Ferrari’s front wing design has not yet been tested by the FIA at Spa-Francorchamps.

On Friday, the governing body – having introduced a more stringent flexibility test for the Belgian event – declared legal the wings on the McLaren as well as Red Bull’s controversial RB6.

But alongside the Red Bull accusations, there have also been suggestions the Ferrari wing has been bending too much towards the ground at recent grands prix.

“On our part we have not changed anything, we have the same parts (wings) as in Hungary,” Fernando Alonso is quoted by the Italian press.

It is understood that the FIA is planning to test the Ferrari wing at some point on Saturday or Sunday.

At the wheel of the F10, Alonso was quickest in both of Friday’s practice sessions.

“It was definitely a positive day because the car seemed to respond well in all track conditions we encountered,” said the Spaniard.

Red Bull’s car was declared legal on Friday after undergoing the latest wing and floor flexibility tests at Spa-Francorchamps.

Amid suggestions the front of the RB6 is too low at the front when at speed, the FIA ramped up the wing flexibility test for the Belgian event.

This was carried out on championship leader Mark Webber’s car, as well as the McLaren of Lewis Hamilton, after Friday practice.

The FIA confirmed that the cars’ wings and floors “were found to be in conformity” with the regulations.

“Our car has complied with the rules at every race so far and it will comply here,” team boss Christian Horner said earlier.

“We take all the talk about our car as a compliment, it shows the others don’t know what we’re up to,” he told the BBC on Friday.

The next hurdle for Red Bull will be the tougher floor tests and rules to take effect at Monza in two weeks.

Horner added: “Adrian Newey seems pretty relaxed about it.  It will only affect us as much as any of the other teams.”

Mercedes’ Ross Brawn admitted on Friday that some teams, perhaps also Ferrari, have not been happy with the recent insinuations about flexing cars.

“I know some of the teams involved were not very happy with comments I made, or McLaren made, but then I was not happy about comments they made about the double diffuser last year,” he said.

“It is the nature of formula one,” insisted Brawn.

Red Bull is using an unchanged front wing at Spa-Francorchamps, but the floor of the RB6 might soon have to be tweaked to satisfy tougher FIA scrutineering tests.

The front wing flexibility test was altered for Belgium, essentially to ensure that wings are bending downwards only in a linear fashion when weights are proportionately applied.

Red Bull boss Christian Horner said these tests had not necessitated a design change since the car dominated in Hungary, but it has emerged at Spa that the FIA also has its eye on other aspects of alleged flexing.

It is believed that the RB6 is getting its front wings so close to the ground also due to having a bendy floor.

Tweaked floor flexibility tests, and new rules stipulating the amount of breaks or joins allowed underneath the cars, will reportedly be applied as of the Italian grand prix at Monza next month.

“I cannot say whether we will be affected more or less than any other team,” said Horner on Thursday.

Germany’s Auto Motor und Sport said the existing floor tests involved applying 200 kilograms to the front of the floor, allowing flexibility of no more than 5mm.

At Monza, the new tests will reportedly involve additional loads being applied now at several locations underneath the cars.

“Webber said in an interview a couple of weeks ago that if you have a very special device on the car, people should have to build their own.

“I didn’t know they had a device on the car, so there you go,” said McLaren’s Jenson Button on Thursday.

“We’ll see what happens here, and we’ll see how their pace is compared to us,” he added.
