2011 BMW Alpina B7 @ 2010 Chicago Auto Show Video

The Alpina B7 is back, ready to make its official debut at the 2010 Chicago Auto Show. The 2011 BMW Alpina B7, based on the current BMW 750i, goes on sale in the U.S. in the spring of 2010.The last B7 we drove had a supercharged 4.4-liter V8 good for 500 horsepower and and 516 pound-feet of torque. Curiously, the 2011 BMW Alpina B7 achieves exactly the same result with a tuned version of the current 7 Series' twin-turbocharged and direct-injected, 4.4-liter V8. The torque curve is flatter in the new B7, though, with all 516 lb-ft available from 3,000-4,750 rpm.
