Ross Brawn revealed on Wednesday he missed the recent Spanish grand prix to have checks on his heart.

After handing over to his Mercedes deputy Nick Fry in Barcelona, fellow Briton Brawn is back in action as the team boss in Monte Carlo.

Rumours hinted there was more to the story, but Brawn insisted to a German newspaper earlier on Wednesday that he was simply advised by doctors to take the weekend off after a night in hospital for checks.

He then told reporters in Monaco his symptoms had been “arrhythmia”, or an irregular heartbeat, insisting he is “back to normal now”.

Brawn, 57, joked the heart problem was triggered by watching an exciting football game on television.

Marussia needs a KERS system to catch up with its direct rivals.

That is the admission of team boss John Booth, who told the Russian website championat.com that he is looking into adding the energy recovery technology to next year’s Marussia package.

“First of all, I want to say that while it is said it (KERS) is a ‘green’ technology, in reality it’s just a serious waste of money,” he said.

“But in our situation it’s time to start thinking seriously about KERS. Of the gap to Caterham, five or six tenths is due to KERS,” added Booth.

“So we are thinking seriously about it for 2013, but so far there is no decision.”

Both admitted the start of the 2012 season has been a disappointment so far for Marussia, which in its first two years was called Virgin.

He said the team has recently completed a phase of serious restructuring.

“We had a good team of people before, but now we have a good team of designers. Though we have been in F1 for three years, I have the feeling that we were actually born in July 2011.”

Both is undoubtedly referring to the split mid last year with former technical chief Nick Wirth, and the relocation to a new headquarters.

Heikki Kovalainen is looking for Caterham to move into the midfield, according to his new management company.

Having handled his own career in the wake of Flavio Briatore’s demise, Finn Kovalainen recently signed up with IMG, the sports and entertainment management giant.

The 30-year-old has rebuilt his reputation since 2010 in the wake of mixed tenures for top teams Renault and McLaren.

According to IMG Motorsport’s head of clients Martin Anayi, Kovalainen is now regarded by formula one team bosses up and down pitlane as among the top best drivers.

“He is a great guy,” Anayi is quoted by Finland’s Turun Sanomat newspaper.

“Heikki’s potential is obvious and he definitely wants to succeed.”

There have been rumblings in the paddock that Kovalainen is disappointed that, despite being consistently the best of F1′s new teams since 2010, Caterham is yet to break into the midfield.

“This is only the team’s third season, so there are still some growing paints,” IMG’s Anayi acknowledged.

“Heikki has a strong desire to compete, and not just with his teammate Vitaly Petrov. The team’s boss Tony Fernandes wants to get in with the middle group.

“This means that the team needs to regularly get into the Q2 stage of qualifying and in the race be aiming for the points,” he insisted.

Ross Brawn should be firing on all cylinders as he returns to the pitwall in Monaco this weekend.

Mercedes’ team principal sat out the recent Spanish grand prix due to illness, but a scarcity of extra information triggered speculation.

One rumour was that he is seriously ill, whilst another was that his absence may in fact be due to his German employer’s high-stakes spat with Bernie Ecclestone.

The latter theory gained traction since Barcelona, with acting team boss Nick Fry taking a much higher than usual profile, including naming Paul di Resta as a possible 2013 successor for Michael Schumacher.

Explaining his absence, Brawn told Bild newspaper: “On the Tuesday before Barcelona I felt unwell so I went to the doctor and then stayed a night in hospital for some tests.

“When I got home, I decided on the advice of doctors to give myself a weekend off, to be sure that I am fit for Monaco,” the Briton said.

Partly because of Brawn’s deputy Fry’s recent comments, and also due to his paltry points tally and his crash with Bruno Senna, rumours about Schumacher’s future have intensified since Spain.

“A lot has been said and written,” acknowledged Brawn, “but we should not forget that we – the team – have let him down in three of the fives races, not delivering the job we should have.

“We must do better,” Brawn, who worked closely with Schumacher during the seven time world champion’s ultra successful Ferrari era, added.

“We saw Michael’s real quality again in the first race, so it’s for that reason that I believe we will see him on the podium this year.”

As for a possible contract extension for the 43-year-old, Brawn insisted: “When the time comes, we will sit down together and talk about the future.

“I’m sure it will become clear very quickly in what direction we will go.”

Red Bull is lamenting the limited role that can be played in 2012 by F1′s aerodynamic genius Adrian Newey.

For the past few years, the energy drink owned team has enjoyed its dominance largely because of the airflow magic wrought by Briton Newey.

But in 2012, with reigning back to back world champion Sebastian Vettel just one of the five different winners so far, Pirelli rubber is king.

“I doubt Williams really know why they were so strong,” team boss Christian Horner, referring to Pastor Maldonado’s shock Barcelona pole and win last weekend, is quoted by Germany’s Auto Motor und Sport.

Horner insisted that, rather than the winner being the team with the best overall package at each race, success this season is about “understanding the characteristics of the tyre and the window in which they work”.

“It’s not that the midfield teams have made a quantum leap aerodynamically from last year to this year,” Horner insisted. “But from a performance point of view, this is what they have done.”

The logical conclusion is that aerodynamic cleverness has taken a back seat.

So will Red Bull knock a million or two off Newey’s huge annual retainer?

Horner laughed. “Adrian is not just an aerodynamicist, and aerodynamics are still important anyway. But now it’s about harmonising everything, and these tyres are simply remarkably complex.

“Two races ago Nico Rosberg dominated, but in Spain he was almost lapped. It is very difficult to predict what’s going to happen next — a nightmare for the bookmakers,” he smiled. “A lottery.”

The situation has split F1 into two camps: those who love it, and those who do not.

“It has become like a GP2 championship,” Maldonado, the junior category’s 2010 champion, is quoted by The National newspaper.

“The drivers can make the difference and the teams can still work on the strategy and the car.”

The bizarre situation has left everyone scratching their heads, like Jenson Button.

He can scarcely believe that what looked a championship car – his 2012 McLaren – was beaten in Spain by Shanghai winner Nico Rosberg, who was almost lapped.

“The Red Bulls did a better job at the weekend than us in terms of points, but still they weren’t quick when you compare them to Williams, Sauber, Lotus and Ferrari,” he told PA Sport.

“Five different teams winning five different races, we really don’t know what’s going on, and I think that’s the same up and down the pitlane.”

Charlie Whiting has defended the decision in Spain to move Lewis Hamilton from pole to the very rear of the grid.

Although McLaren was widely criticised for making a grave error, the stewards’ penalty was at the same time described by the world’s press as “draconian”.

“Quite frankly I did not expect the penalty that we received,” said McLaren team boss Martin Whitmarsh.

Indeed, given that McLaren’s fuel indiscretion occurred only in the decisive Q3, why not simply delete Hamilton’s Q3 laptimes, thereby putting the Briton mid-grid for the race?

“We had no room to move,” Whiting, the FIA’s race director, responded to Germany’s Auto Motor und Sport when told that Hamilton’s penalty seemed too severe.

“If there is a violation, it applies to the whole session, not just part of it,” he insisted. “Qualifying begins with Q1.”

Whiting explained that if Hamilton had only lost his Q3 time, a precedent would have been set tempting teams to risk not being checked for the mandatory 1 litre fuel sample in post-qualifying scrutineering.

Auto Motor und Sport said only one or two fuel samples are actually checked after qualifying at grands prix.

Competitors could, therefore, genuinely “run the risk” of using less fuel than is allowed in Q3, if the penalty for being caught is relatively light, Whiting argued.

He recalled last year’s German grand prix, when Sebastien Buemi was sent to the back of the grid because his fuel sample showed irregularities.

As it was not possible to check if the illegal fuel had also been used in Q1 and Q2, the Toro Rosso driver had to be disqualified from qualifying, Whiting argued.

Even amid the chaos of the 2012 pecking order, the star performer is obvious.

That is the view of former F1 driver Christian Klien, who confirmed to the Austrian news agency APA that one of his current roles is a simulator driver for the sport’s latest winning team, Williams.

“It (2012) is very open,” he said, “but for me Fernando Alonso stands out.”

Equal with Sebastian Vettel, Spaniard Alonso is at the top of the drivers’ world championship, a full eight points clear of Lewis Hamilton.

The Spaniard’s car has been the struggling Ferrari F2012, but he has never finished a race this season lower than ninth (China).

He has therefore scored points at every opportunity, even finishing first and second in Malaysia and Spain respectively.

“Alonso has an inferior car,” Klien explained, “but he uses every single little opportunity.

“He is the most complete driver who gets the most out of the package he has.”

Triple world champion Sir Jackie Stewart agrees that, among arguably the most competitive grid of drivers since the late 80s, Alonso is the standout performer.

“Right now we have the best generation of drivers we’ve had for a while,” the famous Scot told the Spanish sports daily AS.

“Everyone talks about Vettel, who is a great driver, and also Hamilton of course, but there is also Button, Schumacher, Kimi — all champions.

“There are others like Webber who also have the quality to win, young drivers coming up, many of them are very good, but also it is true that Alonso is fantastic.”

Asked why the Spaniard has not added a title to his tally since 2006, Stewart said: “The explanation is easy — he hasn’t had the luck to get the best car.

“Now he has one that isn’t good, but it’s in those circumstances that you see even more the quality that he has,” said Stewart.

Given Alonso’s push to the top of the championship with a sub-standard car, therefore, all the talk about Ferrari writing off the 2012 championship has been silenced for now.

“We have to keep developing the car,” Stefano Domenicali, Ferrari’s team boss, said after Barcelona, where significant upgrades were brought to the F2012 package.

“We are not yet fast enough to consistently fight for the podium, but that is the only option if we want to be in contention for the title,” 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.”

Narain Karthikeyan has played down reports he could lose his seat at HRT because of a lack of sponsorship.

An Indian newspaper this week said the 35-year-old is a million euros short of guaranteeing his place at the struggling Spanish team through November’s Brazil finale.

“Right now, everything is as it should be,” he is quoted by France’s autohebdo.fr.

“Early in the season, (team boss) Luis (Perez Sala) said that if I was not close enough to my teammate, there is a chance I will not finish the season.

“That was put into my contract, but for now I respect all the conditions. There is no reason that I will not be driving (the rest of) this season,” added Karthikeyan.

He admits, however, to some frustration about HRT’s continuing rear-of-the-field position.

“To be honest I wasn’t expecting the start of 2012 to be on the same lines as last year,” the Indian driver told the Hindustan Times newspaper.

“Yes I expected teething problems but not to this extent.”

He also admits he expected the team to test at Mugello last week.

“Personally speaking, I would’ve preferred some seat time at Mugello since I didn’t get any pre-season testing compared to my teammate who did the Jerez test with the old car,” said Karthikeyan.

“I was originally told that we would do the Mugello test but we decided to focus on putting the car together instead.”

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.

Rubens Barrichello has alleged that Ferrari made a threat that might have ended his motor racing career during the infamous 2002 Austrian grand prix.

Ten years ago, the Brazilian led the race at the A1-Ring but eventually, at the very last corner, succumbed to team orders that allowed number one teammate Michael Schumacher to pass him.

Subsequent video footage has depicted then Ferrari team boss Jean Todt asking Barrichello on the radio to simply “let Michael pass for the championship, please”.

But Barrichello, having left F1 at the end of 2011 for a seat in Indycar, says it was not quite as simple as that.

“It was eight laps of war,” he is quoted by Brazil’s Globo.

“It’s very rare that I lose my temper, but I was screaming on the radio. I kept going right to the end, saying I would not let him pass.

“That’s when they said something about something much broader. It was not about the contract.

“I cannot tell you what they said, but it was a form of threat that made me think about re-thinking my life, because the great joy for me was driving,” said the 39-year-old.

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.”

The boss of Abu Dhabi’s F1 circuit has criticised plans to run the young driver test at Silverstone later this year.

Originally, the young driver test was scheduled to take place as usual this year at Yas Marina, the week after the Abu Dhabi grand prix.

But, due to the calendar congestion at the end of this season, the majority of teams have decided instead to go to Silverstone in July, with only the two Red Bull-owned teams sticking with the Abu Dhabi plan.

Lotus team boss Eric Boullier, however, is quoted by The National newspaper as saying the Silverstone plan is “nonsense”.

Yas Marina chief Richard Cregan agrees: “If you’re a good young driver in the middle of a season, then it’s not ideal to be testing a formula one car midway through the year.

“These guys should be focusing on whatever series it is they are racing, which is why the F1 testing in Abu Dhabi worked so well in the past because it was effectively the end of their season.”

He also warned that the earlier timing of the Silverstone test means teams could spend more time trying to develop their cars than on seriously evaluating the next generation of drivers.

“It is first and foremost a young drivers test and it must remain that,” Cregan insisted.

“It is a chance for young drivers to get maybe a first chance to drive an F1 car and it is chance for teams to run their eye over a driver and evaluate his performance.

“Developing the car and parts should be secondary,” he said.

Abu Dhabi could, however, be back on if Silverstone’s weather forecast looks poor, even though as soon as a car has left the pitlane in July, that team will no longer be allowed to change its plans.

Even though Lotus’ Boullier thinks the Silverstone decision was wrong, he has vowed to stick with the majority.

“But actually I would like it to rain, so we will go back to the original schedule,” said the Frenchman.

Cregan said Abu Dhabi’s door remains open.

“We’ll still be working to the same standards,” he said. “So in that sense nothing changes.”

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.”
