Max Chilton believes there are plenty more to come from Marussia after his P13 in Australia.
The 22-year-old started the season opener in 17th place and he didn't make the best of starts as his car stalled on the formation lap, but the team managed to get the MR03 running again and sent him on his way.
Despite struggling during pre-season, Chilton went on to complete the race and took the chequered flag in 14th place following a number of retirements, but he moved up one spot after Daniel Ricciardo was excluded from the results.
For Chilton there are plenty of positives to take out of the race and he feels Marussia can still take several strides forward.
"Obviously it wasn't the perfect race, far from it, but it was good," he told Press Association Sport. "At the start it was worrying. I went through my normal procedure on the grid, but the whole car went dead and it was stuck in gear.
"The hardest thing was trying to get it off the grid, but we managed to start it in the garage. We then started in the pit lane and from there we didn't have one issue the whole race, which is a good sign reliability-wise.
"If you had said to me when we were testing in Bahrain I would finish, and in this position, then I would definitely have taken it. We've definitely more to come from the car, but it still feels like we are testing it, to be honest.
"That was my first proper race experience of this year's car, and Jules and I are still learning stuff. There are big gains to be made, so exciting times ahead."
