The Deutsche Tourenwagen Masters (DTM, German Touring Car Masters) is a Silhouette racing car series based in Germany, but also with rounds elsewhere in Europe.

From 2000 onwards, this new DTM continued the former Deutsche Tourenwagen Meisterschaft (German Touring Car Championship) and ITC (International Touring Car Championship) which had been discontinued after 1996 due to high costs.

During the ITC era a large proportion of the revenue generated by the championship went to the FIA, with the result that less went to the teams who subsequently complained of little return on their increasingly large investment in the high-tech series. Since 1997 many ideas have been discussed in order to find a compromise for rules of a new DTM. Opel put the primary emphasis on cost control, Mercedes supported expensive competitiveness in development, BMW wanted an international series rather than one focussed on Germany only, while Audi insisted on allowing their trademark quattro four-wheel drive (despite running the rear wheel drive Audi R8) in sports car racing.

Bruno Spengler (born August 23, 1983 in Schiltigheim, Bas-Rhin) is a French-born Canadian racing driver, nicknamed 'The Secret Canadian'.

Spengler was born in Strasbourg, France but moved to Saint-Hippolyte, Quebec, Canada, when he was 3. He went to school in Canada but continued to go back to France where he started competing in kart racing in 1995. Spengler continued karting in both France and Canada and then moved on to competing in the French Formula Renault. Eventually this led to him being signed by Mercedes-Benz motorsport and in 2003 he was racing for ASM in the Formula Three Euroseries.

Since 2005 he has driven a Mercedes in the Deutsche Tourenwagen Masters in Germany. In 2005 he ran with Persson Motorsport and he convinced AMG directors to have an official car in 2006. That year he finished the 2006 season second behind his team mate and five times champion Bernd Schneider. He completed the 2007 season campaign once again in second place, this time behind Audi driver Mattias Ekström, despite Audi's mass pull-out in Barcelona.
