Meaning of Aerodeck

[Ricarlos]

Hello guys,

We were guessing on a french forum what is the meaning of our beloved "Aerodeck"

Can anyone enlighten us about this?

ThX!

[charliekuney]

Probably because there is an "aero" view from the rear "deck". lolz

[Legend_master]

I think it's actually the aerodynamic shape if the back.

[charliekuney]

Meh, all models had incredible aerodynamics for their time. I'm sure the Aerodeck's drag coefficient is the same as our hatch, or slightly worse.

[Vanilla Sky]

I would say that the Aerodeck would have a lower drag coefficient due to its design. Kammback - Wikipedia, the free encyclopedia

[charliekuney]

Aerodeck isn't a Kammback as far as those go. Square like a van = bad. Kammback is like halfway between a notchback hatchback and a fastback hatchback. I don't know, I don't have a degree, but it my head it makes sense.

[Vanilla Sky]

The Aerodeck is a kammback design, though.

Either way, who here doesn't want to get their hands on an Aerodeck? If the pricing were right, I think a lot of use would be seeking one.

In general, a squared off back is not aerodynamically ideal. A back that tapers down to a point is best, ala a "fast back." Of 3g's, the hatch has the lowest drag coefficient. I'd guess the Aerodeck is probably the highest.

As far as I can tell, "Aerodeck" is what they call station wagons in EDM land. I wouldn't say that our term "station wagon" makes any more sense.

It depends on the treatment of the trailing edge of the vehicle. If there's an air pocket that builds back there at speed, then the air is going to go over it just like it would if there were bodywork there in place of that air pocket. That's why most high MPG hybrids use Kammback designs. Now, if the rear just ends with no attention paid to what's happening to the air back there, it can cause all sorts of issues. Given how low Honda managed to get the C/D of these vehicles without the instrumentation and testing procedures available today, I can't help but think these cars spent a really long time in a wind tunnel, testing as many different variables as possible.

Everything I read says that all the models are the same drag coefficient of .34 (which is damn good). Looking at the profile view of the aerodeck the whole back deck slants downwards to hatch. I'm thinking that is the name breakdown as they have a civic aerodeck with the same sloping roof design.

[charliekuney]

I've read .34 for the rest and .32 or .31 for the fastback hatch!

Wonder if there is a difference between the front bumper covers (prefacelift)

[Dr_Snooz]

Okay, let me call on myself. The hatch has the worst aerodynamics at 0.34 CD. The sedan gets 0.33 and the coupe is best at 0.32. The link below will give references for anyone interested.

According to our good friend at Paul Design (ABOUT HONDA ACCORD - HONDA ACCORD AERODECK 1986-1989), the Aerodeck is also 0.34. So whatever.

[charliekuney]

Your link also states that the coupe is a 2+2, which it is not.

[Legend_master]

That could be a bumper design issue as well. I don't think the hatch or the aerodeck ever came with a facelift bumper. Charlie I thought 2+2 was 2 seats in the front, and 2 in the rear?

[charliekuney]

2+2 is two seats in the front, two in the rear. Like the Prelude. Accords have three seats in back.
