Ford To Offer Fuel-Saving 'Start-Stop' System 572

Posted by Soulskill
from the eventual-acceleration dept.
Ponca City writes "The Detroit Free Press reports that Ford plans to offer start-stop systems on many cars in 2012 that save fuel by turning an engine off when the vehicle is idling and quickly restart it when the driver releases the brake or steps on the gas pedal, improving fuel economy by 4% to 10%, depending on driving conditions. The system, common in Europe on cars with manual transmissions, is already in use in the US on gasoline-electric hybrids, including the Ford Fusion Hybrid. Automakers have been reluctant to add the feature to cars in the US because the testing method that the Environmental Protection Agency uses to determine fuel efficiency ratings doesn't include many stops and thus doesn't recognize the technology's effectiveness."
