no shark fin for McLaren or Toyota at the GermanGP
McLaren have decided against introducing their shark fin engine cover at the German Grand Prix, autosport.com has learned, despite some encouraging results in last week's Hockenheim test.
The Woking-based team experimented with the new cover as part of their build-up to this weekend's race, with Lewis Hamilton topping the times as he used it alongside other aerodynamic and mechanical developments.
However, autosport.com understands that McLaren want to run the fin in further tests before committing to using it at a race weekend. With further evaluation not possible prior to Hockenheim, the team will stick with their current design for now.
Heikki Kovalainen said after the test last week that he felt the team needed to be sure the shark fin would not be affected badly by crosswinds - something that caused Giancarlo Fisichella to crash his Force India during testing at Silverstone recently.
"Maybe Hockenheim is not the best place to try this new wing and we need to see if it is affected by crosswinds," said Kovalainen. "It was quite windy at the Hockenheim test, but we didn't seem to be too affected by the wind. It's definitely encouraging for the future."
McLaren's decision means that both the teams that tried shark fin covers out at the Hockenheim test last week have decided not to race them, with Toyota not taking theirs to the German GP either.
Toyota have opted not to run with their new shark fin engine cover at the German Grand Prix, despite testing the device at Hockenheim last week.
The Japanese car manufacturer joined McLaren in trying out the concept, which was pioneered by Red Bull Racing at the start of the season, during the pre-German GP test.
Although McLaren are still undecided about whether they will run their fin this weekend, Toyota have confirmed to autosport.com that they will not be taking theirs to Hockenheim.
That decision suggests that the wing did not bring the benefits the team had hoped, although other improvements tried out during the test have left Jarno Trulli encouraged.
"We had a promising test last week at Hockenheim which was very useful because we have not raced there for two years and we had the chance to study set-ups and tyre behaviour," said the Italian.
"That was the first time we have used the current Bridgestone Potenza tyres at Hockenheim and it was important to understand their characteristics at this circuit. We made good progress with some new aero parts and hopefully this track will suit our car.
"I have finished in the points for the last three races which shows how competitive we are at the moment, so my target this weekend is to again score points and fight for the top six. I am optimistic as usual."
Pascal Vasselon, Toyota's senior general manager chassis, believes that the team can expect a repeat of the form they showed at Magny-Cours when Trulli took a podium finish.
"We are expecting a level of performance more in keeping with our display at Magny-Cours than Silverstone," he said. "That means we are hoping to be near the front again. Actually, Magny-Cours and Hockenheim are now very similar in terms of car configuration so we are expecting to go well."
