Pagani Technology

With a naked, clear-coated carbon-fiber body and monocoque chassis, the Huayra weighs 1,400 kilograms (3,100 pounds). 

Uniquely, Pagani also weaves titanium into the carbon fiber to boost rigidity and spread kinetic energy in a crash. To achieve street legality in the United States, the Huayra had to pass 47 crash tests using a pair of carbon-fiber monocoques that Pagani says remained usable despite repeated destructive tests. 

The engine is built by Mercedes-AMG to Pagani's specifications, including a 1,000 newton meters (738 foot-pounds) of torque, and it's mated to a seven-speed single-clutch automated manual transmission. A single clutch was used unlike a lot of dual clutch cars nowadays in an effort to save weight.
