Thanks to @EVino for posting the video of Tesla’s VP of Regulatory Affairs, Jim Chen:
@TeslaTap.com found a nugget at 00:09:40.
This vehicle have class 3 Towing Capability. That means over 5,000 pounds--actually close to 10,000 pounds towing capability.
A chart from:
Class III hitches are weight carrying (WC) and also are weight distributing (WD) depending on the vehicle and hitch specifications.
Not all Class III hitches are rated to be both. See the specific hitch for that information.
Class III hitches used as weight carrying are rated up to 6000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 600 lbs.
Class III hitches used for weight distributing are rated up to 10,000 lbs. gross trailer weight (GTW) with a maximum trailer tongue weight (TW) of 1000 lbs.
A Class III hitch usually has a 2" square receiver opening.
A higher class drawbar does not increase the towing capacity of the hitch. To use this class of hitch for weight distribution requires a weight distribution system.
Class III hitches attach to the vehicle frame only.
So what can Model X actually tow?
