The Alpina B7 is based off of the BMW 7-series. The interior is almost identical to the 760Li and it has been given slight external modifications to set it apart from other 7-series. Performance tuning is where the Alpina B7 stands alone. It is powered by a supercharged 500 hp 4.4-liger V8 engine. This power is controlled by an Alpina six-speed automatic transmission with manual gear select paddles. Connecting the sedan to the road are four massive cast-alloy 21-inch wheels.While the BMW Alpina B7 has been available in Europe since 2004, it is brand new for Northern America in 2007.
