How would you ensure economic fuel consumption?
- Correct answer: By shifting to the appropriate gear and maintaining a moderate driving speed of up to 90 k.p.h.
- By driving in low gear and maintaining a driving speed of more than 120 k.p.h, without any aggressive accelerations or decelerations.
- By shifting as much as possible to neutral gear while driving downhill.
- By driving in low gear and maintaining a driving speed of more than 90 k.p.h.
Why this is the answer
The correct answer in the official bank: By shifting to the appropriate gear and maintaining a moderate driving speed of up to 90 k.p.h.
Driving in the gear that suits your speed keeps the engine turning at an efficient rate, and a moderate speed limits air resistance, which rises sharply at high speeds. Using a low gear at high speed over-revs the engine and wastes fuel. Coasting downhill in neutral is dangerous, because you lose engine braking and some control of the vehicle.
