Did this really quick at work...
Subuaru claims that the WRX/Sti sedan is more aerodynamic than the hatch by 0.1.
Sedan = 0.34 cd
Hatch = 0.35 cd
I did a quick streamlining template of the hatch vs sedan. Now i can see why.
It appears that the STI wing (no matter how gaudy and huge it is), it actually follows the aerodynamic streamlining template a lot better than the hatch.
It also appears that the hatch drops off to sharply in the rear, hence it could explain why it's cd is slightly higher than the sedan
Subaru claims that the extra 0.1cd reduction in the sedan gives the sedan a higher top speed of 155 vs 153 of the hatchback.
