Yamaha also tried to produce a supercar in the 1990s, named the Yamaha OX99-11. It was made as a supercar to have an Yamaha Formula 1 engine as its powerplant and have Formula 1 technology in it. Even though their engines did not win a Grand Prix, by 1991 the team had produced a new engine, the OX99, and approached a German company to design an initial version of the car. Yamaha was not pleased with the result as it was too similar to sport cars of that time, so it contacted IAD to continue working on the project. By the beginning of 1992, just under 12 months after starting to work on the project, IAD came with an initial version of the car. The car's design was undertaken by Takuya Yura, and was originally conceived as a single seater. However, Yamaha requested a two-seater vehicle, and a tandem seating arrangement was suggested, which was in keeping with Yamaha's motorcycle expertise 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, this resulted in a radical and somewhat outrageous design based on Group C cars of the time, 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. But 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.
