Thursday's re-test of the T-100/Viking reinforces my confidence in the predictions for the Prius tadpole trailer.
With gap-fillers,the T-100/Viking rig is predicted to fall from today's Cd 0.198,to Cd 0.159.
If I repair the existing damage to Viking from December 2009,and complete the fairings which were planned but never completed,the drag should fall even lower,approaching the Cd 0.143 mark predicted for the Prius,who's weight will be only a fraction of that of Viking.
