Remember that mystery track that was featured in the KAZ documentary livestream last February? Yesterday, Polyphony Digital invited a few Super GT drivers to their office for a friendly battle where it was streamed in NicoNico. One of the tracks featured was that track, now known as Circuito de la Sierra.

According to GTPlanet, the new Spanish-based track will be featured next week via Update 1.12. ALL ABOARD THE HYPE TRAIN!
