Mercedes-Benz will be introducing the all new 9-speed automatic transmission in the new E-Class, which will go on sale in the European market this September. The new transmission won’t be available in the UK market until next year. For the time being, the E-Class will get introduced to the new transmission and eventually the carmaker will update the rest of the lineup intended to feature the new 9G-TRONIC transmission, which replaces the old 7G-TRONIC transmission.
Replacing the old 7-speed 7G-TRONIC, the new transmission offers improved fuel efficiency and CO2 emissions. The high-tech gearbox will get mated to the E350 BlueTEC first. The CO2 emissions of the specific model have dropped from 157 g/km to 138 g/km. The fuel economy has improved from 20 km/l to 22 km/l. The 9G-TRONIC has also increased the refinement level to a great extent. The German automaker claims that the engine is spinning at just 1350 RPM while driving at 120 km/hr in top gear.
Compared to the outgoing transmission, the 9G-TRONIC is lighter but the size of the transmission hasn’t changed and the acceleration also remains unchanged. The new gearbox can handle up to 1000 Nm of torque unlike 7G-TRONIC and it will be able to be fit in all of the AMG spec Mercedes models. At present, the S65 and CL65 AMG are mated to a 5-speed automatic rather than the 7G-TRONIC to handle the massive torque on offer. The addition of 9G-TRONIC gearbox won’t affect the price of the vehicles. We expect Mercedes to introduce the new transmission in India next year.
