Question 3895
To achieve efficient driving, you should drive...
- at a steady speed, avoiding sudden braking and hard acceleration.
- using the lowest gears as much as possible.
- continuously varying your speed, so the engine does not get strained.
Show answer and explanation
Correct answer: at a steady speed, avoiding sudden braking and hard acceleration.
You use less fuel if you keep your speed as steady as possible, without unnecessary hard acceleration or braking. Each burst of acceleration requires extra fuel, and each instance of hard braking turns energy into heat that you cannot recover. Changing your pace unnecessarily only increases fuel consumption, as does driving in low gears.
