What is the best way to improve fuel efficiency in the Volkswagen ID.4?

I recently purchased a Volkswagen ID.4 and am concerned about its fuel efficiency. What steps can I take to improve it?

Regular maintenance such as keeping your tires properly inflated and changing your air filter can greatly improve fuel efficiency.

Consider using a fuel additive or switching to a higher octane fuel to see if it improves your fuel efficiency.

Try driving at a consistent speed and avoiding excessive acceleration and braking.

Using cruise control on the highway can help maintain a steady speed and improve fuel efficiency.
