Weight: The weight affects fuel efficiency, and the Mercedes-Benz E-Class is no exception. While the car is designed to balance luxury features, added unnecessary cargo cuts down the mileage. Even a roof rack or extra weight in the trunk can cause additional drag. Therefore, minimising extra load, especially on long trips, will help prevent increased fuel consumption.
Traffic and Route Conditions: The mileage your Mercedes-Benz E-Class will provide depends greatly on the conditions of traffic and routes. Drives in the city with frequent halts can greatly reduce mileage, while highway driving offers better fuel economy. With real-time traffic updates, the navigation system can help avoid entering congested areas and routes that are smoother to help you save fuel.
Driving Mode: People who own the Mercedes-Benz E-Class appreciate the comfort and driving dynamics of the Comfort, Sport, and Sport+ modes. Although convenient, these modes sacrifice fuel efficiency with high-quality performance. They might tighten the throttle response and delay gear shifts, meaning more fuel is consumed because the engine revs higher than necessary. Comfort mode is less aggressive, yet it does not optimise fuel economy as it does in ECO mode.
Fuel Quality: The type of fuel you use in the Mercedes-Benz E-Class will influence its mileage. Always choose top-of-the-line fuel, as the lesser variants will decrease your engine efficiency and impact your mileage. You could use regular gasoline to save a little money, but it will shave off your mileage in the long run and potentially ruin the engine. Always stick with the manufacturer's recommended fuel for optimal performance.
