Fun fact: heat is, generally, the ultimate factor which limits performance. It limits your engine power (air density), your braking (pads/rotors/fluid), your tire/tyre grip (rubber/air temp), suspension grip (damper oil), and the driver themselves. Compensating for heat induces drag, takes away from downforce, can compromise on engine power, increases the weight of brakes, tires, radiators, intercoolers, shock cooling, and driver cooling. Heat is also responsible for a significant amount of wear on parts. In the end, you're usually fighting heat to go faster.

[@Moribax85]

a similar argument can be made for the opposite of heat, cold, since if it's too cold the engine wouldn't work properly, brakes would slip, tires wouldn't provide enough grip, and so on. so, why not just call it "temperature"? :)

[@T-tb8ho]

Moribax because heat is referring to Heat energy, either a lack or abundance of it. More of an engineering way of saying temperature

[@sourabhk2373]

what is a reverse grid?

[@reaganharder1480]

@@sourabhk2373 reverse grid, as far as I know, is a system where championship leaders start at the back of the grid, instead of their starting position being determined by a Qualifying session. That way you have to actually make moves and pass cars in order to win a championship, and most likely evens the playing field a little for worse teams. You can argue it's unfair to the best teams, but at least you don't have every race expecting a Mercedes 1 2.

[@aurktman1106]

Scott O I think most know they will be in the middle so they try to strike a balance. The weaker PU runners (Ferrari and Renault) probably put out the same amount of heat as the Merc, but since they lack the power they are forced to have a more robust radiator/cooling system. Until they can get the power up to Merc level, they will be stuck with the cooling issues.

[@patrickconlon140]

This was so informative thank you

[@frasmit]

Great vid as always! I just feel there is one point which wasn't mentioned, which is the so called ban on party modes. By not allowing the merc's to alter their PU performace settings/maps, they couldn't clock it down to cool it down some, and then back up to quali mode and race past whomever is in front of them. This meant that even if Bottas dropped back far enough to cool the car, he would still not be fast enough when getting back behind them to overtake them, and the cycle just repeated. He said on the radio "we can't race with these settings" and I believe he was referring to the fact that he was not allowed to change the car to better suit the situation.

[@jacobaxton6353]

I think another possible cause is simply the black livery. You saw the same issue with Haas, among many other issues, last year. The livery looks incredible, but black absorbs all light, and thus heats up much quicker than other colors. Its probably a small effect in the grand scheme of things, but it contributes nonetheless

This is part of the reason I support reverse grid qualifying. Mercedes would need to design cars to go through the pack. They'd likely still be the fastest car on the track, but it'd slow them down a bit, and it would be exciting to watch them fight to the front, even if it's just qualifying.

The problem we saw that the Mercedes cars had last race does make sense on what we saw earlier this season or last season. I talking about that they (Or any of the other teams) may not be able to get their engine to perform well when in a race weekend with unusual high air termperature. I think it was last year where Ferrai had problems in the quali on Bahrain because of unusual high air temperature. I also remember that I talked with a mechainicer that also talk me that in theory a car engine works best if it gets large amount of cold air, because it can give off the heat faster. But of course in reality it doesnt work like that as the air will get hotter depending on where or how it goes around

Catchy song at the end of the video.....❤ Love from India....🇮🇳

[@CAepicreviews]

Like the video - but I'm going to correct you on that - The ICE doesn't explode gas. That's pinging. That destroys your engine very quickly. (Ignore SkyActive X for the moment) An ICE needs a controlled burn of the injected fuel. The fuel gets injected and vaporized into a fine mist (as only aerosolized gas can burn, liquid fuel cannot), the fired spark creates a kernel which turns into a flame-front that propagates outward and consumes all the injected fuel before exhaust can begin. (In a perfect world, at least) but yes, immense heat. A normal engine idling without any coolant will meltdown within 10 minutes. Let alone one that idles close to most road car's redlines.
