Today's Prius can already do 60 MPG on the highway, while the
engine is not running in its optimal point; having the serial
hybrid setup allows you to tweak the engine to run at its best
performance and send all extra to the battery, once the battery
is sufficienty charged (say, up to 50% from 20 or 30%) then the
engine can stop entirely for another 10 miles or so EV-only
drive, then the engine can again be run at its optimum efficiency
and besides, they did not make a claim as to which *speed* they
were running at. I bet it is possible to run the Volt at 100 MPG
by choosing a low enough speed, just like Prius hypermilers can
achieve 100+ MPG by investing enough time (among other optimizations)
Luckily the proof of the pudding is in the eating, so all we need
to do is test it.... I'll go to my GM dealer and see if I can
arrange for a test drive to compare it with my Prius and my EV ;-)
Serious though - I get the strong impression that GM is aware that
it is either going to make the Volt a success, or fail completely
and disappear in the margin, so there is enough pressure on getting
the Volt to the market already.
Besides, the facts seem to indicate Peak Oil was last year, so
there will be no more concern about global warming soon.
Only about who gets the oil supply that is left.
Today: about 80 million barrel/day. In 2030: half of that.
(a decline of avg 3% per year).
So, there is little time left to change the consumption, as
the supply will unfortunately be setting the stage (and price).

I have my doubts that a car of that size and aero profile is going to get 50mpg on gas alone. It's just a really optimistic guess on GM's part right now.
----- Original Message ----if you are on a long trip then 50 mpg.
