Williams’ 2008 contenders on Monday did not encounter a repeat of the front wing mounting problems that marred the British team’s running in Barcelona a week ago.
Before most other formula one teams commence running at the southern Spanish circuit at Jerez on Tuesday, Oxfordshire based Williams – with two FW30s in action – and Red Bull began the test on Monday.
In a team statement, Toyota-powered Williams said Nico Rosberg and Kazuki Nakajima had commenced the four-day programme successfully.
“Last week’s issues with the front wing mounting have been resolved and both drivers completed a list of development items,” the statement read.
Technical director Sam Michael added: “After signing off the revision to the front wing mounting system, we proceeded to work on mechanical set-up and long runs for reliability.”
