Pretty sure in the U.S. 1,500 lbs. is the limit for an un-braked trailer.

 

Assuming that the factory releases a hitch solution for the RWD cars, I would assume it is the same as the First Edition. 2200 lbs with brakes. I don't know what the tongue weight is rated for, usually 150-250 lbs for a Class I

 

Physically the hitch for the RWD version and the AWD version is the same, it is a 1.25" class II hitch. The AWD has a higher tow rating due to having larger front brakes.

 

In the US, FE has a hitch installed and wiring, but you have to put an adapter to the wiring for the socket, $12 on Amazon (https://www.amazon.com/gp/product/B000B6NQHW/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1). The 1 1/2" receiver can use a 2 1/2" drop hitch, with a 1 7/8" ball. Max tongue weight 270 lbs.

 

Does the AWD have physically larger brakes or greater braking capacity due to the front motor's regenerative braking?

 

There was a discussion of this a while back. In the service manuals there are 2 models of brakes listed 1LB/1LF and 1LC/1LN. We have confirmed that the FE's with the hitch have the 1LC version which are bigger and have 2 piston calipers. If someone who has a Pro or Pro S and could check their build sticker to see which code is there is we could narrow the question down a little. I am betting that the AWDs have the 1LC brakes like the FEs.
