Here is Subaru's 1986 (6-model)(G) wind tunnel development model for the XT.
It measured Cd 0.088.
With the features drag of the 1999 GM Precept PNGV car,it would come in around Cd 0.095 on the street.
With synthetic vision,it would be a glimpse of the possible future,when autonomous driving is routine,'drivers' napping,being amorous,gaming,eating................. while they drive.(like they do now but minus the fatal accidents)
