A classic example of form over function, the X6 was one of the first coupe-style luxury crossovers to hit the market. New body colours are available for 2023, while options and packages have been revised. Powertrain selection is similar to the more conventional X5 except for the plug-in hybrid system, which the X6 can’t have. The star in the lineup is the high-performance X6 M Competition, whose twin-turbocharged V8 engine cranks out 617 horsepower.
