Hybrids like the Toyota Prius are selling like mad, but they are a stop-gap measure at best and the "misinformed craze" for them may delay sustainable technologies like hydrogen fuel cell vehicles, French researchers say.

Gas-electric vehicles are not environmentally sustainable, yet automakers like Toyota and General Motors are pouring tens of millions of dollars into them in no small part because consumers are convinced they are, Jean-Jacques Chanaron and Julius Teske write in "Hybrid Vehicles: A Temporary Step."

"There is a general convergence of strategies toward promoting hybrid vehicles as the mid-term solution to very low-emissions and high-mileage vehicles," the researchers say. "... Such a convergence is based more on customer perception triggered by very clever marketing and communications campaigns than on pure rational scientific arguments and may result in the need for any manufacturer operating in the USA to have a hybrid electric vehicle in its model range in order to survive."
