How do I increase fuel efficiency in my BMW 8 Series?

I recently purchased a BMW 8 Series and I love the performance, but I've noticed it's not the most fuel efficient. What are some tips or modifications I can make to improve my fuel efficiency while still maintaining the car's performance?

One easy way to improve fuel efficiency in your BMW 8 Series is to make sure your tires are properly inflated. This will reduce the amount of drag on the car and allow it to use less fuel.

Another helpful tip is to avoid excessive idling. If you're going to be stopped for more than a minute, it's better to turn off the engine. This can make a big difference in fuel consumption over time.
