Marussia needs a KERS system to catch up with its direct rivals.

That is the admission of team boss John Booth, who told the Russian website championat.com that he is looking into adding the energy recovery technology to next year’s Marussia package.

“First of all, I want to say that while it is said it (KERS) is a ‘green’ technology, in reality it’s just a serious waste of money,” he said.

“But in our situation it’s time to start thinking seriously about KERS. Of the gap to Caterham, five or six tenths is due to KERS,” added Booth.

“So we are thinking seriously about it for 2013, but so far there is no decision.”

Both admitted the start of the 2012 season has been a disappointment so far for Marussia, which in its first two years was called Virgin.

He said the team has recently completed a phase of serious restructuring.

“We had a good team of people before, but now we have a good team of designers. Though we have been in F1 for three years, I have the feeling that we were actually born in July 2011.”

Both is undoubtedly referring to the split mid last year with former technical chief Nick Wirth, and the relocation to a new headquarters.

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.”

Last Sunday proved that Pastor Maldonado is no mere ‘pay driver’.

“If he was a fool, he would not be with us, no matter how much money he brings,” Sir Frank Williams is quoted by Brazil’s Globo Esporte.

Venezuelan Maldonado, whose links to the state owned oil company PDVSA and president Hugo Chavez controversially deliver many millions to Williams’ Oxfordshire based team, became F1′s fifth different winner of 2012 last weekend in Spain.

It has helped him to shake off the ‘pay driver’ insult, Williams insisting he is now a potential world champion instead.

“Without a doubt. He is very fast and makes no mistakes,” the newly 70-year-old Briton said.

Williams does, however, acknowledge that Maldonado’s money was a key factor in the decision to sign him.

“Yes, it was to some extent,” he said. “I don’t deny that. But he’s also a real driver. He fully deserves to be on the team, with or without money.

“The truth is that if you don’t have money, you don’t get to be in formula one,” added Williams.

Team shareholder Toto Wolff agrees: “If you want to race in GP2, you need a few million pounds. So, the drivers need not only to be fast and talented, but able to attract the sponsors.

“So let’s forget this thing about ‘pay drivers’,” he insisted.

Triple world champion Nelson Piquet, however, has some lingering doubts.

He ran Maldonado in his own GP2 team some years ago, and this week recalled a driver who was often “too aggressive” and made too many mistakes.

“We’re not talking about a guy who shone in his youth, like Nico Rosberg,” said the famous Brazilian, “or someone like Lewis Hamilton, who always had everything he needed thanks to Ron Dennis.

“In GP2, when you don’t stand out in your second year, you begin to be doubted. In Maldonado’s case, he only shone in his fourth year.

“Perhaps because of this he only made it to formula one as a paying driver, without having anything special, apparently. He was perceived as just a good pilot, but clearly no Alonso.

“Now he was at the right place at the right time but he still managed to beat Alonso in Spain as well as another world champion, Kimi (Raikkonen). So hats off to him.”

Spanish driver Dani Clos will step into the F112 for the first time on Friday to take part in the first free practice session of the Spanish Grand Prix which will take place at the Circuit de Catalunya. 23 year-old Clos will substitute teammate Narain Karthikeyan for that session and will join Pedro de la Rosa for the first 90 minutes of practice in Montmeló.

It will be history in the making for HRT Formula 1 Team at the Circuit de Catalunya since this will be the first time that two Spanish drivers hit the track forming a part of a Spanish team at the Spanish Grand Prix. It will be a moment to remember for Spanish motorsport and a great opportunity for Clos to prove his worth in front of his home crowd.

After having completed 377.67 kilometres at the helm of the F111 in the Young Driver Test in Abu Dhabi last November and having joined the team as an official test driver in February, Dani Clos will take another step on Friday and will fulfill another vital aspect of his testing role by completing his first laps at the wheel of the F112. A car that will be brining a series of aerodynamic upgrades for this important Grand Prix.

Dani Clos: “I’m delighted to have this opportunity. It’s something I’ve fought for all my life; to make my debut in Formula 1 and, above all, to be able to do it at the Circuit de Catalunya which is something very special for me. Besides, I’m extremely lucky to be able to do it with a Spanish team, alongside another Spanish driver who I admire and at home. I can’t ask for more! It’s the ideal situation and I’m proud to be where I am with the people who have always been with me and still are. I hope to extract a lot of data from this practice session, contribute with positive things to the team and do my job in the best way I can. I feel 100% ready and I can’t wait for the moment I step into the car and hit the track”.

Luis Pérez-Sala, Team Principal HRT: “I’m very proud and happy that this moment has arrived and that we’ve given Dani the chance to get in the car on Friday’s first free practice session at such a special and important Grand Prix as is a home Grand Prix. In this first contact he will drive next to Pedro de la Rosa and will have the chance to drive the new F112 for the first time. It’s an important session given the short amount of time on track that we have and more so when you take into account the various aerodynamic upgrades which we have brought. Dani is a great driver and I have no doubt that he will do a good job. Besides, this debut also represents another step forward in our desire for HRT to serve as a platform for young drivers to make it into F1”.

DANI CLOS – PROFILE AND CAREER SUMMARY

Dani Clos was born in Barcelona on the 23rd of October 1988. With a renowned trajectory in karting, Clos made his debut in single-seater racing in 2004 in Formula Renault Italia 2.0, going on to win the Championship in 2006. A year later he joined Renault’s F1 programme and took part in the Formula Three Euroseries. In 2008 he entered Williams F1′s young drivers’ programme and finished in 2nd in the 24H Barcelona race. In 2009 he made his debut in the GP2 series, with a 3rd place finish in Portimao being his best result. In his second year in GP2 he achieved his first win in Turkey alongside various podium finishes. Last year, Dani Clos took one win and two podiums in what was his third season as a GP2 driver. Also in 2011, he took part in the Young Driver Test in Abu Dhabi with HRT F1 Team, completing total of 377.67km in one day and leaving a very good impression on the team. In 2012, Dani Clos joins the HRT Formula 1 Team as its official test driver.

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.”

All this year’s title contenders know after four ‘flyaway’ races in 2012 is that they do not know what will happen in Spain next month.

“The only certainty is uncertainty,” read the German headline at Netzeitung.

With F1 generally regarded in the wider world as a sport with predictable results, this is an entirely new situation.

“The statistics show that it’s been nine years since there have been four different winners in the first four races,” said Ferrari team boss Stefano Domenicali.

Indeed, the famous Italian team as well as McLaren, Mercedes and Red Bull have won the opening races of 2012, and also with potentially winning pace have been Lotus and Sauber.

“More than that,” continued Domenicali, “you have to go back 29 years to find the last time four different cars won.”

One explanation is that F1 has never been more competitive, with plenty of well-oiled teams and no fewer than six world champion drivers on the grid.

But Domenicali thinks Pirelli is the dominant factor.

And not everybody is happy about that. Michael Schumacher told Bild newspaper that this year’s tyres degrade so fast that rubber “flies from the rim” if he pushes too hard in a corner.

“We drive around like the safety car. It is not a satisfying situation,” the seven time world champion said.

Pirelli’s motor sport director Paul Hembery is unimpressed with the rebuke, insisting that the Italian marque is only trying to “make tyres that make the races exciting”.

“We cannot take individual drivers into consideration,” the Briton insisted.

“It would be dead easy for us to make tyres that don’t break down. Then the top ten would also be the top ten in the race.

“But no one wants to see boring processions,” Hembery claimed.

Agreed the Swiss headline at Blick: “Pirelli is sweeping away the boredom”.

Indeed, not even the other Mercedes driver, Shanghai winner Nico Rosberg, agrees with Schumacher.

“It’s total chaos. You don’t know who is going to be fast at the next track,” he is quoted by DPA agency. “Formula one has become almost unlike any other sport.

“Yes, you cannot drive any laps any more at full throttle. Often, it’s like driving on ice. But that’s a big and an interesting challenge,” said the German.

Undoubtedly exciting for the fans, but the teams are having to adapt quickly. Italy’s La Gazzetta dello Sport said on Sunday that Vettel’s victory could mean Red Bull resumes its dominant grip on F1.

Dr Helmut Marko doesn’t think so. “We don’t even know who our opponents are!” he exclaimed.

The calamitous Bahrain grand prix saga has not jeopardised the island Kingdom’s future on the F1 calendar.

That is the strident claim of Bernie Ecclestone, after the F1 chief executive and FIA president Jean Todt displayed rare unity as they insisted the country’s civil and political problems would not affect the grand prix.

But amid the bubbling Bahrain saga, Ecclestone had suggested that Bahrain might face trouble when it comes to negotiating a new contract, with the existing agreement only set to extend for three more years.

However, when asked by Reuters if F1 is going to keep returning to Bahrain despite this year’s troubles, Ecclestone insisted on Sunday before leaving the Persian Gulf: “Absolutely. Forever. No problem.”

Like Todt, he even played down the damage done to F1′s reputation this weekend.

“I think it’s good because people talk about things, you know. You know what they say — there is no such thing as bad publicity,” said Ecclestone.

In truth, reputation damage has undoubtedly been done. But Roger Benoit, the veteran correspondent for the Swiss newspaper Blick, admitted he is dismayed with how politics interfered with sport so strikingly this weekend.

“On all continents, somewhere, all hell is breaking loose. And as a formula one reporter, you’re flying around this globe two or three times a year,” he wrote.

“We go to countries that are politically explosive. Where human rights are violated, where poverty reigns.

“But we hardly talk about it — not in China, India, Korea, Malaysia, Singapore or Brazil. In 2014, we’re going to Russia.

“Years ago, our circus happily danced around in apartheid South Africa, and the military dictatorship of Argentina.

“Formula one is pure entertainment. Detached from the problems of the world. But here, in Bahrain, every reporter entered the political field, whether he liked to or not,” wrote Benoit.

So that is why Ecclestone is unapologetic, after championing the Bahrain grand prix.

“Because, basically, the problems they have in Bahrain have nothing to do with F1,” the 81-year-old told El Pais newspaper.

“The relevant agencies gave the nod as far as security was concerned, and I think it is clear that they were not wrong.”

He also sees no problem with F1 being used as a political tool.

“Governments want to have an F1 race for the same reason as they want the Olympics. We come to agreements with the promoters and, if that’s good for the country, fine,” said Ecclestone.

Bernie Ecclestone on Sunday confirmed reports France is definitely heading back to the F1 calendar.

Reports earlier this weekend said authorities had “finally agreed” a figure for the sanctioning fee with F1 chief executive Bernie Ecclestone.

It is expected that the Ecclestone-owned Paul Ricard will share an annually alternating grand prix date with Belgium’s Spa-Francorchamps, beginning in 2013.

“Yes,” the 81-year-old Briton told French daily L’Equipe in the Bahrain paddock on Sunday.

“The deal is done,” said Ecclestone.

“We agreed the financial terms with the sports minister David Douillet, in my office on Tuesday.

“We are still discussing a few things about money: ‘You give me this, I want that’,” he added.

“But, for me, there is no doubt, we will sign it now,” said Ecclestone.

He said the outcome of the forthcoming presidential elections in France will not spoil the deal.

“Whatever happens, I don’t care,” said Ecclestone. “That’s a local issue that doesn’t concern me.”

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.”

Rubens Barrichello has revealed he feels partly responsible for Williams’ surge in form so far in 2012.

For the veteran Brazilian’s final season in F1 last year, the famous British team had its worst performance, scoring just 5 points and slumping to ninth in the constructors’ standings.

But already in 2012, just three races into the new season and with Barrichello’s departure one of many changes, drivers Bruno Senna and Pastor Maldonado have already scored 18 points.

“When I turn on the TV and see formula one and I’m not there, it is a very strange feeling,” he is quoted by Brazil’s Globo.

“But I’m not feeling it as a loss,” said Barrichello, who has moved to Indycar.

“Williams is doing very well and they deserve to be ahead. But I have no doubt, as well, that with a little more experience in that group, their cars would be even further forwards.

“All the work carried out for this (2012) car is a result of what we fought hard for last year,” Barrichello insisted.

“Bruno is already reaping a lot from being with an engineer who was mine, as I was an experienced driver who likes the technical side and we exchanged a lot of information.

“For Bruno’s future it is very good,” insisted the winner of 11 grands prix.

Barrichello also hailed F1′s newest winner, Nico Rosberg, who like the Brazilian toiled in the sport for years before breaking through with his first victory.

“Nico is one of those great talents who takes a long time to win a race,” said Barrichello.

“You know in your head what you could do in another situation, but anyway the lack of a win does become a mental setback.

“Afterwards you don’t improve as a driver, but it does take an elephant off your back,” he laughed.

Nico Rosberg’s F1 breakthrough proves he is ready to fight even for the world championship.

That is the view of former grand prix winner, team boss and co-owner Gerhard Berger, following Rosberg’s first pole and win in China last weekend.

“It surprised not me, but all the others who had doubted him,” the Austrian told Auto Bild Motorsport.

“It was about time. I was worried,” Berger smiled, “because I have always said I thought Nico was faster than Michael (Schumacher).

“Now he is finally where he has belonged for a long time — in the same league as Vettel, Hamilton, Alonso and Button,” he insisted.

“And when the (Mercedes) car is good enough, he is already ready for the world title.”

Berger, then as BMW motor sport director, said he was instrumental in 2002 in convincing Sir Frank Williams to give the then 17-year-old Rosberg his first F1 test.

Also welcoming Sunday’s breakthrough is Nelson Piquet junior, another son of a world champion who actually went to kindergarten with Rosberg in Monaco.

“It’s funny how in F1 things can take so long to happen,” the Brazilian told Globo.

“It took him more than six years to get his first victory, which for me is a long time considering how good a driver he is,” added Piquet, now in Nascar.

A support-race team and a respected journalist have become the next to pull out of this weekend’s highly controversial Bahrain grand prix.

The Porsche Supercup team MRS said its decision to skip the support race in the divided island Kingdom is the “first time in our history that we have had to cancel”.

“In the end we have the responsibility for our employees,” said team boss Karsten Molitor, citing security concerns.

Another withdrawal – joining the sacked Williams catering staff member, and the TV broadcasters Sky Deutschland, Fuji TV and MTV3 Finland – is the respected correspondent for O Estado de S.Paulo newspaper, Livio Oricchio.

“I have decided in agreement with Estado to not go,” he said. “We had the tickets for the entire season, except for Bahrain and the United States, because there was a doubt they would be run.

“Like many journalists, I will not be at Sakhir,” Oricchio admitted.

“I always believed that the race would not take place, and I’m still not 100 per cent sure that something will not happen that will lead the FIA or FOM to cancel.”

Indeed, following the sport’s decision to push ahead, the pressure on formula one to cancel at the eleventh hour has only intensified.

Nabeel Rajab, the leader of the government opposition group Bahrain Centre for Human Rights, admitted that the next protests – ‘three days of rage’, to coincide with the race’s three-day calendar – are aimed specifically at F1.

“We’re protesting to show anger at formula one for conducting the race here,” he is quoted by the BBC.

And the wife of a well-known jailed Bahraini activist who is on a long hunger strike, added: “I am not angry with the government… what makes me angry is people like Ecclestone who decide to come to Bahrain because he thinks everyone is happy.”

Italy’s La Stampa reports that F1 personnel have been advised to stay away from restaurants and shops, while “girlfriends and wives stay at home”.

That’s not entirely true, as Felipe Massa touched down at the airport on Thursday with his wife and baby son.

And Giedo van der Garde, the reserve driver for Caterham, said he has found Bahrain peaceful since his arrival on Wednesday.

“I’ve not been here long,” he is quoted by Auto Hebdo, “but everything seems quiet. Obviously, there’s a heavy police presence,” the Dutchman continued.

“But I haven’t seen any trouble or anything. Let’s hope it stays like that.”

Marco Canseco, the correspondent for the Spanish sports daily Marca, said he witnessed a “minor altercation” in the capital Manama on Wednesday.

“Then all the teams and everybody were able to get to the track for work without a hitch, the same on return,” he revealed.

Many are protesting the race going ahead on moral grounds, others due to security fears, whilst others fear for F1′s image.

“The ongoing debate about Bahrain is the only damage to the high gloss of the exciting 2012 season so far,” agreed Austria’s Kleine Zeitung newspaper.

Norbert Haug said he is proud Mercedes has reached the top of formula one in a short space of time and with a small budget.

The German carmaker’s works team is often lumped together with F1′s other grandees including Ferrari and McLaren, but Haug insists the Brackley based outfit is in fact “a small team, with a small budget”.

Mercedes’ competition boss, who on Sunday collected the winning constructors’ trophy on the Shanghai podium, also said some of the team’s rivals – undoubtedly Red Bull – “took five years to win”.

“We have done it in two and a quarter,” the German told the RTL broadcaster. “That’s not bad at all.

“And there are other teams that still have not made it.”

So is Mercedes now a contender for the world championship, despite Haug’s earlier protestations that the team needs a few more campaigns under its belt for that?

“It is too early to make a prediction,” he told Auto Motor und Sport. “I hope so, but so far we have seen three different winners in three races.”

The newest of those winners is Nico Rosberg, who along with Damon Hill and Jacques Villeneuve are the only sons of F1 drivers to have also gone on to win grands prix.

It is a good omen for Rosberg that both Hill and Villeneuve also won titles.

Rosberg’s former Williams teammate, Alex Wurz, has high praise.

“As a teammate (in 2007) he made my life difficult because he was such a fantastic qualifying driver. In the race it was then always okay.

“But for this (race win) he deserves praise,” Wurz told the Austrian ORF broadcaster, “because he did everything after his pole position also sensationally.”

But in Bahrain, there could be another winner, triple world champion Niki Lauda remarked.

“I have never before seen F1 as interesting as this,” said the Austrian legend. “Every race we see another winner.”

Bahrain protesters have stepped up their anti-grand prix campaign, with formula one vowing to push ahead with a race in the troubled island Kingdom next week.

After the FIA declared that the race is definitely going ahead, Bernie Ecclestone on Friday met with team bosses in the Shanghai paddock.

“There’s nothing (bad) happening. I know people who live there and it’s all very quiet and peaceful,” the F1 chief executive insisted.

Media reports, however, suggest otherwise.

Photos have emerged of protesters burning flags depicting Ecclestone’s face, whilst others marched in F1 overalls and helmets, carrying machine guns.

Anti-F1 graffiti, meanwhile, is sprayed on walls throughout the capital Manama.

Ecclestone, however, told the BBC late on Friday that the Bahrain protesters are “not protesting about formula one”.

So with the race still scheduled, are the teams feeling comfortable?

“All the teams are happy to be there,” insisted Ecclestone.

Commented Red Bull’s Christian Horner after the meeting with the F1 chief executive: “The FIA have obviously done their research and come out with a clear statement that as a team entered into the championship we respect.

“We’ll do our best to ensure that all our guys and girls are in a secure environment, but I don’t doubt that for a moment.”

Michael Schumacher has dismissed the attempt to have Mercedes’ innovative ‘double-DRS’ system banned.

Having twice previously rejected rivals’ claims the concept is illegal, the FIA late on Thursday threw out Lotus’ official protest.

Seven time world champion Schumacher, who drives for Mercedes, admitted in China he doubts Lotus really thinks the system breaches any rules.

“If someone has a good idea, we always have this sort of dispute,” the famous German told Bild newspaper.

“It (the dispute is) because it’s going to take too long for the other teams to do the same thing. It’s the normal game,” said Schumacher.

It is believed McLaren and Sauber are working on their own versions of the double-DRS, as are the reigning world champions Red Bull.

“We have been working on it for some time,” a Red Bull source told O Estado de S.Paulo’s Livio Oricchio, “but it’s not easy to get even two small tubes down the entire length of the car, front to rear,” he admitted.

Oricchio said Ferrari is also working on a version, to debut no later than next month’s Spanish grand prix.
