SPIELBERG, Austria -- Ferrari's Sebastian Vettel has questioned Formula One's decision to add an extra places for artificial overtaking devices to be used during this weekend's Austrian Grand Prix.
F1 cars are equipped with a Drag Reduction System (DRS) on the rear wing which helps give a chasing driver a speed boost at certain points on track to catch and pass a car in front. Most races feature one or two DRS zones but Austria will feature three around the short Red Bull Ring circuit -- this was also done for the season opener in Australia and June's race in Canada.
