Mercedes Benz Cl 550 4 Matic 2009 GalleryGiving the CL greater traction - and therefore better low-grip handling - the coupe's permanent 4Matic all-wheel drive system helps the CL appeal to snow-belt drivers by splitting torque between the front and rear axles at a 45/55 ratio. The CL's center differential uses a twin-plate clutch to manage the torque distribution between the front and rear axles.
