Williams lost more time to KERS problems today, but despite this Rubens Barrichello still managed 99 laps in Jerez on day three of the test session.
The mileage accumulated by the Brazilian today was almost double that managed by Pastor Maldonado over the first two days – the Venezuelan yesterday fell victim to a faulty sensor in the KERS battery and a crash.
Technical director Sam Michael explained the team are still making progress despite the lack of mileage, and described the problems today. “After a couple of setup runs this morning we had a problem with the KERS onboard cooling system,” he said. “We had to stop and remove some components to ensure the car was safe, and that cost us three hours.
“In the afternoon we made good progress with the aero setup of the FW33 on long runs, with Rubens generating some good data for the wind tunnel.”
Barrichello will be back in the FW33 tomorrow for the final day of the Jerez test.
