Using the same twin-turbo 3.0 liter inline six-cylinder unit from the Alpina B3 S Bi-Turbo,  the B3 GT3 gets a modified exhaust system and a new rear silencer that  boosts output by 8 PS (6 kW / 8 hp) over the standard engine with  maximum power now rated at 408 PS (300 kW / 402 hp) and 540 Nm (398  lb-ft) of torque. The B3 GT3 also features a titanium rear silencer with  double 115 mm tailpipes from Akrapovic. The 0 to 100 km/h (62 mph) sprint takes 4.6 seconds. Wheels are the Alpina GT3 CLASSIC 19-inch lightweight alloy wheels  with Michelin Pilot Sport 2 tires for the road or Michelin Pilot Sport  Cup+ tires for the track. The B3 GT3 also comes with a race-bred  coilover sport suspension. For the front end aerodynamics is a carbon fiber front splitter  mounted under the front spoiler and dive plates mounted on the side of  the front valence. At the rear is a diffuser and a carbon wing. Inside is a black finish in leather and Alcantara and Recaro sports seats. The B3 GT3 will be a limited-edition model with only 99 units being  made available. The green/blue/silver livery (full-body vinyl wrap) from  the official B6 GT3 racer with a complementary interior trim in green  lacquer will be offered as optional. The B3 GT3 goes on sale in the spring of 2012 with prices set at approximately €90,000, including 19% VAT in Germany.
Press release:
 
 Alpina BMW B3 GT3
 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.
 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.
 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).
 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.
 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.
 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.
 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.
 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.
 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 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.
