I had dismissed it as a silly concept vehicle, but that has proved me wrong. Thank you.

I thought this engine would turn up on his channel,he doe's some excellent uploads

The most practical aspect of this design was not touched on in this video. It is that by using a large electrically controlled supercharger the air flow into the engine does not need to be controlled solely by mechanical means, i.e. the valves and camshafts. This allows, in effect, for variable compression ratios and hence a cleaner running engine which could prolong the life of IC engine use in motor vehicles. It would only work properly when used in conjunction with electronic transmission control which is already coming to market in some Honda models.

Even so I would not be optimistic about the overall design being economically viable so I don't think it will reach production, at least not in V3 layout.

What sort of layout is more likely, in your view?

From an economic perspective any layout that doesn't need extra discrete components such as cylinder head camshafts and timing gear. Having said that Honda's record for unusual one-offs such as oval pistons v-fours and flat fours means that nothing can be ruled out completely.

If anyone is gonna do it, Honda would be top of the list! I could see a V3 as a flagship with a parallel twin of the 'front' two cylinders being the bigger seller maybe.

Do VFRs etc normally have the same cylinder head design front and rear? V3 is the worst of all worlds because it's two cylinder heads of different designs

Taking your logic: a single, twin and V3 as options, using just two barrels and two heads.

Part numbers of front and rear heads are different, so not the same design. In which case it's no different to all the generations of V4 engines they've made, requiring different design and manufacture for front and rear heads. It's only people like Porsche that try and make one head design work for both banks of cylinders (and look how that turned out).

So not really the worst of all worlds, but BAU.
