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.”

F1′s next winner could be at the wheel of a black and gold car.

“I think Kimi (Raikkonen) will be the sixth different winner in the sixth race,” said Finnish commentator and former driver Mika Salo, to the MTV3 broadcaster.

Although the results in 2012 have proved impossible to predict so far, many paddock pundits expected Lotus’ E20 to be the car to beat last weekend in Barcelona.

“The big surprise was when Kimi didn’t win,” admitted former Ferrari driver Salo, referring to Pastor Maldonado’s victory for Williams.

Also confident about Lotus’ potential is Raikkonen’s teammate, Romain Grosjean, who finished behind the 2007 world champion last weekend.

“It’s good to be a little disappointed with third and fourth,” he told the French language RMC Sport. “It shows that as a team we are convinced we can win.”

According to the reigning world champion team Red Bull’s drivers, however, there is a downside to this year’s impossible-to-predict F1 landscape.

“Maybe we will see an HRT or a Marussia on pole in Monaco,” world champion Sebastian Vettel said, unenthusiastically and half-seriously.

Mark Webber insists that what has been described as the Pirelli ‘lottery’ might not be a good thing for the sport.

“I don’t know if they (the fans) will get sick of seeing so many different winners,” the Australian told Fox Sports.

“It’s nice to have different winners but also we want rivals.”

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.

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.

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”.

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.

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.

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.”

A third team has decided to join Red Bull in Abu Dhabi for the young drivers’ test.

Due to the calendar congestion at the end of this season, and also to cut costs, most teams have opted to drop the Abu Dhabi option in favour of testing young drivers in July, at Silverstone.

But Red Bull, and its second team Toro Rosso, are sticking with the original November plan, amid criticism July is too early to be assessing young drivers.

McLaren is now following suit.

“Our plan at McLaren at the moment is to test in Abu Dhabi,” said the British team’s sporting director Sam Michael, who said another factor against Silverstone is that teams are only half-way through their engine mileage allocations in July.

“Engines is a significant factor,” the Australian explained.

“If you want to test at the end of the year, you have so many part-mileage engines that all have a little bit of mileage on them so you can effectively do it for free, in terms of your race engines,” said Michael.

“If you try and do that in the middle of the year, you can’t use your race engines so you have to prepare a special test engine.”

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.”

Ferrari’s heavily upgraded F2012 has caught the eye of reigning world champion and last-start winner Sebastian Vettel.

The famous Italian team and its lead driver Fernando Alonso have tried to play down the improvements made to the recently struggling red car.

“It was good acting,” said Brazilian newspaper O Estado de S.Paulo’s correspondent Livio Oricchio on Friday.

“The truth is that Ferrari have debuted a new car. Almost everything is different.”

Red Bull’s Vettel has spotted the same thing.

“If you ask me, Ferrari are dangerous,” Bild newspaper quotes the German as saying on Friday.

The ‘B’ Ferrari features new front and rear wings, floor, sidepods, engine cover, exhaust and brake ducts.

“A total reconstruction for a million euros,” said the newspaper.

Alonso was quickest on Friday morning in Barcelona but then a long way down the order in P2. He played down his victory chances.

But Vettel’s boss Dr Helmut Marko insists: “They (Ferrari) have become really fast.”

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.

Jaime Alguersuari has concluded he made “a mistake” to remain loyal to Red Bull late last season.

After testing Pirelli’s 2010 Renault car last week at Jerez, the Spaniard moved on to Barcelona to continue his work as a co-commentator for British radio.

However, he revealed recently that he might have been on the 2012 grid, had he not believed Red Bull executives who told him he would be at Toro Rosso this year.

“It was definitely a mistake not to negotiate with other teams,” said the Spaniard, “as I had the opportunity and declined offers,” he told Marca sports newspaper.

“I did that because I had loyalty to Red Bull.”

Asked if he has talked with anyone from Red Bull since his dismissal, the 22-year-old revealed: “The directors, no, the technical team, yes.”

It still pains him that, in explaining their decision, the Red Bull officials like Dr Helmut Marko insisted Alguersuari was not a potential winner.

“If you think that for six years they supported me then they changed their opinion overnight. One day you have a champion, the next you don’t,” he said.

Stefano Domenicali has ruled out responding to Ferrari’s latest crisis with the old ‘rolling heads’ technique.

One perception in the paddock is that the fabled Italian team, under intense pressure from the Tifosi and president Luca di Montezemolo, often reacts by emotionally shedding staff, with Aldo Costa and Chris Dyer the obvious recent examples.

So, having installed new faces including Pat Fry but still struggling with the latest F2012 project, will boss Domenicali set heads rolling again?

“Firing people is the work of two minutes,” he is quoted by Germany’s Auto Bild, “but this would not solve our problem.

“Instead I need to find new people who can improve the organisation and push the engineers to improve the car,” added the Italian.

In the meantime, there is no silver bullet.

“I am not happy with the F2012 project,” he acknowledged.

“But if you want to see the glass half full rather than half empty, then Fernando has done a great damage control and, with an improved car, he at least has the possibility to continue to fight for the championship.

“We have to improve,” Domenicali insisted. “I have asked my people to wake up and respond, and I will no longer hear excuses.”
