Would be great to have another data point.
@MountainPass - were you guys the ones that did the RWD M3?

Oh ok your about 3 hours from me. I do have to get some service done in Oakville at some point so if no one has done it by then I'll reach out to you to see if we can make it work. If you want PM me your contact information and I'll let you know when I have the service scheduled.
Yes indeed, it was the first thing we did after we picked it up, we also did SOC dyno testing:

I have a service date scheduled for December 21st. at the Tesla service center in Toronto-Mississauga 420 Ambassador Dr. Apointment is for 10:30am and it's to address my doors sticking. I'm hoping it will be a quick visit. I will keep you posted but would like to try to meet up with you guys after that. Let me know if that looks like it would work.

Make sure the battery pack is hot. 100% charge for maximum power, but 70% sounds good for a real world output that most drivers will see on a daily basis. Ideally we'd get both numbers, but that would likely take multiple dyno sessions.

Both of us have a bit of a drive to the dyno so batt will be warm and there is a supercharger within a few miles, we will both charge to 90% for the runs. Since the runs will be back to back, we won't get to test much lower SOC just where the car is at after each run.

Had a couple good runs today on both the cars. Will upload data shortly, thanks to all that helped fund about half the cost. And thanks @hoang51 for bringing his car for the comparison.

Ok, drum roll please........... the data is in, we ran a couple of runs of both the M3D and the M3D Performance and the comparison graphs are attached.
Also ran a run of both cars in Chill mode with very minimal deviation between the two. Both cars were close to 90% SOC and dropped to close to 80% by end of runs. Power output varied by less than 1% from 90% down to 80% on the runs, i.e. no loss of performance on the SOC drop at high level.

Thanks @hoang51 for the long drive down for the P3D!

Performance in Blue, Dual motor in Red. lower graph of green and yellow are both cars in chill mode.
It's interesting that it looks like almost both max torque and max hp are both about 100 from AWD non p to AWD P. Also that the torque graphs are almost identical in shape. Another thing is that the non p graph looks like it reaches a certain power in both torque and hp and is held at that level. graphs are almost flat. Where as the AWD p is more bell shaped. could this be software limits? I guess could be a safety limit for the non p as the motors where not tested like the P motors where.
Also if you look at the chill mode, the graphs look identical in shape to the non p AWD one.
Thanks for doing this for us, I will post my results from my visit to Mountain Pass. If they are willing I will try to do runs at the same state of charge that they did for the RWD. Of course this is entirely up to them if they will allow me to do that many runs.

You can see in the video above when MPP dyno'd the LR RWD they saw negligible difference between 90% SOC and 95%. They didn't even bother with 100%, the big step was from 75% to 60% (at list their initial test, I don't know if that's ever been corroborated). Sure the AWD could be somewhat different because it's got two places to sink the current into so more potential to bottleneck on the battery. However bigger picture aiming for use at 100% isn't all that realistic anyway, since it can take quite a while to get that last 5%, it's harder on the battery to go there, and you've got next to no regen so do you really want to drive like that anyway?
Big thanks to @ScottFrancis for getting the dyno meet going. It was satisfying to get dynos of both Model 3 Dual Motors and Performance for comparison. Just letting folks know that I collected some more videos of the runs we did. I'll try to get them processed asap.

Thank you for doing this! Very interesting to see how closely the standard AWD matches up to the 2018 Audi S4 in terms of power, speed, and even price (354 HP and 369 lb-ft of torque).
