23 MPG combined is what you can expect if you are considering the 2019 Mercedes-Benz AMG E53 4matic Plus Coupe. Thinking about that number too much, however, is to miss what this machine is about. This isn’t just a commuter car; the E53 Coupe is a stylish, performance-oriented grand tourer that delivers a thrilling driving experience, and its fuel consumption reflects that.

City and highway performance

The EPA estimates 21 MPG in the city and 28 MPG on the highway. The city figure shows the E53’s compromise. Stop-and-go traffic will quickly expose the limitations of its boosted 3.0-liter inline-six. Extended highway runs, however, allow the engine to perform well, taking advantage of the smooth-shifting 9-speed automatic transmission and the car’s aerodynamic efficiency at higher speeds. The highway rating is where the E53 shines, hinting at its long-distance cruising capabilities. This car is better at gobbling up miles on an open road than crawling through rush hour.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2019 AMG E53 Coupe. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Premium fuel is required, so that cost is included in the estimate. Drivers who drive significantly more or less than 15,000 miles annually, or who encounter considerably higher fuel prices in their region, can expect their actual fuel costs to vary.

Real-world expectations

Getting the EPA’s 23 MPG combined rating in the real world requires restraint most E53 owners will find difficult. It’s hard to resist using the 429 horsepower and the quick torque provided by the electric auxiliary compressor. If driven hard, which is how to drive an AMG, fuel economy will likely fall into the high teens. If driven using fuel-saving techniques, you might see numbers in the low 30s on a long highway trip. Consider the EPA rating a best-case scenario under ideal conditions. See all Mercedes Benz fuel economy data here.

How it compares

The AMG E53 Coupe exists in a small segment. Competitors like the BMW M440i xDrive Coupe offer similar performance and luxury, and slightly better fuel economy, with an EPA combined rating of 25 MPG. The Audi S5 Coupe is another contender, delivering a combined 24 MPG from its turbocharged V6 engine. The E53 prioritizes a luxurious experience over the BMW, and has more distinctive styling than the understated Audi. Buyers considering the E53 are often less concerned with squeezing every last mile from a gallon of fuel and more interested in the blend of style, performance, and brand prestige.

Tips to maximize efficiency

Use the “Comfort” driving mode whenever possible. The E53’s Dynamic Select system allows you to set the car’s performance to your driving style and conditions. “Comfort” mode softens the throttle response, optimizes shift points for efficiency, and encourages relaxed driving, which translates to better fuel economy. When on the open road, turn on the adaptive cruise control. This system maintains a set speed and following distance, reducing the need for acceleration and braking, which consume extra fuel.

Make sure your tires are properly inflated and aligned. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Regularly checking and maintaining the recommended tire pressure (found on the driver’s side door jamb) can make a difference in fuel economy and also improves tire life. A misaligned suspension can also increase rolling resistance and reduce fuel efficiency.

Avoid idling for too long. Modern engines are designed to be more efficient when running than when idling. If you’re going to be stationary for more than a minute or two, it’s more fuel-efficient to turn off the engine. Restarting the engine consumes a small amount of fuel, but it’s less than the amount consumed by idling for a longer time. This is especially true for a boosted engine like the E53’s.

Resist accelerating aggressively all the time. The E53’s strong engine and quick torque delivery can be tempting, but frequent bursts of acceleration will quickly deplete your fuel tank. Gradual acceleration optimizes fuel consumption. Modulate the throttle and anticipate traffic flow to help you drive smoothly and consciously to return better MPG.
