I comes down to Politics. Speed limits are high in the U.S. and we don't have a national towing speed limit, also regulations my differ from one country to the next.
That said, Force = Mass x Acceleration, so if you slow down the towing vehicle you can safely tow a greater weight. <-- Most likely reason a single-spec global vehicle has different tow ratings on three different continents.
