Last updated August 4, 2026
The main change for the 2014 Mercedes-Benz SLK is that the Panorama glass roof becomes standard on the SLK 250 and SLK 350. Otherwise, this is a light update with the same three-trim lineup and engines as 2013.
About the 2014 Mercedes-Benz SLK
3rd gen (R172), fourth model year; light-update year before the final pre-facelift stretch.
Mercedes-Benz positions the SLK as a compact luxury roadster that blends sports-car style with everyday comfort and coupe-like usability. Its defining idea is the folding hardtop, which gives open-air driving without the noise and weather tradeoffs of a fabric roof. Compared with rivals, the SLK leans toward a more polished cabin, a quieter highway character, and easy grand-touring manners, while still offering sharp handling and, in AMG form, serious performance.
The SLK 250 is the relaxed entry model, with a 201-hp turbo four-cylinder engine and a standard manual transmission. The SLK 350 adds a 302-hp V6, leather, heated seats, neck-level heating, and surround sound, while the SLK 55 AMG tops the range with a hand-built 415-hp V8 and sharper AMG-tuned handling.
