How can you save fuel if you drive a car with an automatic gearbox?

Your answer is correct because both measures are effective for saving fuel in a car with an automatic gearbox. Avoiding hard acceleration when starting reduces unnecessary fuel consumption, as smooth starts require less energy. Using the eco mode optimizes the engine and transmission settings to prioritize fuel efficiency over performance. On the other hand, switching off the engine while driving, such as when going downhill, is not allowed and unsafe, as it disables power steering and braking aids. Therefore, the best ways to save fuel are gentle acceleration and using eco mode.
