Michigan Researcher Claims 74 MPG by 2035 is Highly Possible

According to an article in hybridcars.com today, John DeCicco of the School of Natural Resources and Environment at the University of Michigan claims that an average fleet fuel economy of 74 MPG is highly possible by 2035, and would not involve plug-in hybrids. Instead, he claims that significant improvements can be made to combustion engines as well as the introduction of non-plug-in hybrids. While trendy and receiving support from lawmakers, plug-in hybrids are not nearly as cost-effective as existing technologies, and have limitations that make them less desirable to American consumers, whereas in DeCicco's scenario, "creature comforts" would be maintained.
