The 2017 Hyundai Elantra Eco is the most fuel-efficient Elantra which can be bought at an affordable price of $21,485. The car comes with a number of technologically advanced features encompassing seven-inch display audio touchscreen with Android Auto and Apple CarPlay support, blind spot detection with rear cross-traffic alert and lane change assist, proximity key with push-button start, heated front seats, dual automatic temperature control and a leather-wrapped shift knob and steering wheel with audio, cruise and Bluetooth controls.

The fuel efficiency ratings are phenomenal and it could only cost you $900 annually thanks to its fuel-efficient 1.4-litre turbocharged four-cylinder engine which delivers 32/40 mpg city/highway. The engine is mated to a seven-speed EcoShift Dual Clutch Transmission with Shiftronic®. The combined fuel economy is 35 mpg, which is the same as the Honda Civic, Chevrolet Cruze, and Toyota Corolla Eco.

Comparing the price of 2017 Hyundai Elantra Eco with the competition, it is around $1,000 to $1,500 more expensive, but that a price customers have to pay for advanced standard features.
