BMW's super-luxurious three-row SUV has a standard turbo six-cylinder engine and smooth eight-speed automatic transmission. This is a gem of a powertrain that provides punchy acceleration and respectable fuel economy. Its comfortable ride is helped by the X7's air suspension which keeps the body composed; the handling is remarkably responsive for such a large SUV. The cabin is incredibly quiet and has a richly furnished interior. Buyers can choose between two second-row captain's chairs or a three-person bench seat. BMW's latest iDrive infotainment system is easier to use than in previous versions, but it still takes some getting used to. An M50i version with a 523-hp, turbo V8 engine was new for 2020. For 2023, the X7 got an extensively revised front end, a restyled interior with an updated iDrive 8 infotainment system, and the xDrive40i received a 40-horsepower increase to 375.
