Virgin Racing technical director Nick Wirth has said that he is pleased with the work that has been done this week at Jerez in Spain, the penultimate F1 group test of the year.
Although the squad has had a number of issues since beginning testing with the VR-01 last week, and lost more time on Wednesday with an 'elusive hydraulics problem', things went a lot more smoothly on day two.
Indeed Timo Glock managed to complete 72 tours in total, his best effort a 1 minute 30.476 seconds, which left him eighth on the timesheets, ahead of Force India's Vitantonio Liuzzi, McLaren's Lewis Hamilton and Lotus Racing's Heikki Kovalainen.
"After a great overnight effort from the Virgin Racing team, we managed to complete more than a race distance on Thursday, which is very satisfying after our frustrations of Wednesday," said Wirth.
"We also managed to prove out some development parts which gave results completely in line with the performance prediction from the development programme at Wirth Research.
"This is always satisfying as it gives the team and drivers a great and confidence-inspiring introduction to our development program for this car.
"We continue to work around the clock to fix issues as they arise, and we're looking forward to Lucas [di Grassi]'s comments on the car's progress tomorrow," Wirth summed-up.
