Lamborghini unveiled the mysterious roof-less supercar it has been testing on and off the track for the past few months. Called SC20, it's a one-of-a-kind model positioned at the intersection of road cars and track cars.

Developed by Squadra Corse, the firm's in-house racing division, the SC20 was built at the request of a customer who eagerly participated in nearly every step of the design process. Lamborghini explained the project's goal was to transfer some of the lessons it learned on the track (notably those related to aerodynamic technology) to a street-legal car that falls in line with its current design language without copying an existing model.
