Are we talking range while towing or hauling or range with very light loads?
There will be a big difference, IMO to achieve decent range while towing the range while driving with very light loads might be quite good.
I am not expecting CT to defy the law of physics while towing, so it needs a large enough battery to make it between Supercharger stops, and fast enough charging to be convenient.
The maximum I expect most people towing would want to do is 2 Super charger stops for 20-30 mins on an 8-9 hour trip.
Say 8-9 hours averaging 55 miles per hour, covering say 450-500 miles per day. I think that is what they would like to achieve.
So ideally a CT set up for long distance towing can travel at least 250 miles between charging stops while towing. 200 Miles is less than ideal, but might be acceptable.
The first model available might not have the ideal towing range.
A longer range vehicle suitable for towing might depend on the 4680 ramp, which may in turn be dependent on things like Lithium refining.
Hopefully if the initial vehicle has a shorter range, they provide a rough timeline for the longer range version.
