A lack of official information has triggered speculation about Ross Brawn’s health.

And another rumour is that his absence in Barcelona could be connected with Mercedes’ billion-dollar dispute with Bernie Ecclestone over the next Concorde Agreement.

The German squad announced on Thursday that Bob Bell is leading the team in Barcelona because regular boss Brawn is back in Britain on doctor’s orders.

Bild newspaper said the 57-year-old was given the advice in hospital earlier this week, following a dizzy spell at his home in England.

“It’s more than the flu,” chief executive Nick Fry is quoted as saying, “but I can assure you that it’s nothing life threatening.”

Indeed, a spokeswoman told us on Thursday that Brawn will be back to work at Monaco in a fortnight.

For Spain, Brawn will watch the action on television.

“We will still keep in touch,” Michael Schumacher revealed. “Ross cannot be replaced. That’s simply impossible.”

After Sebastian Vettel’s first win of the season in Bahrain recently, Red Bull could now maintain its grip on 2012.

That is the claim of the legendary triple world champion Niki Lauda.

Red Bull has been the dominant force since late 2009 and 2010, and Vettel was untouchable last year as he successfully defended his drivers’ championship breakthrough.

But four different teams have won so far in 2012, and only the last of them were Red Bull and Vettel, as the energy drink-owned team’s superiority appeared to have waned.

After Bahrain, however, Red Bull and Vettel are back, Lauda told Germany’s Auto Bild Motorsport.

“In Bahrain, they got the car and the tyres right for the first time, and they won,” said the Austrian.

“They will have improved the car further in Mugello, so I see enormous potential for another dominant season,” he added.

Lauda acknowledged that the blown diffusers of the past seasons was Red Bull’s “great strength”, and now that is gone.

“Nevertheless, Red Bull is the team to beat,” he insisted.

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.

Lotus is grappling with a major problem less than one month before the start of the 2012 season.
The former Renault team has sensationally abandoned this week’s Barcelona test and returned to its Enstone headquarters, after an unspecified chassis fault was detected on the new E20 car on Tuesday.

“We’ll put the right measures in place and we will be able to fix the problem before next week,” said technical director James Allison.

But Gary Anderson, formerly the designer of Jordan and Jaguar cars, believes Lotus is playing down the problem.

“You would have thought they could have fixed it overnight — chassis are made of carbon fibre composite so you’d be looking to bond new strengthening parts on,” he told the BBC.

“In my experience, if you can’t do it in 24 hours, I don’t think you can do it at all. I wouldn’t be surprised if this meant they needed a new chassis, which would make it touch and go for the first race.”

Germany’s Auto Motor und Sport thinks Lotus did not experience the fundamental problem at Jerez last week because the Circuit de Catalunya is a much more demanding circuit.

Meanwhile, Red Bull’s world champion Sebastian Vettel was Tuesday’s fastest as the second of three group tests began, but he admitted Lewis Hamilton – in the new McLaren – was also impressive.

“Ferrari is a bit of a secret at this stage and nobody knows whether they are really good or really bad,” admitted the German.

A spokesman has confirmed reports that aspects of Korea’s new formula one track are not completed.

The FIA’s Charlie Whiting this week approved the Yeongam venue ahead of the inaugural race in less than a fortnight.

But media reports have indicated that safety requirements and the asphalt aside, the entire venue is not finished.

“Landscaping work to the surrounding area and parking lots still remains to be done,” a spokesman for organisers KAVO told the Korea Herald.

“But we are finalising last-minute touches and can be ready on schedule,” he added.

After the weekend’s Japanese grand prix, the F1 teams’ equipment and cars are already en route to the facility 320 kilometres south of Seoul.

Red Bull’s Helmut Marko admitted the team is slightly worried about the layout, with the curvier sections punctuated by straights not suitable to the RB6′s Renault engine.

“One of them is the longest straight on the calendar,” he groaned, according to Auto Motor und Sport.

Nico Rosberg, however, expressed concerns that the crucial top layer of track has only just been laid.

“The only concern is the new asphalt,” the Mercedes driver is quoted by Welt newspaper.

The media report recalled June 1985, when the Belgian GP at Spa had to be postponed for months because the new asphalt surface disintegrated.

Heikki Kovalainen made the Grand Prix of Singapore at the end once more exciting and put out his blazing Lotus itself
The air seemed to be already out of the Grand Prix of Singapore, as Heikki Kovalainen in the penultimate round again caused a drama. Because after a light touch with the Toro Rosso of Sebastien Buemi, he was suddenly slow – and in the last sector ignited the back of his Lotus!

Kovalainen not turned off the box, but drove over the finish line. However, he was not here for an additional round for the final result was as suspected at first: “I wanted to with such a car will not go into the pit lane, because that would put many people Instead, I saw a fireman at the start and finish and stayed. there are, “he describes the exciting incident.
Curious: Kovalainen rose calmly from the car that was burning brightly in the rear, and still had the overview, to make themselves rich on the pit wall by a Williams mechanic with a fire extinguisher so that it could even lend a hand! “Something always looks dramatic,” he grins. “The car is a bit damaged, but at least no one was injured. That’s the main thing.”
Given that reasoning, it is unlikely that the race stewards will issue a penalty against him. Usually, it is well known, not allowed to drive on with an obviously badly damaged car – especially not when the pit exit would be located on the road. But Kovalainen reasoning makes sense, because it was so actually less risky.

By the way: through the smoke on the finish line and the yellow flags came Sebastian Vettel in the last round again threatening close to leader Fernando Alonso. Alonso, however, kept a cool head and saved his second victory in Singapore over the distance.
