Horsepower equals torque times rpm. Let's you have two engines, each of which produce the same rated horsepower, but one produces that horsepower at 2000 rpm and the other at 4000 rpm. The slower engine must necessarily be producing twice as much torque to produce the same horsepower. So, in this context, the slower engine is the "high torque" engine. Both engines will do exactly the same amount of work, but the slower engine produces much more torque.
