I'm not sure where your getting that idea from, but you should probably try driving a modern diesel car. Mine is making more torque at 1200rpm than most 2.0litre petrol cars do anywhere in the rev range. I'm not sure what you class as pulling power low down the rev range, but IMO thats what the torque is all about. Not that it really matters, coz proper drivers dont want to boot it at 1200rpm, and would downshift anyway.
