The first official-looking photo of the Zonda successor has emerged on the 
internet. We don't want to jump to any conclusions about the design, so we will 
just wait for the official release, which is reportedly due next week.
The website that first ran the photo, carsuk.net, explains that they've "had the 
photo for a while, but didn't want to run it and break a confidence. But now the 
Huayra has already been revealed it makes sense to publish the actual photo we 
were sent."
"Maybe the Huayra will grow on us. Maybe it looks better in 
the flesh (no, we haven't seen the actual car). But when you consider the 
underwhelming design of the Huayra and the problems we know Pagani are having 
with both the Huayra shakedown and its production, things aren't looking 
brilliant for Pagani."

UPDATE 1/22/2011: Five scanned images of the Huayra from a Spanish magazine 
have been uploaded.
