The difference compared to the stock 7-series is the engine. Current 2009 750i has a 400 hp 4.4-liter twin-turbo V8 with 405 lbs-ft and Alpina will boost the power to over 500 hp.
Rumor is that this 4.4-liter twin-turbo V8 in the Alpina B7 will also get the new eight-speed transmission not the six-speed automatic in the 750i.
Production version of the Alpina B7 will likely get 21-inch wheels, larger brakes and a modified chassis for better handling.
