Why is changing gears earlier considered economic driving?

• A. It allows for faster speeds
• B. It increases fuel consumption
• C. It helps maintain engine efficiency
• D. It is required by law

Answer: (C)

Changing gears earlier is considered economic driving because it helps maintain engine efficiency. When you shift to a higher gear at lower RPMs, the engine operates more efficiently, resulting in less fuel being consumed. This practice keeps the engine within its optimal power band, reducing strain on the engine and promoting smoother acceleration. Additionally, operating in higher gears typically allows the vehicle to travel at a more economical speed, contributing to overall fuel savings and lower operating costs. The other options do not contribute to the principles of economic driving. For instance, faster speeds can lead to increased fuel consumption and may not align with safe driving practices. Saying that it increases fuel consumption directly contradicts the concept of economic driving, which aims to reduce fuel use. Lastly, legal requirements regarding gear shifting do not apply in the same way; driving economically is more about efficiency rather than compliance with laws.
