External Environment
Under unfavorable conditions, the external environment can have a
negative effect on fuel consumption. This can be broken down into two
main groups: weather and wind, and the nature of the roads. Rain,
snow, icy conditions and headwinds have a large negative impact on
fuel economy, as do hilly roads and uneven road surfaces.
Headwinds
Headwinds have a large negative impact on fuel consumption. With
tailwinds, fuel saving is only marginal.
Air Temperature
Low ambient temperature contributes to increased fuel consumption.
Rain, Snow and Road Surface
A wet road surface increases rolling resistance and, thereby, fuel
consumption. Slush will increase consumption even more. In certain
cases, the surface structure of the road can also have a negative effect
on fuel consumption.
Gradients
A hilly road with many bends demands a higher output from the engine.
The difference between flat, straight roads and hilly, winding roads can
amount to as much as a 50 percent increase in fuel consumption.
When choosing your route, avoid hills, rough roads and frequent stops.
