The new BMW Alpina B6 Gran Coupe BiTurbo will debut later this year and here we have the clearest spy shots showing the luxury Gran Coupe testing at the Nürburgring.
Alpina is not another BMW tuner, their cars go through extensive testing and are produced on the same assembly line as the BMW models they are based on. Alpina is in fact an automobile manufacturing company selling their own cars, which are based on BMW cars.
The upcoming Alpina B6 Gran Coupe BiTurbo reveals us a new front bumper, typical Alpina wheels, rear spoiler, new double exhausts on each side as well as a new rear bumper with a new diffusor. The interior will be updated as well with new upholstery, seats and instrument panel gauges.
The B6 Gran Coupe Bi Turbo is based on the 650i and will be positioned between the 443bhp 650i and the 552bhp M6 Gran Coupe. Power comes from a modified 4.4-litre twin-turbo V8 producing 532bhp and 730Nm of torque. The chassis will be updated as well to improve the handling.
