Why do you endorse these fraudulentt claims?
Range with part of the energy coming from an initial charge
does not have anything to do with MPG.

Yes it does. It all counts towards getting the most empg out of of
whatever fossil or synfuel, and thereby contributing the least per
mile CO2 and NOx into our badly polluted environment. It's a win-win,
not half bad looking and affordable.

You should see the car I'm designing. It will get 3,750 MPG and
deliver over 500 horsepower. It it self-cleaning and the Limited
Edition will cook dinner for you. Concept pictures coming soon.

These vehicles aren't fantasy pipe-dreams. There are already a number
of companies and individuals who will convert a Prius to Plug-in Hybrid
Electric (PHEV), and Toyota is currently road testing a production
version.

The MPG claims are not as straight-forward as with other cars, because
actual mileage will differ drastically based on driving habits. If
someone did a daily commute within the electric-only range, then they'd
never use gas, and the MPG would be infinite. Though if you took a
cross-country trip without plugging in during the trip, the MPG would be
the same as a conventional hybrid. No doubt the marketing folks used a
scenario of a 'typical' driver to come up with the 250 MPG number, but
it doesn't make it unrealistic, nor does it mean these cars aren't a
significant step forward.

Yet, the electricity that they use requires the burning of fossil fuels,
unless it came from renewable resources, like solar power.

So effectively, the lower gas mileage does a lot to make people feel
good, but doesn't really reduce greenhouse gases.

Does the zero gas mileage take into account the amount of fossil fuels
needed to make the batteries, not to mention the tires, engine and rest
of the car?

Over the road travel the Generator will use 1- 1.5gal of fuel per
hour.... at 60 mph thats still only ~60 mpg... on a 10 hour trip you
only get the first 30 miles or so on the over night charge.

Does the mileage estimate for a conventional car include the energy
required to make it? The hybrid batteries don't require any
extraordinary amount of energy to manufacture.

Electrical generation and transmission is much more efficient than an
automotive ICE. And it can be practically be generated from renewable
sources like wind and solar.

The major problem with plug-ins (whether hybrids or pure electric) is
the batteries. In a conventional hybrid, the batteries are never
charged or discharged outside of a relatively narrow range, say 50 to
80% of capacity. Used in this manner, the batteries last a long time
- maybe the life of the car. If a plug-in is to achieve maximum
efficiency, it will be charged up to 100%, then discharged to near
zero. Such use greatly decreases the life expectancy of these
batteries. When you add in the fact that a plug-in is likely to carry
a lot more battery capacity than a conventional hybrid, the battery
cost over the life of the vehicle may not be economically viable.

True, although 60 mpg isn't bad. The big savings comes from the fact
that most cars are driven only 30 to 40 miles per day starting at and
returning to home where they could be charged overnight. If most of
your driving is 10 hour trips, a plug-in probably isn't a good choice.
