Probably been there for a while, but the EPA has the Emira in the spreadsheet of data they release :
www.epa.gov
I didn't know before today that they include info that allows you to calculate total drag vs speed. Plugged the numbers in for the Emira (only set of values except for the cold ones - so guessing it's the goodyear tires).
Interesting that the GTS4.0 appears to have lower drag at higher speeds, but starts out about the same as the Emira. Better aero? Just as a comparison, the BRZ is about 165 lbs drag at 80 MPH vs the Emira at 190 lbs. Oddly though the EPA rates the 2 cars at 16/24 and 17/24 so I'm curious as to how accurate these figures are. Is the Toyota 3.5V6 that much more efficient than the 4.0 at highway speeds to overcome that drag delta?
And looking at it vs Horsepower required (drag data * speed) :
