The new 2015 Hyundai Sonata , which debuts the new Fluidic Sculpture 2.0 design language, has been showcased at the 2014 New York International Auto Show . The 2015 Hyundai Sonata's design is more refined and the car's front end has become all the more sophisticated. It may be noted that the 2015 Sonata is considerably safer than the outgoing model, which is due to the increased use of Advanced-High Strength Steel (AHSS) on the platform.
