Hydraulic Hybrids were at 78% 4 years ago, according to sources at Next Energy when I went there in 2006.

I hold electric regen round-trip efficiency to be about 70%, excluding losses in the tires. Page 33 of
this document shows motor*inverter efficiency (which needs to be squared for round-trip) was measured at >0.9 across the most usable part of its range of operating speeds. Losses in the battery are very small.
