The BMW X6 is a four-passenger luxury crossover or "sports activity coupe" as BMW likes to call it. It went on sale in the second quarter of 2008 with a promise of combining the benefits of an SUV and a coupe into one convenient little package. The current X6 is powered by a plethora of engine options. The first is a 3.0L twin turbo engine producing 300/320hp and 300 lb-ft of torque. The second engine is a 4.4L twin turbo V8 delivering 400/440hp and 450 lb-ft of torque. The 4.4L V8/electric hybrid option pushes out 480 net ho and 575 net lb-ft of torque, while on the opposite side of the spectrum is the 4.4L twin turbo V8 that gets 555hp and 500 lb-ft of torque. These engines are mated to a six-speed automatic, continuously variable transmission.
