Kelley Blue Book has awarded the most fuel-efficient luxury car of 2015 to the BMW i3. The BMW’s i3 wins this for the second year in a row. The car guide says that the i3’s design is modern and fresh, and truly stands out on the road. Not only is the i3 the most fuel-efficient luxury car, it’s the most fuel-efficient car, period. Adding a cure for anxiety is an available range-extending gas engine. BMW i3 is followed by the 2015 Tesla Model S 70D and Mercedes-Benz B-Class.
