The BMW X5 is a mid-size crossover SUV produced by the German automaker BMW. The vehicle was unveiled in 1999 at the Detroit Auto Show. The "X" stands for all-wheel drive, and the "5" indicates that the vehicle is based on the 5 Series (BMW E39). The X5 is shorter than the E39, but taller and wider. The E53's body is reminiscent of the BMW E46. The vehicle is suitable for driving on all types of road surfaces, thanks to its high ground clearance and permanent all-wheel drive. The BMW X5 E53 was developed when BMW Group already owned the Land Rover brand, and as such, it shares many components and design features with the Range Rover L322, including the Hill Descent and Off-Road systems, as well as the engine and electronic systems from the BMW E39. Unlike the Range Rover, the first X5 was developed as a sports car, and its off-road capabilities are significantly less than those of the Land Rover.
