The key backer of the scheduled 2012 US grand prix insists he remains committed to the Circuit of the Americas project.

Construction in Austin, Texas, has continued amid raging local media speculation, as lawsuits are pending and questions are constantly asked about the viability of the project commenced by the now offside promoter Tavo Hellmund.

With 84-year-old billionaire Red McCombs now reportedly in the driving seat, he insisted it is “without question” he will continue to push the project forwards.

“Never has been any question,” McCombs is quoted by mysanantonio.com, after the authoritative Austin American Statesman newspaper had suggested he was on the verge of pulling out.

“I’m there for the full ticket,” McCombs insisted, although he admitted the row with Hellmund is proving a speed-bump.

“I will say we do expect to have some resolution to those issues in a timely fashion, but in dealing with the courts, I don’t know what a timely fashion is.”

He told reporters the circuit is now 60 per cent complete ahead of the inaugural November 18 race date.

Angry students could threaten next month’s Canadian grand prix.

Protests in Montreal, regarding planned university tuition fee increases, have been turning increasingly ugly and even violent, involving the throwing of glass bottles and hundreds of arrests.

According to the French language La Presse newspaper, at least one student association has specifically threatened to disrupt the F1 race, scheduled for 10 June on the nearby Il Notre Dame.

“I cannot deny that we are following this out of the corner of our eye and will continue to follow it in the coming days,” admitted race promoter Francois Dumontier.

The report said students’ chants at recent demonstrations included references to the grand prix.

At a recent meeting, one association of students approved a resolution to adopt “a weekend of disruption” aimed at “the cancellation” of the race, which represents “sexist, non-environmental and elitist” values.

“It is not clear that we will be targeted,” Dumontier insisted, “but we are an international event and are ready with a safety plan ranging from dealing with simple mischief to a wider disruption.

“The grand prix is often targeted because we are a major event. We are not worried but we have our eyes open and will work with the public authorities,” he added.

Money could be at the heart of the delay in Lewis Hamilton’s re-signing with the McLaren team.

Until now, the British team has indicated it wants the 2008 world champion to stay on board, while 27-year-old Hamilton insists he has no plans to leave and will turn his attention to the 2013 contract soon.

But according to Blick newspaper, McLaren is pushing to cut Hamilton’s existing contract retainer “in half” to “about EUR 10 million”.

The Swiss report said the driver is unimpressed with the negotiations so far, but at least Hamilton’s mood has improved tenfold compared with his calamitous 2011.

It is a full year since Hamilton raged about his “frickin ridiculous” track rivals in the 2011 Monaco grand prix, when he also half-seriously suggested that the stewards were targeting him “because I’m black”.

He is back on top form this season, but still yet to win a race, arguably mainly due to McLaren’s numerous team mistakes.

Reports have suggested boss Martin Whitmarsh, who insists Hamilton “deserves” to win this weekend in Monaco, is worried the mistakes might drive the highly rated racer away.

On Wednesday, however, Hamilton denied he is frustrated.

“I’m not, no. This is the way racing goes sometimes,” he insisted.

“I could easily get frustrated because I could have a healthy lead in the championship — but that’s not the case.

“I don’t want to speak too early but something has definitely changed. Whatever I’m doing is working,” he told British reporters.

“In life, things just seem a lot better and that’s enabling me to get on with my job without having any baggage.”

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.

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.

A favourite for victory this weekend, Pastor Maldonado is reportedly lucky to be gearing up to race in the Principality at all.

Bild newspaper recalls that the Venezuelan, who defied his ‘pay driver’ critics by winning for Williams in Spain two weeks ago, was actually banned after an horror incident on the streets of Monte Carlo seven years ago.

Racing in the Renault World Series in 2005, the then 25-year-old ignored yellow flags before striking and severely injuring a marshal.

Organisers of the Monaco grand prix reacted by banning Maldonado from the street circuit for life.

Germany’s Bild revealed that Maldonado’s wealthy father intervened, promising to pay for the marshal’s recovery and rehabilitation from a broken back.

That intervention saved Maldonado’s future formula one career, as no team would hire a regular driver that cannot participate in the sport’s most famous race.

Maldonado is therefore a favourite for victory this weekend, with his Williams now acknowledged as arguably the best in the entire field when it comes to slow-speed traction.

And in his four seasons of GP2 between 2007 and 2010, Maldonado finished on the podium each time, winning and achieving pole position twice. In 2006, he won in Formula Renault.

Last year, in qualifying for his first Monaco grand prix, he qualified his then struggling Williams in eighth place, comfortably ahead of Rubens Barrichello.

“He is very good at Monaco,” agreed Barrichello.

In the 2011 race, Maldonado was fighting for fifth when he crashed with Lewis Hamilton.

“If the last sector in Barcelona is the marker, then the Williams will be unbeatable in Monte Carlo,” Germany’s Auto Motor und Sport quotes Dr Helmut Marko as saying.

The breakthrough success in Barcelona has piqued the interest of Maldonado’s native Venezuela, having not had an F1 points scorer since the ignominious Johnny Cecotto in 1983.

“My country will be following every second of the next race,” Maldonado is quoted by O Estado de S.Paulo newspaper.

“I love street circuits, this one in particular. My style of driving fits perfectly with Monaco. I am ready to get another great result.”

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.”

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.”

Jaime Alguersuari has told Spanish publications he is “absolute certain” he will be on the 2013 grid.

“This is the best year of my life,” he told Mundo Deportivo, referring to 2012, the year after his young F1 career stalled when he was dropped by backer Red Bull.

“I’m only 22,” said Spaniard Alguersuari, who is now Pirelli’s main test driver and a co-commentator for British radio. “I’m in the prime of my life.

“It is increasingly clear that what happened with Toro Rosso was not a sporting decision. It was an internal decision and I don’t want to go deeper.”

He sounded confident about the future.

“It is 100 per cent that I will return in 2013. After being with Pirelli I will have very important knowledge. I knew that this transitionary step was necessary and I’m very happy,” said Alguersuari.

“If I had gone (to be test driver) with a team, with all due respect, I’d have no options now.

“I am developing a product (Pirelli) that nobody understands but that is vital for formula one — to know the tyres and to understand them. I’m in the right place,” he is quoted by La Vanguardia newspaper.

“I chose to be with Pirelli because I knew it would be the most important (element) in formula one.

“I know where I am and I know where I’ll be next year,” he insisted.

Martin Whitmarsh is sure McLaren’s recent errors will not affect contract negotiations with Lewis Hamilton.

The British team’s latest mistake not only cost Lewis Hamilton pole in Spain, it put the 2008 world champion to the very back of the grid.

Asked if he worries that the now seemingly constant flow of team gaffes will damage McLaren’s efforts to re-sign Hamilton, Whitmarsh insisted: “No, I don’t.

“He has got to build the support of the team, he has got to feel comfortable doing it, he has got to want to drive and he is in good shape,” British newspapers quote the McLaren team principal as saying.

“I look forward to working with him for a long time to come.”

But Whitmarsh admitted that, given Hamilton’s tumultuous 2011 season, he was worried the British driver might have despaired last Saturday when the team’s refuelling mistake cost the 27-year-old pole.

“I was concerned,” he said, “because it is a pretty tough thing to happen to a driver.

“But I have to say he showed some greatness I had not seen before. By the end of our chat he was consoling me.

“The relationship between Lewis and the team is stronger and better and hopefully we will work together for a long time,” added Whitmarsh.

Five races in, F1′s cleverest brains are still yet to decode the mystery of the bizarre and fascinating 2012 season.

As was the case when he utterly dominated last year, Sebastian Vettel is still leading the drivers’ points chase.

But, before last weekend, if he had been told that Williams’ Pastor Maldonado would be the winner of the Spanish grand prix, the German admitted: “Well, I would have put a lot of money on them!

“I think the odds weren’t bad,” he smiled.

Indeed, the major British bookmaker William Hill was taking bets at 500-1 prior to the Barcelona weekend.

A spokesman confirmed that only two bets at 10 pounds or above were placed on Maldonado prior to qualifying.

“I’m sure Williams don’t understand why they just won the race here,” McLaren’s Jenson Button is quoted by the Guardian newspaper.

But the previously-derided ‘pay driver’ Maldonado is not the only potential new winner in 2012, after Jenson Button, Fernando Alonso, Nico Rosberg and Vettel won the opening four grands prix.

A detailed look at F1′s specialist reporting in the past few weeks shows that Lewis Hamilton, Mark Webber, Kimi Raikkonen, Romain Grosjean, Michael Schumacher, Sergio Perez and Kamui Kobayashi are all also widely regarded as genuine victory candidates in 2012.

And given that their teammates have won grands prix this season, even the struggling Felipe Massa and Bruno Senna should be added to that list.

“Dammit, let’s go for (HRT’s) Karthikeyan!” wrote Chris Hockley in the Sun newspaper.

“It’s really quite crazy right now,” Vettel, who despite his young age would count himself among F1′s currently perplexed purists, told Germany’s Auto Motor und Sport.

“What’s happening is difficult for us to explain,” he added.

The situation has split the F1 audience, with the purists shaking their heads, and others marvelling at the unprecedented spectacle.

“The spectacle has taken over the sport,” said the Paris daily Le Figaro.

“Even the teams can’t be sure who will be the hare and who will be the tortoise at any given track,” wrote Hockley.

Alonso, who is the joint championship leader, is in the purists’ camp.

“Of course it is attractive for the spectators that we are going to Monaco not knowing if we will fight for victory or be left out of the points,” he is quoted by El Pais.

“But in a way, after eleven years in formula one and now I’m at Ferrari, I would like to have more stability,” the Spaniard admitted.

Sir Jackie Stewart said: “What’s going on is unbelievable, which I think is the outcome of the new rules, new tyres — I think it’s many factors,” he told the Spanish sports daily AS.

“What’s happening,” said Maldonado’s race engineer Xevi Pujolar, “is that these tyres are allowing teams who do not have the biggest budgets to be eligible for really good results.

“The reason is that the most important thing now is to have a good setup and also some luck with the temperature.”

Pirelli, F1′s tyre maker, has received both criticism and praise for its huge role.

“Pirelli have been both bold and brave,” Sun journalist Hockley said. “It can’t be easy for a manufacturer to make tyres that sometimes wear out faster than you can say Mercedes.”

Marco Tronchetti Provera, the Italian marque’s company chief, is unapologetic.

“What we have provided is what the teams have asked for, and it was not easy,” Italian language reports quote him saying. “Our engineers have done an extraordinary thing.”

Felipe Massa’s formula one career is on the brink of collapse.

Ferrari boss Stefano Domenicali left Barcelona insisting he expects the struggling Brazilian to “fight back starting in Monaco”.

“We absolutely need his points to also fight for the constructors’ title,” he said.

Earlier, the Maranello based team said on Twitter that Ferrari is “disappointed with” the 30-year-old’s performance.

When asked about that comment, a Ferrari spokesman told the Sunday Times: “It was a poor choice of grammar. We are disappointed in the outcome of Felipe but not with Felipe himself.”

But the very latest development is that Ferrari is now making it abundantly clear that Massa needs to up his game immediately.

In a statement posted on its official website, Ferrari said Massa’s teammate Fernando Alonso “has always maintained a very high level”.

As for Massa, his “drop off has made itself felt”, the report stated.

“The Brazilian had picked up 49 points two years ago and 24 the following year, while so far this season he has just 2,” said Ferrari.

“Everyone, he more than anyone, is expecting a change of gear starting right away with the Monaco grand prix”, the statement concluded.

Even Massa’s strongest supporters in Brazil, like the O Globo journalist Celso Itibere, admit the situation is dire.

“He is at risk,” said Itibere, “his decline is progressive, he is failing to react and he runs the real risk of not finishing the season.

“At this time Ferrari has no one to take the job. Everyone they would like to have there – Perez, Kobayashi, Webber – are not available.”

Tuesday’s edition of the Italian sports daily Corriere dello Sport will report that Massa’s ousting is imminent.

And the latest edition of La Gazzetta dello Sport did not even once mention Massa’s name. “It is as though he does not exist,” wrote the Brazilian journalist Livio Oricchio in O Estado de S.Paulo newspaper.

“Yet it is an Italian newspaper, and he is a Ferrari driver.”

When asked if he fears for his F1 career, Massa said in Barcelona last weekend: “No. I live in the present. What will happen will happen.”

Asked if he is afraid another bad performance will seal his fate, Massa insisted: “I’m not afraid of anything, especially criticism. It doesn’t affect me.”

Two days after winning in Spain, Williams is scrambling to put together the equipment it needs to contest next weekend’s Monaco grand prix.

Mere hours after Pastor Maldonado secured the once-great British team’s first victory since 2004, a huge fire broke out in the pits, leaving one team member still in a Barcelona hospital with burns.

“His family are in constant communication and he is in good spirits,” Williams said in a media statement.

The Oxfordshire based team is now making efforts to ensure it can race in Monte Carlo, having lost a lot of equipment in the fire.

Mercifully, however, Bruno Senna’s car appears to have survived, with the Finnish broadcaster MTV3 saying an initial inspection of the chassis showed no devastating damage.

Maldonado’s winning car was in parc ferme at the time of the incident.

“We had a lot of damage and lost a lot of equipment, including IT equipment,” chief operations engineer Mark Gillan said, according to the Daily Mail.

“Over the next couple of days we will be looking at where we are parts-wise.

“We will have everything we need to run operationally at Monaco, but we may be missing a few of the extras because obviously we don’t carry a complete set of spares for everything,” he said.

It is believed more than one rival team has offered to help Williams by loaning the Sir Frank Williams-led outfit any equipment it needs.

A McLaren spokesman confirmed the Woking based team has offered to help.

Germany’s Bild newspaper said Williams’ damage bill runs into the millions.

Team manager Dickie Stanford denied a rumour the fire was caused by a cigarette in the vicinity of Senna’s fuel tank while it was being emptied.

“We don’t know the cause, but we would never allow smoking in the pits,” he insisted.

Williams and F1′s governing FIA are investigating.

F1′s season of confusion looks set to continue, with an uncertain weather forecast only adding to the uncertainty ahead of the Spanish grand prix.

The bizarre 2012 contest stepped into yet another gear on Saturday, with events unfolding to put the previously-derided pay driver Pastor Maldonado on pole, alongside the crisis-ridden Ferrari’s Fernando Alonso.

And the Pirelli tyre predicament, worsened on the challenging Circuit de Catalunya layout and under hot Spanish skies, will continue to confound teams on Sunday, with temperatures set to drop and rain clouds predicted to gather.

“I am telling you now, honestly,” said Red Bull’s Mark Webber. “We don’t have even the slightest idea who will benefit when it gets colder.”

The German magazine Auto Motor und Sport laid out the fascinating if bewildering situation as of Saturday in Spain: “Sebastian Vettel doesn’t know why his car suddenly lost grip in qualifying.

“Jenson Button has no idea why he couldn’t generate any tyre temperature on the 40 degrees track. Williams don’t know why Pastor Maldonado clocked the second fastest lap.

“Mercedes’ engineers had to admit they still don’t understand the Pirelli rubber.”

Acting team principal Bob Bell smiled tortuously: “If we did understand, we’d be on pole. But even Pirelli don’t know all the answers.”

Writing in O Estado de S.Paulo newspaper, Livio Oricchio estimated there are up to 12 candidates for victory.

“A grid of madness!” said former F1 driver Patrick Tambay on France’s RMC Sport. “And it’s not over yet.”

So, is Michael Schumacher – having sat out Q3 in order to save tyres for the race – now even more critical of Pirelli?

“I’ll leave it with what has already been said,” he insisted late on Saturday.
