*GM Aero 2003
*Renault Vesta-II
*Ford Probe-IV
*LOREMO
*Daihatsu UFE I,II,III
*VW 1-Liter 2002
*VW 1L c 2009
*VW XL1 2016
Thx aeohead. If it was part of the plan for the XL1, then that settles it for me. But Capriracer's point above that tires have less air flow exposure than we might assume because they are mostly in the wheel well... How significant, do you think that is?

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
