The IC engine is only about 25% to 30% efficient so even generating
with say, 85% efficient fuel use may help overall.

Apart from fuel cells which can be higher than ICEs, what fuel did you
have in mind to have 85% efficiency?

Not so much the fuel but what burns it to power the generator.* Some
boilers can be that efficient.

Lets stop there. Are we talking of boilers or fuel used in association
with prime movers? They are world apart.

I can also assure you some boilers are far higher than that.

Electricity has relatively little loss
getting to the end user.* If you use oil to run a boiler at 85%, lose a
little in transmission,

What has a boiler got to do with this?

the car may be operating at 80% of the energy
instead of 25%.

I really suggest you lookup Carnot and the Second Law of Thermodynamics
before mentioning boiler and transmission in the same sentence. This
might assist in a more complete understanding of thermal engines:

and
https://en.wikipedia.org/wiki/Carnot_heat_engine

which explains why power stations are rarely much above 40% efficiency,
and that is before electrical power transmission, charging regimes for
batteries, motor and transmission efficiencies as well as lugging a
tonne of batteries around.
