Chilton expects 'hard' season
Britain's Max Chilton expects he and the equally inexperienced Luiz Razia to experience some hard times with Marussia in 2013.
Chilton's team-mate for the coming Formula One campaign was confirmed last week as Razia, with both men graduates from the GP2 Series.
Marussia have made no secret of the fact they were forced to bring in Brazilian Razia and part company with the experienced Timo Glock for financial reasons.
It means the Banbury-based team have no driver feedback on the differences between last year's car and their new challenger.
Chilton expected Glock to be his team-mate when he signed for Marussia, and he admitted the German's exit is likely to create occasional difficulties.
"It is not ideal, and we will sometimes have a hard time," he said.
"I had been looking forward to being Timo's team-mate because he is very experienced.
"But I'm sure we will have no problems as we wouldn't be in F1 if we weren't capable."
Glock, who has moved on to the German touring car series, DTM, has expressed his own concerns about the problems likely to be faced by Chilton and Razia.
Speaking to Autosport, Glock said: "It's definitely not going to be easy for them, especially in testing, where you need to be able to make the right decisions in pinpointing the weaknesses of the car.
"That's something that only comes from experience. There's a lot of pressure on Luiz and Max to get up to speed with the car quickly.
"That's the critical part: knowing that perhaps the simulation you have brought to a track isn't quite accurate and being able to make a forward step from there."
