I'm guessing on the order of Cd0.12.There is no wake,and the kinetic energy of the original turbulent wake behind the Insight has all been converted to higher base pressure,basically eliminating the profile drag altogether,leaving only skin-friction drag and perhaps a bit of induced drag at the windshield header and A-pillars,and a little interference drag behind the sideview mirrors.----------------- HONDA has achieved Cd 0.10 with their Dream-2 solar car,I believe the Taruff twin-boom also had Cd 0.10,and many Bonneville cars (like" Pumpkin-Seed") have Cds on the order of 0.12.Seems like Cd 0.12 could be doable with the trailer.I intend to find out.
