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.

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.”

It is possible formula one teams will be limited to a budget cap in 2013, according to Germany’s Auto Motor und Sport.

The budget cap idea saw the sport almost implode amid the bitter political war of 2009, when proposed by controversial former FIA president Max Mosley.

But it is back on the agenda in 2012, and according to new rules – where a majority of teams can now push through a change – it could be imposed next season.

“Ten of the 12 teams are in favour,” Auto Motor und Sport said, referring to the push to have cost-cutting moved from the FOTA gentleman’s agreement to the actual sporting regulations.

It means that the two dissenting teams, the Red Bull-owned Red Bull Racing and Toro Rosso, will have no say.

“The cost to be competitive in formula one at present is too high,” the boss of the energy drink company’s premier team, Christian Horner, said recently. “I don’t think anybody will dispute that.

“The debate is how we achieve it.”

Not only that, the German report said nine teams are in favour of Mosley’s old budget cap idea, with annual expenditure limited initially to EUR 170 million and then diminishing to 100 million over a few seasons.

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.

The oddest element of the 2012 season so far is that the unlikeliest of candidates could now be genuine title contenders.

Before the Spanish grand prix weekend, Pastor Maldonado was a commonly derided ‘pay driver’ with 500-1 odds of winning in Barcelona, and just a single point to his name in 2011.

Now, he is F1′s newest pole-getter and race victor, and genuinely regarded as a potential contender for the world championship.

And Dr Helmut Marko, the reigning world champion Red Bull’s motor racing manager, said: “If the Williams really has traction that good, then Maldonado will run rings around everyone in Monte Carlo,” he is quoted by Auto Motor und Sport.

Maldonado travelled straight from Spain to Caracus, where he was being quizzed by the local media as to his chances of a back-to-back victory repeat in Monaco next weekend.

“I think it’s going to be a great opportunity for us to be strong again,” he said.

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.

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.

Despite not topping a Friday timesheet in Barcelona, one specialist publication sees Lotus as the favourite for Spanish grand prix victory.

Germany’s Auto Motor und Sport said the ‘long run’ pace of the black and gold E20 was studied carefully after Barcelona practice.

“Kimi Raikkonen made a great impression on the critical soft tyres,” the report read.

“First, it (the field) is incredibly close. Second, Lotus could win its first grand prix here.”

If true, the former Renault team would become the fifth different winning constructor in the opening five races of the extraordinary 2012 season.

“Our biggest opponent for Sunday is not Red Bull,” an unnamed McLaren engineer is quoted as saying. “It’s Lotus.”

And another surprise pacesetter is Sauber. “Over 15 laps we were better than Red Bull,” team manager Beat Zehnder enthused.

“If everything goes right, we can be on the podium,” he is quoted by the Swiss newspaper Blick.

Agreed McLaren’s Jenson Button: “The Lotus, Sauber and Williams look very strong.”

But in reality, in F1′s new guise of 2012, no one knows what is going to happen on Saturday and Sunday.

“Lord knows what will happen here tomorrow,” wrote The Times’ Kevin Eason. “Well, perhaps He is the only one who does know what is going on — F1 hasn’t a clue.”

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.

McLaren tested a higher front nose at the Mugello test last week.

Backmarker Marussia aside, the famous British team is the only team in 2012 to have resisted the temptation of running a high ‘step’ nose, in the wake of new safety regulations.

McLaren was the early frontrunner this season with its MP4-27 car, but Jenson Button and Lewis Hamilton struggled notably last time out in Bahrain.

Germany’s Auto Motor und Sport said the team quietly tested the significant nose development on the final day of Mugello testing last Thursday, with test driver Oliver Turvey at the wheel.

The report also speculated that McLaren experimented with an adjustable brake duct system at Mugello, which might be used to regulate tyre temperature for the finicky 2012 Pirellis.

The system would have to be adjusted by the mechanics during a pitstop.

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.

Ferrari might be gearing up to incorporate a ‘double-DRS’ setup aboard its improving F2012 car.

If true, the famous Italian team would be the first team to successfully emulate the controversial Mercedes system, which has been declared fully legal by the governing FIA.

Germany’s Auto Motor und Sport said a new rear wing was among the very last upgrades to be trialled by Fernando Alonso as the Mugello test concluded late on Thursday.

“The wing has only minor changes. You have to look closely,” read the report.

The magazine reported rumours that the wing might eventually accommodate the so-called ‘double-DRS’ or 2012-style F-duct, which would work in conjunction with a new and so far unseen front wing.

“That (wing) will debut along with a new diffuser and nose in Barcelona,” added Auto Motor und Sport.

There were happy faces in the Ferrari garage on Thursday, as – despite a minor off by Alonso – the upgrades appeared to work well.

“Barcelona will be a key moment in the season, but not a decisive one,” the Spanish driver insisted.

“It’s not a case that we will suddenly find ourselves back on pole position, because there is no magic button.”

Echoing the earlier words of Mark Webber, Alonso said the “fastest car” at Mugello this week was the Lotus.

Red Bull’s Dr Helmut Marko agrees: “It looks like Lotus are the quickest.”

Veteran Swiss correspondent Roger Benoit wrote in Blick newspaper: “Lotus, with Kimi Raikkonen in super shape, is the championship dark horse.”

An obvious tension was evident at Mugello when Pirelli’s Paul Hembery was asked about Michael Schumacher.

The seven time world champion had slammed F1′s official supplier after Bahrain, arguing that the 2012 tyres degrade so quickly it makes driving a grand prix car as slow as a safety car.

“We haven’t spoken,” Briton Hembery is quoted by Germany’s Auto Motor und Sport. “I’ve just read something on the net about the tyres from his teammate Nico Rosberg which is very different.”

Asked if Schumacher’s criticism was irritating, he answered: “We built the tyres the way we were asked to.

“The FIA, Bernie Ecclestone, even the teams wanted it this way. The spokesman for the teams at the time was Ross Brawn, Schumacher’s team boss.

“There have been four different winners in the four races so far, which alone shows that we must have done something right,” Hembery insisted. “As a fan I would be thrilled.”

Asked if he can at least understand Schumacher’s frustration, he continued: “The four winners this year have not won by chance.

“They were absolutely the best drivers in those races and all of them were faster than their teammates.

“I can understand that Michael was frustrated at the last race. Among the four winners so far were two Germans, and then you had Kimi (Raikkonen), who in the fourth race of his comeback is on the podium.

“Racers are winners; they’re not happy unless they’re winning.”

Hembery denied that tyres have, in 2012, become more important than the cars or drivers.

“That’s a misconception,” he insisted. “The driver has a huge impact.

“Anyway I’m convinced that at Silverstone at the latest the teams will have the problem under control. Just as they did last year.”

Finally, he insisted that Pirelli is not going to make any knee-jerk reactions.

“If there are 23 drivers satisfied and only one dissatisfied, then I don’t think we need to change something,” Hembery is quoted by Bild newspaper.

Ferrari’s Fernando Alonso, however, acknowledged a slight frustration.

“For the top teams it’s a bit frustrating,” he told La Stampa newspaper, “when it’s difficult to exploit all your potential.

“It’s like Real Madrid, Barcelona and AC Milan suddenly playing with the budget of Cesena.”

Sauber was the team with the biggest update package as F1′s ultra-rare in-season test began on Tuesday.

Kamui Kobayashi was in charge of the revised C31, which including a new exhaust and front wing represented “the biggest update package” of all the teams at Mugello, according to Germany’s Auto Motor und Sport.

McLaren, in contrast, have taken “no great updates” to Tuscany, which explains why Lewis Hamilton and Jenson Button have left the task up to the British team’s test drivers.

It was a similar story in the Mercedes camp.

Williams’ Valtteri Bottas, however, was in charge of testing a new McLaren-like exhaust for the FW34, while Ferrari also has a new exhaust for the F2012.

On Thursday, as the three-day test wraps up, the famous Italian team will debut other developments, including a new engine cover and sidepods.

A new front wing, nose and floor will only be ready for Barcelona.

There were no radical modifications on display by Red Bull, who instead want to use the Mugello test to work on car setup.

“We still need to learn how to get the most from what we have,” confirmed Bahrain winner Sebastian Vettel.

For that purpose, the Ferrari-owned Mugello circuit might not actually be the best venue.

“It’s great for driving,” said Mercedes’ Nico Rosberg, “but for the engineers Barcelona would be a bit better because there are all types of corners.

“At Mugello they are mainly fast, and virtually none at low speed.”
