test drove a jku just now.... :/

Like the title says... i just got done test driving a jeep unlimited... well im not impressed... it feels under powered.... it had 321 gears... not sure how much the ratio helps... but i was just a stock sahara... im kinda bummed out... i know why people drop v8s in them now... granted i couldnt put it in 4x4 and see what it felt like.... but as far as paved road driving it dont shine there at all... which its not suppose to... but still...

What year was it? If it was pre-2012 it has the underpowered 3.8 engine. The new 3.6 engine has much more power and torque. Also the gears you mentioned don't help. I wouldn't buy a Jeep with 3.21 gears.

It might not be right for you. try the new Cherokee trailhawks. it will handle paved roads much better and is very capable as well. Just don't expect it to be mod friendly (5x110 euro spec wheels, lack of lift)... also its fwd based so switch it to 4x4 and it handles like an awd.

If get up and go is really important to you, you have to look at a 3.6 and have at least 3.73 gears, maybe 4.10's.

The 3.8 is a bit flat on acceleration, but my 3.6 feels pretty stout. And in 4lo, they get it done.

As above though, it might not be for you... Where do you want to go with a Jeep? Can a typical 4wd truck go there? If so, then maybe that's the performance measurement that you are looking for.

If you drove a new 3.6L, the engine apparently is programmed to not develop full power until a thousand or so miles of break-in. Plus, 3.21 gears are pretty much for DD fuel economy on the highway.

But, Jeeps aren't intended to be muscle cars. If you want street racing bragging rights with your buds, a Wrangler is not the vehicle for you.

+1.

I thought this was totally ludicrous. My JKU was a total dog, and once I turned over 1k miles it turned into a totally different animal.

It's still noth going to win any races, but it's noticeably faster now.

I could not keep it in 6th gear with the cruise on. I would routinely have to downshift. After 1k I don't have to downshift ever.

When I took my first test drive in a 2014 JKU I was completely underwhelmed. Felt very under powered at 60 mph freeway speeds and the automatic transmission downshifted at the hint of an incline grade or headwind. That vehicle had 3.21 gears.
I drove another about a week later with 3.71's and it felt much better.
A couple of weeks later I purchased my 2014 JKU with automatic and 3.71 gears and was happy with performance. As Up Hill Bill mentioned above the 3.6 develops more power as it accumulates miles. Mine was very "tight" when new. now at 6,000 miles this engine rocks! Good power and fuel economy.

Interesting that the 3.6 is allegedly programmed to make more power after 1K miles... I guess we have something to look forward to now.

That said, the 3.6 with the big Mud Terrains and 3.73s is more than fine for a daily driver. It doesn't have the oomph of my 5.9ZJ, but its by no means anemic.

Test drive a JKR, with the 4.10 ratio. Now if that doesn't make you smile, then maybe a Wrangler is just not the best fit for you!

The 4 door is about, 400 lbs. heavier, and with the 3.21 ratio.....Yuk

Definitely sounds like you're looking at the wrong vehicle.
It doesn't matter what engine in there or what ratio it has, on paved road it's still an overweight box with 4 wheels, almost any other SUV will give you better driving experience.

I honestly do not want more horsepower in my JKU with 3.73s. The chassis isn't designed for it. If you wring this thing out in 1st and 2nd gear, it feels awesome. Especially with the doors and top off.

The JK learns your driving patterns. The throttle-by-wire intercepts your right foot and the auto transmission shifts early if the jeep is typically driven slowly.

Autos tend to cut the balls off of anything I've driven anyway...

This one is a bit older and needs a good hood and maybe some paint here and there, but I believe the 632 CI and T400 that twists Strange axles at about 875 HP with no NOX spay may give you that 10 sec 1/4 mile feel that you are looking for. Never tried rock crawling with it though.

Or, put the top and doors on and drive it through a mudhole! Or leave the top and doors off and drive it through the mudhole and then return it to the dealership and buy another one on the lot, even better.

I smell a troll. Had many trucks with v8's before my '14 jku. It's not underpowered by any means for what it is. Go buy a hellcat if you want fast.

I went from a V8 truck to the Jeep and don't feel underpowered at all. But then again I didn't buy it for speed...

My 2013 Wrangler is one of if not the most powerful stock power plant I have ever owned and I'm going way back to a 65 Malibu with a 400 small block, stock.

I went from a r/t challenger to a 2013 jku. Its definitely slower but this jeep can go where no challenger has gone before lol

To me, the jeep is way cooler.

Yeah, if the OP test drove a 3.8l with 3.21's, I get why he's disappointed. On the other hand, Jeeps aren't exactly hot rods and coming from a more powerful car even a new one would seem like a dog. But they are designed for off and on road driving, not drag racing. I've had several big trucks with big engines. Dodge V-10, Cummins 5.9. They get up move...for a truck. My 3.6 is about the same.

Coming from a TJ with a 4.0, I'm just happy that I can pass going up hill

Well like a few of you mentioned... it makes since that the motor would loosen up and run better after it gets broken in a little... test drive wise.... like i said i couldnt put it in 4x4 and take it off road to see how the power changes once its in its element... the dealer wouldnt like that too much... it had power once it dropped into overdrive and i got on it some... as a few mentioned its not a drag car... i understand that... i wouldnt ever do trails or rock crawl with it either, around where i live its mud that i would be using 4x4 for, not climbing... thats why i said it feels slow, i would want tire spin to clear out the tred, which in 4x4 im sure itd do fine. The gear ratio probably didnt help much as what was stated 321 gears are more for the road...

its not easy to go from never owning a jeep to test driving one and trying to assume how it would end up running after some brake in and offroad... im lacked in knowledge there... only jeeps ive driven is my dads and its a old rebuilt cj with a 350 in it and racing shifter, so i am kind of partial to having a bit more hp than what i felt today with a new one... its apples to oranges... i need to take my time and test drive a diff geared one and such... we thought we were going to buy today, but looks like we need to take our time a bit more...

Kind of on this same point we have also started to consider buying an older jeep for way cheaper vs buying a new one, then slowly fixing it up too... Just another thought weve had. Get a TJ or YJ and drop a new bigger motor in it, 4:10 gears, that alone would come out ahead price wise over buying a new one, and it would have more power that we like too.. Like I said we arent looking at a jeep for trails or rock crawling or climbing, just for mud, and at the ranch...

So much to consider, but I sure appreciate yalls input in helping me think it all out!

Had a '11 Sahara and it was underpowered. Have a 13 Rubicon now wit 4.10 gears. It has plenty of get up and go.
I think they said there was about 80 HP difference from 11 to 13

Sniper .338? What rifle you shooting? Whats your preferred cartridge and twist? Have you doped to 1609? Favorite glass? Any loopholes? Always nice to meet a fellow shooter.

I was just thinking yesterday how peppy the JKU has felt the past week stripped down. Peppy as all get out, wants to go, go, go, with every shift, steering responsive, stops on a dime. Makes me really not want to mess with the suspension at all for now.
