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.

A new wheel nut design was the cause of Felipe Massa’s pitstop problem that cost the Brazilian fourth place at the recent German grand prix.

Massa entered the pits ahead of Red Bull’s Sebastian Vettel but a delay cost him the place to the world championship-leading German.

Ferrari’s head of track operations Diego Ioverno explained that the team, in the race for faster pitstops in the no-refuelling and multiple tyre-stop era, has been experimenting this year with new methods and equipment.

He said that at Silverstone, a new wheel nut design contributed to Ferrari performing the fastest overall pitstops.

“Then in Germany we were again using this new wheel nut, which does work better, but the system is still not perfect and, at Felipe’s last tyre change, we lost the connection between the wheel nut and wheel nut gun, which cost us around one and a half seconds,” he confirmed.

“So we have more work to do on perfecting it.”

Extreme wheel nut and hub designs in 2010 are contributing to failures, according to Germany’s Auto Motor und Sport.

The specialist magazine said technical solutions to speed up pistops this year are related to the most recent failures seen on the Red Bull and McLaren cars last week in Barcelona.

McLaren boss Martin Whitmarsh confirmed this week that a wheel rim failure due to “human error” caused Lewis Hamilton’s deflation and crash on the penultimate lap.

Auto Motor und Sport claims that a mechanic had pulled his gun off the wheel too soon during the pitstop, with Whitmarsh now confirming that the nut subsequently “loosened slightly”.

“The magnesium part heated up and eventually broke,” added the Briton.

Meanwhile, Red Bull’s Vettel finished the race at the Circuit de Catalunya third, but without touching the brakes in the last dozen laps.

Auto Motor und Sport said the left front brake disc was longitudinally broken, with the team reportedly believing vibrations caused the failure.

The magazine speculated that, as was also the cause of his Melbourne problem – and Michael Schumacher’s retirement in Malaysia – a wheel nut not fitted tightly enough at the pitstop was at the heart of Vettel’s failure.

Martin Whitmarsh has confirmed that a failed wheel rim caused Lewis Hamilton to crash on the penultimate lap of last weekend’s Spanish grand prix.

Shortly after the Briton’s sudden tyre deflation, the McLaren team boss speculated that “debris” rather than an actual tyre problem probably caused the accident.

Bridgestone’s initial analysis was similar, but it did not stop some pundits from hinting that Hamilton’s aggressive driving style might have been a contributing factor.

But the damaged parts were returned to Woking for analysis on Monday, and Whitmarsh confirmed on Tuesday that a wheel rim failure looks the likely cause.

“The rim failure is being investigated,” he told reporters during a teleconference.

“It could be debris related, it could be an issue of deflection, or it could be a lack of tightness in the wheel nut, which allowed some flexing.

“What we know is the rim failed, probably human error somewhere in the process caused it, and that led to a deflation and the accident,” Whitmarsh added.

Apr.30 (GMM)  Drivers’ and constructors’ championship leaders McLaren are also winning the race as F1′s most reliable team.

The British outfit, whose Jenson Button leads the drivers’ table by 10 points over Mercedes’ Nico Rosberg, completed every single lap with both MP4-25 cars at the initial Bahrain, Australian, Malaysian and Chinese grands prix.

In second place, a 100 per cent record for Ferrari was tarnished only by Fernando Alonso’s engine failure in the closing stages in Malaysia.

Red Bull is third with a 92.4 per cent finishing record in 2010, despite the RB6 appearing to have suffered from several reliability glitches so far.

In fact, Sebastian Vettel’s wheel nut problem in Melbourne was the team’s only DNF, while teammate Mark Webber has completed all four races within the top 9.

Similarly, only one Mercedes car – Michael Schumacher’s in China – has failed to reach the chequered flag, but the German team is fourth in the list with a 89.2 per cent record due the stoppage occurring early in the race.

Williams’ single DNF culminates in a 86 per cent reliability record because Nico Hulkenberg was taken out on the first lap in Australia.

Renault is sixth of the ten teams with 75.1 per cent, for while Robert Kubica has finished every race with the R30, rookie Vitaly Petrov’s first race finish was in China.

In Bahrain the Russian damaged the suspension by hitting a kerb too hard, in Melbourne he spun into the gravel, and in Malaysia he had to stop with a gearbox problem.

Impressively, the new team Lotus also has a 75 per cent finishing record, even though Jarno Trulli was not actually a classified finisher at Sepang because he was ten laps behind.

And in Melbourne, the Italian’s T127 was not even on the grid due to a pre-race hydraulics problem.

Toro Rosso’s Jaime Alguersuari has finished all the races, but teammate Sebastien Buemi was taken out on the first lap in both Australia and China — first by Kamui Kobayashi and then Vitantonio Liuzzi.

Force India is now increasingly mentioned as a serious F1 competitor, but its reliability record so far in 2010 is just 65.9 per cent.

Liuzzi crashed in China and had a throttle problem in Malaysia, while Adrian Sutil had a Ferrari engine problem in Melbourne.

HRT’s F1 career started badly with only one car crossing the line in the opening two races.

But the Dallara-built cars of Bruno Senna and Karun Chandhok both finished in Malaysia and China, giving the Spanish team a 65.2pc finishing record.

Virgin and Sauber are at the bottom of the pile, with Virgin achieving a mere 33.8pc reliability record with only Lucas di Grassi able to cross the line in Malaysia by aggressively saving fuel.

Sauber is last, with only Pedro de la Rosa recording a race finish in Melbourne for a reliability record of just 25.5 per cent.

“We’ve suffered too many reliability issues on both the chassis side and with our engines,” team founder Peter Sauber said on Thursday.

“That’s very unusual — we’ve always been one of the best teams in this respect over the years.

“We’ve closely analysed all the chassis-related problems and already put measures into effect.  Our engine partner Ferrari is doing the same,” he added.

Nico Rosberg achieved the first podium finish for the Mercedes GP Petronas team at the Sepang International Circuit in Malaysia today. Nico Starting from second place on the grid, but Nico lost a place at the start and was running in third position at the end of the first lap.

He made his sole pit stop on lap 22 where superb work from the team enabled Nico to gain over a second on the chasing Robert Kubica. From there, Nico drove a composed race to the chequered flag to secure third position and his third podium finish,

Michael Schumacher was out of the race when a wheel nut came off one of the rear wheels and forced Michael to retire on lap ten.

Nico Rosberg
“Its a fantastic result today to achieve our teams first podium at the home race for our title partner, Petronas. I want to thank the whole team for all of their hard work this weekend and over the winter. This result is the start of the reward for our efforts. Its a great feeling to be back up on the podium again and to have so much support from the Malaysian fans here. My start didnt go that well today as I had a bit too much wheelspin and once I was in third place, I knew it would be difficult to follow the leading cars. I struggled a little with the options in the first stint which allowed Robert to stay quite close but once we switched to the primes, I felt really comfortable and we could manage the race home to third place. This is a great end to a strong weekend for us. Were not quite where we want to be yet so we need to push on but Im confident that well get there soon.”

Michael Schumacher
“It was a shame that I could not finish the race but unfortunately the wheel nut on the left rear wheel was lost. The car suddenly became very unstable in turn six and I could hardly steer and had no drive left. I initially thought it was something to do with the suspension but after I stopped and had a look, it was evident that was a wheel nut missing. It is something very unusual to happen and in testing we never had problems so we have to look it. I would have obviously wanted to finish the race and I think it could have worked out quite reasonably well. But in the end that is motor racing, I remember that very well. It makes no sense to get angry about it, you have to accept it as part of the game and look ahead. At least Nico scored our first podium finish and I am happy for him and the team.”

Ross Brawn
“That was an excellent drive from Nico today and a first-class performance to secure his third career podium and the first podium for the Mercedes GP Petronas team. We are delighted to have achieved the first podium for the Silver Arrows here in Malaysia and to be able to share the rewards of our hard work with our title partner Petronas at their home Grand Prix. My compliments to Nico for an assured performance today and over the weekend. Michael was in a good position after the start and we were looking forward to having a good race on his side but unfortunately it wasn’t to be. The car lost a wheel nut which is a problem that we haven’t experienced before. The wheel nuts are double-checked on the grid so we will investigate and put in place the necessary solutions.”

Norbert Haug
“A great drive from Nico and our first podium after starting from the first row in our third race. The team had a first-class strategy and Nico did not put one foot wrong and secured this first and for us historic podium finish, at the home race of our title partner Petronas. Our gap to the two Red Bull-Renaults in front of Nico was still considerable and we all know there is more work to be done in order to catch up. However it looks like we are heading in the right direction and the point standings after three races dont look too bad. Sorry for Michael who had a great start and was positioned sixth when a wheel nut came loose which stopped his race. We will work hard and concentrated to make sure that our car will be fully reliable in the future and get quicker step by step. After Melbourne, Nico and the team performed again the quickest pit stop which is very rewarding for our guys and sometimes very important to get the right amount of World Championship points. Last but certainly not least congratulations to Sebastian Vettel and Red Bull Racing for their first and well deserved victory in 2010. Seb was the class of the field today.”
