The car is inspired by the longtail Le Mans racers of the 1960s. The two clients approached Pagani in 2018 about a longtail variant, working with the company for over two years to finalise the styling concept. Pagani then made one-quarter and full-size scale models show to clients before starting production.
The result is the Huayra Codalunga. Pagani poured extensive resources into the project to ensure it complied with global regulations, which is much work for just five cars. The large rear engine cover hides a potent V12 that develops 840 horsepower (617 kilowatts) and 811 pound-feet (1,100 Newton-meters) of torque.
