¿Cree Ud. que el consumo de combustible es más bajo si el equipaje se transporta en el maletero y no en la baca de un turismo?
Do you think fuel consumption is lower if luggage is carried in the boot rather than on the roof rack of a car?
- ASí, porque la resistencia aerodinámica es menor.Yes, because aerodynamic drag is lower.
- BNo, porque el peso es el mismo.No, because the weight is the same.
- CEs indiferente. El consumo no varía.It makes no difference. Consumption does not change.
Show answer
Correct answer
- ASí, porque la resistencia aerodinámica es menor.Yes, because aerodynamic drag is lower.
Explanation
Although the weight is the same, luggage on the roof rack increases the vehicle's frontal area and aerodynamic drag, which increases consumption, especially at high speeds. In the boot, the load does not change the aerodynamics.
