Do cars have different size fuel tanks?

Grinding and getting tired of refueling every two laps, even after adjusting the fuel map. Do some cars have larger tanks and if so, which is largest?
 
Any tips on better mileage, barring fuel maps?
lift and coast to braking points, plus short shifting up and holding higher gears through corners help a lot too. The last two are assuming you use manual shifting. Race cars also get better fuel mileage than road based cars.

Ways to increase fuel efficiency:

1) Pick a more efficient car

2) Decrease power levels in the car's settings

3) run a different fuel map while racing

4) short shift/run in a higher gear
 
There’s all sorts of things you can do, but the biggest I’d say is don’t use road cars in races/events designed for racing cars. Modded road cars are tempting, but racing cars get significantly improved fuel efficiency. Generally the lower the Gr. number the better fuel efficiency you’ll get. Gr.1 get better than Gr.4. If you want to single stop or no stop a race, pick a car that is lower Gr. Number than the AI and reduce power with the Restrictor to meet PP restrictions.
There are very few racing cars that require pitting every 2 laps outside of Gr.4 cars, and most of those are the Gr.B cars.

You can swap the engine and improve the fuel efficiency, if the donor car is a racing car.

That is correct. A very viable and fun option especially when grinding.

I kinda factored that in with the “all sorts of things” line as I didn’t want to go into detail explaining all the different options especially based on OP previous posts; it’s unlikely they have access to the engine swaps yet. I think you have to be collector level 50 to do engine swaps and it sounded like OP only had maybe an hour of playtime in based on their previous posts.

Weight reductions help fuel economy, decreasing drag (downforce) can help fuel economy, lowering the ECU helps fuel economy, adding ballast hurts fuel economy, permanent upgrades that raise the redline will hurt fuel economy. Of course many of these things affect performance and PP in different ways and may or may not be desirable or even make much of a difference in the game.
 
Yeah, 100L all round for petrol fuel tanks. The only exception is the kart, which is 5L.
I realise that is how it looks, but with engine swaps, I do wonder how some cars with significantly more power, also seem to have a greater range. I suspect the coding deals with a value based on percentages rather than an amount based on litres.

I can't remember which engine swaps, but when I used to use the Le Mans money earner - there were a few engine-swapped cars that could do a no-stop race. Has anyone done any fuel economy/range comparisons with engine-swapped cars?

Those swaps you are referring to are almost certainly using racing engines. The types of racing engines in the game that are being swapped into road cars are designed and built for both power and fuel efficiency because of the cars they come from and the types of races they are used in. It’s not like they’re top fuel dragster engines where they only need enough fuel to get them down the track for a single run so they don’t care at all about fuel efficiency in terms of MPG.
Also, even some road car engines, despite having more power than others, are just designed to be more fuel efficient than your average road car engine. These are usually reserved for more high end cars as the R&D and parts for them cost more than your average road car engine where 100-200 horsepower and 30 something MPGs is standard and acceptable.
 
I believe all cars have a 100 L fuel tank, regardless of what a car may have in real life.
26.5 gallons U.S. ! that is a big tank, my pos car only has 14 gallons. I remember when baaaaaack in the days (1970), my uncle's buick 225 had a 26 gallon tank.
 
Interesting that the fuel readings in % on some race car dash displays do not match up with the numbers on the HUD.

You'd think 60% of 100L would be 60L.

Have we ever gotten any sort of confirmation that it's 100 liters and not "100 unspecified units"? The latter would help...

...make more sense.

Yes - the pit lane refuel rate is listed in litres per second, and that corresponds directly to one fuel-tank unit per second.
 
To complicate matters, some cars where the dash views display fuel amount have a full-tank reading of something other than 100 liters. The telemetry software still says it's 100 liters though.

Yes, the Radical SR3 SL displays on its dashboard 76L in the full tank as the real life 77-liter aluminium tank or fuel cell I suppose.
In-game this amount is always treated as a 100L capacity fuel tank, so basically de facto modifying the refuelling speed for each car, in order to have the same refuelling time for all cars discarding tank capacity differences.

I'm of those who think that it is in fact 100 unspecified units...

I assumed it was 100% full fuel tank and some cars were either more or less efficient. I never thought about it being accurate litres or gallons. I just assumed that side of it was just 'game' mechanics rather than accurate simulation of the car's fuel efficiency. I'd seen the same as mentioned elsewhere that road cars are least efficient and GR1 cars were best.
Don't know if anyone has done any thorough research into this.
 
There are diffrent values but they have diffrent consumption like the both amg gr.3
The 2016 version hase 125 liter on display

And the 2020 version hase 73 Liter

At the end both reach the same rounds.
But in my opinion is this one of the reason why the 2020 version is faster because 52 liter or kilos less weight. In bop the 2020 car hase more weight but minus the 52liter it is slightly lighter.

Both go 5 laps in sardegna like all gr.3 cars
Gr.2 are round abound 6-7 laps. Street cars more likely 2-3 laps and they are the wors except you engine swap them.
Only way is fuelmap or less RPM to save fuel.

I use two different 930 Turbos for the 700pp race at Le Mans.

One has the standard engine (full lightweight body, tuned suspension etc) which needs FM4 to get 3 laps (FM1 gets 2.2 laps) and the same car but with the RSR engine swap and that one gives me 4 laps using FM1 for 3 of them and FM2 for the 4th. I imagine I could get all 7 at FM4 if it was a dry race and I didn’t need to change tires.
