lol well that's the whole point really.

It's slow when you compare it to more performance geared cars and SUVs but I'd like to see some of those "performance" SUVs go off road like the JGC.

What I tried to mentioned earlier is that it's not really a slow poke but it's definitely not a super fast SUV. It's a great option for someone who wants comfort/luxury, basic off-road ability beyond what most stock SUVs offer, and a reliable vehicle.

Even if you tried to tune the engine, I don't think you'll get much out of it since it's N.A. engine. Not without spending oodles of money at least. Easiest bet would be to throw in a supercharger. Which we all know is not really and "economical" option. Let's face it, putting in a chip and getting 10-20 extra bhp is not worth the money.

I agree that it's silly to compare vehicles that are meant for different purposes but unfortunately the JGC is being pegged against X6s. I'd see the comparison for X6M and SRT8. But the hemi isn't really going to be the "powerhouse". But, here's the question...why would you want the set up for the JGC overland to perform that way? I wouldn't trust it on bends at high speeds. Unless you want to drag. In that case, save some money and get an SRT8.

This whole idea is like saying "why is the Golf GTI so much slower than the BMW 1M?" Well... 1) look at the insane price difference 2) look at the market of buyers

They were definitely built with differ priorities (1M is more performance tuned and less everyday driving in my opinion and the GTI is the other way around). I've seen this comparison many times btw, as I have with the JGC Hemi and the X6.

Just my $0.02

EDIT: I know price difference doesn't necessarily mean a better car or faster car but generally, it tends to point towards the brand and most of the times it does equal to better performances (of some sort, maybe BHP, maybe top speed, maybe luxury etc)...again not a rule of thumb, but does have a generalization behind it.

The 2014 5.7 is nice, and can easily cope with 10-14,000 foot mountain grades.

However, although the power and torque figures [adjusted for the difference between modern and '60's SAE versions] are quite similar to a '66 427, it just is either too heavy or the horses are far too housebroken.

Wonder what it would take to camouflage a 6.4 or 6.1 and stuff it under the hood, but keep the 5.7 warranty.

Re: 2014 V8 is weak?

The engine has the power but everything else makes it slow. That's why I bought the v6 lol. I do miss my g8 gt with the 6.0l

Despite the lack of performance the fuel consumption is excessive averaging over 17l per 100kms. After researching Ecu upgrades it has turned out there is nothing on the market for my model and if you are outside of the US forget about it regardless of what model you have. All in it is a good car but it has nothing on the euro equivalents.
My 12 WK2 5.7 gets 11 L per 100 Km highway and averages 13 to 13.5 L per 100Km combined city and highway. There are several different tuning options available from companies like Diablosport. I wanted better throttle response in mine so I installed a sprint booster. the lag in thrust after you hit the gas pedal is gone. It feels way faster off idle and is much more fun to drive.

Re: 2014 V8 is weak?

I am currently driving both an '07 WK 5.7L and a '14 WK2 5.7L.

I don't find either "weak", though they are very different.

One of the things I dislike most about the '14 5.7L is the way it meanders through the downshifts when you mash the loud pedal while underway. The ZF trans is alleged to be able to go straight to any gear - and given that I just pushed the pedal to the firewall the PCM oughta know what I want, yet we take our sweet time, trying every gear along the way like Winnie the Pooh is in charge...

But the launch throttle lag is much less of a problem on the '14 than the '07...

^^^ My 13 5.7 seems to have gotten better as time/miles go by. How many miles are on yours now Tom? Still going ta invest in a tune when available though ... !

Hi SLGF. I have done some research on tunes but as far as I am aware their are no tunes for a 2013 or for export models. It would be great if this is not the case as I feel there is a lot more potential in these engines but they are held back by very conservative tunes.

I suspect that in Australia Jeep may detune the cars as the performance figures quoted on the Australian Jeep website indicate a 0-100 time of 8.6. I thought this must have been a misprint as members on the forum were quoting times of 6.8, after delivery of the car delivery i realized this was not the case.

Is the downshift any better in sport mode?

I don't know why its considered considerbly less than its euro conterpart. There really isn't a euro conterpart. Maybe a Range Rover sport or an LR4. I had a brand new 528i as a loaner when I went to test drive my jeep. Granted its car vs. SUV, I did not find anything wrong with the jeep at all going from one to the other. I considered an X5 since I had a few BMWs already, but it rides too stiff and costs about $60,000 to be equivalent to a $40,000 limited. It has some minor fit and finish advantages, but not $20,000 worth. Also looked at the Range Rover sport. $70,000 to be equivalent to a V8 Overland. Also not worth it at all. I'm very happy with my Limited. First new American car in a long time. Very happy.
