The 2010 BMW X6 is a midsize luxury crossover that inaugurates the Sports Activity Coupe (SAC) genre. It's available in two trims: the xDrive35i and the xDrive50i. The xDrive35i runs on a 3.0-liter turbocharged inline-six engine making 300 horsepower, while the xDrive50i boasts a 4.4-liter twin-turbocharged V8 generating 400 horsepower. BMW pairs both engines with a six-speed automatic transmission and an all-wheel-drive system. Premium features include 10-way power-adjustable front seats, a power liftgate, and parking sensors. For infotainment, there’s a knob-based iDrive interface with a 6.5-inch display, a 10-speaker sound system, and HD Radio. In terms of safety, BMW equips the 2010 X6 with stability and traction control systems, among other notable features. Yet, it's the X6's unique combination of sporty dynamics, SUV capabilities, and coupe-like aesthetics that sets it apart.
