Hemi or diesel based on this criteria (Canada)....

Hi all, I'm looking at ordering a 2015 Overland but trying to decide on the diesel or hemi. I've driven both and like how they drive. Based on this criteria, which one do you think would make sense (keep in mind in Ontario they seem to have the no charge diesel or hemi sometimes so would order one when the right promo is on).

1. Drive about 15000kms/9000mi per year total
2. 85% city driving 5 to 15km short trips
3. Would occasionally tow up to 1700lbs on 50km to 100km trips. About 5 times a year i would do 600km tow trips.
4. 89 octane gas and diesel fuel are closely priced in Ontario so not much concern there.
5. Would get the 7yr warranty on either.

Based on that is the diesel also a good option? I've read that short trips aren't ideal for them? If so then why? Never had a diesel but from my research the maintenance costs won't be bad based on the amt I'll drive. The mpg and low rpm torque in the city makes me really want to consider it.

I would appreciate your feedback.

Thanks

Re: Hemi or diesel based on this criteria (Canada)....

You don’t tow much, or a heavy amount so it is effectively irrelevant, the 3.6lt would be fine.
Based on your 85% short trip driving, I would give the CRD a pass. I love ours, but it is very suited to our driving requirements.
We do about 18,000km per year, the daily trip of 40km each way with an average of 60km/h (including time spent stopped at lights etc..), so a good deal of 80km/h. We also tow two horses. For us it was a no brainer decision for the CRD.
For you, best to stick to petrol, too much short trip use and not enough high speed or high strain use to get the DPF to function correctly.

Re: Hemi or diesel based on this criteria (Canada)....

I agree with ^^^ post above. Your debate should be between the V6 and V8, not the Diesel and the V8. From a purely cost perspective, V6 would work for your needs.

Are you saying you can get the upgrade form the V6 standard to either V8 to Diesel at no charge?

Also, how long do you plan on keeping the GC....7 years?

Re: Hemi or diesel based on this criteria (Canada)....

Thanks for the replies. I did try the v6 but liked the power of how both the diesel or hemi drove much better. To me its between the diesel and hemi at this point.

Right now for example there is no charge diesel offer in Ontario on 2014's. So it's same price as the v6 this month.

Based on the short trips it sounds like i could have trouble with the diesel if I'm almost always driving aroind town??

I plan to buy brand new so would hope to keep it at least 7 years.

The price of fuel on the hemi on city driving makes me think diesel here, but if I'm running the risk of motor issues with short driving the diesel than i will go hemi.

Another thing to add - i saw there was a pcm update for the diesel that fixed a bunch of shift isssues. Did the hemi have the same problem and did it also get an update?

Thanks

Re: Hemi or diesel based on this criteria (Canada)....

I do a lot if short trips (office is 2 miles from home) then mix in a lot if longer trips and towing. I picked my CRD up on November 9, 2013 so in coming up on 1 year and just over 17k miles.

I go for weeks driving in town though, then take longer trips, and go back to weeks in town.

During short trip driving I've been prompted to keep driving to let the DPF regenerate twice. So it does happen and then it's suggested to cruise around for 10min.

I've loved mine - And since most of the time the CRD costs more then the gas Hemi to buy - I'd take the free upgrade fit resale alone.

This is where I'd be at. Mostly weeks in city, once in a while drive out of town for a cruise or to visit a local town / local fishing (boat in tow) and a few times a year do 400 mile trips usually towing as well.

I'll have to read more on this dpf regeneration process. What about mpgs on the diesel if it isn't getting that warm? I'm not far from Detroit so the weather doesn't get too cold compared to up north.

Thanks again.

Re: Hemi or diesel based on this criteria (Canada)....

For me that choice is a no braner: get the diesel, it is much more efficient and modern than the hemi. On any WK2 I'd get the long term service contract, the electronics can get expensive quickly.

OTOH my '12 Pentastar does everything I want including towing & in Florida there is about a 20% premium for diesel over 87 PON.

Re: Hemi or diesel based on this criteria (Canada)....

I can see where a free diesel engine is tempting just make sure it is the diesel engine you want and not the free deal that is influencing. With that said, I don't think you can go "wrong" with the diesel or really any of the three options as they would all fit your requirements. Just a personal preference thing.

No problems with the V8....I have one in my 2014, had one in my 2011, had one in my 2005, had one in my one before that and the one before that too.

Re: Hemi or diesel based on this criteria (Canada)....

If i can get the diesel for same or less than the hemi I'll strongly consider it.

However what is the dpf regenerate issue with the short trips most of the time?

What other issues could i run into if not getting the diesel warm or on long trips?

I like the power of either but clearly diesel will get much better city mpg and resale.

Thanks

Re: Hemi or diesel based on this criteria (Canada)....

The diesel particulate filter (DPF) traps particles flowing out of the diesel exhaust stream.

There are sensors built into the exhaust system to determine how blocked the particulate filter is. When it reaches a certain level the ECM starts a regen process that heats the DFP up to 1100-1200 degrees to burn off the particles.

This burn off needs 1500+ rpms for roughly 15 minutes to complete. Short trips do not give you enough time or consistent rpms to complete a regen.

If the build up can't be burned off the computer will display a warning to you to drive at highway speeds until the regen is complete. If you ignore it my understanding is that the vehicle will go into a limp home mode.

My commute is mostly freeway and just about the right length to complete a regen. I also do a fair amount of road trips. The diesel is a good fit for my driving patterns and my lifetime fuel economy is 28mpg (80% hiway).

If I were in your situation I would visit the diesel subforum and read up on the issue.

Re: Hemi or diesel based on this criteria (Canada)....

I will read into dpf issues thanks. Based on fuel alone i would save $1000 a year over the hemi v8 which makes me consoder the diesel. Also like the low end torque for city and towing. The v8 would be great too its just the fuel cost in city.

I have no issues taking it on a hwy run once in a while to run the regen; however the comment about cold driving and short trips - what is the concern there? Is thete any difference in cabin heating in winter with the diesel?

Thanks again
