The CLS-Class is fitted with the 7G-Tronic as standard for impressive acceleration and faster gear changes. This automatic transmission – another Mercedes-Benz world first – has seven forward gears for smoother, faster gear changes.

The use of seven transmission ratios creates a larger spread between the lowest and the highest ratio while at the same time an optimal, close-ratio configuration is maintained. The reduction in average engine speeds benefits fuel consumption as well as reducing noise.
