Around a month ago, Toyota posted an image to its Instagram page of what looked like your average U.S.-spec Corolla interior. Now, users of grcorolla.com have reported finding numerous Easter eggs hidden in the teaser pic, all of them decisively pointing towards the upcoming premiere of a GR-badged Corolla.

In all likelihood, the car will have the same feature set as the famous GR Yaris, and come based on the same drivetrain. Note the caption ‘G:16’ on the dashboard: the GR Yaris uses a turbocharged three-cylinder engine known internally as the G16E-GTS.

Elsewhere, there is a navigation map with a road named GR Four, a rather clear hint that the car may have a four-wheel drive system. The numbers 2 and 68 on the climate control panel echo the power rating of the Yaris in the North America (268 hp). The one mystery remaining unsolved is the lack of an audio speaker on the a-pillar to the right. Finally, the top right corner of the photo depicts what could very well be the camouflaged GR Corolla running its pre-production tests. It looks like a five-door hatchback.
