Re: 2015 Grand Cherokee - V-8 Or V-6 ??

Even when I ran the Stock Wheels all winter (18" ) I only got 17MPH average'


YES...with the heavier tires and 22's I was getting like 15MPG and with these 20"s I'm running now I'm getting 16MPG...

I HAVE NEVER seen 30MPG on my V6 and I have 26K miles now...HOW the F do you get 30MPG ????

My foot isn't that heavy

Re: 2015 Grand Cherokee - V-8 Or V-6 ??

There's just NO way you're getting 30MPG...that's probably coasting down hill for like 30 seconds you get that...let's see the average based over a LONG distance...

13-14

or 16-18MPG...what's the real difference ???it's just not that much savings unless you do a million miles a year...Can you tell I hate the V6?

I wish I bought the V8 for sure

this is what I just snapped from my Jeep ..

Re: 2015 Grand Cherokee - V-8 Or V-6 ??

Have you reset the thing^^^?

I just pumped 89 as i always do. This morning on my commute to work mostly highway avg 21mpg. Since i just fueled went down to 18mpg(371mi to empty). Granted i even went to a drive thru and came down to 16.4.

I'd hate to see how much you were to drop down in a drive thru...

Re: 2015 Grand Cherokee - V-8 Or V-6 ??

I'm not going by JUST what the Gauges say as that is relative to what the car is getting at that moment...I'm actually giving you my Average based on what I put in the tank and mileage traveled...the good ole fashioned way we used to do things before these fancy computers..

I challenge anyone out there to actually track mileage and fuel consumed at the pump and not pay attention to what the gauge says at that moment...I'm guessing you'll see numbers similar to mine

I loved the hemi I but don't miss the hemi. The v6 w/ 8 speed trans gives me good acceleration when passing on the highway. I do like getting 5 more mpg, even though gas is cheap now. My bigger regret about getting the 2011 was that it wasn't 4wd. I have that now on the 2015. Given the choice I would choose it over the hemi.

Just my opinion...

Unfortunately, you are basing the argument on a fallacy of comparing an old implementation without the newest transmission and engine controls with a different engine--better transmission, and newer engine controls. They really aren't comparable as the new transmission in current hemi's moots a lot of problems with older ones.

I'd drive my 2014 hemi off a cliff if I only got 16 mpg...

However, if you desire power and fuel economy, I highly recommend the diesel. The lowest trim level it's offered in is the Limited, should run in the mid to high 30s in 4x2 if you don't go too heavy on the options. You'll have nearly the same towing capacity as the HEMI, it will fly when you want it to and you'll get 500-600 miles on a tank. But if you think the HEMI is rare, the diesel is even more so. You'll probably have to order it but I would also try carmax.com. The one in Georgia sells new Jeeps and they will ship it to the store nearest your home for a small fee.

I'll take issue with this, with some qualifications based on your local driving conditions and your steady state driving skills.

The recommended hemi fuel is more expensive, since it is midgrade.
The differences in mileage would be if you must slog in town traffic where you have to regularly hit the gas, the hemi will indeed pay a penalty.

However, if you drive at speed on vertically varying terrain, I'll challenge your V6 any day.

Seems the Pentastar isn't doing so bad.
Somewhat missing in the definition of what constitutes "best" ... although I'd tend to agree with the choice of the hellcat engine.

Quite interesting but relevant only if your driving conditions and style match those of the test. Plus, it helps to multiple the Imperial MPG by .83 to get closer to USA.
From that, I have to challenge their numbers, since as 25mpg I is 20.75 mpg USA, and you can easily exceed that on cross country trips without headwinds, strong climbs, and even in places with 85 mph speed limits, where the hemi starts to gain nicely on the other 2 engines. It won't beat them, but it is far less affected by speed and the need to climb or face headwinds.

If mpg is really your criteria, you honestly have no business buying a GC in the first place. There are many other crossovers with a heck of a lot better mileage and similar or better cargo capacities available.

Re: 2015 Grand Cherokee - V-8 Or V-6 ??

It goes without saying that Canadian weather is vastly different from Arizona's, so I understand your preference for a RWD truck.

As for engines, I can't give any recommendations since I'm still hemming and hawing. In my scenario, I am leaning towards the Pentastar. I would prefer the diesel for the fuel cost savings, however since I am leasing the vehicle for only 3 years, I won't own the vehicle long enough to recoup the price premium of $5,000. There is a promotion on now where the diesel engine is a no cost option.

If I were to opt for the Hemi, I get slapped with a $2,000 gas guzzler sales tax in addition to a Large-Cylinder Capacity Engine tax on my vehicle registration of $164 annually.

Coming back to the Pentastar, well it comes with a $2,150 discount off the MSRP of the Jeep.

Since I am not off-roading, will I truly need the other engines? I doubt it. What I am missing out on is Quadra-Drive since the V6 Overland comes with Quadra-Trac II. It is a concern for my winter driving, but if I could handle winter in a RWD BMW 7er luxobarge with proper winter tires, I think I'll be fine.

If I were to keep the vehicle for a couple decades like yourself, the diesel would be my choice without a doubt since the savings would be huge over the lifetime of the vehicle. On the other hand, the Hemi is a proven and mature engine that should prove reliable as well in your use.

30 is definitely up there but I don't doubt he could probably see that in ideal conditions. lofty numbers like that are highway cruising only numbers, hit the cruise control on fairly flat highway, vehicle not load and cruise low speeds like the 60 he was doing and you would be surprised what you can get out of them but as soon as you get into any type of traffic or stopping your numbers will not stay like that and head down quick. the same applies to the v8 put it in the same situation as he was doing and you may approach around 27. I posted pics a while ago on here of a highway only trip and I had cruise set at 65 and it gave me 25.8 mpg drop it down to the 60 he was doing and maybe squeeze another 1 mpg out of it with the reduced speed maybe approach around 27 would probably not be unreasonable. But remember those are ideal conditions and the only way the hemi can approach those is the MDS stays on a good deal of the time in those lower speeds so you are only using 4 of the 8 cylinders for a large portion of the trip, keep cruise control on also. I don't really see much beyond 24-25 highway because to get numbers much beyond that you would have to be going kinda slow on the highway 60 or 55 or something and most major highway speeds now are at least 65.
Kinda cool to be able to see numbers like that but I really didn't buy the jeep and v8 to worry much about mileage its doing a lot better on mileage generally than I was expecting for a v8 but even if it wasn't I would not care because that's not why I bought this type of car and engine.
