An EVO 8 will be less efficient than a Miata. A Focus ST might be more efficient than a miata.
All comes down to part design, lubricant used, and number of parts.

I understand and agree completely, I'm just thinking 'losses' for a Focus ST 6 speed transmission or a specific model torsen diff aren't fixed, but rather vary under different loads and rpms. Same for every other component in the driveline. But maybe saying a Focus ST 6 speed has total 15% power loss across the rpm band under WOT is a close enough estimate so that it doesn't matter? I think in the end when looking at dynos, it's all about relativity anyway (non-einsteinian) - the graphs mean the most when comparing the same car before/after mods/tuning.
