While the 2015 Hyundai Sonata is a completely redesigned vehicle for the new model year, the Sonata Hybrid for 2015 continues to use the previous-generation body. This has led to a certain amount of speculation about what direction Hyundai plans to take with its hybrid program. Now, it appears that the company will launch the hybrid version of the current Sonata with the option of a plug-in hybrid model as well as one fitted with the next generation of the company’s conventional hybrid-electric powertrain.
