The 5.7 is also a pretty cheap option I know it's increased some but when I bought my 2014 it was $2699 option after discounting it was like a $2300 option when considering a 55k vehicle that's pretty minimal to move from a v6 to a v8 engine combine that with cheap gas and not much of a decision in my book. But I get some people could careless about power and engines so why spend an extra dime on an engine just stay with the base. For people that do care the v8/8spd is a great combo.

For those who drive a Hemi 5.7

My previous 14 JGC was a V6 and what I hated was the weak sound from engine and exhaust.

The main reason why I went the V8 route is for the great engine sound and for the added performance

MPG is not a deal breaker for me, I expected low numbers and was pleasantly surprise to average 12-13 combined. Mostly city driving (70%)

Re: For those who drive a Hemi 5.7

Sorry I have to disagree with that to some extent , I traded in 2 V6s one was a 2013 Laredo and a 2014 Overland both had a lower trade in value than a used V8s and also if the V8 and diesel were offered on lower trims they would probably sell more of them ,in the end it does come down to personal opinion but owning both engine types the gas mileage on the V6 compared to the V8 isn't a big difference thats why it made sense to me to trade it in and have the extra power when needed

Yah I mean it is what it is. There are other factors that play into trade in values as well so it's hard to say exactly, but I do know for a fact the V6 models don't sit on the lots as long.
As far as fuel economy differences, I get 100 more miles per tank than I did with my V8. So I'm definitely happy with that. Since I don't offroad, don't tow, don't even ever have anyone else in my Jeep, I could probably get away with a 4banger in my Jeep just fine lol.

Yuck, I don't even want to think about a 4 banger in the Jeep haha. I know the dealers around here don't order a whole lot of V8's at all for dealer stock. You might see a few, depending on location, but that's about it. I'd say 99% of dealer stock has the V6.

That being said - I liked the V6's, but it's going to be rough going back to one. The wife is up for a new car and everything she's looking at has a 4cyl...eesh!

This is all very true. The current purchase price of $3,200.00+ for the HEMI V-8, buys a lot more than just 2 more holes in the block.

Re: For those who drive a Hemi 5.7

Demographics can play a large part as to what is available here most
Of the models are Laredo's and Eco Diesels, but for the price of the Eco Diesel you might as well go for the SRT,and I agree there are all sorts of things that go into pricing but the hemi engine alone gets you a higher price , both models I owned were had all the gadgets that people like, take a look at black book .com for car values and you will see V6s are valued lower regardless of Trim

Yeah you know, what's another 20 grand right? Lol big difference in price between any model diesel and an SRT. Not to mention over double the mpg.

Re: For those who drive a Hemi 5.7

I know in the Ram truck line, many of the Eco Diesel models are as cheap, or even cheaper than the 5.7 HEMI V-8 models. I think the reason is because they're not selling all that well. People who want a diesel in a full size truck are spending the extra money and buying the Cummins 6.7 Turbo Diesel.... Not the little Fiat.

Re: For those who drive a Hemi 5.7

^^I think the Ram is like the oldest of the bunch.. All have been redesigned since so they have to discount them more to sell. Or that's what I think anyways. Still nice trucks though

Both 8spd transmissions are ZF. Both are what you would find in Mercedes, Audi, Bentley etc. it's just that they have some different internals and some externals for a different torque rating. The higher torque rating internals are less efficient. That's why it doesn't make sense to use the higher torque internals on a V6. Yes that probably makes it cost more, but it's not anything significantly better. Just better suited to a V8. The problem with the ZF transmission is that Mercedes did not decide to share its tuning abilities with it with Chrysler. They designed for it to be used by them, but didn't share all of the secrets. That's why there have been so many transmission service updates.

Re: For those who drive a Hemi 5.7

The biggest difference with the v6 and v8 transmissions is that the v6 trans is assembled by Chrysler in the states. The v8 trans is assembled by zf at their facility. This was done to save cost on the v6 trans because jeep sells so many more v6 cars than v8. This is what has lead to some of the v6 trans quality issues (valve body). The above poster is correct about the trans strategy and programming. MB did not provide that info so jeep had to develop that themselves. That lead to the other poor driveability issues.

Honestly...the zf trans is actually quite good. It does some funky things once in a while. But the overall driving experience is good.

The v8 engine has been excellent for me so far. I'm averaging around 17-18 mpg on my casual work commute on back country roads. About 21 on the highway at 75mph. And about 15 in bad city driving. Not terrible at all. The torque of this motor is impressive.
