There are no changes of note to the 2008 BMW 7-Series lineup, which includes the 750i, 750Li, Alpina B7, and 760Li. The "L" versions of BMW's flagship sedan ride a 5.5-inch-longer wheelbase. The 750i and 750Li have a 360-hp V8. The Alpina B7 has a supercharged 500-hp 4.4-liter V8. The 760Li has a 438-hp V12. All 7s have a 6-speed automatic transmission with steering wheel buttons for manual control. ABS, traction control, antiskid system, and BMW's Active Roll Stabilization designed to counter body lean are standard. So are front knee airbags, front side airbags, and head-protecting tubular side airbags. Rear side airbags are optional. Included on 760Li and optional for 750s is an Adaptive Ride Package with driver-adjustable suspension. V8s offer an optional Sport Package with firmer suspension and 20-inch wheels. A navigation system and wireless cell phone link are standard, as is BMW's iDrive control for audio, navigation, and climate settings. The Alpina B7 includes sport suspension, uprated brakes, 21-inch tires, heated and cooled front seats with 20-way power adjustment, and keyless access and starting. All models include steering-linked headlights, front/rear obstacle detection, and BMW Assist emergency/concierge service. Also available are DVD entertainment and keyless entry and starting.
