Despite not topping a Friday timesheet in Barcelona, one specialist publication sees Lotus as the favourite for Spanish grand prix victory.

Germany’s Auto Motor und Sport said the ‘long run’ pace of the black and gold E20 was studied carefully after Barcelona practice.

“Kimi Raikkonen made a great impression on the critical soft tyres,” the report read.

“First, it (the field) is incredibly close. Second, Lotus could win its first grand prix here.”

If true, the former Renault team would become the fifth different winning constructor in the opening five races of the extraordinary 2012 season.

“Our biggest opponent for Sunday is not Red Bull,” an unnamed McLaren engineer is quoted as saying. “It’s Lotus.”

And another surprise pacesetter is Sauber. “Over 15 laps we were better than Red Bull,” team manager Beat Zehnder enthused.

“If everything goes right, we can be on the podium,” he is quoted by the Swiss newspaper Blick.

Agreed McLaren’s Jenson Button: “The Lotus, Sauber and Williams look very strong.”

But in reality, in F1′s new guise of 2012, no one knows what is going to happen on Saturday and Sunday.

“Lord knows what will happen here tomorrow,” wrote The Times’ Kevin Eason. “Well, perhaps He is the only one who does know what is going on — F1 hasn’t a clue.”

A third team has decided to join Red Bull in Abu Dhabi for the young drivers’ test.

Due to the calendar congestion at the end of this season, and also to cut costs, most teams have opted to drop the Abu Dhabi option in favour of testing young drivers in July, at Silverstone.

But Red Bull, and its second team Toro Rosso, are sticking with the original November plan, amid criticism July is too early to be assessing young drivers.

McLaren is now following suit.

“Our plan at McLaren at the moment is to test in Abu Dhabi,” said the British team’s sporting director Sam Michael, who said another factor against Silverstone is that teams are only half-way through their engine mileage allocations in July.

“Engines is a significant factor,” the Australian explained.

“If you want to test at the end of the year, you have so many part-mileage engines that all have a little bit of mileage on them so you can effectively do it for free, in terms of your race engines,” said Michael.

“If you try and do that in the middle of the year, you can’t use your race engines so you have to prepare a special test engine.”

Lotus is the “biggest surprise” of the 2012 season so far, Red Bull’s team owner Dietrich Mateschitz has admitted.

In an interview with Austria’s Salzburger Nachrichten newspaper, the billionaire mogul was mildly critical of the “lottery” that is this year’s championship, with Pirelli’s unpredictable tyres setting the scene.

“That is going to continue,” Mateschitz said.

“Then it will gradually turn into a duel between McLaren and Red Bull Racing,” he predicted.

“Mercedes are still not able to keep doing in the race what they are doing in qualifying. So we are not convinced of their F-duct (double DRS) system and we won’t try to copy it.

“Ferrari needs to try the hardest to catch up. And Lotus are the big surprise for me,” he insisted.

Monisha Kaltenborn has revealed she has “very big plans” for Sauber.

Named by founder and team principal Peter Sauber as his forthcoming successor, the 41-year-old Indian is in effect already leading the Swiss team at grands prix.

She will take over in earnest at some point in the foreseeable future, thus officially becoming the first female team principal in the sport’s history.

“I have very big plans for the team,” she told the APA news agency in Barcelona.

“I am very happy with the trust that has been put in me,” Kaltenborn, whose current title is chief executive officer, added.

She said she is not bothered that she is not yet the team boss in title.

“For me, it’s never been important,” said the lawyer. “There are more important things.”

Stefano Domenicali has ruled out responding to Ferrari’s latest crisis with the old ‘rolling heads’ technique.

One perception in the paddock is that the fabled Italian team, under intense pressure from the Tifosi and president Luca di Montezemolo, often reacts by emotionally shedding staff, with Aldo Costa and Chris Dyer the obvious recent examples.

So, having installed new faces including Pat Fry but still struggling with the latest F2012 project, will boss Domenicali set heads rolling again?

“Firing people is the work of two minutes,” he is quoted by Germany’s Auto Bild, “but this would not solve our problem.

“Instead I need to find new people who can improve the organisation and push the engineers to improve the car,” added the Italian.

In the meantime, there is no silver bullet.

“I am not happy with the F2012 project,” he acknowledged.

“But if you want to see the glass half full rather than half empty, then Fernando has done a great damage control and, with an improved car, he at least has the possibility to continue to fight for the championship.

“We have to improve,” Domenicali insisted. “I have asked my people to wake up and respond, and I will no longer hear excuses.”

A lack of official information has triggered speculation about Ross Brawn’s health.

And another rumour is that his absence in Barcelona could be connected with Mercedes’ billion-dollar dispute with Bernie Ecclestone over the next Concorde Agreement.

The German squad announced on Thursday that Bob Bell is leading the team in Barcelona because regular boss Brawn is back in Britain on doctor’s orders.

Bild newspaper said the 57-year-old was given the advice in hospital earlier this week, following a dizzy spell at his home in England.

“It’s more than the flu,” chief executive Nick Fry is quoted as saying, “but I can assure you that it’s nothing life threatening.”

Indeed, a spokeswoman told us on Thursday that Brawn will be back to work at Monaco in a fortnight.

For Spain, Brawn will watch the action on television.

“We will still keep in touch,” Michael Schumacher revealed. “Ross cannot be replaced. That’s simply impossible.”

McLaren has made changes to its pit crew and processes, following recurring problems at recent grands prix.

Team boss Martin Whitmarsh launched a full internal investigation after Bahrain, where problems with the fitting of wheels during crucial stops resurfaced.

“We have to try and make sure we pick up on them (the problems) for the next race because we can’t afford to lose points like we did,” said Lewis Hamilton.

One wheel-gun operator got the lion’s share of the blame, but Whitmarsh insisted that McLaren would also “look at the equipment, the process, the approach”.

He told reporters on Wednesday: “We have looked at what we are doing and have made some changes to the team and the process and we’ll see them on Sunday in Barcelona.”

Despite the heat felt by the deposed wheel-gun operator, Whitmarsh reveals he was “astounded” by the number of McLaren mechanics who put their hands up to replace him.

“It reflects well on the spirit of the team. There’s been a reasonable amount of practice and we’ll see at the weekend. I believe we’ll have good stops,” he concluded.

It is too early to name a frontrunner for a seat at Red Bull’s premier team.

That is the claim of Franz Tost, the boss of the energy drink company’s junior team Toro Rosso.

Following the ousting of Jaime Alguersuari and Sebastien Buemi, the Faenza based outfit has two new Red Bull youngsters to groom in 2012.

Daniel Ricciardo and Jean-Eric Vergne are therefore at the front of the queue to potentially replace Mark Webber at the senior team, even though Red Bull chiefs have appeared to indicate that Australian Webber is staying put for now.

So when asked by Austria’s Laola1 whether Ricciardo or Vergne are winning the race to Red Bull Racing so far, Tost insisted: “We have no thoughts about that.

“The important thing is that they continue to develop in every area.”

So far, Frenchman Vergne has four points compared with Ricciardo’s two.

“Jean-Eric is willing to take more risks,” Tost admitted, “while Daniel has a grasp of the car overall with his extra experience.”

McLaren looks set to run a higher nose this weekend in Spain.

Last week, at the very end of the Mugello test, test driver Oliver Turvey debuted a new front wing that featured a conspicuously higher nose tip.

McLaren, the early 2012 frontrunner but having struggled recently in Bahrain, was the only notable team this year to ignore the new design trend for ugly ‘stepped’ front noses, introduced as arguably the best solution to new nose-height safety regulations.

The MP4-27′s new nose does not feature a step element, but the tip is notably higher than its predecessor.

“Nowadays it is quite a critical part of the car, you’re looking to find very small improvements,” team boss Martin Whitmarsh said on Wednesday.

As for whether the new nose will be seen in Barcelona, he confirmed: “You may well see it again, yes.

“There’s a reasonable chance you’ll see it on Sunday.”

Mark Webber appears headed for a new contract with Red Bull, after receiving a clear vote of confidence from the energy drink company’s chief.

Following speculation the 35-year-old Australian could be headed to Ferrari in 2013, Red Bull team boss Christian Horner insisted Webber “is happy to be here, and we are happy to have him with us”.

And the Swiss newspaper Blick has revealed that team owner Dietrich Mateschitz, the billionaire mogul, is also happy with Webber.

“I hope that he keeps driving with us for a long time,” the 68-year-old is quoted as saying.

Ferrari’s title tilt could hinge on the competitiveness of the updated F2012 this weekend in Barcelona.

“What I want is to have a competitive car in Barcelona,” insisted the famous Italian marque’s president Luca di Montezemolo on Tuesday.

“That’s what I’ve asked for,” he is quoted as saying by Brazil’s O Estado de S.Paulo newspaper.

Ferrari had congregated at its Fiorano test track, to watch Jacques Villeneuve drive the 1979 single seater to mark the 30th anniversary of his father Gilles’ fatal crash.

But Montezemolo’s disappointment is with the latest Ferrari, which has been heavily updated since the Bahrain grand prix three weeks ago.

“Our technicians are confident, but we will have to see how our opponents have advanced too,” he added.

O Estado de S.Paulo correspondent Livio Oricchio claimed “Montezemolo knows” that anything other than a big step forward in Barcelona will mean Ferrari has to “start thinking about” its 2013 project instead.

“Now we have to make a quantum leap, to have a car that is more competitive, less difficult to drive, and gives confidence to the fans,” Montezemolo is quoted by La Stampa newspaper.

“Let’s see how it goes in Spain,” he told Rai television.

“I have asked for an extraordinary response from our engineers,” Montezemolo is also quoted as saying by Italy’s Sky Sport 24.

La Gazzetta dello Sport, meanwhile, quoted lead driver Fernando Alonso as saying: “Our goal is to be world champions in November, and if we are to succeed then we must do better than we have done so far.”

Team boss Stefano Domenicali agreed: “We expect a significant evolution that will bring us closer to the step we need.

“The Spanish grand prix is definitely open, as is the championship. I say this because we believe.”

Getting the setup right is a challenge teams are grappling with in 2012.

So far this season, four different cars have won the four grands prix, with Pirelli’s difficult tyres credited or blamed for the unbalance of power.

The key, according to Mercedes team boss Ross Brawn, is car setup.

“We can’t modify the setup between qualifying on Saturday and the race on Sunday,” he is quoted by Brazil’s O Estado de S.Paulo newspaper. “And they are very different challenges, especially with this year’s tyres.

“It’s one thing to get the car to be fast on one lap and quite another to make it fast and consistent over 70.

“Whoever can anticipate what will be required for the race and come to a compromise – maybe to the detriment of grid position – should have a decisive advantage in the race.

“But it’s not easy to anticipate what happens on Sunday,” insisted Brawn.

Red Bull’s team boss has moved to ease speculation Mark Webber could be set to change teams at the end of 2012.

The 35-year-old Australian is now on only a one-year contract, triggering reports he has been lined up by Ferrari as a potential successor to the struggling Felipe Massa.

But subsequent speculation said Red Bull is in fact close to offering to extend Webber’s deal.

Team boss Christian Horner ridiculed the Ferrari rumours.

“I think it’s inevitable,” he is quoted by France’s L’Equipe. “Almost every driver in the paddock is supposed to be joining Fernando Alonso next season.

“We’re staying focused on ourselves. Mark is happy to be here, and we are happy to have him with us,” said Horner.

“When the time comes later this year, we will sit down and discuss the future with him, as we have done in previous seasons.

“Speculation like this is part of the business,” he insisted.

“Mark has driven very well in these first few races, finishing fourth four times. Of course we would like to see him on the podium but he has scored some very important points.

“He can do great things this year. I think with Sebastian (Vettel), they push each other — it’s also thanks to him (Webber) that Sebastian gives the very best of himself.

“There is a good dynamic between them and that’s exactly what we want,” Horner said.

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.

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.
