Mattia Binotto recently announced that Ferrari will be introducing a power unit upgrade before the end of the 2021 F1 season, however Charles Leclerc didn't shed any light on when that update will take place.
Ferrari boss Binotto stated that the update will be wide in scope, taking in most of the components and ancillaries of the engine, as the team prepare for the engine freeze that will be introduced in 2022.
Asked when Ferrari plan on introducing the upgrade, Leclerc kept his cards close to his chest.
"No, I can't [say]," Leclerc told RacingNews365.com and other members of the media. "I know there's an upgrade and it will be under the hybrid part of the engine.
"When we'll bring it, we don't know yet."
The 2022 F1 season will see a major overhaul of the technical regulations, and Leclerc is hopeful the changes will help Ferrari become a title contender after falling down the grid the last few years.
"It is definitely a good opportunity for us, as it is for everyone on the grid as we are all starting back from zero," Leclerc added. "I feel we are doing a good job as a team, and I trust the job that we are doing.
"Let's see how it goes, but it is definitely an opportunity. I hope we will take it in the right way and we'll be able to fight for the title next year along with other teams."
As for this weekend in Belgium, Leclerc believes Ferrari will struggle, though he's holding out hope that won't be the case.
"I think this particular track is, on paper, quite a difficult one for us," Leclerc stated. "On the other hand, we've had some good surprises this year already.
"So hopefully we'll have another good one this weekend, and we'll be more competitive than what we thought coming here."
