Marussia are hoping to make another step forward at the Chinese Grand Prix this weekend as they look to confirm their improved pace.
Team principal John Booth confirmed that they will introduce “significant” but not “comprehensive” upgrades in China, but he expects them to make a difference.
“The cars were freighted directly to China, so while we would not call the upgrades we have for this race comprehensive, [but] they are still significant,” he explained.
“We will be running some new suspension parts that we proved out in testing but delayed until we had some further race distance experience with the MR02. We also have some new front and rear brake ducts.”
Further developments will come at the Spanish Grand Prix which kicks off the European leg of the season.
“The bigger push will come for Europe, but for now it’s good to be bringing new incremental updates to the car to maintain our positive trajectory.
“The drivers have spent some time in the simulator during the break and generally they are feeling much better prepared for the next phase of the season.”
