Pagani Zonda And Mercedes SL65 AMG Spotted Testing Together

A spy shot of two test mules described as the Pagani Zonda and Mercedes SL65 AMG Black Series has surfaced all across the web and many of us are wondering why the two are testing together. The only obvious answer is that they both share the same powerful engine stored underneath their hoods.

While that may be the case, it could be a simple instance of AMG doubling-up on their test time, since Pagani renewed its engine deal with the Mercedes tuning house. Previous reports suggested that the supercharged V8 from the outgoing SLR McLaren could be flipped around for duty in the next-gen Zonda, however the SL65 Black uses a much larger 600hp twin-turbo V12.
