For 2017, the updated SLK also gets a new name: SLC. It features a retractable hardtop that does a great job at keeping the interior quiet. The SLK250 we tested had a 1.8-liter turbo four-cylinder that delivered ample thrust, and the new SLC300 uses a more powerful 2.0-liter engine coupled to a nine-speed automatic. There is a more powerful V6 SLC43 version.

2017 Mercedes-Benz SLC RoadsterFreshened retractable hardtop convertible adds safety and technology

Overview

Mercedes-Benz continues to revitalize, and rename, its product line, with the latest example to be the transformation of the SLK retractable hardtop into the SLC. By adopting the classic SLC moniker, the brand is recognizing the roadster's C-Class pedigree while aiming to better align the models in its range. Some may recall that the SLC was a 2+2 coupe version of the SL from the late 1970s and early 1980s.

Impressions Of course, the new SLC variants will still feature the SLK's pioneering "vario-roof," a mechanical feat that defined the roadster as one the first retractable hardtop convertible sports coupes sold. The top can now deploy or retract at speeds up to 25 mph.
