The DTM series, the initials standing for ''Deutsche Tourenwagen Meisterschaft'' until 1996, then following a hiatus, revived as ''Deutsche Tourenwagen Masters'' in 2000, features advanced purpose built 2.0-litre [[four-cylinder]] turbo-powered [[space frame]] machines, covered with largely [[carbon fibre]] bodyshapes resembling the manufacturers' road machine (although the roof and roof pillars do originate from the production car).<ref>{{cite web |author=Audi UK|title=Audi UK > Experience > Motorsport > DTM > The Audi A4 DTM|url=http://www.audi.co.uk/audi/uk/en2/experience/Motorsport/dtm/The_Audi_A4_DTM.html |publisher=Audi.co.uk |date=6 May 2009 |access-date=20 August 2009 |url-status=dead |archive-url=https://web.archive.org/web/20081003102032/http://www.audi.co.uk/audi/uk/en2/experience/Motorsport/dtm/The_Audi_A4_DTM.html |archive-date=3 October 2008 |df=dmy-all }}</ref> In order to lower costs, the engine power is limited to {{convert|610|hp|abbr=on|kW}},<ref>{{Cite book|url=https://books.google.com/books?id=m8TsygLyfSMC&q=In+order+to+lower+costs,+the+engine+power+is+limited+to+600+hp+(450+kW)&pg=PA556|title=Biographical Dictionary of the History of Technology|last1=Day|first1=Lance|last2=McNeil|first2=Ian|date=2002-09-11|publisher=Routledge|isbn=9781134650200|language=en}}</ref> and transmissions, brakes and tyres (Hankook) are standard parts for all. Also, dimensions and aerodynamics are equalised. The approx. {{convert|985|kg|lb|abbr=on}} (without driver) DTM cars corner incredibly quickly and wear spectacular bodykits incorporating huge wheel arches and diffusers, plus a drag-reduction system (DRS) designed to encourage overtaking.

More than 20 works-backed entries of the [[Opel Astra]], [[Audi TT]] and [[Mercedes-Benz CLK]] contested the revived 2000 DTM series but a serious issue developed for the series when Opel pulled out ahead of the 2006 season.<ref>{{Cite web|url=https://au.motorsport.com/dtm/news/opel-to-be-withdrawn-after-2005/1184209/|title=Opel to be withdrawn after 2005|website=au.motorsport.com|date=24 October 2004 |language=en|access-date=2020-02-26}}</ref> BMW would eventually replace Opel as the series' third manufacturer for 2012,<ref>{{Cite web|url=https://www.caradvice.com.au/109900/bmw-to-enter-dtm-series-in-2012-with-six-m3-touring-cars/|title=BMW to enter DTM series in 2012 with six M3 touring cars {{!}} CarAdvice|website=CarAdvice.com|language=en|access-date=2020-02-26}}</ref> while [[Mercedes-AMG]] withdrew at the end of 2018.<ref>{{Cite web|url=https://au.motorsport.com/dtm/news/mercedes-to-quit-dtm-after-2018-confirms-formula-e-entry-934184/3037794/|title=Mercedes to quit DTM after 2018, confirms Formula E entry|website=au.motorsport.com|date=24 July 2017 |language=en|access-date=2020-02-26}}</ref> Mercedes-AMG was replaced by a privately funded [[Aston Martin]] [[Aston Martin Vantage DTM|Vantage]] program that did not last beyond the 2019 season.<ref>{{Cite web|url=https://au.motorsport.com/dtm/news/rmotorsport-aston-martin-vantage-hwa/4678089/|title=Aston Martin rules out HWA running Vantages in DTM|website=au.motorsport.com|date=29 January 2020 |language=en|access-date=2020-02-26}}</ref>

For the 2019 season, major technical changes occurred. Turbochargers were reintroduced in accordance with new regulations impacting engines and power outputs, as all cars are now required to have 2.0-litre 4-cylinder single turbo engines, replacing the 4.0L V8s that had been used since the series' revival in 2000. Engine power was increased from ~500&nbsp;hp to 610&nbsp;hp, with an extra 30&nbsp;hp available as part of a [[Push-to-pass|push-to-pass system]] available to drivers for the first time.<ref>{{Cite web|url=https://www.audi.com/en/experience-audi/audi-sport/audi-racing-models/rs-5-dtm.html|title=RS 5 DTM|website=audi.com|language=en|access-date=2020-02-26|archive-date=7 March 2021|archive-url=https://web.archive.org/web/20210307231407/https://www.audi.com/en/experience-audi/audi-sport/audi-racing-models/rs-5-dtm.html|url-status=dead}}</ref><ref>{{Cite web|url=https://www.bmw-motorsport.com/en/topics/magazine-article-pool/dtm-class-1-era-turbo.html|title=BMW M4 DTM Turbomotor|website=www.bmw-motorsport.com|language=en-SM|access-date=2020-02-26}}</ref> Downforce levels were also reduced to encourage overtaking and increase top speeds to 300&nbsp;km/h (186&nbsp;mph) in order to improve the racing spectacle.<ref>{{Cite web|url=https://www.autosport.com/dtm/news/140837/dtm-2019-cars-will-be-23s-faster|title=DTM's Class One cars for 2019 season will be 2-3s faster|last=Errington|first=Tom|website=Autosport.com|language=en|access-date=2020-02-26}}</ref>

In 2019, DTM formed a partnership with the Japanese sports car series [[Super GT]] which runs a near identical set of rules and regulations in its GT500 class. Honda, Toyota – represented via [[Lexus]], and [[Nissan]] each entered a wildcard entry for the final race of the 2019 season at the [[Hockenheimring]]. The cars entered were a [[Nissan GT-R]] (R35), a [[Lexus LC 500]] and a [[Honda NSX (second generation)|Honda NSX]]. For the weekend of the 22nd-24 November, DTM sent three BMW M4s and four Audi RS5s to take part in a non-championship race at [[Fuji Speedway]] along with the full GT500 grid, labelled the 'SUPER GT x DTM Dream Race'. Aston Martin withdrew from the event as they intended to focus on developing the Vantage package for 2020, however this never eventuated as the program was ended.<ref>{{Cite web|url=https://www.touringcartimes.com/2019/09/14/r-motorsport-miss-dtm-super-gt-joint-race-fuji/|title=R-Motorsport to miss DTM and Super GT joint race at Fuji|date=2019-09-14|website=TouringCarTimes|language=en-US|access-date=2020-02-26}}</ref>

Audi announced in late April 2020 that they would be discontinuing their involvement in the series after the end of the 2020 season, following the same path Mercedes-Benz did after the end of the 2018 season; focusing on electric motorsport, most notably [[Formula E]]. This will leave BMW as the sole manufacturer left, putting the series' future in serious jeopardy.<ref>{{Cite web|url=https://www.autosport.com/dtm/news/149182/audi-to-quit-dtm-at-the-end-of-2020|title=DTM News: Audi to quit series at the end of 2020|date=2020-04-27|website=Autosport.com|language=en|access-date=2020-06-30}}</ref>
