What I'm trying to say is if you put the two next to each other for a race, you'd expect a Koenigsegg to take it. However, the GTR's ability to take on extreme modifications make it quite the sleeper in just about any race.
A perfect example of the GTR's ability is the video, found below, of a Koenigsegg CCX taking on a Nissan GTR in Turkey. Even from the rear, the Koenigsegg looks like a rocket ship ready to blast off.
But, when the two line up and hit the pedal, the GTR becomes the real rocket. Check out the video below to see the race in action (we do not the condone the act of speeding on public roads; always follow your local traffic laws).
