Even if the hydraulic drive is less efficient than a manual or automatic transmission, it doesn't matter.

You can't consider a specific driveline part when the dynamics of the drive system are changed. With a hydraulic drive system, the fueled engine runs at it's most efficient RPM/load ALL THE TIME. Your car doesn't do that.

Even if the hydraulic setup were only 70% efficient, it would probably (most likely) still beat anything on the market currently, provided it would actually be built and work.
