however, Yamaha requested a two-seater vehicle and a tandem seating arrangement was suggested which was in keeping with Yamaha's motorcycle expertise. This resulted in a radical and somewhat outrageous design based on Group C cars of the time, with features such as the cockpit-locking roof. It also shared the same chassis as the Formula 1 car, to try to give the consumer market a pure Formula 1 experience. Eventually disagreements with IAD over the budget made Yamaha take the project to its own Ypsilon Technology which was given six months to finish the project, otherwise it would be terminated. To make matters worse, Japan was in the midst of an economic downturn, which made Yamaha believe there would be no customers for the car, and so the project was cancelled in 1994 after many delays, with only 3 prototypes in existence.
