The Mercedes-Benz CLK-Class is a former series of mid-size or entry-level luxury coupés and convertibles produced by Mercedes-Benz between 1997 and 2010. Although its design and styling was derived from the E-Class, the mechanical underpinnings were based on the smaller C-Class, and was positioned between the Mercedes-Benz SLK-Class and CL-Class.[1]

In 2010, Mercedes moved the CLK-Class designation back to the E-Class, as it had been called previously.[2]

The first-generation W208/C208 CLK was introduced in 1997, and was based on the W202 Mercedes-Benz C-Class launched three years earlier. The W208 coupé was replaced by the W209 CLK-Class in 2002 (for the 2003 model year), although the convertible remained in production until 2003 when replaced by the C209 CLK.

History[edit]

The CLK introduced a new market niche for Mercedes-Benz. Although the W208 used components from the E-Class (W210), aesthetic based on the E-Class and had a specification level higher than the E-Class, it was in fact based on the less expensive C-Class (W202) platform.

Two versions were initially available: the four-cylinder CLK 200 (136 PS (100 kW; 134 bhp)) and four-cylinder supercharged CLK 230 Kompressor 193–197 PS (142–145 kW; 190–194 bhp).

The CLK 320 Coupé was introduced in the 1997 model year, powered by a 218 PS (160 kW; 215 bhp) 3.2 L V6 engine. The CLK GTR FIA GT1 racing car appeared in 1998, powered by a 5.9 L V12 engine; 25 road-going CLK GTRs were made. The CLK 430 Cabriolet and the 279 PS (205 kW; 275 bhp), M113 4.3 L V8-powered CLK430 appeared in 1999. All models were available in both coupé and convertible form. In Europe, the supercharged I-4 powered CLK200 Kompressor was also available, reaching impressive 193 bhp, thanks to euro2 permissive emission specs.

In late 1999 for the 2000 model year, a facelift was launched which incorporated, among others, a revised instrument cluster with a bigger multifunction display, steering wheel with controls for the multifunction display and radio, Tiptronic automatic gearbox, revised bumpers and new side skirts. Wing mirror-mounted turn signals were not implemented until 2001 for the 2002 year model.

In the United States, the CLK430 could be equipped with a "Sport Package," which gave it the external styling of the more powerful CLK55 AMG, and equipped it with the same wheels and tires as its AMG counterpart (see section "CLK55 AMG"). This allowed it to reach up to 0.83G's of lateral acceleration, and 66.5 mph on the slalom run.[3]

The high-performance CLK 55 AMG, which was introduced first in Europe in 2000, was powered by the 347 PS (255 kW; 342 bhp) M113 5.4 L V8 engine; the CLK55 AMG Cabriolet was launched in 2002, the last model year of this body style.

Engine[edit]

The CLK55 AMG is powered by a hand-assembled 5.4-liter V8 engine. The hardware list includes super-stiff forged billet steel crankshaft, forged, weight-matched connecting rods and pistons, lightweight AMG-specific chain-driven single overhead camshafts V8 (one cam per cylinder bank) with two intake and one exhaust valves per cylinder, as well as 8 coil packs and 16 spark plugs (two spark plugs per cylinder). Its bore and stroke are 97 mm × 92 mm. The dual-resonance intake manifold with tuned runners helps create optimized torque and power outputs by taking advantage of two resonant frequencies to increase performance. The engine features a high compression ratio of 10.5:1. All of these advanced technologies help deliver a healthy 342 hp (255 kW) and 376 lb⋅ft (510 N⋅m) of torque.

Transmission[edit]

The five-speed automatic transmission is adapted from the gearbox used in the V-12 S-class models, because that gearbox can take the torque. It is fully adaptive and electronically controlled, and is a stronger unit than that of the CLK430. Also a larger four-bolt driveshaft that's four inches in diameter connects to a reinforced rear differential to keep all the extra power under control. Standard traction control keeps wheelspin to a minimum, while its Electronic Stability Program (ESP) keeps the CLK on its intended path.

Handling[edit]

The standard CLK chassis is used, and while the current version is not based on the new C-Class platform, the AMG version of the CLK offers some special undercarriage components. The four-wheel independent suspension is basically the same as the lesser CLK versions, but AMG fits higher-rated springs, tighter shock valving, larger diameter anti-roll bars and stiffer suspension bushings. The resulting firmer, more controlled ride is made even tighter by its high-performance ZR-rated low-profile tires. The brakes have been enhanced as well. The huge four-wheel discs are larger and thicker than the other CLKs, and the rear discs are specially vented to enhance cooling. An anti-lock braking system (ABS) is standard, while Brake Assist applies full braking force in panic stop faster than a driver could. It rides on AMG Monoblock alloy wheels, 7.5" front and 8.5" rear, shod with 225/45ZR17 and 245/40ZR17 Michelin Pilot Sport tires.

CLK GTR[edit]

The Mercedes-Benz CLK-GTR was a V12 mid-engine race car developed for the 1997 FIA GT Championship. It shared only the instrumentation, front grille and the four headlamps with the normal CLK C208. Production of the required 25 road cars began in winter of 1998 and finished in the summer of 1999.

F1 safety car[edit]

A specially modified version of the CLK55 AMG was used during the 1997 F1 season as a safety car.[4]

Second generation (C209/A209; 2002–2009)[edit]

C209 CLK-Class

The Mercedes-Benz C209/A209 is the second generation CLK-Class, and was launched in 2002 with production starting in June.[5] The car was available in both hardtop coupé (C209) and in soft-top convertible form (A209), with a choice of petrol and diesel engines. At introduction, a 3.2-litre V6, 5.0-litre V8, 5.4-litre V8, and 2.7L inline-5 diesel engine was available.[6] In 2010, the CLK lineup was discontinued and replaced by the C207 E-Class coupé and A207 E-Class convertible.[7]

Successor (C207/A207; 2010–2017)[edit]

C207 E-Class

The C207/A207 E-Class was introduced as part of the new fourth-generation E-Class lineup, and was first shown at the 2009 Geneva Motor Show.[8] It is based on the W204 C-Class platform,[9] but shares 60% of its parts with the E-Class sedan and wagon.[10] In 2013, the C207/A207 received a facelift, featuring updated design changes and performance and fuel economy improvements.[11]
