The reasons for the loud engine noise in the new Mondeo: Insufficient tire inflation: If you notice that the vehicle's coasting distance is significantly reduced during driving, you should check whether the tire pressure meets the standard. Insufficient tire inflation will also increase fuel consumption. Severe tire wear: Check the degree of tire wear. If the tires are severely worn, slipping will frequently occur, increasing fuel consumption. Abnormal wheel rotation: If you notice abnormal noise from the wheels during driving or starting, promptly check for faults in the bearings and braking system. Abnormal wheel rotation will affect speed and increase fuel consumption.
I also experienced increased engine noise with my new Mondeo, possibly due to internal engine wear such as enlarged piston ring or bearing clearances causing louder friction sounds. Poor fuel quality or aged engine oil can lead to insufficient lubrication, making the noise more noticeable. Exhaust system leaks or damage may also cause abnormal sounds. If the engine mounts are worn out, vibrations transmitted upwards can amplify the noise. It's advisable to promptly visit a 4S shop for inspection—a minor maintenance service might resolve the issue. Don't delay until it becomes a safety concern, and you could save on fuel costs by avoiding waste.
