PP similarities but huge time differences.

I wonder if the fuel tank size and fuel economy are reasons for this.

Tank size is equal to all cars in this game.
It simply is 100% with a refill rate at a fixed rate of x% per second.
It definitly would make differences for weight distribution on an empty tank and to make fuel consumption a bigger facto, I think it is set as a 100litre tank for all cars.
