The Saab 900 does 20.8 mpg combined (18.2 city, 25.3 highway), which works out to about $1,846 a year in fuel at $3.20 a gallon and 12,000 miles. Engine choice matters more than you'd think: 2L 4-cyl does 21.3 mpg while 2.5L 6-cyl does 19.3 — a difference of $187 a year. Against other 4-cyl cars it sits below the average of 25.4 mpg.
Every Saab 900 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 | 18.6 / 25.8 | 1984–1998 | $1,803 | |
| 2.3L 4-cyl | 18 / 26 | 1994–1997 | $1,829 | |
| 2.5L 6-cyl | 17 / 23.3 | 1994–1997 | $1,990 |
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 | $0.154 |
| Fuel per year | $1,846 |
| Fuel over five years | $9,230 |
| Against other 4-cyl cars | +$334 a year |
| EPA's own estimate | $2,884 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 | 18.2 mpg | $2,110 a year if you only drive in town |
| Highway | 25.3 mpg | $1,518 a year if you mostly commute |
| Gap | +7.1 mpg (39%) | 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.
