The X6 is a coupe-like sporty SUV based on the X5. Most versions are powered by a 3.0-liter, turbocharged six-cylinder; a 4.4-liter turbocharged V8 is also offered. The standard AWD system can vary the torque from side to side to minimize understeer. It has many attributes that are similar to the X5, but the styling severely hurts rear visibility, cabin access, and cargo storage. The standard seating is four occupants; a five-passenger version is optional. A high-performance M model is also available.
