The permanent AWD system is based on the same set-up used in the larger S-Class saloon, which officials claim is one of the lightest AWD systems in the world, adding just 70kg to the CL’s kerb weight. According to Germany’s Auto Motor und Sport, both fuel consumption and straight line speed are almost the same as the RWD model, which means the 0-100km/h sprint is completed in just 5.4 seconds and mileage remains at 19.5mpg (12.1L/100km). Top speed remains limited to 250km/h.
The 4MATIC system features a planetary-type center differential and splits power between the front and rear wheels in a ratio of 45 to 55%. An integrated multiplate clutch ensures additional traction and the combination of Mercedes’ standard traction control and braking systems helps make the AWD mega-coupe one of the safest vehicles on the road.
