Introduction
Economy camshafts are the opposite of "hot" cams favoured by racers. But rather than aiming to increase high RPM performance, economy cams are cut to enhance efficiency at lower engine speeds where ecodrivers tend to drive.

"Cool" cams may have lower lift, duration and more advanced timing than regular cams, resulting in more low end torque at the expense of high end power.

The Geo Metro XFi had a factory economy cam, and owners of garden variety Metros regularly swap it in place of the standard one.
