2010 Mercedes-Benz SLK Class

SLK Transforms from a Quiet Coupe to Topless Roadster in 22 Seconds

Mercedes-Benz is debuting a limited-production SLK300 Diamond White edition for the 2010 model year. This special-edition SLK coupe/roadster features Diamond White metallic paint and a two-tone interior with high-contrast 'baseball' upholstery stitching. Fewer than 100 of the SLK Diamond White editions will be offered in the Ú.S., and its impressive array of special standard equipment includes sport suspension, steering-wheel shift paddles and 18-inch AMG alloy wheels.

The 2010 SLK line includes three distinct models – the SLK300, powered by a 228-horsepower 3.0-liter V6; the SLK350, with a 300-hp version of the popular 3.5-liter V6; and the high-performance SLK55 AMG, fitted with a 355-hp AMG V8. All 2010 models come with a steering wheel covered in premium leather and a new monitoring system showing individual tire pressures. For 2010, all SLK300s (except the Diamond White edition) are fitted with new 17-inch twin- five-spoke alloy wheels.

Direct-Steer System

All three SLK models boast athletic performance, thanks in part to an innovative Direct-Steer system. Variable-ratio rack gearing provides impressive on-center steering feel with even higher responsiveness beyond the first five degrees of steering angle. Purely a mechanical system, Direct Steer minimizes steering input during cornering and in low-speed maneuvers such as parking.

SLK350 Engine Boasts 300 Horsepower

With a higher-revving, 7,200-rpm redline, the SLK350 engine features more horsepower and torque, thanks to its larger displacement as well as specially shaped pistons that produce a higher 11.7-to-1 compression ratio, a modified camshaft for higher valve lift, heavy-duty conical valve springs and lightweight valves made of high-temperature steel as well as sodium-cooled exhaust valves. To counteract high-speed camshaft chain vibration, the higher-revving SLK350 Sport engine comes with tri-oval chain sprockets. Above 6,300 rpm, the tri-oval sprockets generate inversely phased pulses that tend to neutralize the usual vibration. For maximum air flow at high rpm, the Sport engine also makes use of a single-stage intake manifold, and valve timing has been advanced slightly to preserve its broad power range.

The SLK-Class can be ordered with a Sport package that includes AMG body styling, sport suspension, steering-wheel gearshift paddles and 18-inch AMG wheels. The Sport package includes AMG's automatic 'rev-matching' feature for virtually jolt-free downshifting, which reduces load-change handling response, and for motorsports-minded drivers, improves braking before turn-in.

Coupe to Topless Roadster in Only 22 Seconds


With the first retractable hardtop in modern times, the SLK started an industry trend toward hardtop convertibles that's still going strong. After shaking up the small roadster market when it was introduced more than a decade ago, the second-generation SLK wowed the public again when it hit Ú.S. streets in 2004.

The retractable hardtop of the SLK sets it apart from the competition. With the top up, it's a quiet coupe – push a button, and the car goes topless. The SLK roof goes up or down in 22 seconds, and the folded roof takes up surprisingly little trunk space – thanks to its pivoting rear window. Like the retractable hardtop of the larger SL model, the rear window of the latest SLK swivels to match the curvature of the top, providing nearly three more cubic feet of trunk room than its predecessor.

Styling Influenced by the World of Formula 1 Racing


With freshened styling for 2009, the latest SLK line boasts a front design with a strong influence from the world of Formula 1 racing, a rear apron incorporating an air diffuser and trapezoidal exhaust outlets. Inside, all SLKs showcase chronometer-type gauges with aluminum accents, a three-spoke sport steering wheel and an audio system with an in-dash six-disc CD / DVD changer as well as a Bluetooth interface that allows a cellular phone still in a pocket or purse to be operated through the car's audio system.

The SLK is available with an optional multimedia package that includes a harmon/kardon premium audio system, HD radio, SIRIÚS-XM satellite radio, GPS navigation with a larger display, a voice control system, an SD memory card slot and a hard drive for storing music and GPS navigation maps.

One of the Safest Open Cars

Like all Mercedes-Benz passenger vehicles, the SLK comes equipped with ESP stability control, a Mercedes innovation that can help prevent slides and spins, especially in slippery weather. ESP can detect an impending spin or slide and prevent it by applying the brakes to individual wheels or reducing engine power. In addition, traction control helps to provide safer travel on slippery roads.

The SLK's unibody uses an impressive amount of high-strength steel alloy – 42 percent of the total structure – and the entire body shell is zinc-coated for long-term corrosion protection. The SLK also makes use of a scratch-resistant clearcoat paint that was developed in the nano-technology sector.

AIRSCARF for an Extended Driving Season

An optional AIRSCARF system can extend the open-air driving season into the cooler months. Built into the seatbacks of the SLK, the neck-level heating system blows warm air from the driver and passenger-seat head restraints, allowing occupants to cruise comfortably with the retractable hardtop open in cooler weather. AIRSCARF even compensates automatically for changes in vehicle speed.
