A University of Michigan researcher says it's possible to triple(使成三倍) fuel economy in gasoline-powered cars by 2035, but it'll mean getting our automotive kicks from smart electronic technology and other forms of virtual performance rather than horsepower. As federal regulators are poised1 to(信誓旦旦,准备就绪) propose the next round of fuel economy mandates2(授权,命令) , John DeCicco, a senior lecturer at the School of Natural Resources and Environment and faculty3 fellow with the Michigan Memorial Phoenix4 Energy Institute, says the most cost-effective answer is steady progress in advanced combustion5 engines(内燃机) and hybrid6(混合的) drive---but stopping short of plugging in and requiring super batteries or gaseous7 fuels(气体燃料) .

He finds that the solution is in our garages if Americans shift gears in terms of priorities. What DeCicco calls a "revolution by evolution" avoids politically trendy breakthrough technologies that will remain too expensive for most consumers.

"If we really prioritize efficiency, we can get just as far with less sticker shock," he said. "Evolutionary8 change can be of profound consequence for cutting oil use and greenhouse gas emissions9, and do so with manageable costs and minimal10 risks for automakers."

DeCicco has completed a study for The Energy Foundation examining how far fuel economy can be taken if it becomes a top priority in product planning.

His analysis shows that optimizing11 internal combustion engines(内燃机) plus rising adoption12 of grid-free hybrids13 will enable new fleet efficiency to reach 52 mpg by 2025 and 74 mpg by 2035.

Reaching such a horizon would entail14 cultural change in a gearhead(计算机迷) world attuned15 to(习惯于) nuances(细微差别) of power performance. DeCicco identifies emerging trends for what he dubs16 "efficiency compatible" design strategies, enticing17(迷人的,引诱的) buyers away from brute18 force and toward smart technologies, intelligent safety features and svelte19(苗条的,和蔼的) styling. Amenities20 like Bluetooth hookups, communication bandwidth and other information technology enhance customer value with minimal demands on power.

The report develops new interpretations21 of technology cost estimates that better depict22 the benefits of ongoing23 innovation while acknowledging the limits of how much consumers can spend. The analysis reflects the three-way trade-off among efficiency, performance and cost that the car market is likely to face in the years ahead.

"The fleet I've modeled for 2025 does not give up any of the performance and creature comforts consumers already enjoy," he said. "You don't have to go back to being Fred Flintstone, but you will see lower fuel costs instead of ever more mass and muscle."
