Which ones meet the technical qualifications of "high pressure direct injection and turbo charging?"

Check out the Jeep, which according to the EPA, has no turbo charger.
Does the Jeep sell in CARB states?

That is true. Vice-versa, hybrid advocates often brag about the Urban mileage ("the prius gets 60mpg!"), as if they think everyone lives in downtown New York or L.A.

My insight hasn't even set foot inside a city. Not once.
It's urban mileage is irrelevant for this driver.

There needs to be a balance when presenting information, because some stats simply do not apply to all people. BTW, 70mpg is the Lupo's combined MPG. When it was still available, it was listed as 88mpg highway (higher than any other car) and 62mpg city (about the same as an insight) on the official volkswagen.de website. Wrong Car. The Lupo 3L/70mpg car has a 1.2 liter engine, not 1.4.

Here you go: Link: http://transtech.anl.gov/v3n3/greet.html - One of the cars listed is:

ICE HEV LSD - intenal combustion engine - hybrid - low-sulfur diesel

which uses less energy than a gasoline hybrid. As you'd expect. A diesel engine runs at close to 60% efficiency while a gasoline engine peaks at ~45%. Thus the diesel hybrid not only pulls more work out of each BTU of energy, but also has the benefit of a EV mode for city driving. It is the best of both worlds:

- an EV mode for city driving (like a prius)
- a diesel mode for highway (very efficient -same mode used by long distance trains & trucks)

As with many of Bob's threads, this one was looking like a pretty good read until it reached a low point. Let's remain factually objective and cordial, shall we?

Make? Model? I would like to test drive one. In fact, it is just a 'model', not a real car, and many of us would welcome a diesel-hybrid. GM had in 2000 a concept car called the "Precept" that would have been a Prius killer had it been produced. But sad to say, the production model, the Volt won't be here until 2010.

BTW, you may want to cite a source for your thermodynamic efficiency numbers for automotive diesels. As a general rule, throttled operations tend to decrease efficiency significantly.

BTW, I was looking for something else and came across John's guidelines for dealing with hybrid skeptics:
