Promotional clip surfaces online ahead of Detroit unveiling next week.

The Toyota Supra has surfaced once again, this time through the official reveal video presumably meant to be shown at the reborn sports car's unveiling in Detroit on January 14.

During the 45-second clip, the red coupe can be seen revving its turbocharged inline six, and tearing up a dark under-bridge car park.

It also confirms the leaked images from a fortnight ago were legitimate, with the exterior design looking just like the leaked promotional images.
