The DTM will run on a shortened Hockenheim layout when the series visits the German Grand Prix venue for the second time this season, on Oct. 16-17.
In a bid to increase the number of laps the cars complete during the race, the DTM's organizers the ITR have agreed with the track owners to cap the hairpin and instead introduce two right-hand turns that will take the cars into the stadium section some 400 meters earlier.
Work on the track, which requires approval from the German motorsports authority DMSB, will mean the length of the lap decreases by 20 percent.
The move is not unusual for the DTM, which also uses the Brands Hatch Indy circuit and a shortened version of the Nurburgring so that fans are guaranteed to see the cars more often.
