The U.S. Department of Energy has just released its list of the top ten most fuel-efficient vehicles for 2014. At the top of the list is the all-electric Chevrolet Spark EV, with a combined city and highway average of 119 mpg equivalent. The Spark averaged 128 mpg in the city and 109 on the highway. The overall electric range for the Spark EV is an estimated 82 miles, though that will vary.
Meanwhile, the Chevrolet Volt came in at number seven on the list, averaging 62 mpg. Overall, the top seven cars on the list are electric vehicles, and the bottom three cars on the list are all plug-in electric hybrids. So if you are in the market for a new car and looking to not only reduce carbon emissions but to save money on gas as well, it seems that your best bet would be to go with either an all-electric vehicle such as the Chevy Spark, or a EREV such as the Chevy Volt. Pricing for the Spark EV isn’t bad either, though availability is very limited, as it’s only sold in California and Oregon currently.
