Why are Audi A2's known for their fuel efficiency and how can I maintain it?

I've heard that the Audi A2 is one of the most fuel efficient cars out there, but I'm not sure how to maintain that efficiency. Can you give me some insight into why they are so efficient and any tips for keeping it that way?

The Audi A2's fuel efficiency is due to its lightweight design and aerodynamic shape. To maintain this efficiency, make sure to keep up with regular maintenance, such as oil changes and tire rotations. Additionally, keep your tires properly inflated and limit excess weight in the car.

Audi A2's also have a start-stop system, which automatically switches off the engine when the car is stationary, saving fuel. Another important factor in maintaining fuel efficiency is to avoid aggressive driving habits, such as rapid acceleration and harsh braking.

One helpful tip for maintaining fuel efficiency in an Audi A2 is to use the cruise control feature on the highway. This can help you maintain a consistent speed and avoid unnecessary fluctuation in fuel usage. Additionally, make sure to use the recommended octane level for your fuel.
