The Audi 4000 does 20.9 mpg combined (18.8 city, 24.0 highway), which works out to about $1,837 a year in fuel at $3.20 a gallon and 12,000 miles. Engine choice matters more than you'd think: 1.8L 4-cyl does 24 mpg while 2.2L 5-cyl does 17.8 — a difference of $557 a year. Against other 4-cyl cars it sits below the average of 25.4 mpg.
Every Audi 4000 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 |
|---|---|---|---|---|
| 1.8L 4-cyl | 21.5 / 28 | 1984–1987 | $1,600 | |
| 2.2L 5-cyl | 16 / 20 | 1984–1987 | $2,157 |
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 | $0.153 |
| Fuel per year | $1,837 |
| Fuel over five years | $9,185 |
| Against other 4-cyl cars | +$325 a year |
| EPA's own estimate | $3,050 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 | 18.8 mpg | $2,043 a year if you only drive in town |
| Highway | 24.0 mpg | $1,600 a year if you mostly commute |
| Gap | +5.2 mpg (28%) | Typical for its type |
How the 4000 changed over the years
Combined figure by model year. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
| Model year | Combined | City / Highway | Engines offered | Fuel per year |
|---|---|---|---|---|
| 1987 | 19 / 24 | 2 | $1,873 | |
| 1986 | 19 / 24 | 2 | $1,829 | |
| 1985 | 18.5 / 23.5 | 2 | $1,829 | |
| 1984 | 18.5 / 24.5 | 2 | $1,829 |

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.
