Elon has tweeted that his go to car will be a Plaid CT. The assumption by many, but not confirmed, is that tri-motor CT is the Plaid model.
Anything that big getting to 60 in less than 3 seconds is by definition Ludicrous. But yeah, I’m one of the many folks who believe that the trimotor Cybertruck is basically the Plaid power train.
Plaid powertrain no doubt, but unlikely to have a plaid mode acceleration similar to the ludicrous mode in S/X. It will probably have sport, standard, chill, and tow modes.
I actually think it will have either Ludicrous or Plaid as an option - they wouldn’t want the sub 3 second 0-60 to be the default operating mode for fear of what will happen to unprepared drivers.
