Porsche 918 Spyder prototype Rolling Chassis
The sign explaining the car said that this prototype is actually based on a Carrera GT chassis. As you can see the engine and exhaust system are clearly 918 pre production parts. Some odd touches were the taillights from the 991.1 as well as parts of a cayenne or Panamera Center console and 911 front fenders with the iconic fuel filler hole. Unfortunately both of the aforementioned quirks are not visible. Hope you enjoyed this look at the earliest driving prototype of my favourite modern Porsche.
