different models (Astra in 2000–2003 later Vectra GTS V8 in 2004–2005). Opel ended its DTM program after the 2005 season, citing costs and company restructuring. Aston Martin provided the cars to R-Motorsport team in 2019, but left DTM after the 2020 season unable to secure an engine supplier. In 2000, Mercedes-Benz AMG came to the new DTM from the 24 Hours of Le Mans. Mercedes-Benz won their first race in 1st Hockenheimring round, as well as the series title. In July 2017, Mercedes-Benz AMG company officials announced the company's withdrawal from German touring car racing after 2018 season and the immediate discontinuation of its DTM program, coinciding with its entrance into FIA Formula E Championship in 2019, and its discontinuation of its DMSB program. During the first inaugural resumption season, all DTM car styles were utilized shorter S-segment compact sports two-door coupé-style cars until 2003 season but in 2004 coupé-style cars were minority due to the transition to four-door sedan saloon-style cars. In 2004 the four-door sedan saloon-style cars were introduced due to touring car racing's core philosophy (several touring car racing tournaments have a de facto 4-door sedan saloon cars) until 2011. For 2012 season onwards the two-door coupé-style s were returned until 2020 but the two-door coupé-style cars are much more different than 2000–2003 cars (longer length, longer wheelbase, slightly lower height and aggressive aero package as based on compact D-segment compact executive cars). The updated new coupé-style cars were introduced in 2017 thanks to new rear wing. The cars are supposed to be fast and spectacular, while still fairly cheap to build and run. All DTM race cars have RWD and 4.0-litre V8 engines (later 2.0-litre inline-4 turbocharged engines) which are air-restricted to 460 hp but now into over 500 hp since 2017 until 2018 season and now into 610 hp including 30 hp push-to-pass since 2019 season and later 580 hp + 60 hp push-to-pass since 2020 season onwards, 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
