I have always thought about it but never got to posting it, but isn't it a bit odd that all cars have 100 liter tanks and then cars of similar classes all run out of fuel at the same distance?

I would like to test this out a little and categorize cars by distance ran, tires used, and where it would've ran out if it had the actual fuel tank for the car. I just think it boggles my mind GT can't get something as easy as this right...

AAANDDDD!! If we were to ever get an update of something of the sorts, they would need to make the fuel be totally exhausted at a certain point, similar to where it would IRL, as I don't want the same deal to happen to the tires, as they degrade way too unrealistically fast..

100 liters? What car in game has that large a tank? I remember driving the Viper on Willow and when I pitted it took on 21 liters of gas and ran out just before the line so at most it may have held 50 liters when full probably less as it used 1/4 tank in 1 1/2 laps

The tires degrade so fast because of the accelerated tire wear and fuel usage they have enabled on the later races. Online there are more than on option one tire wear and fuel usage. I think it works out pretty well actually

All cars have one hundred liter tanks. Look at em..

And I'll change the OP but I meant for tires and such to be placed online at normal wear.
 
I have did only a little racing so far online with tires and fuel on but in just the little I did I have noticed that there is definitely a difference in the fuel usage of various cars, even those that are similar in type and performance. Viper vs Ford GT for example, Viper uses more fuel and is harder on tires, I forget now which cars we were driving in the various races but we ran several different cars at willow springs in the 500-600 pp range and seemed like all of them were a bit different on fuel usage even those which were very close to the same car.

Of course it also depends on how you have the car geared and how you drive it as well.

I also did not try normal tire wear. I would think it would take a long time to run out of fuel in that mode though as even with the thing set to very fast several of the cars could complete 10 laps around willow without stopping for fuel
 
All cars have 100 liter tanks. And obviously all cars are using petrol. The diesel cars like the Audi R10 or R18 have basically the same fuel consumption as petrol LMP cars. Only the lower power of the R18 gives it a small advantage, but this would be the same if it was a petrol car.
And I would be surprised, if the difference in density between petrol and diesel is taken into consideration. A full 100 liter tank probably puts the same weight to every car.
The whole fuel topic is very simplified in GT.
 
I have wondered about this too. I thought it would have been cool if the fuel capacity of each car were realistic. Then you could buy a fuel cell for better weight distribution or an endurance fuel tank for long races.

Fuel consumption is based on horsepower, more hp uses more fuel, lower hp uses less fuel. In GT5 the 100,000hp red bulls would run out of fuel in 15 seconds at full throttle.

Correct, which I believe is totally wrong for PD to do. If we get the (well we never will but use this for the time being) Porsche 918, which has some 600+ hp and gets up to 40 mpg at times.. It will be a joke to see it go off of hp

I think it would be too complicated for them to make each cars mpg realistic, over 1200 cars and then mods, rpms, engine load would all have to be incorporated somehow. I'd rather have them focus on engine sounds more than anything else.

I would as well but this is just as big of an aspect to driving as sounds. It is something that's gone unnoticed and needs to be changed if we are expecting a true simulator...
 
Yeah it must be in percentage. There is no way stock Honda Fit would have 100ltrs on the tank, LOL
It was 40ltrs IRL
 
Still think it is good they use power/rpm for fuel consumption.

What else would you use ?

You can't use manufacturer numbers for racing.
Also how would you correct for tuning ?

That 918 with 40mpg is a good example, no chance in hell you come any close to this on a racetrack.

Veyron has officially 24l/100km, but i think it is well known it uses up to 100l/100km.
Or runs out of fuel in 15min @VMax (100l tank)

My 100hp Fiat 500 1.4 uses ~6,5l/100km on paper, my actual max. over a tankload was 19l. (Trackday/safety training)

Alfa 147 GTA (3,2V6, 250hp) has propably ~12l on paper, i know people that got it over 40l on a trackday.

On a racetrack where you use always full throttle and never partial load fuel comsumption is mainly related to max. power.
Capacity, type, turbo/na, age and so play much less role than in normal traffic.

Edit:
This is for road cars mainly, for LMP and other race cars there should be data availible from races to get the fuel consumption close to real (and tank size).

Regarding fuel milage:
I don't know how GT6s system works, but I always thought it was dependent on (total) power output of the car you use. I did the 24 min Spa race 3 times with 3 different LMP cars (908, Bentley, R18). The Audi was stock, other ones had turbo and IIRC ~720PP (Audi had ~626). I got the same mileage with the 908 and Bentley, both cars could finish the race in 2 stops. My R18 did it in 1 stop.
 
They should at least have different factors for petrol and diesel cars.

But that's one of the general problems with GT: There are more than a thousand cars in the game, but they are really just graphic models with a few data points. It's just too many to really implement the individual characteristics of all those cars. Not even the correct fuel tank size made it into the game.

@Dutchyfutch and @pakiman740 sorry for off topic, but are you guys planning on going to the Boston Auto Show?

I just moved to somerville, got slot of **** to do in the house lol no time at the moment :(

On topic :
I just still don't understand how some cars with lower go run out faster , also my hsv goes like 12k rpm and runs outta fuel slower than the Fxx while it has more power x higher rpms
 
Tire wear und fuel consumption in the S class events is in no way realistic. PD simulated it, so you must pit once in those races.

Really i was like wtf!??! 3 Laps on Nurb 24h and my tank is empty?! That are about 80km!
 
I began a discussion about this back in the GT5 section a while ago. basically for a 'simulator' GT6 should already -

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. (I dont want to time attack with 100litres of heavy fuel sloshing around)

haha sorry for not replying sooner
 
So..... I think 1.03 increased the fuel rate for my R18, as now on slow/normal/whatever setting Im getting three laps (including out lap) and it is reaching a quarter empty, and I do believe pre 1.03 I was only at 1/8th empy.... I wish I saved a replay..
