These comments are hilarious. Why try to make scientific arguments when you clearly have no idea what you're talking about? Without using any big words, engineering/thermodynamic principles let's think about it logically...

Spin your arms around at 100rpm. Not bad, a little effort but not too bad.
Now hold 50 lb weights in your hands, spin your arms at 100 rpm. By your logic, it should take the same amount of work... I sincerely hope that common sense would tell you this is not true.

Indeed.

Look at a more direct analogy. How much throttle does it take to keep your car redlined in neutral? 10%? How much does it take in fourth gear? 100%+?

The gearbox puts load on the engine. It takes more power, and thus more fuel to keep your RPMs up the higher the gear you're in.


(What I want to know is, does the F10 have a much larger fuel tank than the F2007?)
 
Let's say it's the load, not the gear.
You can use constant 100% throttle in any gear if you use the brakes at the same time.
 
I read everything.

And the SIZE of the fuel available is an indication that the overall physics engine i stoo somplisti cto take complex fuel consumption into the mix.


And whether you choose to understand thi sor not, but fuel tank size has a DIRECT impact on vehicle dynamis and thu sis a CORE part of the physics engine and its ability to accuratelt simulate a car.

The fuel has weight.

The fuel has movement and thus dynamically im[act the cars COG and COM.

So - IOW I am correct in my statement that simly tossing ins a 120l tank wihtou REGARD for its impact on th eover all physics is yet again and indication that the GT engine is not very "real".

Unless in your world fuel has no weight.... ??

NOPE fuel tank size doesn't have anything to do with a physics engine. The physics engine simply calculates based on given parameters. How much weight and where it is placed is a parameter. Inaccurate fuel quantities has NOTHING to do with the physics engine. You shouldn't even be saying the words 'physics engine' in this discussion.
 
Why does everyone seem to think the cars have 120 litre fuel tanks. On my GT5 every car has a 100 litre tank...

This. I haven't seen anything other than 100 litres or 81 litres for the 908.
 
Sorry for bumping the topic, but I'm doing some tests too...

1 lap @ La Sarthe with no chicanes (about 13 kilometers)...

My 1250hp Veyron uses 12 liters to do 1 lap (about 1,1 km/l). A completelly stock '83 Civic 1500 25i with the engine rebuild do it using 3 liters... (about 4,3 km/l).

That's a huge difference... but I found the Civic particularly a small gas guzzler for its size.

Well, we have to consider that La Sarthe laps are most of the time in full throttle... need to do more tests tho.
