2017 Mercedes-Benz SLC: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for 2017 is that the Mercedes-Benz SLK becomes the SLC as part of a mid-cycle refresh. The renamed roadster also gets updated styling and cabin tech, while the AMG version switches from V8 to twin-turbo V6 power.
About the 2017 Mercedes-Benz SLC
3rd gen R172 (2012-2020 overall), first year sold in the US as SLC after the 2017 rename and mid-cycle refresh.
Mercedes-Benz positions the SLC as a compact luxury roadster that mixes open-air fun with everyday comfort. Its big differentiator is the folding hardtop, which gives it a quieter, more coupe-like feel when closed than many soft-top rivals. Compared with sharper, more track-focused two-seat sports cars, the SLC leans toward polished cruising, upscale cabin feel, and easy day-to-day drivability while still delivering quick turbo power and rear-wheel-drive balance.
The SLC 300 is the everyday luxury-sport version, with a 241-hp turbocharged four-cylinder engine, a nine-speed automatic transmission, and five drive modes. Its retractable hardtop has a panoramic roof panel, while power sport seats and a 7-inch center display add everyday comfort and convenience.
