Pagani Huayra Roadster – How Its Made – Video

Pagani Huayra Roadster – How Its Made – Video

One of the main goals was to make this car lighter than the coupe, and with a claimed final dry weight of 2822 pounds, the roadster takes the crown by 176 pounds. The central tub is constructed from a combination of two carbon-fiber weaves that Pagani calls carbo-titanium and carbo-triax HP52. The front and rear substructures are made from steel tubing. Along with making the car lighter, the roadster is said to be 52 percent stiffer, which is a surprising change in the conversion to a convertible.

The open-air experience is enabled by two removable roof arrangements. One is a carbon-fiber lid with a large glass panel that provides a coupelike appearance when installed. The other is a carbon-fiber framework covered with fabric that can be stored in the car for use in inclement weather.

 

 

The Mercedes-AMG M158 twin-turbocharged 6.0-liter V-12 was designed and built specifically for Pagani. During development of the BC, Pagani massaged the engine to 754 horsepower at 6200 rpm and 737 lb-ft of torque at 2400 rpm, and that output applies here. The roadster also carries on the BC’s seven-speed automated manual transaxle built by motorsports supplier Xtrac. It differs from most longitudinal mid-engine transaxles in that its guts are turned 90 degrees to reduce the polar moment of inertia and improve handling. An Automac Engineering–tuned ECU pairs with hydraulic and electronic actuators and carbon synchros for smooth shifting. The electronically controlled limited-slip differential was co-developed with Bosch. Overall, Pagani claims the gearbox is 40 percent lighter than the previous unit used in first-generation Huayras.
