Dauer was a German automotive company founded by former racing driver Jochen Dauer in Nuremberg. Initially founded as Jochen Dauer Racing in 1987, the team raced in European and World Sports-Prototype Championship with the Porsche 962. Following the demise of sports prototype racing in the early 1990s, Dauer Racing GmbH was created to begin limited production of road cars, in particular a road-legal version of the 962, known as the Dauer 962 Le Mans. Financially supported by several orders for the Dauer 962 from the Brunei Sultanate and with the success of the race-derivative Dauer 962 at the 1994 edition of the 24h of Le Mans, Jochen Dauer was thinking forward. Why not relaunch a supercar whose career was thwarted by unfavorable circumstances, the Bugatti EB110, in particular the Supersport version whose production did not reach its full potential due to lack of parts. In 1997, Jochen Dauer was one of the main buyers at the auction of Bugatti Automobili's assets in Campogalliano. In 1998, new negotiations were taking place, probably with B-Engineering and Pastor's Monaco Racing Team, to complete the stock of spare parts and engines, as well as some unfinished cars. From that point on, the Dauer's company changed its social reason into Dauer Sportwagen GmbH, the workshop was completely relooked in order to complete the assembling of the unfinished Bugatti EB110s, bought at knock-down prices at the auction. Dauer's main problem was to be able to homologate the cars produced : there were more chassis than homologation titles available. Among the parts and cars bought at the auction, there are cars to be finished (with the authorization to use the Bugatti logo if the car has homologation documents) but there are also bare chassis. The idea is to build as many cars as possible using all these chassis, even if it means homologating the cars under its own name with the German TUV. These cars were homologated as Dauer EB110 S, and it was the occasion for Dauer to upgrade the definition of the EB110, with a lighter carbon body, more powerful engines, more modern equipment...
Around 2005, Jochen Dauer ran into trouble with the Treasury authorities and the company was declared bankrupt in 2008.
