How can I improve the fuel economy on my Audi A1?

I've been noticing that my Audi A1 is not getting the best fuel mileage. What are some things I can do to improve its fuel economy?

Regularly check and replace your air filter. A dirty air filter can reduce fuel efficiency.

Try to avoid heavy acceleration and braking, as this can use up more fuel. Instead, try to maintain a steady speed.

Keep your tires properly inflated. Under-inflated tires can decrease fuel efficiency.
