German tuner/automaker creates a B3 GT3 with 408 PS (300 kW / 402 hp) and 540 Nm (398 lb-ft) of torque.

Alpina has introduced the BMW Alpina B3 GT3.

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.
