The number I kept hearing at the car show was 20%.  Rule of thumb was a 
20% loss from the flywheel to the road with a manual transmission.  
Don't know about an automatic.  I will ask a few of my powertrain 
buddy's at Ford this question tomorrow.  20% seems consistent with 
numbers I got for Sophy.
