Virgin Racing technical director says he is hopeful that the team's 'digital development process' will lead to an upturn in performance this weekend in Monaco.

Having debuted its revised VR-01 in Barcelona last weekend, the team will introduce a series of modifications to the car of Timo Glock for the biggest race of the F1 season as it seeks to close the gap to rivals Lotus and then make progress toward the rest of the F1 field.

For the second successive race, the team will continue to run two different cars, with Lucas di Grassi due to get his hands on the revised Virgin chassis at the Turkish Grand Prix at the end of the month.

"Monaco represents an interesting technical challenge, which the Virgin Racing drivers and many of the engineering team are quite familiar with," Wirth said. "A car with stable aerodynamic characteristics, high downforce coupled with good ride is typically fast here. As usual, we've done our homework back on the Wirth Research simulators in preparation for this fantastic event, and for the last time we will be running two different cars until Lucas gets his new VR-01 in Istanbul.

"We anticipated, and observed, quite a difference in the aero characteristics of the two different cars in Barcelona and this will be amplified again as we bring some more aero parts to Monaco, some arriving so late that they will only be running from Saturday. As we gain more experience with our unique digital development process, it looks like our forthcoming developments will start to lift the cars' performance both here and at future events."
