0–60 mph (0–100 km/h) measures how quickly a vehicle accelerates from a complete stop to a common real-world speed. It is expressed in seconds — the lower the number, the faster the acceleration. This metric gives a quick idea of a vehicle’s performance and is influenced by engine power, torque, weight, traction, and drivetrain layout. While widely used for comparison, real-world results can vary depending on conditions and driving technique.
