BMW tuner par excellence Alpina is returning to the motor racing scene for the first time in two decades with the new B6 GT3, which the pseudo-works firm unveiled for the first time here at the Geneva Motor Show. Based on the 6 Series, the B6 GT3 features a unique radial supercharger fitted to its 4.4-liter V8 to drive 530 horsepower to the rear wheels – in proper Bavarian style – in what looks to be a compelling competition package. Alpina itself will be fielding a pair in the European FIA GT3 series and at "selected 24-hour endurance races" (Nurburgring, Le Mans... we're looking at you), but the B6 GT3 will also be offered to private teams. Alpina has fitted adjustable everything to the car and a full array of electronic control systems to ensure that gentlemen racers – not just professional drivers – will be able to handle it and so that the car will qualify for a wide array of racing series
