Following a dominant era with Group A regulations, the Deutsche Tourenwagen Meisterschaft (DTM) shifted to the more open ‘FIA Class 1’ rules in 1993. Mercedes-Benz, the reigning champion, entered with an updated version of their reliable 190 E. However, they faced a fierce challenge from newcomers Alfa Romeo, whose advanced 155 V6 TI was purpose-built for the new regulations. Despite a strong effort, Mercedes-Benz witnessed Nicola Larini and Alfa Romeo seize both the driver’s and manufacturer’s titles.
This defeat on home ground ignited a fire within Mercedes-Benz and their performance division, AMG. For the subsequent 1994 DTM season, they engineered an entirely new contender: the 1994 Mercedes-Benz C-Class, based on the recently launched ‘W202’ sedan. While maintaining the production car’s steel monocoque structure, significant modifications were implemented to create a formidable racing machine. The front section was replaced with a custom subframe to house the engine and a sophisticated double wishbone front suspension. This system incorporated pull-rod actuated springs and dampers, showcasing advanced engineering for enhanced track performance. The rear suspension mirrored this high-tech approach, employing a multi-link design also with pull-rod actuated springs and dampers.
Under FIA Class 1 regulations, the 1994 Mercedes-Benz C-Class DTM was equipped with cutting-edge features. Ventilated disc brakes were augmented with ABS, and traction control systems were integrated to manage the immense power. Departing from the previous four-cylinder engines, a brand-new, naturally aspirated V6 engine was developed specifically for this racing application. Displacing just under 2.5 liters and loosely inspired by the larger 4.2-liter V8 found in models like the E 420 and S 420, this new engine featured a 90-degree V-angle. Despite its robust power output of approximately 400 bhp, achieved through twin overhead camshafts and four valves per cylinder, the engine was remarkably lightweight at only 110 kg, thanks to extensive use of alloys. Power was delivered through a six-speed sequential gearbox, positioned at the rear of the car to optimize weight distribution. In contrast to the all-wheel-drive Alfa Romeo, the 1994 Mercedes-Benz C-Class DTM retained a rear-wheel-drive configuration, aligning with the drivetrain layout of its road-going counterparts.
The 1994 Mercedes-Benz C-Class DTM represented a significant leap forward for Mercedes-Benz in DTM racing. Engineered as a direct response to the challenges of the 1993 season, it showcased advanced technology and meticulous design, setting the stage for Mercedes-Benz’s renewed assault on the DTM championship.
