Rosberg fastest again at Barcelona

Rosberg, at the wheel of the Toyota-powered FW29, finished ahead of teammate Alex Wurz as he focused on mapping and set-up work. Wurz spent the day doing long runs and completed a race distance.

Meanwhile, the Spyker team worked with their two racing drivers Christijan Albers and Adrian Sutil, the Dutchman's day being hindered by a hydraulic leak that cut his running short.

"We had a reasonably productive day, working on the basic set-up and building up speed over a race distance," said chief technical officer Mike Gascoyne. "Adrian had no issues during the day, however Christijan's car developed a hydraulic leak that cut his race run short.

"It's not a major issue though and we should be back out tomorrow. This morning was a bit cooler and we had some problems trying to get the tyres to work, but we've got a handle on how to better the situation."
