JOHN Booth has told The Star he is uncertain over what size Marussia Virgin Racing’s aerodynamic upgrade will be at the British Grand Prix next month.
Rotherham-born Booth, the team principal and sporting director of Virgin, had said the target was to unveil a new car performance package at Silverstone.
But now it has emerged Virgin, who have sacrificed pace for reliability in 2011, are behind schedule with their latest modifications.
Booth, looking to close the gap on rivals Team Lotus, said: “We are a little bit sketchy on where we are going to be at Silverstone. It is difficult for us to see how big an upgrade it is going to be at the moment. It is all time dependant.”
At the start of their second year in Formula One, Virgin’s goal was to regularly reach the second session of qualifying on Saturday’s. But, due to a shortage of speed, the Dinnington-based outfit continue to languish at the back of the grid and bow out in the early stages of qualifying.
After a bright start in Valencia at the weekend, Virgin driver Timo Glock fell to 21st on lap four and that is where he finished at the European GP, more than 16 seconds behind Team Lotuses Jarno Trulli while team-mate Jerome d’Ambrosio crossed the chequered flag in 22nd place.
