You can opt for either the manual gearbox or the automatic transmission, with a standard or a sporty suspension, and in either case the 2014 Accent is rated at 28 mpg in the city, 37 mpg on the highway.
With the manual gearbox, you get an "eco" shift light to help train you to use less fuel, though, while the automatic has an ActiveEco button that triggers early upshifts to improve gas mileage.
Compared to other vehicles in its size and price class, these numbers are competitive, but definitely not the best. We've seen close to the EPA numbers, provided we can keep the revs relatively low.
That leaves a pretty long driving range. Fill up the tank and the Accent could go as far as 400 miles without another stop. Wring it out, or leave in Sport, and you're sure to land at the lower end of that scale however
