JohnPr's jeep aero mods

[me.facePalm()]

Not gonna lie I think that wasting 0.001mpg more gas is worth not looking like a tool. Nothing you do to a Jeep will increase gas mileage significantly. If this is what you are concerned with there are plenty of hybrid suv's out there that you don't have to make look like a space ship. I know that Wrangler is a "cool" status symbol but dude, if you aren't going to use it for what it's made for get a cheaper suv that is better on gas. There are plenty of suv's that get upwards of 25mpg (jeep gets 15...maybe) that don't cost $25,000-$30,000. Wrong tool for the wrong job. This is like using a laptop computer to hammer a nail. It doesn't work like that.

You are clearly on the wrong forum.

No, he's not.
It's all about picking the right vehicle for one's needs.
That'll mean the vehicle can do what it has to do in a most efficient manner.
It's the most important fuel efficiency mod one can possibly do.

His point about vehicle selection was reasonable. But a notable percentage of all posts here on EM are goofy looking aroe mods with minimal gains (and that's how I like it).

It's the attitude that reveals the poster is on the wrong site. From what I can tell, it's what you do with what you've got that matters, so berating someone for their vehicle selection is contrary to the spirit of this site.

What jeep do YOU drive? my I6 powered NO aero mods LIFTED 4" 31" mudders 88 Cherokee with 496,000 miles gets 22mpg on my daily commute and I have hit 25-26mpg on pure highway driving.

at least when I have E0 for it. subtract 20% with E10.

you are CLEARLY on the wrong site if you think buying a hybrid is the solution to ANYTHING except that of emptying your wallet. it will never ever pay for itself in fuel savings. not one penny.

I drive 40k a year and a prius would take 68 years just to break even assuming I put NOTHING into it in that 68 years. thats a lot of miles. I don't even think the CHASSIS would last that long not to speak of all the moving parts.

[alohaspirit]

wow, 40k a year

it would take me over 6 years to rack 40k



but look into trackers and sidekicks (zukiworld.com)
they like building them up for about $5k and then outperforming $25k jeeps on the trail
mine gets 24mpg in town driving

[comptiger5000]

Facepalm - Very few Jeeps are bad enough to get 15 mpg on the highway. I have broken 21 mpg highway in mine, and it's got a massive, gas sucking 5.9 liter V8. Plus, a Grand Cherokee is bigger and heavier than Nerys' Cherokee. Oh, and this is on E10.

[Nerys]

yeah on E10 I get 19 if I am lucky :-( horrible horrible stuff. I think part of it is the ZJ is a little more aero than the XJ (they are freaking bricks :-) and I think they are geared lower but i love how small and nimble they are.

mine is a very capable offroader (that actually DOES GO off road) that also makes a nice looking and comfortable daily driver (not any more :-) can't afford to fill the tank twice a week anymore :-)

[comptiger5000]

The ZJ is a bit more aero, with a .45 cd vs .51 on the XJ. However, the ZJ has a bit more frontal area, so I think it's about even in the end. The top gear in the ZJ tranny is a little taller, but the V8s have slightly lower axle gears than I6 XJs or ZJs, so the difference isn't much (with 245/70R16 tires, it's a difference of 1815 rpm vs 1760 rpm at 60mph). Plus, I'm handicapped by an almost 50% larger engine.

I think it comes down to the Renix EFI on your '88 being more sensitive to E10 than most. I've never had an opportunity to run mine on E0, so I don't know how it compares.

I agree on the capable offroader and nice DD combo. The ZJ is a hair less nimble than an XJ, but not by much. It still handles pretty well. Fortunately, I don't drive enough for the fuel cost to kill me. Up here in college, I've been getting 1 - 3 weeks to a tank, rather than 6 - 10 days at home.
