Polttoainetaloudellisuudesta
Polttoainetaloudellisuudesta, commonly known in English as fuel economy, refers to the efficiency with which an engine uses fuel to perform work. The concept measures the distance a vehicle can travel per unit of fuel, typically expressed as kilometers per liter or miles per gallon. It is a critical parameter for consumers, policymakers, and manufacturers, influencing purchasing decisions, environmental policies, and technological development. Fuel economy is determined by factors such as engine design, vehicle weight, aerodynamics, transmission efficiency, and drive‑cycle characteristics.
The European Union regulates fuel economy through the Ecodesign Directive and the Motor Vehicle (Fuel Consumption)
Improving polttoainetaloudellisuudesta has direct economic benefits for drivers, lowering fuel costs over the lifespan of a
