1997 Lamborghini P147 Acosta

This concept, proposed by Marcelo Gandini as the successor to Diablo, was presented in parallel to a prototype conceived by Zagato, the P147 Canto. Despite respecting the cost parameters of the project while maintaining the roof, the door profile, and the windshield of the Diablo, this model was not at all appreciated. As a result, no prototype of this one-off concept was built.
