City or highway — who is this car for
The BMW 335i gives up 9.2 mpg the moment you leave the motorway — 28.9 out there against 19.7 in town, a 47% drop worth $620 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 | 19.7 mpg | $1,949 a year if you only drive in town |
| Highway | 28.9 mpg | $1,329 a year if you mostly commute |
| Gap | +9.2 mpg (47%) | Wide — this car dislikes traffic |
How the 335i changed over the years
The 335i peaked in 2013 at 26 mpg (23 city, 32 highway) and was at its thirstiest in 2010 at 20 — 6 mpg apart, or $443 a year in fuel between buying one year and the other. The 2016 car does 23. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
