The best feature of an assembly is solidarity. The 7-speed 7G-TRONIC automatic transmission and the 4MATIC four-wheel drive operate on this principle. The objective of the 7G-TRONIC is to engage the gear best suited to the driving situation and your driving style at all times. The operating style of the transmission is based on acceleration and comfort. You can change gears also manually by pressing a button. The 4MATIC permanent four-wheel drive system helps you to remain in your lane on poor roads. If the load is not distributed evenly to the wheels on bumpy roads and there is risk of the wheels spinning, specific braking interventions by the electronic system ensure the rebalancing of the load immediately. The electronic driving dynamics system (4 EPS / 4 ETS) with integrated ABS and ASR functions and which supports the four-wheel drive effect guarantees the best possible traction.
