The Deutsche Tourenwagen Masters, commonly abbreviated as the DTM, is a sports car racing series sanctioned by ADAC. The series is based in Germany, with rounds elsewhere in Europe. The series currently races a modified version of Group GT3 grand touring cars, replacing Class 1 Touring Cars in 2021.
From 2000 to 2020, the "new DTM" continued the former Deutsche Tourenwagen Meisterschaft (German Touring Car Championship) and ITC (International Touring Car Championship) which were discontinued after 1996 due to high costs. The series raced prototype silhouette racing cars based on mass-production road cars in the same period.
The second iteration went by the full name during its first five years. Since 2005, all official documents have only referred to the series using the abbreviated name.
History Background
During the ITC era, a large proportion of the revenue generated by the championship went to the FIA, which led to complaints from the teams regarding the small return on their increasingly large investment in the high-tech touring car series. Since 1997, many ideas had been discussed in order to find a compromise for the rules of a new DTM racing series. Opel put the primary emphasis on cost control, Mercedes-Benz supported expensive development in competition, BMW wanted an international series rather than one focused on Germany only, while Audi insisted on allowing their trademark quattro four-wheel drive system (despite running the rear wheel drive Audi R8 in sports car racing).
DTM returned in 2000 as Mercedes and Opel had agreed to use cars that were based on the concept car that was shown by Opel on various occasions (e.g. the 1999 24 Hours Nürburgring where Opel celebrated its 100th anniversary). The series adopted the format of the 1995 championship, with most rounds held in Germany and occasional rounds throughout Europe, but having learnt the lessons of the ITC format, the ITR constantly made efforts to keep costs in the revived series and the championship firmly tied to its German roots. As too many races were initially planned outside Germany, no Championship (Meisterschaft) status was granted by the DMSB, and the DTM initials now stand for Deutsche Tourenwagen Masters (German Touring Car Masters).
Unlike the previous incarnation, which primarily used saloon models like the Mercedes-Benz W201, the new DTM featured only 2-door coupés. Opel used the upcoming Coupé version of the Astra as the concept car, and Mercedes used the CLK model which was already used as the basis for the Mercedes-Benz CLK-GTR GT1-class sports car.
The motorsport arm of the Bavarian tuning company Abt Sportsline was allowed to enter on short notice. Abt used the Audi TT as a basis for a DTM car, as Audi had no suitable 2-door coupé in its model lineup at the time, even though the dimensions of the car did not fit into the rules of the series. This also meant that the 1999 STW-Supertouring-champion Christian Abt could not defend his STW title as this series was also discontinued, with Opel then moving into DTM.
2000–2003 In May 2000, the new DTM started with the traditional Hockenheimring round on the short course. Some cars competing in the race had no or few sponsorship decals. While Opel's cars could match the speed of most Mercedes cars in the 2000 season, the hastily developed Abt-Audi ended up outclassed. As the body shape of the TT had rather poor aerodynamics, Abt was allowed to use a version with a stretched wheelbase and bodyshell in later years. Further dispensation was also granted, such as increased rear wing height, which helped the Abt-Audi TT-R win the DTM championship in 2002 with Laurent Aïello.
In 2002, DTM also introduced the HANS device to increase driver safety and reduce injuries from accidents. In 2000, Manuel Reuter came second in the championship. After that year, no Opel driver was among the top three in the overall championship, with few podium finishes and no victories for the disappointing "lightnings". On the other hand, it was Opel team boss Volker Strycek who brought a new highlight to the fans, by racing a modified DTM car on the old version of the Nürburgring in 2002, 20 years after the top classes had moved to the modern Grand Prix track, and ten years after the old DTM stopped racing there. The Opels did not win in many of their race entries in the VLN endurance racing series, as they were mainly testing. Opel won the 2003 Nürburgring 24 Hours against factory efforts by Audi, who also ran a DTM-spec TT and BMW, who ran an ALMS-spec M3.
2004—2006 After their successes with the Audi R8 and the official support of the Abt-TT-Rs at the Nürburgring, Audi finally joined the DTM as a factory entrant in 2004. The three constructors involved decided to switch to D-segment compact executive-based saloon bodies. The road models used as patterns since 2004 are the Audi A4, Opel Vectra GTS and the Mercedes-Benz C-Class. All dimensions, like the wheelbase, are identical in order to provide equal opportunities without the actual design of the road cars having any influence. Audi immediately had success in 2004 with Swedish driver Mattias Ekström, now a long-time veteran of the sport, becoming a DTM series champion for the first time.
The championship suffered a setback in 2004 when long-time entrant Opel decided to pull out of the series at the end of the 2005 season, as part of a large cost-cutting operation in General Motors' European division. Initially, the gap looked set to be filled by MG Rover, however their plans to enter the series were canceled after the company collapsed in April that year. As a result, Audi and Mercedes ended up fielding 10 cars each in 2006, but the television deal with the major German television station ARD required three marques to participate in 2007 in order to continue the broadcast agreement.
2007–2013 The DTM carried on with only two manufacturers in spite of the television agreement requiring three manufacturers to participate in the series. The 2007–2009 seasons were marked by the dominance of Audi. Swede Mattias Ekström won the second of his two titles in 2007, and Timo Scheider took the driver's championship in the following two years. Mercedes-Benz were in the runner-up positions in both 2008 and 2009 (Paul di Resta in 2008 and Gary Paffett in 2009). In 2010, Mercedes finally bridged the gap to Audi, as di Resta won the 2010 championship driving for AMG-Mercedes.
In 2011 and 2012, the DTM held a Race of Champions-style exhibition event in the Munich Olympic Stadium.
In 2012 BMW made a return to the series after a twenty-year absence, and won the drivers, teams, and manufacturers titles. 2012 also marked the return of three-car manufacturers since 2005 season as well as two-door D-segment compact executive coupé style since 2003.
Audi switched from the A4 to the A5 in 2012 and to the RS5 in 2013. In 2013, the Drag Reduction System identical to the system used in Formula One was introduced by ITR to improve racing in DTM.
2014–2020 In 2014, the body shape and aerodynamic pieces of all DTM cars were modified to improve racing. The double-header races (Saturday and Sunday races) were also revived in 2015, thus switching from races with total laps run to timed races. The qualifying format was also reformatted into a single-session timed qualification (similar to the Formula One qualifying format used from 1996 to 2002), but DTM only run a single 20-minute qualifying session for Saturday and Sunday races. Performance weights were also introduced to determine the winning car's weight.
In 2017, the DTM field size was reduced from 24 to 18 cars total to improve quality as well as increasing affordability for its existing manufacturers, while making the series a more attractive proposition for any prospective entrants and manufacturers.
For the 2019 season, turbocharged engines were reintroduced to the series for the first time since 1989 (see article below for full story). Mercedes left the series following the conclusion of the 2018 season, but R-Motorsport joined the series in 2019 to run four Aston Martin-branded cars, although they would withdraw after a single season that did not yield competitive results. The 2019 season also saw the three Super GT GT500 manufacturers – Honda, Lexus and Nissan – each field a guest entry at the final race of the season, before entries from both series would compete at the non-championship Super GT x DTM Dream Race held at Fuji Speedway in Japan.
2021–present The 2021 season switched to a GT3-based regulation, otherwise known as GT Plus, due to the sudden withdrawal of Audi in 2020 which left only BMW with an eligible Class 1 car. In December 2022, the parent body of the DTM, ITR, was dissolved, leaving ADAC to acquire the rights to the championship name. The DTM continued in name-only from 2023 onwards, with completely different organisation and regulations compared with just three years previous.
International expansion DTM–Super GT unification
In March 2010, The GT Association (the governing body of the Super GT series in Japan) initially announced that the ITR were beginning to align the technical regulations with Super GT's GT500 class and NASCAR's Grand American Road Racing Association Grand Touring division to form a new Grand Touring specification. Touring Car Times. 15 December 2011. In October 2012, a cooperation agreement between DTM and Super GT was signed in Berlin. The agreement regarding the use of the 'New DTM' regulations by Japan's Super GT began in 2014 and ran for four years. DTM moved away from its previous 4.0-litre V8 specification in favour of 2.0-litre turbos in 2019, which Super GT had implemented in 2014.
NASCAR Holdings / IMSA On 27 March 2013, the ITR and NASCAR Holdings road racing division, the International Motor Sports Association announced a North American DTM series that was scheduled to start between 2015 and 2016 based on the 2014 DTM/Class 1 regulations.IMSA, Grand-Am, DTM Agreement NASCAR Holdings press release. 27 March 2013. As of 2019, a North American DTM series has yet to run, despite interest being shown by the North American sanctioning body to run DTM/Class 1, either as a series under IMSA sanction or possible integration into the sports car championship as a potential replacement for the GTLM/GTE class in 2022. The initial 2013 agreement to run a North American DTM Series was signed by IMSA's predecessor, Grand-Am Road Racing and did not take into account the subsequent merger of the sanctioning body with the rival sports car championship American Le Mans Series in 2014 to form the United SportsCar Championship, now known as the IMSA SportsCar Championship. After Class 1 racing in Europe ended entirely in 2020, being replaced by GT3 Specification and GTE Class racing ending globally in 2023 and also being replaced by GT3 Specification, both IMSA and the DTM now use GT3 class racing cars in different states of tune.
Race format When the DTM series returned, it used a similar format to the final season of the former DTM in 1996: two races of 100 kilometres, with a short break between them. In 2001 and 2002 there was a short race of 35 kilometres as well as a long race of 100 kilometres, which included one pit stop and points scored for the top 10 as in earlier seasons. From 2003 to 2014 there was only one race, which had a distance of about 250 kilometres, and two mandatory pit stops.
For the 2015 season a new race format was introduced. Race weekend consisted of 40-minute (Saturday) and 60-minute (Sunday) races. On Saturday's race a pit stop was optional, while on Sunday's race a pit stop was mandatory and all the four tyres had to be changed. Both races had the same scoring system.
