The BMW X6 is available in two trim levels: xDrive35i and xDrive50i. The xDrive35i is powered by a 300-hp 3.0-liter inline six-cylinder engine, while the xDrive50i boasts BMW's first production turbocharged V8, generating 400 horsepower and 450 pound-feet of torque. Both engines feature twin-turbo and direct fuel injection technologies, and are paired with a six-speed Sport automatic transmission with Steptronic manual shift mode and steering wheel paddles. Exclusive to the X6, BMW's Dynamic Performance Control is standard on both trims, distributing drive force between the rear wheels and enhancing its sporty handling characteristics. Additional standard equipment includes 19-inch alloy wheels, a power moonroof, bi-xenon adaptive headlamps, automatic climate control and leather upholstery; the xDrive50i is further outfitted with a voice-activated navigation system (optional on the xDrive35i). Safety features on every X6 include anti-lock disc brakes, Dynamic Stability Control with traction control and rollover sensor, front and rear parking sensors and a tire pressure monitor, as well as front side-impact airbags and overhead curtain airbags for both rows. For 2010, the BMW X6 gets HD radio added to standard equipment on both trim levels, along with a power rear liftgate.
