What Is the Difference Between a Truck and a Semi Truck?

The terms ‘truck’ and ‘semi-truck’ are often used interchangeably, but they are two distinct types of vehicles. While both trucks and semi-trucks are heavy-duty vehicles used to transport large loads, there are several differences between them.

Size and Weight

Trucks typically weigh between 3,000 and 4,500 pounds, while semi-trucks can weigh up to 80,000 pounds. This is due to the fact that while trucks are designed to transport goods and materials over relatively short distances, semi-trucks are intended for hauling larger loads over greater distances. Semi-trucks have an additional trailer attached to the main cabin that can be up to 53 feet long.

Cab Design

The cab of a truck is typically a single unit with seating for two people. Semi-trucks have a separate cab and trailer connected by a fifth wheel hitch. The cab of a semi-truck can be either a single unit or double unit, with sleeping quarters in the back for long hauls.

Engine Power

Trucks have smaller engines than semi-trucks. While trucks have engines that range from four to eight cylinders with up to 400 horsepower, semi-trucks have engines with up to 18 cylinders with 1,800 horsepower.

Fuel Efficiency

Since they have larger engines, semi-trucks are much less fuel efficient than trucks. Semi-trucks can get as little as 5 miles per gallon of fuel compared to the 20 miles per gallon that some trucks can achieve.

In conclusion, there are several key differences between trucks and semi-trucks including their size and weight, cab design, engine power, and fuel efficiency. Trucks tend to be smaller with fewer cylinders in their engine and better fuel economy whereas semi-trucks tend to be bigger with more powerful engines but lower fuel efficiency.
