918と言うことは、917の次（後継）ですよね。
918RSRですが、エンジンカバーにファン（公道仕様にはなし）が付いてます。

I filmed the new supercar from Porsche on some typical German countryroads in the surrounding of the Nurburgring Nordschleife.
We were visiting the Gran Turismo EVO event on the Nordschleife when we saw some automotive journalists, like Chris Harris from Drive and Harry Metcalfe from Evo. We suggest they were there for a press preview of this pre-production hypercar! There were a total of 5! 918 Spyders. Unfortunately I was only able to capture this one, because I was driving while we were following them. I suggest you look up Shmee150's video for more footage! Enjoy!
