Our friends at Fast Lane Daily have provided fresh speculation to the rumour that the next generation Pagani Zonda will use the SL65 AMG Black Series six-litre V12 by scooping some spy shots of the two development mules side-by-side. We have previously reported on the Zonda, back when we were unsure what the new engine could be, now however it seems more than likely that 661hp Black Series engine possibly in a higher state of tune. We look forward to seeing the final production ready versions of both cars.
