I had the old version, XM1. It did last long. Had around 30,000 kms on the tire and the thread was still very thick. Almost looked new. Seem to save a little fuel but not enough to make me buy it again. Found it a bit slippery and noisy.
AFAIK, the Energy Saving tires usually have poorer traction as they are designed to have less rolling resistance. CMIIW.
