The 2022 Mercedes-Benz AMG C43 4matic Coupe’s 22 MPG combined won’t set any fuel efficiency records, but that’s not its purpose. This car hits a sweet spot in the AMG lineup, providing more performance than a regular C-Class coupe without the higher price of the C63. It values driving fun and exciting sounds over fuel savings, a trade-off most owners are happy with.

City and highway performance

The EPA estimates the C43 coupe gets 19 MPG in the city and 28 MPG on the highway. The city number reflects how easily the engine delivers strong acceleration, tempting drivers to step on the twin-turbo 3.0L V6. The highway number is good, but the car’s engaging nature can hurt it. The exhaust and quick responses make even boring highway driving feel special. These figures were achieved in a laboratory setting under controlled conditions, which often yield different results in the real world.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Mercedes-Benz AMG C43 4matic Coupe at $2,650. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, using current national average prices for premium gas. The C43 needs premium fuel for best performance. Your fuel costs will change if you drive more or less than 15,000 miles a year, or if you live where gas prices are higher or lower.

Drivers in California, where gas prices are high, should expect to pay more. Mercedes Benz fuel economy data can be reviewed to make an informed decision. all Mercedes Benz fuel economy data

Real-world expectations

In everyday driving, don’t count on getting the EPA’s 22 MPG combined number all the time. Expect around 18-20 MPG if you often drive aggressively, as most owners will. Getting the EPA’s 28 MPG on long highway trips is possible if you drive carefully.

AMG MPG across all years is usually lower than other Mercedes-Benz vehicles because of their performance. This car isn’t made to save gas. It’s made to be fun to drive, which means using more gas.

How it compares

The AMG C43 is in a competitive group with the Audi S5 Coupe and BMW M440i xDrive Coupe. The Audi S5, with its turbocharged V6, offers similar performance and luxury, with an EPA combined rating of 24 MPG. The BMW M440i xDrive Coupe gets 25 MPG combined, making it the most fuel-efficient of the three. For buyers in this class, these differences matter less than styling, how the car feels, and the brand.

The C43 buyer wants the Mercedes star and AMG badge, and they’ll accept slightly worse gas mileage to get them.

Tips to maximize efficiency

You can still improve the C43’s gas mileage by driving carefully, even though it’s a performance car. Don’t accelerate or brake hard, since this uses a lot more fuel. Apply a light pressure to the gas pedal, and watch traffic to keep a consistent speed.

Driving modes can also help you save gas. Using “Comfort” mode softens the throttle and tells the transmission to save fuel. You might lose some of the car’s sporty feel, but it can make a difference on longer drives, especially on the highway.

Maintenance is always important, including tire pressure. Keep your tires inflated to the correct pressure. Low tire pressure makes the car work harder, which hurts gas mileage. This is especially important for a performance car like the C43.

Reduce any extra weight in the car. Take out anything from the trunk that you don’t need. More weight lowers gas mileage, mostly in city driving. The C43 has to work that much harder to accelerate.
