The Mercedes-Benz AMG GT does 19.3 mpg combined (17.2 city, 23.1 highway), which works out to about $1,990 a year in fuel at $3.20 a gallon and 12,000 miles. Engine choice matters more than you'd think: 2L 4-cyl Hybrid does 22 mpg while 4L 8-cyl does 17.6 — a difference of $437 a year. Against other V8 cars it sits above the average of 15.6 mpg.
Every Mercedes-Benz AMG GT engine, compared
Picking the right version of the same car often saves more fuel than picking a different car altogether. Yearly cost assumes 12,000 miles at $3.20 a gallon.
| Engine | Combined | City / Highway | Years | Fuel per year |
|---|---|---|---|---|
| 2L 4-cyl Hybrid | 19 / 27 | 2025–2026 | $1,745 | |
| 3L 6-cyl Hybrid | 19.2 / 24.3 | 2019–2024 | $1,811 | |
| 4L 8-cyl | 15.6 / 21.5 | 2016–2026 | $2,182 |
What that actually costs
Miles per gallon is an abstraction; the fuel bill is not. Here it is in money, at 12,000 miles a year and $3.20 a gallon.
| Measure | Value |
|---|---|
| Cost per mile | $0.166 |
| Fuel per year | $1,990 |
| Fuel over five years | $9,950 |
| Against other V8 cars | −$472 a year |
| EPA's own estimate | $4,042 a year |
City or highway — who is this car for
The gap between city and highway figures tells you whom the car suits. A wide gap punishes stop-and-start traffic; a narrow one means the car doesn't care where you drive it.
| Measure | Value | Reading |
|---|---|---|
| City | 17.2 mpg | $2,233 a year if you only drive in town |
| Highway | 23.1 mpg | $1,662 a year if you mostly commute |
| Gap | +5.9 mpg (34%) | Wide — this car dislikes traffic |

How we count
Fuel-economy figures come from EPA fueleconomy.gov — the same laboratory numbers printed on the window sticker. We don't adjust them; real-world consumption depends on how and where you drive.
What we add is money. Yearly cost assumes 12,000 miles at $3.20 a gallon — change either and the ranking stays, only the size of the bill moves. Cost per mile is the same figure divided out, useful when comparing a commute against a weekend car.
