Williams is now focusing its main efforts on next year's car, with its final major upgrade package for 2010 having been given the sign-off in its wind tunnel.
After a disappointing start to the year, Williams has made good progress with its FW32 and, with its major update planned for the Singapore Grand Prix, it has high hopes of keeping that momentum up.
Technical director Sam Michael said that the new Singapore parts were now out of the wind tunnel and being readied, which means the Grove-based outfit's aero team were now focusing entirely on the 2011 challenger.
"We have one more upgrade for Singapore, and that is finished in the wind tunnel," said Michael. "All the bits are aerodynamically designed, but they have not finished going through the mechanical design and production yet.
"In terms of the design priority though, from an aero point of view we are focused on next year now."
With major rule changes for 2011 - including the banning of double diffusers and F-ducts, and the arrival of Pirelli as tyre supplier - Michael said there would be little carry over from this year's design.
"It is a completely different car - it will be a clean sheet for everybody," he said.
Williams plans to run KERS next year too, and Michael said the team was keeping its options open regarding whether it races with a battery or a flywheel system.
"We've got both options, but to be honest our priority will be a battery system," he said. "We do have capability to run a flywheel as well. "
