500HP, Tweaked Chassis, and Bodykit Create Uber 7
Though announced by BMW North America last year, the BMW Alpina B7 finally arrived at the 2007 Chicago auto show. The B7 Alpina is a superfast version of the regular-wheelbase 750i, created by longtime BMW tuner Alpina from the 750i and fully warranted by BMW. The prior 745i was offered with a 325HP 4.4L Valvetronic V8, and it is this engine that Alpina supercharged to 500HP and 516 lb-ft. of torque. To go along with the power, the B7 Alpina sports cosmetic cues and Alpina badges inside and out.
Along with supercharging a Valvetronic engine for the first time, which required specific engine enhancements, Alpina tweaked the suspension. There is firmer calibration of springs and shock absorbers, created a new exhaust system, the 7′s Active Roll Stabilization for countering body roll in corners, the European 760i’s larger brakes, and twenty-inch wheels and tires. Alpina strengthened the differential, but the full torque is still limited to the first two gears of the six-speed automatic transmission.
Outside, B7 Alpina’s subtle cues include a specific front bumper and spoiler, twenty-spoke Alpina wheels, a rear spoiler, and Alpina B7 badges. As pictured, the traditional Alpina blue metallic paint is available. Interior touches include B7 doorsill trim, blue background color for the instrument cluster, and Alpina lettering. The steering wheel sports an Alpina logo, is trimmed with Lavalina leather, and has upshift/downshift buttons.
