McLaren MCL39

[AR3-GP]

We don't know where the cars were and at what speeds/lateral/longitudinal loads and/or bumps were being put into the suspension.

Also the idea that Mclaren's "tire management and consistency" comes from "higher ride height" is not right.

[SilviuAgo]

Not the best way to see McLaren floor or a 360 of MCL39 but some nice aero details and design parts can be spotted (helped by the sun lightening) .

Interesting point here is that (without the spring/damper restraint) the suspension total compression theoretical is displayed as all the wishbones etc look intact.

The potential in "bump" capacity is in view here for latent mechanical arrangement.

I thought it was interesting for that reason exactly. It also shows how stiff these cars are. With just 3 wheels on the ground, the platform doesn't drop much if any at rolling speed.

Tks to @carpentiers_f1 we have also the cooling system of MCL39 in Mexico:



And hope not to bee off topic by displaying for comparison other solutions. Maybe this show the cooling efficiency of the McLaren package.

Ferrari:


RedBull:

Is it hotter than Singapore where the drivers wore body cooling suits? These vent holes are enormous.

Mexico City is 2200m above sea level. The air is thinner so they need more air flow for the same cooling capacity.

I didn't follow the last 2 seasons. Is Mclaren still using air to air intercoolers or did they adopt the air to water one, or else?

AFAIK, only Honda uses air-to-air IC, Mercedes and Ferrari PUs shifted to water-to-air long time back ; have no idea about Renault PU

@xavigazquez

By far, the McLaren’s vents are the smallest and, consequently, will have less drag. Based on FP2 long runs MCL39 looks impeccable, as Leclerc mentioned "from another planet".

“So we need to use our resources in the most effective and efficient way which for us for a few weeks meant that we needed to focus on 2026. We want to keep winning championships in 2026 and this [required] us to focus in this direction and make sure that we hit the track running with a very competitive car in 2026.”

He sounds confident about having a strong car next year as well
