Edmunds' Expert Review
by the Edmunds Experts
Pros
- Compelling engines, versatile retractable hardtop, sharp handling, Airscarf heater.
Cons
- Pricey, substantial blind spots and high beltline, steering lacks feel.
What’s new
The Mercedes-Benz SLK carries over mostly unchanged for 2010. A very-low-production Diamond White Edition SLK300 is now available.
Edmunds says
While convertibles bearing the Mercedes-Benz name have always offered luxury, solidity and brand cachet, the 2010 Mercedes-Benz SLK-Class does them one better -- it's a genuine driver's car.

Vehicle overview
Since being introduced in the 1990s, the Mercedes-Benz SLK-Class has been best known for one thing: its retractable hardtop convertible roof. A revolutionary piece of automotive engineering at the time, it has since spread to other convertibles. Yet the 2010 Mercedes SLK-Class remains an appealing luxury roadster, especially given how much emotion plays on this sort of vehicle purchase. The current (second-generation) SLK may be getting on in years, but it's still an attractive little convertible that looks fresh.
The SLK has an impressive dynamic résumé as well. Unlike past Mercedes convertibles and roadsters, this SLK is actually quite fun to drive, with adept handling that doesn't impose on ride comfort. While it will never match the handling thrills of the superb Porsche Boxster, the SLK stays true to what a roadster should be like to drive. Backing up the driving enjoyment are your choice of two V6 engines or a mighty V8 that adds a whole new level to the car's character.
However, we would be remiss if we didn't mention the fully redesigned BMW Z4, which now utilizes the same grand-touring formula. The new Z4 has not only a retractable hardtop that provides better top-up visibility than the SLK, but also a better-sorted ride, more interior space, a more modern electronics interface and -- in twin-turbocharged trim -- more muscle than the SLK300 and SLK350 can muster.
But the BMW has nothing to match the mighty SLK55's hand-built V8, and there's always the matter of what tugs at your emotional heartstrings. Overall, the 2010 Mercedes-Benz SLK-Class remains an excellent choice for those looking for a premium roadster with grand-touring leanings.
Performance & mpg
The rear-wheel-drive 2010 Mercedes-Benz SLK300 is powered by a 3.0-liter V6 that produces 228 horsepower and 221 pound-feet of torque. A six-speed manual transmission is standard and a seven-speed automatic is optional. Mercedes estimates a 0-60-mph time of 6.1 seconds. EPA estimated fuel economy is 19 mpg city/26 mpg highway and 21 mpg combined with the automatic, and 18/26/20 with the manual.
The SLK350 gets a 3.5-liter V6 that produces 300 hp and 265 lb-ft of torque. A seven-speed automatic is the only available transmission. Mercedes estimates a 5.4-second 0-60 time. EPA-estimated fuel economy is 18/25/20 mpg.
The SLK55 AMG features a 5.4-liter V8 that pumps out 355 hp and 376 lb-ft of torque. An AMG-tuned seven-speed automatic is standard. In Edmunds testing, the SLK55 went from zero to 60 mph in 4.9 seconds. Fuel economy estimates are 14/22/17 mpg.
Safety
Safety equipment includes antilock brakes, stability and traction control, knee airbags and side airbags that cover the head and thorax. The "mbrace" emergency telematics system is also standard. In Edmunds brake testing, the SLK55 came to a stop from 60 mph in a short 115 feet.
Driving
The 2010 Mercedes-Benz SLK-Class's acceleration is strong even in the base V6 model, which is the only SLK to offer a manual transmission; the SLK350 is stronger still but automatic-only. The SLK's handling capabilities will put a smile on just about any driving enthusiast's face, while the ride quality remains comfortable and compliant enough to appeal to the average driver. Only in direct comparison with pure sports cars like the Boxster do the SLK's relatively uncommunicative steering and less tossable nature become apparent.
Even so, the SLK55 AMG will be hard for car lovers to pass up -- it's almost a modern-day Shelby Cobra, albeit with a thick layer of luxury slathered on top. The formula is virtually the same: Start with a capable compact roadster, stuff it to the gills with a giant V8, sharpen the suspension and proceed to stun people at traffic lights when you tear off down the road in a cloud of tire smoke. Handling is also improved thanks to its myriad AMG upgrades. The aging automatic transmission leaves much to be desired, however, as it is slow to respond and doesn't blip the throttle on manual downshifts. Indeed, this is an issue with lesser SLKs as well.
Interior
With its retractable hardtop in place, the 2010 Mercedes-Benz SLK-Class is virtually indistinguishable from a conventional two-seat coupe. Leg- and headroom are acceptable even for tall drivers, though the new Z4 is still roomier inside. The only notable drawback involves the SLK's inferior sight lines, as the intricately constructed roof creates significant blind spots. Press the button to lower the top, though, and all will be forgiven, as al fresco motoring is just 22 seconds away. When lowered, the folded top naturally eats up trunk space, but a modest 6.5 cubic feet is still available.
Interior construction isn't quite up to the level of Benz's latest models, but still, you're unlikely to feel cheated by the SLK. The seats don't look like much, but they somehow manage to provide exemplary support and adequate long distance comfort. We highly recommend opting for the Airscarf system, which breathes warm air on your neck -- it sounds weird but it works. Add to that heated seats, a smart heating system and perhaps a warm hat, and all-season top-down motoring is easily accomplished.
2010 Mercedes-Benz SLK-Class models
The 2010 Mercedes-Benz SLK-Class is a two-seat retractable-hardtop roadster offered in three versions: SLK300, SLK350 and SLK55 AMG, each of which comes with a different engine.

The SLK55 AMG adds a beastly V8 and the usual array of AMG-tuned items (V8 engine, brakes, suspension, exhaust, transmission, styling) plus a sport steering wheel, upgraded leather upholstery, heated seats and the Premium I package. The AMG Performance package adds upgraded brakes, a track-calibrated suspension, light-alloy 18-inch wheels, a higher top speed, a performance steering wheel and carbon-fiber interior trim.

2008 Mercedes-Benz SLK-Class SLK350 2dr Convertible (3.5L 6cyl 7A)
I purchased the car because I was tired of looking for "safe" parking for my Porsche Boxster. The hard-top convertible gives me peace-of-mind so I can park on-street. For the first few weeks, I really missed the Porsche. But now I wouldn't go back. After adjusting to the different ride characteristics, I feel it handles as well as the Boxster and is far superior for longer drives. The … AMG sport package is a must if you want a sports car experience. I've owned MG's, Triumphs, 240Z, 260Z, Porsche 911 Carrerra, Porsche 944 and Porsche Boxster (yes, I'm now an old guy.) This car is as much fun as any of my past cars, and as fast as anything I've driven.
Great around town

2009 Mercedes-Benz SLK-Class SLK350 2dr Convertible (3.5L 6cyl 7A)
This is a great car to drive! For around town driving, it has the right compromise between comfort and performance. It's soft enough so that it is comfortable on the bump and pot hole ridden streets around where I live. However, when on twisty roads in the country, it performs wonderfully at any speed you would drive on public roads. The 300 HP 3.5L V6 gives this car impressive … straight line performance. It's definitely not a Porsche, but it's not supposed to be... The retractable hard top is wonderful considering the amount of rain we get. Build quality is excellent - no squeaks or rattles to speak of and no other problems / issues after 1 year of ownership.
A true sleeper which should get more respect

2008 Mercedes-Benz SLK-Class SLK55 AMG 2dr Convertible (5.4L 8cyl 7A)
I am amazed at how inexpensive this car is on the used market. It is a true supercar at the price of a Miata! Incredible handling, killer looks, awesome straight line acceleration, stop on a dime brakes, and way better than advertised fuel economy. Loving every minute.
The Perfect Machine

2008 Mercedes-Benz SLK-Class SLK280 2dr Convertible (3.0L 6cyl 6M)
The lease was up on my 2006 E350 so I jumped into a 2008 SLK 280. The E350 is flawless but I needed more of a "wow" factor. The black exterior with the tan and black interior is stunning. This car is the perfect blend of performance and luxury. My SLK has Premium III (navigation) with the appearance package. The retractable hardtop is provides the "wow" factor. The fun of driving a … convertible without the downside of a ragtop. My only other convertable was a 2003 Z4. The SLK provides more convenience, safety and luxury than the Z4. Remember, it's not how fast you go, it's how well you go fast.
