Id like to try to contribute.
Torque is "work done". it is the Twisting force. while Horse power is (in simple terms) Torque x RPM.
Notice how the VW golf 6 TSi has 260Nm of torque but only 160HP, While the Honda civic Type R (FD2R) has "only" 215Nm of torque but 225hp?
the higher the torque, means your car will pull harder, feel more G on your seats, and (if torque is high enough) create wheelspin.
but depending on the engine setup, peak torque will arrive at different RPMs.
As rule of thumb, what car makers want is peak torque to arrive LOWEST possible, and maintain the peak torque AS LONG as possible.
But of course we live in a world of compromises, so what car makers do is either sacrifice top end power and tune the torque to arrive as soon as possible for easy daily driving and good over taking (i.e VW Golf TSi), or sacrifice low end for high end racing needs ( Honda Civic Type R FD2R)
Theoratically, Top speed is controlled by your gear ratio. problem is can your car fight the wind resistance at 180km/h, 220km/h 250km/h.....that is where Horsepower comes in.... the higher the HP, means the car has more Torque at higher RPMs.
Assuming car A has 160Nm or torque @ 4000RPM
Assuming car B has 160Nm of torque @ 6500RPM
automatically Car B will have higher HP readings... but it also means Car b will need a lot of RPMs to FEEL the same pull as Car A.
on the other hand, Car A will feel much easier to drive in city, stop-go situations. which is why Toyota cars feel much easier tot drive than Honda cars because toyota tune their cars for lower torque band.
Sorry for the long winded post. just my 2c contribution.
