The SLK stands for dynamic performance and agility at the highest level. Drivers who enjoy life in the fast lane also need to be able to shift gears quickly. That's why the power of individual engines is transmitted through transmission systems harmonised with the temperament of each vehicle model.

The SLK 350 BlueEFFICIENCY comes with the optimum-efficiency 7G-TRONIC PLUS 7-speed automatic transmission as standard; also for the SLK 200 BlueEFFICIENCY and the SLK 250 BlueEFFICIENCY.
