Kubica: We need to improve balance

5 November 2010

Renault's Robert Kubica remains 'cautious' tonight, despite a strong showing Friday in practice for this Sunday's F1 2010 Brazilian Grand Prix.

Kubica, who finished the day sixth overall on a 1 minute 12.882 seconds, sandwiched between Felipe Massa's Ferrari in P5 and Jenson Button's McLaren in P6, revealed that the team will need to do a lot of work prior to final practice tomorrow as the set-up of the car is a bit variable.

“Our position looked pretty good in both sessions today but we know from experience that Friday can be misleading, so we need to be cautious,” Kubica confirmed.

“The main target overnight will be to improve the balance of the car because it was not ideal today – I was struggling with inconsistency and low grip. None of the changes we made really allowed us to make a big step forward, so we need to work hard this evening to make progress. Although the circuit was quite slippery early on, the grip levels picked up quite quickly, so we had a consistent basis for our testing.”

Renault chief race engineer, Alan Permane was also a bit disappointed: “It was actually a bit of a frustrating day, and we struggled to find a car balance that Robert was happy with. He suffered from inconsistency, probably owing to the low-grip surface here, and we will work tonight to improve that and make the car easier to drive,” he added.

Vitaly Petrov meanwhile was 15th in both sessions and he ended the day about a second slower in the sister car. He also suffered another off and crashed out near the end of FP1.

“We lost quite a lot of time this morning after my accident, and that obviously had a knock-on effect this afternoon as well,” said the Russian, who has yet to sign a new deal for 2011.

“It's been a difficult day for me, but I have enjoyed driving this circuit, which gives the driver quite a lot of challenges. We need to work hard tonight to ensure that we can make up for the problems we had today.”

Permane chipped in: “Vitaly endured a very tricky day. A problem with the rear wing caused him to crash during this morning's session, and the mechanics did a good job to get him out in good time in the second session. But he was always playing catch-up after that, and never really got comfortable with the car balance.

“We've got a lot of work to do tonight now, to improve both cars and get to where we want to be. What's more, the weather forecast indicates that we'll probably have rain all day tomorrow. That will be an added challenge – but, as always, could also give us an opportunity."
