Fuel economy at a glance

These are the EPA's official ratings for the 2024 Mercedes-Benz AMG GT 55 4matic Plus (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.

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 16 MPG
City MPG 13 MPG
Highway MPG 20 MPG
Annual fuel cost $4,300
Tailpipe CO₂ 568 g/mi

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

Driving pattern Estimated annual fuel cost
Light driver, 7,500 miles per year $2,150
Average driver, 15,000 miles per year $4,300
Heavy driver, 25,000 miles per year $7,167

Specifications

The 2024 Mercedes-Benz AMG GT 55 4matic Plus (coupe) runs a 4-liter 8-cylinder turbocharged engine paired with a automatic 9-spd, sending power through all-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.

    Combined MPG has stayed close to flat across the run. Both the earliest (2024 Mercedes-Benz AMG GT 55 4matic Plus (coupe), 16 MPG) and most recent (2026 Mercedes-Benz AMG GT 55 4matic Plus (coupe), 16 MPG) versions sit in the same range.
  • How much CO₂ does the 2024 Mercedes-Benz AMG GT 55 4matic Plus (coupe) emit?
    Tailpipe CO₂ emissions are 568 g/mi. Multiplied across a typical year of driving (15,000 miles) that works out to about 8,520 kilograms of CO₂.
  • What is the difference between the city and highway MPG of the 2024 Mercedes-Benz AMG GT 55 4matic Plus (coupe)?
    City driving returns 13 MPG and highway driving returns 20 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.
