The 2018 Deutsche Tourenwagen Masters was the thirty-second season of premier German touring car championship and also nineteenth season under the moniker of Deutsche Tourenwagen Masters since the series' resumption in 2000. 2018 would be the final season for the traditional 4.0-litre V8 naturally-aspirated engine package that debuted in the inaugural reborn season; as the brand new engine package has been introduced for the following season as part of the "Class One Project" prospect with Japanese Super GT GT500 cars. 2018 also marked the final season for Mercedes-AMG in DTM due to Mercedes-AMG departing to FIA Formula E from the 2019–20 season and thus ended its 19 year participation.
Gary Paffett won his second title at the final round of the season with a third place finish, beating previous champion René Rast by four points despite a late charge to six consecutive wins by Rast, a new series record.
Paffett became the second non-German driver to have won more than one DTM driver title, and thus repeating Swedish driver Mattias Ekström's feat in 2004 and 2007 seasons.
Mercedes-AMG won the manufacturer's championship for the first time since 2010.
Aerodynamic downforce aids, such as side winglets and side fences, has been enforced to all cars, in order to improve competition. As a result, the minimum weight of all cars has been reduced from 2,480 lb (1,125 kg) to 2,458 lb (1,115 kg).
The quantity of engine components a driver may use during the season has been increased from seven complete engines during the entire season, to a new system where each of the engine components are combined. Therefore, in 2018, each driver is permitted to use up to eight set engines.
The additional wildcard entry is introduced for the first time ever, but ineligible for championship points even if they finish in top 10.
