Yes so why aren't you facilitating and advising me when I ask simple questions? I am not close minded I have switched ideas several times. Just because I don't want to go down the Flat engine route doesn't make me close.minded.

Umm they do a better job at all of that then anything else... Is there any specific problems that will cause excess heat or make it difficult to get rid of it? V and W configurations are more compact then flats and inlines, meaning they fit better too. Is there any specific reason as to why a V or W is not as safe as say a flat 6 under the rear seats.
It seems to me that for all your claiming that I am close-minded you are the one who is singularly pursueing a flat engine configuration, even when I give valid reasons why it isn't what suits this application best.

I haven't asked you to solve anything I asked you to present your obvious objection to V or W configuration engines in an orderly and presentable fashion so that I can see what you want solved. So far the only advantage a flat engine has is that it has a slightly lower CoG. That just simply isn't enough to warrent all the hard work that will be needed to solve the myriad of other problems a flat configuration has.
And I am sorry Matra but I didn't think it was a confortable car to be in (I haven't driven one I have only been a passenger in the front because my 6'10" frame doesn't fit in the back.)

WHY are you mounting them "off the engine" ?)
Mount it above the diff for examples -- assuming a racing transmission layout with gearbox to the rear and diff mid mounted.
That took me 5 seconds to solve on reading your negativity.
You can achieve the same and improve on your own ideas and absorb others with positivity and reality.
Yes but one of the first things to think about is "Is this worth it?"
Wow Matra I am impressed you have solved the problem so easily
Just a few problems you have at least an Alternator, A power steering pump (which could be electric), Coolant pump (could also be electric), and AC pump (most likely not electric) You can't mount all of that in a small place. The Alternator needs to have a good deal of mechanical energy put into it and the best place for that is belt drive off the crank. Yes you could mount it somewhere else on the drivetrain but you need the speed of the crank (otherwise the pulley/gear ratio gets too high) the AC pump needs alot of mechanical power too but it can be mounted on a slower speed part of the drivetrain so yes for the AC pump the differential would work. If you make Power steering and Coolant pump electric then the alternator has to be larger.
I had another idea that might be interesting: since TEGs normally have ceramic plating on both sides you could in theory line the cylinders with them. This way you could use some of the heat that is lost to the cooling system to generate electricity. If enough could be made it could replace the alternator all together and drive all other ancillaries (except maybe the AC pump). It would also reduce the thermal capacity needed in the cooling system, meaning a smaller lighter cooling system.
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.
