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. Utilising 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. 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.
