For both the 6-cylinder models, CLC 230 and CLC 350, the automatic transmission 7G-TRONIC is optionally available. Its seven forward gears allow small shifts in engine speed for an optimum transmission ratio – and thanks to multiple downshifting, several gears can even be skipped. Fast shifting with smooth gear changes and reduced fuel consumption are the unmistakable advantages of the 7G-TRONIC. That's attractive, and not just to sporty drivers.
