Motori Moderni
The first car was powered by a Motori Moderni Flat-twelve engine, a detuned Formula One engine rated at and originally built for Subaru, and then in 1990 a second concept was built with a Judd GV V10 engine, new twin circular taillights, and more traditionally styled side mirrors. The reason being that Subaru took the engine to use in its Formula-one car for the 1990 season. Seeing the disappointing results, Subaru pulled the plug on the project leaving Jiotto without an engine supplier.
