On a sidenote, did that aftermarket antenna improve radio reception? I just can't get the radio to come in very clear on mine.
If it were for the panel gaps only, then yeah, not worth it.
However the VGs had shown to improve efficiency of spoilers, so without tests it is hard to say if they will improve or hurt our car.

Though comparing our roofline to the rear end of a Lancer is definitely apples to oranges, considering the Evo wing/VG study is looking at air flowing over and under the wing, and hatchbacks don't have trunks.
Agree hatchback is more similar to tractor trailer or wagon. Read this:

Not sure if this has been discussed before. One of the aerodynamic quirks of Mirage is the A-pillar placement. It looks like car is the widest at that level at A-pillar.
This pushes air over the roof and reduces side flow. Better aerodynamics, less wind noise with windows up and down.
Bringing this back for discussion (This is actually x-post from Prius C bad highway MPG thread at ecomodder):
=======================================
So got to travel on the same road in very similar conditions (load, temperature, wind, etc). Once again using cruise control to take driver out of consideration.
Computer calculated MPG was 41.4 vs 38.7 last time, this is average over almost an hour (had to abandon test after ~50mi as we ran into construction zone with lower speed limit). 7% improvement.
Difference? A set of EVO-style vortex generators installed alone the roof trailing edge.
I am building the underbelly panels when it warms up.
==================================
Prius C computer collects the MPG data on monthly basis, and the data collected in past 4 month seem to confirm the trend, though they are too imprecise to use in calculations. Since car gets ~2,300-3,000mi a month, this is result of ~11k worth of miles.
Also it looks like my suspicion is correct, and Prius C aerodynamically slightly worse than Mirage, despite both rated at 0.28 Cd.
cyclopathic, are wind speed and direction being noted in your data?
