7. Chevrolet Spark - 34 MPG Combined
The cheapest car on our list is the Chevrolet Spark which was clearly developed to offer impressive fuel economy. The 1.2-liter engine is puny, offering only 84 hp and 83 lb-ft of torque, but the compact city car does seat four comfortably while its $12,170 price tag will surely impress even the stingiest car shoppers. Best of all, it’ll save on your stops to the gas station with its 31 mpg city, 39 mpg highway rating. On average and equipped with a five-speed manual, it should average 34 mpg.
