... FORD SVT! 
Forgive me if you knew this but I just learned it. I was watching a show that had a CCX on it and they did a very quick glimpse of the engine but I recognized thoes heads and intake right away
So I just did some reserch and while they dont show it on their home page I did find what I was looking for. And the thing runs on gas OR diesel, makes 1018hp on biofuel
But how about that? They wanted to make the fastest car ever and out of all the engines they could use, they choose a Ford modular engine
I so want the carbon fibre tid bits
And for thoes of you not familiar with Konisgegg:
