The FIA has produced a revised calendar for the 2013 European Formula 3 championship that leaves its Norisring round clashing with the one-off F3 Masters event at Zandvoort.
Recent changes to the Formula 1 schedule led to the German Grand Prix running on the same date as the DTM's high-profile Norisring street race on July 7.
DTM organisers have moved the Norisring round back a week to July 14, which now means the supporting European F3 championship clashes with the Zandvoort Masters event.
Other changes to the F3 schedule as a result of the new DTM calendar are the championship round at Zandvoort moving from late July to late September, and the Hockenheim round moving from September to October.
