24 MPG combined isn’t going to win any fuel economy awards, but for the 2020 Mercedes-Benz AMG E53 4matic Plus, it’s an acceptable trade-off for exciting performance and undeniable luxury. This isn’t a car bought by penny-pinchers. It’s for those who value a potent blend of power, comfort, and advanced technology, accepting the fuel bill as part of ownership.

City and highway performance

The EPA estimates the AMG E53 at 21 MPG in the city and 28 MPG on the highway. The city figure reflects urban driving’s stop-and-go nature, where the E53’s mild-hybrid system works to provide smooth start-stop functionality and electric assist to the turbocharged inline-six. The highway number, while better, indicates the E53’s performance. Even at cruising speeds, the 9-speed automatic transmission is always ready to downshift and unleash the engine’s reserves of power for easy passing.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 Mercedes-Benz AMG E53 is $2,400. This calculation is based on driving 15,000 miles per year and using average national fuel prices for premium gasoline, required for best engine performance. Individual driving habits and local fuel costs can affect fuel spending. Drivers with a heavier foot, or those in areas with higher gas prices, may exceed this estimate. More conservative drivers could see a lower yearly fuel spending.

Real-world expectations

EPA estimates provide a useful benchmark, but real-world fuel economy often varies. AMG E53 owners who frequently push the car’s performance will likely see figures closer to the city rating, or even lower. Those who primarily use the vehicle for longer trips and prioritize smooth acceleration can expect to achieve numbers closer to, or even above, the 28 MPG highway estimate. The E53’s advanced technology, including its AMG-tuned suspension and performance-oriented drivetrain, encourage a driving style that isn’t always best for fuel efficiency.

How it compares

Compared to direct competitors, the AMG E53’s fuel economy is reasonable. The BMW M550i xDrive, with its 4.4-liter V8, offers similar performance but typically returns around 20 MPG combined. The Audi S6, equipped with a turbo V6, also achieves figures in the low- to mid-20s. Some may consider alternatives with more focus on efficiency. For example, the Lexus GS 350 trades performance for a smoother ride and more predictable fuel economy around 24 MPG combined, but is not a direct competitor in terms of driving excitement. Buyers considering the AMG E53 often cross-shop it against these vehicles, weighing performance against running costs. You can find all Mercedes Benz fuel economy data on this site.

Tips to maximize efficiency

Carefully select the car’s driving modes. The “Comfort” mode helps fuel efficiency by optimizing throttle response, transmission behavior, and suspension. While not as engaging as the “Sport” or “Sport+” modes, it improves fuel economy during everyday driving without losing too much performance. Consider using this mode on highway stretches or in congested city traffic.

Check tire pressure regularly. Maintaining the recommended tire pressure, found on the door jamb sticker, minimizes rolling resistance and improves fuel economy. Underinflated tires create more friction, making the engine work harder. A tire pressure check can affect fuel efficiency.

Anticipate traffic and practice smooth acceleration and braking. Avoiding sudden acceleration and hard braking reduces fuel use. By anticipating traffic and maintaining a speed, you can minimize the need for dramatic acceleration and deceleration, which contribute to fuel inefficiency. The predictive cruise control can help.

Limit idling time. Idling burns fuel. If you expect to be stopped for more than a minute or two, turn off the engine. The AMG E53’s start-stop system helps with this in city driving, but manually switching off the engine can save more fuel. Remember that this particular model represents AMG MPG across all years, and there are tradeoffs.

Ensure regular maintenance per the manufacturer’s recommendations. A well-maintained engine runs more efficiently. Regular oil changes, air filter replacements, and spark plug maintenance optimize engine performance and fuel economy. Following the service schedule helps ensure the engine operates efficiently, using less gas.
