The BMW 530i does 24.9 mpg combined (21.7 city, 30.4 highway), which works out to about $1,542 a year in fuel at $3.20 a gallon and 12,000 miles. Engine choice matters more than you'd think: 2L 4-cyl Hybrid does 29.8 mpg while 3L 8-cyl does 18 — a difference of $844 a year. Against other 4-cyl cars it sits below the average of 25.4 mpg.
Every BMW 530i engine, compared
Picking the right version of the same car often saves more fuel than picking a different car altogether. Yearly cost assumes 12,000 miles at $3.20 a gallon.
| Engine | Combined | City / Highway | Years | Fuel per year |
|---|---|---|---|---|
| 2L 4-cyl Hybrid | 26.5 / 34.3 | 2021–2026 | $1,289 | |
| 2L 4-cyl | 24.6 / 33.4 | 2017–2023 | $1,391 | |
| 3L 6-cyl | 18 / 27.1 | 2001–2007 | $1,794 | |
| 3L 8-cyl | 15 / 23.5 | 1994–1995 | $2,133 |
What that actually costs
Miles per gallon is an abstraction; the fuel bill is not. Here it is in money, at 12,000 miles a year and $3.20 a gallon.
| Measure | Value |
|---|---|
| Cost per mile | $0.129 |
| Fuel per year | $1,542 |
| Fuel over five years | $7,710 |
| Against other 4-cyl cars | +$30 a year |
| EPA's own estimate | $3,080 a year |
City or highway — who is this car for
The gap between city and highway figures tells you whom the car suits. 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 | 21.7 mpg | $1,770 a year if you only drive in town |
| Highway | 30.4 mpg | $1,263 a year if you mostly commute |
| Gap | +8.7 mpg (40%) | Wide — this car dislikes traffic |

How we count
Fuel-economy figures come from EPA fueleconomy.gov — the same laboratory numbers printed on the window sticker. We don't adjust them; real-world consumption depends on how and where you drive.
What we add is money. Yearly cost assumes 12,000 miles at $3.20 a gallon — change either and the ranking stays, only the size of the bill moves. Cost per mile is the same figure divided out, useful when comparing a commute against a weekend car.
