When shopping for a new car, fuel efficiency is one of the most important factors for many buyers. The good news is that most modern vehicles are far more efficient than older models, and some are better than others. The Environmental Protection Agency (EPA) rates the fuel economy of new vehicles so consumers can make an educated decision. In addition, the Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule, issued by the National Highway Traffic Safety Administration (NHTSA) and EPA, sets stringent fuel economy and carbon dioxide standards that increase 1.5% per year from 2021 to 2026 for both passenger cars and light trucks. This means that car buyers have a wide range of options when it comes to choosing a vehicle that is both fuel-efficient and safe.

Electric vehicles
The high efficiency of electric-drive components in EVs results in lower fuel costs and reduced emissions. All-electric vehicles produce zero tailpipe emissions, and plug-in hybrid electric vehicles (PHEVs) emit nothing when operating in all-electric mode. The use of electricity as a power source for transportation improves public health and the environment, and provides safety benefits. EVs also have performance benefits, with electric motors providing quiet, smooth operation and stronger acceleration, requiring less maintenance than internal combustion engines.
EVs have a shorter driving range than most conventional vehicles, although this is improving. Most EVs can travel more than 100 miles on a single charge, and some can exceed 200 or 300 miles, depending on the model. The battery charging efficiency of EVs can vary but is often between 84% and 93%.
The purchase price of EVs can be significantly higher than that of conventional vehicles, but this is likely to change as production volumes increase and battery technologies mature. These initial costs can be offset by fuel cost savings, federal tax credits, and state and utility incentives.

Hybrid vehicles
Hybrids are more efficient in city driving because they reduce idling by turning the engine off when the vehicle comes to a stop and restarting when the accelerator is pressed. This, along with regenerative braking, makes hybrids more efficient than conventional vehicles in city driving, which includes a significant amount of idling. The Toyota Prius, for example, is known for its reliability and offers an overall fuel economy of 43 mpg. The 2024 Toyota Camry Hybrid is another excellent choice, offering reliability and fuel economy in a midsize sedan package.
The Kia Niro is another practical and efficient hybrid SUV with advanced technology and an impressive warranty. The Hyundai Elantra Hybrid is also a good option, offering 51/58/54 mpg, while the Toyota Corolla Hybrid provides 53/46/50 mpg. The 2024 Honda Civic is another fuel-efficient option, with the most efficient model being the mid-level EX, rated at 33/42/36 mpg.
While hybrids have improved significantly over the years, drawbacks such as slower acceleration and higher costs compared to conventional vehicles may still be present. However, with advancements in technology, these issues are being addressed, making hybrids a more attractive option for those seeking fuel efficiency and safety.
