The high-tech 1994 Mercedes-Benz C-Class DTM ...

This weekend Jamie Green won the final DTM race of the season, which inspired us to look back at a golden era
of the German touring car championship; the mid-1990s. Between 1993 and 1996, the series used the so-called
'FIA Class 1' regulations, which gave manufacturers considerable freedom in both aerodynamics and electronics.
For the 1994 season, Mercedes-Benz introduced the C-Class DTM, which was based on the recently introduced
'W202' road car.

Following a decade of using Group A regulations, the Deutsche Tourenwagen Meisterschaft (DTM) adopted the much more liberal 'FIA Class 1' rules at the start of
the 1993 season. Reigning champions Mercedes-Benz opted to field an updated version of the tried and trusted 190 E. They were faced with series new-comers,
Alfa Romeo, who entered the hugely sophisticated 155 V6 TI, which had been designed specifically for the new regulations from the ground up. While the ageing
Mercedes-Benz put up a formidable fight, the raw pace of the new 155 gave Nicola Larini and Alfa Romeo the driver's and manufacturer's championships
respectively.

Mercedes-Benz and its competition subsidiary AMG did not take this defeat on home soil lightly and for the next DTM season developed a brand new car.
This was based on the recently introduced 'W202' C-Class sedan. Carried over from the production road car was the unitary steel shell but with the section ahead
of the cockpit cut off. This was replaced by a bespoke subframe that housed the engine and double wishbone front suspension with pull-rod actuated springs and
dampers. The rear suspension was of a multi-link design and also used pull-rods to actuate the springs and dampers. Among the many high-tech features allowed
in FIA Class 1 were ABS for the ventilated discs and traction control.

Replacing the four cylinder engine used during the previous seasons was a brand-new V6 with a displacement of just under 2.5 litre. Very loosely based on the
4.2 litre V8 used in the E 420 and S 420 models, the new engine used a V-angle of 90 degrees. Equipped with twin overhead camshafts and four valves
per cylinder, the compact unit nevertheless only weighed 110 kg due to extensive use of alloys. Producing around 400 bhp, it was mated to a six-speed
sequential gearbox that was fitted at the rear of the car to improve the weight balance. Whereas the Alfa Romeo featured four driven wheels,
Mercedes-Benz was restricted to rear-wheel drive for their new DTM racer as none of the road-going C-Class models used all-wheel drive.

One of the other areas, in addition to the electronics, that the FIA Class 1 left more room to work with than Group A was aerodynamics. The only restriction was
that all aerodynamic devices, except for the rear wing, were fitted lower than the top of the wheel hubs. This resulted in elaborate bumpers and side skirts but also
gave the cars a relatively 'stock' appearance. The DTM racer nevertheless shared no panels with the road-going C-Class as weight saving dictated that all body
parts were made from carbon-fibre. The aforementioned rear wing consisted of two horizontal elements and was mounted on the rear deck.

Mercedes-Benz fielded six examples of the C-Class DTM in 1994 for a hugely talented set of drivers that included 1992 champion Klaus Ludwig and also the
season's only female competitor, Ellen Lohr. Although Opel also fielded a Class 1 Calibra, the victories this year would be divided between the Alfas and
Mercedes. Kurt Thiim took the C-Class' first win in the third of twenty rounds but the fight would remain close throughout the season.
Although Alfa Romeos would claim eleven victories against Mercedes' nine, it was a very consistent run from Ludwig that saw him clinch his second
DTM title for Mercedes-Benz.

The hugely sophisticated machines and exciting races in 1994 had caught the world's eye and for 1995 six international rounds (ITCS or International Touring
Car Series) were added to the roster, each featuring two races. The DTM championship also consisted of six rounds of two races. Both Mercedes-Benz and
Alfa Romeo continued development and on the C-Class the changes included a 440 bhp variant of the V6 and a paddle-operated gearbox. Alfa Romeo had
gone a step too far with electronics and suffered from poor reliability throughout the season. This allowed a very dominant Bernd Schneider to comfortably
win both the DTM and ITCS titles.

For 1996 the two championships were combined into the ITC with the FIA claiming a prominent role and also a stake from the lucrative TV contracts.
By now the lovely little V6 engine developed by AMG produced a staggering 500 bhp but the rivals also had not ceased working. Particularly Opel had
stepped up and Manuel Reuter immediately made his mark by claiming the Calibra's first ever DTM victory in the opening round of the season. It would turn out
to be the most competitive year run under the Class 1 regulations with each of the three manufacturers claiming multiple victories. Defending champion
Schneider won four of the twenty-six races but he was nevertheless just beaten by Reuter, despite having won just three races.

Despite the hugely exciting season, the manufacturers were far from happy, particularly with the way the series was run by the FIA. Perhaps considered a threat
to Formula 1 by the sport's governing body, little was done to promote the championship. This gave the manufacturers relatively little return on their huge
investment. Both Alfa Romeo and Opel had had enough and withdrew, effectively ending the brief spell of the most sophisticated touring cars had ever seen.
The C-Class DTM dominated the better part of two seasons and took three of the five titles up for grasps in those four seasons. In 2000 the DTM series was
reinstated and his since thrived free from FIA control and with Mercedes-Benz as one of the dominant teams.

One of the 1994 cars, this C-Class DTM was raced that year by Ellen Lohr. Team mate of champion Klaus Ludwig, Lohr finished the year in 11th, having scored
a single podium finish. Painted in the colours used by Roland Asch, another 1994 Mercedes-Benz works driver, the car arrived at the workshop of Dawn Treader
Performance some years ago. They meticulously restored the car to its Lohr configuration, complete with all the sophisticated electronics and finished off with
the elaborate 'D2' livery. It was ready in time for the 2010 Goodwood Festival of Speed where it was one of the fastest cars up the hill in the hands of Gary Ward.
