The rear-wheel-drive 2011 BMW Alpina B7 sedan previously debuted in February, at the 2010 Chicago Auto Show. The Alpina B7 will be available in both short- and long-wheelbase versions for both the regular and xDrive all-wheel-drive models.
BMW's "intelligent" all-wheel-drive system, xDrive, is the only change from the B7 sedan seen at the Chicago show. The B7 has a twin-turbocharged 4.4-liter V8 that makes 500 horsepower and 516 pound-feet of torque.
