2019 Deutsche Tourenwagen Masters

Rule changes

Technical regulations

Engine formula

• The 2019 season saw the introduction of a brand-new prototype road car-based fuel-efficient engine configuration, with turbocharged engines returned to the sport for the first time since 1989. The new engines were inline-4 cylinder format single-turbocharged engines, tuned to produce approximately and limited to 9,500 rpm as it was announced on 20 January 2016 and thus the new engine formula will be known as "Class 1" that based on Nippon Race Engine as it used by Japanese Super GT and Super Formula; Garrett Advancing Motion would provide the TR35R turbochargers for all DTM cars from 2019 onwards that same specification as GT500 class in Super GT. Individual engine units under the 2019 specifications had to last for at least before being replaced, in comparison to the pre-2019 engines, which were required to last for. Engine unit changes during a race weekend result in a 10-place grid penalty for the requisite driver. All engines would remain to run on Aral Ultimate 102 RON unleaded fuel. The traditional naturally-aspirated V8 engines that were used since 2000 were permanently retired. The all-new engine configuration also incorporates the IndyCar-style push-to-pass overtake assist system in a bid to improve the racing spectacle; the push-to-pass system will produce around and will be used by the driver up to 12 times in a race.

Aerodynamics and other components

• The single-plane element rear wing returns for the first time since 2016 but would be wider. As a result, the Drag Reduction Systems used for assisting overtaking maneuvers will be revised, with use now within three seconds of a driver in front.
• The minimum weight of the cars was decreased from to account for the decreased weight of the engine and other components.
• Launch control was outlawed, while the traditional interior rear view mirror was replaced by a rear-view camera. Meanwhile all electronic devices were upgraded due to new Class 1 regulations including all-new Bosch DDU 10 color display dash, Bosch MS 7.4 engine management system, Bosch PBX 190 power management systems and also Tyre Pressure Management Systems.

Sporting regulations

• The two races per round format was retained, but the fixed lap distance format was initially brought back, replacing the timed race format that had been used for the previous 4 years; there was a caveat in the case of a safety car period, the race could be extended by up to 3 laps. However after the opening round of the season, the previous timed race format was reinstated with the addition of the race-extending safety car rule.

Manufacturer and team changes

• After 19 years utilised the Mugen Honda MF308-derived engine, the Audi RS5 Turbo DTM would use the in-house bespoke inline-four turbo engine.
• Aston Martin entered the championship, replacing Mercedes-Benz, with cars based on the Vantage. The entry is run by AF Racing AG and built by HWA.

Mid-season changes

1	Calendar changes With the adoption of Class 1 regulations, the series will share two rounds with the Super GT championship. One is planned to be held in Europe and the other in Asia. A balance of performance formula will be applied to ensure parity between DTM cars and Super GT as Super GT will not adopt Class 1 regulations until 2020. The rounds at the Hungaroring, Red Bull Ring and Zandvoort were removed from the schedule. The series will instead make its debut at the TT Circuit Assen and return to Circuit Zolder for the first time since 2002. Meanwhile the Misano round will revert to a daytime start time instead of nighttime. A non-championship race will be held at Fuji as a supporting event of the Super GT x DTM Dream Race.
