Question 8173
Does driving at high speeds mean higher fuel consumption?
- No, fuel consumption is constant at any speed.
- No, if done within the established limits.
- Yes, because air resistance is stronger.
Show answer and explanation
Correct answer: Yes, because air resistance is stronger.
Yes. The faster you go, the more the air holds you back, because air resistance increases with the square of your speed. The engine needs more fuel to overcome it, even if you stay within the speed limit.
