Vettel may need to change gearbox in Austria

Sebastian Vettel is likely to be hit with a five-place penalty due to a gearbox change at this weekend's Austrian Grand Prix, serving a blow to Ferrari who have yet to win a race so far this season

Although yet to be confirmed, Ferrari will see through the first two practice sessions at Red Bull Ring before making a final decision, and should they opt to change the gearbox it will surely compromise Vettel's grand prix weekend, at a venue where Ferrari are expected to perform well.

This would result in a five-place grid penalty for the German who is 21 points adrift of second placed Lewis Hamilton, with the other Mercedes driver Nico Rosberg topping the standings.
