Although those S4 numbers are probably measured at the engine. Either its 4.4 second time is generous (including rollout and under only very specific conditions) or these dyno readings are a little high.

No because every dyno is different, they are simply a comparison tool. In this case you're comparing two different cars. Usually you're comparing you care before and after modifications. Take these two cars to a different dyno and you will see different numbers but similar curves.So, does this mean the Performance is underrated at 450 HP/471 Torque? And there's zero drivetrain losses like an ICE?
They tried that in the Roadster and unfortunately the "world of difference" was the transmission blowing apart. It's likely possible to add a a transmission. However the question though is more about feasibly in price, durability, and overall performance due to overall weight increase and mechanical losses in the drivetrain.I'm surprised to see they lost over half their torque as the climbed through the revs. even a 2 speed transmission would would make the world of difference in these cars.
Curious that the P has the slower onset on the curve by about 400RPM (2500 vs 2100). An artifact of the testing equipment, that it's not really measuring accurately & consistently down there?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!
P.S. As far as we know what the 2020 Roadster is doing is just making the gearing a lot taller and throwing a lot more motor behind it to keep the acceleration at the bottom end a bit above the P100D. It's got so much motor that lower gearing wouldn't be usable due to tire limits.
I think you’re confused on terminology here? Rear-End Gearing SimplifiedThis isn't too likely based on the top speed. Three more powerful motors and more power from the battery pack means they could use shorter gearing to optimize for top speed and still accelerate faster than a P100DL.

No worries, it happens.I read your post completely wrong. I have no idea how I did this, or WTF came over me. I apologise, and I accept my thumbs downs.

Wow! Thank you for doing this? What kind of P3D was it, a + or a -?
Do we know what the differences are between the P3D- and the P3D+? If so, please point me there. I haven't found them.
Is this part of the explanation why the M3P doesn't seem to quite kick/jerk very hard off the line vs at 20-40mph or a model S?Curious that the P has the slower onset on the curve by about 400RPM (2500 vs 2100).

Same here, I have noticed the Model 3 P takes a fraction of a second when you floor it...gets rolling then rolls all the power in. Maybe this is to help save a little wear on all the drive components? Maybe a Ludicrous mode in the future that will throw all the power out from the start.Is this part of the explanation why the M3P doesn't seem to quite kick/jerk very hard off the line vs at 20-40mph or a model S?
Price ? I think not. I pay 0.5 US cents a mile for fuel.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).

All I meant was the suggested retail price listed in the press release I linked to. I wasn't trying to start a debate on total cost of ownership. I was just pleased to see that the Model 3 LR AWD compares favorably to the sportier Audi S4 when I've always heard that it was intended to compete with the A4.
Heard from whom?
The A4 is much nearer the RWD Model 3LR performance-wise than it is the AWD Model 3.

Yes this is what my pant seat dyno says, too. Good to see some more objective measurement to back that up.The dropoff at the low end is just an artifact of the dyno. Not sure why it behaves that way but it does.
I posted a VBOX run in another thread. The low end of the dyno curves are just not accurate for whatever reason (actual torque is obviously pretty constant all the way down to near 0mph based on the instrumented run - acceleration is constant pretty much from 0mph).
Does anyone else feel like the first 0-10mph are limited in the M3P?
