* Vehicle type: Hybrids and electric vehicles generally have the highest MPG equivalent (MPGe for electric vehicles), but their initial cost is higher. Small, lightweight gasoline cars also tend to have high MPG.
* Driving style: Aggressive driving significantly reduces fuel efficiency in any vehicle.
* Year of manufacture: Fuel efficiency standards have improved over time, so newer vehicles generally offer better MPG than older ones.
* Specific model: Even within a vehicle class, different models and trims will vary in fuel economy.
That said, some vehicles consistently rank near the top in terms of MPG. Models from manufacturers like Toyota (Prius Prime, Corolla Hybrid), Honda (Insight, Civic Hybrid), Hyundai (Ioniq Hybrid, Kona Electric), and Kia ( Niro Hybrid, Niro EV) frequently appear on lists of the most fuel-efficient vehicles. However, you'll need to consult current EPA fuel economy estimates (available on fueleconomy.gov in the US) for the most up-to-date and accurate information on specific models and years.
