BigMcLargeHuge,

You state: "you were wrong about mixtures, Prius acceleration, the 5-10% advantage, complexity, and the OPEL example"

Sorry BigMcLarge - I am correct:

Getting the correct air/Diesel mixtures really is a an issue in Diesel. Really.
Guess why a Diesel engine costs more than a gasonline engine. That is for the additional complexity - not just for fun. Since they sell as many gasonline as Diesel engines in Europe the addional margin is not just because of fewer mass production. Go to the resective web site and check out prices - please.

The "Opel" example - by all means - is correct. Again, what matters is not the mpg - what matters is the production of CO2. It is simply not correct to go by mpg when at the end of the day the CO2 matters. Oh yes, and please add the addional consumption that the clean Diesel needs. There really is no advantage left - at least at the current state-of-the-art.

The Prius acceleration: Indeed is really good - Diesel might be better. Here you might be correct.

The statement, that an electric or hybrid car is comlex is simply nonsense. So far they are based on reasonably known electric machines with very few moving parts. They will get much better and complexer in the future - sure. Also, they have some complexity in the electronics and software. And indeed, momentarily Hybrids are more expensive - but that is largely due to the prices of batteries not for complexity.

To combine the Diesel and Hybrid into one might indeed be the best solution. Well, let's hope we can pay for it. And, yes, a Diesel engine needs the correct engine temperature to work best - so it is not clear to me if one can switch off the engine and drive electrically every now and again with a Diesel without too much Diesel dust.

I guess, I have to stop the discussion now. Since there are other duties waiting for me. Was fun though talking with you.
