I can figure out what ECO does, but coming from an ICE vehicle, changing to Sport (or Dynamic) mode will change shift points. Since there is no transmission, what is the difference please?

Thanks

If you have the fanciest suspension, dynamic mode also firms up the shocks, reducing roll and increasing the feel of some impacts.

Oh, and it changes some display colors. COOOL!

The colors, yes!

I love the visual cues in the dash display. It's incredibly well-designed. The tickmark to show the max regen, the white arc when you're in dynamic mode, the adaptive cruise control markers on the speedometer. Really nice.

I sat in my buddy's new MY today. It's the right car for him, it's impressive tech, looks pretty good but uh the interior is a motel 6. Ugh. jsimon, how do you cope (haha)

You say hurtful things. I'd never say anything like that. <sob>

Yes, Tesla interiors are low rent. I see the MY as a Subaru Forester replacement. It's a fast EV, and I can attach a hitch. Also, with the supercharger network, we could make it to socal and back without too many headaches, especially if we leave early in the morning to miss the crowd, which we usually do. Granted, the way I drive, it might be touch and go.

Meanwhile, soon, the daughter will take the actual Forester, and in not too distant a future, the son will need his own chariot as well.

Dynamic mode will adjust the pedal rate (sorry I don’t know the English word for it)

in most ICE cars it doesn’t really change anything at the engine. It would just change the ratio on how hard you have to push the pedal to get x% power. With the difference of the feeling from your foot,the car feels faster and more spontaneous on the throttle.

overall you can have the same sprint in eco mode, you’ll just have to put the pedal to the floor.
Sorry for the bad English, I hope you get what I mean :)

Dynamic mode has 50/50 torque split between front and rear motor; comfort mode has 0/100 usually.
Eco to comfort to dynamic has increased throttle response. Very noticeable.
I only drive in dynamic .. never use any other mode ... I know immediately when I forgot to switch to dynamic upon startup.
I read somewhere, probably on this forum, that you had the rear motor always putting out 100% of it's capabilities and the front motor only put out 70% normal mode with 100% in dynamic mode. That appears to agree with my tire wear, as the front and rear tires are wearing evenly, the same as my awd STI used to do. Do you have a source for the 0% front drive?

I will give this a go for..... Have been happy w/just comfort, but you only live once right ?

Some people have weak ankles.
I use the same settings as Tri, but then I've been told I have the ankles of a Greek god (not sure how the little wings and gimpy heels help).

I wonder about the power split in the different modes and how it may impact the wiring harness issue. Are folks who are seeing the problem using dynamic mode as opposed to comfort? If comfort is using 100% rear in most situations, then that would seem to put less stress on the front wiring harness in terms of motor torquing/twisting, but perhaps the stiffer suspension in dynamic reduces movement, or maybe the 50/50 of dynamic avoids the sudden application of power to the front motor that you'd see in comfort during hard acceleration ... or none of the above.

I thought it was impossible to have 100% rear power due to the way the front motor is designed?

The ratio between front and rear is not static, it depend on the speed, and torque. Here is a couple of graphs that shows the different dynamic ratio at different speed in different mode. The blue line represent the power delivered to the rear motor, the read line represents the power delivered to the front motor.
In Eco mode, the 70:30 ratio is almost there. In comfort mode, at low speed (< 60km/h), low torque, you can see the 0:100 ratio, otherwise it is 50:50. In dynamic mode, it is 50:50

Thanks,
The charts are great!
My observations of the charts:
Any time you're at full throttle in any mode, both motors have the same torque. (yellow line rising quickly)
The Front motor appears to be the only motor controlled by the mode switch.
90-100km=56-62mph is my most used cruising speed and the motor's torques(& tire wear) are equal in Comfort and Dynamic.(Actual Verification!). I have never put my car in Eco. I don't know how to!

Great charts.

Having a full slew of European genes, I believe roundabouts (traffic circles) are fun inventions and should be taken at speed. A couple times whilst in comfort mode on wet roads I have felt the rear end of the I-Pace start to slide. The car quickly recovered and pulled thru the turn, so no real concern. That said, I now routinely switch to dynamic in wet conditions and haven't felt the same breakway.

Would be interesting to see these graphs whilst cornering on slick roads.(Not encouraging anyone to be cavalier in dangerous conditions!)

I guess I will be in minority here, across many who are driving in Dynamic on permanent basis, but... Coming from Tesla MS, I really like ECO exactly due to more delicate/precise throttle response. And flooring it, will do full power anyway.
High-sitting bouncy suspension (apparently I've got just "fancy" version) is bothering much more than any acceleration-related topics

Other differences that I noted are the louder Active Sound Design in Dynamic (if not switched off completely) and a more aggressive regen activation. As with throttle, the maximum regen won't be different across modes; but I feel that in Dynamic, regen builds up noticeably faster than in Comfort & Eco.

Lower tire pressure to improve the ride. With proper inflation, the ride is generally sporty but not rough.
