business and leisure.

THE POWERTRAIN - First Class Performance And Economy

The all-aluminium V8 powerplant produces 507 horsepower (373 kW) at a moderate 5,500rpm, with maximum torque of 700Nm from 3,000 to 4,750rpm. „Bi-Turbo" refers to two turbo-chargers configured in parallel, each feeding one of the two cylinder banks. Specially developed large diameter exhaust-turbines allow this engine configuration to provide both exceptional power output and an abundance of torque over an especially broad rpm range while maintaining excellent throttle response at low rpm.

Alpina BMW B5 Bi-Turbo Touring

The comprehensive high-performance cooling system comprises an indirect inter-cooling system (air-to-water/water-to-air) with short intake tracts and increased inter-cooler flow. The systems excellent thermodynamic efficiency is guaranteed by a large-volume low-temperature inter-cooler radiator, as well as two water-to-air inter-coolers placed close to the engine. High-performance MAHLE pistons are designed specifically to deal with temperatures and pressures associated with up to 1.0 bar charging and the engine's 9.2:1 nominal compression ratio. Altogether this results in an impressive specific output of 115.3 horsepower (85kW) per litre and a mean total compression of 20.1 bar.

Alpina BMW B5 Bi-Turbo Touring

Direct injection and Double-VANOS contribute to the ALPINA B5 Bi-Turbo's class-leading performance, emissions and economy in this segment: 10.8l/100km / 26.2mpg (Touring: 10.9l/100km / 25.9mpg) and 252g/km (Touring: 255g/km) CO2 (Combined, measured according to ECE Norm).

TRANSMISSION - Eight-Speed All-Rounder

Adapted and tested in co-operation with ZF, the advanced SWITCH-TRONIC 8-speed Sport Automatic Transmission sets a new benchmark. With ALPINA's philosophy the guiding credo, our engineers have spent thousands of development and test hours ensuring that no other performance automatic transmission comes close to providing this level of both comfort and performance.

Using the Sport (S) Shift Mode a completely different character emerges: the transmission is crisp and unmistakably immediate. The innovative single-cylinder fade-out (known as 'Einzelzylinderausblendung' in German), initially engineered for application in the ALPINA B6 GT3 race car, enables super quick up-shifts which take just milliseconds. Depending on the load on the transmission, the injection of fuel into a given cylinder is interrupted for a fraction of a second, creating the required reduction in torque that the automatic transmission needs for the up-shift. The advantages versus the typical method of timing retardation are noticeably quicker shifts, improved thermo-dynamic efficiency due to reduced exhaust temperatures and lower fuel consumption. Each up-shift is accompanied by a deep back-pressure burble.

The intelligent coupling of state-of-the-art engine and transmission technologies give the ALPINA B5 Bi-Turbo stunning performance figures: just 4.7 (Touring: 4.8) seconds from 0-100km/h / 0-62mph are needed, on the way up to a top speed of 307km/h / 191mph (Touring: 303km/h / 188mph). Massive braking capability in the form of ventilated high-performance brakes (front: 374mm/14.7in, rear 345mm/14.6in) ensures braking on par with pure-bred sports cars.

SUSPENSION - Dynamic Comfort

The times when „properly stiff" suspensions were seen as a positive handling characteristic are long gone. It remains a fact that a truly neutral set-up, even at the limit, provides the best technical compromise. This is achieved in part through shorter ALPINA springs and specific transverse suspension arms which in combination result in an optimised camber.

Together with 20" wheels and tyres this yields a very balanced and direct chassis set-up, discarding a pure sport-orientated approach for an agile suspension with precise turn-in. Mounted on the light-weight 20" ALPINA CLASSIC wheels are non-run-flat MICHLIN PILOT SUPER SPORT tyres measuring 255/35 ZR20 front and 285/30 ZR20 rear. Representing the latest in ultra-high performance tyre technology available today, they feature a running surface is made up of 2/3rds soft compound (centre) and 1/3rd hard compound (outside and flanks). This mixture makes for excellent durability despite typical hard use in high-performance vehicles yet provides very good grip in the wet. Enhanced tread stability and a new flank reinforcement technology ensures the tyre is less likely to suffer from spikes in temperature with a resulting loss of grip in the dry.

To fulfil the seemingly contradictory demands for comfort, everyday usability and sports car like handling, the ALPINA B5 Bi-Turbo is equipped with electronically-adjustable dampers (Dynamic Damper Control and Drive Dynamic Control). This system has been artfully calibrated by ALPINA, and is tied into other system parameters controlling steering assistance, torque cushioning and the Dynamic Stability Control system. Featuring pronounced Comfort, Normal, Sport and Sport+ modes, the ALPINA B5 Bi-Turbo transitions effortlessly from cultivated luxury to thorough-bred sportiness. Light steering, ultra-comfortable suspension and an imperceptibly shifting transmission make the ALPINA B5 Bi-Turbo an ideal partner in stop-and-go traffic, when covering great distances or when encountering less than perfect road surfaces. Yet at the touch of a button, the ALPINA B5 Bi-Turbo will track through tricky corners and exciting sections of road with an agility and light-footedness like no other in its class.

An especially for the BMW ALPINA B5 Bi-Turbo in co-operation between ALPINA and Drexler Motorsport adapted limited-slip differential is available as an option. This mechanical limited-slip differential improves traction during dynamic driving and minimises slip by distributing torque and power to the wheel with the most grip. The operation of the limited-slip differential is permanent and independent from other driving dynamic settings or systems. Significant characteristics include: torque sensing multidisc differential with pre-tensioning; active locking characteristic up to 30 % under load and 20 % under trailing throttle; very reactive in sensing slip, harmonious self-steering properties and excellent directional stability; motor sport quality, forged gears, CNC milled housing, hand built.

DESIGN & INTERIOR - Classic Craftsmanship Meets Modern Technology

The ALPINA B5 Bi-Turbo presents typical ALPINA virtues and design cues in a new and convincing fashion, with a refreshing and dynamic appearance. Both the saloon's and the touring's silhouette begins with an attention commanding front that is powerful and confident, and ends with a harmonious and elegant rear. The ALPINA trademark two double-ended-pipes are artfully integrated into the rear valence which features a discreet diffuser. The diffuser can be deleted as needed, should the customer desire the optional ability to tow a trailer. In combination with the rear spoiler (Saloon), the ALPINA B5 Bi-Turbo's total aerodynamic package yields the highest levels of safety and stability, especially at high speeds. The resulting reduction in lift, speed-dependent, can reach a remarkable -60% front and -30% rear.

The interior reveals the expected discreet touches that suggest the ALPINA B5 Bi-Turbo's exclusive pedigree. The standard equipment level is comprehensive: leather interior, versatile and adjustable Comfort seats, an excellent navigation system with Bluetooth preparation, and Xenon headlamps all ensure the driver's and passengers' well-being. The hand-stitched LAVALINA leather SWITCH-TRONIC steering wheel can be positioned exactly as needed to see the blue ALPINA gauges with black-panel LCD technology, thanks to the electrically-adjustable steering column. The classic ALPINA burled Myrtle wood trim provides a warm ambience - found only on the USA's Pacific Coast it is cultivated from dedicated Laurel tree groves grown for just this purpose. Optional ALPINA Piano Lacquer interior trim with its silver diagonal rhombs, offers a modern and just as exclusive alternative.

The interior's warm ambience and modern treatments foster a sense of well-being. For those who would only award themselves that something unique, exclusive volumes and the ALPINA philosophy of hand-craftsmanship offer a nearly endless spectrum of personalisation.

Five different generations of 5 Series-based Alpina automobiles have been developed in the last 35 years, revealing to those in the know a unique and exclusive driving experience. The sixth generation draws from the finest ingredients provided by those previous generations to create a mouth-watering palette of characteristics for the most discerning of drivers in the high performance luxury saloon segment.

THE POWERTRAIN - First Class In Both Performance And Economy

First introduced in the Alpina BMW B7 Bi-Turbo, the all-aluminium V8 powerplant endows the new B5 Bi-Turbo with sensational pace. It achieves 507 horsepower (373 kW) at a moderate 5,500rpm, with maximum torque of 700Nm from 3,000 to 4,750rpm. The "Bi-Turbo" appellation refers to the two turbochargers comfortably nestled inside the V shaped 8 cylinder block. They work in parallel, each feeding one of the two cylinder banks. Specially developed for Alpina in partnership with Honeywell-Garrett, the bespoke exhaust turbines are generously dimensioned. Compared to its super-charged predecessor, this engine configuration delivers more torque over a broader rev range and improves throttle response at low revs.

To fully leverage the potential of the engine, Alpina have optimised the indirect inter-cooling system (air-to-water / water-to-air) with short intake tracts and increased inter-cooler flow. The high-performance cooling package gains its thermo-dynamic efficiency through the use of a large-volume low-temperature inter-cooler, as well as two water-to-air inter-coolers placed close to the engine. The pistons are a high-performance variant developed together with Mahle to deal with the extreme temperatures and pressures associated with up to 1.0 bar charging and the engine's 9.2:1 nominal compression ratio. Altogether this results in an impressive specific output of 115.3 horsepower (85kW) per litre and a mean total compression of 20.1 bar.

Direct injection and Double-VANOS contribute to the Alpina BMW B5 Bi-Turbo's class-leading performance in terms of emissions and economy in the super saloon segment: 10.8 l/100km (26.2 Imp. mpg) and 252g/km CO2 (Combined as per the ECE Norm).

TRANSMISSION - The Eight-Speed All-Rounder

Adapted and tested in cooperation with ZF, the advanced SWITCH-TRONIC 8-speed sport automatic transmission sets a new benchmark. With Alpina's philosophy the guiding credo, our engineers have spent thousands of development and test hours ensuring that no other performance automatic transmission comes close to providing this level of both comfort and sportiness.

Alpina BMW B5 Bi-Turbo

The blend of eight speeds and plenty of torque makes for unparalleled comfortable gear changes with no noticeable interruption to the delivery of power - only the accompanying acoustics and the dynamic rev counter provide feedback as to the workings of the transmission. The 700Nm of torque means the Alpina BMW B5 Bi-Turbo excels at gliding along at low speeds in a high gear with minimum revs, benefiting both consumption and comfort.

In Sport mode a completely different character emerges: the transmission is crisp and unmistakably immediate. The innovative single-cylinder step-down (EZA), specially developed by Alpina for the B5 Bi-Turbo allows for super quick up-shifts in just milliseconds, in spite of the high torque. Depending on the load on the transmission, the injection of fuel into a given cylinder is interrupted for a fraction of a second, creating the required reduction in torque that the automatic transmission needs for the up-shift. The advantage versus the typical timing retardation are noticeably quicker shifts, and improved thermo-dynamic efficiency due to reduced exhaust temperatures as well as lower fuel consumption. The single-cylinder step-down (EZA) is accompanied by a tone nothing short of spectacular, as each shift harbours a deeply sonorous back-pressure burble.

The Manual mode gives the driver full control over every shift. The SWITCH-TRONIC buttons are ergonomically and aesthetically positioned on the back side of the steering wheel, and can be used by the driver in whatever manner he or she wishes, based on traffic and the roadway at hand. The system also allows for multi-simultaneous down-shifts in fractions of a second, hereby the transmission will skip several gears depending on accelerator loads and revs. In this manner the 8-speed sport automatic transmission with Alpina SWITCH-TRONIC reveals itself to be multi-faceted and able to provide the proper shift characteristic for any and all situations.

The intelligent coupling of state-of-the-art engine and transmission technologies give the Alpina BMW B5 Bi-Turbo strong performance figures: just 4.7 seconds to 62mph (100km/h) are needed, on the way up to a top speed of 191mph (307km/h).
Even if the driver is seldom in such a rush: massive braking capability in the form of ventilated high-performance brakes (front: 374mm/14.7in; rear 370mm/14.6in) ensures braking on par with pure-bred sports cars.

SUSPENSION - Excitingly Sporty, Relaxingly Comfortable

The times when "properly stiff" suspensions were seen as a positive handling characteristic are long gone. It remains a fact that a truly neutral set-up, even at the limit, provides the best technical compromise. This is achieved in part through shorter yet very progressive springs and special suspension arms, which in combination results in more camber on the front track.

Together with 20" wheels and tyres, Alpina have achieved a very balanced and direct chassis set-up, discarding a pure sport-orientated approach for an agile suspension with precise turn-in. The new light-weight 20" Alpina CLASSIC are shod with the most advanced high performance tyre technology available today. Making their debut on the Alpina BMW B5 Bi-Turbo, the new MICHELIN PILOT SUPER SPORT tyres, which measure 255/35ZR20 at the front and 285/30ZR20 at the rear, provide highest levels of high-speed stability. In addition to improved all-round capabilities, these non run-flat tyres provide greater traction on wet roads, offer improved hydro-planing behaviour and excellent rolling comfort.

To fulfil the highest demands in terms of comfort, everyday usability and razor-sharp handling when called for, the B5 Bi-Turbo is equipped with electronicallyadjustable suspension (Variable Damper Control). Using the control switch mounted to the left of the shift lever, the driver can select between Normal, Comfort, Sport and Sport+. This system has been artfully calibrated by Alpina, and is tied into other system parameters controlling steering assistance, torque cushioning and DSC. The B5 Bi-Turbo transitions effortlessly from cultivated luxury to thorough-bred sportiness. Light steering, ultra-comfortable suspension and an imperceptibly shifting transmission Alpina BMW B5 Bi-Turbo the ideal partner in stop-and-go traffic, when covering great distances or when encountering less than perfect road surfaces. Yet at the touch of a button, the B5 Bi-Turbo will track through tricky corners and exciting sections of road with an agility and light-footedness like no other in its class.

When the 8-speed sport automatic's manual mode is combined with the selection of the Sport or Sport+ modes, the driver benefits from a new feature: no mandatory up-shifts. When truly pressing on through twisty sections of road or around hairpins, skilled drivers can remain in their selected gear and not be interrupted by an up-shift.
The optionally available Dynamic Drive reduces body roll in corners, awarding the Alpina BMW B5 Bi-Turbo even more agility.

When placed in Sport+ mode by the driver, the B5 Bi-Turbo's dynamic control systems offer a heightened form of DSC called Dynamic Traction Control (DTC), which allows noticeably more slip at the rear wheels and delays the point at which the traction control systems take over.

DESIGN & INTERIOR - Classic Craftsmanship Meets Modern Technology

The new Alpina B5 Bi-Turbo presents typical Alpina virtues and design cues in a new and convincing fashion, with a refreshing and dynamic appearance.
The self-assured and powerful front commands attention with its decidedly sport-orientated lines and striking air. The rear is especially harmonious, clearly communicating the Alpina BMW B5 Bi-Turbo's family heritage. The Alpina exhaust's two double-ended-pipes are artfully integrated into the rear valance, a discreet rear diffuser completing the silhouette. The diffuser can be deleted as needed, should the customer desire the optional ability to tow a trailer. In combination with the rear spoiler, the B5 Bi-Turbo's total aerodynamic package yields the highest levels of safety and stability, especially at high speeds. The resulting reduction in lift, speed-dependent, can reach a remarkable - 60% front and - 30% rear.

The interior reveals the expected discreet touches that suggest the Alpina BMW B5 Bi-Turbo's exclusive pedigree. The standard equipment level is comprehensive: leather interior, versatile and adjustable Comfort seats, an excellent navigation system with Bluetooth preparation, and Xenon headlamps all ensure the driver's and passengers' well-being. The hand-stitched LAVALINA leather SWITCH-TRONIC steering wheel can be positioned exactly as needed to see the blue Alpina gauges with black-panel LCD technology, thanks to the electrically-adjustable steering column. The classic Alpina burled Myrtle wood trim provides a warm ambience - found only on the USA's Pacific Coast it is cultivated from dedicated Laurel tree groves grown for just this purpose.

THE Alpina BMW B5 BI-TURBO - Brilliantly Balanced High Performance

The overall harmony and the accomplished manner with which the Alpina BMW B5 Bi-Turbo's last fine calibrations were achieved are a common thread, and as always carry that Alpina flair, our signature. Sovereign performance and opulent torque assure excellent performance, this in conjunction with "best-in-class" fuel economy and CO2 emissions. Neutral turn-in and road-holding, agile handling and a many-faceted, adjustable suspension satisfy the highest demands in terms of comfort and a sporting nature. The interior's warm ambience and modern treatments foster a sense of well-being. For those who would only award themselves that something unique, exclusive volumes and the Alpina philosophy of hand-craftsmanship offer a nearly endless spectrum of personalisation.

2010 Alpina BMW B7 Bi-Turbo Allrad

Posted by Alex Bale

With the Alpina BMW B7 Bi-Turbo Allrad, for the first time, Alpina combines its powerful, torque-laden flagship with an optional all-wheel-drive system for even more traction and active safety in every and any driving situation.

Alpina BMW B7 Bi-Turbo Allrad

The Alpina BMW B7 Bi-Turbo Allrad with all-wheel-drive exploits the technical potential of BMW's xDrive System and its intelligent and dynamic distribution of drive power. It continuously and fully variable distributes torque between the front and rear axle within milliseconds.

Alpina BMW B7 Bi-Turbo Allrad

Alpina's unique mapping of the torque distribution markedly enhances driving dynamics and agility, especially when cornering, enabling unexpected levels of sporty handling. In addition to offering maximum available traction under acceleration, the system provides exceptional levels of active safety by constantly monitoring the driving situation and distributing torque accordingly.

Alpina BMW B7 Bi-Turbo Allrad

The all-wheel-drive system is linked to the Alpina BMW B7 Bi-Turbo's many electronic control systems, meaning it can offer an unusually broad spectrum of dynamic driving experiences, just like our demanding customers expect. Unique: in combination with the electronic suspension, consisting of Variable Damper Control and Dynamic Drive (active roll stabilisation), the driver can influence the dynamic torque distribution of the all-wheel-drive system using the Drive Dynamic Control buttons to select between the programs.

Alpina BMW B7 Bi-Turbo Allrad

Comfort / Normal: set-up for maximum safety and comfort, handling is decidedly forgiving and sudden changes in direction will be met by mild understeer.

Sport: facilitates a more assertive driving style with the active role stabilisers programmed to neutral handling with reduced understeer.

Sport+: skilled drivers will particularly enjoy that in this program the torque bias is shifted predominantly to the rear wheels, enabling levels of lateral acceleration and a super-sporty driving style unheard of luxury saloons. In addition, the DSC automatically goes into DTC mode, reducing the intervention of the electronic stability program and allowing more slip at any of the driven wheels.

Regardless of whether Comfort, Normal or Sport is selected, the system recognises lateral acceleration above 0.5 m/s2 as resolute and sport-oriented driving and increases the torque shifted to the rear wheels, without reducing stability.

The instantaneous and fully variable torque distribution remains active regardless of the selected program and constantly delivers the highest levels of traction and active safety in every situation, such as when driving on very mixed road surfaces.

Despite the Alpina BMW B7 Bi-Turbo Allrad's high level of torque, intervention of the DSC stability control system by applying the brakes or by reducing engine output, is only seldom necessary because the intelligent torque distribution is extremely effective at neutralising any indication of under- or oversteer at the onset.

The Alpina BMW B7 Bi-Turbo Allrad tracks in and out of all corners as if on rails - levels of steering lock, lateral acceleration, yaw rates and speed are constantly dictating how much torque needs to be supplied to which axle in order to ensure maximum forward progress.

All of the above takes place instantly and smoothly, the distribution of power going unnoticed by the driver. It makes smooth, fluid sporty driving on winding roads an especially harmonious experience.

2010 Alpina BMW B7 Bi-Turbo

Posted by Alex Bale

With the new Alpina BMW B7 Bi-Turbo, Alpina presents its fourth generation of automobiles based on the BMW 7-Series. Prominent predecessors include the BMW Alpina B12 6.0 and B7, which raised the bar in the high-performance luxury saloon segment. Newly interpreted and in every way state-of-the-art, the Alpina BMW B7 Bi-Turbo unites exclusiveness, athleticism and comfort in perfect harmony.

Alpina BMW B7 Bi-Turbo

Yielding exquisite levels of torque and power from the charged 4.4 litre V8, and in conjunction with the electronically-adjustable suspension with active roll stabilisation, the Alpina BMW B7 Bi-Turbo promises to offer a spectrum of driving experiences so varied as to be unheard of in this class of automobiles. The evolution of the traditional 20-spoke 21" Alpina CLASSIC wheels underline the fresh design language found throughout the Alpina BMW B7 Bi-Turbo and impart it a distinctive appearance and powerful stance.

Alpina BMW B7 Bi-Turbo

POWERTRAIN - FIRST-CLASS IN BOTH PERFORMANCE AND ECONOMY

The Bi-Turbo model designation that now graces this flagship BMW Alpina saloon hints at even more powerful and torque-laden performance over its predecessor, while simultaneously improving upon fuel economy.

Alpina BMW B7 Bi-Turbo

The fully-aluminium, 4395 cm3 V8 aggregate yields 507 peak horsepower (373 kW) at a moderate 5500rpm, with a maximum torque of 700 Nm available between 3000-4750 rpm. Two especially for Alpina powerplant constructed turbochargers, one located above each of the V8's two cylinder banks, are responsible for the forced induction. The turbochargers operate in parallel, with generously-dimensioned turbine vanes measuring 44mm in diameter.

Alpina BMW B7 Bi-Turbo

Thorough exploitation of the engine's potential was achieved by means of optimising the indirect intercooler (air-water/water-air) with its short intake paths and flow-optimised intercooler tracts. All three intercoolers, the low-temperature intercooler integrated into the radiator package, as well as the two engine-near intercoolers are enlarged by approximately 35%, ensuring very high thermo-dynamic efficiency.

Alpina BMW B7 Bi-Turbo

High-performance pistons are at work in the engine, carefully developed to withstand the thermo-dynamic forces created by 9.2:1 compression and a maximum turbo boost of 1.0 bar. The result is a formidable specific output of 115hp (85kW) per litre, with a maximum average compression of 20.1 bar, a benchmark even amongst established sportscars.

Further technical subtleties of this high-tech, EU5-emissions rated powerplant include petrol-direct-injection and Double-VANOS. These contribute in no small measure to the Alpina BMW B7 Bi-Turbo's "Best-in-Class" fuel economy 12.1 l/100km [23.4 Imp. MPG] and a CO2 emissions rating of 282g/km (mixed fuel economy according to ECE norm).

The Alpina BMW B7 Bi-Turbo delivers proof, both in form of its characteristics and its technical data, that high levels of performance and favourable fuel economy are not necessarily a contradiction in terms. Ending in two polished double-tailpipes, the stainless-steel Alpina exhaust system offers up that deep and sonorous yet not intrusive V8 sound that one has come to expect from Alpina.

DRIVETRAIN COMFORT - UNIQUELY SUPERIOR

The Alpina BMW B7 Bi-Turbo is the result of the consistent execution of the Alpina philosophy, in itself the reason why the sharp yet gracious Alpina BMW B7 Bi-Turbo shines so brilliantly in everyday use.

One look at the torque and power diagram is enough to highlight that the Alpina BMW B7 Bi-Turbo will accelerate fiercely yet effortlessly from very low revs. Peak torque is available from an unusually broad range of rpm's, ranging from 3,000 to 4,750 rpm. This wide powerband coupled with the exquisitely geared ZF six-speed automatic sport transmission pampers the occupants with remarkably high levels of smooth drivetrain comfort in every driving situation.

The Alpina SWITCH-TRONIC, which has been programmed to shift exceptionally smooth and comfortable in Automatic mode, offers different shift characteristics for every taste and situation thanks to the additional Sport and Manual modes. Driving the Alpina BMW B7 Bi-Turbo becomes an altogether different experience when using the buttons found on the back of the steering wheel for manually selecting the gears of the automatic transmission. This ensures shifts take place within a few hundred milliseconds and with only minimal interruption to the transmission of power, favourably comparable even to the best twin-clutch transmissions. As a result the Alpina BMW B7 Bi-Turbo sprints from 0-100 km/h in 4.7 seconds, vehemently pressing on to an electronically-limited 280 km/h top speed. Although one rarely finds oneself in need of such haste, the ventilated and generously-proportioned (374 mm dia. front, 370 mm dia rear) high-performance braking system guarantees deceleration values on par with pure-bred sports cars.

THE SUSPENSION - HARMONIOUS, ACCOMPLISHED, IMPRESSIVELY VERSATILE

Long gone are the days when a purely "hard and sporty" ride was a sought-after attribute of suspension set-ups. Striving for truly neutral handling continues to be the intelligent way forward, yielding the best of what is technologically feasible. In pursuit of this goal, marginally shorter and uniquely calibrated springs reduce front and rear ride height by 15mm and 10mm respectively.

Together with the 21" wheel and tyre combination the suspension is at once sensitive to inputs and direct in its feel, yet free from the harshness of a purely sportsoriented suspension, imparting this large saloon with an agility usually only associated with much smaller sports saloons. The light-weight 21" wheels, with their new interpretation of the Alpina CLASSIC wheel design, are shod with an especially selected staggered MICHELIN tyre set-up: 245/35 R21 front and 285/30 R21 rear. Foregoing Run-Flat technology, conventional tyres are used to ensure a supple, comfortable finesse that is rare today.

Alpina have integrated state-of-the-art electronic suspension technologies and skilfully, subtly adjusting them to the demanding requirements of our customers. As part of the Alpina BMW B7 Bi-Turbo standard equipment, the electronic suspension system with Dynamic Damping Control and Dynamic Drive (active roll stabilisation) enable the driver to select from three distinct suspension set-ups: Comfort, Normal and Sport. These are intentionally calibrated to provide noticeably different set-ups, influencing the characteristic of the dampers, the active roll stabilisation as well as the parameters of the power steering assist, throttle response algorithms and load-reversal damping. The Alpina BMW B7 Bi-Turbo offers the driver unheard-of versatility, delivering on long-distance comfort just as readily as on back-road pace, always with a maximum of enjoyment and safety.

Seasoned drivers are not kept from pushing the Alpina BMW B7 Bi-Turbo hard at the limit: the Sport plus mode automatically shifts the traction control systems into Dynamic Traction Control (DTC), an extension of DSC. This allows noticeably more slip at the driven wheels and delayed intervention by the traction control system.

DESIGN & INTERIOR - EVOLUTIONARY STYLING, DOWN TO THE LAST DETAIL

At once dynamic, graceful and potent - the silhouette of the Alpina BMW B7 Bi-Turbo is significantly influenced by the evolutionary new design of the 21" Alpina CLASSIC wheels. A turbine-like three-dimensional curve guides each of the 20 spokes from the centre of the wheel to the rim, at which point they have a milled surface. Depending on the angle of the viewer, the rotational speed of the wheels and the light, the appearance of these classic wheels is constantly changing. Of course they continue to possess the refined tyre air valves, safely and attractively hidden away behind the lockable wheel covers.

In true "form-follows-function" fashion, the typical Alpina front integrates the fresh-air requirements of the transmission and engine oil coolers, which are separated out of the main cooler module for improved efficiency. The design of the front and rear spoiler follows clearly aerodynamically-oriented interests, reducing lift at the front and rear by 30% and 15% respectively. Left and right, the exhaust system's two double tailpipes are seamlessly integrated into the rear valance and are witness to the Alpina BMW B7 Bi-Turbo's potency.

When climbing into the Alpina BMW B7 Bi-Turbo, one immediately takes note of the Alpina door sill trims which are finely illuminated in blue. The SWITCH-TRONIC steering wheel, 385mm in diameter, is gloved and hand-stitched in the finest, most comfortable LAVALINA leather. In the driver's line of sight, red pointers over a field of blue dials grace the instrument cluster, where a Black-Panel LCD screen is responsible for communicating driver-important information. Exclusive interior luxury wood trim in the form of Myrtle Burl, a knotted burl of the Laurel only found on the Pacific Coast of the United States, provides a warm and traditional ambience. Optional Alpina Piano Lacquer interior trim with its silver diagonal rhombs, offers a modern and just as exclusive alternative.

Discreet metal Alpina emblems adorn the upper seatbacks of the standard leather Comfort seats, as much a part of the comprehensive standard equipment as metallic paint or a navigation system with Bluetooth telephone preparation.

Even the engine bay carries a subtle signature by tidily presenting itself with a newly-designed Alpina engine cover.
