Details are not yet available. But we imagine that the Sonata update will include redesigned aesthetic elements and re-packaging. To help us visualize, Hyundai has released several photo teasers. From this, we can see tidbits of the new front end design and the radiator grille, which seems to repeat other updated Hyundai models, such as the recent Elantra GT.
Refresher
Hyundai Sonata is a venerable mid-size company sedan competing with cars such as Honda Accord, Toyota Camry, Nissan Altima and so on. It is available with a base 2.4-liter naturally aspirated in-line, more powerful 2.0-liter turbo four, and a 1.6-liter hybrid turbocharged version with plug-in.
