3Q 2012 (Pike Research/Navigant)
“During the past decade, driven largely by an effort to meet legislated carbon emissions reduction goals for vehicle fleets, automakers have introduced technologies that enable internal combustion engines (ICEs) to turn off automatically when vehicles are stopped… “…[S]top-start vehicles are also known as micro hybrids, idle stop vehicles, and a variety of names branded by automakers, and in many cases the technology is bundled with other fuel efficient technologies. These vehicles can offer significant reductions in fuel consumption and CO2 emissions, although the actual savings depend heavily on the drive cycle.”

With the most aggressive environmental goals in the world, Europe has seen by far the greatest selection of vehicles with stop-start technology and, not surprisingly, the greatest volume of vehicles sold… “North America has experienced a relatively slow penetration of the technology due to less stringent emissions reduction goals and an Environmental Protection Agency (EPA) testing cycle that underestimates the benefits of the technology. Worldwide, Pike Research expects more than 41 million of these vehicles to be sold annually by 2020 – nearly a tenfold increase over 2012 sales…”
