If you’re considering the 2020 Mercedes-Benz GLE580 4matic, the combined fuel economy is 19 MPG. It’s a mid-size luxury SUV with a strong 4.0-liter V8, designed for easy cruising and confident towing, while prioritizing luxury and technology. Buyers are likely more focused on performance and prestige than maximizing fuel efficiency.

City and highway performance

The EPA estimates 17 MPG in the city and 21 MPG on the highway. These numbers reflect the large engine and the vehicle’s heavy weight. City driving increases fuel consumption as the engine works harder to accelerate from a stop. The highway MPG is better because the engine operates more efficiently, and the nine-speed automatic transmission helps to optimize fuel use at higher speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Mercedes-Benz GLE580 4matic at $3,050. This is based on driving 15,000 miles per year and using average national fuel prices. Your fuel costs will change based on your driving habits, the roads you drive on, and fuel price changes. This $3,050 figure is a standard for comparison.

Real-world expectations

EPA numbers are a guide, but real-world MPG changes based on driving style, load, and terrain. Hard acceleration, frequent hard braking, and heavy loads will all decrease fuel economy. Driving gently and anticipating traffic can improve your mileage. The GLE580’s turbocharged engine with electric motor helps reduce inefficiencies, but the driver is important for achieving good fuel consumption.

How it compares

The GLE580’s MPG is similar to other V8-powered competitors. The BMW X5 M50i also gets around 19 MPG combined. The Audi SQ7, with similar performance and luxury, has comparable numbers. Six-cylinder configurations offer slightly better economy. For example, the Volvo XC90 T6 gets around 23 MPG combined. If saving fuel is your top priority, consider the Lexus RX 450h hybrid, which gets significantly better MPG. But that means sacrificing V8 power and the GLE580’s luxury and performance.

Tips to maximize efficiency

Use the GLE580’s driving modes. Select “Comfort” or “Eco” mode for everyday driving to optimize throttle response and shift points for fuel efficiency. Avoid using the V8’s full power unless needed. Smooth acceleration and a consistent speed improve fuel mileage.

Make sure your tires are properly inflated. Under-inflated tires increase rolling resistance, making the engine work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the pressure listed on the driver’s side door jamb.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern vehicles restart quickly, and idling wastes fuel, especially with the GLE580’s V8.

Reduce weight. Remove unnecessary items from the vehicle, because extra weight reduces fuel economy. Transporting items you don’t need puts extra strain on the engine, especially when accelerating.

Plan your routes well. Avoid peak traffic and choose routes with fewer stops. Frequent acceleration and braking use more fuel than maintaining a steady speed, so minimizing these instances can save gas.
