At the 2012 Geneva Motor Show, Alpina, the Buchloe-based company, just took the wraps off their latest B6 Coupe and Convertible models which receive the usual ALPINA treatment and significant power upgrade.

The B6 BiTurbo produces 540 horsepower from the standard 407 hp and uses a revised 4.4 liter V8 twin-turbo engine. The torque sent to the rear wheels accounts for 700 Nm.

The engine is mated to an eight-speed ZF automatic transmission that takes the B6 Coupe from 0 to 100 km/h in 4.4 seconds and has a maximum speed of 320 km/h. The B6 BiTurbo convertible runs the same distance in 4.5 seconds and has a top speed of 317 km/h.

The coupe also comes equipped with the Akrapovic exhaust system that provides increased acoustics. To cater to all type of customers, the B6 Coupe uses the Adaptive Drive system from BMW that with a push of a button changes the suspension settings and throttle response.

ALPINA B6 Coupe and Convertible sit on 20-inch wheels and uses 255 millimeters wide tires at the front axle and 285 mm wide a the rear.
