Curb weight (US English) or kerb weight (UK English) or unladen mass is the total weight of a vehicle with standard equipment, all necessary operating consumables (e.g., motor oil and coolant), a full tank of fuel, while not loaded with either passengers or cargo.
This definition may differ from definitions used by European Union manufacturers include the weight of a 75 kilogram driver to follow European Directive 95/48/EC. Additionally, organizations may define curb weight with fixed levels of fuel and other variables to equalize the value for the comparison of different vehicles.
