Virgin happy with progress
The aim is to up their speed, starting next week in Turkey.
There will be comprehensive changes to the car, chiefly aimed at closing the gap with nearest challengers Lotus, and Team Principal Booth is confident that their target can be achieved.
“We are probably a second and a half off where we wanted to be. It’s a massive gap but, yes, we can close it,” he says.
“We’ve got the major upgrade this week and then another one for Silverstone.
“It’s not going to be easy but it is achievable.
“We haven’t got the resources to do both at once, so we had to get the reliability right first and then up the performance. We have achieved one so now we’re aiming to improve the other.”
