I'd suggest that *stylists* thought it needed to go on the car, not engineers. Any 9~3 at 185HP or over will likely do the same 145-150mph top end of the Viggen and most all are sold without a rear spoiler - because aside from the Autobahn, there's not many places you can drive where the spoiler has an effect. The downforce exerted is minimal under 100mph based on what I've seen. There's just not enough pressure to make a difference. Also, I suspect that it's more than .1 mpg based on my crude understanding of airflow design. But, probably not too much more.
