In the U.S. only the 1st Edition and the AWD models are available with the factory tow hitch. I wonder if that’s because the 1st Edition has larger front brakes than the RWD Pro and Pro S models? There’s a leaked dealer spec sheet floating around somewhere that lists technical things like the brake size. I seem to recall the AWD models have 14.1” front rotors and the RWD front rotors are smaller than that.
