Microhybrids Are Big MPG Boosters, Report Says

Clean Edge, Inc., in its Clean Energy Trends 2013 report, cites the trend to microhybrids as one of the more positive and lasting movements in the transportation sector. While much attention is focused on electric vehicles and plug-in hybrids, the group sees microhybrids, also known as start-stop, idle-stop-go, idle elimination, mild hybrid or other names, as contributing more to increased fuel efficiency than any other technology.

The technology has been on the market for more than a decade and at least 40 percent of the new cars in Europe and Japan already use it, but it’s on its way to the U.S. as well. The attraction for the auto industry is that this is a relatively cheap technology that delivers tangible fuel economy improvements and helps them along the way to the goal of 54.5 mpg by 2025.
