Curb Weight vs Gross Weight: What’s The Difference?

You might be wondering that your car or truck comes with two different weight measurements. They are curb weight and gross weight. But, many vehicle owners do not know the actual meaning of those.

You should know about those weights and what the difference is between them. For example, there is a maximum weight limit if you want to cross a bridge.

If you know which weight class your car falls in, then you can easily know whether you can cross the bridge or not.

What is The Curb weight?

The curb weight determines the vehicle’s actual weight, including all standard equipment such as fuel tank, fuel coolant, transmission fluid, motor oil, brake fluid, and other fluids. You should cut out the optional equipment, passengers, and cargo weight when measuring the curb weight. 

It is also known as a “standard weight.” Sometimes, the curb weight varies from manufacturer to manufacturer, even model to model but slightly. For example, some European manufacturers also include the driver weight in the curb weight measurement. 

Curb weight includes:

  • Factory Installed equipment
  • Engine oil weight
  • Transmission oil weight
  • Gearbox oil weight
  • Coolant oil weight
  • Ac refrigerant weight
  • 90% fuel weight

Note: It may differ from country to country.

What is the Gross Weight?

The gross weight or GVWR means your vehicle’s passengers, cargo, and other optional equipment, including the curb weight. It will help you to know how much extra weight is safer for you. For example, if you own a truck whose curb weight is 6,000 pounds and your GVWR is 7,500 pounds, you can carry around 1,500 pounds in your truck.

What is the Difference Between Curb Weight and Gross Weight?
