Here is a current situation in my Touareg and its fuel consumption.
Mods:
- lowering springs
- Installed smooth undertray (whole underside)
- flat hubcaps
- grill block
- tire front air defletors
- Rear muffler removed
- Tire pressures to sidewall max which is 3,8 bar at the moment
- my own ecu remap program
- no spare wheel
- lighter BMW E46 16"16" alloys (5x120)

With the kind of range you have developed I would carry a lot less fuel to remove weight. Also if you had run flat tyres you could get rid of the spare wheel. And if you don't carry passengers remove the rear seat!

I dont have spare at the moment. and put that also to mods. Also my wheels are lighter. Rear seat will be taken out due to taxation reasons.
100kg weigth reduction means about 0.05-0.1 liter fuel consumption improvement. Aerodynamics are the main key to low fuel consumption.


Big tank is one reason to have this car, because diesel is in finland 1.4€ per liter, but if I fill at russian side of border its around 0.6€ per liter. So bigger tanks means bigger savings.
