What is the fuel consumption per 100 kilometers for a Mercedes-Benz SUV?

Mercedes-Benz SUV consumes around 6L per 100 kilometers. Method for calculating actual fuel consumption: Fuel consumed/distance traveled = fuel consumption per kilometer (usually measured per 100 kilometers, then multiplied by 100). To calculate, fill up the car's fuel tank completely and reset the odometer to zero. After driving for a period, refill the tank and note the amount of fuel added. Divide the fuel added by the distance traveled to get the fuel consumption per kilometer. If the distance is measured in 100 kilometers, the result is the fuel consumption per 100 kilometers. Fuel-saving tips: Rapid acceleration and sudden braking waste a lot of fuel, so avoid them.

Generally, if the electric vehicle's battery has been used for more than three years, water loss faults often occur.
