Brake lights during recuperation?

[mjw930]

I really don’t understand why this concept is so difficult for folks to comprehend, Porsche does not have one pedal driving. Accelerator pedal lift deceleration occurs at a rate mimicking an ICE vehicle engine braking, probably in a manual or PDK that’s directly coupled, not a torque converter auto, which isn’t as effective when it’s not in lockup. Lifting your foot off the acceleration pedal will never trigger the brake lights on a current Porsche Taycan.

ACC IS NOT pedal lift regen, it’s ACTIVE meaning it will apply braking force as needed based on the situation. Whether it slows the car with recoup or brake application is irrelevant, it will active the brake lights when deceleration is higher than the required rate. Just like ACC does on every ICE vehicle it’s deployed on.

I truly hope you're wrong. During a "spirited" drive with autoregen on, I managed to get the green recup indicator to hit max (270kW of recup) more than once with slower traffic in front of me. If that didn't trigger the brake lights, I'm lucky not being rear ended if someone decided to tag along.

Perhaps AutoRegen works similar to ACC. It only engages when traffic in front of you slow down, right.

I guess what was stated above your post was the normal regen, because I would also be nervous if the brake lights would not light up in such a massive regen.

Yes. Normal regen fills the bar for like 10% at most. Don't expect lights to go on like that. Feels like normal engine braking on ICE cars. Auto regen though is way way more powerful. It doesn't stop the car but will slow down until regen disengages all together (<15km/h maybe? Don't know the exact speed)
