The 2024 Mercedes-AMG C43 4MATIC gets 23 MPG combined. While not terrible for a performance sedan with all-wheel drive, it’s not particularly fuel-efficient. This figure is a compromise, a blend of exciting driving and some consideration for fuel costs. C43 buyers aren’t focused on efficiency, but they probably appreciate that it doesn’t burn gas excessively.

City and highway performance

The EPA estimates the 2024 AMG C43 at 20 MPG in the city and 28 MPG on the highway. This difference shows the C43’s character. In the city, stop-and-go traffic reduces the benefits of the 2.0L turbocharged engine’s efficiency features, and the engine’s boost encourages more aggressive driving, which increases fuel use. On the open road, where the car can cruise comfortably and the nine-speed automatic transmission can operate efficiently, the C43 performs better. The highway MPG is respectable, meaning longer trips won’t be too expensive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-AMG C43 4MATIC at $2,500. This is based on driving 15,000 miles per year and the EPA’s fuel price projections. Note that this is just an average. Your actual fuel costs will vary based on your driving habits, fuel type, and local gas prices. Someone who often uses launch control and only uses premium fuel in California will probably spend much more.

Real-world expectations

EPA figures are a useful benchmark, but real-world fuel economy often differs. Aggressive driving, short trips, and cold weather can all hurt the C43’s MPG. However, a driver who accelerates smoothly, anticipates traffic, and mainly drives on the highway might see figures close to or even above the EPA estimates. The AMG C43’s turbocharged engine reacts to driving style: careful throttle inputs result in better mileage. Expect more frequent gas station trips if you’re always using the boost.

How it compares

The AMG C43’s fuel economy is similar to its rivals but not the best in its class. The BMW M340i xDrive, achieves an EPA-estimated 26 MPG combined, a noticeable improvement. The Audi S4 gets about 24 MPG combined. While these competitors are more efficient, the C43 stands out with its AMG-tuned powertrain and focused driving experience. For many buyers, that makes up for the slightly lower MPG. Looking at AMG MPG across all years, the current C43 is more efficient than older AMG models with larger engines.

The C43 values performance over maximizing fuel savings, a trade-off its buyers generally accept.

Tips to maximize efficiency

The AMG C43 is designed for performance, but you can still improve its fuel economy without losing all the fun. Avoid constantly accelerating hard. Smooth and progressive throttle inputs will allow the turbocharger to operate efficiently and reduce fuel consumption.

Use the car’s driving modes carefully. “Comfort” or “Eco” modes change the throttle response and shift points to prioritize less gas. These modes might reduce the AMG driving experience, they can make a noticeable difference when commuting.

Make sure your tires are inflated properly. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and inflate them to the recommended levels, which you can find on the door jamb or in the owner’s manual.

Remove any unnecessary weight from the car. Take out items from the trunk or passenger area that aren’t needed. Extra weight increases the engine’s workload, leading to higher fuel use. A lighter car also responds better, so this is a benefit.

Plan your routes strategically. Avoid areas with heavy traffic or frequent stops. Choosing routes with less traffic and consistent speeds will help maintain better fuel economy.
