I don’t know where you get
I don’t know where you get the impression the single motor Cybertruck will be out first as that goes against absolutely every bit of evidence. Tesla always, always releases the more expensive models first and then only after they have made plenty of high margin sales do they finally, reluctantly release the cheap low margin models as economies of scale kick in.
In the case of the elusive $35k Model 3, it’s been more of a tease than a vehicle that has ever properly been available.
No, it will definitely be the tri-motor and dual motor first as Elon has said all along.
In terms of manufacture, you forget that Tesla has been manufacturing EVs far longer than Ford and the flat stainless steel panels of the Cybertruck are far cheaper and easier to produce than the expensive presses required to produce the curved panels of the Ford.
