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. Standard advanced safety features include forward collision warning, automatic emergency braking with pedestrian and cyclist detection, and blind spot warning.
