What's the best way to maintain good fuel economy in my Audi A3?

I recently purchased a new Audi A3 and I want to make sure I'm getting the most out of my fuel. Are there any specific tips or techniques I should be using to maintain good fuel economy?

First, make sure to properly inflate your tires to the recommended level. Under-inflated tires can significantly decrease fuel economy.

Avoid sudden accelerations and harsh braking. These actions use more fuel and can also wear down your brakes faster.

Plan your trips to combine errands and minimize unnecessary driving. This helps to reduce fuel consumption and emissions.
