How can you improve fuel efficiency while driving a Class B vehicle?

• A. Maintain steady speeds, avoid rapid acceleration and braking, and keep tires properly inflated.
• B. Keep windows open to increase ventilation.
• C. Idle the engine to warm up.
• D. Use the air conditioner on high continuously.

Answer: (A)

Smooth, steady driving saves fuel because it keeps the engine near its efficient operating range and avoids wasting energy on rapid throttle changes. When you accelerate quickly or brake hard, you burn more fuel than when you coast or accelerate gently. Anticipating traffic, easing into acceleration, and braking smoothly help you maintain a more constant speed and use less fuel over the trip. Keeping your tires at the recommended pressure reduces rolling resistance. Underinflated tires make the engine work harder to move the vehicle, which lowers fuel economy. The other options waste fuel for specific reasons: opening windows increases aerodynamic drag, especially at higher speeds; idling to warm up just wastes fuel without moving the vehicle; and running the air conditioner on high continuously adds load to the engine and uses more fuel. So for better fuel efficiency in a Class B vehicle, drive smoothly, anticipate stop-and-go conditions, and keep tires properly inflated. Use AC sparingly and plan trips to minimize unnecessary idling.
