Like promised i will report here. We reached Capetown, over the west - a amazing trip - with the beauty above, a LandCruiser 200 with a diesel V8, with all the electronic stuff of modern cars: Adjustable height control, 4 Zone aircon, 14 speaker JBL System - and so on.
Our weight was near 4to, we carry a roofbox and stuff above - so we dont had a good aerodynamic i guess. And we often drive smaller tracks, and not look for the good tar roads. The fuel usage is worse, when offroading.
We drove 20`500 km, the Fuel usage was 16.55l for 100 km in the mix. We spent 3703 USD for fuel.
Take the car who fits your needs, and bring a good travel-comfort - and dont look to the fuel usage.
We dont watch the fuel-usage, we watch the people, the environment and the animals.
