In the context of constantly fluctuating and unpredictable fuel prices, fuel efficiency is becoming an increasingly important criterion when consumers choose to buy a car. Therefore, more and more buyers are tending to choose hybrid vehicles to save on fuel costs, but models equipped with pure gasoline engines still have advantages in terms of purchase price and initial investment costs.
However, non-hybrid models, using only pure gasoline engines, still have advantages in terms of price and initial investment costs. Notably, Japanese automakers are always excellent at building gasoline-powered vehicles with impressive fuel efficiency. Meanwhile, some German and South Korean automakers are also equally competitive.
According to data from the U.S. Environmental Protection Agency (EPA), the average fuel consumption of new cars in the U.S. in 2025 is 8.65 liters/100 km. However, some gasoline models have combined fuel consumption figures of only around 7.84 liters/100 km, and some even as low as 6.5 liters/100 km. Below are 5 of the most fuel-efficient non-hybrid C-segment sedans in 2026.
Honda Civic: 6.5 liters/100 km
The Honda Civic is the most fuel-efficient model on the list, with a combined consumption of 6.5 liters/100 km. On the highway, this figure is even lower at 5.7 liters/100 km. Even in city driving, the car can still achieve 7.4 liters/100 km.
