I think that is overstating it a bit, and I expect it won't be too long
before the batteries are replaced with capacitors.

In any case hybrids as we know them now are a sort of transitional
technology, much as turboprops were the transitional technology between
piston powered planes and true jets.

Once the automobile becomes a mature technology I expect they are going
to have hydrogen fueled fuel cells driving electric motors (in the case
of Jeeps there will be one motor per wheel).

It may be that those vehicles will have battery or capacitor packs much
like todays hybrids have, the hybrid technology is really an electric
flywheel and a big energy flywheel (like a big cache in your computer),
will make it function more efficiently.

While the basic CRD technology can handle biodiesels in principle, in
practice current CRDs are very fuel-specific. They like a fuel that
amounts to a more lubricious and dense version of Jet A. No such fuel
is available in the US, and both VW and VM CRDs are having a lot of
fuel related issues.

Mechanical diesels are much more fuel agile. The most agile, besides
purpose desgned military multifuel engines, are prechamber engines with
Bosch inline injection pumps. Two cycle DD engines are also relatively
unfussy. Large Cummins engines with PT injection are okay with a lot of
fuels as long as lubricity is good or you fit the hardened pump and
injectors.

It will be a long time before US diesel meets First World standards,
because the powerful truck lobby wants cheap diesel fuel. Eisenhower
built the Interstate system for national defense, but by letting trucks
undercut the railroads it destroyed transportation efficiency in the
US.
