Mercedes-Benz Mercedes SLK 1996-2004 Specifications

The 1996-2004 Mercedes SLK offered three main engine options: the 2.0L inline-4 (SLK200), the 2.3L supercharged inline-4 (SLK230 Kompressor), and the 3.2L V6 (SLK320). The SLK200 produces 136 hp, the SLK230 Kompressor delivers 192 hp with enhanced torque, and the SLK320 offers 218 hp, providing a balance of power and smooth performance. The SLK230 and SLK320 are better suited for spirited driving due to their higher power output and torque.

The SLK came with a 5-speed manual transmission as standard, with an optional 5-speed automatic transmission (4-speed for earlier models). The automatic transmission featured adaptive shift logic for smoother gear changes and improved performance.

The SLK included standard safety features such as dual front airbags, ABS, and stability control (ESP). Optional features included side airbags and a roll-over protection system (ROPS) that automatically deployed in the event of a rollover.

The SLK200 achieves approximately 24 mpg city and 32 mpg highway, while the SLK230 and SLK320 average around 21 mpg city and 28 mpg highway. These figures are competitive with other luxury roadsters of the era, such as the BMW Z3 and Porsche Boxster.

Mercedes recommends oil changes every 10,000 miles or annually, whichever comes first. Other maintenance tasks include brake fluid replacement every 2 years, spark plug replacement every 60,000 miles, and timing belt inspection/replacement as per the service manual.

The SLK featured a retractable hardtop, leather upholstery, automatic climate control, and a premium sound system. Optional upgrades included heated seats, navigation, and a sport suspension package.

The SLK offers 9.6 cubic feet of trunk space with the roof up, which is slightly less than the BMW Z3 but comparable to the Porsche Boxster. Passenger space is snug, with limited legroom for taller drivers.

The SLK is not designed for towing. Its payload capacity is approximately 800 lbs, including passengers and cargo.
