Question 8190
If you are driving on a high-capacity divided highway (autovía), turn on the air conditioning and close the windows, how does it affect fuel consumption?
- It increases.
- It decreases.
- Fuel consumption stays the same.
Show answer and explanation
Correct answer: It decreases.
At high-capacity divided highway (autovía) speeds, air coming through open windows holds the car back significantly. That is why closing them and using the air conditioning in moderation usually reduces fuel consumption, even though the system also uses fuel.
