Angry students could threaten next month’s Canadian grand prix.

Protests in Montreal, regarding planned university tuition fee increases, have been turning increasingly ugly and even violent, involving the throwing of glass bottles and hundreds of arrests.

According to the French language La Presse newspaper, at least one student association has specifically threatened to disrupt the F1 race, scheduled for 10 June on the nearby Il Notre Dame.

“I cannot deny that we are following this out of the corner of our eye and will continue to follow it in the coming days,” admitted race promoter Francois Dumontier.

The report said students’ chants at recent demonstrations included references to the grand prix.

At a recent meeting, one association of students approved a resolution to adopt “a weekend of disruption” aimed at “the cancellation” of the race, which represents “sexist, non-environmental and elitist” values.

“It is not clear that we will be targeted,” Dumontier insisted, “but we are an international event and are ready with a safety plan ranging from dealing with simple mischief to a wider disruption.

“The grand prix is often targeted because we are a major event. We are not worried but we have our eyes open and will work with the public authorities,” he added.

Sauber has become the second formula one team to reveal a brush with Bahrain’s civil unrest.

Force India was involved in a Molotov cocktail attack earlier this week, resulting in two team members returning to the UK and Nico Hulkenberg and Paul di Resta sitting out the second practice session on Friday.

Now, the Swiss team Sauber has revealed it saw masked protesters throwing petrol bombs whilst returning from the circuit to their Manama hotel late on Thursday.

“At 20.50 the 12 mechanics, being on that minibus to the Novotel, noticed fire on the medial strip of the highway,” said spokesman Hanspeter Brack.

“On the opposite lane there was no traffic. The team members saw a few masked people running from there over to their lane where a bottle was burning as well.”

No one was hurt.

F1 chief executive Bernie Ecclestone on Friday played down the latest drama, accusing reporters of “wanting a story” and offering to ride in the cars with the frightened Force India team members if they are afraid of Bahrain’s night.

Bahrain’s Crown Prince on Friday ruled out cancelling the troubled island kingdom’s grand prix.

“I think cancelling just empowers extremists,” he told reporters, whilst standing alongside F1 chief executive Bernie Ecclestone.

Pressure on the race organisers, Ecclestone and the FIA to cancel the race has only intensified after Force India and Sauber revealed their brushes with petrol bombs.

“I can absolutely guarantee that any problems that may or may not happen are not directed at F1,” the Crown Prince insisted.

Ecclestone, meanwhile, pointed his finger at the media.

“There are other countries much higher up the priority list you should be writing about,” he told the scrum of reporters.

“Go to Syria and write about those things there because it’s more important than here.”

When asked about the violent clashes between Bahraini protesters and the police, Ecclestone said: “It’s a lot of nonsense. You guys love it.”

However, he did admit that going ahead with the race is “a little bit silly” for the Bahrain government because it gives the protesters “such an incredible platform”.

Force India deputy boss Bob Fernley has dismissed reports the Silverstone based team could pull out of the controversial Bahrain grand prix.

Two members of the team were allowed to return to Europe this week following a Molotov cocktail attack en route from the Sakhir circuit to the hotel.

There were high-level meetings involving Force India on Thursday, sparking speculation the entire team could follow its frightened members back to the UK.

But Fernley, admitting that security has been ramped up after the incident, is quoted by Express newspaper: “We are definitely taking part, that is decided.”

Bahrain’s information affairs authority also released a statement featuring quotes by Bernie Ecclestone.

“I have no knowledge of any teams planning to withdraw from the race and we are all looking forward to racing in Bahrain,” the F1 chief executive said.

According to Telegraph correspondent Tom Cary, however, another incident like the one involving Force India this week could force F1 to change its decision to go ahead with the race.

“If that happened again and someone was injured then that’s the nightmare scenario for organisers as it might push the teams over the edge,” he said.

Many drivers, like Kimi Raikkonen, have said the situation is normal this weekend in Bahrain, but Cary does not agree.

“Normally there would be PR events in town, you know, ‘meet the fans’ and that sort of thing but certainly as far as I’m aware there aren’t any of those happening,” he said.

World champion Sebastian Vettel said he will be happy when track action begins on Friday.

“I think it’s not a big problem,” the German said when asked about the security situation this weekend, “and I’m happy once we start testing tomorrow because then we worry about the stuff that really matters — tyre temperatures, cars.”

Earlier, Vitaly Petrov’s manager indicated the Russian would only travel to Bahrain if F1 could guarantee his safety.

“If it was dangerous they wouldn’t let us in,” the Caterham driver told The National in Bahrain.

“If they make sure nothing gets thrown onto that track to hurt us, then we’ll be fine. We are here; if it happens, it happens,” added Petrov.

In fact, almost everyone in Bahrain has been reluctant to comment in detail, but there is an obvious feeling of unease.

Peter Sauber told Blick newspaper: “I feel like a guest, and so it is not polite to criticise your host.”

But 1996 world champion Damon Hill allowed himself some criticism of F1, including the sport’s most powerful figures, Bernie Ecclestone and Jean Todt.

He pointed out that FIA president Todt has said “next to nothing” about the Bahrain saga.

“This I find baffling,” Hill wrote in the Guardian. “Surely it is possible to condemn acts of inhumanity without taking a side?”

As for F1 chief executive Ecclestone, who has consistently trivialised the Bahrain issue, Hill noted that “few” in the paddock “dare to publicly disagree” with the imperious 81-year-old.

“Perhaps we should (criticise him), instead of just muttering under our breath, scared of losing our passes,” said Hill.

Hermann Tilke, the German architect who designed the Sakhir circuit, sees the entire saga as a storm in a teacup.

“It is safe in Bahrain,” Tilke, whose company has an office there, told the Kolner Express newspaper. “I’ve never heard about any problems from our people.

“Of course there is some unrest, but it is protests, not civil war. As Bernie Ecclestone has said, we do sports, not politics,” he insisted.

“And if they demonstrate peacefully now, the media will report on it, so both sides benefit.”

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.

McLaren is not yet ready to roll out a Mercedes-style ‘F-duct’ to complement its highly competitive 2012 car.

Despite Mercedes struggling with tyres in the actual races so far, the W03 is a standout qualifying performer, thanks in part to the so-nicknamed front and rear ‘super-DRS’ system.

Red Bull, Lotus and perhaps even Ferrari are threatening to protest, but until now McLaren – with arguably the dominant package of the 2012 season so far – has stayed out of the argument.

“We don’t have a strong view one way or the other,” technical director Paddy Lowe confirmed during the regular Vodafone media teleconference on Tuesday.

The F-duct will remain a hot topic in China this weekend, with Lotus’ technical boss James Allison believed to be armed with two new arguments against its legality.

It was thought McLaren was quite advanced with its own version of the system.

But Lowe revealed: “Until we’ve got clarity it’s difficult for us to commit a huge about of effort in that direction. So that’s where we are at the moment.”

He steered away from suggestions Mercedes, including boss Ross Brawn, have flouted the “spirit” of the recent F-duct ban.

“There’s no such thing as the spirit of the rules,” insisted Lowe, admitting that if there was a ‘spirit’ of the DRS rule, the Mercedes system is “definitely” in breach.

“The debate around whether they can keep that system on the car is not about whether it is in that spirit or not, it’s about whether the text of the regulations means they can’t,” he explained.

Many F1 insiders are now expecting next weekend’s Bahrain grand prix to be called off.

“We’re not going to Bahrain, the decision will be announced soon,” wrote Livio Oricchio, the correspondent for Brazil’s O Estado de S.Paulo newspaper.

In the wake of the latest reports about the ongoing political situation inside the island Kingdom, Oricchio said he expects the news about the race to be known “today or tomorrow”.

He referred to the direct threat made by the protest organising group February 14th Youth Coalition, who said it could not “ensure the safety” of the sport’s travelling members.

A spokesman for the international group Human Rights Watch admitted it is worried.

“On the ground we see an increasing number of deaths, and serious injuries from tear gas and beatings,” he is quoted as saying by the BBC.

And the latest fears have been intensified by the explosion of a bomb that injured seven policemen on Monday, and news that a jailed activist on hunger strike is now close to death.

An unnamed team boss admitted he is worried about his employees “and their families”, but an advisor to Bahrain’s interior ministry tried to play down those fears.

“People can be assured that if problems arise, then there will be a plan to deal with that as there would be with any public event in the world,” former London police assistant commissioner John Yates told the Associated Press.

But even Bernie Ecclestone, who will be in China this weekend, could now be stepping back from the controversy.

“If the teams don’t want to go, then we cannot make them,” the F1 chief executive told the Times.

All the FIA has said is that it is “monitoring” the situation, with it believed that contingency plans are in place so that F1 can cope with a cancellation decision made as late as this Saturday or Sunday.

The Bahrainis, meanwhile, are confident.

“We anticipate formula one will continue and hope it will be a success,” said government spokesman Sheikh Abdulaziz bin Mubarak al-Khalifa.

The Bahrain circuit’s Shaikh Salman bin Isa Al Khalifa added: “The race is going ahead — there is no doubt about that.

“There are several reports doing the rounds that are saying a lot of things which are baseless,” he told the Gulf Daily News.

“We are ready and there is a plan in place to ensure the safety of the teams, officials and fans.”

In the case of Sauber’s clever exhaust solution, Red Bull simply rolled out a copy in the days before the 2012 season.

Writing in O Estado de S.Paulo, Brazilian correspondent Livio Oricchio said the Sauber philosophy makes ingenious use of something called the ‘Coanda effect’.

In the wake of the FIA’s strict clampdown on blown exhaust technology for 2012, the C31 uses the Coanda effect – named after Romanian aerodynamics pioneer Henri Coanda – to legally entice the flow of exhaust to the diffuser.

Ferrari is understood to be the next team set to follow suit.

Red Bull, Ferrari and Lotus, however, have a vastly different attitude when it comes to Mercedes’ clever F-duct, which uses the existing DRS rules to redirect air from the rear of the W03 car to the front.

The concept not only significantly boosts straight line speed but also improves handling.

The FIA’s Charlie Whiting has declared that Sauber and Mercedes are doing nothing wrong.

But the three aforementioned teams continue to rail against the F-duct, even leaving open the threat of protest ahead of the Chinese grand prix.

Red Bull’s Dr Helmut Marko explains: “Lotus, who are very responsible, have discovered two ways in which the F-duct is not in accordance with the regulations.”

So is the difference in attitude when it comes to the Sauber and Mercedes innovations actually about the ease in which they can be copied?

Oricchio quotes Red Bull’s Adrian Newey as having said in Malaysia: “In regard to the aerodynamic (F) duct of the Mercedes, and sending the airflow from the back to the front, it is necessary to review the entire project.”

Damon Hill has changed his mind yet again on the controversial issue of Bahrain’s return to formula one later this month.

Amid the debate about the island Kingdom’s return to the calendar in the wake of the cancelled 2011 event, the 1996 world champion said initially: “F1 must align itself with progression, not repression”.

But he changed his tune after travelling with FIA president Jean Todt to Bahrain, insisting the situation on the ground had changed since the 2011 protests.

“The grand prix is of huge economic importance to Bahrain. You’d almost be putting an economic sanction on Bahrain by pulling the race,” said Hill.

But the Briton has now changed his mind again, apparently after the latest reports of violence on the streets and the reaction in the international media.

Hill is quoted by the Guardian newspaper: “It would be a bad state of affairs, and bad for formula one, to be seen to be enforcing martial law in order to hold the race.

“Looking at it today you’d have to say that (the race) could be creating more problems than it’s solving.”

The former Williams driver is scheduled to attend this month’s Bahrain grand prix as a television analyst, but Hill brushed aside any thoughts about his lucrative contract with the British broadcaster Sky.

“Some things are more important than contracts.”

He also expressed misgivings about a recent media briefing in London, in which Bernie Ecclestone and team bosses stood with the Bahrain organisers and insisted the race is going ahead despite the continuing controversy.

Damon said that event was “troubling insofar as it tried to represent the rioting in Bahrain as the result of bad press reporting and as a ‘youth’ issue.

“I hope the FIA are considering the implications of this fully and that events in Bahrain are not seen as they are often sold, as a bunch of yobs throwing molotov cocktails, because that’s a gross simplification.”

Writing in O Estado de S.Paulo newspaper, Brazilian correspondent Livio Oricchio admitted he thinks it would be “almost reckless” for F1 to travel to Bahrain this month.

“At Sepang,” he wrote, “many team members were very concerned. They said their insurance companies had expressed concern about going to an Arab country in a belligerent state.

“Personally, I don’t think we will be attacked, but it is the goal of the protesters to do anything so that the grand prix is not run.

“The Arab Spring is very much alive in this small country in the Persian Gulf,” he admitted.

And the Times of London’s Kevin Eason wrote on Twitter: “I have been thinking F1 should give Bahrain a chance but I am not convinced now that safety can be guaranteed.”

The FIA appears to have waded back into the ‘F-duct’ debate, indicating that the Mercedes-style solution is fully legal.

We reported on Monday that the saga looked set to continue into China next weekend, with some teams – notably Red Bull and Lotus – questioning the legality of the aerodynamic innovation.

It had emerged that Lotus technical director James Allison has come up with another argument against the technology that will be posed to the FIA’s Charlie Whiting ahead of scrutineering in Shanghai next week.

Christian Horner insists Red Bull and Lotus’ concerns are shared by others.

“Believe me it’s not just Red Bull, I think there’s half the paddock that’s been looking at this,” he told British television Sky Sport’s The F1 Show.

The Red Bull team boss revealed that Whiting left Malaysia wanting “to have a think about it”.

So, the latest development is the re-release via the FIA website of an “edited version” of the technical briefing that Whiting gave to reporters in Australia last month.

It is believed the complaining teams’ main objection to the Mercedes system is that it arguably uses ‘driver movement’ – the pressing of the DRS button – to be activated.

Under the heading “Pressing the DRS button and the issue of ‘driver movement’”, the media briefing quotes Whiting as stating simply: “This is specifically allowed (in the rules).”

Mercedes’ Ross Brawn is quoted by the BBC: “We call it the DRS, because that’s all it is. The purpose of the DRS is to improve overtaking and that’s what we’re trying to do.”

Whiting’s stance in China, however, may not be the end of it.

“Then the teams are faced with alternatives,” Horner explained. “Either accept it and get on it and maybe look at your own solution if that fits your car.

“You’ve got the opportunity to protest if we were to feel – or any other team were to feel – that we didn’t agree with Charlie’s interpretation,” he added.

Now less than three weeks before the island kingdom is scheduled to host its return to formula one, bitter protests and violence have once again erupted in Bahrain.

Witnesses claim a 22-year-old man who was filming the firing of tear gas on protesters was shot and killed by state-supporting militia on Friday.

The death – reportedly the first since last year’s troubles forced the cancellation of the 2011 race and test – intensified the clashes and calls for the forthcoming grand prix to be axed.

The government has denied it is responsible for the death.

“The ministry of interior will do all it can to find the criminal and bring him to justice,” a spokesman is quoted as saying by the Times of London.

The ministry also confirmed that Nabeel Rajab, the president of the Bahrain Centre for Human Rights, has been arrested.

He had said last week: “We are going to use the opportunities that a lot of journalists are there (for the grand prix) and we are going to protest everywhere.”

The protests, however, continued.

“We (object to) holding a sports race that belittles the sacrifices of our children and ignores our suffering and wounds,” said a video statement posted on the internet by a protester.

“Do not tarnish the reputation of the respected auto sport with the blood of Bahrain victims.”

And on Twitter, the hashtags #BloodyF1 and #noF1 are being used to protest against the race and link to graphic photos and videos purporting to depict government violence.

The 2012 ‘F-duct’ controversy looks set to keep running for now.

“It’s not over yet,” confirmed Red Bull advisor Dr Helmut Marko to Germany’s Auto Bild.

In Australia and Malaysia, the threat of results protests hung over the opening races of 2012, due to some teams – chiefly Red Bull and Lotus – questioning the legality of the aerodynamic innovation on Mercedes’ 2012 car.

Until now, the FIA has declared that the system – working in unison with the driver-operated DRS – is fully legal.

But it has emerged that Lotus technical director James Allison has come up with another argument against the technology that will be posed to the FIA’s Charlie Whiting ahead of scrutineering for next weekend’s Chinese grand prix.

It is believed that while Ferrari is on Red Bull and Lotus’ side at present, Mercedes-powered McLaren is currently staying out of the debate altogether.
