F1 2010 newcomer Virgin Racing brought its debut test with the VR-01 to a successful conclusion on Saturday at Jerez.

After only completing a handful of laps on the previous three days, Lucas di Grassi managed 63 tours on the final day, his best lap 1 minute 22.912 seconds, which left him ninth on the timesheets.

"After three days of very little running, in the space of one day we have completed lots of mileage in the dry and we were able to work through lots of important items on our programme," di Grassi noted. "The car was behaving much better after the work we did since yesterday and I think what we have achieved today is a very good start for our team.

"I would like to thank the guys for working some unbelievable hours this week. The way they have come together is fantastic and generally I am very happy with where we are."

Virgin Racing's technical director Nick Wirth and team boss, John Booth meanwhile were both relieved that the squad could finally get in some decent mileage.

"It is very pleasing to end our first test on such a positive note, having finally achieved some solid running in dry conditions," said Wirth. "We have remained focused on the job list in hand and given that we have been working with a representative fuel load to evaluate various set-ups, our lap time and rate of progress is encouraging at this very early stage."

"This is a great reward for the team," Booth added. "They have all worked so hard over the past few days to achieve such positive running on our final day here. Everyone is extremely buoyant and looking forward to being back here in Jerez next week."
