My beloved 2018 Model 3 was broad-sided the other day, so all of a sudden I'm in the market for a new one. I noticed that the acceleration and battery range for the 2021 Long-Range AWD Model 3 are 4.2 secs and 353 mis, but the 2020 used cars of that exact same model for sale on the Tesla website show 3.9 secs and 322 miles. Does anyone know why the differences from one year to the next? Thanks.

Differences in Acceleration between 2020 & 2021

It does not. The motor is the same. The Performance motor is different, hence the lower range. There is no difference in power between a 2020 and a 2021.
I had assumed the difference was all in the tires and aero wheel covers. What is known about the difference between the 980 and 990 motors?

The main differentiator in range between the M3LR and M3P are the larger tires on the P.

False. Yes, tires are the main factor regarding Tesla's range estimates but the motors are absolutely different on the 2021.

This has been discussed at length on this forum. The LR and P motors have been different since 2019. 980 vs 990.
980 vs 990 motor settled
I know there's been speculation on here that this was the case. Nothing definitive, because internet. But this "tuning" company figured it out: Ghost Upgrade - Why is it restricted to the 1120980 rear motor? The power electronics are superior in the 1120980 motor. Model 3 Performance models...

Ignore everything above about tires. That’s not answering the question.
To answer your question. The 2021 model 3 has some efficiency improvements such as the heat pump and potentially larger battery (82kw) that account for increased range of 353 miles.
2020 model 3 LR gets 322 miles because it does not have the improvements of the 2021 models.
To my knowledge the only difference is higher current inverter in the motor and that doesn't impact the range, only maximum power. Range is impacted only by tires. Am I wrong?This has been discussed at length on this forum. The LR and P motors have been different since 2019. 980 vs 990.

It's not tire size, it's the compound that creates a large difference in rolling resistance. Low hysteresis is needed for low rolling resistance and it is almost exactly the opposite of what is needed for high grip/performance (especially in wet conditions)
