Yamaha actually were involved in the design of the 2 liter inline 6 of the Toyota GT2000 of the late 60s. Sort of a japanese version of the Jaguar E-type. A beautiful car, and a beautiful engine.

And some info.

I took both of the above pictures when I visited the Yamaha museum in Iwata in 2017.
Some claim that lessons learned from this car engine, was incorporated in the XS650. Which makes a lot of sense, as a 653 cc twin is very close in individual cylinder capacity to a 1988 cc six.
BMW did something similar when designing the 75/5 motorbike, using some experience (crank bearing sizes, Etc) from their 2800 cc six cylinder car engines.

From everything I have read about the Yamaha engine program, they were over weight, under power, and not quite stiff enough as a stressed member. But that's what people say about every failed F1 engine.

The car looks like a blast. I had a dream about a 2 stroke front engine street legal sports racer last night. It was an odd beast.

I remember seeing the blue Ford oval on Kenny Robert's OW81 at Laguna Seca in 1985.
