How can I lower my Audi A2's fuel consumption?

I recently purchased an Audi A2 and noticed that its fuel consumption is higher than expected. What can I do to improve its efficiency?

Regularly maintain your car and keep the tires properly inflated. A well-maintained car and properly inflated tires can greatly improve your fuel efficiency.

Avoid aggressive driving and speeding. Accelerating and braking too harshly can result in higher fuel consumption. Keep a steady speed and use cruise control when possible.
