I'm not surprised that some of you favor Diesel engines. But diesel fuel IMHO should be reserved for boats, trains, and tractor-trailers. The only reason Diesel is big in Europe is because Gasoline is taxed through the roof while Diesel is not and Gasoline cars are still fairly common over there despite that. The Diesels having trouble passing American emissions is just a red herring.

HCCI engine, now you're talking, GDI too.

As you guys may have guessed from my subname I'm a big Ethanol supporter, which is here now and made from Corn. But I am realistic in that I know we can support 33% of our Petroleum consumption with Domestic Oil and we should be filling the rest of that gap with Ethanol or Battery Electric cars not foreign Oil. I don't rag on hybrid cars that do their job. And I do rep good hybrid cars. Electric cars that are fun and efficient are cool too. But I also support Mandating Flexfuel, designed to run safely and efficiently on 100% Gasoline or 100% Ethanol(some us even ask for 100% Methanol which is like adding $30 to a $100 upgrade) for all vehicles in the USA. Not mandating that everybody drive on Ethanol, just that we require all vehicles be Flexfuel compatible before they can be sold.

Hydrogen doesn't work for the same reason Natural Gas doesn't. Both need to be either pressurized to super high pressure levels at normal operating temperatures, or frozen at below zero, or for Hydrogen mixed with another element in $$$$ special fuel tanks. Plus Hydrogen is cracked from Natural Gas just like Methanol. Not an ideal system if you could just use the Natural gas right? If you want a system based more on the politics/emotions of zero emissions at the tail pipe when there is a stink cloud somewhere else, Hydrogen is your answer.
