Turin Auto Show
The convertible iteration of the Biturbo was designed and assembled by Zagato in Milan. It was Zagato's first work for Maserati since the A6G/2000 thirty years earlier. Embo of Caramagna was first commissioned to develop a four-seater cabriolet version of the Biturbo, which was shown at the April 1982 Turin Auto Show, but their proposal never made it to production.
