This graphic attempts to illustrate the concept of w:power band and the difference between a torquey engine and a peaky one.

The "torquey" engine, illustrated by the blue lines, makes greater levels of peak torque. The "peaky" engine, illustrated by the red lines, produces less peak torque, and significantly less torque at the lowest RPMs, but produces adequate torque at much higher RPMs; as a result, it produces more peak power.

The "torquey" engine, by virtue of its higher torque at low RPMs, may be easier to drive in day-to-day use. The "peaky" engine, with its higher power, may be faster when driven aggressively, keeping RPMs high.

This graphic is essentially made from my understanding of the topic and needs to be revised as more hard information is incorporated.

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Powerband.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
