2006 Mercedes-Benz CLK-Class Review

A good blend of style and performance for drivers with a bigger budget.

Reviewed by Automotive on


The 2006 Mercedes-Benz CLK-Class falls nicely between the sportier SLK and the larger CL, offering a blend of comfort and performance that any driver will enjoy. With its sleek body and convertible option, the 2006 CLK proves great for weekend cruising and adventurous driving, while its comfortable interior and full range of high-tech features also suit it well to luxury commuting.

The Mercedes-Benz CLK-Class received a total makeover in 2003, and this luxury coupe has only improved its design in the years since. The two-door, four-passenger CLK is manifested as a luxury sport coupe, a luxury convertible, and a convertible sports car. Its five trim levels range from the basic CLK350 coupe to the athletic CLK55 AMG Cabriolet.

For 2006, Mercedes-Benz reintroduces the old CLK320 as the CLK350, dressing it up with a new engine, wheels, and an upgraded transmission. The CLK500 benefits from a refreshed interior, while all CLK models receive a handful of minor improvements.

The Range

Body styles: two-door sport coupe, luxury convertible, convertible sport coupe
Engines: 3.5-liter V-6 (CLK350), 5.0-liter V-8 (CLK500), 5.4-liter V-8 (CLK55 AMG)
Transmissions: seven-speed automatic (CLK350 and CLK500), five-speed automatic (CLK55 AMG)
Models: CLK350 coupe, CLK500 coupe, CLK350 convertible, CLK500 convertible, CLK55 AMG convertible

What's New

2006 brings only a few small changes to the full 2006 CLK-Class lineup, with all trim levels now offering active head restraints, along with a new grille and taillights. Additionally, the CLK500 now boasts a sportier interior to match its power under the hood.

Most notably, the old Mercedes CLK320 is remade for 2006 as the CLK350. This updated model sits on 17-inch alloy wheels powered through a seven-speed automatic transmission. The CLK350 also gets a more powerful 3.5-liter V-6 engine.


The CLK-class’s 2003 full reworking brought a sleeker appearance to the coupe’s relatively boxy former design. This sporty car has a classier personality with its SL-inspired silhouette. As a hardtop convertible, the 2006 CLK stands apart from its competitors. The hardtop also eliminates the need for a pillar between the front and rear side windows, allowing for a more streamlined look and ride with the top down. Mercedes-Benz offers a full spectrum of exterior paint colors, along with a choice of three convertible roof colors, allowing buyers to match the CLK to their own style.


The 2006 CLK-Class offers an abundance of interior luxuries and high-tech features to make the ride as enjoyable as possible. An easy entry system powers the front seats up and down, making it easier to climb in and out of the back seats. And while many two-door cars suffer from the problem of hard-to-reach seatbelts in the front seats, the CLK-Class provides a solution with automatic seatbelt “presenters” that slide the belts forward when the doors close. In the CLK coupe models, the rear seats fold completely flat to create more cargo space. The convertible’s top conveniently rises and lowers with the press of a button on the key fob, while a narrow roof design and larger side windows allow for better visibility with the top up.

All 2006 CLK models feature fine leather upholstery. Other standard features include power front seats, dual-zone climate control, and a 10-speaker Harman Kardon sound system. Optional accessories include a DVD navigation system, satellite radio, rear parking sensors, adaptive cruise control, and Keyless Go, which allows you to start the engine without a key.

Performance & Handling

The CLK350 houses a V-6 engine capable of pushing 268 horsepower, while the CLK500 runs on a 302-hp V-8. A seven-speed automatic transmission with overdrive comes standard on both models. Drivers looking for a sportier engine might prefer the CLK55 AMG Cabriolet, which comes equipped with a 5.5-liter V-8 and 362 horsepower.

The CLK-Class does not offer as much athleticism as the two-seat SLK, although it is more agile than the bigger-bodied CL-Class. The CLK’s powerful engines allow for sturdy handling and strong acceleration. Everyday drivers will be more than pleased with the 2006 CLK-Class’s luxury blend of sportiness, style, and practicality.


The 2006 CLK-Class offers the standard collection of Mercedes-Benz safety features, including stability control, traction control, front and rear head airbags, dual front side-mounted airbags, four-wheel anti-lock disc brakes, and emergency braking assist. Additional standard features include child seat anchors, a remote anti-theft alarm system, and seat belt pre-tensioners. The convertible models offer dual front airbags with head protection chambers.
