After two years, the Huayra ragtop has finally arrived. But it’s in a hurry. In fact, it’s already gone.

Outfitted with a specially-designed AMG 6.0L V12 twin-turbo engine, the Roadster has nearly 800 available horses to call upon, as well as 737 lb-ft of torque. Pagani assures buyers that the 1.8 G’s available at takeoff may simultaneously cause intense euphoria and mild whiplash.

The design is typically Pagani—Formula 1, but couture. The trademark leaf-shaped sport mirrors have been retained, a little art nouveau flourish. The monocoque is fabricated from carbotitanium, a proprietary material developed by Pagani that is a lightweight, rigidly synergistic combination of both materials. The car is sold with two roofs: a carbon fiber hardtop, and a fabric top that is squirreled away in the Roadster when not in use, but may be attached manually, with expediency.

The car is equipped with British supercar transmission specialist Xtrac’s 7-speed gearbox, which will help the Roadster to its top speed; no word, yet, on whether or not the Roadster 0-60 time has been improved via tuning and tinkering to best the standard Huayra’s time of 3.0 seconds. All that juice needs stopping power, and the Pagani is equipped with 380mm carbon ceramic Brembo brakes. Custom Pirelli tires keep the Roadster tracking true.

All that, and on the green side of a V12, too. The Roadster is expected to be on the angelic side of emissions—for a hypercar—and Euro 5 compliant, following the lead of its older brother.

Pagani is building 100 examples of the Huayra Roadster, and all have already been pre-sold…at around $2.4 million each.
