The 4.4-litre V8 engine in the Alpina B6 Bi-Turbo Gran Coupe develops 540bhp and a high 730Nm of torque available between 2,800 and 5,000rpm. The bi-turbo lump is linked to a capable ZF eight-speed transmission with Alpina Switch-Tronic for a creamy power delivery.

Bundled with BMW's xDrive all-wheel drive technology, the B6 Gran Coupe blasts to the century mark from nought in a dizzying 3.9 seconds and on to a top speed of 318km/h - making it the fastest accelerating BMW Alpina to date. Direct injection and valvetronic contribute to the B6 Bi-Turbo Gran Coupe's low consumption and emission figures of just 9.6km/L and CO₂ emissions of 242g/km in the combined cycle.

Typical design features of Alpina blend seamlessly and elegantly into the contours of the Gran Coupe and accentuate its sporty, powerful appearance. In particular, the 20-inch Alpina Classic light alloy wheels complement the long, smooth proportions of the Gran Coupe.

The front spoiler with integrated, slightly forward positioned splitter directs more air over and around rather than underneath the vehicle, thereby stabilising the front end at high speeds. The design of the front spoiler ensures the effective flow of sufficient air to various radiator modules of the performance cooling systems.

The Blue Alpina instruments, hand stitched steering wheel in Lavalina leather and illuminated door sills are just some of the exclusive features of the Gran Coupe's interior.

The stainless steel exhaust system with trademark twin pipes returns a deep exhaust note - while an optional titanium exhaust system from Akrapovic is also available.
