Pagani and AMG have quashed rumours that the upcoming C9 will be powered by the V12 from Mercedes' Black Series. Horacio Pagani has confirmed that AMG will remain the sole engine supplier for Italy’s only remaining independent supercar manufacturer. All Pagani cars have been powered by AMG’s non-turbo V12 since the original Zonda was launched in 1999.With the Zonda now retired, speculation had been rife that the company’s new C9 supercar would simply inherit the current SL65 Black Series six-litre twin-turbo V12. This has now been confirmed not to be the case. In a joint statement, Pagani and AMG said: "The engine of the Pagani C9 is not a derivative of the AMG V12 developed for the SL65 Black Series; neither is the AMG V12 in the SL65 Black Series derived from the engine AMG is developing for the Pagani C9."The engine in the Pagani C9 has been developed specifically for that application by Mercedes-AMG."Production numbers have yet to be confirmed but the C9’s V12 is expected to produce 515kW, 23 more than the current Black Series V12.
