Nine-Speed Automatic Transmission 9G-Tronic by Mercedes-Benz
Daimler has designed the first nine-speed automatic transmission for longitudinal applications. The 9G-Tronic debuts in the Mercedes E 350 Bluetec and will be introduced in other models later on. Thanks to the higher efficiency of the patented transmission concept, the NEDC consumption of the E 350 Bluetec drops to 5.3 litres Diesel per 100 km. The improvements are primarily due to the new gear set and the on-demand actuation concept with a small main pump and electric auxiliary pump.
