Well, the early demo units from back in November did have the other receiver design that was more cantilevered and looked weaker. Maybe it was rated lower and they are now using the same receiver for both 1st edition and AWD vehicles. Regardless, since the overall tow rating for the car would be a function of the receiver rating as well as the motor(s) rating, the 1st edition is likely limited to the 2200 lbs just based off the single motor.
Great photo! Thank you for capturing and sharing.
