Derek D and the boys at Fast Lane Daily have scored an interesting pic of the next-gen Pagani Zonda buddying up with the Mercedes-Benz SL65 AMG Black for high-altitude testing in Colorado. This, of course, sets up rumors the new Zonda will have the same 6-liter V12 expected in the Blackest of SL's, instead of the anticipated V8. We're pretty sure nobody in the supercar world will complain about a frenetic 600 HP V12 making noise in the new Pagani. Check out the Fast Lane Daily video below the fold for details, and the shout-out to yesterday's shocking BMW F1 news.
