I have to disagree with you on this one.
To me, it seems that no running an engine at its most efficient speeds,
as the hybrids do, and storing energy as electricity and using that in
such a way the efficiency is maximized will make a better combination
than cutting off cylinders.
Even buses in NYC use hybrid technology rather than disengaging
cylinders (or in addition to it). And the Swedes are working on hybrid
Plus, but using a hybrid design, you can have a smaller and lighter
engine than with an engine that has a variable number of cylinders. Of
course, the technologies are not mutually incompatible.

What manufacturer offers a V8 that gets well over 30 mpg?
OK, some V8 get close to 30 mpg highway, but none get even 30 mpg
highway, at least in the 2007 or 2008 model years:

It's a trade-off. Some people prefer a bigger car, some prefer one with
a smaller environmental footprint, which hybrids may or may not have (I
haven't seen a good accounting of the environmental costs of the
batteries and other technology).

Efficiency questions aside, another advantage is in packaging. You no
longer have to place the power steering pump, a/c compressor, etc, where
they can be driven by a belt from the engine; you can put it anywhere it's
Also, the belts and pulleys weigh something. Removing them helps offset the
increased weight of the electric motors you'll need.

Sorry, but if one makes a claim, it is up to the one making the claim to

Prius owner since January 1 here. The heater does indeed use the engine
heat as the heat source, no electric augmentation. We had plenty of heat,
and the heat came on as quickly as it does in my Jeep, which is considered
to be rather fast and strong. It does lower the gas mileage
See, whatever it needs heat for, it gets it from the gas engine. There is
no other heat source. This is why the gas engine comes on upon startup -
to heat up the emissions system so it performs optimally, then it shuts
off and is used as needed (sometimes only to reheat that emissions system
stuff in the winter).

they actually do. The Prius uses a thermos to where it pumps a good
percentage of the engine coolant when the vehicle is turned off (keeps it
warm for when the car is restarted without much of a delay). That is what
the whirring sound is at that point, and why there is about a 5 second
delay upon turn-on before the engine turns on (it pumps the fluid back
into the engine system). Once the car is running, it does not pump it to
that thermos, as the engine must reengage instantly when needed.
