« House Hearing on Hybrids | Main | About that CNW hybrid study »


David Pool

Has anyone -- manufacturer, scientific organization, anyone -- yet responded to the report that was issued earlier this year by CNW Market Research (which is really industry guru Art Spinella)? This two-year study concluded that, when considering the energy necessary to plan, build, sell, drive and dispose of a car from the initial conception to scrappage, hybrids cost more in terms of overall energy consumed than comparable non-hybrid vehicles. But even more surprising, it concluded that smaller hybrids' energy costs are greater than many large, non-hybrid SUVs.

I had assumed that once CNW released details on their methodology that there would be much critical analysis of the report...yet I have seen or heard nothing.


The CNW study was full of strange math and laughable assumptions. For example, it summarilly claims hybrid (Prius) will last only 100K miles while a truck will last 250K miles. It also included R&D cost and several other factors.

Strangely, Canadian Taxi companies using Prius as Taxi's reports 410K km. See link below.


I am not sure this CNW thing is worth the paper it is printed on. A real unbiased study would try to isolate all factors used specifically for hybrid and all comparable factors used specifically for conventional cars. It does not seem like that is what they did. This may be why no one paid it any attention.


Does the "miles" formula care what the purchase price of the new vehicle is? It seems like a more expensive vehicle would take more energy to produce (higher manufacturing cost, more labor/trips to the office for engineering, etc.)

I can see how the formula can get very complicated like investment analysis.

Great blog you have, i am doing a study on this subject and i fund some great information on your site

Thank you for that
