From Scawen's earlier(2004, old forum) post:

Quote from Scawen :- I didn't "invent" the fuel consumption figures, the fuel being used in any physics update comes from the current power output of the engine and the amount of energy in a litre of petrol, modified by an efficiency value (30% - most of the energy is wasted as heat).

At least that was the case long before the BF1 patch. Then it came out in April 2006 and suddenly fuel consumptions of all cars had dropped by more than half if you remember. I suppose it was because of some empirical values, like we know for example that a modern V8 F1 car consumes around 75l/100km during a race according to some F1 teams. I've found the current fuel consumption of the cars a bit low, but it's not that far off, so it doesn't make much sense really, if we consider the different circumstances, measuring errors as well.

Quote from AndroidXP :By the way, did you know the side of the tyre that is exposed to wind cools down quicker?

Are you sure of that? Stay stationary with the car after a restart with wind speed set to high. All of the 48 segments of a tyre (also both sidewalls relative to eachother) cools down at the same rate, according to the changing speed of the wind. If less or no wind, then it cools down slower for sure, but the car and its parts don't have an effect on that, unlike the size of the tyre. The bigger the tyre, the longer it keeps warm.

At least that's what I see after checking.

Quote from Alfa :...
Now if something mechanical were to happen, like a flat tyre or damage to the suspension etc.. it would be cool if vibrations were modelled, the ones that rattle your eyes out of their sockets.



If you could fix your viewpoint exactly to the car in LFS -which you cannot, even if you set all force movements to 0, I don't know the reason why - you would see some blur in the background in case of a very flat tyre. If you set the movements to max, you should see the view shaking, moving up and down rapidly.

Anyway, this is from Scott Speed's recent diary (formula1.com):

Speed also spent time involved in various fascinating fields of the aviation world. He got a ride in a restored World War II B-25 bomber. He also made two trips to Budapest where he watched the Red Bull Air Races, and he had thrilling ride in an aerobatic plane with the pilot doing all sorts of manoeuvres.

“Peter, the favourite Hungarian pilot on the Red Bull team, took me up and did all the flips and twirls and tried to pull a lot of Gs,” Speed said. “For 8.5 Gs, I thought it was quite easy. The G force in an F1 car, at about 5.5, is more difficult to deal with.

“The G force in the plane, going down, is compressing your body: You don’t have to do anything. You just sit there and let it compress you. It does not hurt at all. In a car you have to really fight it a lot more.”

Another video which shows tyre deformation in action.
This time throughout a whole lap onboard with Szabolcs Róbert (LFS name:ProexRobi, who is Norbi's team chief btw) in a Renault Clio racing car, where one of the 4 cams facing backwards shows the right front tyre and suspension as the car goes into corners and riding on kerbs at the Hungaroring.
According to Norbi they used to set 2.1-2.2 bar in the Pirelli 195/45 R16 tyres which goes up to some 2.7 during a race.
