2011 Mercedes-Benz SLK: What's New, Specs & Features
Last updated August 4, 2026

The main change for the 2011 Mercedes-Benz SLK is that sport body styling becomes standard on both remaining trims. It is otherwise a light final-year update for this generation, with the SLK 55 AMG dropped and no redesign or major mechanical overhaul.
About the 2011 Mercedes-Benz SLK
Second generation (R171), final U.S. model year before the all-new 2012 redesign.
Mercedes-Benz positions the SLK as a compact luxury two-seat convertible that blends sports-car flavor with everyday comfort. Its signature feature is the folding metal roof, which gives it coupe-like security and quiet when closed, then open-air driving in seconds when lowered. Compared with softer convertibles, the SLK leans into sharp looks, V6 performance, and Mercedes safety engineering, while offering more year-round usability than a fabric-roof roadster.
The 2011 SLK is a two-seat convertible with a power-folding hardtop and leather-trimmed sport seats. The SLK300 emphasizes a lighter, simpler feel with a 228-hp V6, while the SLK350 adds a 300-hp V6, a seven-speed automatic, stronger front brakes, and larger wheels. Both have dual-zone climate control and the newly standard sport exterior.
