The Mercedes-Benz C209/A209 cars have been produced from 2003 to 2009. They are sold under the CLK-Class model names. The C209/A209 is based on the W203 C-Class. It replaced the C208 CLK-Class after 2003 which were the first car to carry the CLK moniker.
The C209/A209 is available in two body styles, a coupe (C209) and a cabriolet (A209), and is manufactured with diesel and petrol engines ranging from four-cylinder (CLK200) to eight-cylinder (CLK500 and CLK63AMG). The cabriolet (Designated with an A, as in CLK500A) features a fully automatic retractable soft top covered by a metal tonneau that can be raised and lowered from outside the vehicle using the key fob.
A CLK AMG DTM was produced as a MY2006 in both a coupe and later cabriolet model. Styling cues were taken from the C-Class race car used for the German Deutsche Tourenwagen Masters racing series. The car includes a wider body, rear wing spoiler, carbon fiber accents, and upgraded suspension.
Market position and competitors 
The CLK is designed to fill the mid-luxury market position for coupes and convertibles. It is Mercedes-Benz’s only 4-seat cabriolet. Its direct competitors in the cabriolet market are the Volvo C70 and the Lexus SC430, although it is available with larger engines than any of its direct competitors. The CLK is positioned midway between the BMW 3 series coupe/cabriolet and the BMW 6 series coupe/cabriolet.
Performance is electronically limited to 135 mph (217 km/h) in the CLK350 model, and to 155 mph (249 km/h) in the CLK500 and CLK55 models. An AMG factory option is available for an unrestricted top speed.
The Electronic Stability Control (ESP) and Anti-lock braking system (ABS) are both aids to handling, making such feats as a 90’ degree turn on a typical two lane intersection from 50 mph (80 km/h) possible using simple hard braking and turning with no significant fishtailing. The ESP system cannot be turned off - it makes intentional high-power fishtailing impossible without using a factory test protocol that end-users generally cannot enable.
Each model seats four and in the US this includes an all-leather interior with burl walnut trim. For Europe the models are available as "Elegance" and "Avantgarde" essentially, basically 'Luxury' or 'Attitude' specification where the Elegance uses Burr Walnut trim and polished alloy wheels and the Avantgarde uses alloy trim and chunkier wheels. Also there is the Sport upgrade package for the Avantgarde, with 18" Alloys and an interior upgrade. Finally there is also the "Sport" (UK only) - an 'AMG' version from factory for the 280 V6 petrol, 220 4 cyl diesel and the 320 V6 diesel (though not an AMG engine) trimmed (including 18" AMG alloys and wider rear track, suspension set-up, sport/tiptronic/manual gear options, body styling, paddle shifts, sports exhausts, etc.) and made available from 2005/06. The price and specification for European models is otherwise the same. The 4 cyl. cars wear 16" wheels, while the CLK320, CLK350 and CLK500 come with 17 inch (432 mm) alloy wheels, the CLK55 AMG sports 18" (457 mm). The cabriolets have a remote-operated automatic soft-top and sensor-controlled roll bars. Since its introduction, all US cars come standard with a Tele Aid emergency assistance system, automatic dual-zone air conditioning, 10-way power front seats and rain-sensing windshield wipers. Seven-channel digital surround sound comes standard. A Keyless Go system, navigation system, Parktronic system, and bi-xenon HID headlamps are all available as options. All models come with four side airbags. European cars differ considerably and are usually specced depending on the buyer's needs.
The cars have a manual sport/comfort mode switch that sets the automatic transmission to start in 2nd gear and shift earlier in comfort mode. With the new 7-speed transmission, the car is about 20% more fuel-efficient compared to the 5-speed, with no loss of performance. In the CLK500, at 80 mph (130 km/h), the 5-speed transmission runs at about 3000 rpm, while the 7-speed runs at about 2200 rpm. In the AMG model, the transmission can be set to remain longer in lower gears for higher performance.
The 5-speed CLK500 gets an average of 15mpg in city driving conditions, whereas the 7-speed CLK550 get an average of about 18mpg under the same conditions. Both add about 3mpg for highway driving.
The C209/A209 CLK-Class is 2.4 inches (61 mm) longer, 0.7 inches (18 mm) wider and 1.1 inch (28 mm) higher than its predecessor.

Black Series 
The CLK 63 AMG Black Series produced from 2007 to 2009 is slightly heavier than the car on which it is based, but is significantly faster thanks to an updated differential, power-tuned engine, and various other tweaks. The CLK 63 AMG reaches 60 mph (97 km/h) in 4.3 and 100 mph (161 km/h) in 9.3 seconds, while the CLK63 AMG Black Series takes just 4.0 to 60 mph (97 km/h), and 100 mph (161 km/h) takes just 8.8. In this Black Series model the rear seats have been removed, so this is a two-seater only. The Black Series Cost £100.000 (£34,000 more than the standard CLK63 AMG). However, thanks to power tweaks it can now reach, but is limited to, 186 mph. The engine is a 6.2L AMG V8 which produces 507 bhp and 465 lb.ft of torque.

Comfort and convenience 
Mercedes-Benz concentrates its ergonomic design engineering efforts on subtle luxuries, such as seat-belt presenters, automatically lowering headrests when the seat is moved back so that it’s in the correct position for tall drivers, and lowering the passenger side mirror to show the curb when the car is in reverse.
More obvious conveniences include automatically dimming mirrors, in-dash navigation instructions, steering wheel control of audio system, iPod, and integrated telephone system, and cornering fog lamps that illuminate the road when you turn in the same direction as the turn indicators signal.
Model changes 
The C209/A209 was introduced in 2002. At introduction, it was available with a 3.2-liter engine, a 5.0-liter engine, and a 5.5-liter engine. The 2004 CLK was the last Mercedes Benz automobile to use the venerable D2B (Digital Data Bus) optical fiber media system introduced a decade earlier. The most obvious problem with this system was the clearly obsolete CD-ROM based navigation system.
The 2005 update included the MOST (Media Oriented Serial Transport) media system used in the rest of the Mercedes Benz line, bringing along a significantly upgrade DVD based navigation system and iPod integration as optional features. The 2006 included an improved 3.5-liter 6-cylinder engine and added the steering wheel shift paddles from the AMG model to the CLK500.
In 2009, the CLK was discontinued, the replacement being the E-Class Coupe and Convertible.
- The CLK 63 AMG was used as the Safety Car in the 2006 and 2007 Formula One World Championships, replacing the previously used SLK 55 AMG.
