Preparing for the first race of the season
Williams Cosworth completed the fourth and final day of testing yesterday at Circuit de Catalunya with Nico Rosberg and Alex Wurz setting the sixth and tenth best times respectively.
It was a mixed week for the team but the final two days of running did allow Wurz to complete races distances with the FW28 package.
Rosberg has now completed 6356km of running since November 28th with Webber just under 5,000km and Wurz 500 less.

“Today Nico and Alex finished testing in the cold conditions in Barcelona. Nico worked on tyre testing for Bridgestone, focusing on their different compounds. Meanwhile, Alex concentrated on long runs to investigate various mechanical set-ups and brake cooling. We tested some new aerodynamic parts for the FW28 this week and confirmed they are all working as expected.”

Simon Corbyn, Cosworth Head of F1 Race Engineering
“Cosworth completed this week’s Barcelona test in reasonable shape. The first day was difficult as we had to stop running Mark’s primary Series 2 test engine when it developed a leak which couldn’t be fixed trackside. In addition, Nico suffered an engine failure, although this was at high mileage and was an earlier spec engine."

"Fortunately, the remainder of the test was rather less eventful as Alex successfully exceeded the two race weekend target mileage on his Series 2 engine, plus we were able to complete valuable engine calibration work in preparation for Bahrain.”
