The BMW X6 is available in two trim levels: xDrive35i and xDrive50i. The xDrive35i is powered by a 300-hp 3.0-liter turbocharged inline six-cylinder engine, while the xDrive50i boasts a twin-turbo V8, generating 400 horsepower and 450 pound-feet of torque. Both engines feature direct fuel injection, and are mated to an eight-speed Sport automatic transmission with Steptronic manual shift mode and steering wheel paddles. Additionally, BMW's Dynamic Performance Control is standard on the X6, distributing drive force between the rear wheels and enhancing its sporty handling characteristics. Other standard equipment includes 19-inch aluminum wheels, a power moonroof, power liftgate, bi-xenon adaptive headlamps, automatic climate control, leather upholstery and HD radio; the xDrive50i is further outfitted with multi-contour seats and a voice-activated hard drive-based navigation system, including 12 gigabytes of dedicated media storage and DVD video capability (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. The BMW X6 carries over with minimal changes for 2012. Enhanced standard equipment includes privacy glass, auto-dimming mirrors, heated front seats, BMW Assist with Bluetooth and a USB port. Additionally, a new rear middle seat option increases capacity to five passengers.
