Sporting director Graeme Lowdon says Timo Glock's twelfth place finish in Singapore was just reward for the Marussia team and an indication that the Manor-run team is making steps in the right direction.
Glock's result was the best yet for the team since it joined F1 at the start of the 2010 season and means it has now moved ahead of Caterham in the points race.
With six races to go, Marussia is now on course to earn tenth spot and the financial rewards that entails, with Lowdon saying the result was a huge boost for everyone involved.
"It was great to get a result like that,” he told the Press Association
. "Above all it was a reward for all the hard work and effort that has gone in by everyone back at Banbury who have done a great job putting improvements on the car.
"What we're finding now is we are competitive with the cars around us, and yet they're running with KERS and we're not, so that bodes well for the rest of the season.
"For everyone, we all know how difficult this game is, and often the work of the guys at the back of the grid is not often seen, but it's as intense as if you're fighting for the championship. We obviously want to finish as high as we can, and that means top ten, which will mean a massive difference to us in terms of financial reward, so it is really, really important.
"It is also important we focus on the next races and we hang on to what we have."
Marussia, and its fellow newcomers, now shares the record for the most starts in F1 competition without scoring a point but Lowdon said he felt the team was getting closer and was pleased with the progress being made on track.
"We're knocking on the door now," he said. "We're still working harder on development and we're very hopeful we will continue to improve in the next few races.
"None of the new teams are there on straight pace yet, we're still relying on something happening in front, but the gap is closing. So we're really pleased with the progress being made."
