Red Bull Racing's Mark Webber has said he is not worried by the engine failure that stopped him at the end of second free practice today in Turkey.
Webber, who was eighth in FP1 and second in FP2 - just 0.098 seconds off pace setter, Jenson Button, was forced to stop a turn 2 with only a few minutes to go when his Renault power-plant cried enough.
Despite ending the day with smoke coming from the back of his RB6 though, he remained upbeat and added that the unit was an old one anyway.
“The engine went at the end of P2, but it was a high mileage engine, so we were expecting it to be on the edge,” Webber explained. “There's no hand brake on a F1 car so when I stopped I was trying to tell them to put something behind the wheel to stop the car rolling back. A frustrating thing to explain from within the car!”
Red Bull Racing meanwhile was trying out their version of McLaren's F-duct device for the first time today, and Webber noted that the early signs are pretty promising.
“We need to analyse the new F-duct system tonight, we know it's not the most straightforward of systems,” he continued.
“The guys have done a phenomenal job to get it to this point though and we're happy with how it went today but, whether we race it or not, we don't know yet,” he added.
Sebastian Vettel meanwhile was also pleased with how the F-duct performed, and he finished proceedings fifth in first practice and third in second practice.
“It was a reasonable day – and quite tough as we introduced the F-duct. We still need to do some fine tuning, but it looks good,” Vettel commented. “I think McLaren looks very competitive here, their system seems to be working well and they seem quite a bit quicker than everyone else on the straights.
“You can make up time in the corners, but there are quite a few straights joining them. We'll see if we keep our system on. It feels more natural now with the new chassis, it was good to change it and overall I was happy with the balance of the car.”
