A sport-themed model is a midyear addition to BMW's large sedan lineup for 2007. The 7-Series comes in regular-length and 5.5-inch-longer L models. The 750i and 750Li have a 360-hp 4.8-liter V8. The 760Li has a 438-hp 6.0-liter V12; the 760i is dropped. Added midyear is the sporty Alpina B7, which has a supercharged 500-hp 4.4-liter V8. All 7s have a 6-speed automatic transmission with steering wheel buttons for manual control. Also standard are ABS, traction/antiskid control, and BMW's Active Roll Stabilization designed to counter body lean. Included on 760Li and optional for 750s is an Adaptive Ride Package with driver-adjustable suspension. The 750 offers an optional Sport Package with firmer suspension and, for '07, 20-inch wheels. B7s have specific interior and exterior trim, 21-inch tires, and even sportier suspension tuning. All 7-Series models include front knee airbags, front side airbags, and head-protecting tubular side airbags. Rear side airbags are optional. A navigation system and wireless cell phone link are standard. So is BMW's iDrive control for audio, navigation, and climate settings. Standard power folding door mirrors are new for '07, and 750s gain heated 16-way "comfort" front seats. All models include steering-linked headlights, front/rear obstacle detection, and BMW Assist emergency/concierge service. Newly optional are BMW Individual packages with various mixes of trim and features. Also available are DVD entertainment and keyless entry and starting., , Inside the 2007 BMW 7 Series, the cabin has the expected opulent atmosphere and a clean layout, thanks to the minimal center stack controls. The iDrive system was designed to consolidate the vehicle's control systems into one easy-to-use interface, but the learning curve is steep. Most basic adjustments can be made rather easily, but more complex functions require time with the owner's manual and patience to learn -- and we know of more than one driver who has accidentally drifted out of his lane while fiddling with iDrive. Materials are generally very high in quality, as you'd expect in this class, but there are a few plastics here and there that seem out of place in an executive sedan. Backseat passengers will be just as comfortable as those in front, as the rear seatback contours perfectly to support your lower back and shoulders, while headroom and legroom are abundant. Go for the 750Li and you'll get an extra 6 inches of rear-seat legroom.
