Eyebrows were raised when a photograph from the Rockies began circulating the interwebs. The rare shot shows a pair of delectable supercar test mules – the next-generation Pagani Zonda and the new Mercedes SL65 AMG Black Series – undergoing testing side-by-side on public roads. Aside the from the rare occurrence of a non-homologated Zonda on American tarmac, speculation began to ramp up as to what the two were doing together. Conclusion: they must be sharing the same engine.

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. Of course it's impossible to tell at this point, but we'll be keeping our eyes peeled in the meantime.

The world's major sportscar-makers all have major parent companies behind them: Ferrari and Maserati have the Fiat Group while Lamborghini (and Bugatti) are under the VW/Audi umbrella. Pagani Automobili SpA, however, remains independent, but hooked up with Mercedes to provide the motivation in the heart-racing Zonda supercar. Not to worry, though, because by all accounts the V12 engine that AMG builds by hand for Pagani is an awesome powerplant. Its displacement and output have increased from six liters and 408 horsepower in the original C12 to 7.3 liters and 602 hp in the latest Zonda F. With dedicated development like that, it would be foolish for Pagani to look elsewhere or consider designing its own engine. So it's probably a good sign that Pagani and AMG have renewed their partnership, the fruits of which we're looking forward to seeing in the highly anticipated successor to the Zonda, whenever it debuts.
