The X6 prioritizes style over versatility. Compared to the more conventionally shaped X5, it offers less interior space, especially for rear passengers, and the trunk is considerably smaller (776 litres instead of 960). Three trim levels are available: the xDrive40i with a 375-horsepower six-cylinder engine, the M60i with a 523-horsepower V8, and finally the explosive 617-horsepower X6 M Competition. Unlike the X5, there is no plug-in hybrid option with the X6.
