The SLK is a compact Roadster manufactured by Mercedes-Benz in two generations, R170 and R171, since 1997.

As one of the first modern Retractable hardtop convertibles, the SLK followed the 1995 Mitsubishi 3000GT and preceded other retractable hardtops such as the Peugeot 206, Lexus SC, Mercedes-Benz SL-Class and the Chrysler Sebring.

The designation SLK derives from the company's design mission to create a roadster that was at once sporty, light and short — in German: Sportlich, Leicht und Kurz. [1]

The term SLK-Class is a Mercedes marketing term referring to the vehicle in all its engine configurations across both design generations.

Competitors include the Audi TT, BMW Z4, Lexus SC, Porsche Boxster, and Porsche Cayman.

R170 (1997- 2004)


1997-2000 Mercedes-Benz SLK
Main article: Mercedes-Benz R170


The R170-platform SLK 230 Kompressor was introduced in 1997 for model year 1998 to compete with the Porsche Boxster and BMW Z3. Setting it apart was its folding hardtop, though its additional weight compromised the performance of the 185 Horsepower 2.3 Liter Supercharged Straight-4 Internal combustion engine and Automatic transmission. The SLK was on Car and Driver's Car and Driver Ten Best for 1997.

A 5-speed Manual transmission was added for 1999 along with the 215 hp 3.2 L V6 and 6-speed manual transmission in the 2001 SLK 320.

An AMG model was added in 2001, with a 354 hp (264 kW) Supercharger version of the 3.2 L V6. This SLK 32 AMG was the best-performing R170 SLK, and was a direct rival of the BMW Z3 and Porsche Boxster S. It was only offered with Automatic transmission and was hand built.

Not all Mercedes SLKs were built in Bremen (city), Germany, the SLK 320 being built in South Africa and Mexico. The very first R170 Mercedes SLK was completed on January 29, 1997 and last on April 7, 2004.
