The BMW E70 is the second-generation BMW X5 mid-size luxury SUV. It replaced the BMW X5 (E53) in July 2006. It was manufactured alongside the BMW X6 at BMW's Greer, South Carolina plant in the U.S. and BMW's facility in Toluca, Mexico.

The xDrive AWD system updates previewed in the facelifted X5 have continued with further detail improvements for the E70. It uses a double wishbone suspension at the front.[3] The manual transmission is entirely dropped, leaving only the automatic transmission. The E70 features many new technological advancements for this class as standard equipment including BMW's iDrive system, electronic 'joystick' gearshift (no mechanical connection to the gearbox to save space in the console), LED taillamps, the first ever all-polypropylene single module fender module,[4] and options such as heads-up display (HUD), active steering, active damping, and Dynamic Drive which uses active anti-roll bars employing a hydraulic servo in the middle to actively counteract body roll.[3] The X5 has a rollover risk of 17.4%.
