What is the fuel consumption of the Murano Hybrid?

The official combined fuel consumption of the Murano Hybrid is 8.6L/100km. Here are some factors that can increase fuel consumption: Road conditions: Poor road conditions or uneven surfaces that require the vehicle to operate in lower gears for extended periods will inevitably increase fuel consumption. Incorrect driving habits: Improper driving habits have the greatest impact on fuel consumption. Actions such as slamming on the brakes, inconsistent speeds, prolonged engine idling, aggressive acceleration, and driving at high speeds in low gear over long distances can all lead to increased fuel consumption. Prolonged idling: Compared to normal driving, the engine ECU controls a higher fuel injection rate when the car is idling or just started. If the engine is not turned off or frequently idles for extended periods, fuel consumption will increase.

Why is the Outlander engine noisy?

The reasons for the loud engine noise in the Outlander are as follows: Engine produces a "popping" sound: The unpleasant engine noise is most likely caused by the engine being either overheated or too cold, and there is also a high probability of insufficient oil. Engine overheating leading to loss of power: If the engine operates for an extended period, causing the surface to overheat, the cooling system may fail. The first step in this situation is to check the cooling system. If there is an issue with the cooling system, it could lead to exhaust blockage, as the vacuum tube might be broken. At this point, steam or hot air may escape from the engine, producing a "hissing" sound.
