The Hyundai Sonata is redesigned for 2015 with a more refined look and a larger cabin. A new Eco trim level with a 1.6-liter turbocharged four-cylinder engine also debuts, although the more powerful 2.0T trim level has nearly 30 fewer horsepower. The 2015 Hyundai Sonata further refines the midsize sedan formula with a new look, revised powertrain and plenty of tech and convenience features. If you want plenty of passenger room and a quiet, easy-to-live-with cabin, this Sonata definitely has what you’re looking for.
