As the roulette wheel spins in 2012, Nico Hulkenberg has admitted he finds himself without a chip on the board.

McLaren, Ferrari, Mercedes, Red Bull and Williams have already won so far this season, whilst Lotus and Sauber have shown genuinely winning pace.

The three backmarkers aside, that leaves just Force India and Toro Rosso as perhaps the only teams without genuine chances of victory so far this year.

“According to our measurements, Williams and Sauber were the fastest cars in Barcelona. They must now be counted among the top teams,” said Force India driver Hulkenberg.

It’s a disappointing situation for the Silverstone based team, a distant eighth in the championship.

“We have definitely improved, especially in traction, but in the fast corners Sauber and Williams are better than us,” Hulkenberg acknowledged to Auto Motor und Sport.

The German admitted Force India has a few tenths to find.

“We have no choice but to develop, because we are behind,” said Hulkenberg. “It’s important to find a good balance between improving the car and understanding it.”

Force India’s 2012 goal, fifth in the constructors’, seems a long way away.

That place is currently occupied by Shanghai winner Mercedes, who are flanked by Malaysia and Spain winners respectively, Ferrari and Williams.

“It is still possible,” Hulkenberg insisted, “although difficult, because the others are still going to be getting points.”

Paul di Resta has hinted he would leap at the chance to replace Michael Schumacher at Mercedes.

The German marque’s Brackley based chief executive Nick Fry this week earmarked impressive Force India driver di Resta, earlier a Mercedes protege, as an ideal successor should Schumacher not stay beyond his 2012 contract.

Asked about Fry’s comments and the media speculation on Wednesday, di Resta said in Monaco: “It’s always nice to have the press interest and people looking out for you, but I need to stay focused on doing the best job I possibly can.”

He told Sky Sports News: “It’s no secret that I want to be a race winner and world champion — and to do that, I need to be in a great car.”

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.

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.”

Flavio Briatore could be readying to burst back into formula one.

Germany’s Auto Motor und Sport said the ousted and formerly banned Italian is busily writing regulations for a ‘GP1′ championship.

They could be adopted should the FIA not sign up to the 2013 Concorde Agreement, according to the report.

Apparently, the political rumblings in F1 at present are not limited to the sport’s planned floatation, or Bernie Ecclestone’s spat with Mercedes.

Cost-control is also a buzzword. As reported recently, the vast majority of F1′s teams want the FIA to enshrine cost-cutting in the actual sporting regulations, even to the point of pushing for a once highly-controversial budget cap.

F1 chief executive Ecclestone, however, is not famously close with the FIA’s new president Jean Todt, and according to Auto Motor und Sport he is not convinced that the Paris federation needs to write and control the rules.

Enter Briatore. The German report said Ferrari will be a fan of the former Renault chief’s rumoured regulations, as they steer away from the premium on aerodynamics.

More than half of Michael Schumacher’s German compatriots think the seven time world champion will return to retirement at the end of this year.

After three years of retirement, the 43-year-old returned to F1 in 2010 on a three-year Mercedes contract, which runs out in 2012.

SID news agency commissioned the German market research company Promit to carry out a survey as to whether respondents think Schumacher will quit at the end of this year.

55.4 per cent answered yes, while only 26.2 per cent said they think Schumacher should sign on for at least another season.

The winner of a record 91 grands prix has failed to see the chequered flag in three of the five races so far this year, finishing just tenth in both Malaysia and Bahrain.

In contrast, teammate Nico Rosberg’s three top-seven finishes in 2012 included pole and victory in China, netting him 41 points compared with Schumacher’s 2 overall.

“I don’t think we can write him (Schumacher) off yet,” insisted Telegraph correspondent Tom Cary this week.

“His pace hasn’t been bad and he started the season very well. (He) was unlucky in quite a few races, his wheel fell off when he was running second in China and could have had a big haul of points.

“He is making mistakes in wheel-to-wheel racing though. But if he gets a few decent finishes or even wins a race then we could see him continue (in 2013),” added Cary.

Sebastian Vettel has defended his former mentor Michael Schumacher.

The seven time world champion has been roundly criticised since last Sunday’s Spanish grand prix, after crashing into Williams’ Bruno Senna at the end of the Barcelona straight.

He called the Brazilian driver an “idiot” on the radio and later defended the outburst, but the FIA did not agree, imposing a five-place qualifying penalty for Monte Carlo for causing a collision.

“For us, that manoeuvre of Michael’s cost us a lot,” Red Bull team principal Christian Horner said on Austrian Servus TV.

He said the debris from the crash not only damaged Vettel’s front wing, but led to the reigning world champion having to serve a drive-through penalty due to activating his DRS wing in the yellow-flag zone.

German Vettel, however, defended Schumacher.

“In those situations we don’t have much time of course,” he said, “and you can get very great speed differences (between the cars) on the straights.

“I think it should be classified simply in the category of racing accidents. Unfortunately it happens,” said the reigning world champion.

“Of course you can always say what is what afterwards,” added Vettel, “just as you can say that it always takes two to tango.”

Mercedes’ Norbert Haug was less eager to comment, although he did tell Germany’s Sport1 that the team “accepts the verdict of the race stewards”.

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.”

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.

Bernie Ecclestone claims he is close to reaching an agreement with Mercedes over the future of the German marque’s involvement in formula one.

The parties have been at loggerheads over the F1 chief executive’s refusal to offer to Mercedes the same Concorde Agreement deal reached with other top teams Ferrari, McLaren and Red Bull.

In response, it has been suggested not only that the situation threatened the sport’s floatation plans, but that Mercedes could sensationally quit F1 at the end of this year.

“We are now 80 per cent there,” Ecclestone told the German newspaper Bild am Sonntag in Barcelona.

“The other 20 per cent, we will get there soon,” he added.

“We have spoken with several Mercedes managers. I am sure we will see more of Mercedes in formula one.”

Bild said the deal being discussed between Ecclestone and the Stuttgart based carmaker will see Mercedes in F1 at least through 2020.

Norbert Haug, however, sounded surprised.

“I have to apologise, but we don’t want to give any information at the moment about the state of the negotiations,” Mercedes’ motor racing vice-president insisted.

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.

Lewis Hamilton on Friday was told he was lucky to escape penalty in Bahrain.

Nico Rosberg’s defensive driving got the lion’s share of the media attention three weeks ago, but in fact it was Hamilton’s pass on the Mercedes that was a more contentious topic during Friday’s drivers’ briefing in Barcelona.

Germany’s Auto Motor und Sport reported that the topic was discussed between the drivers and the FIA’s Charlie Whiting for no less than fifty minutes.

“In the end, it was resolved that Rosberg did nothing wrong. Lewis Hamilton was (unofficially) reprimanded.

“Charlie Whiting said the McLaren driver was lucky not to have been punished.”

The report said Whiting warned the drivers that similar cases, in which passes are made with four wheels off the circuit, will be penalised.

Volkswagen, the German carmaking giant, has played down suggestions it could launch a formula one project some time soon.

“There are always rumours about Volkswagen and formula one,” said Jost Capito, who has taken over from Kris Nissen as the head of the Wolfsburg-based company’s motor racing boss.

However, he is quoted by Germany’s Sport1 as insisting that VW is only concentrating on its world rally programme.

“The WRC programme is approved from 2013 to 2015,” Capito insisted. “There is no room to think about anything else.

“It (F1) is not on our radar,” he is also quoted as saying by France’s L’Equipe. “Our hands are full already.”

In the wake of BMW, Honda and Toyota’s departures, the only mass production carmakers in F1 are Renault – as an engine supplier – and Mercedes.

Ferrari, McLaren, Lotus and Caterham produce niche sports cars.

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.”

A tension has crept into F1 drivers’ relationships, as they look ahead to a fiery meeting at the Barcelona circuit on Friday.

Fernando Alonso had given the first hints about the tension when he hit out at Nico Rosberg’s aggressive tactics in Bahrain three weeks ago.

And earlier this week, the Spaniard insisted there is not enough “respect” between the drivers when they are jostling for position at grands prix.

“Fernando made it pretty clear,” world champion Sebastian Vettel told reporters on Thursday. “He said ‘you have to leave the space — all the time you have to leave the space!’”

Rosberg said he is happy if discussions about his driving take place this weekend, but also in the firing line is Lewis Hamilton, who passed the Mercedes driver on the asphalt run-off in Bahrain.

“I was surprised Lewis was allowed to keep his position,” said Mark Webber.

“I’m sure we’ll talk about it in the drivers’ briefing.”

McLaren’s Hamilton insisted he did nothing wrong, but he added: “I’m not really bothered. It’s good to have clarity.

“Mark is probably one of the most – if not the most – outspoken individuals here (in F1), so that is the least I expect from him.”

Also among the most aggressive – and regularly criticised – drivers is Michael Schumacher, and he insisted that the FIA is fully able to make judgements about incidents.

“If it’s not within the rules the FIA would have taken action,” said the seven time world champion, referring to the incidents in Bahrain. “They didn’t and I didn’t see anything wrong either.”
