The most extreme Pagani ever. The Zonda R is not road-legal, thus it can be driven only on racetracks and it serves as an exercise into what the company could do.
It barely shares any elements (just 10%) previously developed for other Zonda models. Zonda R is powered by a 6.0-litre engine built by Mercedes-Benz AMG division which is also found in the CLK GTR. The V12 develops an astonishing 750hp (552kW) and 710Nm of torque.
Asking price is $1.8 million and they are building only 15 customer cars.
