I've never seen a specific breakdown.The really high mpg/low drag concept cars are lowered with active suspension,so they can still negotiate driveway ramps and such.They tell you what the Cd is with the "drop",however do not provide Cd for "street' configuration.If you want to slide your car under Darin's teardrop template,you could probably calculate the difference in virtual wake area,with and without the drop.Any 10% reduction in wake area would yield a 10% drag reduction,and 5-6% better mpg,at 55-70 mph,respectively, do to fineness-ratio alteration from drop.Search for" permanent Metro Kammback" to find Darin's template.
