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

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

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

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

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

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

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

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

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

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

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

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 was a breakthrough for Mercedes and Nico Rosberg, but the Chinese grand prix was a “difficult day” for Michael Schumacher.

That is the admission of Shanghai winner Rosberg, whose first race win after more than 100 attempts also delivered German marque Mercedes’ first works victory for more than half a century.

“I felt he was very happy for me,” Rosberg told Auto Bild Motorsport, when asked what seven time world champion Schumacher’s reaction was.

Since returning to F1 more than two years ago, 43-year-old Schumacher – although stepping up his pace in 2012 – is yet to finish a single grand prix on the podium.

Nonetheless, he offered his congratulations “very, very warmly” after China, Rosberg revealed.

“At the same time I know that it was, of course, a difficult day (for him),” he admitted.

Norbert Haug, the team’s motor sport director, recently sounded inclined to keep Rosberg and Schumacher together beyond 2012, despite the fact the older and more famous German’s contract is ending.

He insisted there is “nothing negative” about their relationship.

As for ongoing rumours that Schumacher still enjoys number one status, Haug called that idea “absolute nonsense”.

“Do you know what Nico said to me, before Michael came? He said ‘If you can get Michael (on the team), then try everything for it’.”

Rosberg has not changed his tune.

“There was never a situation in which Michael got anything before I did,” he confirmed.

Pirelli test driver Lucas di Grassi has defended the F1 tyre supplier following Michael Schumacher’s criticism.

Schumacher attacked the Italian marque’s 2012 product after the Bahrain grand prix, complaining that the tyres wear so fast that drivers often have to take corners at half-pace like the safety car.

“In some ways he’s right,” Brazilian di Grassi, who along with Jaime Alguersuari tests tyres for Pirelli, is quoted by Globo.

“You can’t go at 100 per cent all the time because the current tyres are designed to highlight the strategy during the races.

“Drivers have to think more about what part of the race to make best use of the tyres,” said the former Virgin driver.

Di Grassi, 27, credited Pirelli for the exciting races seen so far in 2012.

“The championship is very balanced, which is good for everyone, especially the public,” he said.

“It’s partly because Pirelli has been able to use the data it collected last year and make good decisions for this year,” added di Grassi.

Also with a view contrary to Schumacher’s is the seven time world champion’s own teammate, Nico Rosberg.

“F1 has become more interesting,” said the Shanghai winner, “as everything has been shaken up — it’s much better than the same cars and drivers always driving away from the front,” he is quoted by German media.

“Due to the tyre situation, the races have been very varied, which is an extraordinary challenge but also very exciting. And we have to get used to it,” added Rosberg.

Red Bull has poured cold water on expectations the reigning back to back world champions could be set to resume their reign over formula one.

After a victory drought spanning the opening three races of the 2012 season, Red Bull broke through with Sebastian Vettel’s familiar win-from-pole triumph in Bahrain last weekend.

It means he has leapt to the top of the drivers’ standings, while the Milton Keynes based team is now 9 points clear of its nearest rival, McLaren.

“King Sebastian is back!” exclaimed the authoritative Italian newspaper La Gazzetta dello Sport after Bahrain.

“Vettel and Red Bull dominated like old times.

“They have worked hard in recent weeks to have a great car again, so it will be difficult once again to take the throne from Sebastian.”

The energy drink-owned camp, however, is not so bullish.

“To predict our performance in Bahrain just a week after what happened in China would have been tricky,” said team boss Christian Horner, referring to Vettel’s fifth place in Shanghai.

“I am sure that with 16 races to go, we are going to see a lot more variation.”

24-year-old Vettel agrees that, despite the familiar pole-and-victory in Bahrain, 2012 is not the same as 2011, when the RB7 car utterly dominated F1.

“We’re not as confident as we used to be,” he is quoted by the Sun newspaper, “so small things can make a difference in qualifying and have a big impact on the race.

“We’ve only had four races but I’m not entirely happy with where we are.”

Vettel will be back in action next week, when F1 moves to the Mugello circuit in central Italy for a rare in-season test.

“In Italy we’ll be able to test and evaluate a lot of things and get the car in a happier place for Barcelona,” he said.

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.

Bahrain 2012 is all about tyres, said Shanghai winner Nico Rosberg on Friday.

More specifically, Germany’s Auto Motor und Sport revealed that the key to victory this weekend will be the management of Pirelli’s rear tyres in the hot Sakhir desert.

“If you stand on the gas too much, the tyres are too hot already,” said Force India’s Nico Hulkenberg.

Rosberg won in cool China and was fastest in Friday’s hot second practice session in Bahrain, but there remains a question mark about the way his Mercedes uses its tyres.

Referring specifically to Bahrain, the German admitted: “It’s tricky to keep the rear tyres alive.

“It will have little to do with fast driving — it’s more like Le Mans or something.”

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.”

Emerson Fittipaldi, the successful Brazilian driver of the 70s, has tipped Jenson Button as a strong contender to match his own tally of two world championships come the end of the 2012 season.

“From what I can see, it will be between Jenson Button and Nico Rosberg. They are the big favourites,” the 65-year-old is quoted by Brazil’s Globo.

“Obviously, if Ferrari improves, then Fernando (Alonso) is spectacular. Lewis Hamilton is very aggressive, very fast, but I think Jenson is very clean, easier on his equipment and the tyres.

“I think this (season) is best suited to his (Button’s) style,” said Fittipaldi.

McLaren’s Button, however, is not so sure, pointing out the unusually closely-packed 2012 grid, and the big role being played by the Pirelli tyres.

“You don’t know who is going to be your main opponent on Sunday,” Auto Motor und Sport quotes the 2009 world champion as saying.

“It could be Red Bull, or Mercedes, or Ferrari, or Lotus or even Sauber,” he smiled. “So who do you focus on for the strategy?”

This weekend, F1 will find out whether the hot track temperatures in Bahrain will reshuffle the order. Button laughed when asked if it means McLaren will pull ahead of Mercedes this weekend: “We hope so, but we don’t know!”

Michael Schumacher, whose career stretches all the way back to 1991, said 2012 is the “closest season I’ve experienced”.

As for what happened in China, where his Mercedes teammate Nico Rosberg won from pole for the first time, the German admitted: “I really didn’t think that would happen.”

It is for that reason that Button warned against writing off F1′s reigning champions, Red Bull and Sebastian Vettel.

Vettel said he is not expecting “miracles” in Bahrain, but he also said: “We still haven’t seen a team that is clearly above all the others.

“Maybe McLaren is the most consistent, but they didn’t do what you expected them to do in Shanghai …”

Statistically, the Chinese grand prix raced straight into the history books as one of the most exciting formula one events of all time.

“For me, we are having some of the best races in formula one history,” agreed Jenson Button after finishing Sunday’s Shanghai race behind Nico Rosberg.

Finland’s Turun Sanomat newspaper reports that only three grands prix in the history of the sport played host to more individual overtaking moves.

The report said there were 72 passes in total on Sunday, not including the first corner of the race. Seven of the moves were on Kimi Raikkonen on one lap, after the Lotus driver’s Pirelli tyres gave up the ghost.

Last year in Shanghai, there were 63 passes. So far in 2012, there were more overtaking moves in China, Malaysia and Australia compared to the same races last season.

Canada 2011 still stands as the site of the most passes during a single grand prix, at 89.

In second place are the 1983 US grand prix and the 2011 Turkish grand prix (79 passes), followed by China last weekend.

McLaren team boss Martin Whitmarsh is celebrating the spectacle of the 2012 season so far.

“Who’s going to predict who will win?” he said, referring to this weekend’s grand prix in Bahrain. “I won’t.

“We’ve had three very different races and I think we are going to have potentially 20 very different races this year.”

More wins could quickly follow for F1′s newest race victor, Nico Rosberg.

The Mercedes driver began the 2012 season with more than a century of races under his belt, causing some pundits to predict he will never taste winning champagne.

But he broke through in China just a day after his maiden pole.

“I took 113 (races to win) and he’s on 111,” 2009 world champion Jenson Button smiled in Shanghai.

Niki Lauda thinks Rosberg’s next wins will be easier.

“It (winning) gets easier,” the Austrian legend said in China late on Sunday, “because he know you can do it, and you’ve proved it.

“The next victories come quite quickly,” Lauda told the German broadcaster RTL.

Patrick Tambay won just two grands prix in consecutive seasons, 1982 and 1983, but he said the first one – achieved in Keke Rosberg’s championship year – came with “a sense of completion”.

“After that, things seem easier,” said the Frenchman, “especially so when you’ve waited 110 grands prix!

“It will feel like a relief,” Tambay told RMC Sport. “Now, he’s still young at 26 but with a lot of experience; he has everything he needs to reproduce this victory.

“The first is the most difficult.”

However, Tambay thinks Rosberg has a fight on his hands if he thinks the Shanghai victory is a springboard to a potential championship challenge.

“I see the McLaren as the best car of the season. They passed up a good opportunity for the (China GP) win,” he said.

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.”

Michael Schumacher could be the next silver-clad driver who takes a Mercedes to the top step of the podium.

His teammate Nico Rosberg dominated the Shanghai weekend and, at his 111th attempt, finally broke through with a maiden pole and win.

The much-younger German also dominated Schumacher, the 43-year-old, at Mercedes in the last two years — ever since the seven time world champion returned to formula one in 2010.

But former Benetton and Ferrari title winner Schumacher appears much more on Rosberg’s pace this season, and in fact even solidly outqualified his 26-year-old teammate in Australia and Malaysia.

“It’s simple,” Schumacher told Brazil’s O Estado de S.Paulo.

“The way I can drive this car is much more how I have driven a car throughout my whole life.

“If you look at my driving today and compare with ten years ago, not much has changed,” said the famous German. “But if you look at 2010 and 2011, my arms never stopped working.

“It wasn’t my way to drive,” insisted Schumacher.

Having followed Rosberg early in the Chinese grand prix – before his retirement – Schumacher admitted that he could not quite match the leading pace.

But, despite not standing on a podium even once since his F1 comeback, he has now smelled that a victory is close.

“It will be the same feeling as when I went to the podium for the first time with Benetton, and Ferrari,” Schumacher predicted.

“When I started with those teams, we were far away from being able to think about it. But after a lot of work, I would say years – just as now with Mercedes – we had reached the stage of being able to fight.

“Most people have no idea how many things need to be changed, how much effort and investment is required. At 43 I’m going through all of this again, but it’s because I really love what I do.”

Schumacher’s Mercedes contract expires at the end of this year.

“You might not believe it,” he responded, “but I’m so focused on developing this car that I don’t think about it.

“Later on in the season, of course, it’s inevitable.

“Of course it gives me great pleasure that we are starting to see the results of this great work. I am still perfectly capable of winning in formula one,” Schumacher insisted.

Despite winning in Malaysia last month, Fernando Alonso is expecting a miserable weekend in Bahrain.

On the back of his surprise Sepang victory, the Spaniard qualified and finished just ninth in China, and he is not expecting a better Ferrari until next month’s return to European grands prix.

“Obviously, this (result) does not leave me very optimistic for Bahrain, on a track where traction and speed are vital, exactly the areas where we are weakest,” said Alonso in Shanghai.

Even more bluntly, he said the Maranello based team is “far behind” the pacesetters because the F2012 has “big problems” in aerodynamics.

But the bright side, Alonso insisted, is that the field of 2012 is oddly tightly bunched.

“If we improve two, three tenths then we can jump several opponents,” he is quoted by Brazil’s O Estado de S.Paulo.

“The fight now is for fractions of seconds.”

After Ferrari and Sauber were quick in Malaysia, Mercedes’ Nico Rosberg dominated in China — but many in the paddock still believe McLaren has the quickest car overall.

Indeed, Jenson Button is ruing a team mistake – a cross-threaded wheel nut during a pitstop – that he says cost him a shot at Shanghai victory.

“There can’t be many more mistakes if you want to compete for a championship, definitely not,” he said.

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.”
