The telemetry and data literally back this up.
He isn’t saying McLaren are sabotaging him.
He has an actual car issue that he says the team need to work on and get on top of.
The way 81s jumped straight on him and automatically said he was lying and making stuff up with no proof or evidence of the contrary.
lando on mclaren's straightline speed deficit and why his car has it worse than oscar's:
"it is an area we just need to look at because we just look a step worse than mercedes in everything straightline related, so it is tough, especially with my car, which is worse than [piastri's]. so it is making our life very painful.
there are multiple issues, and there are more on my car for some reason than the other car, so we have to understand why. we need to take a big step in that direction if you want to be competitive on any straightline speed track for the rest of the season.
i'm basically having to push more than oscar to try and make up for the [lack of] straightline speed, and mercedes have a very efficient car; they have done for years"
