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.”

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.

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.”

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.”

Kimi Raikkonen is not ruling out victory in Barcelona this weekend.

If he does succeed on Sunday, the Finn will become the fifth different driver, driving for a fifth different team, to win the fifth grand prix of 2012 — an almost unthinkable scenario for formula one.

Not only that, some believe that – despite McLaren, Ferrari, Mercedes and Red Bull having fielded the winning cars so far in 2012 – Lotus is actually the favourite in Barcelona.

Raikkonen and his teammate Romain Grosjean were both on the podium in Bahrain, and the black and gold E20 set the pace last week at the Mugello test.

“You would say now that the Lotus and the Red Bull are the cars to beat,” said Melbourne winner Jenson Button on Thursday.

Raikkonen, openly disappointed about his second place recently, hopes so.

“If everything goes smoothly then we can be up there,” he told reporters on Thursday.

He agrees that the car was a true pacesetter in Bahrain and Mugello.

“Let’s hope it works just as well if not better here,” Raikkonen, 32, told the Finnish broadcaster MTV3 at the Circuit de Catalunya.

“Then we will at least have the possibility of victory,” he added.

He does not, however, want to talk about the championship.

“It has happened before that I had the best car overall but was still not the champion,” said Raikkonen. “There are so many little things that have to go in the right direction for you (to win the title).

“It’s pointless to think about the championship. Let’s try to do our job well, and see if that’s enough,” the self-described ‘iceman’ added.

Michael Schumacher has been pipped at the post in the race to be the world’s richest sportsman.

According to the Sunday Times’ annual listings, the seven time world champion’s (US) $823 million in career earnings is beaten only by golf legend Tiger Woods.

American Woods has earned $869 million in his own ultra-successful career, the newspaper found.

And the Sunday Times said the pair have each earned hundreds of millions of dollars more than other high-earning sportsmen, including Michael Jordan ($516m), Roger Federer ($316m) and David Beckham ($258m).

F1′s two other representatives, Fernando Alonso and Kimi Raikkonen, were way down the top-twenty list, with their respective earnings at about $161 million apiece.

McLaren’s world champions Lewis Hamilton ($89m) and Jenson Button ($85m), meanwhile, appear only on the list for British sportsmen, and they are both outpaced by the $129m earned by former Ferrari driver Eddie Irvine mainly through property investment.

However, Hamilton and Button have each earned more in their careers than David Coulthard, Nigel Mansell, former BAR boss David Richards (all $80m) and Sir Jackie Stewart ($67m).

Those earnings, however, are all dwarfed by Bernie Ecclestone’s estimated $4 billion, although the 81-year-old F1 chief executive does not appear at all on the list of the world’s richest overall.

That list is headed by mega-earners like Sauber sponsor Carlos Slim, who according to the Sunday Times is worth $71 billion.

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.

F1 figures have mixed feelings after this week’s Mugello test.

Amid speculation the Ferrari owned circuit would like a spot on the race calendar, it emerged that the famous Maranello based team pushed hard for the Tuscan facility to host the first in-season test in many years.

“It’s very beautiful and the food is very good,” said Red Bull team boss Christian Horner, “but we are spending a lot of money and honestly we didn’t feel the need to come here.”

Indeed, the only circuits comparable to high speed Mugello on the F1 calendar are Monza, Spa and parts of Silverstone.

And testing at Barcelona prior to next weekend’s Spanish grand prix would have made infinitely more logistical sense.

Lotus team boss Eric Boullier said Mugello was “money spent needlessly”.

Of course, those in the Ferrari camp thought differently.

“I would do more tests during the season,” said Fernando Alonso. “One lap here is worth 100 at other places, without considering that one day here is worth a year’s work on the simulator”.

But Mark Webber said Mugello is too fast for a decent test circuit, but he was among those who enjoyed the layout.

And the Australian couldn’t understand McLaren’s opposition, which extended to both Lewis Hamilton and Jenson Button giving up their running to test drivers.

“It was an absolute no-brainer for (Sebastian Vettel and I) to be here,” said the Red Bull driver.

“Mileage is so limited these days that it’s good for me to be in the car. Any chance we get to drive the car in the real world, we’ll do it,” added Webber.

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.”

F1′s new face of 2012 is polarising the sport.

It seems teams, drivers and spectators alike either love or hate the new great influence brought largely by Pirelli’s new generation of tyres.

An admitted critic is Michael Schumacher.

“It’s a 1000 piece puzzle that you need to put together at each race,” said the seven time world champion, according to Auto Motor und Sport.

Not for three decades have four different drivers driving for four different teams won the opening four grands prix of a season.

“From the standpoint of competition,” wrote Livio Oricchio in O Estado de S.Paulo newspaper, “there is no doubt that the Pirelli 2012 generation meets fully the objective of promoting the show.

“But if you think purely about the engineering challenge that is formula one, and the genius of the people and the immense financial and technical resources needed for success, the tyres have now taken on such an importance that the results don’t seem compatible.

“Myself, and many in formula one, hope the new versions of tyres that Pirelli is developing returns a little more predictability in terms of how they behave, without affecting the show too much.”

For now, however, the teams need to put their puzzles together, and that will undoubtedly be the focus of this week’s three-day in-season test at Mugello.

“He who understands the tyres first,” McLaren team principal Martin Whitmarsh astutely noted, “will have a huge advantage in the world championship.”

A broad understanding is already developing, including why 2012 winners Jenson Button, Fernando Alonso, Nico Rosberg and Sebastian Vettel won from the very front of the field.

“When you’re in a battle, you can’t take the lines that are best for the tyres,” said Mercedes’ Ross Brawn.

All eyes are now turning to Mugello, where the understanding will continue.

“These test days could change the balance of power in formula one,” Norbert Haug predicted dramatically in Bild newspaper.

Not everyone is enthusiastic, however, including McLaren who oppose the Mugello test on cost grounds.

Williams’ chief engineer Mark Gillan agrees: “The days of test teams are gone, so this is not logistically easy,” he is quoted by Germany’s Sport1.

Bruno Senna added: “Mugello is not an ideal test track, as it’s very different to most of the tracks that are on the calendar.”

Lewis Hamilton is rethinking McLaren’s scheduled approach to the rare and crucial in-season test at Mugello next week.

The British team announced last week that both Hamilton and his teammate Jenson Button would sit out Mugello, so that testers Gary Paffett and Oliver Turvey can run over the three-day session instead.

But that was before Bahrain, where McLaren’s early-season upper hand vanished, leaving the drivers and team members scratching their heads over the way the MP4-27 ate rapidly through the Pirelli tyres.

“It (the Mugello schedule) might change,” British newspapers report Hamilton as saying.

“I need to get back in the car. We need to figure out why the tyres are going off.

“If there are other things to test or ways to figure it out, I will be the one to do it, not let someone else do it,” said the 2008 world champion.

A McLaren source indicated that if Hamilton wants to test in Italy, the programme will be altered to accommodate him.

Button, however, appears unavailable to test, as he is scheduled to attend a promotional team event in Budapest early next week.

Tyres. The political dramas aside, that word utterly dominated the Bahrain grand prix weekend.

Afterwards, Michael Schumacher admitted he was “unhappy” with the situation.

“Sometimes we are driving only 60, 70 per cent through the corners,” he is quoted by Bild newspaper.

Pirelli did not take the criticism lightly, insisting it has made Canada 2010-style, heavily degrading tyres to order, for the benefit of the ‘show’.

Motor sport director Paul Hembery on Monday ‘re-Tweeted’ a message from a follower accusing the seven time world champion of having thrown “his toys out of the pram”.

Moreover, Pirelli said Bahrain is perhaps “the most demanding” on the entire calendar when it comes to degradation.

“As a result, knowing how to manage the tyres and contain thermal degradation was a vital skill” on Sunday, the Italian marque said in a statement.

On Twitter, The Times’ correspondent Kevin Eason called Bahrain an “excellent race, although I am not sure we haven’t moved from tyre management to lottery”.

The roulette wheel didn’t spin up for McLaren – the team with arguably the best overall car so far in 2012 – on Sunday.

“Nobody has added a second to their cars in just a week after China,” lamented Jenson Button, “but here we were a second off the pace.”

His boss Martin Whitmarsh told Auto Motor und Sport: “Maybe it was the pressures, maybe the temperatures. We really don’t know.”

The German reporter said Whitmarsh’s comment indicates an “uncomfortable realisation” for such a scientifically meticulous team.

Whitmarsh agreed: “It is now more important to understand the tyres than to find a bit more downforce.”

The tyre marque’s test driver Jaime Alguersuari told Mundo Deportivo newspaper that Pirelli deserves credit, not criticism.

“Pirelli is largely responsible for making F1 the most spectacular it has been in a decade,” said the young Spaniard.

F1′s surprise 2012 season has kept on bubbling in Bahrain.

It is a measure of the excitement and unpredictability of the new championship that, just days after some media said the reigning title winner was in ‘crisis’, Sebastian Vettel won from pole and took the lead of the 2012 points standings.

But the German only narrowly beat the returning 2009 world champion Kimi Raikkonen, with Lotus also completing the surprise podium as Romain Grosjean sampled the sport’s prestigious rostrum for the very first time.

Vettel leads the championship by 4 points from Lewis Hamilton, who finished just eighth.

Red Bull also leads the constructors’ chase, by 9 points from McLaren.

Vettel is the fourth different winner in F1′s four races so far this year, following Jenson Button, Fernando Alonso and Nico Rosberg.

It is his first win since India last year.

“How many good stories can we have in formula one in terms of the racing?” David Coulthard said on BBC television. “We’re only four races in and we’ve had such a mix of winners.”

Jenson Button doubts other teams will be pushing too hard to rush a Mercedes-style ‘double-DRS’ to their 2012 package.

The F-duct-style concept is, so far, the highest profile innovation of the season.

So with the FIA declaring it fully legal, and Nico Rosberg breaking through with his maiden pole and win in Shanghai last weekend, it seems a no-brainer that the other teams will now be following suit.

But McLaren’s Button doesn’t think so.

“I really don’t think it’s giving them that much — I think they’re just quick,” he is quoted by the BBC.

“From all our simulations, we don’t think it’s a massive margin at all. It’s a great invention on their part, but our DRS system is very good so I don’t think it’s giving them much over us.

“Obviously nothing in the race and in qualifying it’s minimal,” said Button.

His teammate Lewis Hamilton thinks the fastest cars so far are the Mercedes, the McLaren and the Red Bull.

“The Mercedes I think is now the quickest — particularly over one lap,” said the 2008 world champion.

“Not sure they are quickest in race pace. I think the Red Bull is probably the quickest in race pace. We have shown we have good qualifying pace and race pace.

“We are there or thereabouts and we have as good an opportunity as anyone.”
