Mercedes-Benz has renamed and revamped a number of its vehicles over the course of the past year, and that will continue into the 2017 model year with models like the new Mercedes-Benz SLC. While the degree of the changes has varied, one common theme is the addition of a 9G-TRONIC 9-speed automatic transmission.
As an evolution of the 7G-TRONIC 7-speed automatic transmission found in most previous generation models, the new 9-speed version helps boost efficiency and performance. But before diving into the technical details, let’s get a better understanding for the Mercedes-Benz 9G-TRONIC transmission.
What is a Mercedes-Benz 9G-TRONIC Transmission?
Mercedes-Benz is always searching for ways to get more from its vehicles, and the new 9G-TRONIC transmission helps do that in a number of ways. As the first nine-speed automatic transmission in the premium vehicle category to feature a hydrodynamic torque converter, which transfers torque using fluid rather than a mechanical clutch, Mercedes-Benz is once again at the cutting-edge of the automotive world.
Mercedes-Benz 9G-TRONIC transmissions include three selectable drive programs — economic, dynamic and manual. While economic and dynamic are largely self-explanatory, manual puts the power in the hands of drivers, as shifts can be made using steering-wheel-mounted paddle shifters.
Efficiency gains come from the wide gear ratios and the lightweight construction of the transmission itself. Despite the two additional gears, Mercedes-Benz engineers managed to install it in the same space in which its 7-speed predecessor was housed.
The wide-range of gears also allows for lower revs, which helps increase efficiency, especially in highway driving.
More Dynamic Performance
In terms of performance, the 9G-TRONIC 9-speed automatic transmission is capable of skipping individual gears when downshifting, providing quicker accelerations and faster sprints.
In the utility segment, and perhaps in other segments of the Mercedes-Benz lineup in the future, models equipped with the 9G-TRONIC 9-speed automatic transmission also include DYNAMIC SELECT. With DYNAMIC SELECT, drivers can choose between a variety of driving modes that fine-tune key driving systems, including the transmission, to personalize performance.
Currently, the new Mercedes-Benz 9G-TRONIC 9-speed automatic transmission is available in all the recently refreshed utility vehicles, and it will continue to make its way into more Mercedes-Benz models as they get refreshed and redesigned in the coming years. In the meantime, take a closer look at these utility vehicles equipped with the new transmission.
