Which of the following behaviors is known to increase fuel consumption in a vehicle?

• A. Gradual acceleration
• B. Harsh accelerating
• C. Driving at constant speed
• D. Using cruise control

Answer: (B)

Harsh accelerating is known to significantly increase fuel consumption in a vehicle. When a driver accelerates quickly and aggressively, the engine has to work substantially harder, which leads to higher fuel usage. This is because the engine operates less efficiently under heavy loads and rapid increases in speed, resulting in wasted fuel. In contrast, gradual acceleration helps maintain better fuel efficiency as it allows the engine to function more smoothly, ultimately optimizing fuel consumption. Similarly, driving at a constant speed, particularly on highways, keeps the engine running efficiently and conserves fuel. Using cruise control is also beneficial as it helps maintain a steady speed, preventing unnecessary acceleration and deceleration that can lead to additional fuel use.
