  The original question was:
I would like to see a comparison of the extra energy it requires to produce the specific components vs. the equivalent measurement in lower fuel conception over a 5 year period.

I mine hard rock, not data. You made the statements, please provide the backup.

I have yet to see this information available anywhere. How does one convert vehicle “green” ratings for manufacturing a hybrid vs. conventional propulsion into energy usage? Then compare that rating or "unit" to the improved l/100 km reduction in pollution.

That is what those Green ratings are for.  Someone got the data and did all the work for most Joe-sixpacks.  The "so called" ratings just puts into an easier to interpret perspective.  Here's a short exerpt on what you see on that particular link:

A Yahoo! Autos exclusive, the Green Rating was developed in consultation with Environmental Defense, a leading nonprofit that finds practical ways to protect the planet. The Green Rating covers all the major environmental costs of a motor vehicle, including:

    * Unhealthy smog that comes from tailpipes.
    * Emissions of greenhouse gases that cause global warming.
    * The fuel a vehicle consumes.
    * Pollution from manufacturing the vehicle and its components.

Frankly, the unilateral and rather subjective stipulation for 5 years is something that you see a need for, and  it is only fair that you do that inferential work for yourself (or pay someone competent to do it).  As I stated previously, there's is no shortage of empirical information that those (governments and other organizations) who have done the studies can share upon request.

Cheers;

  Please read my question carefully. You have a command of the English language and it is impressive but please use it to formulate a response. The Links provided do not provide the information required.

Well I’m no Joe six-pack and a green number of 77 does not tell me the energy required to build a Ford Escape Hybrid vs. a non-hybrid powered Ford Escape.

The comparison chart indicates that the Hybrid produces 2908 less pounds of carbon dioxide, 2 pounds less of nitrogen oxide, 2 pounds less hydrocarbons, and 138 pounds less carbon monoxide in one year.

Hi H-IMA!

The animation in the World Honda site is very informative.  Thank you!
The 3-stage cam profile control of the I-VTEC engine is the key. At the low-load mode I think closing of the intake valves happens after the piston reaches at the bottom, thereby making the engine Atkins cycle in effect.  (Closing intake valves before the piston reaches the bottom will bring in the same result.) Developing an engine this complex costs a lot of money which only big companies like GM, Toyota and Honda can afford.  It involves many engineers designing, testing, re-designing, testing, redesigning, testing…. working overtime day in, day out.

The company who masters the technology of valve timing control will be the winner. Honda’s i-VTEC and BMW’s Valvetronic are only the beginning.  The next generation of technology will be electro-mechanical system using computer controlled solenoid or stepping motor.  “Displacement on demand” is good for ordinary engines, hybrids as well as for blown engines.

Have a nice day!

P.S. It is said elsewhere in this forum that “hybrid use a lot of precious metals”, but nickel used for to-day’s batteries and lithium to be used in the future are both not precious metals. Precious metals (platinum family) are used for the cat converters and hydrogen-to-electricity fuel cells (One of the reasons why fuel cell automobiles will not fly.)

why dont you(G35X,H-IMA)  start a new thread , or ask for a sub-forum for hybrid,
leave this one  for the Vue

I have thought seriously about a Prius. Was on my shopping list last time around. I love the design, the idea, the low emissions in electric-only mode, bodystyle, etc. It's very novel. I prefer a more involving driving experience with manual transmission (Honda did offer a manual, but in a less usable hybrid IMO) so went with something else, but will likely consider one again the next time around.

Civic only has a CVT, was that the last model will a manual?

Yes.
