The hydraulic system in this case lists losses of %95 and %96 and %91 for the pump, hydraulic transformer and the in-wheel motors(~%83 efficient transmission from the engine) plus something for the accumulators. The hiway milage would be much better with a direct coupling (and the right engine).
Hydraulic is an excellent regen system.
an 83% efficient transmission? not so much, I would rather take my chances with a stick shift there, and hold in the hydro-boost button accordingly.
