The SLK retractable hardtop roadster was redesigned in 2006 with styling cues inspired by the SL roadster. It returns for 2008 in three basic forms. The SLK280 is powered by a 228-horsepower, 3.0-liter V-6 engine. The SLK350 features a 268-hp, 3.5-liter V-6 engine. High-performance enthusiasts can select the SLK55 AMG and its 355 hp engine for ultimate power.
Transmission choices include a six-speed-manual and a seven-speed-automatic gearbox with TouchShift operation. The SLK rides on 17-inch alloy wheels and performance tires; a lowered sport suspension is offered for more aggressive driving.
A special version of the SLK350, the Ten Year Anniversary edition, gets an automatic gearbox, 17-inch wheels, special badging, and red stitching and trim on the interior.
The SLK's interior is adorned with silver trim and switchgear, with a dashboard that flows into the door panels and an instrument panel that sports large, chronograph-style gauges. Its power retractable hardtop can incorporate an optional feature that channels warm air from vents located in the driver and passenger's headrests for open-air use on chillier days.
Standard equipment includes four-wheel disc brakes with anti-lock control, side and knee airbags, and stability control. Power heated seats, a premium Harmon Kardon audio system, and run-flat tires are optional.
