Chronology
PredecessorMercedes-Benz R170

R171 represents the second generation of Mercedes-Benz SLK. Compared with the R170, R171 has larger dimensions.

The Mercedes-Benz SLK-Class is a luxury roadster built by the German manufacturer Mercedes-Benz since 1997. The name was chosen to reflect the company's intentions for the car - that it be Sportlich (sporty), Leicht (light), and Kurz (short). There have been two generations of SLK cars from Mercedes-Benz.

Like its predecessor, the second generation of the vehicle featured a retractable hardtop. Following the trend initiated by the R170 model, by the time the R171 was released, this had become an increasingly common feature in almost every new convertible introduced in the market, especially in Europe.

The SLK was updated in 2004 with a new Formula One-inspired appearance and serious performance; the new model also took design cues from the Mercedes-Benz Vision SLA concept car, presented in 2000. The new R171-platform SLK was again on Car and Driver's Ten Best list for 2005, and it won the Canadian Car of the Year Best New Convertible award. Highlighting its potential appeal to women, New Zealand's Lucire magazine announced it as its 'Car to Be Seen in' for 2005. The current SLK is built in Bremen, Germany.

2008 Facelift

A facelift of the R171, with more powerful engines and an updated front splitter was unveiled at the end of 2007. The SLK 200 now produces 184 hp while the SLK 350 is upgraded to produce 305 hp. The SLK 280 and SL 55 AMG engines remain unchanged.

Unverified rumours

According to Automobile Magazine, based in Ann Arbor, Michigan, a hatchback-coupe version should be available in 2009, possibly with an SLK63 AMG variant with the new 6.2L (advertised as 6.3 by Mercedes-Benz) DOHC V8 made by AMG.

This date has now been pushed back to 2010 or 2011. Also, more engine options have been opened up, a small diesel, as well as a turbo six-cylinder have been considered for the R172.
