Fuel economy at a glance
These are the EPA's official ratings for the 2003 Aston Martin DB-7 GT Volante. 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 | 11 MPG |
| City MPG | 9 MPG |
| Highway MPG | 16 MPG |
| Annual fuel cost | $6,300 |
| Tailpipe CO₂ | 808 g/mi |
| Fuel type | Premium |
How the 2003 Aston Martin DB-7 GT Volante compares
The 2003 Aston Martin DB-7 GT Volante returns 11 combined MPG. Cars in the Minicompact Cars class for the same model year average 18 MPG, which puts this car behind the class average by about 39%.
The most efficient car in the Minicompact Cars class for the 2003 model year is the MINI Cooper at 25 MPG. The bar chart below puts the Aston Martin DB-7 GT Volante alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2003 model year (across all classes) returns 18.4 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 2003 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 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 1363.6 gallons (the car's annual consumption at the rated MPG).
| Driving pattern | Estimated annual fuel cost |
|---|---|
| Light driver, 7,500 miles per year | $3,150 |
| Average driver, 15,000 miles per year | $6,300 |
| Heavy driver, 25,000 miles per year | $10,500 |

Specifications
The 2003 Aston Martin DB-7 GT Volante runs a 5.9-liter 12-cylinder engine paired with a manual 6-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 2003 Aston Martin DB-7 GT Volante require premium gas?
Yes. The EPA lists the 2003 Aston Martin DB-7 GT Volante 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 2003 Aston Martin DB-7 GT Volante emit?
Tailpipe CO₂ emissions are 808 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 12,119 kilograms of CO₂. -
What is the difference between the city and highway MPG of the 2003 Aston Martin DB-7 GT Volante?
City driving returns 9 MPG and highway driving returns 16 MPG, a gap of 7 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 2003 Aston Martin DB-7 GT Volante?
The 2003 Aston Martin DB-7 GT Volante has a 5.9-liter 12-cylinder engine (EPA description: GUZZLER). -

How does the 2003 Aston Martin DB-7 GT Volante compare to the best car in its class?
The most efficient car in the Minicompact Cars class for the 2003 model year is the MINI Cooper at 25 combined MPG. The Aston Martin DB-7 GT Volante returns 11 MPG, a gap of 14 MPG. If you are comparing on fuel economy alone, the class leader is worth a look. -
Does the 2003 Aston Martin DB-7 GT Volante qualify for the gas guzzler tax?
Yes. The federal Gas Guzzler Tax applies to passenger cars rated below 22.5 combined MPG, and the 2003 Aston Martin DB-7 GT Volante 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.
