Chip,
Thanks for taking time to put HP vs. torque into tangible context for us laymen!

Different engines are designed for different purposes in mind. Locomotive or commercial freight ship motors are optimized for low-end torque because maximum "twist" is required to get that much mass moving from a standstill; likewise, as was demonstrated in the CBR vs Chopper video, massive amounts of low-end torque can help you get off the line faster, however, if that race allowed for the CBR to reach near the high-end of 2nd gear (or even 1st), it would be lights-out. The CBR is optimized for maximum HP, which takes place near redline, whereas the V-twin chopper (undersquare, long-stroke) is optimized for low-end torque. Massive amounts of low-end torque may be perceived as "responsiveness", particularly off the line; whereas engines optimized for maximum power typically experience peak torque and peak power near the upper end of the RPM range.
