Unadulterated, bombastic carbon-fiber insanity--the current Pagani Zonda and its several variants are the embodiment of what it is to be a supercar. But sadly, the car was never officially sold in the U.S. and only a handful have made their way here under special Show & Display rules.

That won’t be the case with the Zonda’s successor, the code-named C9, which has already been spied testing in prototype form on a number of occasions.

The C9 is said to be a completely new car, from concept, weight distribution, materials and dynamics. In fact, it will feature more than 3,770 new parts among which are a carbon-titanium chassis, specially developed Pirelli tires and Bosch electronics. It is also being designed with U.S. homologation fully in mind, which means the car will meet California’s latest 2013 emissions regulations as well as EPA and DOT standards--something the Zonda never did.

Power will come from a twin-turbocharged 6.0-liter V-12 engine built by AMG, and should top out at 690 horsepower and 737 pound-feet of torque.

The Pagani C9 supercar is expected to make its world debut at the 2011 Geneva Motor Show next March. Pricing is expected to start at roughly $1.2 million.
