Stop/start technology saves on fuel, AAA research shows
Automatic stop/start technology provides a 5 to 7 percent improvement in fuel economy and carbon dioxide emissions, according to new research by the American Automobile Association.
With an automatic stop/start system, when the engine is stopped, systems and gadgets run on power from the car battery. The feature most often deploys in city driving.
AAA put three automatic stop/start vehicles through the Environmental Protection Agencyês urban cycle, which simulates a commuting trip covering 11.04 miles at an average speed of 21.2 mph. The cars tested were a 2013 Ford Fusion, a 2014 Mercedes Benz CLS550 and a 2013 Chevrolet Malibu.Download Bulletin PDF
