BMW announced pricing for the 2008 Alpina B7: $115,775. The B7 is based on the BMW 7 Series luxury sedan.

BMW itself offers a 7 Series model powered by a 438-horsepower V-12 engine, the 760Li. It is indeed a high-performance car, combining the velvety and high-torque power delivery of a 12-cylinder engine with ultimate luxury. For an unabashedly sporty interpretation of the 7 Series, ALPINA chose the path of supercharging BMW’s V-8 engine.

By selecting as the basis for the B7 the BMW 750i, with its V-8 engine and regular-wheelbase platform, ALPINA could achieve a vehicle weight some 400 pounds lighter than that of the 760Li – a benefit in terms of agility and maneuverability. Then, to attain a power target of 500 hp, ALPINA added a supercharger to the V-8 engine, which adds little weight but lots of horsepower.

At the time ALPINA began development of the B7 engine, BMW’s V-8 engine with Valvetronic – the unique system that regulates power output by varying intake-valve lift – was at a 4.4-liter displacement in the 745i, not the 4.8 liters of today’s 750i. Therefore, the engine package was based aroung 4.4-liter’s 325 hp @ 6100 rpm and 330 lb-ft. of torque @ 3600 rpm.
