The DTM and Super GT championships could come together for special "exchange races" as a result of the new tie-up between the two series.
The German and Japanese series announced on Tuesday that they will share technical regulations starting in 2014. The deal offers DTM marques Audi, Mercedes and BMW the chance to compete in Japan, while opening the door for Super GT competitors Toyota, Nissan and Honda to race in Europe.
Massaki Bandoh, chairman of Super GT promoter GTA, hinted that the agreement could lead to the championships joining forces to create big events where the DTM and Super GT take each other on.
"We believe that this agreement will contribute greatly to the development of both the Super GT and DTM race series," said Bandoh. "We also think that deepening the relationship between DTM and Super GT toward the future may lead to new developments. [Ideas] such as organizing exchange races for both series have got what it takes to bring new excitement and pleasure to fans around the world."
It has also been confirmed that joint technical working groups will be formed between the championships, manufacturers and promoters, leading to what was described in a statement as "a continuous exchange of information."
