Regen levels across all driving modes

[Adnillien]

I have seen a lot of people write about how regen is different in the different driving modes Smooth, Swift and Sprint. I have never been able to feel or sense an difference. Since many smart forum members say there is a difference, I decided to test it out. I found a level road and measured the time it took the car to decelerate from 50 MHP to a stop in each mode with both high and standard regeneration. I did this 3 times on each setting and then averaged the results.

Setting	Seconds
Smooth Standard Regen	11.0
Swift Standard Regen	18.0
Sprint Standard Regen	17.7
Smooth High Regen	9.3
Swift High Regen	9.3
Sprint High Regen	9.3

Since I always drive with high regen, it is clear why I did not sense any difference across driving modes. High regen is the same across all drive modes. However, standard regen shows there is a big difference between Smooth mode and Swift/Sprint modes. I believe that the small difference between Swift and Sprint with standard regen is measurement error.

Conclusion is that if you want the least regen, use standard regen and Swift or Sprint Mode. A moderate amount of regen is available using standard regen in Smooth mode. For maximum regen, just set high regen and use any driving mode.

A lot of runs here for one person.
Thanks for taking the time to do this.
Very helpful and informative.

It was actually kind of fun. Although I did not time it, I did not spend much time getting up to 50MPH. I spent more time trying to stabilize the speed at 50 than it took to get to 50. Almost 11 months in and still looking for excuses to drive.

Very helpful information! Thank you

Interesting info.

It would be nice if we could have sliders to personally tune the regen and suspension.

The AMG EQS has regen paddles on the steering wheel. AT first, I thought that they were unnecessary but have learned to like them. Very easy to tailor regen on the fly.

Upon starting, EQS automatically defaults to normal regen , which is really minimal, so the paddles are really nice to have.

This is great. Thanks for taking the time to do this.

This is good information. I tried the high regen on sprint drive hoping to get a similar experience as smooth standard regen which never happened. Now, I know why.

I am new to Lucid and just discovered this today. My wife and daughter both get nauseous in the car and this discovery will make a huge difference. It’s Swift from now on. Thx

There seems to be a misconception that the ONLY way to use regen is to take your foot all the way off, and "what you get is what you get."

If, on the other hand, you set it to HIGH regen and think of the setting as the 'maximum amount of regen that is made AVAILABLE', then MODULATE the throttle....you get the best of both worlds. You can get anywhere from coasting to max regen, or anything in between simply by intelligently controlling the throttle. More importantly, you can fade it in and out SMOOTHLY, which is key for passenger comfort.

Every passenger I've had in the car (and there have been many) have commented how unbelievably smooth the experience is, including the braking and acceleration.

TLDR: if your pax are getting sick, there's a very good chance that it's driver-induced as a result of taking your foot off the throttle (from cruise) without warning. While that works in ICE vehicles (transitioning to coasting)...the result here is that you're going to go the maximum available regen based on the settings. The solution isn't necessarily to reduce the max regen....it is likely that more nuanced use of the throttle will get you what you need, while STILL giving you access to higher levels of regen breaking when needed.
