How can be most efficient at 100kph with strong wind resistance and high rpm? Are you cvt or 4at?
misconception that driving slowly saves fuel.
if you look at charts, when the car is in the overdrive gear and going at optimum speeds, it consumes the least.
1 2 and 3rd gear consumes more petrol as they are considered "picking up" gears.
cheers bro.
you will be surprised at the fc you get when you drive normally and not extremely frugally.
i used to clock 12km/l on my latio, 30% city, 70% highway, and half the time i am on wideopen throttle and high rpms to pick up and when i reach 90km/h, i just cruise..
