Mercedes-Benz SLK-Class Roadster · 2nd generation SLK
Sharper looks, a stiffer body, and — finally — a proper AMG V8.

Launched for the 2005 model year, the second-generation SLK retained the folding Vario hardtop but wrapped it around a new platform shared with the C-Class, with a four-cylinder Kompressor entry point and six-cylinder power through the rest of the range, plus revised proportions that dropped the round headlamps for a sharper face.
The SLK 55 AMG, powered by AMG’s naturally aspirated 5.4-liter M113 V8, topped the line-up — later joined by an ultra-limited Black Series — before Mercedes-Benz built 191,862 examples of the R171 through to a February 2011 close of production.

10 distinct series across 2005–2011 — from the four-cylinder SLK 200 Compressor to the V8-powered SLK 55 AMG, each identified by its chassis, engine and transmission numbers.
