Virgin test shark fin on updated car
Virgin Racing have brought a number of updates on its only modified car, the one of Timo Glock. Due to the delays in air traffic in recent weeks, the team were unable to complete the second extended wheelbase chassis in time, which is why Lucas Di Grassi will race it for the first time at Turkey.
Glock however tried a new shark fin cover on Friday morning, but eventually opted against it for the race. Also note, as marked by the arrow, that the rear wing features an additional slot in the middle part of the wing to create additional downforce.
