Toyota was impressed however and BRE’s work with Hino led to the construction of the visionary Toyota JP6. The JP6 was a brilliant combination of body and chassis design. Brock chose Trevor Harris and Bruce Burness to design and fabricate the chassis. It featured a revolutionary suspension geometry that enabled the tires to contact the ground with minimal tire scrub. The body was designed so that as the car’s speed increased the body’s moveable aerodynamic devices would push down on the chassis giving greater adhesion. These were revolutionary ideas in 1967.
Due to Toyota’s sudden and unexpected decision to transfer their race program over to Shelby American, Toyota abruptly took possession of their assets at BRE, including the semi-completed JP6. Brock was concerned as he knew no one else would understand the relationship between the body and the chassis that Harris and Brock had worked on so closely. Unfortunately the worst scenario occurred… Toyota’s engineers, with no idea of what the car might do on the track, finished the car in whatever manner they saw fit, creating some serious instability problems and it was destroyed in their first test in Japan.
