It was created by company founder Horacio Pagani and his team for Pagani's own 60th birthday as a tribute to the car that was first introduced 18 years ago. It's possible they will be the last three Zondas built.
The HP Barchetta is the work of the Uno-di-Uno division, which consists of a team of specialists that create one-off and extremely rare customized cars that supposedly exceed the Zonda's (and Huayra's) usual high-quality standards.
Noteworthy elements include the cropped windshield, carbon-titanium composite components from the Huayra and the contrasting wheels - those on the left are silver, those on the right are blue. Inside, the seats are from the Huayra and done up in ivory leather with tartan elements and blue leather highlights. The steering wheel is also trimmed in blue leather and wood - the latter one of the several elements inspired by classic motorsports.
Power comes from a Mercedes-AMG V12 sent through a six-speed manual transmission. Carbon-ceramic Brembo brakes handle the stopping.
