Yamaha supplied engines to different vehicles on the grid, such as Zakspeed, Tyrrel, Arrows, Jordan and Brabham, in the late 80's and early 90's.

From that expertise was born the OX99 V12 3.5-liter engine, which was used in the ox99-11, an interesting project that was abandoned for economic reasons.

A real shame, as the light Japanese sports car had more than 400 hp (298 kW).
