The EPA’s fuel economy database covers everything from frugal subcompacts to machines that burn through a gallon in well under ten miles. The thirsty end of that range includes Italian supercars, British luxury sedans and coupes, and two full-size pickups. Here are eleven vehicles rated at 9 mpg or lower on the combined measure.
1. Lamborghini Countach: Seven Miles Per Gallon
The Countach carries the lowest combined rating in the EPA’s whole database, and its EPA fuel economy listing shows 7 mpg combined, 6 mpg in the city and 10 mpg on the highway. The same page puts consumption at 14.3 gallons per 100 miles and the annual fuel bill at $11,750 on premium gasoline.
Even the open-road figure of 10 mpg sat at the edge of double digits, so no driving pattern lifted the car far from the bottom of the table. The EPA adds that estimates for 2016 and older vehicles may have been revised.
2. Aston Martin Lagonda: The Wedge Sedan
The wedge-shaped Lagonda managed 8 mpg combined on regular gasoline, according to its EPA comparison page. The city rating was 7 mpg and the highway rating 9 mpg, which works out to 12.5 gallons per 100 miles.
The gap between city and highway was just two mpg, so a long motorway run did little to rescue the sedan’s fuel use. The listing names regular gasoline as the fuel and shows no annual cost, so the mileage figures are the main evidence of the car’s thirst.
3. Ferrari F50: Halo Car Thirst
Ferrari’s 1995 halo car earned an EPA rating of 8 mpg combined, with 7 mpg in the city and 10 mpg on the highway. Consumption comes to 12.5 gallons per 100 miles on premium gasoline.
That puts the F50 level with the Enzo and several older luxury models on the same measure. A 7 mpg city rating means a drive through town burned more than a gallon every seven miles, a pattern an owner would notice at every fill-up.
4. Ferrari Enzo: Ten Thousand Dollar Fuel Bill
The Enzo was rated 8 mpg combined, and its fueleconomy.gov entry estimates $10,300 a year in premium fuel. City driving came in at 7 mpg, while the highway rating of 12 mpg was the best of the front group.
The listing names premium gasoline, so the annual cost reflects the pricier grade on top of the poor mileage. A combined 8 mpg works out to 12.5 gallons per 100 miles, a rate of use that an owner would see in how often the car needed fuel.
5. Maserati Quattroporte: Italian Sedan, 1986 Style
Maserati’s 1986 sedan was rated 8 mpg combined on regular gasoline, as its official EPA listing shows. The agency recorded 7 mpg in the city and 10 mpg on the highway, equal to 12.5 gallons per 100 miles.
Unlike the mid-engined Ferraris, this four-door ran on regular fuel, which spared its owner the premium surcharge. The listing carries the standard caveat that estimates for 2016 and older vehicles may have been revised since first publication.
6. Rolls-Royce Camargue: Drinking Regular at 8
The Camargue drank regular gasoline at 8 mpg combined, based on its EPA mileage record. City driving returned 7 mpg and the highway 10 mpg, for 12.5 gallons used every 100 miles.
Rolls-Royce built the coupe for effortless cruising, but the highway rating of 10 mpg left little room for long-distance economy. As with other older entries, the EPA says its estimates for 2016 and older vehicles may have been revised, so the 8 mpg figure is best read as the agency’s published record for the coupe.
7. Bugatti Chiron Super Sport: Super Sport, Single Digits
The 2022 Chiron Super Sport was rated 9 mpg combined, and the EPA ratings page lists 8 mpg in the city and 11 mpg on the highway. That equals 11.1 gallons per 100 miles on premium gasoline.
As the newest model year on the list, it shows the single-digit rating persisting well past the older entries. The same page also hosts unofficial owner estimates, which the EPA treats as separate from its own measured figures.
8. Ferrari 550 Maranello: Front-Engined Ferrari
The front-engined 550 Maranello was rated 9 mpg combined, according to its EPA fuel economy data. City driving came in at 8 mpg, the highway at 12 mpg, and consumption at 11.1 gallons per 100 miles on premium.
A grand tourer is meant for long drives, yet the 12 mpg highway figure shows how little the long-legged layout helped. The listing notes that estimates for 2016 and older vehicles may have been revised, and the 9 mpg combined figure is the agency’s published record for the car.
9. Dodge Ram 1500: Not an Exotic
Not every entry is a supercar: the 2005 Ram 1500 two-wheel-drive pickup was rated 9 mpg combined, per its EPA vehicle listing. The city figure was 8 mpg, the highway figure 11 mpg, and the range on a tank 234 miles.
The listed total range of 234 miles is the figure a pickup owner would feel most, since it caps how far one tank goes. The entry shows that everyday trucks, and not only exotics, produced single-digit combined ratings.
10. Chevrolet C1500: Full-Size Pickup, 1990
The 1990 C1500 full-size pickup was rated 9 mpg combined on regular gasoline, and the EPA listing for the C1500 shows 9 mpg in the city and 10 mpg on the highway. Consumption works out to 11.1 gallons per 100 miles.
With only a single mpg between its city and highway ratings, the truck burned fuel at nearly the same rate in any kind of driving. It is the oldest pickup on the list and one of two Detroit trucks here.
11. Rolls-Royce Silver Spirit: The Quiet Fuel Hog
The Silver Spirit was rated 9 mpg combined on regular gasoline, and its EPA fuel economy page lists 8 mpg in the city and 10 mpg on the highway. That is 11.1 gallons per 100 miles.
The 10 mpg highway rating gives the sedan little room for long-distance economy, and the listing shows the same 8 mpg city rating as several other entries here. As with the other older entries, the agency says estimates for 2016 and older vehicles may have been revised.
