A limited edition with motor sport genes based on the BMW ALPINA B3 S Bi-Turbo Coupé

ALPINA's recent return to international motor sport peaked this year, with the drivers Alexandros Margaritis and Dino Lunardi winning the German GT Serial, the 2011 ADAC GT Masters Championship, in the BMW ALPINA B6 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 BMW ALPINA B3 GT3 combines exceptional characteristics and technical features of the ALPINA B6 GT3 race car with archetype design elements of iconic ALPINA automobiles of the past – to the delight of ALPINA customers and enthusiasts worldwide.

BMW Alpina B3 GT3 655x450

Strictly limited to 99 cars, the BMW ALPINA B3 GT3 will exist available from bound 2012.

POWERTRAIN

The exceptionally polish twin turbocharged iii.0liter in line half dozen-cylinder engine from the BMW ALPINA B3 Due south Bi-Turbo – with its massive torque and effortless functioning – is besides employed in the B3 GT3. By alteration the exhaust organisation and replacing the rear silencer the back pressure level has been farther reduced, increasing output in the B3 GT3 by 8hp. The direct petrol injected engine now delivers a full power output of 408hp at 6000rpm and 540Nm of torque at 4500rpm.

High performance fixed calliper brake arrangement
Also exceptional acceleration, in 4.6s from 0-100km/h, and a fulminant ability delivery, negative acceleration also plays a pivotal office in satisfying the demands of enthusiast drivers. The B3 GT3 features a high performance motor sport brake set-up with 6-piston stock-still callipers at the front and 4-piston fixed calliper at the rear, with discs measuring 380 x 35 mm at the forepart and 355 x 32 mm at the rear. The brake callipers are painted in blue with discrete ALPINA writing in silver.
Overall, the brakes are designed for high stress and load under forced weather condition and are characterised by excellent fading resistance, good modulation (control) and response – without sacrificing comfort and practicality.

Titanium rear silencer and tailpipes, lightweight made by Akrapovič
Developed in collaboration with Akrapovič, the renowned specialist for Titanium exhaust systems, the B3 GT3 exhaust arrangement is lightweight, impressive notwithstanding elegant in advent and, in keeping with the graphic symbol of the car, has a raspy sound.
The use of Titanium for the rear silencer and tailpipes, in addition to other constructional pattern measures such every bit the removal of the middle silencer, the use of an x-section and significantly larger diameter pipes, has resulted not merely in a reduction in dorsum pressure but also a weight saving of 11kg.Taking design cues from the B6 GT3 race machine and in order to back up weight reduction efforts, the exhaust organisation 'merely' has ii typically ALPINA oval shaped tailpipes but of increased diameter (115mm). In add-on to its heat protective function, the lightweight carbon tailpipe trim provides for a more aggressive blueprint. All-encompassing sound development measures where aimed at achieving a natural, unfiltered and typical six cylinder sound.

CHASSIS & SUSPENSION

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 dissimilar set-ups. The direct transfer of this applied science '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 co-ordinate to personal preference.

The coilovers are fully meridian adjustable, meaning the ride height of the vehicle tin can exist changed significantly. Additionally the dampers characteristic 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-upwards for normal driving while simultaneously offer an aamplitude of adjustment for too achieving a purely track-focussed race fix-upwards.

Primal suspension components including the springs and stabilisers have been specifically calibrated past ALPINA to suit the dynamic focus of the B3 GT3. Special top mounts with adjustable top mount plates at the front ensure an particularly potent connectedness to the chassis. Combined, all these components ensure that the B3 GT3 exhibits the kind of poised and extremely neutral treatment which one expects from ALPINA.
The overall chassis and suspension set-up translates into a real performance increment and infrequent levels of lateral grip. If necessary over and understeer can as well be influenced according to personal preference by means of adjusting the camber at the front, just like on the B6 GT3 race car.

ALPINA GT3 Archetype 19" lightweight blend wheels, forged
Anyone mentions the name ALPINA, well-nigh people inevitably recollect of the famous ALPINA CLASSIC calorie-free alloy wheels, their closely guarded trademark pattern significantly shaping the advent of almost all BMW ALPINA automobiles since the first.

It is merely logical and so, that the new and exclusively for the B3 GT3 available lightweight forged blend wheels as well bear the Classic design. Forged aluminium alloy exhibits much higher stiffness and force characteristics compared to conventional bandage aluminium alloy, translating into a significant weight reduction and more pattern freedom. The pattern 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 especially fine and 'make 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 one-half-an-inch in width to of 8.5 x 19" front end and 9.5 ten 19" rear (front end: 8.6kg, rear: 9.5kg).

GT3 Cup wheel and tyre set up
For everyday use, the B3 GT3 comes equipped with MICHELIN Pilot Sport 2 tyres as standard. For the race rails, an optional GT3 Cup wheel and tyre fix, 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 first-class performance on the track in dry out conditions and at an optimum tyre operating temperature range from l°C to xc °C. Despite being route legal, these tyres are not recommended for everyday use because public roads practice non offer the suitable conditions for achieving the optimum tyre operating temperatures. Furthermore, these tyres have very piffling negative profile, necessitating super careful driving in damp and moisture road weather (aquaplaning).

DESIGN

DESIGN EXTERIOR – Sophisticated aerodynamics
Besides its competitive drivetrain and suspension technology, the B6 GT3 race motorcar managed to more hold its own in the ADAC GT Masters thanks to its exceptional aerodynamics – downforce playing a vital function in achieving fast lap times. The B3 GT3 special edition exhibits a number of aerodynamic features which take 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 end valence, ensures excellent aerodynamic properties at the front end stop. To attain an platonic aerodynamic rest 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 office in ensuring that the aerodynamic efficiency at the rear cease is improved.
In summary, the optimum blueprint and combination of these components ways that lift has been completely dialled out, the B3 GT3 is the first roadgoing BMW ALPINA automobile to showroom bodily downforce at the front end and rear.

Interior, tradition meets Sport
All B3 GT3'south characteristic a Leather/Alcantara interior upholstery in black, both commuter and passenger are seated in lightweight Recaro sport seats with seat heating. Ergonomically shaped and with a firm seat absorber, 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, manus finished with Blue/Green stitching.
