Road Test

The SLK320 provides a quiet and pleasant driving experience. Outward visibility is very good, plus access and trunk capacity are among the best in its class. The SLK also provides a more solid feel, with less body shake than typical convertibles. It handles and accelerates well, but isn't as sporty feeling as some of its competitors. More steering feel would help it tremendously in this area.

Model History

2012-2016

2012 Redesign Year

A 2012 freshening brought a new 3.5-liter V6 and seven-speed automatic, as well as a 1.8-liter turbo four-cylinder with a six-speed manual. The small cabin is well finished, but narrow. On the whole though, we like this car. Handling is sporty and enjoyable, while ride and noise levels are civilized enough to leave you unrattled on a long road trip. The retractable metal top folds away quickly. When it's up, the SLK behaves as a credibly solid and quiet coupe. Safety features include antilock brakes, brake-assist and electronic stability control as standard equipment. The optional "Attention Assist" system warns drivers who show signs of growing tired. Available features for 2016 include optional blind spot monitoring. Additionally, the SLK250 was replaced by the SLK300 for 2016, which brought more power and a nine-speed automatic transmission.

2005-2011

2005 Redesign Year

This two-seat convertible has many high-end technical and safety features, including a power-folding hardtop. With the roof up it feels almost as solid as a fixed-roof coupe. Over the years, the SLK continued to be fun to drive, with agile handling, a comfortable ride, and a strong V6. In fact, this version of the SLK is even more fun to drive than its predecessor. The engine provides strong power and torque and the suspension is fully capable of handling the upgraded performance. Optional warm-air vents in the head restraints add comfort when driving with the top down on cool days. The manual shifter and clutch are a pleasure to use.

1998-2004

1998 Redesign Year

This two-seat convertible was introduced for 1998, boasting many innovative technical and safety features. Its major draw is an electrically-retractable hardtop that folds and stows in the trunk at the touch of a button. With the roof up, this convertible feels almost as solid as a fixed-roof coupe, but, overall, the SLK isn't very sporty. The steering isn't quick or precise, and the supercharged, intercooled 2.3-liter Four lacks oomph. Interior space is tight. Model-line updates include a vague and rubbery five-speed manual transmission for 1999 and the V6-powered, six-speed SLK320 for 2001.
