1990 Geo Metro: MPG and fuel economy
The 1990 Geo Metro is rated by the U.S. Environmental Protection Agency at 41 combined MPG, with 38 MPG in the city and 45 MPG on the highway. That puts it well above the average for cars in the Subcompact Cars class in the same model year.
This page collects every fuel-economy figure the EPA publishes for the 1990 Geo Metro. Below you will find the headline combined, city, and highway MPG, the estimated annual fuel cost at three different driving levels, the tailpipe CO₂ emissions, and a full breakdown of the engine and drivetrain. The EPA rates 2 separate variants of this car (different engine, transmission, or drivetrain combinations), and you can compare them side by side in the trims table. If you want to know whether this generation got more or less efficient over the years, the year-over-year table further down covers every model year the EPA has rated.
Key takeaways
- Returns 78% better combined MPG than the average car in the Subcompact Cars class for the 1990 model year (23 MPG class average).
- The most efficient car in the Subcompact Cars class for the 1990 model year is the Geo Metro XFI at 47 MPG.
- The Geo Metro has lost 7 MPG since its first rated model year, the 1989 Geo Metro at 47 MPG. That is often a sign of larger engines or heavier curb weights in newer generations.
- EPA estimates this car saves around $3,500 in fuel over five years compared with an average new vehicle of the same model year.
Fuel economy at a glance
These are the EPA's official ratings for the 1990 Geo Metro. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
When the EPA tests several variants of the same nameplate (for example, a front-wheel-drive version and an all-wheel-drive version), each gets its own rating. The figures shown here are the headline variant, taken as the configuration with the best combined MPG. The trims table further down covers all 2 variants side by side.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).
| Combined MPG | 41 MPG |
| City MPG | 38 MPG |
| Highway MPG | 45 MPG |
| Annual fuel cost | $1,450 |
| Tailpipe CO₂ | 217 g/mi |
| Fuel type | Regular |
How the 1990 Geo Metro compares
The 1990 Geo Metro returns 41 combined MPG. Cars in the Subcompact Cars class for the same model year average 23 MPG, which puts this car ahead of the class average by about 78%.
The most efficient car in the Subcompact Cars class for the 1990 model year is the Geo Metro XFI at 47 MPG. The bar chart below puts the Geo Metro alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 1990 model year (across all classes) returns 19.1 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 1990 model year is on its own page.
Trim variants rated for 1990
The EPA rates 2 separate variants of the 1990 Geo Metro. The differences come from the engine size, transmission type, and drivetrain (front-wheel drive, all-wheel drive, and so on). The same nameplate can land several MPG apart depending on the configuration you actually buy.
The most efficient configuration on this page returns 41 MPG, while the least efficient returns 33 MPG. That is a spread of 8 MPG between trims of the same nameplate.
| Engine and transmission | Drive | Combined | City | Highway | Annual cost |
|---|---|---|---|---|---|
| 1L, 3-cyl, Manual 5-spd | Front-Wheel Drive | 41 MPG | 38 MPG | 45 MPG | $1,450 |
| 1L, 3-cyl, Automatic 3-spd | Front-Wheel Drive | 33 MPG | 31 MPG | 36 MPG | $1,800 |
Annual fuel cost across driving patterns
The headline annual fuel cost the EPA publishes assumes 15,000 miles of driving per year and a fuel mix of 55% city and 45% highway. The dollar figure is calculated using the EPA's current reference price for regular gasoline, which is $3.99/gallon. EPA updates that reference periodically rather than tracking live pump prices, so treat it as a window-sticker estimate rather than today's pump number.
The table below scales the EPA's number to three common driving patterns. The combined MPG and the reference fuel price stay constant, only the annual mileage changes. To get a current-prices estimate, take your local gas price and multiply by 365.9 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $725 |
| Average driver, 15,000 miles per year | $1,450 |
| Heavy driver, 25,000 miles per year | $2,417 |
Year-over-year MPG for the Geo Metro
The EPA has rated the Geo Metro across 9 model years, from 1989 Geo Metro through 1997 Geo Metro. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.
The 1989 Geo Metro returned 47 MPG. The most recent 1997 Geo Metro returns 40 MPG. That is a drop of 7 MPG over 8 model years. Newer trims that grow heavier or carry larger engines tend to lose efficiency even as the rest of the lineup improves.
| Year | Combined MPG | Open year page |
|---|---|---|
| 1997 | 40 MPG | 1997 Geo Metro |
| 1996 | 40 MPG | 1996 Geo Metro |
| 1995 | 40 MPG | 1995 Geo Metro |
| 1994 | 40 MPG | 1994 Geo Metro |

Specifications
The 1990 Geo Metro runs a 1-liter 3-cylinder engine paired with a manual 5-spd, sending power through front-wheel drive.
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
