What you’re seeing is yet another Pagani Zonda one-off, called the Absolute.
The Zonda Absolute appears to be based on a Zonda Cinque. Changes from the standard car are purely visual. It gets black rims, a “dark” interior, and a bare carbon fibre paint job which blends gloss and matte carbon fibre. There’s also a racing stripe featuring the colours of the Italian flag.
The customer’s identity is unknown, but we do know that he/she lives in Hong Kong.
