Marussia team principal John Booth says that his team will be bringing major upgrades once the sport returns to Europe.
Marussia has recorded a best finish of thirteenth this season with Jules Bianchi narrowly missing out on making Q2 in Malaysia.
Booth says that while the MR02 will feature updates in China this weekend, bigger upgrades won't be fitted until the European stint of the season
"While we would not call the upgrades we have for this race comprehensive, they are still significant," he said.
"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. 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."
Bianchi completed eight laps for Force India during practice at the Shanghai International Circuit last year and adds that he is pleased with the start to his season.
"For me also, I was able to reflect on what has been a bit of a whirlwind, but a very positive start to my first season of F1 nonetheless. I am quite happy with the progress so far. It’s all about maintaining the momentum now, so it is good to know that we head into the next race with some new developments which should carry us forward again."
