Any chance the subject title of this thread could be edited? 'Breaking' and 'braking' are very different things and it could be misleading to people searching in future.

Yes please - I thought the topic was that the ACC was broken!

Haha, right. Pardon my English, break or brake sounds same to me ;) Can't change the subject myself, not sure if an admin could do that?

Anyway, if you could test on your car braking this time while acc activated it would be appreciated.

Bringing back this topic, now that more of you have the car, maybe can get more tests done.

Turn on acc and lock the speed. Drive as normally you do and then brake at the traffic light or just whenever needed (like in city environment). Check the main displays: is the car regenerating while braking?

Iv60 in my case it does not regenerate most of the time. Sometimes it does. Regenerates properly every time I brake if acc is not used (semi active, but speed not locked).

Anyone else has this bug?

Regen breaking works fine all of the time - I watch ithe display at junctions, roundabouts etc. especicially noticable with travel assist on.

Thanks Perchede. Just to confirm that is with "manual" braking? So then the acc disengages? When it brakes itself it works fine for me.

My observation is that there is less apparent regen when I’m manually braking, compared to when ACC brakes for me at roundabouts etc.

Remember that when the car is controlling the 'throttle' it will only add enough power to maintain the speed it needs do, so will tend not to overaccelerate and need to slow down as often as a person would. I've noticed when approaching a roundabout on ACC it regenerates plenty, though it does start decelerating earlier than I would - which no doubt is better use of energy. Generally I think it'll always prefer to use regen to slow down (as it does in auto-regen D mode), because it's aiming to maximise efficiency.

The only time I've known ACC apply the friction brakes is when I came off a motorway on a curved slip road and it accelerated until it saw the cars waiting at the roundabout and then friction braked rather than regen braked so we'd stop in time. Obviously I could have taken over at any time and stopped it accelerating but it started braking fractionally before I was about to start doing it anyway.
