A guy from the M5board Forums is the lucky owner of a black Alpina B7. Based on the BMW 7 Series, the B7 brings together the luxury, pioneering design, and advanced technology of the 7 Series Sedan with the scintillating performance of a supercharged, 500hp V-8 engine.

To power the BMW ALPINA B7, ALPINA specially developed a higher-performance version of BMW's 4.4-liter, 90-degree V-8 engine and mated it to a 6-speed automatic transmission featuring steering wheel mounted shift controls. The motor produces 500 horsepower at 5,500 rpm along with maximum torque of 516 lbs.-ft. at 4,250 rpm, and propels the B7 from 0-60 mph in a mere 4.8 seconds. ALPINA 21-inch wheels carry Z-rated performance tires, while the sport-tuned suspension includes Active Roll Stabilization. The B7 aerokit includes a rear spoiler to improve stability, handling, and performance at high speeds.

Be afraid CLS rocket, you now have a worthy opponent.
