Start-stop engine technology, made possible by advanced lead batteries, reduces fuel consumption and emissions by stopping the engine when the car comes to a full stop, and seamlessly restarting when the brake is released.
When the engine is off, start-stop lead batteries save fuel. This can yield fuel savings ranging from 3 to 10 percent depending on driving conditions. Utilizing this technology is one of the most affordable ways for drivers to cut fuel use and greenhouse gas emissions.
Start-stop technology will be prevalent in most cars over the next few years. Ford aims to transition 70 percent of its vehicles to this technology and in 2018, 100 percent of new Buick models will employ start-stop technology. Between 2016 and 2020, the market for start-stop enabled vehicles will surge from 25 million to 65 million vehicles in North America, Europe and China.
