1994 Mercedes-Benz C-Class: AMG’s DTM DominanceBorn from the crucible of motorsport rivalry, the 1994 Mercedes-Benz C-Class DTM car emerged as a direct response to a humbling defeat on home turf. After a decade under Group A regulations in the Deutsche Tourenwagen Meisterschaft (DTM), the dawn of the 1993 season heralded the ‘FIA Class 1’ era, a set of rules promising greater technical freedom. Mercedes-Benz, the reigning champion, initially entered an updated iteration of their reliable 190 E. However, the landscape shifted dramatically with the arrival of Alfa Romeo and their cutting-edge 155 V6 TI, engineered from the ground up for these new regulations. Despite a valiant effort, the older Mercedes-Benz was outpaced, ceding both driver’s and manufacturer’s championships to Nicola Larini and Alfa Romeo respectively.

This setback ignited a fire within Mercedes-Benz and their performance division, AMG. For the subsequent 1994 DTM season, they embarked on developing an entirely new challenger. The foundation for this machine was the recently launched ‘W202’ C-Class sedan, a symbol of modern Mercedes-Benz engineering. While retaining the production car’s steel monocoque chassis, AMG engineers undertook a radical transformation. The front section, ahead of the cockpit, was surgically removed and replaced with a custom-designed subframe. This bespoke structure became the anchor point for the engine and a sophisticated double wishbone front suspension system, complete with pull-rod actuated springs and dampers – a hallmark of advanced racing technology. The rear suspension mirrored this complexity, employing a multi-link design also utilizing pull-rods for spring and damper activation. Embracing the technological freedom of FIA Class 1, the 1994 Mercedes-Benz C-Class DTM incorporated cutting-edge features like ABS for the ventilated disc brakes and traction control systems, pushing the boundaries of performance and handling.

Under the hood, the aging four-cylinder engine of previous seasons was superseded by a brand-new, high-revving V6 powerplant, displacing just under 2.5 liters. Loosely inspired by the 4.2-liter V8 found in the E 420 and S 420 road cars, this new engine adopted a 90-degree V-angle configuration. Featuring double overhead camshafts and four valves per cylinder, this compact yet potent unit was constructed with extensive use of lightweight alloys, resulting in a remarkably low weight of only 110 kg. Generating approximately 400 bhp, this engine was mated to a race-bred six-speed sequential gearbox. Strategically positioned at the rear of the car, this transaxle arrangement contributed to a more balanced weight distribution, crucial for optimal handling and performance on the track. In contrast to the all-wheel-drive system employed by the Alfa Romeo, the 1994 Mercedes-Benz C-Class DTM racer remained faithful to its road-going counterpart’s rear-wheel-drive configuration, as no production C-Class models offered all-wheel drive at the time. This commitment to rear-wheel drive presented a unique engineering challenge and highlighted Mercedes-Benz’s focus on mastering traditional drivetrain dynamics within the demanding FIA Class 1 regulations.
