Some of the most fuel-efficient hybrids on the market include the Toyota Prius, which gets up to 58 mpg in the city and 53 mpg on the highway, and the Hyundai Ioniq Hybrid, which gets up to 57 mpg in the city and 54 mpg on the highway.
The fuel efficiency of hybrid cars is due to their combination of a gasoline engine and an electric motor. When the car is coasting or braking, the electric motor generates electricity that is stored in the battery. This electricity can then be used to power the car's electric motor, thus reducing the amount of gasoline that is used.
In addition to improved fuel efficiency, hybrid cars also produce lower emissions than gasoline-powered cars. This is because the electric motor does not produce any tailpipe emissions. As a result, hybrids are a more environmentally friendly option than gasoline-powered cars.
