Mclaren MCL40

[michl420]

I haven’t followed the tv pictures at all really this test.
The McLaren looks low at the front. Front wing end plates touching the ground on roll, the front of the floor skimming the tarmac- a trait from the MCL39.

Have they had the car this low all test or have they been gradually lowering it as
they go?

They where always low thought the test. But I would also say the car is relativly soft on the front.

Ok. Yea I agree with the soft front too hence the rolling from side to side

That outlet is massive. Largest opening that they have run in the last 3 years.

Wasn't on the car in the afternoon today. Maybe it's for the morning session.

I'm sure it's just a test item. Interesting as even in Mexico last year they didn't have something that big.

For anyone who doesn't speak Italian...

"McLaren has brought a very open bonnet vent, a quite noticeable difference compared to the version seen in the last few days."

Different angles though. It looks a lot more open because the angle is lower.

It is a lot more open
look at the gap to the exhaust.

True and acually the smaller outlet pic is the lower angle. Apologies.

[De Wet]

is this a new less downwashing version ?

Does look different to me... Not 100% sure though.

I’m not sure that it is. Check out _cerber1 post on page 20 of this thread. Looks to have mini water slides in that pic too- if they are even water slides.

Thx... Looks the same.

Good morning. Some MCL40 pics after Bahrain testing.

Q: what is the benefit of the sidepods fairly sharp angle down to floor. Obviously it’s downwashing and a significant amount of floor real estate behind the end of the pod.

But it seems to me by lifting the pod (reducing the downwash angle) you’d be able to use it as a semi wing and have air being able to get to the rear virtually uninterrupted underneath it

Probably they expect the downwashing air to separate from the waterslide before it meets the floor, and close to the physical merging point of the two surfaces, the 'wrap-around' air from the bottom of the sidepod to 'merge' with the watersliding air and together rush towards the coke bottle area.

Like Aston Martin ?

Indeed like AM. It seems the MCL40 packaging would allow that concept so I’m just wondering what the reasoning for not going to that concept might be. I’m guessing airflow stability & predictability especially in yaw would be better with current concept but perhaps with a reduction of total mass flow

The picture below shows pretty well how the bodywork is trying to converge the air flowing over and around the sidepod and focus it into the volume between the rear wheel and the coke bottle, where the diffuser ramp begins. I'm pretty sure this will create a volume of high-pressure in that region, which will help contain the tire-squirt from the rear wheel, and should help to prevent front wheel wake from being sucked through that area and over the top of the diffuser.

Is there any directive (or test) that prohibits the front edges of the floor to flex downwards because these are massive areas this year on some cars?

Upturned rear control arm fairing to help with rear brake duct extraction

[AR3-GP]

The air at the sidepod edge ends up going underneath the sidepod.
