test drive v6
 
I currently have 2004 Overland 4.7HO and I love it. But I am very into the "new" Overland... Can not decide on the motor yet. Was not able to take it for a ride( dealer is keeping it in the showromm only) but I did test drive Limited with V6. It was bit slow from the line. I am not sure if something was not right with the transmission or this is the way they ride. I was not racing it but I had to push the pedal over half way down to make it move and keep up with the trafic. It was shifting at 3,500-3,800RPM's and was working hard. When driving with 60mph and pushing down for passing it was down shifting and reving with same high rpm's. I drive my 4.7 with same style without pushing over 3,000rpm. Was there something wrong with the Jeep? If you don't pay attention on the engine rev's the ride was perfect and soft. Steering was little hard on moving the wheel but it was fine for me. I will take the 5.7 for a ride next time to compare. Maybe if the 3.6 has the 8 speed trany will be different story. What do you think?

What you encountered is accurate. That's why so many of us have been hoping for an improved transmission and a few V6 power/torque enhancements for the 2012 model. Alas, it turns out that this may not happen until the 2013 edition.:(

The V-6 engine is a spinner, not a grunter. That means in those instances where you're flogging it for more power for passing, it has to kick down and build revs.

I've put 4000 miles on my V-6 Overland, including a drive through the Appalachians. Yes, when you need more power you need to get on the throttle. It isn't so overpowered that a breath on the accelerator will result in stump pulling torque and power. It's engineered for smoothness, which means you need more pedal for more power; it keeps things from being jerky from a stop. I've been in vehicles with aggressive throttle calibration; they sure feel powerful but they are hard to drive smoothly, especially in poor weather.

IMO, the behavior of the V-6 is exactly what I expected. If you want a more torquey engine, there's always the Hemi, but keep in mind that they were pretty conservative with that throttle calibration too- it doesn't feel that much more powerful off the line.

Techno is spot on here...

I just moved from a 2007 GC Limited with the Hemi to an Overland with the V6. I did a little review:
http://www.jeepgarage.org/f73/initial-thoughts-2007-wk-hemi-to-wk2-pentastar-14222.html

In general, the V6 is not designed for the power hungry. Yes, I think a new transmission with a lower first gear will give you a bit more pick-up at the get go, but the V6 does have some get up and go... when you ask for it. And, the current transmission is tried and true! It's part of the reason I went with the V6.

I suggest test driving both, and then choose in regard to your individual needs (and desires! :)).

Thank you all for the replays. I will be testing the hemi this weekend but since I do not tow or go off road alot I may take the V6. What is your MPG with the 3.6 when you push it little harder? With my short test drive on it I got 17.2mpg on a two lane blvd. with several traffic lights. To compare I am getting average 14.5~15mpg on my '04 Overland with 4.7HO with mostly short trips with traffic lights. This summer when i was in Europe I drove my frend's 2003 Jeep GC Limited with 3.0 diesel. It was better than the 3.6 from the line and was getting in the city average of 19mpg converted from l/km. By the way most jeeps there were diesel!
Wish they make it like the new BMW X5 with 3.5 diesel and 8 speed trany.

The V6 and 5spd is an excellent combo, IMHO. I just test drove a base Laredo 4x4 V6 last weekend and it was a LOT more than the typical around-the-block dealer ride. A friend's friend manages a dealership and they use the 2011 Laredo as a shuttle or loaner or whatnot, and it had over 1200 miles on the odometer when I got into it. It was very well-used inside, scuffs here and there but it wore the usage well, if you know what I mean.

The acceleration off the line with the 3.6 is certainly not V8 punchy but rolls on steadily all the way to redline; it's linear like a German powerplant and I like it. In comparison, the Hemi I tried a few weeks didn't exactly launch that enthusiastically either. I think they programmed the throttle to open slowly off-idle whether or not you floor the accelerator or press into it. One thing I tried off the line was very slightly throttling up while holding the brake and then launching...it made a big difference. I wouldn't do that often as it is extra wear&tear on a transmission.

Before the dealer manager and I went on our 44 mile test ride (we even went into a field, no mud though), I reset the fuel economy and trip meter readings. We slugged through some construction-zone crawl, hit the interstate for a bit (the avg MPG was at 25+ MPG and climbing on the interstate after ~10miles) and then went into a farm field trail. We hit a few curves, railroad tracks and some nasty cratered roads before venturing back home.

The base Laredo 4x4 handled all the bumps and ruts very well, remaining stable and quiet. In fact, the V6 is so quiet that the lack of visceral sound may make one think the vehicle is really slow; it isn't for what it is. I tried two 0-60 runs and we were just a tic over 8 seconds on both attempts. It's faster than my 2006 5.4L Ford XLT 4x4 Expedition for comparison. The transmission never felt slow or lazy and it readily kicked down when throttling up for passing.

Now for the interesting part. When we got home the computer was indicating an overall trip fuel economy average of 23.1MPG over that 44 mile run with a mix of mashed throttle and ~20 light-footed highway miles. Given that a vehicle computer has a propensity to overestimate by 5%-10% from actaul MPG, I was really impressed as I was expecting something pathetic like 14 MPG.

Unless you need the towing or that 1sec less acceleration time to 60mph, I don't see a need for the Hemi. Want....sure....need...no.

Diesels tend to be pretty torquey since they're usually very undersquare (more stroke than bore in the engine- they just don't spin very fast, but dang if they don't have some twist, and that torque is what you feel off the line).

I got about 21.5mpg on that 2000 mile trip. Not bad for a green engine and running a pretty constant 80+mph. I expect things will settle in to about 23mpg or so highway. In town, I think I'm probably getting about 16-17 or so. More or less right in line with the EPA estimate.

What's really sad is that these 10 year old parts bin Mercedes 5-speeds are choking the hell out of both GC engines. The gear ratios in 1st, 2ond, and 3rd are similar to the old 1980's 3 speed automatics. Chrysler/Jeep better get on the ball because the word is starting to spread.

The Mercedes transmission is only mated to the 3.6L. The only reason why they're still using it is contract agreements. They have to buy a certain amount of them, and this has been going on for years.

Hello,

I have the Overland with the V6 and recently towed my 4,500 lb. Airstream trailer down to Cape Cod. I have the brake controller and a Reese WD setup for the trailer. Yes, you know the trailer is back there, but I can say that the setup is fine for this driver. Averaged 14.7 mpg on the trip which was about 260 miles round trip with about 60 miles rolling around the Cape (like city driving). Pulling unto the highway you did need to mash the accelerator and it took a bit, but was a steady progressive that I am comfortable with. In my various renditions of RVs, I have had the truck camper, several class Cs and two different Class As, so my expectations are a bit different than yours might be. Also, as I only pull this trailer and a snowmobile/ATV trailer less than 25 % of the time, I find the other times that the V6 is very adequate. I agree with one summation in that the Hemi motor is different and seems to be quicker off of the line.... but not a fan of that over the last few years unlike my 19 year old who has loved all of our various Hemi equipped trucks and Jeeps.

Sometimes I wonder just how many people who gripe about the W5A580 transmission with the Pentastar have actually, you know, DRIVEN one. Seems to me to be a lot of complaining with precious little grounding in reality. So the V-6 won't push the Grand Cherokee to 60 in sports car time. Big deal. It's plenty good enough for what it needs to be.

Im coming out of an x5 4.8. I test drove both the Hemi and the Pentaster...asi really wanted to go for a 6 this time. Unfortunately, I found the Pentaster undrivable.
