KERS has provided Williams with a huge headache throughout the pre-season tests, and problems struck again this morning as the team began their final pre-season test in Barcelona.
Pastor Maldonado was limited to a mere 29 laps this after much of the morning was lost to the KERS fault.
“It hasn't been a good day as we didn't complete our planned programme,” said the Venezuelan. “We unfortunately didn't get enough running in to make too much progress.”
Technical director Sam Michael explained that the team opted to disable the system in the afternoon, just so they could get some running in before the end of the day. “It has not been a productive day for us after we had a KERS fault first thing this morning,” he said. “We removed the system and were able to get out for some limited running late afternoon.”
Rubens Barrichello will be in the FW33 tomorrow for Williams’ second day of this test session.
