Williams brings further upgrades

Rubens Barrichello, Williams, Istanbul 2011Williams will try out a new exhaust-blown diffuser and intends to run its upgraded rear wing on both cars in this weekend's Spanish Grand Prix as it continues its push to get back on the pace.

The team - which has yet to score a point in 2011 - only raced a small proportion of its new parts in Turkey after issues with airflow separation on the rear wing, and because Pastor Maldonado damaged his copy of the latest front wing in a practice crash.

Technical director Sam Michael said the diffuser would be evaluated at Catalunya and the wings would be on both cars.

"Since the Turkish Grand Prix, we have been working on our new rear wings that we ran in practice at Istanbul Park and we will have them on both cars again in Barcelona," he said. "In addition to that we'll have new exhaust blown diffusers to test."

Rubens Barrichello is optimistic that the team's work will pay off this weekend.

"I hope that we as a team can make a good jump forward in performance with our upgrades in Barcelona," he said. "I remain positive that we will."
