DTM
The Deutsche Tourenwagen Masters (DTM, German Touring Car Masters) is a GT car series based in Germany, with rounds elsewhere in Europe. The series races a modified version of Group GT3 grand touring cars.
The original series of 1984 was first named Deutsche Tourenwagen Meisterschaft but changed its name in 2000. For the 2019 season, turbocharged engines were reintroduced to the series for the first time since 1989. In 2021 the season switched to a GT3-based regulation in order to attract more manufacturers to the series. The competing brands in the 2021 season are: Audi, BMW, Ferrari, Lamborghini, McLaren and Mercedes-Benz.
Here are the main characteristics of the DTM racing format:
-- Two sprint races per weekend, each race is 55 minutes plus one lap
-- Only one driver per car
-- Single 20-minute qualifying session for each race
-- The start is the so-called DTM formation start: a rolling double-file start in close formation in IndyCar style
-- Mandatory pit stop with full tyre change, to be served with a maximum of six mechanics and two wheel guns
-- Driver aids like an Anti-lock Braking System (ABS) and Traction Control (TC) are allowed
-- The use of an independent Balance of Performance (BoP) of the cars, considering: output, capacity, centre of gravity and is also circuit-specific
-- New in the 2021 season is the introduction of the success ballast: the three best-placed drivers of race 1 get respectively added 25, 18 and 15 kilograms to their car for the subsequent qualification 2 and race 2
