Does driving in the rain consume more fuel?
1 Answers
Driving in the rain does consume more fuel than usual. According to the vehicle's onboard computer display, fuel consumption increases by nearly 1 liter per 100 kilometers compared to sunny days. There are several possible reasons for increased fuel consumption in rainy conditions: 1. Traffic congestion is more common during rain, leading to lower average speeds and potentially more frequent braking. 2. Water accumulation on the road increases tire rolling resistance - the deeper the water and the higher the speed, the more noticeable the impact on fuel economy. 3. Air density is higher during rainy weather, which may increase wind resistance acting on the vehicle and consequently affect fuel consumption. 4. Additionally, energy-consuming features like defoggers, heated mirrors, and windshield wipers may ultimately contribute to higher fuel usage.
