RAND PAPER FINDS DIESEL- AND HYBRID-POWERED VEHICLES CAN PROVIDE MORE SOCIETAL BENEFITS THAN GAS-POWERED AUTOS
Cars and light trucks powered by advanced diesel technology or hybrid technology can provide larger societal benefits than traditional gasoline-powered automobiles, according to a RAND Corporation working paper presented today.
The research by RAND, a non-profit research organization, also found that light trucks and cars continuously fueled by a mixture of 85 percent ethanol and 15 percent gasoline known as E85 compare unfavorably with the other two alternatives.
Rising oil prices coupled with concerns about global climate change are driving debate about which fuels and engines should be used to power the 17 million new cars and trucks sold each year, said John Graham, dean of the Pardee RAND Graduate School and senior author of the research paper.
Advanced diesel and hybrid technologies show very well in this study, in terms of benefits to the individual and society overall, Graham said. E85 simply doesnt provide the same benefits.
Graham presented the results of the research today at the annual meeting of the Association for Public Policy Analysis and Management in Washington, D.C. The peer-reviewed paper is available online as part of RANDs working paper series in which initial research results are shared publicly to solicit additional technical feedback.
The research examines the benefits and costs of three alternatives to the gasoline-powered internal combustion engine for the 2010-2020 period: gasoline-electric hybrid technology (as found in the Toyota Prius or the Ford Escape SUV Hybrid), advanced diesel technology (such as the Mercedes-Benz E320 sedan), and dual-fuel vehicles that are powered continuously by E85.
Each alternative has the technological potential for significant market penetration in the near term, the research finds.
Additionally, each technology was c
