It's called the Huayrab.
In one sense, all Paganis are one-offs. After all, each is customized to customers' exact specifications. Commissioned by Alejandro Salomon, this particular model, dubbed the Huayra 730 S and nicknamed "The Huayrab" has received a fully-exposed carbon-fiber body, with blue-tinted windows, golden Zonda wheels, Zonda R lines at the bottom and Tricolore line on the top, while the Italian flag features on the brake calipers and mirrors.
The interior is apparently "not the color you see on the render." However, under the hood will be the colossal AMG-sourced 6.0-liter twin-turbo V12 pumping out 730 hp and 737 lb-ft of torque.
