How can higher speed affect fuel or energy consumption?

421. How can higher speed affect fuel or energy consumption?

It reduces aerodynamic resistance.
It improves tyre efficiency in every situation.
It has no effect once the vehicle is moving.
✓ It can increase consumption because air resistance rises.

As speed increases, aerodynamic resistance generally rises, so the vehicle needs more energy to maintain that speed. Driving smoothly at an appropriate speed can therefore reduce fuel or energy consumption.
