The Mercedes-Benz SLK is a compact executive roadster, produced by Mercedes-Benz. It was released in 1996 and was built at the Mercedes plant in Bremen, Germany, until the end of production in 2020. With the release of the facelift R172 in 2016, the SLK-Class was renamed to SLC-Class in accordance with the revised nomenclature adopted by Mercedes. Under this scheme, roadsters use the base name "SL", followed by the model's placement in the Mercedes-Benz hierarchy, the letter "C", being the roadster equivalent to the C-Class.

History of the Mercedes-Benz SLK

First Generation Mercedes-Benz SLK (R170; 1996–2004)

The R170 Mercedes SLK was the first generation compact roadster produced by Mercedes-Benz, from 1996 to 2004. It was designed in late 1991 under Bruno Sacco, with a final design being completed in early 1993 and approved by the board, with a German design patent filed on September 30, 1993. The production SLK-Class was introduced at the Turin Motor Show on 22 April 1996, appearing as a modern incarnation of the 1950s Mercedes-Benz 190SL, by returning to four cylinders and with an identical 94-inch (2,400 mm) wheelbase. A facelift was introduced to all models in 2000, featuring an updated design and updated engines.

Second Generation Mercedes-Benz SLK (R171; 2004–2010)

The R171 SLK was unveiled at the 2004 Geneva Motor Show. It features increased use of high-strength steel, and improvements to the car's torsional strength and aerodynamic efficiency. Models feature a more compact, revised roof mechanism that is operated in 22 seconds (previously 25 seconds), resulting in an increase in boot capacity by 63 liters (2.2 cu ft). The R171 also introduced the Airscarf system that integrates the neck-level heating system into the headrests of the car. The front-end design of the car was inspired by the noses found in Formula One cars. It was facelifted in 2008 and featured new engines and minor exterior design changes.

Third Generation Mercedes-Benz SLK (R172; 2011–2020)

The R172 SLK was released in 2011. It was available with a range of inline-four, V6, and V8, diesel and petrol engines, and introduced an electronically operated window tint shade for the sunroof, called Magic Sky Control. The facelift was released for vehicles produced from March 2016, to coincide with the 20th anniversary of the SLK-Class. The model range was also renamed to SLC-Class to conform to the new Mercedes nomenclature and introduced new engines and a revised design. In 2020, Mercedes-Benz released a Final Edition to commemorate the end of the car's production run.


In 2016, Mercedes-Benz retailed the Mercedes-Benz SLK with an original MSRP of $47,925, which is around $59,507 in 2022.

Features of the Mercedes-Benz SLK

Exterior Features

When it was unveiled, it was a shock: it resembled the same year Mercedes-Benz SL model, just smaller. The new headlights swept back over the fenders and the wide trapezoidal grille were inspired by its bigger brother. The big, three-pointed star badge was accompanied by two silver wings. On the apron, there was another grille to cool the engine and two side scoops to cool the brakes and host the daytime running lights. On the front fenders, the designers placed extracting vents. Behind the passengers, there were two security arches.

Interior Features

Inside, the car was fitted with two bucket-seats with incorporated seatbelts. The three-spoke steering wheel inspired a sporty sensation and it wasn't the only specific item. The air-vents were surrounded by chromed rings. A screen for the infotainment unit was placed on top of the center stack, at the same level as the steering wheel.
