My M340i was able to achieve these MPG

Wife: 35.5 MPG mostly Highway Adaptive mode

Amazing numbers for an inline 6 engine..

Car has about 4500 miles on it and I'm averaging about 23mpg

Mostly drive in Sport+

3 or 4 trips to the drag strip, plenty of "fun" and testing on the streets, highways, and expressways and the majority of my daily driving is in City traffic so not idea conditions

Highway I'm seeing closer to 30mpg but dont really get on the highway much

Very pleased with my G20 mpg. Not quite the 44mpg my Accord Hybrid got but FAR better than the 8mpg my E90 got

You meant 18mpg on E90, or really 8mpg?

And 23mpg is M340i?

My 330i got 42mpg on freeways and 35-ish combined, that is only with dual storage.

I will be very interested to see 330i's mpg when it gets mild hybrid.

Lead foot and mostly city driving. I’m averaging around 25 mpg. Considering my slow-ass Tacoma only got around 17 mpg, I’ll take it.

Touring: 40mpg at 60-70mph on highway in comfort, no coasting, car loaded to the hilt (5 adults, gear to the max)

it's possible at that time air density and wind were favourable

there are quite a few factors

I'm getting ~23-26 mpg on avg for my '23 m340.

Haven't been able to creep in the mid 30s yet (got low 30s only a few times), but tbh Im in a major city and most of my 50-60+ miles trips are road trips or travel for sports. That said, I came from a Honda so I have a slightly heavy foot and extra smile when driving (50:50 mix of comfort and sport fwiw).
