Last updated August 4, 2026

About the 2012 Mercedes-Benz SLS-Class
1st generation (C197 coupe / R197 roadster), second U.S. model year; Roadster debut year.
Mercedes-Benz positioned the SLS as its true in-house AMG supercar: a dramatic, long-hood two-seater inspired by the 300 SL but engineered with modern racing ideas. The appeal was not just speed. It paired a hand-built naturally aspirated V8, low-weight construction, and attention-grabbing design with a cabin that felt richer and more usable than many stripped-down exotics. For most buyers, the SLS was the Mercedes supercar that delivered both theater and real road comfort.
The 2012 SLS-Class is AMG's flagship sports car in coupe and open-top roadster form, with the same upscale cabin and high-performance hardware in both. Its signature equipment includes a hand-built 563-hp 6.2-liter V8, a quick-shifting seven-speed automatic, a lightweight aluminum structure, navigation, and heated leather sport seats.
