Irmscher Automobilbau GmbH & Co. KG is a German car tuning and manufacturing company, specialising in Opel, Peugeot and Kia vehicles as well as working for the complete automotive industry as an engineering service provider.
It was founded in 1968 in a double garage in the Swabian town of Winnenden (near Stuttgart) by rally driver and mechanic Günther Irmscher.
Irmscher has retained close links to the Opel company by operating the factory team in many European and German automobile competitions, such as the World Touring Car Masters, where they won the D Class championship in 1990 with driver Bernd Schneider. In 1991 the team decided to run under the Vauxhall Sport name as they switched from Opel to Vauxhall, keeping Schneider and bringing in 1988 WTCM champion Tim Harvey.
For 1992 Vauxhall Sport would switch to a British licence, however the team would remain in a co-operation between Irmscher and British team RML.
