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 hp 2.3 L supercharged I4 engine and automatic transmission. The SLK was on Car and Driver’s Ten Best list for 1997.

An AMG model was added in 2001, with a 354 hp (264 kW) supercharged 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 M Roadster and Porsche Boxster S. It was only offered with automatic transmission and was hand built.

Not all Mercedes SLKs were built in Bremen, 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.
