Fuel economy refers to the distance a vehicle can travel per unit of fuel consumed, typically measured in miles per gallon (MPG) or liters per 100 kilometers (L/100km). It is a crucial factor for consumers when purchasing vehicles, as it directly impacts operating costs and environmental sustainability. Higher fuel economy means less fuel is needed for travel, which can lead to significant savings over time. Improving fuel economy can be achieved through various means, including adopting more efficient driving habits, maintaining vehicles properly, and choosing vehicles designed for better efficiency. Additionally, advancements in technology, such as hybrid and electric vehicles, are reshaping the landscape of fuel economy, offering alternatives that reduce reliance on traditional fossil fuels.
