Chops....You're under the common misconception that there is something you can do about the "Vacuum" behind your cube shaped mode of transport. Well, All vehicles have to deal with this, and it has to do with the overall cross section your car presents. The difference between an aero shape, and one which isn't, has to do largely with how this air is managed after it makes it past the "Fattest" part of the car. More aero shapes tend to come together gradually after this fat part thus allowing the air to make a gradual transition to what it was doing before you violated it by ramming through it at high speed.

So bottom line, your Cube creation does very little to ease this transition. Any thing the air tabs may do to "Break the Vacuum" will be more than off set by the drag created in producing the effect.

Air tabs may have some effect on Very specific automobile shapes, these shapes would be ones which the flow separation occurs due to the rear slope of the vehicle being just a bit too much for the flow to remain attached. These vehicles are not common, and your Cube is clearly far outside this group.

You have a wicked cool car though which is maximized for interior space for the size that it is. Enjoy it just the same.
