On the eve of launching an all-new supercar, supposedly to be called the C9, Pagani
has built another extremely rare Zonda. How rare? Only one has been built. Called the Pagani Zonda RAK, it's powered by a 7.3-liter V12 AMG engine. Based on the now out of production Cinque, Pagani is claiming the power output from the RAK is rated at 678 horsepower at 6,400 rpm and 575 lb-ft of torque.
