2014 Corvette C7 scheduled official unveiling on 13 Jan, 2013 but it seems we will know every thing about the car before that date.
The images were posted to Corvette Forum by a user who said “I don’t work for GM or anyone associated with GM. I have, for months, been sent information by a variety of people ahead of what has been published. Why, I’m not sure. Until now, I have kept it all to myself. What you will ultimately see here is all I have and I cannot vouch for it’s authenticity.”
The drawings looks like from car manual featuring 2014 Corvette’s profile, rear end design ,tail lamps and a detailed outline of the interior, including the driver-centric dashboard.
