Area under the curve and peak torque are not the same thing. My point was not that a higher torque number will give you better area under the curve. You have to look at the
entire dynometer graph. You only make peak power at a single rpm level. However, you only drive the car at that engine speed for an infinitesimal period of time. Therefore, what really matters is the collection of all powers at different engine speeds, or more accurately the height times the width. If you decrease the widths to an infinitesimal size and sum over the entire range of usable rpms, you get the integral of the power, which is energy. This is what makes the car go... not peak horsepower or peak torque.
