Renault: Heidfeld salvages points from poor weekend

2011 British GP team reviewPosted on | Author Keith Collantine

Renault suffered their worst qualifying performance of the year, partly due to the change in the rules on exhaust-blown diffusers.

However they also had difficulty getting the wet and intermediate tyres up to temperature. They also found their new rear wing design wasn’t working well in wet weather conditions and reverted to an earlier version.

Nick Heidfeld

From 16th on the grid Heidfeld made steady progress, passing Kamui Kobayashi for 11th on lap 19.

His two-stop strategy elevated to eighth place by the end, but Heidfeld said managing the tyre wear was difficult:

“It was an interesting race for me as I had to look after my tyres and at the same time I had to attack and also defend at different times, particularly with Michael [Schumacher] and Adrian [Sutil].

“Finding the balance between attacking, fighting and not killing the tyres was not only very satisfying, but it also worked out well for us with four valuable points.”

Vitaly Petrov

Petrov may have been down in 14th but in a close qualifying session he was only 0.15s from the top ten.

But he went backwards in the slippery conditions at the start, being passed by both the Toro Rossos and falling to 17th.

He made better progress after switching to slick tyres, and ran a long middle stint during which he picked up for places.

But he finished out of the points in 12th, the last driver on the lead lap.

Afterwards a frustrated Petrov criticised the positioning of the DRS zone: “I lost some positions and was unable to protect myself because the traction was very poor and other cars were able to pass me like I was not there.

“The DRS section was not helpful at all; they should change its position on the track because it just wasn?t possible for me to overtake here at Silverstone. I was very close to Adrian but just could not get past, so that was a big frustration.

“Even on the back straight, there was not enough KERS to overtake so it would be better to put DRS there.”
