2.4L 4-Cylinder Atkinson-Cycle Hybrid. Wow! Where do I start?! Success starts with Hyundai of El Paso! Hyundai has outdone itself with this terrific 2015 Hyundai Sonata Hybrid. It just doesn't get any better or more fuel-efficient. A spacious car that gets great fuel mileage... Why torture yourself driving a small commuter box up and down the highway every day when you can ride in roomy comfort.
