Unless in sport mode, it always starts in second gear, even with ECO off..so obnoxious. Sport mode is incredibly annoying. nice that it starts in 1st, but will hold second gear at 4k RPM for an annoying length of time.

Anyway...enough ranting.

Has anyone owned both the V6 and the V8? I've only briefly test driven the V8. In real world usage, is it as infuriating as the V6? I'm hoping the V8's torque makes the driveability a bit better, or the transmission actually made by ZF acts a lot better.

Any input appreciated! Almost bought a GMC Sierra until I figured out that it's too long to fit in my garage!

Also...anyone want to trade?
I have a 2015 Summit V6 and I agree with much of what you are saying about the performance. I initially thought the V6 was a dog, but after I realized how much the throttle limitation software impacts the driving experience, and creates the horrible lag on acceleration, I've decided the engine isn't really to blame. I believe a 295 hp engine is plenty to get this beast up and moving quickly; it could have a bit more torque but it should do the job well. If they would go back to the old throttle by cable, instead of by wire electronic, along with ditching software limiters I believe the V6 would be a complete 100% different driving experience.

We still have our old 1999 JGC Limited with the 4.7 V8 (and throttle by cable) and the hp in that rig is less than this 2015 V6, BUT the torque is way higher so it just smokes the new V6.

My rig had some of the 845RE tranny issues on the 2-1 downshift, but the dealer loaded the TSB I found and it really helped a lot. I don't really have any complaints about the tranny anymore, but the low torque and throttle lag makes me want to trade it for a Hemi or Diesel. I can tell you this - if I were to buy another tomorrow, there is no way I would buy the V6. I drive much more in town than highway, and my mpg is averaging around 15, so I'd take a few less mpgs for the Hemi power any day of the week.

I drove the Hemi along with the V6 before I bought mine, and I really thought the V6 was VERY peppy so I focused on saving the $$ and getting the V6, but doing it all over I would go Hemi or Diesel.

Do keep in mind that the MY12 and MY13 V6 JGCs you owned didn't have the 8-speed transmission which most folks state makes a big difference. That's not saying there isn't a delta between the MY14+ V6 and the V8, but all indications are that it's not as pronounced. The V6 with the earlier 5 speed didn't perform as well as the V6 with the 8-speed.

Re: Hemi vs. V6 driveability

I test drove the diesel ('15), and purchased the Hemi ('15) after my wife test drove the v6 ('16) with me in the vehicle and said it felt slow.

If my wife says it feels slow, it's slow. She used to own a Chevy Spark, and now owns a Prius C. I'm sure it's faster than those, but if that's her point of comparison... just saying.

The V6 is great for the MPG, and it's cheaper. Calculate how many miles you drive, and calculate the gas costs between them. If that number is too big for you then choose the V6. I think it's that simple. The Hemi without a doubt will be more spirited and fun to drive, more capable, and sounds/feels like your driving a pretty strong machine (sexy beast i say.) but if the cost is not worth it it's just that. Not worth it. Your call

I had a August 2013 built 2014, 2015 and 2017. All transmissions were fine. 2014 had fairly serious shifting issues until the firmware finally fixed it in Dec-2013. 2017 is slightly more spirited.

I am not so sure the vehicle sticker is a reliable indicator. Here's an older car with allegedly the same 8 speed transmission and a Pentastar.

That's because her V6, with the 8-speed will run neck-and-neck with your older V8. Sometimes people don't realize just how much performance you gain with an 8-speed transmission. It really keeps the engine in it's sweet spot.

Re: Hemi vs. V6 driveability

My 17 V6 has no lag and is super responsive. I also drove it in the Colorado mountains and there is no need for a V8 unless your towing. Of course the V8 would feel great too.

Re: Hemi vs. V6 driveability

This posts makes me wonder if Jeep updated the throttle response maps in the '17's because I will be in the market for one soon. I drove a '14 Summit Hemi and the next day drove a '17 Laredo V6 expecting it to be underpowered. I was surprised at how quick the V6 was and left me thinking that the V8 was not at all needed unless I just had to have one. I got the V6 right up to speed and its power delivery was smoother and with less chassis vibration than the Hemi. Its idle was smoother and at 75mph, it was quieter than the V8.

Don't get me wrong, I like the power of the Hemi but the $10k difference to step up to a Limited or above and adding the Hemi did not seem like a worth wile expense along with sacrificing 5+ mpg's. I reset both mileage computers, drove the same basic route, and the Hemi read about 16 where the V6 was 22.

Re: Hemi vs. V6 driveability

I drive with eco turned off (button pushed and lite on) all the time. This really improves the pr range and smooth 8 speed shifting. I also turn off the engine stop feature. That one has to be pushed every time on startup. Also I turn off the lane departure option. I find that annoying. So my 3 middle buttons are always lit meaning they are turned off. The sport mode button lit means it's turned on and this is uncomfortable to me so never used.

Re: Hemi vs. V6 driveability

Comparing 2 vehicles respective performance in flat out contests of speed has little do due with "drive-ability" power delivery.
So, commenting that a newer V6 engine is just as fast as an older V8 engine does not put in perspective the lower rpm behavior of the 2 engines in daily driving.
The best example I have of just such is, I once had a '78 Pontiac Wagon with a 350-4bbl that had been warmed over for towing a travel trailer. It was essentially a truck motor. I bought a Beretta GT (please, I don't want to hear it) and that car was actually faster when both were pinned to the floor, but, driving around town and entering merge ramps it sure did not feel it. It needed to be prodded and run harder to do what the old V8 simply got done as another routine task.

My wife test drove both an Overland V6-8spd and an Overland V8-8spd. She wanted nothing to do with the V6... and she was not acting like Burt Reynolds on the test drives.

The V6 will be a little more spirited to "daily drive", the V8, more lackadaisical.

Oh, I love the 3.6-6spd manual in my Wrangler, so this is not a I hate V6's post.

This is spot on. Yes, the V6 moves the truck when you want it to move, but you have to push it very hard.

The lack of torque is more obvious than the lack of horsepower. When I take a low speed turn and the transmission has me in 3rd, whether not eco is on, is pretty annoying. It feels like it's going to die until I make it downshift to 2nd. A little more torque or a better (smarter) transmission would make this more tolerable.

THAT is what driveability is all about...not how fast you get to 60. Staying in one gear on the highway makes for a nice driving experience, not constantly bouncing around between 6th, 7th, and 8th.

My post was not about hating on the V6 either. I PERSONALLY don't like it, and it's no longer a fit for ME, or MY driving style.

In all likelihood, the diesel is probably the best fit. I like my power down low. I really need to spend time with the V8 and the diesel before making the switch.

Hopefully we can order a diesel again soon...they're pretty damn hard to find used.

Well I didn't want to dilute the thread with bringing up diesel, but see post #11 early on.... !
