Polttoainetalous, also known as fuel economy, refers to the efficiency with which a vehicle uses fuel to travel a certain distance. It is typically measured in miles per gallon (MPG) in the United States and kilometers per liter (km/L) in many other parts of the world. Higher fuel economy values indicate a more efficient vehicle, meaning it consumes less fuel to cover the same distance.

Factors influencing a vehicle's fuel economy are numerous. These include the engine's size and design, vehicle weight, aerodynamic drag, tire pressure, driving habits, and the type of fuel used. For instance, larger, heavier vehicles with less aerodynamic shapes generally have lower fuel economy. Aggressive driving, such as rapid acceleration and hard braking, also significantly reduces efficiency.

Improving fuel economy has several benefits. Primarily, it leads to lower fuel costs for consumers, reducing their overall transportation expenses. Environmentally, better fuel economy means less fuel is burned, resulting in reduced emissions of greenhouse gases and other pollutants, contributing to cleaner air and mitigating climate change.

Automakers strive to improve fuel economy through various technological advancements. These include more efficient engine designs, hybrid powertrains that combine gasoline engines with electric motors, lightweight materials in vehicle construction, and aerodynamic enhancements. Government regulations and consumer demand also play a crucial role in driving the development and adoption of more fuel-efficient vehicles. Understanding and prioritizing fuel economy is therefore important for both economic and environmental reasons.
