The 1998 Aston Martin DB7 Coupe is rated by the U.S. Environmental Protection Agency at 15 combined MPG, with 13 MPG in the city and 19 MPG on the highway. That sits a little below the average car in the Two Seaters class for the same model year.
This page collects every fuel-economy figure the EPA publishes for the 1998 Aston Martin DB7 Coupe. 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
- The most efficient car in the Two Seaters class for the 1998 model year is the BMW Z3 Roadster at 23 MPG.
- EPA estimates this car costs around $12,250 more in fuel over five years than an average new vehicle of the same model year.

Fuel economy at a glance
These are the EPA's official ratings for the 1998 Aston Martin DB7 Coupe. 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 | 15 MPG |
| City MPG | 13 MPG |
| Highway MPG | 19 MPG |
| Annual fuel cost | $4,600 |
| Tailpipe CO₂ | 592 g/mi |
| Fuel type | Premium |
How the 1998 Aston Martin DB7 Coupe compares
The 1998 Aston Martin DB7 Coupe returns 15 combined MPG. Cars in the Two Seaters class for the same model year average 16.2 MPG, which puts this car behind the class average by about 7%.
The most efficient car in the Two Seaters class for the 1998 model year is the BMW Z3 Roadster at 23 MPG. The bar chart below puts the Aston Martin DB7 Coupe alongside the class best and the class average so you can see the full picture.
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.
Trim variants rated for 1998
The EPA rates 2 separate variants of the 1998 Aston Martin DB7 Coupe. 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.
| Engine and transmission | Drive | Combined | City | Highway | Annual cost |
|---|---|---|---|---|---|
| 3.2L, 6-cyl, supercharged, Automatic 4-spd | Rear-Wheel Drive | 15 MPG | 13 MPG | 19 MPG | $4,600 |
| 3.2L, 6-cyl, supercharged, Manual 5-spd | Rear-Wheel Drive | 15 MPG | 12 MPG | 19 MPG | $4,600 |
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 premium gasoline, which is $4.61/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 1000 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $2,300 |
| Average driver, 15,000 miles per year | $4,600 |
| Heavy driver, 25,000 miles per year | $7,667 |

Specifications
The 1998 Aston Martin DB7 Coupe runs a 3.2-liter 6-cylinder supercharged engine paired with a automatic 4-spd, sending power through rear-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.

Does the 1998 Aston Martin DB7 Coupe require premium gas?
Yes. The EPA lists the 1998 Aston Martin DB7 Coupe as requiring premium gasoline. Running it on regular can reduce performance and may affect engine warranties, so it is not a recommended way to save at the pump. -
How much CO₂ does the 1998 Aston Martin DB7 Coupe emit?
Tailpipe CO₂ emissions are 592 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 8,887 kilograms of CO₂. -
What is the difference between the city and highway MPG of the 1998 Aston Martin DB7 Coupe?
City driving returns 13 MPG and highway driving returns 19 MPG, a gap of 6 MPG. A spread that wide is typical of cars with conventional automatic or manual transmissions, where stop-start city traffic eats more fuel than a steady highway cruise. -
What engine is in the 1998 Aston Martin DB7 Coupe?
The 1998 Aston Martin DB7 Coupe has a 3.2-liter 6-cylinder supercharged engine (EPA description: ASTON-DB7). -
What transmission and drivetrain does the 1998 Aston Martin DB7 Coupe have?

How does the 1998 Aston Martin DB7 Coupe compare to the best car in its class?
The most efficient car in the Two Seaters class for the 1998 model year is the BMW Z3 Roadster at 23 combined MPG. The Aston Martin DB7 Coupe returns 15 MPG, a gap of 8 MPG. If you are comparing on fuel economy alone, the class leader is worth a look. -
Does the 1998 Aston Martin DB7 Coupe qualify for the gas guzzler tax?
Yes. The federal Gas Guzzler Tax applies to passenger cars rated below 22.5 combined MPG, and the 1998 Aston Martin DB7 Coupe falls below that threshold. The tax is paid by the manufacturer at the point of sale and is built into the sticker price, so you will not see a separate line item at the dealership. Pickup trucks and SUVs are exempt from this tax even when their efficiency is lower.
