Alpina officially unveiled the new BMW Alpina B7 Bi-Turbo at Geneva yesterday, and we have the full details inside.

Alpina has unveiled the new BMW Alpina B7 Bi-Turbo, the fourth generation of an Alpina spec BMW 7-Series. With this car, Alpina is aiming for a perfect balance of "exclusiveness, athleticism and comfort."

It looks like they have executed their plan perfectly. The B7's athleticism begins with its 4.4-liter V8 engine, that produces 507 hp with a monstrous maximum of 700 Nm of torque. 0-100 km/h in 4.7 seconds, and an electronically limited top speed of 280 km/h means the car is both quick and fast. High performance pistons were put in place to deal with the 1.0 bar maximum turbo boost. Two new large-vane turbochargers have been mounted with an optimized intercooler system. In the end, the vehicle receives an impressive 115hp output per liter. The driver controls this power through a ZF six-speed automatic sport transmission, which uses Alpina's Switch-Tronic system to adapt to the driving situation.

Comfort comes in many forms on the B7, from the unique springs that reduce ride height, to the leather accoutrements inside. The car makes due with 21-inch wheels, and a suspension system that is as responsive, but softer, than a race suspension. Conventional tires have also been used in place of run-flats. The electronic suspension has been tuned and adjusted for each of its three settings (Comfort, Normal, and Sport).

The luxury Myrtle Burl wood trim or optional Piano Lacquer interior give two distinct and distinguished looks to the car. The illuminated doors and Lavalina leather steering wheel also adds an element of exclusivity.

So too does the price tag. A new BMW Alpina B7 Bi-Turbo will easily top the B7 sedan's $115,000 sticker price. You can read the full equipment offerings and specs in the press release below.
