Don,
That's agrees with what I was saying, it isn't always the engine size
that determines towing capacity. The PT Cruiser has a much more
powerful engine than the Forrester X (230 vs 173 HP), but the PT only
has a 1,000 lb towing capacity.

Please don't misunderstand what I was saying before. I don't think the
PT Cruiser is good for towing big boats. I was just saying that it
wasn't the 4 cyl engine that was the problem. The lower powered
Forrester with 4 cyl has a higher towing rating.

Or maybe the manufacturers arbitrarily select the towing rating, and
the Forrester will burn out fast towing 2500 lbs. ???
