For the fourth straight year, gas mileage efficiency was the most influential reason consumers in the United States purchased their chosen new vehicle.

The statistics are annually compiled by the automotive analyst company, J.D. Power. But a unique situation is now also occurring in the automotive industry.

While good gas mileage is still important, it’s not the dominating reason it once was. With gas prices falling close to nearly $2 per gallon, buyers are considering other factors with renewed interest, including comfort and performance.

Still, in 2012 the auto industry and government established a new regulation of 54.5 mpg as the U.S. fuel efficiency standard required by 2025.

In 2014, the U.S average mpg in new cars reached its highest, nearly 26 mpg. The average has recently slightly fallen, with other purchasing factors on the rise.

But the auto industry also appears to be making strides toward more fuel efficiency, with more hybrids and electric-only vehicles debuting in the marketplace.

In 2016, the 10 best fuel mileage cars in the United States are all electric vehicles and they include a wide spectrum of prices.

The most expensive car on the list via its base MSRP is the Tesla Model S ($71,200). The least expensive car on the list is the Mitsubishi i-MiEv ($22,995).

(The prices stated are before varying states’ and federal incentive rebates.)

The most fuel-efficient car in the United States is the 2016 BMW i3 BEV. The 2016 edition will be available to the public, according to BMW, in July. It’s predicted to achieve a combined 124 mpg in city/highway driving.

Here’s the list of the top-10, in reverse order, of the most fuel efficient 2016 cars, according the EPA statistics. Each vehicle listed includes the engine type, price and combined city/highway gas mileage average:
