N ́Evening Enthusiasts and specialists, When I once stuck myself with my polo at night in the forest, the tank indicator was long ago on 0 but in idle the colleague ran still hours with light, impulse-like heating and sometimes horns. That was already a characteristic event at that time, because I was impressed how long the car with only a few liters of fuel ran. When I hit today so on youtube my time dead I hit on a acceleration video of the W12 Phaeton. that the idle consumption was indicated with 2.4L, which is already very strange because 2.4L on 100km? You will not drive even a meter in idle, but also not with 200 liters but that’s not about it. It’s about the question not going out of my mind, how much air there is still up there. Google and search function have surprisingly also revealed nothing. Any tips or knowledge, which cars are probably drinking properly without rolling resistance? Please no hypersportsmen of Bugatti , Koenigsegg and Co. but cars, which one could actually afford, are finally here in the Kaufberatungsforum.
