The gross vehicle weight (GVW) of your car is calculated by adding the standard curb weight of the vehicle to the manufacturer's predictions for luggage weight and passenger weight.
The GVW also includes an allowance for liquids like fuel and oil.
Because it is computed by estimating a variety of factors, the GVW provides only an estimate for the weight of your car.
While your car's GVW provides an estimate, it does not give you any information about the total weight capacity of your vehicle.
Because it is computed by estimating a variety of factors, the GVW provides only a ballpark figure for the weight of your car.
