V-Max is a term used to describe the maximum velocity (speed) of a vehicle. It is a specification that refers to the maximum speed of a vehicle in a given gear, such as first, second, or third gear. V-Max is usually determined by the engine's power output, the engine's torque, the car's weight, the car's aerodynamics, and the transmission's gearing. V-Max can be affected by modifications such as turbochargers, exhaust systems, and other engine modifications. V-Max is an important factor to consider when purchasing a car and is often used by car enthusiasts to compare vehicle performance.
