This just in from Hyundai: the South Korean automaker published a pair of teaser sketches previewing the all-new 2011 Sonata YF. Unfortunately for Hyundai, the drawings were released only a few hours after a set of official shots leaked all over the internet. And even though the actual production model is very close to the vehicle depicted on the drawings, let’s just say that it’s not as aggressively styled as the design sketches imply.

According to Korean media, the next-generation model of Hyundai’s mid-size sedan will be fully revealed on September 10, so stay tuned for more details.
