Lamborghini unveiled their own birthday present to itself for its 50th anniversary party last year - the one-off Egoista. Now the concept has returned home in Sant'Agata Bolognese, Italy, where it will be permanently displayed at Lamborghini's headquarters.

Developed by Walter De Silva, head of Volkswagen Group Design, the mad single-seater supercar takes Lamborghini's aeronautic theme to the extremes, with inspiration coming from the Apache attack helicopter and jet fighters.

Made from lightweight carbon fiber and aluminum finished in a military-grade, radar-resistant paint to highlight the vehicle's stealth capabilities, power comes from a tuned version of the Gallardo Mk1's 5.2-liter V10 churning out 600PS (592hp).

It's a shame they won't be mass producing this.
