What's the best way to get good gas mileage in an Audi?

I recently purchased a new Audi and I want to make sure I'm getting the best gas mileage possible. What are some tips and tricks for maximizing my fuel efficiency?

One tip is to regularly maintain your car, like keeping up with oil changes and tire pressure. This can improve gas mileage by up to 4 percent.

Avoid idling for long periods of time, as this can waste fuel. If you know you'll be sitting in traffic for a while, consider turning off your engine.

Drive smoothly and avoid sudden accelerations and braking. This can improve gas mileage by up to 33 percent.
