The 750i and long-wheelbase 750Li are powered by a direct-injection, 400-hp 4.4-liter, twin-turbo V8 bolted to a six-speed automatic transmission with manual shift control. The 750 has many standard luxury features such as four-zone automatic climate control, power sunroof, high-gloss wood trim, heated 16-way multi-contour seats, voice-activated navigation system on a 10.2-inch color monitor, HD radio and BMW Assist emergency and information communications. Standard run-flat tires wrap 18-inch alloy wheels, while standard Park Distance Control, adaptive brake lights and steerable adaptive bi-xenon headlights provide active safety. High-tech options include rear and side-view cameras, power trunk lid, high-beam assistant, lane departure warning, blind spot detection, dual LCD screens for rear seat entertainment and ventilated front seats. For 2010, BMW's xDrive all-wheel drive system is now available on both the 750i and 750Li.
