What is the optimal combination of vehicle weight and horsepower?

[OPhoebe]

Generally, the power matching standard for civilian passenger cars is around 100KW corresponding to a vehicle weight of 1450kg-1550kg, which is about 1.5 tons. This value can meet the power demand. If the weight is less than this value, it usually means the car is underpowered; if it's more, it indicates power reserve. Here are some introductions about vehicle weight: 1. Introduction one: Heavy-duty vehicles generally refer to heavy-duty trucks, which are M-class and N-class vehicles with a maximum total mass greater than 3500Kg. 2. Introduction two: This type of vehicle consists of a heavy-duty tractor and a heavy-duty trailer forming a vehicle train. They usually adopt multi-axle tandem hydraulic suspension devices and are generally used for transporting large cargoes whose size and weight exceed the limits set by road traffic regulations.
