Both drivers had to tackle the Turkish Grand Prix at Istanbul Park with older wings, after their new ones were crashed in the Monaco Grand Prix. In the Principality, Hulkenberg and Barrichello both registered DNFs after hitting the barriers, therefore damaging their cars. The old wings used in Istanbul would explain the poor pace registered by the two Williams drivers last weekend.
According to the team's technical director Sam Michael, the new spec wings will improve the car's lap time by over a tenth of a second in Canada, but it will have an effect on the speed in high-speed corners, as shown in Turkey.
“Running the old front wing cost us approximately one tenth per lap, but it worked well in the high-speed corners. We will have the next evolution of the front wing on both cars in Montreal next week,” said the Williams official prior to the Canadian Grand Prix.
In addition, Barrichello will hopefully start the Montreal race with a more prepared car, as the Williams technicians are currently investigating the origins of his clutch problems in the Turkish Grand Prix. Hulkenberg's car will also be investigated clutch wise, in order for the German not to have any surprises in Canada.
“We have the clutches from both cars under investigation in the factory now to see what the problem was,” added Michael.
