Auto stop-start technology: a layman’s understanding

The auto stop-start was considered fancy tech when it was first introduced.

Recently, even the more economical cars like Perodua’s Axia and Proton’s Saga have adopted this technology to appeal to the masses.


There’s more to it than just being a ‘cool way’ to start your car.


A car’s auto stop-start system automatically kicks in when the car is stationary in order to reduce fuel consumption and emissions. When the engine RPM senses that it has fallen to a full stop and the driver has engaged on the brake, the engine turns off  and restarts once the brake has been released and the driver accelerates.


Ideally, you would not only save money with this system (albeit just a small percentage difference), but it is also greener for the environment.


But the question many may be pondering upon is whether or not the stop-start feature affects the engine over time. 


The general understanding is that cold starting your engine (EG: starting your engine after several days) takes a negative toll on the engine.


Auto start-stop engines will damage car batteries. Yes or no ...

However, this is not the case when it comes to cars running with an auto stop-start system because your engine isn’t restarting cold. The engine was still hot seconds ago.


Another point to be aware of is the cars with auto stop-start systems in place are essentially built to withstand additional stop-start life cycles than that of those without.


Is it a want or need? To each their own. But with more and more manufacturers looking to adopt this technology, even with their low-tier range, there is nothing with learning a thing or two about them.
