Polyphony should position the fuel tank in the correct place on the car and tank capacity for each vehicle should be correct. That way the weight of the fuel would have an effect on the cars balance as it begins an event with a full tank and burns off over the duration. Effectively the weight of the fuel would act as a ballast (for good or for worse).

Edit - (Just to clarify, i know that fuel depletion is already a feature of the game but what i am proposing is that the position of the tank be accurate so the weight of the fuel would either add weight to the front, rear or where ever the tank is positioned in the car).

Also, you should be able to decide how much fuel to begin an event with. For example, in a practice session you wouldn't necessarily want a full tank if you are simply trying to get a fast lap time.

A rough guide would be useful indicating approximately how many kg of fuel are required per lap of the current selected track.

As it stands i think i am right in saying every car has a 60L (corrected by SHIRAKAWA Akira - each car has a 100L tank) fuel tank and is full at the beginning of every event as default with no way to change this.

What do you think? What are your opinions?

--------------------------------------
Edit--
Points made:

1: Fuel tanks are positioned in the correct place on the vehicle which affects weight distribution.

2: Tank capacities are accurate for each vehicle / tanks can be upgraded to racing fuel cells with larger capacity.

3: Fuel economy is accurate for each vehicle.

4: Option to choose how much fuel to begin an event with.

Fuel weight has already a significant effect on the car balance when fuel depletion is enabled. Currently all cars have 100 liters fuel tanks (roughly 75 Kg weight), meaning that light cars are those affected the most and this might explain why they are most of the time in disadvantage to heavier cars with the current PP system, which doesn't seem to take fuel weight into account.

It would be useful to have selectable fuel loads. But also if all cars came with proper fuel tank sizes, with an optional tuning part to upgrade them to standard racing ones (100/120 liters).
 
Thank you for correcting my tank size figure. Interesting, I like the idea of having upgradable tank sizes. I hadn't thought of that.
 
Many low powered cars, especially vintage ones such as the old Fiat 500 have really small fuel tanks (22 liters in this case), so upgradable fuel tanks are a must if more realistic fuel tank capacities will be included at some point.
 
Eh? So is a Kart that weighs 85kg, carrying 100 liters of fuel too? Thus doubling it's weight? Surely the tanks arent all the exact same? From memory, a Kart in real life has a >5 litre tank.
 
For clarity:

Water weights 1 g/cm3.
Gasoline weights roughly 0.75 g/cm3 on average.
So, 100 liters of gasoline weight about 75 Kg.

Diesel fuel gas a heavier specific weight, but I don't think this difference is modeled in GT5. There are very few [badly modeled] diesel-engined cars in-game, anyway.

I just made a test, but it's not conclusive as I haven't had time to finish it.
Karts have a 10-12 liters fuel tank in GT5 (at 3/4 tank the game told it would take 3 liters to fill it, but it might have been 2.5 rounded off to 3). They are a very special case, no other vehicles to my knowledge come equipped with a different fuel tank size than 100 liters.

10 liters would be a 7.5 Kg payload.
 
If I'm not mistaken GT4 had an option to set how much fuel you wanted to race/drive your car with.

That would be really useful on GT5.
 
I don't remember that in GT4, but I have the Japanese version which has got some differences compared to western ones.

EDIT: By the way, I'm testing the 125cc Racing Kart on SSRX, and after 2 laps (~60 Km) at just less than 50% fuel tank I could only refuel 4 liters. Maybe it's got a 6-8 liters fuel tank or an even smaller one (5 liters?). Fuel consumption for this vehicle seems too low by the way.

NO! No, no, no, no! :)

The Ford GT, with it's impressive fuel economy would have to pit after two times around Nurburgring! EDIT - ok, maybe three.

I do alot of karting myself and my tank is around about 6 litres... not sure, but it looks like the GT5 Kart tank would be around 6-8 litres, based on your posts. Though, it doesnt really tie in with earlier, your tank was 75% and you could add 3 litres (<12 litre tank) but at 45(?)% you could only add 4 litres (<8 litre tank). The game must obviously round the litres, so I guess we can assume that the tanks are approximately 7-9 litres???
