Renault looks set to become a second formula one team to take the F-duct system off its car for the forthcoming Italian grand prix.

Prior to this weekend’s event in Belgium, it emerged that the technology’s pioneers McLaren were considering removing the F-duct for Monza.

On the face of it, the long straights of the Autodromo Nazionale seem perfect for the straightline speed-boosting device.

But in fact, the ultra-low downforce nature of the circuit means a lighter, sleeker and more efficient rear wing and engine cover might prove the better option.

Renault finally brought its F-duct to the R30 for this weekend’s Spa-Francorchamps event, where Robert Kubica was a standout performer.

He said the F-duct worked “very well” throughout the weekend.

But after finishing second on Sunday, he said: “Monza will be quite a tricky race.  It is a completely different downforce level track and I most probably will not have the F-duct there.”

Interestingly, the Pole also said the F-duct will probably not be fitted to the car for the subsequent Singapore street race — perhaps because the layout does not feature enough straights.

“Singapore should be a good one for us,” said Kubica.  “It is good track for us but most probably we won’t have the F-duct there unfortunately.”

Meanwhile, McLaren is not confirming whether its F-duct will definitely be removed from the MP4-25 for Monza.

“I don’t see any merit in us declaring to our competitors what we are going to do before we get there,” said team boss Martin Whitmarsh.

Timo Glock has joined a group of F1 drivers who think the ‘proximity’ wing idea is a bad one.

FOTA chairman Martin Whitmarsh has admitted that the proposal, with chasing drivers able to press a button and boost straightline speed next season, might not see the light of day.

“I think it’s highly dangerous,” Glock is quoted as saying by the website of the Swiss publication Motorsport Aktuell.

“From the viewpoint of safety, I think it’s a wrong decision.”

The speed difference between the Lotus and Red Bull cars was arguably the cause of last Sunday’s huge crash at Valencia involving Mark Webber.

“We’ve seen what can happen if the guy behind has significantly more speed,” Virgin driver Glock said.

“Mark was just lucky that there was enough run-off and he could just run into the tyre barrier,” added the German, suggesting that the return of KERS in 2011 could boost the speed differences even more.

“The drivers all have the same opinion; it is clearly too dangerous,” said Glock of the adjustable rear wing idea.

“Perhaps the (GPDA) drivers’ union can do something.  It should definitely be talked about.”

Jun.16 (GMM)  Robert Kubica is the first formula one personality to oppose plans for ‘proximity wings’ in 2011.

After a meeting in Canada last weekend, teams agreed that drivers should next year be able to adjust their rear wings when they are following a car, in order to boost their chances of overtaking.

“I think that could be quite exciting,” said FOTA chairman Martin Whitmarsh, insisting that drivers will not be able to use the straightline speed-boosting system to defend position.

FOTA’s technical chairman Ross Brawn added: “It’s going to be an enhanced F-duct, where the car that is following will be allowed to reduce its drag to attack the car in front.

“I think that will give a lot more opportunity for overtaking.”

But Renault driver Kubica insists that grands prix have been exciting enough in 2010 without the radical innovation.

“And secondly,” he told Germany’s Auto Motor und Sport, “why it is only now that people are noticing that overtaking is difficult?

“I watched my first formula one race in 1997, and there was not much overtaking then,” noted the Pole.

Red Bull might not test its new F-duct system on the long straights of Montreal’s Circuit Gilles Villeneuve next Friday.

The team took its initial version of the downforce-stalling concept off the RB6 after Friday practice in Turkey, after Sebastian Vettel reported that it had not functioned perfectly.

“We need to work on getting the right effect,” said the German.

It had been expected that the team would test the innovation again during Friday practice in Canada, where the straightline speed boost will be a big advantage on the fast layout.

But on Austrian television ‘Sport und Talk aus dem Hangar 7′ on Tuesday, Red Bull advisor Helmut Marko indicated that the F-duct will not be used in Montreal next week.

“It did not work perfectly,” he confirmed on Tuesday, referring to the Istanbul Park test.

“Therefore, we are developing it further.  We will bring it again to Valencia,” he added.

With the Red Bull-fight raging, it is easy to overlook that the whole episode was triggered by the major step forward made by McLaren in Turkey.

The entire F1 paddock had predicted another race of utter dominance from the energy drinks-owned team.

But although Mark Webber and Sebastian Vettel were leading at Istanbul Park, it was the pressure applied by the chasing Lewis Hamilton and Jenson Button that revved up the urgency of Vettel’s ill-fated overtaking move.

“We were quicker than the Red Bulls,” said Button.  “It’s amazing how much of a leap we’ve made.  We’ve bridged the gap and the rest have stayed back.”

It is suggested that the success of McLaren’s F-duct on the long straights of Turkey has clouded the overall improvement to the MP4-25 car.

Red Bull tested its own version of the straightline speed-boosting innovation in Istanbul, and will test it again on Friday in Canada after the team decided not to qualify or race with the immature system.

Red Bull boss Christian Horner is busily sorting out the internal teammate crisis at present, but he is also expecting another hard fight from McLaren at the forthcoming races.

“We’ll bounce back in Montreal and Valencia, but those are two tracks that are going to play to (McLaren’s) straightline advantage,” he admitted.

Joan Villadelprat wrote in his latest column for El Pais newspaper: “The Mercedes engine, the most powerful on the grid, is another element playing in the favour of McLaren.”

And Ferrari test driver Marc Gene wrote in El Mundo: “We must applaud the British team.  They did a great race and the one-two was no accident.

“Their improvement has been remarkable and their jump has surprised everybody.”

Cosworth is not in Rubens Barrichello or Lucas di Grassi’s good books at the scene of the Turkish grand prix.

Williams’ Rubens Barrichello, just fifteenth on the grid at Istanbul Park, said the British team is “suffering” from a lack of power.

“The engine that we brought did not work,” he is quoted by Brazil’s Globo.  “The straightline speed is not good.”

Lucas di Grassi is also unhappy, having been outqualified by Bruno Senna of the struggling HRT team.

“My lap was good,” said the rookie, who is finally at the wheel of Virgin’s updated VR-01 car this weekend.

“The car was good in the corners, but the engine was not working on the straights or in acceleration.”

Di Grassi will have a fresh engine fitted for Sunday’s race.

Lewis Hamilton on Monday admitted he is worried about Red Bull’s plans to introduce an F-duct this weekend in Turkey.

The downforce spoiling concept was pioneered this year by McLaren, but key rivals including Ferrari and Mercedes have steadily followed suit.

The system promises a straightline speed boost, which is an ominous prospect for Red Bull’s rivals, given the current dominance of the championship leading RB6 car.

“With this system the best team becomes even stronger,” 2008 world champion Hamilton is quoted by Germany’s Sport Bild.

“The RB6 has many good, detailed solutions. I have already told my engineers that we must copy them,” added the Briton.

A written plea by McLaren did not convince the British team’s rivals that controversial ‘F-duct’ innovations should be allowed to stay in F1 in 2011.

During a team meeting last weekend in Barcelona, a majority of the bosses voted for a rule tweak that will outlaw the controversial downforce-stalling solutions for next year.

After McLaren invented the straightline speed boosting concept this season, teams including Sauber, Ferrari, Williams and Mercedes have experimented with their own versions.

It is also believed that Red Bull, Renault and Force India are working on the concept at their respective factories.

But Red Bull’s Christian Horner indicated that the vote against F-ducts for 2011 was influenced by the marginal safety of the systems seen in Spain last weekend.

Both the Sauber and Ferrari drivers were activating the airflow with one of their hands, often out of high speed corners like Barcelona’s turn 3, while simultaneously fidgeting with other controls including brake balance.

“It’s a clever piece of engineering and hats off to the guys who invented it, but some of the solutions this weekend look a little bit marginal when you see drivers driving with no hands basically,” Horner is quoted as saying by the BBC.

“So I think there is a safety issue and a cost issue to take into account,” he added.

(GMM) After finished last GP, Back at Maranello, Ferrari is hard at work to emulate the success of McLaren’s so-called ‘F-duct’ downforce-spoiling innovation.

On the British team’s 2010 car, the once-controversial solution – with the drivers controlling a flow of air through to the rear wing with their left knee – passed scrutineering at the Bahrain season opener.

At the next race in Melbourne, Sauber’s similar system made its first appearance, amid reports that Red Bull, Force India, Williams and Mercedes were also working on F-ducts at their respective factories.

Ferrari team boss Stefano Domenicali said after Sunday’s Malaysian grand prix that Ferrari is also working on a version for the F10.

“We have seen that the advantage (of the system) is very, very big,” said the Italian, referring to the straightline speed advantage enjoyed by McLaren’s Lewis Hamilton and Jenson Button.

“We will bring it to the races as soon as possible, once we are sure that it is 100 per cent,” added Domenicali.
