Geared up: 7G-TRONIC as standard in all models
All Mercedes R-Class models are equipped with the latest-generation of the innovative 7G-TRONIC automatic transmission. The Fuel Efficiency variant of the seven-speed transmission has new bearings and couplings. Different oil pressures and a new, low-friction oil help to reduce friction and churning losses. The new torque converter with slip-reduced lockup clutch likewise improves efficiency and aids fuel economy. In addition, standstill decoupling lowers fuel consumption. This technical feature reduces transmission input torque in "D" when the car is at rest, for example at traffic lights. This lowers the stress on the engine, making for lower fuel consumption, better vehicle acoustics, greater comfort at standstill and smoother idling. The slip-controlled clutch is engaged as soon as the driver releases the operating brake, ensuring no delay or quality compromise when the vehicle moves off.
