Fuel efficiency and performance

Fuel efficiency is a critical aspect of modern vehicles, and it refers to the ratio of effort to result in converting the chemical energy in fuel into the kinetic energy that propels a vehicle forward. The performance of a vehicle is more accurately measured by fuel consumption, which indicates a linear relationship, whereas fuel economy can lead to distortions in efficiency improvements.

Several factors influence a vehicle's fuel efficiency, including engine parameters, aerodynamic drag, weight, air conditioning usage, and rolling resistance. Additionally, driver behaviour can significantly impact fuel economy. For example, aggressive driving habits such as sudden acceleration and heavy braking waste energy and reduce fuel efficiency. On the other hand, energy-efficient driving techniques, such as maintaining steady speeds and avoiding excessive idling, can help maximise fuel efficiency.

To improve fuel efficiency, automotive manufacturers are exploring various strategies, including alternative fuel sources, engine improvements, and weight reduction. For instance, the use of liquefied petroleum gas, ethanol, and natural gas can reduce oil dependency. Additionally, advancements in combustion engine technology aim to enhance engine efficiency and minimise emissions. The adoption of lightweight materials, such as aluminium, carbon fibre, and high-strength steel, also plays a crucial role in improving fuel efficiency by reducing vehicle weight.

Safety and fuel efficiency improvements do not drive up the cost of cars. A Consumer Reports analysis of car prices going back nearly two decades found that vehicle prices did not increase during the time period studied (model years 2003 through 2021) even as average fuel economy increased by 30% and proven lifesaving safety technologies became common features. During the period studied, electronic stability control and backup cameras became required on all new cars, and advanced driver assistance systems became widely available.

The Trump administration has argued that higher fuel efficiency standards would force automakers to build lighter cars, which they say would be less safe in the event of a crash. However, critics say that recent gains in safety technology and fuel economy show that lighter cars are not necessarily less safe. The Alliance of Automobile Manufacturers supports continued improvements in efficiency as well as incentives for specific new fuel-saving technologies while balancing priorities like affordability, safety, jobs, and the environment. Freezing fuel-economy standards could cause an additional 2.2 billion tons of car emissions to be released into the Earth's atmosphere by 2040, according to the Union of Concerned Scientists.
