Mercedes-Benz CLK DTM AMG: The Touring Car Terror
In 2003, Mercedes-Benz factory driver Bernd Schneider achieved a monumental victory, securing the fiercely competitive Deutsche Tourenwagen Masters (DTM) racing championship in his Vodafone-liveried CLK race car.
To celebrate this achievement, Mercedes-Benz and AMG decided to create a limited-edition road car. The standard procedure for such a celebration usually involves a unique paint job, some special badging, and perhaps slightly stiffer springs. But AMG took a radically different approach. They decided to build a road-going replica of the DTM race car.
The result was the Mercedes-Benz CLK DTM AMG. Limited to just 100 Coupes (produced in 2004) and 80 Cabriolets (produced in 2006), it remains one of the most aggressive, rarest, and most highly sought-after AMG models ever constructed. It bridges the gap between the luxury of a Mercedes coupe and the raw violence of a touring car.
The Design: Blistered and Brutal
A standard C209-generation CLK is a handsome, relatively understated luxury coupe. The CLK DTM AMG looks like it wants to start a bar fight.
The exterior modifications are extensive and functional, drawing heavily from the actual DTM race car:
- Carbon Fiber Widebody: The front and rear fenders are massively flared to cover the widened track and massive tires. These flares are made entirely of carbon-fiber-reinforced plastic (CFRP).
- Aerodynamics: The front bumper features a deep carbon-fiber splitter and aggressive air intakes. At the rear, a prominent carbon-fiber diffuser and a large, fixed carbon-fiber rear wing dominate the profile.
- Lightweight Components: The hood and doors are also crafted from carbon fiber, significantly reducing the overall weight.
The result is a car that looks comically wide and uncompromisingly aggressive. It completely abandons the stealthy “Q-car” ethos of a traditional AMG in favor of outright visual intimidation.
The Heart: The Ultimate M113K
While the actual DTM race cars were powered by naturally aspirated 4.0-liter V8s restricted to around 470 horsepower, AMG decided the road car needed significantly more firepower.
They turned to their legendary M113K engine—a 5.4-liter (5,439 cc) V8 featuring a Lysholm-type twin-screw supercharger. This engine was widely used across the “55 AMG” lineup (E55, SL55), but for the CLK DTM, it was heavily modified.
AMG engineers revised the crankcase, upgraded the pistons and valve gear, modified the cooling system, and increased the supercharger boost pressure. The exhaust system was replaced with a bespoke, free-flowing sports exhaust.
The result was a monumental output of 582 PS (574 hp) at 6,100 rpm and a tire-shredding 800 Nm (590 lb-ft) of torque at 3,500 rpm. At the time of its release, it was one of the most powerful engines Mercedes-Benz had ever placed in a production car, eclipsing even the mighty SL55 AMG.
Drivetrain and Suspension: Race-Derived
Power is sent exclusively to the rear wheels via a 5-speed automatic transmission (the AMG Speedshift). While a 5-speed auto seems antiquated today, it was the only gearbox in the Mercedes arsenal capable of handling the 800 Nm of torque without disintegrating. However, for the CLK DTM, the shift times were significantly shortened, and the torque converter lock-up was programmed to be much more aggressive.
To harness this power, the suspension was completely overhauled. It features height-adjustable spring struts (coilovers) at all four corners, allowing the owner to fine-tune the ride height and corner weights. The rear axle utilizes newly developed spring links and hub carriers, and the entire suspension uses stiff uniball joints (heim joints) instead of rubber bushings. This transmits every nuance of the road surface directly to the chassis, providing race-car levels of feedback at the cost of ride comfort.
A mechanical multi-plate limited-slip differential ensures the massive torque translates into forward momentum rather than just tire smoke.
The Spartan Interior
Opening the lightweight carbon-fiber doors reveals an interior that perfectly matches the exterior aesthetic.
The heavy, luxurious electric front seats were discarded in favor of incredibly tight, lightweight carbon-fiber racing bucket seats trimmed in leather and Alcantara, complete with four-point racing harnesses (standard three-point belts were also retained for road legality).
The rear seats were entirely removed. In their place is a structural carbon-fiber panel and a prominent steel roll cage. The steering wheel is a bespoke, oval-shaped unit wrapped in high-grip suede, featuring prominent buttons to control the transmission. Massive amounts of exposed carbon fiber cover the center console and door panels.
Performance and Exclusivity
The CLK DTM AMG is blisteringly fast. The sprint from 0 to 100 km/h (62 mph) takes just 3.9 seconds, a remarkable figure for a rear-wheel-drive car in 2004. Top speed is electronically limited to 320 km/h (199 mph).
Because of its extreme rarity and motorsport pedigree, the CLK DTM AMG immediately became a collector’s item. Ownership was largely restricted to VIP clients and elite racing drivers. Famous owners included Formula 1 drivers Jenson Button, Takuma Sato, and Kimi Räikkönen.
The Mercedes-Benz CLK DTM AMG is a rare example of a German manufacturer letting its engineers off the leash. It is loud, stiff, uncompromised, and incredibly special—a true homologation celebration that successfully brought the violence of the DTM to the public road.
