I have a 2021 with 37K KMs. Total average is 27.8. I drive mostly highway, ECO mode and some mild fun. Car is amazing on gas for what it is. When I max it out on the highway in Germany it eats fuel though.

She's definitely efficient at speed too.

Tires have the correct pressure so when I take it in for service soon I will ask them to check all the usual suspects. I will add an update if I find out what caused my sudden drop in mpg’s.

Winter gas? Where are you located?

Electrical load? Lights, heated seats, heated steering wheel etc in the cold weather?

Interesting, right now I’m grabbing 480+ each fill up , highest I’ve got was around 520-530 miles full tank, I do mainly highway driving anyhow I’m at like 28 mpg comfort but if I go sport / sport + im probably going like low 20’s depending how heavy I floor it ( M340i )

That’s not such a good mpg first tank

My mpg drops 5-10% with a new set of 4 non-BMW star all-season RFTs.

I found out that the BW star all-season RFTs(driven for 30k miles) are each 4-5 pounds less than the ones I got.

I do notice that the brand new tires seem has higher rolling resistance than my previous set of BMW star tires, and it feels to be gradually improving, so hopefully my mpg will restore back to 42mpg soon.
