Auto start stop question

















Also add lame eco start stop eventually destroying your starter. Battery and alternator too from unnecessary draining and charging at every stoplight

I do have my thoughts on ECO start/stop, especially as in the real world it often seems to unnecessarily turn off the engine, just to restart it a second or two later. In order to actually save fuel with ECO start/stop, you need to be stopped for about 7 seconds before there is a net gain. Jason from EE did a nice video on it. Otherwise you actually end up using more fuel due to the constant re-firing of the engine that uses more fuel than just idling it. The jury is out on the long term viability of using ECO start/stop, but hybrid cars for example turn their engines off and on constantly and you may even end up flooring it when it is cold if it hasn't run much yet and suddenly you are asking for power to accelerate. A bit of an issues with hybrid is also the break-in of the combustion engine. It's not broken in by the time the car has reached the break-in mileage, but rather when the engine has been used for enough miles, but that's a bit of a different topic. I think if you drive a lot in traffic and the city, then a PHEV makes a lot more sense, so that for most of this low speed stop and go driving you'll be driving in electric mode and avoid constantly starting and stopping the engine.
