my jeep's new aero mod
 
2 Attachment(s)
ok so i had a long trip last weekend and said to myself, "john, you drive a brick, lets see if we can't make it any more aerodynamic" i had already left the house and didnt have any tools with me so being the problem solver i am i found the nearest snow bank and proceeded to ram into it (ok not really ram but more of a drive into at 15mph) i came away from the snow bank with a giant block of snow sitting on my front bumper and spent a few minutes sculpting it. long story short i ended up wit a wedge shape ontop of my bumper, the next morning (after having already arrived at my destination) i was surprised at how much snow was left on my front bumper and thought some of you guys might get a kick out of it. honestly it helped my fuel mileage tremendously ( a trip which normally takes around a quarter of a tank only took a little over 1/8th so not bad. :thumbup: as you can see from the pictures the snow did wear down quite a bit so it wasn't consistent for the fuel savings.

now kind of along those same thoughts i have been considering making a new front bumper and grill guard that would be aerodynamically shaped and have a removable Plexiglas shield. any thoughts?

That's funny. :)

You probably slightly improved the shape of the front of the Jeep, but more importantly you blocked a lot of unnecessary airflow through the grille - probably the biggest benefit.

Do you keep track of your fuel consumption tank by tank?

More Jeeps?

More Jeeps! You guys have to start doing your fuel logs. I want to know who's winning. :)

in my 20 gallon tank i average 350 miles, that little aero mod didn't last a full tank so i cant give a full tank measurement :(

MetroMPG 02-21-2008 05:22 PM

What I was wondering was whether you keep a record of each fill up. Not for this mod specifically.

BrianAbington 02-21-2008 06:01 PM

maybe we can get a sticy thread for us to log our fill ups.

MetroMPG 02-21-2008 06:04 PM

That's what the garage & fuel log is for!

well I am new here...sorry

it's fine, seems that you've found it anyway. With my 23 gal tank I can average about 21, which equals about 480 miles per tank, but in the summer I can go over 500, but it's sadly not summer :(

As fuel usage goes down, and Public awareness goes up, We (every human being) all win in the long run.
I'm in this for the long haul.
I know you were just pokin fun.
I'm just happy knowing I'm not the Lone Deranged-er any more.
btw My kids still think I'm insane.
You shoulda seen the look on each ones face the first time I shut down the engine while driving. Only my Grandson thought it was cool.

one of these days i will start my fuel log again but im sure that DPoV wins hands down, both of my jeeps are soft tops, have a decent amount of ground clearance and are modeled after bricks. so what im saying is: a brick with a kite attached doesnt move efficiently. hmmm, at least i recycle :P . anyhow on a more serious note, im thinking about making an electric 2 door off road vehicle with better aerodynamics (but many of the same features) similar to the jeep. main differences being sloped front end / and windshield and a fastback hard top.. any thoughts?? (ill have to post a picture of what im thinking one of these days with some more details)

Very cool idea. Pun intended.
Take a look at my front panel pic at left. Similar idea.
Doesn't melt though.

that looks great, im not in rambling mood today so no long incoherent post (yet lol)

Somebody should PhotoShop up a Jeep with the basjoos treatment.

DifferentPointofView 02-23-2008 02:21 PM

If anyone wants to use mine I wouldn't mind lol, cause I Don't have photoshop, I'd have to use paint or draw it myself.

snow-bank aero-Jeep
 
I love it! And with some fruit flavoring,its edible too! My neighbor has a C-J,and it has a lot of gaps which allow air to go between the fenders and grille,and without an airdam,the air collides with the front tires,chassis,and suspension components.Quite a torture-chamber under there.And as Darin has pointed out,you probably managed to block some of that flow and get it to flow"outside"the jeep,where its got a clean shot to the rear.You might duplicate the effort with cardboard and duct tape.Also,if you could develop some curvature around and over the roof I think you'd see some additional benefit at the gas pump.The flat plate that the windshield is mounted to has a drag coefficient of 1.17,almost as high as that of a parachute.You'll notice that the Jeep Liberty has softened leading edges all over it's front end,and that really helps stretch it's fuel.Love the pictures,good luck on the project.
