2024 Mercedes-Benz E350 4matic Fuel Economy: What to Expect

27 MPG combined is a respectable figure for the 2024 Mercedes-Benz E350 4matic, a vehicle designed for a refined driving experience rather than extremely thrifty gas mileage. This isn’t a compact economy car; it’s a mid-size luxury sedan with technology, comfort features, and an all-wheel-drive system. Its buyers want a smooth ride, a prestigious brand, and advanced features over saving every mile per gallon. They understand that they’re paying extra for the overall experience, and fuel economy is less important than someone shopping for a Prius.

City and highway performance

The EPA estimates the E350 4matic achieves 24 MPG in the city and 33 MPG on the highway. The city rating reflects urban driving, where the 2.0L turbocharged engine works harder and the all-wheel-drive system engages more frequently. The highway figure demonstrates the efficiency potential when cruising at a steady speed. The nine-speed automatic transmission helps, allowing the engine to operate at lower RPMs and reduce fuel consumption on long trips. Those who drive mostly on highways should see numbers close to, or even exceeding, the EPA estimate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Mercedes-Benz E350 4matic at $2,150. This is based on driving 15,000 miles per year and using national average fuel prices. It’s important to remember that this is an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. If you live in an area with higher than average gas costs or tend to drive more aggressively, you can expect to exceed the $2,150 estimate. However, careful drivers who mostly use the highway and take advantage of efficiency features may spend less.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Expectations should be within a few MPG of the EPA estimates under normal driving conditions. Observe the onboard computer while driving to instantly track MPG, or use a smartphone app to monitor fuel consumption over a longer period of time. The E350’s efficient engine and smooth transmission are helpful, but driving style is also important. A lead foot will quickly reduce fuel economy. Frequent use of the car’s many electronic features, especially the climate control system, can also impact fuel consumption.

How it compares

The E350 4matic’s fuel economy is competitive among mid-size luxury sedans. The BMW 530i xDrive, also with a 2.0L turbocharged engine and all-wheel drive, achieves approximately 27 MPG combined, putting it roughly on par with the E350. The Audi A6 45 TFSI quattro, another all-wheel-drive competitor, also achieves around 26 MPG combined. However, some competitors offer significantly better fuel economy with hybrid powertrains. For example, the Lexus ES 300h boasts around 44 MPG combined. For buyers focused on maximum efficiency, the Lexus is an alternative. However, these vehicles often have different priorities than buyers of a Mercedes-Benz. The E350 4matic’s fuel economy is what one would expect for a traditional luxury sedan. Before making a decision, consult all Mercedes Benz fuel economy data to consider the full range of options from the brand. Also, consider E350 MPG across all years to see trends.

Tips to maximize efficiency

Drive smoothly and consistently. Avoid sudden acceleration and braking, as these actions consume more fuel. Anticipate traffic flow and maintain a safe following distance to minimize the need for abrupt changes in speed. The E350’s adaptive cruise control system can help on long highway drives by maintaining a constant speed and reducing fuel consumption.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and inflate them to the recommended levels indicated on the doorjamb sticker. Properly inflated tires also improve handling and extend tire life. Routine maintenance is also very critical to any vehicle obtaining maximum fuel economy.

Use the car’s driving modes. The E350 4matic offers various driving modes, including an “Eco” mode that optimizes engine and transmission settings for fuel efficiency. This mode can help improve your MPG, particularly in city driving. These modes typically alter throttle response and transmission shifting speed.

Use accessories, especially air conditioning, sparingly. The air conditioning system places a load on the engine, increasing fuel consumption, so open the windows or use the ventilation system on cooler days. The difference between using only the fan and running the A/C can be substantial over time.

Reduce weight. Extra weight in the vehicle reduces fuel economy. Remove any unnecessary items from the trunk and back seat, since every extra pound contributes to increased fuel consumption, especially during acceleration. A full trunk of cargo can significantly impede MPG, especially during short urban trips when the car never has the chance to reach efficient cruising speeds.
