R1S Dual Motor; Any harm in choosing Reduced Stability for kinda Sport Mode?

[Brian-MS90D]

Loving my R1S, Dual Motor, Max, 21". Road tripping beast! I couldn't find the answer to this question when searching the forum. When in All Purpose and Stability set to ON, then the vehicle drives like most are familiar with where the rear motor will disengage above ~ 22mph (assuming no aggressive acceleration) leaving the front motor to do all the work. This works well 95% of the time, but sometimes when driving hard the inherent drawbacks (physics) of a huge, heavy SUV are realized (aspects that the Quad Motor and/or Performance option likely help address).

I've noticed that if I set Stability to Reduced, then both motors are always engaged (for acceleration and regen) and the rear motor does most of the work. It feels awesome driving and like what I would imagine Performance mode feels like (the rear motor also sounds cool).

You can see that the rear motor is doing more of the work than the front motor. With Stability set to On, the opposite is true; the rear motor does less than the front and the rear only comes on to "assist" getting the vehicle going from a stop.

Is there any negative to driving with Stability set to Reduced as a "poor man's" version of Performance?

I know one negative is that Traction Control is disabled. Is Traction Control also disabled when in Performance/Sport mode in the Performance model?

I searched for about 30 minutes, but haven't found anything written about this except for using Reduced Stability or Off Stability for offroad reasons. Is anyone else using Stability on Reduced in their non-Performance Dual Motor to get a better performance feel when driving harder and for the rear motor doing more of the work?

No clue. I also have a DM and just the other day was playing around with Reduced stability but did not observe your notes about the rear wheels being used more. I will play around with it more now. =D

Just be aware that when you get in 500+ hp territory, turning off traction control and/or stability can be fun but also risky. Google "supercar traction control off accident" for tons of sad stories.

A friend of mine was given the opportunity to drive his buddie's Mercedes SLS AMG. My friend is not really a "car guy" so he didn't know how much he didn't know. He turned off traction control and floored it, and spun the rear into a low curb. Fortunately the only thing damaged was the wheel and tire. He still talks about his $3000 5 second joy ride, lol.

I'd be very interested to hear from owners of the performance versions to see how well they compare.

I suspect there are other suspension tuning differences. But, it's possible that it's still very similar, just with less hp.

I can't confirm that the dual is the same but in the quad reduced stability makes a very noticeable difference in how the throttle feels. It ramps up a lot quicker and when you floor it from a stop you can hear it chirp from the wheels slipping for a few milliseconds.

It is a lot of fun, but the tires are going to wear out significantly faster if you do it a lot. Reduced lets it slip enough that I leave the garage door open for a while after a "fun" drive to let the burnt rubber smell dissapate.

You also will want to put the suspension as low as it will let you go if you are trying to emulate sports mode. I think the main reason that the quad has reduced power in all purpose mode vs sport is because the higher suspension settings can't handle full power.

I can feel it struggling to keep the wheels planted at full throttle on anything higher than lowest. It also feels like something might break if you are turning while accelerating heavy while higher than lowest. It feels like vehicle is reducing the power to protect itself.

I'm not sure if "lowest" is a choice on the non-performance, but the closer you can get to it the better.

I've messed with it a bit but it resets on the next drive. Definitely a bit less front drive bias but Sport mode has tons more power and is always AWD. Might be a good compromise for a better road feel but still have automatic conserve.

I too notice this, but never really looked into it.

To me, all four wheels going should be "safer" right?

I'm not sure "safer" would be accurate because if you look in your binnacle, Traction Control is disabled when Stability is set to Reduced or Off. I think the best analogy might be that turning this on is similar to turning on Track mode in a Tesla. Or any mode in a car that is disabling Traction Control features to let the user drive it more like a simple car from the 1990's and prior (of course that puts more responsibility on the driver to keep the car on the road).

And, with All-Purpose mode and Stability set to Default, the rear motor will engage with hard acceleration at any speed.

I think the "fingerprinty" screen is doing more harm than running in reduced stability with both motors. Nice hack btw, that's pretty cool.

Hmm if I do reduced stability, my tire wear will be evenly distributed like my model Y. Tires wore out so evenly I technically didn't need rotation for the entire life of the tire.

In theory, driving more in Stability Reduced (where the rear motor will always being engaged and do more work than the front motor) should result in more even tire wear.

I'm also not always a fan of regular tire rotations, especially for big heavy vehicles. Sometimes the negatives with frequent tire rotations (expense, time, potential for uneven wobbly ride) are simply not worth it and it's best (IMO) to just run the tires to the ground as they are and then buy 4 new. Not always, but sometimes.

Drove around a bit in my PDM in reduced stability and it’s quite fun. Not like sport mode but nice to see power and regen pulling/pushing from all tires the whole time. Regen seems to stop in the rear under 10mph when stopping at a light. Otherwise, it’s great!

Nice find!! I'm going to have to check this out for myself, since I haven't had much time to try out the different drive modes yet.

Setting my R1S Dual motor to Reduced Stability makes all the difference. My biggest disappointment when finally getting to drive my R1S (after delivery) was the poor accelerator pedal response. Coming from a Tesla Model S where the pedal travel and acceleration were very linear the R1S seemed very sluggish. Part of this was needing to push the pedal farther but there seems to always be this brief lag when accelerating. It feels like it is down shifting like a ICE. Watching the motors on the screen you can clearly see that it is the delay in the rear motors kicking in. Switching to Reduced Stability and this all goes away. It is so much more fun to drive. The down side is that it always reverts back to On when you get out of the truck and I forget to switch it back. It would be really nice to have a poor man's Sport mode. I do not need launch mode or more horsepower. I just want to have the linear pedal feel that I used to have.

I don't mind it much. In a way it helps promote a smoother acceleration and ride possibly. But like you said, it forces you to push the pedal harder to get some more acceleration. This might be why my partner struggles with the R1S. She has shorter legs and feet and generally for her it's 'too hard to press the pedal'. If they made it more linear like possibly what the Tesla experience is (I've never driven one) or how my Ioniq 5 is in 'Standard' drive mode, than it might make it easier for her to press the pedal and maybe she'd enjoy driving the R1S a bit more.

I do like the way it drives in Reduced Stability too. In another thread, I don't remember who, pointed out that in that mode, the rear wheels tend to be engaged more consistently through higher speeds for both accel and regen too. I wish it wouldn't switch back automatically to Stability 'On' as well, but I'm sure they do that for safety purposes.
