Are there any hybrids which are purely IC-electric (like diesel-electric
trains) where there is no mechanical connection between IC and wheels,
just a generator and electric motors. This would allow all the
smoothness of acceleration that you get with an electric motor, because
the ratio between motor and wheels is fixed (maybe 1:1), so there are no
losses in a fluid flywheel or in the belts of a CVT. On the other hand,
petrol-electric-kinetic is more energy conversions so there may be extra
losses in that.

At first, I assumed that a petrol/diesel-electric hybrid was like this:
no mechanical connection, only an electric one.

I think Vauxhall did one but they don't sell them any more.
