Ford Brings Fuel-Saving Auto Start-Stop Technology to North America in 2012
December 2010 — Dearborn, MI
Ford Motor Company announced it would roll out its auto start-stop system to gasoline-powered cars, crossovers, and SUVs in North America by 2012. Already popular in Europe, this fuel-saving technology helps improve mileage by automatically shutting off the engine when the vehicle stops—such as at traffic lights or in stop-and-go traffic.
Then, when the driver lifts their foot from the brake, the engine restarts instantly. This smooth, nearly invisible feature saves fuel, reduces emissions, and enhances driving efficiency—without changing how the car drives.
Proven Technology with Immediate Impact
Ford has already used start-stop systems successfully in Europe and Asia, primarily on diesel and hybrid vehicles. However, the North American launch marks the first time the company will bring the technology to conventional gasoline models in the U.S. and Canada.
Because the average driver spends a significant amount of time idling in traffic, the potential for fuel savings is real. Ford estimates up to 10 percent better fuel economy in city driving—without any need for driver input or special operation.
How It Works
The system is simple yet smart. When the car comes to a complete stop, the engine shuts down automatically. Meanwhile, all essential functions—such as the air conditioning, radio, and power steering—continue running on battery power. Then, as soon as the brake is released or the accelerator is pressed, the engine restarts in less than a second.
Ford’s start-stop is engineered for seamless restarts. In fact, most drivers may not even notice it’s there—except at the gas pump.
Part of Ford’s Broader Green Strategy
This move is part of Ford’s broader sustainability plan. The company had already committed to improving fleet-wide fuel economy by investing in EcoBoost engines, hybrid systems, electric vehicles, and lightweight materials. Adding start-stop tech complements those goals.
Even better, Ford planned to keep costs low. The start-stop system would be relatively inexpensive—adding minimal cost compared to the potential fuel savings over time.
Why It Matters
As fuel prices rise and emissions standards tighten, automakers must find creative ways to reduce consumption. Ford’s decision to implement start-stop on mainstream vehicles shows that innovation doesn’t always require radical redesigns.
Instead, small, smart steps—like shutting off the engine at red lights—can lead to big changes. By 2012, millions of Ford drivers could benefit from a technology that saves fuel, cuts pollution, and demands nothing in return but a tap of the brake.
