The highlight of our transmission technology is standard in C 320 CDI 4MATIC, C 350 and C 63 AMG – and optional for all other 6-cylinder models: the 7G-TRONIC 7-speed automatic transmission. Seven forward gears constantly provide optimum engine speed and deliver virtually imperceptible gear changes. When changing down, the 7G-TRONIC – unlike other automatic transmissions – delivers extra-fast mid-range sprints by skipping individual gears. By simply nudging the selector lever, you can also shift gear manually.
