McLaren MCL39

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

It seems like there's less flex on the MCL39's front wing, but I can't be certain if it's due to the slightly different onboard angles or not. But even when looking at the onboard videos (not static images like these) of the MCL39, the flap movement doesn't seem as dramatic on the braking zone as it was with the MCL38.

"XD what McLaren revealed in MCL39 xD I'll post it soon"

"If I don't post it, I'm sure no one will find it at least until the middle of the season XD"

Patryk (ex mclaren aero) seems to have spotted something interesting on the car, I've been combing through pictures can't seem that "thing" could be the hidden innovative element Zak has been referring to

The kick angle on the outermost step seems to have increased. If you look at the almost vertical wall inboard of that you'll see it's larger without the keel being any larger. Indicates the steeper diffuser angle there.

The side mirror arms are almost a wing themselves. The same with the Ferrari but not to the same extent. It’s pretty clear on the on boards just how much wider they are.

I wouldn’t mind having a better look at the rear suspension. From the rear it looks like they’re using one of the arms as a beam wing, but it’s hard to properly see it from other angles.

As for the innovation Zak is referring to, I’d imagine it’s either around the diffuser or front bib. Somewhere that’s hard to see but not impossible. It could be somewhere else entirely though.

I’m thinking the same regarding the rear suspension/ beam wing….

Even if the suspension isn’t being used like that, there are some very interesting/different rear suspension geometries. Everyone seems more focused on the front suspension, but I’d like to get a much better look at the rear suspension. There’s definitely something interesting going on there.

Maybe Ted was right… look at the rear wing end plate, especially from the front- that’s a shape we haven’t seen before?

Most definitely. Is the beam wing slightly wider or do the angles/distances confuse?

Looks to me like they've changed the way the rear wing uprights are interacting with the airflow around the rear tyres.

There's a bulge at the inside front of the uprights too which i don't recognise, they are quite heavily sculptured.

There are small air outlets below the rear suspension, right below the most upper/forward arm, anything significant?

They have been there since shakedown. RedBull exit almost same place. So mclaren just decided to have 3 outlets, but can then make the rear a lot slimmer

The tighter and slippier you can make your car, the more air you can get to the rear to increase downforce. It's a double win.

Hot air to energise the flow , smaller exhaust area to increase coanda effect, area inside the rear wing shaped to catch more flow and a streamlined package in front to deliver the airflow.

Looks like the rear suspension is as extreme as the front suspension in regrets of "anti dive". The forward leg of the upper wishbone looks like a pullrod from that picture.

The hot air from outlets will not be anywhere near hot enough to energise the flow, nor will it be powerful enough to produce a jet (hence coanda effect not relevant) after passing through radiators etc

They have the cooling outlet at the suspension because it's an efficient solution with high energy air aiding extraction and the losses pass in between BW and RW, not about powering up aero devices etc
