The seventh generation Hyundai Sonata offers a more refined look through a new Fluidic Sculpture 2.0 design language, stiffer body structure, better ride quality, reduced noise, vibration and harshness and advanced safety and convenience features. Sonata truly democratizes the premium design and convenient technology of the Genesis sedan for the mid-size class.
A rigid platform is essential for a great car. Everything from ride quality to crash test performance is enhanced with a stiffer platform. The 2015 Sonata uses advanced high-strength steel for more than 50 percent of total platform composition, which results in 41 percent stiffer torsional rigidity and 35 percent greater bending strength. Advanced high strength steel is twice as rigid as traditional steel while weighing 10 percent less. More hot-stamped components are used, especially in the B-pillar area.
