Hyundai Motor Co., South Korea's largest carmaker, launched its all-new Sonata on Monday as part of efforts to expand its presence in the global mid-size sedan market, announcing its aim of selling 228,000 units in the first year. The company said the car features "refined styling" thanks to its "Fluidic Sculpture 2.0" design philosophy, has better driving characteristics than the outgoing model and incorporates top-of-the-range safety features.
