There is a diesel Volkswagen that can achieve 50 MPG. My research reveals
that it is not for sale in California. Many of you don't live in Ca so this
is no concern of yours. Diesel fuel here in San Diego is more expensive than
87 octane gasoline. Unless you have a source for bio diesel, you may be in
the same situation.
Of course... Your mileage may vary.

It's also not for sale in any state that has the same emission
requirements as California. That's because the car can't pass the
It's also a smaller car than a Prius, with fewer features and options.
And around here, it's more expensive than 91 octane gasoline.

I see your points but I dont think I made myself clear. I'm interested
solely in C02 and am looking for the least polluting sensibly sized car
I dont mind paying for efficiency, but it seems that the diesel is "both"
cheaper and more fuel economic that the Prius
I love the Prius for its technology and probably being the precursor to a
cleaner environement(and hopefully nuclear powered if the public perception
is open minded enough) and a faster track to hydrogen
Now I see the reality in the fuel consumption, its got a long way to go and
I'm a little sad about this. I did leave a thread last week about the
weight/safety issue and this too still has to be addressed. Again i dont
mind sacrificing other budget items to pay for this.

Be aware *all* cars suffer the "real world" losses in fuel economy the Prius
does. A significant part of every tank of fuel goes into something other
than covering miles: heating or cooling the occupants, keeping lights lit.
In conventional cars a lot of fuel is burned at zero mpg, waiting in
traffic. Today's hybrids control that part well.

Right. A round trip from point A to point B and back will consume a
certain amount of fuel, be it gasoline, propane, diesel, or
electricity. ALL of the energy released by the propulsion process in
using up that amount of fuel ends up as waste heat (internal energy)
discharged to the atmosphere. That's the price we pay for moving our
butts around the planet.
The trick is to maximize or optimize the efficiency of the conversion
process (energy to work) and keep parasitic losses, such as excess
weight, tire friction, internal engine friction, electrical losses,
pumping losses and air drag to a minimum. That is, very simply,
strive for the highest MPG possible.
The Prius, by using a small engine with electric motor boosts as
needed, stopping the engine instead of letting it idle when the
vehicle is stopped, and utilizing regenerative braking has shown the
way to go. I think it is definitely the wave of the future made
possible by computer control.
By the way Robin, forget hydrogen as a significant replacement for
petroleum based fuel. Ain't going to happen. One man's opinion, but
I know a lot about what would be involved in attempting that. There's
no good answer for replacing petroleum based fuels. We're in an
