A 2015 Hyundai Elantra is a reliable, fuel-efficient compact sedan known for offering strong value, a quiet ride, and a surprisingly spacious cabin for its class. Powered by either a 1.8-liter (145 hp) or 2.0-liter (173 hp) 4-cylinder engine, it serves as a comfortable, easy-to-maintain daily commuter with up to 38 MPG highway.
