Is an average fuel consumption of 7.8 high?

[MacRose]

An average fuel consumption of 7.8 is not high. Most models on the market have a fuel consumption level between 7 and 8. Transmission affects fuel consumption: The transmission is a power-speed adjustment device connected between the engine output and the wheel drive shaft. Its basic functions are: changing the corresponding "power-speed" combination according to the driving needs of the car, changing the speed direction (reverse gear), and separating the connection between the engine and the drive shaft (idle speed). Design factors affect fuel consumption: This mainly refers to the drag coefficient. Body design is not only for aesthetics but also considers the drag coefficient. The more streamlined and smoother the car is designed, and the smaller the body attachments, the more effectively the drag can be reduced. The lower the drag coefficient, the lower the vehicle's drag, the better the stability, and the more fuel-efficient it is. Generally, for every 10% decrease in drag coefficient, fuel consumption can be reduced by 3%.
