Curb weight
What the vehicle weighs empty, with all fluids but no passengers or cargo.
Curb weight is the vehicle's weight ready to drive but empty: full fluids and fuel, no passengers, no cargo. It is the baseline figure that towing, payload, and efficiency calculations build on.
Weight touches everything: a lighter car accelerates, stops, and corners more easily and burns less fuel. EVs run heavy because of their batteries, often 1,000 pounds more than a comparable gasoline car, which their instant torque masks well.
