While almost anything faster than a GT3 is above my pay grade, it's hard to resist the Porsche 919 hybrid; the fastest car I've encountered in AC thus far (not counting fantasy vehicles like a 2525 landspeeder). And there's only one place to see if you're as good as you think you are, and that's the Nordschleife. Yes, the 919 transports you straight to Heisenberg territory: time slows down, circles go all elliptical and straight lines shimmer and shake like an overstressed zip line. Finding the right setup took one whole crazy night, but it was worth it. Properly hooked up, the 919 floats you through the Zone as if on wings, its wheels barely touching the ground as you hurtle through the dark shadows of the Green Hell. An hour later, my corporeal self is still vibrating like a tuning fork. If you think I've nailed it, let me know.
