Marussia know they can't afford to slack off during the second half of the season if they are to remain 10th in the Constructors' Championship.
Jules Bianchi and Max Chilton consistently outperformed their Caterham counterparts during the first half of the campaign to stay ahead of their rivals in the standings.
Finishing 10th in the Championship is crucial this year as the team that is 11th won't get any prize money from FOM and Marussia team principal John Booth knows it is vital that they keep the position.
"We also head into the second part of the season still holding 10th place in the Constructors' Championship and we are keenly focused on what we need to do at every turn to ensure we maintain that position," he said.
"The challenge begins again this weekend in Spa at what is a favourite destination for our team and the fans."
After the four-week summer break, the action heats up again at this weekend's Belgian Grand Prix and Marussia's MR02 will have a few upgrades.
"There we will have some new suspension parts and brakes to evaluate and, as ever, consistent progress during the course of the weekend and a two-car finish ahead of our nearest competitors are the target outcomes," Booth added.
