Research on the Effect of Road Height Profile on Fuel Consumption during Vehicle Acceleration

Hanzl et al. Technologies. 2022; 10: 128 | Highlighted on Fuelcons

This article by Hanzl et al. addresses research on vehicle fuel consumption during acceleration and how road profiles affect it. The research specifically examined how road height profiles impact fuel consumption during acceleration, focusing on a 30-meter stretch of flat and downhill (-8.5%) surfaces. The study involved 20 acceleration tests on each type of road using a Kia Ceed vehicle. The results showed that fuel consumption during downhill acceleration was 31.4% lower compared to flat surface acceleration.
