BarefootMatt is right. As a matter of fact Norway has reduced taxes on diesel vehicles because they emit less CO2, making diesel versions of the same car cheaper. They are more concerned with CO2 emissions due to greenhouse effet concerns.

Sorry guys. I'm pretty sure the Prius beats any diesel fueled vehicle that can carry 5 people in distance traveled per litre of fuel consumed. Add to that the fuel it burns contains less carbon, and you have reduced your carbon footprint a lot! Prius is at the top of the EPA fuel economy list, now that the Insite is no more.

What I was getting at is a diesel hybrid would still emit more CO2 per "standard distance" than a Prius. You could argue I'm wrong on this, but go ahead and prove it. ;)

The Prius does 105g/km.... What other comparable diesel car comes close?

Sorry, I should have pointed out that the OP was comparing a diesel car to the Prius, not to a non-hybrid car. That's what I have been considering when commenting.

As far as the Norwegian Govt., I think they should consider a different tact. They should be encouraging -any- technology that reduces CO2, not specific ones. Reward any design that reduces CO2 by an amount comparable to the reduction. Choosing one technology is going to lock you in to something that could turn out to be wrong!

I maintain that a diesel hybrid would emit less CO2 than a gasoline hybrid. If the principle applies to conventional cars, why should it be any different for hybrids? I'm not arguing the point that the Prius has lower CO2 emissions than any conventional diesel car, but you have to recognize that conventional diesels do better than conventional gas cars, so it stands to reason that a well-designed diesel hybrid could be more efficient than the Prius.

Toyota is considering pairing the Hybrid Synergy Drive w/ a diesel:

I personally don't care wht the technology is, as long as it gets me from point A to point B the quickest and most efficient way possible. . . .

Now that's a car I would buy. Of course, with the premium we pay for hybrids added to the premium we pay for diesels, a diesel hybrid would likely end up being more expensive than either.

TROLLS!

Gas mileage: in overall driving situations, the Prius beats the mileage of any diesel--TDI, Smart Car--and it's a bigger more roomier car.

The Opel Vectra is a very roomy car

Environment: NO comparison. PZEV beats ULSD. Although I can't find a source, I would guess ULSD will be merely as clean as conventional gas vehicles (definitely a welcome improvement), making PZEV 90% less polluting.

Sorry, but your guess was wrong here.
Thanks to its higher energy content and its efficient combustion process, diesel performance enables cars to travel at least 30% farther on a gallon of fuel than comparable gasoline models.

".....The Accord Diesel (using petroleum diesel) offers the lowest fuel consumption and the lowest CO2 emissions, even surpassing the Accord Hybrid."
"Comparing the i-CTDi and the EX highlights some of the efficiency and benefits of the diesel platform. Although the gasoline engine is slightly larger, the diesel offers incrementally better acceleration (due to the greater low-rpm torque), 33% better fuel consumption and approximately 25% less CO2."

One great possibility: a hybrid that's ULSD.

Absolutely! There are already 80mgp diesel hybrids in tests in Europe.


In conclusion, the above does not weigh the pros and cons and is therefore one-sided. I maintain that hybrid technology is a worthwhile transistion toward clean forms of transportation.

It becomes extremely interesting, when diesel production from regrowing materials become available (no biodiesel; already offered in Europe). Because then real "carbon neutral fuel" will not add CO2 to the environment anymore. I think this is even better than hydrogen, because the production of large amounts of hydrogen and the missing infra structure are still a problem.

Per, 150mph is correct. You can do that kind of speed on the autobahn. You just have to find the right stretch.

No, I had liter indication and converted it at 3.785 gal per liter.
