The Huayra might have succeeded the Zonda, but Zonda is still a special car for many. Especially, for the founder Horacio. Which is why he commissioned the Zonda HP Barchetta, for himself, reportedly to celebrate his 60th birthday.
Only 3 of these will be built, and the factory will be done with the Zonda. As you might have guessed, the other two are reportedly sold out. This particular example has chopped windscreen and partially covered rear wheels with carbon.
The car still has Mercedes-AMG built 6.0-litre V12, probably with an output of close to 800 hp. The gearbox is a 6-speed sequential manual.
