The DTM will go back to a two races per weekend format in the 2015 season, organisers announced on Wednesday.
While the exact details of the format are yet to be revealed, the series has confirmed there will one race on Saturday and one on Sunday.
It will be the first time since 2002 that the DTM will use a two-race format.
The calendar will feature nine events for a total of 18 races.
"We know that many DTM enthusiasts were keen on two races per weekend as every additional race minute promises additional excitement and action," said ITR chairman Hans Werner Aufrecht.
"Now we responded to this desire and we are going to fix the details in the coming weeks."
As usual, the season will be book-ended by rounds at Hockenheim: the season opener to be held on May 1-3, and the season finale on October 16-18.
There will be four other rounds in Germany: the Lausitzring, which will switch from the second half of the season to a May date, the Norisring, Oschersleben, and the Nurburgring.
There will also be three international rounds, to be held at Zandvoort, the Red Bull Ring and Moscow Raceway.
All nine of the circuits on the 2015 calendar were used as part of 2014's 10-round calendar, with the Hungaroring missing out on a round on the new schedule.
