History
The car began as the Centenaire, shown at the 1990 Monaco Grand Prix and designed by Fulvio Ballabio. Its engine was a Lamborghini V12 of 492 bhp.
For production it was renamed Monte Carlo GTB, and the Lamborghini V12 was replaced by a 4.0-liter twin-turbo V12 designed by Carlo Chiti. The article planned five cars for 1992 and fifteen a year after that.
The tub and larger carbon-fiber body parts came from Italy, with final assembly in Monte Carlo. The body was credited to Castagna.
