In California, you would have a hard sell of any turbo-engine diesel as
CARB's (California Air Resources Board) pollution standards pretty much rule
against them in terms of pollution.  Diesel generally costs more in
California than more refined gasoline as they want the air cleaner (less
sulfur compounds) than diesel provides.

Placing a same "miles-per-gallon" diesel verses a same "miles-per-gallon"
Prius in California wouldn't fly with CARB - ruling out vehicle cost.

That's interesting, thanks.  In Europe there are relatively new "Euro IV"
(i.e. Roman 4) standards for diesel emissions (my new Skoda meets them) and
version V (5) is on the way.  Very low (essentially zero) sulphur fuel is
readily available (in fact I think it's all you can buy on most forecourts)
and we have particulate traps for soot.  What do California's trucks & buses
run on?

Most of our buses here in San Diego run on natural gas (CNG ).

Quoting from page 203 of the US 2004 Prius Owner's Manual, Section 3
"Information Before Driving Your Toyota," Fuel section:

"Toyota allows the use of oxygenate
blended gasoline where the oxygenate
content is up to 10% ethanol or 15%

So, you're fine with E10, but nothing higher.  The Prius is NOT a
Flex-Fuel vehicle.

A short term study of E85 on a Classic Prius found reduced fuel
economy, some higher emissions, and a check engine light, but no long
term study has been done.  (Ethanol is known to break down some
components of the fuel system and engine if a car isn't properly
designed to run with high concentrations of E85.)

If the Prius were flex-fuel capable, we could all have more options for the
fuel we consume. Weather the ethanol were generated from sawgrass or corn.

I would like to see future models configured for flex-fuel. I would also
like to see our country work toward low sulfur bio diesel options as well.
With the success that I have seen with my '05 Prius, Any of these options
would be an improvement to E10 that we have now.
