LEAF Certification Practice Test

How does Eco mode in the 2022 Nissan LEAF contribute to extending the driving range?

1. Reduces battery usage by limiting speed

2. Provides more regenerative braking

3. Increases air conditioning efficiency

4. Enhances tire pressure monitoring

The correct answer is: Provides more regenerative braking

Eco mode in the 2022 Nissan LEAF plays a significant role in extending the driving range primarily through its enhancement of regenerative braking. When Eco mode is engaged, the vehicle optimizes its energy use by maximizing the amount of energy recaptured during braking. This means that when the driver applies the brakes or decelerates, the regenerative braking system works more effectively to convert kinetic energy back into electricity, which is then stored in the battery. This ability to recover energy directly impacts the overall efficiency of the vehicle, allowing for a greater distance to be driven on a single charge. By harnessing more energy during braking, Eco mode helps reduce the need for energy drawn from the battery while driving, ultimately contributing to a longer driving range. While options related to battery efficiency, air conditioning optimization, and tire pressure monitoring may play a role in overall vehicle performance, the most direct mechanism through which Eco mode extends range is by enhancing regenerative braking capabilities.
