Another debut at last month’s Geneva Motor Show was the 2012 ALPINA B6 BiTurbo, in both Coupe and Cabriolet variants. The two super-sporty and luxurious models receive the usual ALPINA treatment, along with a 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.

Both models are only available for European customers.
