If a vehicle experiences harsh braking, how does it affect fuel consumption?

Harsh braking generally leads to increased fuel consumption. When a driver brakes suddenly or harshly, the vehicle’s momentum is disrupted, causing the engine to work harder to regain speed once the vehicle accelerates again. This additional energy required to accelerate after a sudden stop means that more fuel is consumed compared to a smoother driving style.

Moreover, frequent harsh braking can cause the engine to operate less efficiently overall, as constant stopping and starting can lead to a less optimal fuel-air mixture and can decrease the vehicle’s fuel efficiency. Additionally, prolonged harsh driving behaviors can result in wear on the vehicle's components, further affecting efficiency over time.

Smoother driving habits, which include gradual acceleration and deceleration, can help to maintain a more consistent speed and reduce fuel consumption, highlighting the impact that driving behaviors, such as harsh braking, have on fuel usage.
