Williams resumed their Jerez tests in intermittent rain throughout the day working on Set-up work and system checks.
Rubens Barrichello topped the timesheets after completing a total of 98 laps with a best time of 1:27.415 with young Russian Petrov in the Renault 0.683s behind him.
Techincal director Sam Michael was happy with the day despite the changeable weather conditions, “Rubens finished off another wet day in Jerez having covered a lot of mileage for reliability. He also completed some systems checks and carried out a programme of pitstop practice. All the pitstops were done under wet conditions and we’re working on some refinements for tomorrow.”
Nico Hulkenburg is set to take over the driving duties behind the wheel of FW32 tomorrow.
