By what percentage can driving smoothly reduce fuel consumption?

Answer: C — 15%

Driving smoothly can significantly enhance fuel efficiency, allowing vehicles to maintain optimal engine performance while minimizing unnecessary fuel consumption. When drivers accelerate gently, maintain steady speeds, and anticipate stops, they utilize less fuel compared to erratic driving behaviors such as rapid acceleration or frequent hard braking. Research shows that smooth driving can reduce fuel consumption by about 15%, striking a balance between efficiency and vehicle responsiveness. This percentage highlights the significance of adopting fuel-efficient driving techniques, not only for cost savings but also for reducing environmental impact. By focusing on maintaining a consistent speed and avoiding unnecessary idling, drivers can recognize the tangible benefits of more mindful driving habits in terms of fuel efficiency.
