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.”

Even ahead of F1′s Singapore floatation, the sport has some new owners.

Reuters, the specialist financial market news agency, said US-based asset managers Waddell and Reed, Blackrock and Norway’s Norges Bank have bought a $1.6 billion stake from existing owners CVC.

The report cited a source “with direct knowledge of the matter”. The companies did not immediately comment.

It drops CVC’s stake from 63.4 per cent to about 40pc, the source said.

We reported on Monday that the Singapore stock exchange approved F1′s plan to raise as much as $3 billion in an initial public offering.

Other reports said pre-marketing for the listing, likely to go ahead at the end of June, will begin immediately.

“It is not our practice to publicly comment on our dealings with listing aspirants,” said a Singapore bourse spokesman.

Some insiders have expressed concern.

“Look at the muted first-day response to Facebook’s IPO,” an unnamed banker told the Singapore broadsheet Straits Times. “The F1 listing is not nearly as attractive and long-awaited as that.”

Felipe Massa has played down reports he is at risk of losing his Ferrari seat soon, insisting he feels fully supported by Ferrari.

The Brazilian has struggled at the wheel of Ferrari’s difficult 2012 car so far, scoring just 2 points compared with his teammate and joint championship leader Fernando Alonso’s 61.

It has triggered speculation the Maranello based team might replace him, also because Ferrari said after Barcelona it is “expecting” Massa to improve “right away”.

Whilst working at Maranello in the driver simulator on Friday, however, Massa insisted he has not been far away from Alonso at recent races.

“I think we must also take into account that, at the moment, Fernando’s driving is amazing: he is on super form, maybe even perfect,” he is quoted as saying in a Ferrari statement.

Asked if he feels the famous Italian team’s support, he added: “Absolutely, yes, I feel the whole team stands by me.

“Obviously, they are not happy with the results and neither am I: we all want to get out of this (situation) and return to normal.

“It’s possible and for sure it’s what I want and I know that with the team’s help we will manage it,” said Massa.

Vitaly Petrov thinks it is possible Felipe Massa will lose his Ferrari seat long before the 2012 season is over.

But Caterham’s Russian driver, who moved from Renault (now Lotus) at the end of last season, does not believe reports that Ferrari could sack the struggling Brazilian imminently, such as after next weekend’s Monaco grand prix.

“I don’t think they’ll fire Massa just now. At least not until August,” Petrov is quoted by the state owned Moscow news agency Ria Novosti.

There are six races until August’s month-long calendar ‘summer’ break.

So while Petrov thinks Massa’s career is genuinely in danger, he does not agree that Ferrari is ramping up the pressure on the 30-year-old.

“I wouldn’t say that Ferrari are criticising him that strongly,” he said. “They’re not saying he has one more chance or anything like that.”

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.

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.”

Paul di Resta has played down media speculation linking him with a high-profile switch to Ferrari.

The reports suggested the famous Italian marque has been impressed with the Scot’s one and a half seasons with Force India and sees him as a potential replacement for the struggling Felipe Massa.

“I have not heard anything about it,” the 26-year-old, who is managed by Anthony Hamilton, said in Barcelona.

“I am just concentrating on the job I have to do for Force India. That is my only focus,” he is quoted by the Scottish Sun newspaper.

However, di Resta is widely regarded as having outshone his highly-rated teammate Nico Hulkenberg so far in 2012.

But he denies he is the number one driver.

“(There is) equal opportunity and everybody seizing his chances,” di Resta told F1′s official website.

As for his dominant position over Hulkenberg, he insisted: “That would be for Nico to answer.”

Hulkenberg said on Thursday: “The first four races have been quite tough but I’m looking forward — I’m bedding in well with the team.”

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.”

Montreal has been warned to spend around $15 million on the Circuit Gilles Villeneuve or risk losing the Canadian grand prix.

La Presse reports that Bernie Ecclestone has said only a major redevelopment of the circuit will lead to talks about a new contract beyond 2014.

The report said that, in light of the F1 chief executive’s warning, Montreal mayor Gerald Tremblay has appealed to higher levels of government for the necessary money.

“Negotiations are underway between the three levels of government and the bodies of formula one”, the report said.

Race promoter Francois Dumontier told RDS: “It’s premature to talk about this.

“There are still two years to go on the current contract. We have started talking, but that it’s out now I find excessive. Honestly, I don’t know where it’s come from.”

He added: “Given that the permanent installations of the circuit, including the control tower and the garages, are nearly 25 years old, it is likely that their repair is an important element in the negotiations for an extension to the current agreement.

“But it seems to me to be premature to talk specific sums.”

Magny Cours is still in the race to host France’s return to formula one.

But according to RMC, the race’s former host – having run the French grand prix between 1991 and 2008 – has been handed a much higher price-tag than Paul Ricard.

Just before Nicolas Sarkozy lost the recent presidential election, the basis of an agreement to annually alternate a French GP with Belgium’s Spa Francorchamps was agreed.

The 2013 host would be Paul Ricard, the Bernie Ecclestone-owned circuit, and the race fee EUR 22 million.

Politics, it seems, have intervened.

Francois Hollande, France’s new president, is not a supporter of the grand prix, and vowed to re-evaluate the sport’s return to the country.

RMC reports that officials at Magny Cours have used the opportunity to “repeatedly” contact F1 chief executive Ecclestone in recent days.

The Nievre region is politically aligned with the new administration, but Ecclestone is reportedly “asking EUR 10 million more” for a race at Magny Cours.

Politics, however, could also be on Paul Ricard’s side, with Citroen’s former world rally boss Olivier Quesnel reportedly lined up to lead the F1 project.

Quesnel is reportedly close to FIA president Jean Todt, and the pair apparently met earlier this week.

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.

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.

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.

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.

Mark Webber has denied signing with the Ferrari team for 2013.

Spanish media reports, indicating that a letter of intent may already have been written, said Fernando Alonso favours Australian Webber to replace the struggling Felipe Massa.

The reports also said Webber, 35 and with an expiring Red Bull contract, could be signed for a single season ahead of Sergio Perez joining in 2014.

“Sergio was flavour of the month last week for the Ferrari drive; now it’s me,” Webber said at the Mugello test on Tuesday.

“I’m focusing 100 per cent on this season and doing the best job for myself and Red Bull Racing. I’m not putting any energy into anything else.”

Italian-language reporters also quote Webber as saying: “There’s a whole season ahead of us before we need to think about the future.

“One day the talk is about Jenson (Button joining Ferrari), then it’s Sergio, now it’s me. I haven’t signed anything.”

“My focus is on this team (Red Bull); we’ve had a good start to the season, we’re only four races down and the road is very, very, very long before we start talking about the future.”

As for the closely-contested 2012 championship, Webber added: “The grid is very close together.

“Sebastian (Vettel) had a weekend without problems in Bahrain and won but he didn’t dominate, and that’s the same for everyone.

“No one will be dominant in the first half of the season, so to be third at the start of the European season is not bad,” he said.
