Actually, putting the laptop beside it gives a better impression of scale...

Hm that last pic is quite helpful; it's not as tall as I thought.

 

Though it is very tall in proportion to width/depth. Still wondering about how they're planning to package it in the car.

Well at the very least they'll have to unzip the top of that laptop case, because otherwise the induction gear won't fit.

It is considerably smaller than I envisioned.  A 400hp backpack.

I can imagine that shoehorned into a 100kg laydown kart with ground effects aero and setting absolute lap records all over the place.

I may be missing something here (and I mean that seriously) but this engine appears to me to be just a bloody engine. There doesn't seem to me to be any revolutionary feature of this engine that makes it really different from any of the well-known 'bike engines (such as the Hayabusa etc.). A Hayabusa engine weighs 70kg with gearbox/clutch etc. - a 'Busa built with no g'box etc. would probably weigh little different to this engine.

Am I missing something?

Doubtful. And the 'bus engine isn't even abnormally light for its capacity.

 

But if Nissan can make it last the whole 24 hours I shall be impressed indeed.

 

edit: BMW's ~1650cc inline 6 is reportedly 103kg with gearbox. I am somewhat surprised by this, thought it'd be a bit lighter.

I will be impressed if it lasts 24 hours as well. The point I am trying to make about this engine is that it appears to have nothing revolutionary in either its construction methods or the materials used. If it is notably light it is probably because it lacks necessary "beef" in certain areas.
The rubber cam belt also seems to be an slightly odd choice for a specialised racing engine.

...the chassis the engine goes in.

I'll ask a peripheral  question about the chassis  shown above.

 

Why, oh why is the driver installed with his feet up in the air when there appaers to be a large space below his feet before you reach the chassis floor?

 

 

It might be some  subtlety I've missed - OR it might be because al F1 cars look like that so these designers just copied F1 even though you could improve the C of G and the driver ergonmics by placing his/her heels down on the chassis floor.

Probably to give the driver more support when you brake. Less movement, more control. Its also a decent place to put some electronics, batteries++ who might be heavier than some big space and a pair of feet.

 

Even if you force flatt underside rule on F1 cars the drivers would probably be sitting somewhere close to how they are now. Its 5G+ after all.

very impressive. raised driver and foot for some clever airflow maybe? some heavy mechanisms maybe mount beneath driver's feet

Also interesting that they appear to have the engine mounted east-west. Rather unusual for a pure prototype, but with an engine that small I suppose it makes a lot of sense, packaging-wise

A very neat-looking design - they just need to move the front wheels back a few feet and add a lot more spacing between them. The steering wheel/driver's arms positioning looks very NASCAR-ish and uncomfortable.
As for the driver's feet - this:

seems to show the pedal position as conventional.

 . . . . and restore the missing beef to certain areas of the engine?  (silly Nissan)

You don't even need ignition if you fit a horse

yes, think the ZEOD is so compact it needs space for packaging but that see through of the AUDI looks nice

I wonder what the power figures would be if it was a normally aspirated engine?

The engine is clearly designed for turbocharging and endurance racing duty (eg 7,500 rpm), so its NA output is not really relevant, but at a guess - 200 bhp assuming CR, cams etc were re-optimised.

 

If they were designing a 1.5 litre NA endurance engine from scratch it would have more cylinders and have an output in the 300 bhp range at 12,000+ rpm.

It's a nice piece of kit.  If only they would put it into a real car instead of that wheelbarrow.

you obviously have never seen a 400hp wheelbarrow.

That's being a little unkind to wheelbarrows.
