<p>The E 63 S is equipped with the innovative AMG Performance 4MATIC+ all-wheel drive system. This newly engineered, intelligent system brings together the advantages of various drive configurations. Torque distribution on the front and rear axles, which is fully variable for the first time, ensures optimum traction right up to the physical limit. The driver is also able to rely on high driving stability and handling safety under all conditions. The transition from rear-wheel to all-wheel drive and back again is seamless, because intelligent control is integrated into the vehicle system architecture as a whole. It is still possible to drift thanks to fully variable torque distribution. </p>
