They mentioned that a 'driven' tire had less rolling resistance than a 'coasting' tire (my terminology),and that over 100-mph,the Quattro actually had less rolling resistance than it's 2WD stablemate.But only above 100-mph.
How on earth did they measure this? On a dyno or something similar, I guess?

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.
