The drama stepped up a notch even after the chequered flag in Barcelona.

A couple of hours after Williams’ first win since 2004, something exploded in the British team’s garage, triggering a major fire.

Team members and fire crews battled the blaze as paddock regulars scrambled away from the heavy smoke and police arrived on the scene.

The Telegraph’s Tom Cary said on Twitter there are “multiple injuries”.

It is believed Williams, Force India and Caterham staff – some of whom bravely fought the fire – are being treated in the medical centre, some for smoke inhalation.

An emergency helicopter will ferry others to hospital.

“Couple of our guys got injuries, burns and maybe one broken wrist, no news on Williams guys I hope they’re ok,” wrote Caterham’s Heikki Kovalainen on Twitter.

Rumours indicated the fire could have been caused by a KERS explosion, or possibly fuel, as a burned fuel rig was pulled from the gutted garage.

Peter Sauber is sporting some bumps and bruises this weekend following a fall in Melbourne.
Switzerland’s Blick newspaper reports that the 68-year-old team owner and boss fell at the paddock entrance at Albert Park last Sunday, taking the brunt of the impact with his elbow and wrist.

“It still hurts,” he admitted. “All I could think of at the time was to protect my face.”

Sauber was treated by McLaren doctor Aki Hintsa, who said Sauber was lucky not to have injured himself more badly.

Kimi Raikkonen has revealed he actually broke his wrist just before Christmas.
The media made much of the returning Lotus driver’s apparently hurt arm, but he insisted at the time it was “the smallest and slowest crash I’ve ever had”.

But during his appearance on the popular British motoring programme Top Gear last week, 32-year-old Raikkonen confessed to having been more seriously injured.

He showed anchor Jeremy Clarkson a big scar on his left wrist, admitting: “I hurt it a little bit, but I had a good doctor to fix it.”

“That’s a big scar!” Clarkson exclaimed. “Did you break it (your arm)?” he enquired.

Raikkonen smiled: “A little bit.”

Force India has become the latest team to incorporate a F-duct style concept in its 2010 formula one car.

After McLaren pioneered the rear downforce-stalling innovation this year, teams including Ferrari, Mercedes, Williams and Sauber have followed suit.

The already-dominant Red Bull is also expected to debut an F-duct this weekend in Turkey, as will Force India.

The Silverstone based team said on Thursday that the version for the VJM03 car is called a switchable rear wing or SRW.

“Should be a good improvement,” Force India said on its official Twitter.

Vitantonio Liuzzi told reporters at Istanbul Park that he and teammate Adrian Sutil will activate the flow of air through the engine cover and rear wing slot by covering a hole in the cockpit with their wrist.

“The target is to get into Q3 and then score points,” he said earlier this week.

“We deserved to have a double points finish earlier than Monaco, but for some reasons it didn’t happen, so we need to continue to put both cars the top 10 if we want to catch Renault.”

Ferrari, on the other hand, has modified its initial Barcelona-spec F-duct for Turkey so that the drivers block the inlet with their knee rather than their hand.

It is believed Felipe Massa is particularly happy with the change, given that in Spain he had to move his hand further than Fernando Alonso to block the inlet due to the position of his steering wheel.

The Catalan pilot, Dani Pedrosa (Honda) assured he had “good sensations” in his left wrist, after the screw was removed last December.

“The sensations I’ve had in my left wrist have been good and that’s something positive.  Overall, today I have taken everything easy, because we have plenty of time to continue with the enhancements, starting from tomorrow,” he declared after the first tests in Sepang.

Pedrosa, lapped 51 times and marked eight best in the day.  He pointed out that due to the time he has not ridden a motorcycle, it has been difficult for him to “adapt to the speed and find his rhythm,” thing he considered “normal”.

“We were not aiming to get great times per lap nor obtain great performance.  We have spent part of the day working in the ‘Ohlins’ suspensions, because they’re an important change from last season,” Pedrosa added.
