The Most Fuel Efficient Passenger Cars
Over the last 10 years, fuel efficiency has become more and more important thanks to the rising costs of fuel. While the national average has grown over the last 10 years, only 4 vehicles have held the title of “most fuel efficient passenger cars” during that time. Below are the most fuel efficient cars for the last 12 years, as well as the national average of fuel efficiency for each year.
You can see that even though the fuel efficiency of the top car each year has nearly doubled over the last twelve years, the national average for fuel efficiency has grown by roughly 5 miles per gallon on average.
