It is believed static electricity could have sparked Williams’ garage fire two weeks ago in Barcelona.

Even in the Monte Carlo paddock, the huge Spanish blaze was still a hot topic.

The British team and the FIA conducted investigations, but there has been no definite finding about the cause of the fire.

Germany’s Auto Motor und Sport reported suggestions simple static electricity, caused by the specific weather conditions and the fact a container was not grounded at the time, was the culprit.

Williams has scrambled to be ready for Monaco, but the only obvious sign of the fire on Wednesday was one missing mechanic, who is still recovering from burns.

“He’s on the road to recovery,” said co-owner Toto Wolff.

It is believed the mechanic was pumping fuel from one container to another when the fire started.

Wolff confirmed the static electricity theory.

“This is extremely rare. The weather may have played a role, as we had low pressure over Barcelona that day,” he explained.

Auto Motor und Sport said Williams lost mainly computers in the fire, but the crucial data survived. Of the team’s 150 radios, only 40 were intact.

Wolff said Bruno Senna’s chassis survived because of the partitions at the back of the main pit area.

“They are flame retardant,” he confirmed. “This meant the fire did not come beyond the back (area). The walls melted in the heat, but they didn’t burn.”

And financially, the Oxfordshire based team is completely undamaged, due to insurance.

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.”

F1′s next winner could be at the wheel of a black and gold car.

“I think Kimi (Raikkonen) will be the sixth different winner in the sixth race,” said Finnish commentator and former driver Mika Salo, to the MTV3 broadcaster.

Although the results in 2012 have proved impossible to predict so far, many paddock pundits expected Lotus’ E20 to be the car to beat last weekend in Barcelona.

“The big surprise was when Kimi didn’t win,” admitted former Ferrari driver Salo, referring to Pastor Maldonado’s victory for Williams.

Also confident about Lotus’ potential is Raikkonen’s teammate, Romain Grosjean, who finished behind the 2007 world champion last weekend.

“It’s good to be a little disappointed with third and fourth,” he told the French language RMC Sport. “It shows that as a team we are convinced we can win.”

According to the reigning world champion team Red Bull’s drivers, however, there is a downside to this year’s impossible-to-predict F1 landscape.

“Maybe we will see an HRT or a Marussia on pole in Monaco,” world champion Sebastian Vettel said, unenthusiastically and half-seriously.

Mark Webber insists that what has been described as the Pirelli ‘lottery’ might not be a good thing for the sport.

“I don’t know if they (the fans) will get sick of seeing so many different winners,” the Australian told Fox Sports.

“It’s nice to have different winners but also we want rivals.”

Ferrari has played down rumours it is close to immediately ousting Felipe Massa, insisting it is possible the struggling Brazilian will still be in a red car next year.

On Twitter, the famous Italian team said the latest rumours – including a claim that former Virgin driver Jerome d’Ambrosio is a candidate to replace Massa in 2012 – are “funny”.

But it was Ferrari itself who fuelled the speculation, publishing a statement on its website that read like a warning to Massa.

“It was a very carefully-worded statement, wasn’t it?” said Telegraph correspondent Tom Cary.

“The way this crazy season is going, I really would not be massively shocked if they ditched him mid-season.”

The Swiss newspaper Blick said Monaco next weekend could be the 30-year-old’s last chance to up his game.

And the candidates are lining up.

“Ferrari knows that I’m ready. If they need me or they want me, then they will call me,” Adrian Sutil, who accompanied his manager to last weekend’s Spanish grand prix, said.

The Spanish newspaper El Mundo said some paddock pundits believe “the only reason” Massa still has its seat is because the “name Todt” – a reference not only to Massa’s manager Nicolas but to the FIA president – has a “protective arm” around him.

Ferrari spokesman Luca Colajanni told Brazil’s O Estado de S.Paulo newspaper this week: “Felipe has the full confidence of the team, starting with our president.

“We have not decided who will be our driver in 2013 but Felipe is not ruled out,” he insisted.

Indeed, while some believe Ferrari has hung a sword of Damocles above Massa’s head, others think the Maranello based team have been patient since the Paulista’s recovery from his near-fatal head injuries of 2009.

“We have no evidence that makes us think that Felipe has slowed down because of the accident. Zero,” Colajanni said.

F1 doctor Gary Hartstein agreed: “An experience like that (Hungary 2009) changes you, but you can’t say that’s why Felipe has not won again.”

Preparations for the inaugural Russian grand prix in 2014 appear to have hit a roadblock.

We reported last weekend that rumours were circulating in the Barcelona paddock that the Sochi race now appears “doomed”.

The state owned Moscow news agency Ria Novosti now reports that political issues have created “serious delays” in the race’s preparations, according to an adviser with the Russian Automobile Federation.

The official, Igor Yermilin, insisted that the project is not doomed, but he said very few efforts have taken place following the bureaucratic reshuffling of the local Krasnodar region.

He said some officials of the Omega company, responsible for the F1 circuit project, have lost their jobs.

“In the Krasnodar region there has been have been quite serious changes in the leadership,” Yermilin said, “including people from Omega who signed the contract on holding the Russian grand prix”.

The coastal city Sochi is also scheduled to host the 2014 Winter Olympics.

“The main thing at the moment is the Olympics — the grand prix is on the back burner,” said Yermilin.

The drama stepped up a notch even after the chequered flag in Barcelona.

A couple of hours after Williams’ first win since 2004, something exploded in the British team’s garage, triggering a major fire.

Team members and fire crews battled the blaze as paddock regulars scrambled away from the heavy smoke and police arrived on the scene.

The Telegraph’s Tom Cary said on Twitter there are “multiple injuries”.

It is believed Williams, Force India and Caterham staff – some of whom bravely fought the fire – are being treated in the medical centre, some for smoke inhalation.

An emergency helicopter will ferry others to hospital.

“Couple of our guys got injuries, burns and maybe one broken wrist, no news on Williams guys I hope they’re ok,” wrote Caterham’s Heikki Kovalainen on Twitter.

Rumours indicated the fire could have been caused by a KERS explosion, or possibly fuel, as a burned fuel rig was pulled from the gutted garage.

F1′s astonishing season continues to live up to the hype, as a fifth driver and constructor on Sunday won the fifth grand prix of 2012.

Not only is the victory Pastor Maldonado’s first, his walk up the steps at the Circuit de Catalunya was the first taste of the podium in his two-season F1 career.

It’s also the first Venezuelan triumph in the sport’s history, and a hugely popular victory for Williams, the once-great British team headed by Sir Frank Williams, whose 70th birthday was warmly celebrated in the paddock on Saturday.

“Boy did we need that,” said Williams on BBC television.

And asked how he feels on Sky television, he smiled: “Relief.”

“Some said Maldonado was a pay driver and he didn’t deserve his place in formula one but they’ll be eating their words now,” commented former team driver David Coulthard.

“That was a fantastic drive,” added Coulthard, referring to Williams’ first win since Juan Pablo Montoya in 2004.

Williams enthused: “I didn’t see him (Maldonado) make one single mistake.”

“You can’t really fault him,” agreed Williams’ 1996 world champion Damon Hill.

Amazingly, however, away from the champagne, Sebastian Vettel’s sixth place leaves him at the top of the drivers’ championship, and he is now neck-and-neck with Fernando Alonso, who finished second on Sunday in the improving Ferrari.

Lewis Hamilton, who finished dead last on Sunday and finished eighth, is third in the points classification, ahead of Lotus’ Kimi Raikkonen.

Finn Raikkonen finished third on Sunday, and is the favourite to become F1′s sixth different winner of 2012 in Monaco in a fortnight.

“We showed we still have the speed,” the Lotus driver said after the Spanish grand prix. “If we had a few more laps, we could have fought for a victory.”

The penalty might be harsh, but the loss of Lewis Hamilton’s pole in Spain is just the latest calamitous mistake by McLaren.

That was the tone of the paddock’s reaction to the news late on Saturday that a McLaren gaffe saw the FIA send Hamilton from first to last on the Spanish grand prix grid.

The Sun newspaper called it a draconian “24-place grid penalty” imposed by the FIA after an “astonishing cock-up” by McLaren.

Hamilton was told on the radio to pull over after his pole lap due to a “technical problem”.

Sporting director Sam Michael argued ‘force majeure’, but the stewards ruled that it had been entirely McLaren’s fault that not enough fuel was put into Hamilton’s car to ensure a scrutineering fuel sample.

Writing in the Telegraph, Tom Cary said the severity of the disqualification “raised eyebrows”, but agreed that “McLaren’s mistake was horrendous”.

He said it has been “a season of errors” by the famous British team, who are yet to get Hamilton’s signature on a new contract beyond 2012.

“Hamilton must be seething,” read an article in the Daily Mail newspaper, while The Times laid out McLaren’s “catalogue of errors”.

27-year-old Hamilton’s “raw talent is being thwarted by mishap and cock-up,” said journalist Kevin Eason.

“McLaren are lovely people but how the hell do they get themselves in this position?” wrote the Mirror’s Byron Young on Twitter.

Even the non-English language media agreed.

“It was another great mistake by McLaren that could eventually cost Hamilton the championship,” wrote Livio Oricchio in O Estado de S.Paulo.

Italy’s La Stampa called McLaren’s fuel gaffe a case of “harakiri”.

Germany’s Auto Motor und Sport added: “It was error number 13 for McLaren since last year”.

While highly critical of McLaren’s own-goal, however, the feeling in the paddock is that the stewards’ penalty – although accepted by McLaren – was overly harsh.

“Back of the grid? Way, way too harsh”, said the Mirror’s Young on Twitter.

“Draconian penalty in my view,” agreed PA Sport’s Ian Parkes. “Dropping Q3 time would have sufficed.”

Sky commentator Martin Brundle added: “(I) feel they should have deleted that (Q3) laptime only which would have put him sixth”.

And excluding Hamilton from Q3 altogether would have put him 11th. Now, he will be “lucky to score a point”, Auto Motor und Sport predicted.

In the Independent, however, David Tremayne noted: “Welcome to the draconian world of F1.”

David Croft, the lead Sky commentator, said the FIA stewards had acted correctly.

“A good rule should be one that covers all eventualities with a penalty that acts as a deterrent which in this case is what happened.

“Too little fuel can’t be tolerated,” he added. “It seems harsh but had Lewis taken pole by one thousandth of a second, would it be harsh then?”

The Spanish fans – not Hamilton’s biggest supporters dating back to his spats with Fernando Alonso in 2007 – were happy.

Asked on the El Mundo website whether the penalty was fair, 76 per cent answered yes.

Valencia will not be on next year’s F1 calendar, Bernie Ecclestone said on Saturday.

He confirmed that, starting in 2013, an annually alternating deal between the Spanish port city and Barcelona will begin.

Barcelona, the scene of this weekend’s Spanish grand prix, will host the race in 2013, before Valencia returns to the schedule in 2014, the F1 chief executive told Reuters.

Less secure, meanwhile, is France’s touted spot on the 2013 calendar, particularly with the country’s new anti-F1 president Francois Hollande now taking power.

Until recently, the F1 chief executive was saying Paul Ricard was set to join the 2013 calendar, annually alternating a race date with Belgium’s Spa Francorchamps.

As for the state of the deal now, the 81-year-old admitted: “I have no idea. No idea what they (France) are doing.

“It’s a funny arrangement they were making anyway. So I just don’t know.”

Ecclestone is also working on a new deal for the popular Canadian grand prix, having told promoter Francois Dumontier that the Circuit Gilles Villeneuve needs to be upgraded.

“There are two ways of looking at it,” Dumontier, in the paddock of the Circuit de Catalunya, is quoted by La Presse newspaper.

“Either Bernie requires an annual fee windfall, or he will charge a reasonable fee and ask in return for investment in the infrastructure.”

He said the contract on the table is for 10 more years, taking Montreal’s existing deal through 2024.

Ecclestone said on Saturday that he is sure an agreement will be reached, because Canada is one of F1′s most loved destinations.

“I remember saying to Bernie, ‘New York, Austin, I don’t know why you want to go there. Your sure bet is Montreal’. He knows that.

“He’s been in Montreal for 34 years. And in the 22 years of the grands prix in the United States, they’ve had eight different cities.

“He said ‘You’re right’,” added Dumontier.

Another rumour, repeated by The Times’ Kevin Eason on Saturday, is that the planned 2014 Russian grand prix in Sochi “is doomed”.

Top teams McLaren and Red Bull have questioned whether F1 should have tested last week.

Since the sport clamped down hard on private testing for cost reasons some years ago, there remained many in the paddock – notably Ferrari – who argued that at least some in-season testing should still take place.

So, for 2012, it was agreed that Mugello would host a three-day session in between the Bahrain and Spanish grands prix.

Every team except HRT attended.

But there were rumblings that not everyone was happy. McLaren, in fact, did not even send its race drivers Jenson Button and Lewis Hamilton to Tuscany.

Then, on Friday in Spain, the British team’s regular duo was busily testing in official practice, fielding extravagant sensors and experimental components.

“We would have had a very similar programme whether we went to Mugello or not,” said sporting director Sam Michael.

“All the teams are geared up to not have testing, to not having test teams and that means we’re equipped and do our planning to do all of that work on Friday.

“I think the (Mugello) test itself, personally, I think you could do without it,” Michael continued. “I think it’s a lot of energy and expense during the season that we probably don’t need.

“Of course McLaren will gain a lot out of that test but formula one is all relative, so all we really did was spend a load of money.”

Red Bull’s technical boss Adrian Newey agreed.

“I think we learnt the pasta in Italy is still the best in the world and that’s about it really,” he said when asked about the Mugello test.

“I’d agree with what Sam says. To me, yes you go to the test because it’s available. We all spent money but the value of in-season testing has to be questionable.”

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.”

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.

Mark Webber might have signed a pre-contractual agreement with Ferrari, one of Spain’s leading F1 correspondents has revealed.

Raymond Blancafort, writing for El Mundo Deportivo, referred to widespread speculation in the paddock about Sergio Perez’s likely future alongside Fernando Alonso.

“There may be a pre-contract,” he said, “but between Ferrari and Webber.”

Australian Webber was also linked with Ferrari last year, before Red Bull decided to sign him up for another single season.

The 35-year-old was overshadowed by his teammate Sebastian Vettel last year, but he has begun the 2012 season more strongly.

And Webber warned before the 2012 season began that if Red Bull didn’t re-sign him for 2013, “I’d need something (else) competitive (to drive)”.

“Being at the front, is certainly a big, big factor of me staying very hungry and motivated.”

Ferrari may be looking to replace Alonso’s current teammate, the struggling team veteran Felipe Massa, for 2013.

“They (Ferrari) would be able to take advantage of his (Webber’s) experience, the consistency of his results and the fact that he gets along with Alonso.

“Interestingly, Webber is also still involved with Flavio Briatore”, as is Alonso, Blancafort noted.

Olivier Panis is happy with the early progress of French rookie Charles Pic’s 2012 season.

Panis, the 1996 Monaco grand prix winner and veteran of over 150 formula one races, now manages the career of 22-year-old Pic on behalf of the Lagardere group.

“I had the chance to talk with Ron Dennis on the grid,” the former Toyota racer and McLaren test driver Panis told RMC, “as he had come to see him (Pic).

“It shows that nobody is indifferent to what he is doing so far.”

Panis, 45, revealed that Pic is also spending “a lot of time” in McLaren’s driver simulator, thanks to the technical agreement between Marussia and McLaren.

“He is building an image slowly, which is positive. He has earned the respect of the paddock, and now we have to continue,” Panis added.
