The 2020 X6 is a coupelike, sporty SUV that's based on the redesigned X5. The smooth 3.0-liter turbo six-cylinder engine and eight-speed automatic make it quick, and our tested X5 got a good 23 mpg overall. The luxurious cabin is whisper-quiet, and the seats are all-day comfortable. Handling is very competent, but the X6's ride is stiffer than the X5's. The controls take time to learn but prove to be logical, and the infotainment system works seamlessly. Unlike its sibling, the X6's styling severely hampers rear visibility, rear-seat access, and cargo room. A rear-wheel-drive version is also available, as is a V8-powered M50i. A 2024 refresh brought updated styling, more power, and the latest iDrive infotainment system.
