Look at the demonstration vehicle at the bottom of the linked article. A passenger car with an EPA rating of 80 MPG combined.
In that 198 page document they admitted that the bent axis pump used in the vehicle had serious problems with high speed efficiency. The quote I remember was them asking for a "clean sheet of paper design" for a drive pump-motor that would not suffer the high speed efficiency losses of the bent axis pump they used which ran at prop shaft speed through a regular differential.
That knowledge was the basis of my design which is located in the wheels of the vehicle and not only is much more efficient at high speeds, BUT IT NEVER HAS TO RUN AT HIGH SPEEDS IN THE FIRST PLACE, unless your are talking about 200+ MPH.

Those demo vehicles show how criminal our current offerings for good fuel economy cars really are. With a full series HHV Diesel Sedan we should have several 100+mpg options available to choose from...
