I mean, you are free to believe what you want of course - but we do not currently have a single example of a recent (since early 2019) AWD with a 980 motor in it. And we have many examples of recent AWDs with 990 motors. And we have never seen a Performance with a 990 motor. Including all recent Stealths that have been checked... That is all I am saying.
Stealth:
Recent Example
Another Example
AWD:
A recent example
Latest 980 I have seen
Another key piece of evidence: For 2020 models, the EPA results for the Stealth (18" Performance) and the AWD are not the same. The 18" Performance is more efficient. They are very, very likely to be different vehicles. Unlike in 2018.
Ok, you convinced me. I stand corrected, thanks.
