The DTM has revealed all the details of the two-race format per weekend that returns to the series this year.
The move to go back to two races per weekend, a format used in the championship until 2002, was announced in December last year.
All of this year's events will feature a race on Saturday and another on Sunday, with championship points being awarded in both.
Drivers will contest a 20-minute qualifying session both days.
There will be differences between the Saturday and Sunday races in the pitstops and the length of the races.
The Saturday race will be 40 minutes and a full lap, with no mandatory tyre changes.
Sunday's race will be 60 minutes and a full lap long, but will feature a mandatory pitstop for new tyres.
"With two championship rounds per weekend we provide the spectators twice as much of the things that count: more door-to-door battles, more thrilling decisions, and more fascinating motor racing," said series boss Hans Werner Aufrecht.
"And we are convinced that the differing race formats will make for entertaining and thrilling races."
The 2015 season kicks off at Hockenheim on April 30.
