Belgian driver Stoffel Vandoorne endured a dismal weekend in Austria which leaves Kevin Magnussen with a 30 point lead in the Formula Renault 3.5 Series.
Vandoorne suffered a water leak prior the first race at the Red Bull Ring and was subsequently forced to retire. He spun out of the second race on the first lap, while Magnussen claimed two podiums courtesy of third and second places.
Up front, no-one was able to get near Marco Sorensen. The Danish driver bounced back from an indifferent start to the season to claim a dominant pair of victories, moving up to sixth place in the championship as a result.
Red Bull young driver Antonio Felix da Costa endured a difficult weekend. Da Costa struggled due to an overheating engine in race one and limped home in seventh place. His woes continued in the second race as he was unable to get away from the grid and headed into retirement.
Nigel Melker recorded two podium places while Caterham youngster Will Stevens maintained third place in the championship with a couple of strong points finishes.
Da Costa's misfortune means he slips to fifth place in the championship, behind Melker.
Next year's potential Sauber driver, Sergey Sirotkin, retired from the opening race but made amends in the second race by storming from tenth place on the grid to fourth.
