Consuming 8 liters per 100 kilometers is generally considered a normal level. However, this depends on the vehicle model, engine displacement, and engine system, as well as the driving conditions. For micro or compact cars, 8 liters would be considered relatively high fuel consumption. For family sedans, this is within the normal range. For mid-sized cars, 8 liters per 100 kilometers would be considered very low fuel consumption. Here is some relevant information: 1. Factors affecting fuel consumption: Generally, the larger the engine displacement, the higher the fuel consumption. However, there is no direct conversion formula between the two, as many factors influence fuel consumption. These include not only the engine's powertrain but also the transmission, drag coefficient, vehicle weight, and tires. Driving habits, vehicle condition, and road conditions also play significant roles. 2. Key technologies related to fuel consumption: (1) Reducing vehicle weight: Vehicle weight and fuel consumption are directly proportional. It is said that a 10% reduction in vehicle weight can lead to a corresponding reduction in fuel consumption by several percentage points. (2) Improving vehicle aerodynamics: A lower drag coefficient can significantly reduce fuel consumption. These two factors are also directly proportional. (3) Maximizing engine thermal efficiency: The thermal efficiency of a typical gasoline engine (the proportion of fuel converted into useful work) is around 30%, while diesel engines exceed 40%. This is the main reason why diesel engines are more fuel-efficient than gasoline engines.
