I've found that towing ratings/ability has nothing to do with size, or brakes, or anything technical really. It's simply a liability issue, especially for US vehicles and their sue happy owners. US vehicle owners towing anything is a major liability and headache for the manufacturers, so it's just easier for them print "towing not recommended". My Yaris, the manual states exactly:
Towing capacity (except for Canada):
Toyota does not recommend towing
a trailer with your vehicle. Your ve-
hicle is not designed for trailer towing.
Towing capacity (for Canada):
318 kg (700 lb.)
Figure that one out... same exact vehicle, but 2 different countries... Toyota doesn't want the headaches of US owners trying to sue them when they inevitably screw something up and blame the manufacturer. The Yaris towing capacity is even higher in the UK owners manual, for the same exact car.
Chevrolet's UK website states the following for the 2014 Trax with a 1.4L Turbo:
Towing capacity braked 1200 kg
Towing capacity unbraked 500 kg
Once again, exact same vehicle, exact same engine, but Chevrolet doesn't want to deal with sue happy Americans blaming them for the owners own mistakes when it comes to towing improperly... Holden states the 2014 Trax LTZ (1.4 Turbo) towing capacity is the same as the UK model, 1200kg braked.
