Fuel consumption in Forza Motorsport 6?

I had no idea there was fuel consumption in Forza, since I didn’t see a fuel load slider in the tune set up I just assumed it was never a factor. Why on earth would they include fuel consumption without giving the player control over how much fuel is in the car? Considering this is a game where we do hotlaps, why carry around the unnecessary weight? Or, does the fuel not add weight in Forza?

Why not try an electric car?

They don’t appear to consume any charge at the moment!

I think more as a cop out to admitting refuelling would take hours (giggles)
