Toyota is widely recognized as the most fuel-efficient car brand in the United States. This reputation is supported by various factors, including the brand's commitment to hybrid technology and its extensive range of fuel-efficient models. According to the U.S. Environmental Protection Agency (EPA), Toyota vehicles consistently rank among the top in fuel economy. For instance, the Toyota Prius, a hybrid vehicle, has been a leader in fuel efficiency for years, achieving up to 56 miles per gallon (mpg) in the city and 50 mpg on the highway. Additionally, the Toyota Corolla, another popular model, offers an impressive 35 mpg combined. These figures are significantly higher than the average fuel economy of new vehicles in the U.S., which was around 25 mpg in 2021. Toyota's focus on efficiency and its extensive research and development in this area have contributed to its dominance in fuel economy.
