McLaren tested a higher front nose at the Mugello test last week.

Backmarker Marussia aside, the famous British team is the only team in 2012 to have resisted the temptation of running a high ‘step’ nose, in the wake of new safety regulations.

McLaren was the early frontrunner this season with its MP4-27 car, but Jenson Button and Lewis Hamilton struggled notably last time out in Bahrain.

Germany’s Auto Motor und Sport said the team quietly tested the significant nose development on the final day of Mugello testing last Thursday, with test driver Oliver Turvey at the wheel.

The report also speculated that McLaren experimented with an adjustable brake duct system at Mugello, which might be used to regulate tyre temperature for the finicky 2012 Pirellis.

The system would have to be adjusted by the mechanics during a pitstop.

Mark Webber has hit out at F1 rival Vitaly Petrov.

Last week, as the sport tested at Mugello, Russian driver Petrov suggested the high speed Ferrari-owned layout is too dangerous for modern grand prix cars.

“You get very close to the walls and it’s maybe a bit small for the cars now,” said the Caterham driver.

Australian Webber, however, had raved about Mugello, likening 10 laps there as akin to 1000 tours of Abu Dhabi’s heavily-criticised Yas Marina layout.

Posting a photo on Twitter of Jim Clark driving unprotected past houses at the Aintree circuit in 1962, Webber remarked: “I wonder if V Petrov was there”.

Norbert Haug has denied reports Mercedes is on the verge of quitting F1.

London newspaper The Times’ F1 correspondent Kevin Eason reported that the German carmaker has conducted a study into how the withdrawal could be effected.

He said the reason for Mercedes pulling out would be because, unlike Ferrari, McLaren and Red Bull, the Stuttgart marque has not been offered a place on F1′s post-floatation board.

When asked about Eason’s report, Mercedes’ competition vice-president Haug insisted to Germany’s Auto Motor und Sport: “There is absolutely no truth to that.”

The report said negotiations between Mercedes and F1 bosses over the next Concorde Agreement are ongoing.

First as an engine supplier only, Mercedes has been in F1 in the modern era since 1993.

The Spanish windscreen repair and replacement company and HRT Formula 1 Team have signed a collaboration deal for Cristalbox to become a new sponsor of the Spanish outfit for 2012. Cristalbox, who have already been linked with the motorsport world for a few years, have decided to extend this link and have taken a step into Formula 1 alongside HRT Formula 1 Team, with the objective of supporting the Spanish team’s project in the pinnacle of world motorsport.

The deal with which Cristalbox joins the team as a sponsor has a one year duration and the glass repair company has bolstered its commitment to HRT’s project by completing a spectacular glazing job at the new Caja Mágica headquarters in Madrid. The creation of a curtain wall at the team’s workshop supposed the installation of more than 25,000 kilogrammes of specially fabricated glass and will enable the team to make the most of the sunlight and environmental conditions.

Just like the conditioning of the other project areas at the Caja Mágica facilities, the installation and reinforcement of the curtain wall has been completed in under a month, thus proving the capacity of the Spanish company to expand its services.

Javier Celaya, Cristalbox General Manager: “A passion for cars is in the genes, the DNA, of our brand and top level competition reflects the essence of Cristalbox’s values: precision, speed, safety, resistance, reliability…From an advertising point of view, after two years sponsoring Formula 1 broadcasts, this was the logical evolution: to form a part of the competition. With HRT we can support a credible Spanish project in the pinnacle of motorsport and strengthen the reach of our brand to our targets”.

Luis Pérez-Sala, HRT Team Principal: “Formula 1 is all about technology and speed, two basic principles which we share with Cristalbox. They are a leading company in our country and we’re proud that they decided to fully submerge in Formula 1 alongside us and fully back our project. I want to thank them for the trust they have put in us and also for the extraordinary efficiency with which they have completed the structure and glazing of the workshop area in our new headquarters at the Caja Mágica. It was a structural and temporal task and they passed it with flying colours. We hope to overcome many other tasks alongside them this year”.

Carlos Sainz jr is on course for a future in formula one.

The 17-year-old Spaniard is the son of Carlos Sainz, the former two-time world rally champion.

Sainz jr, however, has pursued a career in open wheelers, and – now that Daniel Ricciardo and Jean-Eric Vergne have stepped up – he is the new cream of energy drink Red Bull’s junior driver programme.

And another direct link to the world of formula one for Sainz jr is his new sponsorship deal with Cepsa, the Spanish oil company that is also Red Bull-owned Toro Rosso’s main backer.

Sainz jr’s new Cepsa deal is for his participation this year in the British and Euroseries F3 categories, but “Our intention is to continue (beyond 2012),” Cepsa co-chairman Santiago Bergareche is quoted by Marca newspaper.

“Hopefully everything goes well and Carlos will be in that world (F1) one day,” added Cepsa chairman Alfonso Escamez.

He said the deal does not guarantee Sainz jr a future in f1.

“The sponsors have no say on the teams of the drivers. We can try to influence, to give our opinion, but we are not (able to decide) on that side.

“We hope that it does happen, but it will not necessarily.”

Mercedes is “on the verge” of quitting formula one.

That is the alarming claim of the London newspaper The Times, in an article written by its authoritative F1 correspondent Kevin Eason.

Eason wrote that while rival top teams Ferrari, McLaren and Red Bull will get to appoint directors once F1 is floated on the Singapore exchange, Mercedes has not been extended the same offer.

“Why should Mercedes have the same deal as the others?” F1 chief executive Bernie Ecclestone is quoted as saying. “What have they done in formula one?

“They won a race and that is it.”

That attitude, Eason argues, has left Mercedes “on the verge of quitting formula one”, having apparently conducted a study into how its Brackley based works team could be withdrawn.

Eason also quoted Ecclestone as having “scoffed” at the suggestion Mercedes quitting could wipe 20 per cent off the value of F1′s stock market floatation.

Red Bull’s two teams look set to test alone in Abu Dhabi later this season.

Until recently, the now-traditional young drivers’ test – giving inexperienced drivers the chance to drive current F1 cars amid the sport’s strict testing limits – was scheduled to take place as per usual at the Yas Marina circuit in November.

But those plans were reconsidered due to this year’s congested calendar.

India takes place just one week before Abu Dhabi, the young driver test is scheduled for the week after and then the races in the US and Brazil happening back-to-back next.

In the light of that arduous schedule, Reports in March said the teams were keener on having the young driver test at Silverstone.

“It’s a long season as it is and there are a lot of back-to-back races this year, so it’s tough for them (the teams),” Abu Dhabi circuit boss Richard Cregan conceded.

The German-language Speed Week reports in its May 2 edition that the majority of teams want to test instead at Silverstone, in July.

But the magazine said Red Bull’s two teams – Red Bull Racing and Toro Rosso – are sticking with the original Abu Dhabi plan.

The report also said other teams might cancel Silverstone at the last minute and join Red Bull in Abu Dhabi, should weather reports indicate the British weather would likely affect the July test.

Food giant Nestle’s boss has confirmed he is set to enter the world of formula one.

Austrian businessman Peter Brabeck-Letmathe confirmed to Kleine Zeitung newspaper that he has been lined up to chair the sport’s parent company once it has floated on the Singapore exchange.

“That’s right,” said the 67-year-old.

“And it’s true that I have agreed to take over the chairmanship of the supervisory board in a non-executive function.

“If formula one is to be a public company then it is important that the chairman is independent.”

Brabeck-Letmathe confirmed that Bernie Ecclestone, 82, is remaining F1′s chief executive.

“We certainly hope that Bernie stays healthy for a long time and can keep on working,” he said.

“I am already impressed with his performance. But of course it is the task of a supervisory board to ensure the succession of a business.

“At Nestle, I have always ensured that everyone can be replaced from the executive board within 24 hours. So we need to think about how to replace Bernie Ecclestone as well.”

Rubens Barrichello is still refusing to give up on his formula one career.

After a record-setting 19 consecutive seasons on the grid, the 39-year-old Brazilian lost his Williams race seat for 2012 and switched to the premier American open-wheeler series, Indycar.

“I’m enjoying it,” insisted Barrichello to O Estado de S.Paulo newspaper.

“I have been welcomed and the feeling is a much more open one.

“But the fact that I keep active and am competing is, for me, still a way to be seen and to attract the eye of formula one.

“For all that I did in F1, I would be able to go back there,” added the former Ferrari and Honda driver.

Michael Schumacher’s brother has tipped the seven time world champion to keep racing beyond his 44th birthday.

Schumacher’s Mercedes deal runs out this year, but talks about a new contract for 2013 are yet to be discussed.

Ralf Schumacher, also a grand prix winner and six years younger than his more famous sibling, was asked by Bild am Sonntag newspaper about Michael’s recent anti-Pirelli outburst.

Asked if it was an overreaction to the fact his teammate Nico Rosberg was the first Mercedes driver to win in 2012, Ralf answered: “It has nothing to do with it.

“But for sure Michael came back to celebrate successes with Mercedes. And until he succeeds, he will not give up.

“I still see a lot of fire in Michael,” said Ralf Schumacher, now a DTM driver with Mercedes.

“He is pushing hard, as we saw as recently as Mugello last week.”

Ralf said Mercedes’ 2012 F1 car, the W03, is well built.

“I think we will see Michael on the podium soon,” he insisted.

“At some point, there surely comes a point when the body can’t do it any more. But when I look at Michael, that’s still a few years away.

“I certainly won’t be racing as long as he has,” he laughed.

Mark Webber’s future in formula one seems secure, after reports this week linked him to two top teams for the 2013 season.

First, Spanish specialist reports said Ferrari is interested in the experienced Australian to replace struggling Felipe Massa next season.

And now, the Australian Sydney Morning Herald newspaper claims Red Bull, 35-year-old Webber’s current team, is “all but ready” to extend his contract through 2013.

That would give junior team Toro Rosso’s Daniel Ricciardo and Jean-Eric Vergne, tipped to eventually replace Webber, “a further season to adjust to the category and prove themselves worthy of the top drive”, the report added.

Whatever top team he is in, Webber confirmed he is not ready to retire.

“I’m really enjoying my driving and clearly I’m off to a really good start this year,” he said.

“I feel completely reinvigorated and am just really enjoying it, which has been reflected in my driving and my results.

“So I’ll keep pressing on. Retirement isn’t even on my radar at the moment. The results are there and when they are there I keep driving,” added Webber.

After Sebastian Vettel’s first win of the season in Bahrain recently, Red Bull could now maintain its grip on 2012.

That is the claim of the legendary triple world champion Niki Lauda.

Red Bull has been the dominant force since late 2009 and 2010, and Vettel was untouchable last year as he successfully defended his drivers’ championship breakthrough.

But four different teams have won so far in 2012, and only the last of them were Red Bull and Vettel, as the energy drink-owned team’s superiority appeared to have waned.

After Bahrain, however, Red Bull and Vettel are back, Lauda told Germany’s Auto Bild Motorsport.

“In Bahrain, they got the car and the tyres right for the first time, and they won,” said the Austrian.

“They will have improved the car further in Mugello, so I see enormous potential for another dominant season,” he added.

Lauda acknowledged that the blown diffusers of the past seasons was Red Bull’s “great strength”, and now that is gone.

“Nevertheless, Red Bull is the team to beat,” he insisted.

Ferrari might be gearing up to incorporate a ‘double-DRS’ setup aboard its improving F2012 car.

If true, the famous Italian team would be the first team to successfully emulate the controversial Mercedes system, which has been declared fully legal by the governing FIA.

Germany’s Auto Motor und Sport said a new rear wing was among the very last upgrades to be trialled by Fernando Alonso as the Mugello test concluded late on Thursday.

“The wing has only minor changes. You have to look closely,” read the report.

The magazine reported rumours that the wing might eventually accommodate the so-called ‘double-DRS’ or 2012-style F-duct, which would work in conjunction with a new and so far unseen front wing.

“That (wing) will debut along with a new diffuser and nose in Barcelona,” added Auto Motor und Sport.

There were happy faces in the Ferrari garage on Thursday, as – despite a minor off by Alonso – the upgrades appeared to work well.

“Barcelona will be a key moment in the season, but not a decisive one,” the Spanish driver insisted.

“It’s not a case that we will suddenly find ourselves back on pole position, because there is no magic button.”

Echoing the earlier words of Mark Webber, Alonso said the “fastest car” at Mugello this week was the Lotus.

Red Bull’s Dr Helmut Marko agrees: “It looks like Lotus are the quickest.”

Veteran Swiss correspondent Roger Benoit wrote in Blick newspaper: “Lotus, with Kimi Raikkonen in super shape, is the championship dark horse.”

Tony Fernandes has admitted he would have liked corporate Malaysia to have backed his formula one team.

The Malaysian entrepreneur founded a UK based start-up team in 2010, calling it Team Lotus before a bitter spat developed with the Lotus name’s owner Proton.

“While I was building a formula one team, I was being sued by my own countrymen,” he told The Star newspaper.

“We’re the only true formula one team developed in Malaysia.”

Now called Caterham, the team’s only Malaysian sponsorship is from AirAsia — Fernandes’ own low-cost airline.

“Never mind that we were not sponsored (by Malaysia), that’s a company’s prerogative,” he said. “But, we were sued.”

Some have accused Caterham of not having progressed much since 2010, but Fernandes strongly disagrees.

“Two years ago we had nothing. We’re now 1.5 seconds away from Red Bull who are the world champions. We’re closing the gap.

“You can’t build Rome in a day,” he insisted.

Sebastian Vettel has hit back at what he thinks was an “exaggerated” reaction to Michael Schumacher after the recent Bahrain grand prix.

Schumacher, Vettel’s countryman and friend, had heavily criticised the sport’s official supplier Pirelli, despite the Italian marque’s 2012 tyres being widely credited for the exciting grands prix seen so far this year.

“It’s been a bit exaggerated,” world champion Vettel, referring to the reaction to Schumacher’s comments, is quoted by Sport Bild.

“Ultimately, we all have the same tyres, but of course as a driver you always want more grip, whether from the tyres or from the car.

“It is in our nature to want more — more especially than the others,” he smiled.

“When I talk about this with Michael, it’s not so dramatic. He has been around for a long time and has seen a lot, also when it comes to tyres.

“I don’t think he is so easily shocked,” insisted Vettel.
