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-Benz supported expensive competitiveness in development, BMW wanted an international series rather than one focused 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. The DTM returned in 2000 as Mercedes and Opel had agreed to use cars that were based on the concept car that was shown by Opel on various occasions, e.g. the 1999 24 Hours Nürburgring where Opel celebrated its 100th anniversary. The series adopted the format of the 1995 championship, with most rounds held in Germany with occasional rounds throughout Europe, but having learnt the lessons of the ITC disaster, the ITR constantly strived to keep costs in the series from exploding to unreasonable levels, and to keep the championship firmly tied to its German roots. As too many races were planned outside Germany, no Championship (Meisterschaft) status was granted by the DMSB, and the DTM initials now stand for Deutsche Tourenwagen Masters (German Touring Car Masters). The cars are supposed to be fast and spectacular, while still rather cheap to build and run. All DTM race cars have RWD and 4.0 L V8 engines which are air-restricted to 470 hp, no matter if similar layouts or engines are available in the road cars. Instead of the road car bodies, unrelated purpose-built chassis are used, which are closer to prototype racing. Many drivers have in fact described the handling of the cars as closer to single seater racing cars than road cars. Only the roof sections of the road cars are put on top of the roll cages, and lights and other distinctive design features are used in order to provide a resemblance to the road cars. Also, in order to save money and provide close racing, many common parts from third party specialist are used, like transmission (from Hewland and Xtrac), brakes, and Dunlop Tyres, although since 2011, Hankook tyres. The all-important aerodynamic configurations are tested in wind tunnels before the season, brought to an equal level, and kept that way throughout the season. DTM cars adhere to a front engine rear-wheel-drive design. A roll cage serves as a space frame chassis, covered by a CFRP crash elements on the side, front and rear and covered by metallic bodywork. They have a closed cockpit, a rear wing, and an aerodynamic such as rear wing: mono-wing with laminated gurney. Inclination adjustable from 0 to 20°. Special diffusors, front and rear. Underfloor with 30 mm high skid block. Two permissible areas for flaps at the vehicle’s front end. DTM cars are included Drag Reduction Systems since 2013 season (similar to Formula One). The cars are powered by EFI V8 engines, with cast iron blocks, and a 2xDOHC valvetrain actuating four-valves per cylinder, and limited to 4,000 cc (4 l) displacement. DTM car's engines are powered 500 hp (373 kW; 507 PS). DTM engines are rev-limited to 9,000 rpm. The valve train is a dual overhead camshaft configuration with four valves per cylinder. The crankshaft is made of alloy steel, with five main bearing caps. The pistons are forged aluminum alloy, while the connecting rods are machined alloy steel. The electronic engine mana...
