McLaren racing director Andrea Stella has confirmed the team will continue to bring updates to the MCL35M into the second half of the season.
McLaren introduced a number of bargeboard upgrades to the Hungaroring and in the team's fight for third with Ferrari, it will continue to bring a number of changes after the summer break.
Lando Norris retired and Daniel Ricciardo was hampered by the lap one chaos at the Hungaroring and Carlos Sainz's podium, which is subject to Aston Martin's appeal against Sebastian Vettel's disqualification, put Ferrari level with McLaren on points.
"They will not be the last upgrades of the season," said Stella.
"Simply because when you release upgrades then it takes some time to produce them and [for them] to land trackside. So there will be a few more.
“And also, in Formula 1 you always keep acquiring some information once you test the parts trackside because you never get the perfect correlation with the development tools.
"So once you test some upgrades trackside, you normally get information for further finetuning which doesn’t necessarily require to go past the wind tunnel.
“You simply can adapt sometimes based on CFD for example associated with what you learnt by testing parts trackside."
Team principal Andreas Seidl commented at the Spanish Grand Prix that the team wasn't far away from switching its focus entirely to its 2022 project although some "low hanging fruit" remained with regard to smaller upgrades.
Echoing Seidl's comments, Stella continued: “So this upgrade in Hungary is not the last one. There will be some more tweaks that will be tested in future races.
"Nothing major but some parts will come.”
