Alpina B3 GT3 based on the BMW 3-Series Coupe
Limited to just 99 cars, the B3 GT3 seeks to blend elements of the championship-winning B6 GT3 race car with design elements familiar to Alpina customers worldwide.
Under the hood, Alpina has extracted 408 horsepower from BMW’s 3.0-liter, twin-turbo six-cylinder engine. A lightweight titanium exhaust system reduces mass while helping to boost horsepower and add just the right exhaust note.
Alpina also adds a fully-adjustable coilover suspension for maximum performance on track and comfort on the road. Springs and stabilizer bars, meanwhile, have been specially chosen for optimum handling, and front camber is easily adjustable for track-day set ups.
Alpina’s iconic turbine wheels are 19-inch, forged for strength and light weight. For customers desiring the maximum track-day performance, a set of GT3 Cup wheels and tires (Michelin Pilot Sport Cup+) are an available option.
Since the Alpina B3 GT3 can sprint from 0-60 mph in 4.6 seconds and features a top speed of 186 mph, brakes are also upgraded for additional performance. The fixed caliper, racing-style setup uses six-piston calipers and 15-inch rotors up front, with four-piston calipers and 14-inch rotors in the rear.
The B3 GT3 gets aerodynamic enhancements, such as a carbon-fiber front splitter, a rear diffuser and a carbon-fiber rear wing. Alpina claims that the changes cancel lift, and that the B3 GT3 is the first road-going Alpina to actually generate downforce at speed.
The B3 GT3 will be available in Black, White, Alpina Blue metallic or wrapped in green vinyl to match the B6 GT3 race car. Prices haven’t been set, but expect the B3 GT3 to carry a hefty premium over even BMW’s M3 Coupe; still, we're sure it will be substantially less expensive than Alpina's B6 Biturbo Coupe. The cars will be delivered by Alpina dealers beginning in the spring of 2012.
