Did you measure fuel consumption per km? Difference of gas usage by going 130 or 95 sounds way to high for me.

- saalweachter 6y agoWind resistance is proportional to the square of speed -- you experience 90% more going 130 vs 95.
- andi999 6y agoTrue, but I do not think wind resistance is 100% or your full consumption. But even if it were, then you would you 90% more fuel per hour. But in on case travel more than 30% further. But if I were to guess (at least from my car, but I will check it in the future) it is more like 6,2l/100km at 100km/h and 7l/100km at 130km/h.
- Aachen 6y ago> Did you measure fuel consumption per km? I have a configurable display that shows average fuel consumption per 100km, momentary fuel consumption per 100km, kilometers remaining with available fuel, or some other value that I forgot about. It's always set to the momentary fuel consumption and I have a good idea about how much things like grades (in/declines), wind, acceleration, etc. impact the consumption. The consumption per 100km is not the best measure for acceleration or idling (more useful would be something like "ml used in last 10 seconds"), but it give me some indication. Using the cruise control to accelerate (when safe; e.g. on steep uphill highway on-ramps you need to shift down and put that pedal down to get to a more safe merging speed) it's limited to about 8-9l/100km which is pretty good (many Germans consider such amounts normal for their cruising speed, let alone accelerating).
