Jiro Kawano , who was also involved in the Toyota 2000GT , played a key role in the design and development of the Toyota 7. However, cooperation partner Yamaha took over the development and construction of the vehicle.
In its debut race, the Toyota Seven was powered by a 3-liter V8 engine with double overhead camshaft ( DOHC ).
The prototype for the first tests in Suzuka was still equipped with a 2-liter injection engine from the 2000GT.
