An anonymous reader sends in a story from Central Connecticut State University, claiming that a Prius takes more energy to manufacture than a Hummer — 50% more. In addition, the article claims that the Prius costs $3.25 per mile over its expected lifespan of 100,000 miles compared to $1.95 per mile for the Hummer. The article gets its data from a study by CNW Marketing called Dust to Dust, which is an attempt to account for all the costs of vehicles, from manufacture through operation through repair and disposal. The $3.25/mile cost quoted for the Prius is the 2005 number; for 2006 it is $2.87. This improvement pulled the Prius below the straight industry average — all the other hybrids are still above that average. And the Hummer is not listed at all for 2006.
