The new 4MATIC AWD system enhances safety on wet and icy surfaces, snow and roads with poor stability. Instead of working with conventional differential locks, the new 4MATIC uses a state-of-the-art electronic system. 4MATIC distributes 45% of engine power to the front axle and 55% to the rear axle – to ensure 100% traction. In doing so, 4MATIC permanent AWD deploys the electronic stability program ESP® and electronic traction-control system 4ETS.
4ETS precisely and systematically brakes spinning wheels and enables the vehicle to move off and accelerate with power – even in adverse weather conditions or on poor road surfaces.
The diesel engine in the S 320 CDI and the petrol engines in the S 350, S450 and S 500 are available with 4MATIC permanent all-wheel drive.
