FUEL EFFICIENCY CHALLENGE! Trying to get the best tank in my 2022 BMW M240i!

Hey everyone, this was tough to drive so "efficiently" while the weather was getting so nice. After everyone reacting to my near 14L/100 km average fuel consumption in my 3 months with my M240i video I decided to challenge myself and drive one whole tank on Eco Pro and to drive as efficiently as possible to see how much I could improve my own daily driving. The gas prices have also gone mad and it is over $2/L so that was also a motivator. I know I could have done way better if I did more highway driving or more driving in general but compared to what I was getting, not too bad! I also learned about the coasting mode and how to manually activate it. The best average I've ever achieved on a single trip was 5.8 L/100 km but that was coasting in the countryside at speeds around 80km/h in Eco Pro. Let me know what you guys think and let me know your best tank in your G42!
