12.Audi A3 Sportback e-tron
Luxury and fuel efficiency meet in the 2017 Audi A3 Sportback e-tron. Compared with other fuel-efficient sedans in the market, the Audi A3 is considered more luxurious and upscale. The luxury that comes with the Audi A3 can be found in its interior, thanks to the use of real leather, heated front seats, iPod interface and a $2600 technology package. But the true selling point of the Audi A3is its fuel efficiency, with an EPA-rated 83-86 MPGe. This kind of performance submitted by the Audi A3 e-tron is more than enough to beat the numbers submitted by the Chevrolet Volt and the BMW i3.
