Completely frickin' insane. That's pretty much the only way to describe the Pagani Zonda R and the minds behind its creation. As the purebred racer of the Zonda fold, the sculpted carbon fiber ludicrousity of its street counterparts melts away into pure sound and function on the track. And this video captures its essence.
Watch for the green button at about 1:36 for the start of the auditory manna, as the Zonda R's maniacal Mercedes engine kicks over and begins its banshee wail around a rain-soaked track. But don't skip the first minute-and-a-half, either, as there are some exquisite shots of the car denuded of its shell, as well.
And for a bit more under-the-skin action, check out the first official Pagani Zonda R trailer here.
