Red Bull attack Ferrari's DRS system

Red Bull now suspect Ferrari’s DRS is illegal claiming it opens wider than the allowed 6.5cm. It’s the fourth item on the Ferrari car which has attracted attention this season.

After Barcelona, the Italians had to remove ‘Halo winglets’ from the car in their innovative design to hand mirrors from the halo.

Their oil consumption came under the attention when Mercedes claims smoke fills their garage when Ferrari start-up. And most recently in Monaco, the FIA ran checks on a double battery system.

Charlie Whiting said more checks may be needed in Canada.
