With increasingly stringent mileage standards coming down the pike over the next decade, automakers are frantically racing to find ways to boost the fuel economy of their vehicles. Some new features would yield benefits that are barely measurable, others could add significantly to a vehicle’s price tag. But new Stop-Start engines are delivering significant mileage benefits, often without additional cost to consumers.
A new study suggests that Stop-Start technology – which shuts an engine off, rather than idling – can reduce fuel consumption by anywhere from 5% to 7%. And it achieves a similar reduction in the production of global-warming CO2 emissions, according to research by the AAA.
“Up to seven percent improved fuel economy can mean a $179 annual fuel savings* for consumers,” says Greg Brannon, Director of AAA’s Automotive Engineering and Industry Relations team. “The technology requires only minor adjustment for motorists – automatic stop-start technology is simply applied to standard combustion engines.”
