Is this a user interface or via tune?

It seems like you believe that Start/Stop is somehow more advanced than e-Assist. The opposite is true. Start/stop is simply that. It shuts the engine off when you stop, restarts it when you’re ready to move. If there is not enough charge in the battery to maintain auxiliary usage, it simply doesn’t turn off when you stop. With e-Assist, the A/C has an electrically driven compressor that can continue to run on auxiliary power when the engine is not turning. Start/stop doesn’t have that.

My 2016 Cruze has Start/stop. It does not turn off at every stop. Certain conditions are built into the system logic. For example...it doesn’t turn the engine off if outside temperature is below 42 degrees. So during the winter it never shuts the engine off. Then, when the weather does permit, it will only allow the engine to be off for about one minute....maybe a little more, depending on state of charge of the battery. If there are a lot of frequent stops, there will be times where it doesn’t turn off at a stop simply because the amount of charge is not sufficient. e-Assist is a lot more robust, and can start the “turn off” process as the car is slowing down, not just when it comes to a complete stop.
