Civic hatchback aerodynamics

[Compaq888]

I wish I had 2 cars. One for daily driving(interior gutted, no PS, weight reduction, Scangauge 2, aero mods) and another car to take dates, go to movies with friends and etc.

This should be a number one weight reduction item. If you have a garage to store it (no long haul to put it somewhere) and a quick-release rail system, removing it for the weekly commute would be very convenient. My Saturn uses 4 heavy bolts to connect the seat, so I would have to retrofit a slider system. I have removed the seat for moving in the past and I like the roomy feel of the interior without the seat, so it's a definite plus.

The sliders already exist for after-market seats :



Does the Fit have removable rear seats?

So far (at 210miles) my gas gause is much higher than it would normally be with this many miles on the tank, despite 120 miles of driving in rain and wet roads. The tail end of a 2 mile long coast on my way home from work really drove home the overall improvements that the aero mods have made to my car's coasting ability. At the point on the road where my car's speed would normally have dropped down to 35mph in its pre-aero days, I am now doing 50mph and I can roll on for another quarter mile down the road before I have to restart the engine.

Eagerly looking forward to your next fill-up basjoos.

Man, if only our cars had such a boattail built into them.

Te auto industry clainms going aero would reduce storage space, but that clearly is a crock of ****. Your design could have easily been incorporated to double usable trunk space while perhaps improving FE by 15%.

If you get 80-85 mpg highway, I will not be surprised.

basjoos you are hardcore. I hope you see a big gain.

I like what basjoos is doing for sure, but if the long term average from that boattail alone goes from 70 to 80-85 I would be surprised.

Time will tell.

Yeah , you could easily fit a body in there now , err , I mean , all your shopping

[thisisntjared]

i think it could even be more streamlined, the plastic behind the extends from the side windows should be angled in closer. that mid frame should be like a trapezoid instead of being a rectangle. i bet he will get great gains, but its amazing that there is still more!

My tiny kardboard Kammback (I know it's not technically a Kammback ) netted a 2.3% gain @ 55 mph. I can't estimate what basjoos' full tail will yield, but it's going to be way more than that.
