The Team was Ruch Motorsport, bzw, a pure privateer effort.

The return of the DTM legends: Gerd Ruch and his Mustang

Munich (12.03.2021) - "It's simply incredible how much fan mail I still receive today. I get pictures sent to me that I've never seen before," says Gerd Ruch. The Berliner is visibly impressed. His joy is also clearly palpable when he talks about the plans to return to the Norisring for the DTM Classic touring car legends races. It would be the return of two DTM legends: Gerd Ruch and his Mustang.

Gerd Ruch was the favorite of the DTM fans, he was the classic underdog, a private driver through and through. He was something like the Don Quixote of the DTM, and his Mustang was more or less his horse Rosinante - not because the Mustang was rickety, but because the duo of Ruch and Mustang had no chance against the professionals and the manufacturers. But Gerd Ruch didn't mind, because he had fun working all night and then racing. "My success was that my car lasted and I often saw the chequered flag," he says, describing his boundless idealism.

Gerd Ruch, who still earns his money with his own building technology company, contested over 100 DTM races between 1988 and 1995, finishing tenth twice. "That was a great time!" he literally blurts out. "Especially the last year with the Mustang, in 1994, was really great," he says. "In the beginning, the Mustang's technology was stoneage, but in the end it was a really good racing car.
We developed everything ourselves. We only got help from Bosch and Mercedes with the ABS installation."

The beefy sound of the five-liter V8 engine was enough to excite any eardrum. A good 540 hp was available, but the torque of over 650 Newton meters was even more impressive. "Our biggest shortcoming was the tires, because only older tires were available." Alongside his brother Jürgen, Jürgen Feucht was also one of the Mustang riders at the time. "Jürgen Feucht contacted me some time ago and happily told me how the Mustang drove with new, up-to-date tires. He said: "If we had had these tires back then, we would have looked much better."

Gerd Ruch contested the 1995 DTM with a Mercedes-Benz C-Class, with which Norbert Haug wanted to keep the public's favorite in the DTM. But the fans resented the change and sensed betrayal. After his time in the DTM, Ruch drove for two more years with Porsche in the FIA GT Championship, then switched to flying and now the 67-year-old, who continues to follow the DTM on TV, has devoted himself to golf, especially on his favorite island of Mallorca.

While his brother's Mustang was sold to Finland years ago, his Mustang stood in the corner of his company hall. When his company downsized in autumn 2020, he wanted to part with his former "DTM treasure". A friend took care of it, and there were numerous offers from Germany and abroad, which Gerd Ruch would never have expected. In the end, as fate would have it, the car stayed in Berlin - with Mücke Motorsport. "Stefan Mücke is a really nice guy. It was fun to help him rebuild the car. I still had a lot of parts, and I also re-established some contacts in the USA." Even a new roll cage was welded into the Ford Mustang 5.0 GT, as the registration of the original cage had expired.

The Ruch Mustang is now owned by Guido Momm, a real estate entrepreneur who lives in Kelberg, not far from the Nürburgring. Momm intends to contest the Legends races of the DTM Classic presented by the AvD with the Mustang fielded by Mücke Motorsport - and at the Norisring, Momm wants to share the cockpit with Gerd Ruch.
