2024 Mercedes-Benz GLE450 4matic Fuel Economy: What You Need to Know

The 2024 Mercedes-Benz GLE450 4matic gets 22 MPG combined, which isn’t going to win any efficiency awards, but it’s an acceptable compromise for buyers. People who want this mid-size luxury SUV usually care more about a smooth ride, advanced technology, and the Mercedes-Benz name than saving money on gas. This is a calculated choice.

City and highway performance

The EPA estimates the GLE450 will achieve 19 MPG in city driving and 26 MPG on the highway. This difference is due to the turbocharged 3.0-liter inline-six engine and 48-volt mild-hybrid system. In stop-and-go traffic, the GLE450’s weight and acceleration use more fuel. On the open road, the engine is more efficient, helped by the smooth nine-speed automatic transmission. The mild-hybrid system gives a small boost when accelerating and allows the engine to stop and start easily, helping fuel economy a bit in the city and on the highway.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz GLE450 4matic at $2,650. This is based on driving 15,000 miles per year and using premium gasoline, which is recommended. It’s an expense that buyers should consider. Fuel prices can change, so the actual amount spent could be different.

Real-world expectations

The EPA estimates are a starting point, but actual fuel economy changes with driving habits, terrain, and weather. If you accelerate quickly, drive short distances often, and carry heavy loads, fuel efficiency will go down. Consistent highway driving at moderate speeds can meet or slightly exceed the EPA’s highway rating. The GLE450’s 4MATIC all-wheel-drive system helps with traction, but uses slightly more fuel than a rear-wheel-drive car.

How it Compares

The GLE450’s fuel economy is similar to other luxury SUVs. The BMW X5 xDrive40i, with a similar inline-six engine, gets nearly the same EPA ratings. The Audi Q7 55 TFSI, with a turbocharged six-cylinder engine, also has similar numbers. However, a performance version like the Mercedes-AMG GLE53 uses more fuel. Some competitors have plug-in hybrid models, such as the BMW X5 xDrive50e, which has better fuel efficiency in the city with all-electric range before switching to hybrid for longer trips. The Land Rover Range Rover Sport offers similar luxury and off-road capability, but generally gets lower fuel economy than the GLE450. For GLE450 buyers, the choice is about luxury, performance, and technology and small fuel economy differences are frequently less important. Buyers shopping across the Mercedes Benz lineup should compare all Mercedes Benz fuel economy data to see which model fits their fuel needs.

Tips to Maximize Efficiency

Drive smoothly. Avoid fast acceleration and hard braking, which use more gas. Watch traffic and keep a steady speed. Use cruise control on the highway to keep your speed steady and save fuel.

Choose the GLE450’s driving modes. Select “Eco” mode to change the engine and transmission for better fuel efficiency. This might slightly reduce throttle response, but can save fuel, especially in the city.

Regular maintenance helps fuel economy. Keep tires inflated, as low tires increase rolling resistance and waste fuel. Keep the engine tuned and fix mechanical problems quickly.

Don’t idle. If you’ll be stopped for more than a minute, turn off the engine. Modern engines restart quickly, and idling wastes fuel and increases emissions.

Remove extra weight. Removing cargo can improve fuel economy, especially in the city. Every pound increases fuel use, so only carry what you need. Check out GLE450 MPG across all years for more information.
