In europe you are not allowed to tow anything on Prius is it allowed in the states?
Hauling extra batteries is one of the premises for the invention.
An extra 2,000-lbs ( 909 kg ) only costs 2.94 horsepower in additional road load from rolling resistance at 50 mph ( 80.5 km/h ).
At 55 mph ( 88.5 km/h ) Gary's trailer can add 11.3 mpg from drag reduction,with 3.77 mpg loss due to R-R ( radials ),4.1 mpg loss ( bias-ply ),for a net improvement,from 53 mpg,to 60.2-60.5 mpg at steady speed.
---------------------------------------------------------------------------- A Nissan Leaf,or plug-in EV,on a road trip,would extend the range of the initial battery pack,and carry the second pack with no penalty,only gain.
