Istanbul: The Williams team arrived at the Istanbul Park circuit to prepare their `old` cars after losing a race against time to build updated versions following a crash-marred showing at the Monaco Grand Prix.
Both veteran Brazilian Rubens Barrichello and German rookie Nico Hulkenberg had crashes in Monte Carlo which left both of their cars needing major repairs and new parts.
Technical boss Sam Michael said: "Nearly all of the items that needed replacing after Monaco have been done - apart from the front wings, which require more time.
"As a result of that we have had to revert back to a previous specification of the car for this race in Turkey."
Michael tried to put an upbeat spin on this setback by adding that they expected to have all-new updated cars ready for the Canadian Grand Prix in Montreal on June 13.
And he added that they hoped to have a performance boost from using upgraded Cosworth engines this weekend together with new brake ducts and other minor mechanical changes.
Barrichello`s car was damaged because of a loose manhole cover which prompted the third Safety Car period in the Monaco race after Hulkenberg crashed at high speed in the tunnel on the opening lap.
Barrichello was, at least, relieved to learn of the cause for his accident on a bleak weekend for the team that is struggling to revive old glories.
Williams are currently down in seventh in the constructors standings with eight points from six races. Once one of the `greats`, they last won the drivers and constructors titles 13 years ago - in 1997.
Barrichello said: "Returning from Monaco with a DNF for both cars was very disappointing, particularly as we now know the cause of my accident.”
"I know everyone has been working hard in the factory, so we are all looking to have a much better race in Turkey.”
"Istanbul is a favourite track of mine. It has a good layout; the corners all flow nicely into each other and that makes it a smooth lap to drive.”
"Because the circuit runs anti-clockwise, the left-handers can be quite a challenge on your neck muscles but we all do extra training to compensate for that."
