We’ve seen several interesting entries from the Porsche Unseen book in the past few weeks. One of the more remarkable entries in the 328-page odyssey of recent Porsche design is the Vision 918 RS, a street legal hybrid electric hypercar that was most suited to track driving.

The Vision 918 RS picks up where the 918 Spyder left off in 2015. It’s a considerably more businesslike design, however, with a center cockpit and a more aggressive and futuristic shape. As an indication of things to come, it looks suitably iconoclastic.

Other unseen Porsches we’ve looked at this fall: the Le Mans Living Legend, an homage to a 1953 24 Hours of Le Mans winner, and the Vision 920, a striking road and track design.
