Pastor Maldonado has said the Williams
FW33 'felt great' following the penultimate pre-season for F1 2011.
Maldonado, who won the GP2 Series last year and who will make his debut at the pinnacle of the sport this season, finished the final day on Monday at Barcelona's Circuit de Catalunya
sixth on the timesheets, his best lap a 1 minute 24.057 seconds.
Furthermore despite an issue with the KERS system, which meant the Grove-based outfit had to switch it off, the Venezuelan still managed over 100 tours - more than any other runner and more than double what he did on day three.
“We did 121 laps [in total today] so it's been a great day,” Maldonado reflected. “We tried lots of things on the car this morning and this afternoon we did a race simulation.
“The car felt great. We need to work to understand a little bit more about the balance on the longer runs but I am happy as the car is getting better each time we go out.”
Williams technical director, Sam Michael meanwhile also felt that overall it had been a good day, although he wasn't happy with how it began: “It has been another productive day but it certainly didn't start out like that! We had a problem with the KERS cooling system just before the session opened, so we had to disable KERS for the day,” he explained.
“Pastor then spent the morning doing some mapping runs for Cosworth and running some new exhaust components for aero to check temperatures for the last test aero upgrade that is coming - all of that worked okay. In the afternoon we completed a race simulation with no problems.
“Overall it has been a productive test although we still have some reliability issues to work on.
"The final winter test will now be held back at the Circuit de Catalunya, Barcelona from 8 – 11 March and we will be bringing our first race upgrade package,” he summed-up.
