Fuel efficiency refers to the measure of how effectively a vehicle converts fuel into energy for motion. It is typically expressed as miles per gallon (MPG) or liters per 100 kilometers (L/100 km) and indicates how far a vehicle can travel on a specific amount of fuel. Higher fuel efficiency means that a vehicle can travel further on less fuel, resulting in reduced fuel costs and lower emissions of greenhouse gases and pollutants.
