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.

There was a time not long ago that our little papaya car looked under developed. Just look at that suspension setup, it's like sculpture.

A simple curiosity of the 39 is also where the water slide starts on the side pod. It starts very much behind the cockpit compared to Ferrari and other teams. Some cars have none, like the Mercedes, others have it, but it starts closer to the front.
The brakes and suspension and flex wing would have you believe there is no devil in the details of the body.
For Sure!!

McLaren used again a big tank, nearly 3-4
liters capacity filled with dry ice to be able
cool the cockpit for prologued time. In fact
the way MCL39 runs wears the skid block
further forward than most of the cars, right
under the cockpit area, increasing the heath
under the driver.

They introduced that design in Miami 24 to reduce drag.

And soooo ...... 3 to 4 litres of dry ice capacity, unidentified "silicone" hose within rear brake assembly !

2+2=5 I'm surprised there's not any conspiracy theory floating around, anywhere.

I don't believe it's a system, but nobody talking about it at least just seems odd.

McLaren understand the tyres better than the other teams. They take more than just 1 lap to bring the tyres up to working temperature. I noticed this listening to Piastri and Lando's radio.
The car is probably very much biased to qualifying at the front, then managing the pace from there to bring in the tyres carefully, as counter intuitive as that sounds giving MCL39's strong tyre management and race pace.

It's what Merc did, built a car that wasn't great in dirty air, and was designed to get in front and stay in front.

Worth mentioning too that the Mclaren did 2 fast laps on the same times in Q3 recently, setting the fastest times on the second having done a cooldown lap in the middle. Quite astounding.

i never heard of a team adding weight just to cool the driver....

btw If my memory serves me correctly, FIA said that cooling the brakes with a gas it's not against the rules

There is! An Italian on its Youtube Channel says:"Are they trying to pull our leg? 3 to 4 kg of extra weight so far away from the CoG to cool the driver? That serves a different purpose!" According to him, these 3 kg of dry ice are supposed to cool the tires... The theory that dry ice, which changes its state to gas at 5 degrees, is used to cool the tires says it all.

Waiting for a rival to brake check the McLarens in Canada because we are one nose change away from proving this thesis is another fantasy herring :roll:

This theory is so ridiculous that I don't think there's anything to worry about in this regard. A material weighing 3 to 4 kg that turns into a gaseous state at 5 degrees Celsius is supposed to keep four tires and brakes within the window for an entire race? That alone is completely absurd. The next question is: how is the gas supposed to get there to cool it? There are no pipes, units, or ducts that could transport it there. Therefore, this theory is so absurd in every respect that there is no danger of anyone with any sense taking it seriously.

this is pure speculation

let's assume they are cooling only rear wheels

it' 3-4 litres, dry ice density is about 1,5 so it's 4,5-6kg

6 kg of dry ice generates 3300 litres of CO2.

for a 90 minutes race it's 18,3 litres/minute (or 0,3 l/sec) of 5C CO2 for each wheel

again, this is pure speculation but nobody add 4,5-6kg of weight on a F1 car just too cool the drivers (and the mandatory cooling equipment by FIA is totally different)

If they’re happy with the balance (very loaded front), they can remove the front wing ballast and put that weight somewhere else where it can benefit drivers as well.

It doesn’t have to be so complicated.

EDIT:
Although as I come back to this, I guess this doesn't really make much sense since the 4kg of dry ice probably evaporates over the race distance, so they have to be careful with being underweight. Have they had this much dry ice at every race so far, or has it only been limited to the hotter races only?
