Timo Glock has again expressed his frustration at the lack of progress from the Marussia Virgin team since last season, lamenting how much of gap has developed between it and fellow 2010 newcomer Team Lotus.

Although the Hingham team has yet to open its points account, and has struggled with reliability in the opening three rounds of 2011, Glock and rookie team-mate Jerome d'Ambrosio have rarely been able to take the fight to the green-and-yellow machines as he did last year. Not classified in the opening round in Australia, the German has managed on 16th and 21st-place finishes, while d'Ambrosio's best of 14th, in Melbourne, still had Marussia Virgin behind the sole remaining T128.

"It's not been a perfect start to the year for us, but we just have to get on with it and make the best out of it," sighed Glock, who apparently returned for a second year at Virgin despite interest from Renault ahead of the 2011 campaign, "At the moment, we are too far away from Lotus. I just hope we manage to be closer here and have to watch out (that) we stay where we are at the moment."

Like most of its rivals, Marussia Virgin has taken the opportunity of the three-week break between the races in China and Turkey to work on the first update of the season, and Glock admits that its success could be crucial to the team's season.

"I am not happy with the car at the moment, that's the main point," he stressed, "I think, aerodynamically, we are not where we should be.

"However, we have a big update here and we think we have a good step forward, but you never know how it's going to work out and you never know how it's going to be on track. The numbers are looking good and we have to see if that turns it around on the track. The simulator and all that stuff went okay in the last week and I think the parts are not looking that bad but, as I said, it counts on track and we have to see what we can do here."
