Timo Glock says Virgin Racing is making improvements with its current car after completing work on McLaren's driver simulator for ht first time.
Glock's Virgin team entered into a technical partnership with McLaren earlier this season following the end of its relationship with Nick Wirth, with the German now getting the chance to sample the McLaren simulator as part of the deal.
While not necessarily seen in the results on track, Glock said that the simulator work had shown the improvements being made by the team in recent months.
"My feeling is that we have definitely improved," he told Auto Motor und Sport
. "It can't be easily seen because Lotus have also brought improvements which equalised our step.
"But the data has confirmed what I have felt in the car."
Since the split with Wirth, Virgin take on Pat Symonds to oversee development of its 2012 car, with the McLaren simulator again being seen as an integral part of the work on the new machine alongside a new wind-tunnel programme.
