The first nine-speed automatic transmission with torque converter, the 9G-TRONIC for premium vehicles, is celebrating its world premiere. Equipped with the innovative power transmission, the E 350 BLUETEC is set to become one of the most fuelefficient six-cylinder diesel models in its class. Thanks to the high level of efficiency of the patented transmission design, NEDC fuel consumption in the E-Class is reduced to 5.3 liters of diesel per 100 km. As is typical of the brand, the transmission features outstanding comfort and barely perceptible gear changes. The E 350 BLUETEC featuring the 9G-TRONIC as new standard and is available to order in continental Europe with immediate effect. Essential objective of the functionality of the new transmission are quick and comfortable shifts. Basics for quick and comfortable shifts are specifically designed transmission hardware. In the 9G-TRONIC therefore small volumes for the pistons of the shift elements are implemented. The oil flow in the transmission to the elements was optimized by a fast reacting electrohydraulic control. For the first time a direct control unit is applied. A moderate acceleration of the E350 BLUETEC with 9G-TRONIC in comparison to the 7G-TRONIC is shown. The main advantage can be seen in the velocity range from 40 km/h to 100 km/h, where the low engine speed is still possible, due to high number of gears and the high ratio spread. Especially under customer driving conditions significant fuel economy improvements are possible.
