The DTM could introduce the use of a DRS this year and will trial the system in next week's official test at Barcelona.
It is understood that a final decision on whether or not such a system will be used this year will not be made until the next board meeting of series promoter the ITR, and that data gathered in Spain will play a key role in the outcome.
Mercedes team leader Gary Paffett, the 2005 DTM champion, believes that DRS would increase the amount of on-track passing in the series, as it has done in Formula 1 in recent years.
"The DTM is so evenly-matched that it's becoming more and more difficult to overtake each other," Paffett said. "I think the fans would enjoy it a lot if we had something like DRS in the DTM."
Audi driver Adrien Tambay is also in favor of the introduction of DRS.
"As a racer, I'm happy about anything that gives us better opportunities for overtaking," he said. "If the system works well it's no doubt a great idea. I'm also sure that the fans will love it."
Also due for a final evaluation at the upcoming test is Hankook's latest-specification of a Formula 1-style option tire. Both new ideas would likely be introduced in 2014 if there is not deemed to be sufficient time to implement their effective uses this year.
