Help me decide. Diesel or HEMI

I have done countless hours of research, and just when I think I have made my decision, I find something to sway me.

I am coming from a 2011 JGC Overland with HEMI and loved it. I will say the transmission left something to be desired, but from what I have read, the new 8-speed is a dream (with HEMI or Diesel).

I am not really basing my decision on economy, but it doesn't hurt.

I am also not really basing my decision on upfront cost, but again, it doesn't hurt.

What I am mostly interested in, is day-to-day experience. The HEMI had plenty of power and never left me disappointed. How does the Diesel stack up? I have read "Hemi for passing, Diesel for towing".

I have never owned a diesel powered vehicle, but know that they can be tuned for some serious power. My buddy had a Ram 2500 Cummins, and with a little tuning, was putting out some impressive numbers. I have not seen anything concrete for the ECO Diesel though.

I do not plan to do much towing, and if I do, it would be light duty and not often.

Am I missing anything? Please let me know your thoughts. I am looking to buy within a week.

Thanks in advance!

Re: Help me decide. Diesel or HEMI

I think you've already answered the question based on your experience with the Hemi.

Stick with it.

Re: Help me decide. Diesel or HEMI

What is your normal daily drive? That is distance and style.
If it i short start/stop then ignore the CRD, if it is a longer smoother run, then consider it.

A couple of the CRD tuning threads - Tuning your EcoDiesel

Anyone tuned a CRD yet?

Love my CRD.

Have you actually driven a CRD yet? Sounds like you haven't. You also need to drive a hemi with the new 8sp to see that a difference that has made.

Re: Help me decide. Diesel or HEMI

For me, I wanted the Hemi power, but couldn't stomach the MPGs, so I went diesel. Next best thing. Feels quick, but is not as quick as either of the other two engines in a drag race, but effortless hill climbing compared to the gasser 6. Tuning? Maybe, the Bluespark is good, and better options are coming.

Honestly, if you I didn't care about MPGs, I'd get the Hemi. I didn't even bother test driving the Hemi. I knew I'd like it too much.

Snuke's right though, you really need to try them both before finalizing where to out your $50K.

Love my CRD.
My commute to work is about 15 one way. On the weekend however, I might be inclined to take a 100 mile camping trip.

Mostly though,, it will be a daily driver.

Re: Help me decide. Diesel or HEMI

Doesn't the Diesel cost about double to buy vs HEMI? The flip side the resell value will be there with the Diesel vs the HEMI.

Aren't Diesel's a bit or quite a bit more to maintain? I know in the heavy duty trucks there is a lot more cost to maintaining them, not sure on these EcoDiesels.

I would think you would have to do a lot of driving to make it worth while. I also heard that they are a bit "flat" in the 40 to 70mph range...

I also thought about a new limited diesel before i ended up with my 2011 Summit with the HEMI. I was 55/45 HEMI vs Diesel, so much to love with each...

Maybe a HEMI EcoDiesel is in the future...lol

Re: Help me decide. Diesel or HEMI

i have been debating this for a while now. really tried to talk myself into a diesel but just could not justify it.

the VM 3.0 is a fantastic engine, no one can deny that. but the emissions stuff that Jeep has to put on to meet requirements by epa are expensive and crippling for the engine. price difference is minimal between engines, so you will be saving money on gas. the problem is that when the mechanical parts wear out in the turbocharger, cat, DPF, they will be super expensive. this is not a huge deal if you have the unlimited warranty. however, you cant just go down to your local parts store and pick up the parts in stock. not to mention the $150 oil changes.

bottom line (in my opinion), if you drive long distances, add lots of miles on the jeep each year, and plan to get rid of it in 3-4 years, then the diesel is perfect.

anything else (performance upgrades, city commuter, low annual mileage) is better suited for hemi.

I have not done this yet. I will test drive the diesel this weekend though. I think THIS might be all I need to decide.

I have driven the new HEMI w/8-speed. Loved it.

Please keep the responses coming though. Why should I choose one over the other?

Re: Help me decide. Diesel or HEMI

I would suggest driving all three engine choices. The '14 V6 is as fast or faster than the '11 to '13 Hemi because of the transmission. It is significantly less expensive than the Hemi or Diesel, feels a bit lighter and gets decent gas mileage for the weight of these vehicles. There are currently incentives on the Diesels, so that might lessen the sting of that big upcharge.

Personally, we went with the Hemi. We tried the V6 as well, and probably would have been fine with it, but after trying the Hemi it came home with us. I was HOPING to get close to 17MPG (what we averaged with our old GMC Jimmy), and we average a bit over 18mpg with some tanks being almost 20, which was a pleasant surprise. My guess is the V6 would have done 2-3 MPG better, which is significant, but we don't put on that many miles so it wasn't a big issue for us. I did notice that as the engine broke in the mileage went up noticeably. I was a bit surprised at how much of a difference (improvement) there was all around as it got broken in, in many respects. Now it seems even quicker, shifts smoother, etc.

From a service prospective, I have experience with diesels (GM and VW) and while the mileage is great and they are usually reliable, when things do go wrong it gets REALLY expensive, so from an economy perspective it never worked out for me. On top of that a lot of places don't have much experience with them so even minor issues can be a problem. The VM Motori Diesel is a bit too new here in the US and there seems to be some teething pains, both with some of the systems (like the DEF injection) as well as service department knowledge and parts availability issues. I am sure that stuff will improve, but experience has made me shy away for now. Last I heard Jeep was NOT offering the Lifetime Maxcare bumper to bumper warranty on the Diesel. (Hmm...) I haven't seen an issue here with the WK2 Hemis, and every MOPAR shop out there knows how to work on them. The transmission on the Hemi (and Diesel) seems to be rock solid as well.

So, all in all I am happy so far with our '14 Overland Hemi and look forward to many years of ownership. Do yourself a favor and try them all.

Yes they cost more to service. The dealer should be able to provide the schedule service costs for both to compare.

Depends on what you consider worthwhile. If you're considering the CRD from a purely economic choice, then it's a relatively easy calculation, once you have average fuel and service costs.
We didn't it look at it from an economics standpoint. We tow horses, so it was a no brainer over the 3.6 and V8. However it also has quite the different driving experience and we both preferred it over the 3.6. We never considered the Hemi. The mountain of torque is very addictive.

As for "flat" spot, no, not even close. It is still well within it's peak torque at that speed. It accelerates in that range as easy as it does from a stand still. You build speed so easily you don't even realise it because the engine doesn't rev up like a petrol.
There is a slight learning curve as to how to apply the throttle to negate turbo lag. I no longer bother turning off the ECO mode or putting it into Sport mode as I know how to get it going quickly without any surging.

Wait. Which engine are you talking about again? When was the last time you had ANY engine related failure and came away thinking "hmmm, THAT was cheap"?

Honestly, the above argument is more bias than true isn't it? All engines are expensive if they fail, BUT modern engines hardly ever fail and I'm guessing diesels in general are even more reliable than gassers. Am I wrong? I hear this argument a lot, but have yet to see any evidence that shows Diesel engines are more expensive to repair WHEN FAILURE RATE is taken into account.
