Tesla Electric Car - sexy... nice...

The debate over the effectiveness of hybrid-powered vehicles at delivering anything other than lower mileage figures has just heated up. A US marketing company has released research showing that when you take the whole life costs of such a vehicle into account, they're not better for the planet after all.

Hybrid petrol electric vehicle advocates trumpet the environmental benefits of the petrol-electric vehicles, but, according to the results of an exhaustive two year study, the overall energy picture for hybrid vehicles isn’t as favourable as it seems. Oregon-based CNW Marketing Research said that, when the total cost of hybrids to the environment is calculated, including factors like original production and then recycling of batteries and electric motors, into a "dollars per lifetime mile" figure, hybrids come up short against conventional powered vehicles which where thought to consume more of the world’s energy.

"If a consumer is concerned about fuel economy because of family budgets or depleting oil supplies, it is perfectly logical to consider buying high-fuel-economy vehicles," said company boss Art Spinella. "But if the concern is the broader issues such as environmental impact of energy usage taking into account the energy needed to plan, build, sell, drive and dispose of a vehicle from concept to scrappage some high economy vehicles actually cost society more than conventional or even larger models over their lifetime."

CNW’s "Dust to Dust" survey studied hundreds of variables but to make it easy for the consumer to understand, developed an energy cost per mile driven figure. While some of the vehicles referred to aren't sold in the UK or Europe, the overall thrust of the research makes sense.

Topping the league with the most "energy expensive" vehicle from 2005 is the Maybach at $11.58 per mile, VW Phaeton at $11.213 and Rolls-Royce Phantom at $10.660 while the thriftiest is the Scion xB at the bottom of the scale, at $0.48 a mile, ahead of the Ford Escort at $0.568 and Jeep Wrangler at $0.604. However, the research brings into question the whole concept of hybrids as "energy-saving", at least for the planet as a whole.

The industry average of 312 vehicles was $2.281, yet all the hybrids cost more than this. Compact family hybrids like the Toyota Prius ($3.249) and Honda Civic hybrid ($3.238), cost more than a full size SUV Land Rover Discovery ($2.525) or Lincoln Navigator ($2.617). By comparison, America’s best selling car, the mid-size Toyota Camry, cost $1.954 and the similar Nissan Altima only $1.381. Hybrids on the other hand cost more over their lifetime due to the extra complexity and production and recycling costs: the Hybrid Honda Accord has an energy cost per mile of $3.29 while the regular version’s is $2.18. A regular Honda Civic costs $2.420.

"This study is not the end of the energy-usage discussion. We hope to see a dialog begin that puts educated and aware consumers into energy policy decisions," Spinella said. "We undertook this research to see if perceptions were true in the real world."
