Ford is offering the Auto Start-Stop system on its new non-hybrid 2013 Fusion equipped with a 1.6-liter EcoBoost engine (earlier post) for $295. Auto Start-Stop saves fuel use when the car is standing and running at idle. Savings vary depending on driving patterns, but owners who spend most time in heavy urban areas and city traffic will benefit up to 10%. On average, Auto Start-Stop improves fuel efficiency by about 3.5%.

The Ford Auto Start-Stop system includes a 12V battery designed for long lasting service with no additional maintenance; a 12V enhanced starter motor to provide seamless engine starts once a driver removes his or her foot from the brake pedal; and a voltage quality module to assures vehicle accessories function normally when the engine is off.
