McLaren has a list of improvements they are planning for the new MCL35M in order to iron out the issues that it's predecessor the MCL35 suffered in 2020.
With the Woking-based outfit pairing up with Mercedes for the first time in seven years, the team will attempt to rectify an issue with the car in low-speed corners and in various conditions.
Technical director James Kay talked about what worked on the old car and what the team could improve upon for 2021 when talking with Motorsport.com.
"I think our strengths have been typically the high-speed corners, certainly from the beginning of the season, we were very competitive in the medium and higher speed corners."
"Straight-line braking has been another strength of ours as well, which benefited us on some tracks – like Austria for example.
"I think in terms of weaknesses, we still need to improve ourselves a bit at low speed. It's not quite as weak as it was [in 2019], and that was one of the big pushes to try and improve that low speed, balance and consistency that we had in certain types of low-speed corners."
"Then, in some conditions, the car doesn't perform quite as well as we'd like it to - and that's in some weather conditions or some grip conditions, which we can kind of see in the data."
"We need to understand that actually, but it's not one of those overnight fixes. So that's what we're really targeting. I think if we can iron some of that out, we'll have a more consistent car from one race to the next."
Key, however, said the issues that they suffered weren't confined to McLaren alone as he proclaimed that the team would work out a way to iron out the issue.
"It has been a bit of an issue for us, we think we've pinned it down to one thing, which is just a characteristic of the car that we need to iron out."
"But with all these things, there's no silver bullet – you just have to work on it. But there is an element of probably being a bit more affected by it than others, positively as well as negatively, depending on the direction of the wind."
"Every car, of course, suffers from this. Our drivers have said they've seen cars ahead locking up and having troubles as well when it is windy, so I think it affects everyone."
"But possibly on occasion, when it's been in the wrong direction or affected a certain corner a certain way, it has had the worst effect on us."
