Most fuel efficient cars
The most fuel-efficient vehicles by type according to advertised and actual fuel consumption in relation to vehicle performance. Actual fuel economy estimates are based on aggregated reports from over 750,000 vehicle owners from multiple sources.
User-reported fuel consumption may not accurately represent all users' experiences due to variables such as driving conditions, driving style, technical condition of the vehicle, and other circumstances. Thus, it should not be relied upon as a representative indicator.
