FWIW Subaru Australia
lists the following tow capacities for the "Impreza 2.0i-S Hatch" with CVT. The 2.0i with manual is the same.
With trailer brakes: 1200kg [2,640 lbs]
Without trailer brakes: 650kg [1,430 lbs]
Maximum tongue weight: 120kg [264 lbs]
With trailer brakes: 1,500lbs
Without trailer brakes: 750 lbs
Maximum tongue weight: 200 lbs
Subaru is one of the few manufacturers in the US who list tow capacities for small cars, at all. Subaru Canada doesn't seem to list them at all.
