Guy allegedly cuts drag coefficient from .34 to .17 in backyard


Recommended Posts

...as soon as I saw the thing I was thinking about the pre-war Nazi vehicles. Those boys did some SERIOUS work, and it was so mind bogglingly impressive (and ahead of it's time) that it went "nowhere...."

 

Then you won't be surprised to learn where the builder lived for several years, and (if it's not obvious from his photo gallery) caught the bug, so to speak.

Was that a Megaview Megasquirt Controller on the dashboard????

 

(Sorry, don't know you and can't tell if you're being sarcastic... :wink:)

 

It's a SuperMID (translated) that he added to the car to monitor fuel efficiency - a custom built unit that displays realtime & averaged fuel consumption. It was originally built & used by Prius modders (because the on-board display maxes out at 99 MPG, and many owners have figured out how to far exceed that with driving techniques in certain conditions).

 

The SuperMID has the side benefit that it can also be installed in pre-OBD-II vehicles (like basjoos' Civic) which are too old to use the efficiency enthusiast's instrumentation of choice: a ScanGauge.

 

That said, I do know someone using a Megasquirt to tune for max efficiency in an old Metro.

Wow, it's a small world. My uncle (and Godfather) is the one who designs and sells the ScanGauge. Worked at Motorola as an engineer for years, this is sort of his retirement hobby. I really liked mine, until I looked at the horrible gas mileage my Honda [Element] got the way I drove it.

 

And Woj, seriously... WHERE did you find that picture?!?!! I have two abcessed teeth right now, and that shot is the only thing thats made me laugh in three days.....

 

Google image search. Oddly enough, it took numerous queries to find a picture of a really riced out hatchback.

God that thing is ugly, but love the work he did. Reminds me of Fluids classes I took in school. Nice work for backyard engineering. I believe one day tru eco-cars will have wild shapes and just be standard for the public. With the rate gas prices are going, plenty of people will pefer cost/function over beauty.

 

Given how current cars are looking, the Camry for example, this Aero Civic at least is interesting.

 

Given the choice for a daily driver, I'd take a vehicle that looks like a '50s future-mobile, tear-dropped and very smooth. Driving to work, school, errands, who needs anything other than mileage, safety, reliability?

A slight diversion :

I read about this car in a "Car and Car Conversions" magazine about ten years ago. Claimed CD is 0.24. Original car had a massive off around a corner which ripped the driveline out of the car, and was then rebuilt.

 

Web site is here.

I think he could have started with a better base (like a CRX HF) but if it's what he had then it's what he had.

 

Do I think it's ugly? Of course.

 

Do I think his efforts were pointless or without meaning? No.

 

What if he's on to something? For all we know we might end up seeing hundreds of college projects of people modifying their vehicle for the sake of science and better mpg. His project should inspire people to show them that it doesn't take time and money to make a difference in their car, it takes WELL THOUGHT OUT EFFORT.

 

He's not really much different than any of us here, just a TOTALLY different goal in mind.

 

If his car ran a 6 second 1/4 mile we wouldn't care what it looked like.

You know it's still surprising to me that people here in the bay area continue to buy huge SUVs and trucks when they unquestionably don't NEED them.

 

Who knows what the public will really buy in the future. Overall they're a mass of unpredictable and unintellegent buyers.

CRX HF Aerocivic FTW!! if he did THIS to a standard civic hatch, then the HF engine and driveline, combined with that ultra low weight vehicle... and all these mods?

 

That was all I could think of the first time I went through the pictures. My little bro has a CRX HF that was his first car that he has turned into a ratty autoX/street machine with an SI engine/trans.. that thing is about as quick as my stock 280Z was, and DEFINITELY quicker through a turn.

 

To me, the CRX HF represents a pinnacle of "on-the-market" automotive engineering.. a very humble and minor pinnacle, but its one of the more significant peaks in the mountain range IMHO.

Hi guys -

 

Name's Darin. I'm one of the admins at Ecomodder, where the Aerocivic thread is posted.

 

I just had to register to say this: of the couple of dozen "enthusiast" auto forums that have picked up the Aerocivic for discussion, you guys take the cake - I'm genuinely impressed by the quality of the comments here.

 

You guys "get it".

 

The majority of the other enthusiast forums can't get past sniping about the workmanship & aesthetics to get to the salient points.

 

I tell you, if I were into Z's, this is the forum I'd pick. (Last time I was in one was for several instructional & track days at the now defunct Nissan School of Performance driving in Shannonville, Ont.)

 

Cheers!

 

 

rofle.copter.

 

I was about to just say "whytf is this conversation still going on, seems like lately a lot of ideas new to this forum get turned into political debate and just stray way off topic and blah blah blah" but if this dude is registering to congratulate us for it, bitch on at each other, guys! lmao

 

edit: thank you Darin.

nice, but i call bs on the original mpg. i have the 93 civic (bare bones model aka cx) and it was all stock and driven to get the most mpg out of it and i could only achieve 45mpg at the most. now mind you that this is in perfect working order and using the most lightest oils and even compression across the boards. (basically a new car that was broken in) now he claimed 50 to 60mpg stock....BS. i need real data from when he achieved that and how the hell he did it. if he can prove that... i will believe the rest. in my eyes anyone will try to get their 5 minutes of fame... and I'm not buying it without hardcore data to back it up. and this doesn't matter how ugly it is.

:wc:

he never said pre modification.. he said, "before I started Aeromodding it"

 

He also said that the worst mileage he had gotten was with snow tires, in the snow, at about 35 mpg.

My car is a 92 Civic CX, which I bought new, and was giving me low 60's to low 50's before I started aero modding it.

....

Approximate mileage on a flat road at 85F, 95mpg at 30 to 65mph, 85mpg at 70mph, 65mpg at 80mph, 50mpg at 90mph.

Something is telling me this is one of those guys who drives like he has precious eggshells between his foot and the accelerator pedal.

 

 

And for the love of mike, tone it down, brother! TeamNissan pointed out plainly and simply that these guys have computers that are telling them ON THE FLY numbers for their fuel mileage.. I somehow got the impression that the ~90mpg figure was a maximum figure attained on a digital readout, NOT an average from a 500 mile trip.

 

There is no reason to "call BS" on these guys; if you would read through the thread impartially, instead of letting your experience blind you to the data they are trying to present, then you might notice more details.

Both you guys better check the attitudes or you'll both get a time out of the temporary banning kind. Got it?

 

I owned a 1990 Honda Civic HF and registered 47mpg for two years straight when the car was tuned properly, tires inflated to proper pressures and I was mindful of the gas pedal. I know a thing or three about this particular base model car, because I was stuck driving it for several years as a "second" car. Furthermore, my father, who is my personal hero, registered wel over 50MPG regularly in a Ford Festiva on a very frequent basis. Say what you want, but there are people out there who do what they can to get from point a to point b. They do what they can to stretch a buck and getting great fuel mileage is one of the many. You guys want to debate that, do it elsewhere... The source of discussion here did great things, and some of you are pissing on his design for the sake of what, style???

 

I believe the numbers could well have been recorded, but hey whatever...

Our Mileage Competition VW Ghia got 52mpg. The Corvair was in the high 40's...

 

I wasn't being sarcastic, I was curious what it was on the dash...it looked like it may have been the Megaview Electronic Dashoboard and the display was unfamiliar to me, so I thought it may have been a new format I was unfamiliar with (and which I wanted!)

 

So it's a different gadget altogether. Hmmm, something else to investigate. LOL

 

Ask anybody here.../sarcasam on/ I'm never sarcastic! /sarcasam off/ LOL

 

At least not in this instance!

Just to throw a little fuel on the fire, I can confirm (though I expect I'll be considered a liar) that, under ideal, moderate freeway conditions a '93 DX can consistently knock down upper 40's at 62-65 mpg. Early summer cool dry weather, lightly loaded, perfectly tuned, pure freeway conditions with cruise control engaged.

 

I'd like to put my vote on the "style" of the the thing as "elegant in its' purity". Can't you just picture the airflow around the thing? Its design is as single-minded as a stiletto, and just as graceful.
