City or highway — who is this car for
The BMW 228i gives up 10.6 mpg the moment you leave the motorway — 34.1 out there against 23.5 in town, a 45% drop worth $508 a year. A wide gap punishes stop-and-start traffic; a narrow one means the car doesn't care where you drive it.
| Measure | Value | Reading |
|---|---|---|
| City | 23.5 mpg | $1,634 a year if you only drive in town |
| Highway | 34.1 mpg | $1,126 a year if you mostly commute |
| Gap | +10.6 mpg (45%) | Wide — this car dislikes traffic |
How the 228i changed over the years
The 228i peaked in 2024 at 28 mpg (24 city, 34 highway) and was at its thirstiest in 2020 at 27 — 1 mpg apart, or $51 a year in fuel between buying one year and the other. The 2024 car does 28. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
