Day 4 of 4 for Williams

On the last day of testing at Jerez, Alexander Wurz and Mark Webber took the track for the Williams F1 Team. Wurz continued working on reliability running for the engine and gearbox. Webber had to stop early today after a problem with his suspension.

Sam Michael, Technical Director, WilliamsF1 Team “After a wet morning, the track dried out around lunchtime. Alex continued working on reliability running for the engine and gearbox, while also fitting in some set-up work. Unfortunately Mark had to stop early as we were short on suspension spares with which to repair his car after an off. Overall, Jerez has proved to be a good test for reliability with the FW28, and we now look forward to Valencia next week and working on further set-up options and carrying out tyre testing with Bridgestone.”

Simon Corbyn, Head of F1 Race Engineering, Cosworth “Cosworth had a good week in Jerez with WilliamsF1. The latest CA2006 performance developments were successful, plus the engines ran in excess of the two race weekend life requirements with no issues. The Bahrain GP CA2006 Series 2 engine specification, which incorporates further performance and reliability updates, will track test next week in Valencia and the priority for the engine development programme will now shift to delivering the further upgrades scheduled for introduction during the 2006 season.”
