最も燃費が良いのはどの速度？ 速度が燃費に与える影響を40〜120km/hで実測してみた！

Does driving slower result in better fuel efficiency? Or is there an "optimal speed" where the engine and gears operate most efficiently? This time, using a MAZDA3, we measured instantaneous fuel efficiency at 10 km/h increments from 40 km/h to 120 km/h. Fuel efficiency was recorded at the moment of passing markers placed at equal intervals. We compared the average, minimum, and maximum values ​​for sections where conditions were relatively stable and data for all vehicle speeds was available. We also checked the engine RPM at each speed and considered the reasons why fuel efficiency decreased at high speeds. *Filmed with safety in mind.
