As early as 1998 at the Essen Motor Show, Opel showed a DTM touring car based on the Opel Astra Coupé, which showed developments in German touring car racing. In 2000, Opel presented the Astra Coupé for the 2000 DTM season . This season was the most successful for the Astra Coupé with eight race wins and the runner-up for Manuel Reuter . In the following years, the Astra was no longer capable of winning in the DTM.
In the 2001 DTM season it was permissible to increase the wheelbase due to regulations and to deviate from the standard wheelbase. In addition, the rear wing was allowed to be positioned further behind the car this season. Opel built a completely new development of the Astra with a lot of complicated technology that overwhelmed the teams.
In the 2002 DTM season, Opel took advantage of a loophole in the regulations: the new double-decker standard rear wing presented at the season opener in Hockenheim had two "ears" on the sides. However, these aerodynamic aids were declared as rear wing holders. Nevertheless, Opel was not able to convince much this season; the best result was Alain Menu's third place at the Sachsenring .
The aerodynamics of the vehicles were adjusted again in the 2003 DTM season . So Opel was again made some concessions, but the "ears" were forbidden. Even so, Opel was not very competitive. However, Peter Dumbreck , coming from Mercedes-Benz , who even achieved second place at the EuroSpeedway Lausitz , was able to set accents again and again . Although brought Scheider in Zandvoort pole position, but after a failed pit stop it turned out in the lead.
The Opel works team and their Phoenix team started in 2003 with a slightly modified DTM car from the previous year at the Nürburgring 24-hour race . The Astra had already been tested on the Nordschleife as part of VLN races . In the 24-hour race, they competed against the works teams from Audi (who also fielded a DTM car with the TT-R) and BMW in the battle for overall victory. After 24 hours the Opel team, unsuccessful in the DTM, celebrated a sovereign victory. The following year, Opel tried to defend victory. While the DTM had meanwhile switched to the Opel Vectra GTS V8 , the Nordschleife continued with a modified 2003 DTM Astra. However, it was not possible to build on the previous year's success. This ended Opel's works involvement in the 24-hour race at the Nürburgring.
Other uses
The modified Astras for the Nordschleife went into private hands. The Schall team drove the Astra V8 Coupé for several years as part of the VLN. Other Astras from the DTM are still used in hill climbs.
