Fuel economy at a glance

These are the EPA's official ratings for the 1998 Subaru Legacy Wagon. 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.

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 24 MPG
City MPG 21 MPG
Highway MPG 29 MPG
Annual fuel cost $2,500
Tailpipe CO₂ 370 g/mi
Fuel type Regular

How the 1998 Subaru Legacy Wagon compares

The 1998 Subaru Legacy Wagon returns 24 combined MPG. Cars in the Midsize Station Wagons class for the same model year average 20.5 MPG, which puts this car ahead of the class average by about 17%.

Within the Midsize Station Wagons class for the 1998 model year, the Subaru Legacy Wagon is the leader. No other car in the same class beat its 24 MPG rating. The bar chart below shows it alongside the class average and the average new car for some additional context.

For broader context, the average new car of the 1998 model year (across all classes) returns 19.2 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 1998 model year is on its own page.

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 625 gallons (the car's annual consumption at the rated MPG).

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $1,250
Average driver, 15,000 miles per year $2,500
Heavy driver, 25,000 miles per year $4,167

Specifications

The 1998 Subaru Legacy Wagon runs a 2.2-liter 4-cylinder engine paired with a automatic 4-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.
