19 MPG combined is what you can expect from a high-performance SUV like the 2023 Mercedes-Benz AMG GLE53 4matic Plus. Buyers of this vehicle aren’t prioritizing fuel efficiency like a Prius; they want thrilling acceleration, a luxurious interior, and the Mercedes-Benz emblem. Fuel economy is secondary, but it matters to ownership costs. The GLE53 focuses on performance and then considers gasoline consumption.

City and highway performance

The city and highway MPG difference shows more about the GLE53’s fuel consumption. The EPA estimates 18 MPG in the city and 22 MPG on the highway. The lower city MPG isn’t surprising because of frequent stops and starts, plus the AMG engine’s ability to deliver power instantly. Highway driving, with more consistent speeds, allows the 48-volt mild-hybrid system to save more fuel. The system can shut off the engine in certain situations, like gliding at highway speed, which conserves fuel without losing the immediate power AMG buyers expect.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz AMG GLE53 4matic Plus at $3,050. This is based on driving 15,000 miles per year and national average fuel prices. Your fuel costs could be higher or lower depending on your driving, the type of driving you do (city or highway), and local fuel prices. The AMG GLE53 also requires premium fuel, increasing running costs. This annual fuel cost is a large expense, but most GLE53 buyers have likely considered it.

Real-world expectations

The EPA provides a standard estimate, but real-world fuel economy varies. Drivers who accelerate quickly will likely see numbers below the official ratings, especially during fast driving or short trips. Conversely, drivers who accelerate smoothly and anticipate traffic might match or exceed the EPA figures, especially on long highway drives.

The car’s driving modes affect fuel consumption. Choosing “Comfort” mode instead of “Sport” or “Sport+” will reduce the engine’s responsiveness and improve efficiency. However, resisting the urge to fully unleash the AMG’s performance will be the biggest challenge for most owners. If you want to see the AMG MPG across all years, we have this data.

How it compares

The AMG GLE53 is in the high-performance SUV segment along with others. The BMW X5 M50i offers similar performance but a slightly better EPA combined rating of 20 MPG. The Porsche Cayenne S achieves 19 MPG combined, the same as the GLE53.

These differences may seem small, but they can add up. Buyers often compare performance, luxury, and fuel efficiency. For some, the AMG brand’s prestige and driving are worth a slight MPG decrease. Others may sacrifice performance for better efficiency from the BMW or Porsche. For reference, you can view all Mercedes Benz fuel economy data here.

Tips to maximize efficiency

Select “Comfort” mode to soften throttle response and optimize shift points for fuel efficiency. This is useful in stop-and-go traffic.

Use cruise control on the highway. Maintaining consistent speed improves fuel economy and reduces driver fatigue on long trips. Be mindful of hills to minimize acceleration and deceleration.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure and inflate them to the recommended level, found on the driver’s side doorjamb.

Reduce unnecessary weight. Excess cargo strains the engine, increasing fuel consumption. Remove unnecessary items, especially heavy objects, from your car.
