The horsepower of a semi-trailer typically ranges from 300 to 600 horsepower, depending on the model, intended use, and configuration. Horsepower is an important indicator of engine power, directly affecting the vehicle's traction and driving performance. For long-distance transport or heavy-load needs, it is recommended to choose a model with higher horsepower (such as 450 horsepower or more) to ensure sufficient power and fuel efficiency. For short-distance or light-load transport, a model with 300-400 horsepower can be chosen to reduce costs. In addition, horsepower selection should also consider factors such as road conditions, load capacity, and driving habits.
