I like the concept behind this feature, but I'm worried that it will put more wear and tear on the engine in the long run. Is this a relevant concern?

yes it will definitely reduce the life of the starter BUT the cars equipped with stop/start have a more heavy duty starter. When the concept was first introduced OEMs did a lot of testing on various starters and I say some starters melt within 30k miles but the supplier kept beefing up the starter. I personal hate the stop/start concept and never use it.

They really need to supply people with a way to more easily avoid this feature. My suggestion would be to simply have the vehicle stay in whatever drive mode was last selected. That way, people could leave it in "Dynamic" or "Individual" all the time. Combine this with driver profiles, and it would be ideal.

I think that the greatest problem will be the lead starter battery.

Hybrid cars use the start stop system all the time and don't seem to have problems with it.

When BMW came up with this idea for their efficient dynamics spiel, we had this conversation and the common thing thrown around was "You should be fine with the starter, as it designed to spec and use." However what this spec was was never specified. Fast forward to the present, not many threads about failing starters.

To be honest, you`ll be fine at least till warranty. At about 100k ehh most cars are prone to starter failure anyways.

I wonder how much fuel the feature actually saves over the course of a year.

My petrol Opel Astra 1.4l Turbo uses 0.9 liters per hour idling with the AC off. I expect the 2.0l Volvo to be comparable.
