View rankings of the most fuel efficient cars below, ordered by vehicle type. Below is also a list of the least fuel efficient vehicles, also ordered by vehicle type. It is no accident that the most fuel efficient cars in some classes are hybrid-electric vehicles (HEVs). Hybrid cars can be configured in many different ways to achieve a variety of different objectives. They combine the best features of the internal combustion engine with an electric motor and can significantly improve fuel economy without sacrificing performance or driving range.
