First unveiled back in 1999 at the Geneva Motor Show, the Pagani Zonda is about to get its biggest overhaul in its 10-year history.

The 2010 Zonda F will get an all-new front clip, re-sculpted rear quarter panels and a totally new air scoop that sticks up from the middle of the engine cover.

Under the hood Pagani will place either a 5.4L supercharged V8 from the McLaren SLR 722 or perhaps the bi-turbo V12 from the recently debuted Mercedes SL65 AMG Black series, but this is still a secret. In both cases the output should be around 600-700 hp.
