Williams is hoping that further adjustments to its diffuser design for this weekend's European Grand Prix in Valencia will allow it to continue its recent points-scoring run.
After a very tough start to the season, the squad has started to regain ground in recent races following a series of upgrades. Technical director Sam Michael said the main developments for Valencia were focused on the diffuser.
"We have some further upgrades to our diffuser and our target is to be in the points with both our cars," he said.
Having failed to score points in the opening five rounds, Williams took ninth-place finishes with Rubens Barrichello in both Monte Carlo and Montreal to open its account for 2011.
