Audi once again had the better of Mercedes in the DTM, with Martin Tomczyk leading home a 1-2-3-4 for the manufacturer at the Nurburgring, scoring his first win since the 2007 race at the track. Title rivals Timo Scheider and Mattias Ekstrom finished second and third, with Mercedes main title hope Gary Paffett only eighth.
Jules Bianchi extended his Formula 3 Euro Series Saturday race winning streak to five with a crushing display over his ART team-mates at the Nurburging. Then Briton Alexander Sims scored his first win in the championship in Sunday's reverse grid encounter, leading home Mucke Motorsport team-mate Christian Vietoris.
Meanwhile, British F3 rivals Daniel Ricciardo and Renger van der Zande took a victory each on the Silverstone International circuit, both charging well clear of their pursuers. Ricciardo's main title rival Walter Grubmuller kept himself in touch with second and fourth place finishes.
Andy Soucek did his Formula 2 championship prospects no harm at all with his third win of the season at Donington Park, while his main title rival Robert Wickens failed to score. Julien Jousse stormed to his maiden victory in the second race, winning by 15 seconds.
Valentino Rossi now has one hand on the MotoGP championship crown after Jorge Lorenzo's Brno crash allowed the Italian to stretch his championship lead to a comfortable 50 points.
