Mercedes-Benz SLK-Class Review

The 2015 Mercedes-Benz SLK-Class ranks 10 out of 16 Luxury Sports Cars. This ranking is based on our analysis of published reviews and test drives of the Mercedes-Benz SLK-Class, as well as reliability and safety data.

The 2015 Mercedes-Benz SLK-Class is ranked:

The 2015 Mercedes-Benz SLK-Class has a handsome interior and a good mix of agile handling and ride comfort, according to auto writers, but it isn't as quick or athletic as some rivals.

The 2015 SLK250 is powered by a turbocharged four-cylinder engine that critics think has sufficient power, but delivers unimpressive acceleration for a sports car. They say the V6-powered SLK350 feels noticeably more powerful and that the V8-powered SLK55 AMG has thrilling acceleration and is engaging to drive. The SLK250 comes standard with a six-speed manual transmission, while all other models come standard with a seven-speed automatic. The SLK250 is available with the automatic as well. Test drivers report that the SLK-Class' automatic transmission doesn't shift as readily as rivals' transmissions. According to the EPA, the SLK250 earns 22/32 mpg city/highway, which is good for the class. Reviewers note that the 2015 SLK-Class has nimble handling, precise steering and a comfortable ride, but that some rivals offer a much more exhilarating driving experience.

Automotive journalists agree that the 2015 Mercedes-Benz SLK-Class has a top-notch interior, with remarkable material quality and a stylish design. They say the seats are comfortable to sit in, but that the cabin feels small and somewhat cramped. Trunk space is good for the class. Standard features include Bluetooth, HD Radio and a panoramic roof panel in the retractable hardtop. Available features include dual-zone automatic climate control, satellite radio, an 11-speaker Harman Kardon surround-sound stereo system, Mercedes' COMAND infotainment system with a 7-inch display, navigation, blind spot monitoring, lane departure warning, parallel park assist, forward collision warning with automatic braking, adaptive cruise control and a Magic Sky Control roof panel, which adjusts the transparency of the panel to let in more or less sunlight. Auto writers say the SLK-Class' infotainment system is simple to use after some practice.

  • "Now in its third generation, the latest SLK provides a much better balance between handling and comfort while continuing to offer the versatile hardtop convertible configuration that made the original a hit." -- Left Lane News
  • "The compact 2015 Mercedes-Benz SLK-Class is a standout luxury convertible that offers retractable-hardtop convenience and rewarding performance in a dignified package." -- Edmunds
  • "Think of the 2015 Mercedes-Benz SLK as two cars in one: a fun-loving open-air roadster and a cozy, secure coupe. The dual personality comes courtesy of a hardtop roof that retracts with the touch of a button. As with its main competitor the BMW Z4, this ability to transform gives this small 2-seater a degree more practicality. Mercedes' compact convertible touts a plusher ride compared to its more dynamic BMW rival yet still offers a good blend of power and handling." -- Kelley Blue Book
  • "In other respects, the SLK is the consummate luxury hardtop convertible, as long as you don't mind driving a pint-sized car instead of something like the relatively imposing SL. Indeed, that's the only real compromise the SLK demands. If you're looking for a small roadster with a grand-touring pedigree, the SLK is hard to beat." -- AutoTrader (2014)

Test drivers note that the Chevrolet Corvette's standard V8 engine is extremely powerful and delivers blistering acceleration. They add that the Corvette has agile handling, a comfortable ride and excellent cargo space for a sports car.
