A more accurate way of comparing one car to another is to measure the ratio
of effective drive-wheel torque-to-weight rather than lbs/hp or lbs/ft-lbs.

This method takes into account the gearing of the car and explains why some
cars appear to be a lot quicker (or slower) than their lbs/hp would tend to
suggest.
