The strength of the BMW M4 Coupé is evident in every detail.
Montreal – Red Bull Racing were forced to make further changes to their car in the build-up to the final practice session for Sunday's Canadian Grand Prix here.
Following the controversy at the previous race in Monaco where the floor of the Red Bull car was judged to be illegal, world motorsport's governing body the FIA have ruled that the front wheel hub did not comply with Formula 1 regulations despite the design having been on the car since the start of the season.
Red Bull driver Mark Webber, who won in Monaco two weeks ago, was not happy with criticism he received regarding results achieved with an 'illegal' car.
“I'm happy to be called lots of things and I'm happy to have criticism about my driving and lots of stuff, but I will not take criticism in that respect,” he said.
“It completely pisses me off to be honest, because the car has passed every single technical regulation after the race.”
Article 3.15 in the Formula 1 Technical Regulations states “any specific part of the car influencing its aerodynamic performance” must be “rigidly secured to the entirely sprung part of the car” and must remain “immobile in relation to the sprung part of the car”.
The Milton Keynes-based team were forced to cover holes in the wheel hub which were used for cooling, as they also aided aerodynamics. – Sapa-AFP
