The new North American-based DTM series will start in 2017 at the earliest, at least a year later than planned.
DTM promoter the ITR announced on Saturday at the Norisring that the date for adoption of the series rules by both Grand-Am and Super GT had now been rubber-stamped. This followed the first meeting of a new steering committee, featuring representatives of the DTM, Super GT and Grand-Am plus the respective motorsport federations of Germany, the USA and Japan, on Friday.
United SportsCar Racing, which will run the North American series, announced in March that it was targeting an inaugural season in 2015 or '16. However, this has now been moved back to 2017 at the earliest. Since the announcement the DTM had revealed plans to change its own technical regulations and adopt a two-liter turbocharged engine formula for '16.
ITR chairman Hans Werner Aufrecht said: "The common goal of all the parties within the steering commission is to use common regulations from 2017 onward. It is an important first step."
The next meeting of the Steering Committee is expected to take place at Daytona during next year's 24-hour race.
