The EPA estimates the 2022 Mercedes-Benz AMG GT 43 4matic Plus gets 21 MPG combined, a figure that likely isn’t a major concern for most buyers. This vehicle is purchased for its striking design and strong performance from its turbocharged inline-six engine and the prestige of the AMG badge. It’s a four-door coupe that prioritizes driving pleasure and distinctive style over gas mileage.

City and highway performance

The EPA further estimates the GT 43’s fuel economy at 19 MPG in the city and 25 MPG on the highway. The lower city figure reflects the frequent stops in city driving, which reduces engine efficiency. The highway number, while not exceptional, is more respectable, partly due to the 9-speed automatic transmission shifting to higher gears for relaxed cruising. These numbers are achieved under controlled testing conditions, so driving habits and traffic conditions will significantly affect real-world results.

Annual fuel cost

The EPA estimates the annual fuel cost for driving the 2022 Mercedes-Benz AMG GT 43 4matic Plus to be $2,750. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. This is an estimate, and your actual fuel costs will change depending on how much you drive, where you drive, and the price of premium gasoline, which this high-performance engine requires.

Real-world expectations

The EPA figures offer a baseline, but expect your mileage to vary. Aggressive driving, frequent acceleration, and long periods of idling will hurt fuel economy. Owners who primarily drive in congested urban areas may see numbers closer to or below the EPA’s city estimate. However, those who frequently take long highway trips with steady throttle inputs could achieve slightly better than the 25 MPG highway figure. The AMG GT 43’s performance means that many drivers will likely not prioritize saving fuel.

How it compares

The AMG GT 43 isn’t directly competing with economy cars, but understanding its efficiency within the luxury performance segment is helpful. The BMW M850i Gran Coupe, with its more potent V8 engine, gets around 17 MPG combined. A Porsche Panamera 4S, another performance four-door coupe, gets about 21 MPG combined, similar to the AMG GT 43. Looking at performance SUVs, the Mercedes-AMG GLE 53 gets nearly the same combined MPG. These comparisons show that the AMG GT 43’s fuel economy is typical for its niche: performance luxury vehicles where efficiency is less important than power and driving dynamics. Those shopping for all Mercedes Benz fuel economy data can compare the GT 43 to other models in the lineup. You can also view AMG MPG across all years.

Tips to maximize efficiency

While gas mileage isn’t the main goal of AMG GT 43 ownership, there are ways to improve it. Avoid aggressive acceleration and drive smoothly, anticipating traffic flow to minimize unnecessary braking. The turbocharged engine responds well to gentle throttle inputs, reducing fuel consumption.

Make sure the tires are inflated to the recommended pressure. Underinflated tires increase rolling resistance, which hurts fuel efficiency. Check your tire pressure regularly, especially when the temperature changes, and inflate them as needed.

Reduce weight in the vehicle. Removing extra cargo from the trunk or rear seats can lighten the load, improving fuel economy, which adds up over time, especially during city driving.

Use the car’s driving modes. The AMG GT 43 offers modes, including a comfort or eco mode, which optimizes the engine and transmission for improved fuel efficiency. Select this mode when performance isn’t the priority, such as during highway cruising.

Maintain routine maintenance, including regular oil changes and air filter replacements. A well-maintained engine operates more efficiently, which can improve fuel economy. Consult your owner’s manual for the recommended service intervals.
