2014 Jeep Grand Cherokee Diesel Takes on the Extreme Ike Gantlet Towing Test
Вставка
- Опубліковано 9 тра 2014
- ( www.TFLcar.com ) The 2014 Jeep Grand Cherokee Diesel is perhaps the best towing Jeep you can buy. The 3.0L ECODiesel is a torque monster that should be great for towing. In a brand new Ike Gauntlet Max extreme towing test review, we see just how well it handles America's highest and steepest highway towing over 5,700 pounds up the Ike Gauntlet.
The Ike Gauntlet Max is a timed run up one of America's steepest highways from 9,000 feet above sea level to the top of the mountain at entrance to the Eisenhower Tunnel in Colorado.

As a Grand Cherokee driver I would have turned off the ECO button because that works with the shift map.
The altitude seems to be the largest impact. I have a 7000 Pound trailer I tow with the Summit EcoDiesel and it has no issues with any of the climbs at 7% in the Virginias. I also have a weight distribution and sway control system though so I don't get that same push around feel they spoke of.
I think the real test you need to do is do a side by side with the Hemi and Ecodiesel showing regular mpg and towing mpg. That would be really telling to those who are trying to do the breakeven for the $2k extra that the diesel costs over the Hemi. I've got an Ecodiesel and get 30+ mpg on the highway and my last big tow was an enclosed 6k lb trailer through the mountains in Pennsylvania and got 16.4 mpg and I was going 70+ mph the whole way (but found that using sport mode with Eco off, and then driving faster and using the shift to keep the RPM right around 2k where it's really happy so I was able to pull up most hills in 7th gear which also down transmission temps. There's a trick to do this.
I have a 2017 Cherokee Overland with the 5.7. Towed a 20x8 enclosed trailer when we moved 400 miles. Empty trailer weight is 3400 lbs, I'm guessing it was 5500 lbs loaded. Jeeped with the 5.7, 8 speed trans, and air suspension towed it like a champ! Was super impressed. The only issue was trailer wag at times but a short wheel base vehicle compared to a truck wasn't unexpected.
I could almost guarantee that Hemi will do a better job than the EcoD... at least at highspeeds.
Could you lower the music levels, please? I have the volume set to where I can hear you comfortably but I have to keep turning it down during the music settings because its too loud.
I AGREE!!!
It makes me happy seeing Emmy on here. She is seriously a great addition to the team. Insightful and enthusiastic. Favorite channel on UA-cam for sure.
Enjoyed the video! Thanks for posting guys!
Great show, guys - nice to see Emme! (Roman and Nathan, too) :)
And, congrats on getting a start on the Tatra story!
I get the impression that people often confuse the power curves of diesels and gas engines. They operate completely differently. Gas engines make significantly more HP as the RPMs go up until you hit the peak HP speed. This is because the rev's are increasing faster than the torque is dropping. So downshifting when the engine is loaded down in a gas engine will give you more revs, and thus HP to pull.
Diesel's are a completely different animal. Diesels are pulling as hard as they are going to pull down around 2000-2750 RPM (in the case of the Jeep). The peak HP is only up at around 4000 RPM, but in fact it's making almost the same HP from 3000 to 4000 RPM - this means that the torque is dropping at almost the same rate as the RPM are increasing. Past 4000 RPM both the HP and the torque are dropping. So if the transmission is shifted down at 2750 RPM, you'll barely gain any HP, but you'll lose a lot of torque.
Diesels are intended to be slow rev'ing engines, but will pull hard almost from the get-go, like when leaving a stop light. Gas engines are fast spinning engines that need to get on-cam before they can do much work. The big benefit for diesels is pulling at low rev's, and the fuel costs as long as you don't exceed their limits. That's why the overwhelming majority of long-haul trucks are diesels. In this area the Jeep diesel did shine.
Much better music! Surprised there is no tow haul mode, since my 2011 Hemi has that feature. Come to think of it, would love to see you folks do the test on the same rig with Hemi power. Keep up the great work
I'm really finding it hard to find another SUV in it's class that has all these high end quality products and performance for this price!
Then buy the Jeep
I really like the Ike Gantlet testing. I live in Denver and it's great to see testing up in the mtns. Nothing like being under powered in the mtns.
Awesome intro and video
I really wish you guys would revisit this with the 2018. Diesel grand Cherokee and such. except, use a normal trailer like you do for TFLTRUCK :-)
5 years laters, the jeep gladiator is 1 minute slower. GC FTW
would be possible to do the same towing test between Jeep, Touareg, Bmw X5 ??? Thank you
Could we see the same test with the 3.0CRD WK to compare like for like and again compare it to the HEMI's please? Great channel guys.
This thing should have pulled that boat up the hill no problem. Obviously the biggest hindrance was its transmission programming. That eighth gear is very high (0.67:1). None of the other vehicles that have attempted this have stayed in the highest gear for most of the way up (sport mode would have offered a much different result). The oil temp started to climb because of poor circulation. I'm no jeep enthusiast but I do recognize the benefits of small diesels in light trucks/SUVs.
I've seen a lot of comments saying the GC is much lighter than the Ram 1500. It is slightly lighter 5400 vs 6000. The gear ratios offered in the Ram truck are reflective of that and it should have similar performance to the GC.
Don't let this video jade your view of small diesel performance or unibody design SUVs. I drive a Touareg TDi and would be hard pressed to find a better tow vehicle.
For an update, I bought my GC EcoDiesel in 2015 and have had many trips to the Ouachita mountains with my Sanger ski boat in tow weighing in at 4500 pounds. If you shift it with the paddles and keep it from lugging like most diesel owners know hot to, the hottest I have seen it get is 220F in the middle of the summer and the trans temps never go over 200F. The towing is still great and it out tows my 2004 hemi by leaps. Satisfied completely with it. The DeF system is another story.
How's reliability?
@@mkay6115 with the AEM v1 update it sucked. Never had any major issues till I let them update the ecu. Held out about 6 months and couldn’t deal with all the crap it was causing. All emission related issues. Was in the shop almost a month and a half and ended up having to get a whole new intake manifold. Purchased a tune shortly after to turn off the EGR and other stuff.
@@kevinkanak1380 Kevin, what tune did you run? Where are you located? I'm in Commiefornia and diesels require smog certifications bi-anually, so I can't have anything modified or deleted. Would need a tuner with a stock setting. Thanks.
If it has paddle shifters, they showed engaged manual shifting and kept the rpms in the proper power band. Plus they probably left it in eco mode.
Now that is a conclusive test. Nice to see what those numbers translate in the real world. Maybe just a suggestion; it would be nice to see a run doing manual shifting if it does any better. I'm sure you could exploit more power but would that cause other issues (heat)? Anyway, nice video.
One thing I will say is that it isn't because the Jeep has a unibody vs an actual frame that you feel a difference between a pick up and the Jeep... its the length of the wheelbase. The longer the truck the better it will tow. Jeep wrangler (older ones) were power wise fine for 4-5k pounds but the wheelbase was so short that it made it hard to control while stoping quickly.
+The Fast Lane Car. Surge breaks aren't really a fair representation of a vehicles ability to control a trailer while braking. once you're reaching a vehicles limit you should really be using electronic brakes.
Everyone on this channel is well spoken they don't waste my time
You would think you guys could figure out that sport mode would be tow/ haul mode in the jeep. They do the same thing however for whatever reason jeep decided to market it differently.
it would have been nice to see a continuous cluster view in one of the corners of the screen to watch the levels and mpg. I heard it but its still nice to see.
How much does the regular, gas engine v6 tow? How does the srt8 do off road? Great channel. Thank you.
This jeep shared a chassis with the mbz ml. Also as someone who owns the six grand Cherokee and toes with it I expected much better from the diesel the v6 towes very good.
You guys need to test the Hemi Grand Cherokee for towing...Will out pull this baby diesel any day!
can you guys do a 2017 or 2018 towing for jeep grand cherokee
thanks
Damnit I love Silverthorne, CO.
Emmy raised an interesting point about payload. In this case the luggage could go in the boat. The extra people might complain about having to travel in the boat though :)
How come you guys haven't done this test with the Ram 1500 Ecodiesel? I'm curious how it would fare.
2:21 Colorado - TOP OF THE WORLD (ROFL) I often tell my USA friends including ex school teachers that the geography classes in USA must really teach that the world finishes 12 miles off the USA coast, otherwise they would invite countries like Australia to participate in the World Series. ( But they are afraid we will beat them again like with the Americas Cup in Rhode Island). FYI The Top of the World is in the Himalayas ( Mt Everest to be exact at 29002 ft ASL) I have a 2006 5sp Jeep Grand Cherokee Navigator 3 Lt diesel with a Merc Engine and drive-train. It is good so far. Am interested in its towing capacity etc.
At 18:28 Your Czech car reminds me of a 1950's Nash Rambler
can you please do the same with the hemi powered version?
Emmi is very cool. Great personality.
It would be interesting to see TFL do the exact same test with the 2014 (or 2015) GC SRT. It has a 8 speed automatic, tow mode and 7200lbs towing capacity and all, but how much will it be gasping for air at that altitude?
sure would be nice to see the same test done with hemi... same boat, same hill. It would be interesting to see the difference between the 2 motors with the same towing capacity.
It would probably do alright in Kentucky! Our little mountains ain't as big as the Rockies!
Now you need to do a Ike Gauntlet Maximum test with the Jeep Cherokee 3.2L V6. 4500lbs of towing capacity.
Emmy is great reviewer.
Nathan would the eco diesel be adequate in the Ram truck? looks like it couldnt even compare to the pentastar.
This video is an excellent demonstration of how torque is the most misrepresented term in automotive marketing. This engine has more torque than the Tundra 5.7, the Ram Hemi 5.7 or the Titan 5.6 for just a few examples. This engine is completely pulverized by those same engines in much heavier setup. Don't get me wrong. The Dodge ecodiesel is a fantastically economical engine. It just doesn't have the same power curve. Don't get fooled by the torque marketing. They just love to take your money.
Not bad at all for a mid-size SUV. And it looks gorgeous inside and out. Obviously it's not meant to tow very heavy loads, it's not a pickup truck. But still very impressive. Jeep did a good job with this one.
Please test it whith the HEMI and the towing group if possible :)
Nice review guys :D
Hemi is worse for this case. I have both the diesel and Hemi, and have towed the same trailer with both. The diesel is better, except going downhill. Diesel has less engine braking than the gasser.
What I was very disappointed to not have pointed out, and I think it is very important, is that the GC does not hold back the load going downhill. I downshift into 3rd at the top of the tunnel when towing my 3,500 lb camper. The programming upshifts on its own, so I don't have my speed restrained. I have to use my brakes often, even when I keep slowing down and downshifting. To me, this is a major issue with the diesel. As they showed in the video, the brakes got hot with all the braking they had to do. Jeep needs to address this!
Also, if they didn't use Sport mode when going up the hill, that's their bad choice. Don't bad-mouth the shifting when you are using it in Eco mode. I could not tell, though, if they said they had it in Eco mode, or "normal" mode. Even normal mode, though, is not what you should be climbing to the tunnel with. Use the tools available, instead of complaining that a hammer won't cut the board efficiently.
I would love to see this test with the Audi Q7 V12 TDI
I think it did pretty well. This would be a good vehicle for me if it wasn't over 50 grand! I have one son, a large dog and a boat. For occasional towing I think it would do fine, particularly as there are not many hills around here.
Does the rear have self leveling when trailer is hooked up?
I'm really hoping for a 2015 Ram 1500 Ecodiesel Ike Gauntlet. Is that going to happen???
I think it's easy to forget that the max tow is over 3 tons watching this video!!! That's crazy for what's basically an SUV crossover! My guess is that most vehicles that do the ice gauntlet max will not have this much payload.
I'd like to see a 5.7 Hemi run. Sure the EcoD has 30 more ft lbs of max torque but it lacks a whopping 120 hp that the Hemi has. I think the 5.7 would out perform in your gantlet.
If you had set the cruise to 55mph would the computer have downshifted to maintain that? What would you think of towing a 3,000 travel trailer?
They were wrong. It's got nothing to do with the frame of a truck. If anything the frame will flex and cause stability problems, whereas the unibody will not, it is stiff. The real issue is the wheelbase and the rear overhang of the Jeep. You may want a sway control and load distribution mechanisms adding. That should help quite a bit.
Can you retry it with a 2018 Jeep Grand Cherokee with 5.7 l V8 with a box trailer with full trailer brakes
Will that diesel run on biodiesel? Why not manually down shift?
Thank you guys for a real test. Know can you try to do a test between the Jeep and the Touareg diesel.
I am not interested in which one has more leather or goes better off road. I will never see more then a gravel road. I need something that will give me a good mileage and as reliable is possible with a 3500 lbs camper behind across then country
Thank you so much
3500 is not all that so you should be going going by manufacturer specs
+Bimmer Rider Get a Touareg. I have had one since 2013 (TDI) and it is flawless on the highway at 65 mph towing a 3500 R-Pod 177 Trailer. 15 mpg towing. Visit a Jeep forum and see what owners of the GC diesel have to say about reliability and finish on their vehicles.

I'd like to see a Mercedes AMG model towing with over 500HP. Even a older G55, in fact that would be my favourite.
I have this exact vehicle. Towing over 3500 lbs requires a weight distribution hitch. If they follow the manufacturer's recommendations as stated it probably wouldn't have felt so "squirrely".They didn't follow recommendations and critiqued as if they did. I think this video highlights the inconsistency of their reviews.
any problems and would u recommend this suv? i’ve read some pretty negative comments and now i’m second guessing
@@ava970 Just maintain it. I've had more troubles out of my F150 in 8 months than I ever did from my Jeep.
@@Larrybrwn so you’d recommend it? i’m looking at the 2014 limited or overland
@@ava970 Yes. I owned both. A 2014 Overland Ecodiesel..and a 2015 Limited Ecodiesel.
@@Larrybrwn oh wow. okay thanks!
Very nice camera placement!! She did not notice that it was aimed at her Camel-toe!!
Were you in tow haul mode?
Try it with new X5 40d or 50i!
what's the song at 1:00? thanks
Test the ram ecodiesel.
Some issues with the test. Peak power is at 4000 RPM. The transmission is programmed for economy, hence the great economy on the uphill. 15 MPG versus some of your other test trucks are getting 6 MPG?
Of course the 6MPG trucks will climb the hill faster, they are using three times as much energy. You must manually downshift for towing and keep the RPM at ~4000. There are flappy paddles for a reason. The car doesn't know you are towing almost 6,000 pounds. Keep the rev's at 4,000, it would have easily maintained 65+ MPH and would still have gotten 10+ MPG. The temperature rose so much because the car was seriously lugging.
For extreme towing you want max HP, not Torque. HP is WORK done over a period of TIME.
The temp rose due to the engineers at Jeep. I had the same heat buildup, and contacted Jeep. They said that is normal, and it will stay high, but not go into the red zone unless there are other problems. I towed in cold weather, and in heat, and the temp went almost to redline in both cases. But, it didn't overheat in the hot weather.
"For extreme towing you want max HP, not Torque. HP is WORK done over a period of TIME." WOW seriously you need HP not Torque I guess that would explain why semis have 650hp and over 1500 foot ponds of torque guess they all got it wrong!!!!
Vitali Tchikichev The only thing that is wrong is your understanding of what I said and the topic at hand.
Well do care to explain. I simply quoted you're line and brought reall world extream towing vehicles as an example which said exact opposite of what you said. It is possible I understood you're comment wrong.
Vitali Tchikichev TQ and HP are interrelated. HP = Torque x RPM ÷ 5252. TQ is what get's objects with a lot of mass moving. Once moving, say as in this test trying to get up a mountain, you want the engine to be at it's most horsepower. POWER is the measure of how much WORK can be done in a specified TIME. A good pictorial is this diesel engine:
afepower.com/catalog/54-30392/graphs/54-30392Dyno%201600.jpg
Peak TQ is at ~2,000 RPM. Peak Horsepower is at ~2,700 RPM. For starting an object with a lot of mass moving, you want to be at ~2,000 RPM. Once the object is moving and you start to climb a hill, you want to be at ~2,700 RPM. Ever heard a semi go up a steep mountain grade? It's RPM's are high (for a diesel) at it's most HP, not low lugging around at low RPM's at it's most TQ.
Hi it needs a tow hall mode for sure would do much better .
Anyone have one of these and use it in cold weather? I want to get a diesel eventually but I am afraid of the whole diesel turning to wax issue in the cold.
+leadnsteel A non issue, unless it's consistently under 0°F. If you have true concerns, then add 6-8 oz of Power Service White to every tank int he Winter.
Test the Grand Cherokee Trackhawk, I have tow my 6000lb camper up there and it easily does the speed limit
ugh why does jeep insist on using these goodyear fortera hl tires as oe equipment on a lot of jeeps!? I bought a commander used that had these one it. It had 30k miles on the tires (if they were original), but they were probably 30 percent tread left. I couldn't even go up a very slight wet grassy hill with them (4wd commander..)
How does the turbo diesel do without anything in tow? I am trying to decide between the hemi and the diesel. I drive 70 through Colorado all the time with my wrangler, but find it doesn't have enough power over the passes for me.
+Rob Ford it's fun to dirive. I've driven ours through Colorado twice and it handles mountain roads effortlessly. Great road trip vehicle. My Wrangler doesn't do so well up steep inclines (large tires and under-powered engine).
Roger Mata Z
I you paid attention to the video, the temperature gauge was topped on the red zone. I am wondering why they continued driving the car, while the coolant was actually boiling.
Likely, it wasn't in the red zone, just very close. Mine does the same thing, but doesn't go red. If it hits the red, the computer will reduce power to the engine, and you are supposed to pull over. Have never had that happen, even though I have been just-shy of the red zone.
Test the Durango towing
I understand the test was to see what the limit looks like. I wouldn't lose sight of the fact that there are very few mid size suvs that can perform this same tow. The other suvs certainly can't disconnect the boat and get over 30 mpg on the highway. Also, anyone see the irony in passing the camper that can barely haul its own weight up the mountain?
What class hitch?
Old red Dodge towing RV blows by em at 14:00.
Didn't notice at first. Looked like towing on flat land.
Would normal drivers who tow not manually shift gears for better performance? Give me a break..
Where is the Ram 1500 EcoDiesel Ike Gauntlet towing review??????????
Sorry for the spelling I used Siri. I meant I have a 14 v6 jeep and I tow a camper trailer with it 4k dry weight.
for all that shit they talked about it, 15.3 mpg going up that hill with a maxed out payload is pretty damn impressive for ANY vehicle. i bet that raptor got around 8 with nothing behind it...
in Canada it's only rated to tow 7200 lbs .. I don't understand .. why is the US model rated to tow more at 11,000 lbs?
ze3bar my US GC Summit is 7200 on the door also
It borrows a chassis with the Mercedes ML series
So the lesson here is that if you have to cross the Rockies in your diesel Grand Cherokee you need to buy a smaller boat. Your typical 3,000 lb bass boat would be an easy tow with this vehicle.
Roman, did you mean 11,000lbs?
You wrote: "Extreme Ike Gantlet" Who is Ike and what is a Gantlet?
Chicago guy here, I hate driving in Colorado it's makes me a nervous wreck
Sorry... what was the mpg?
guys you should really try this with an Audi Q7 V12 TDi

3:28 um it doesn't have chrome wheels. We owned one and those wheels aren't chrome
Bet the 5.7 would tow better gas mileage wont be as good but youd have less trouble maintaining the speed limit
my old 7.3 powerstroke had 435 lb-ft and it towed up steep hills like nothing was behind it. probably twice the weight of the jeep.
you're comparing a 7.3 to a 3.0...
MuSh similar hp and trq numbers
USCisgay Yes, peak numbers are similar, but if you looked at the factory dyno graphs of the two then you will see why your old PS 7.3L out towed this engine. The Ecodiesel 3.0L was originally developed to go into Cadillac cars as a fuel efficient engine alternative to the gas engine until the plan was scrubbed by GM. As a diesel meant for a car, the power delivery is rather peaky loosing a lot of torque after it hits it's 2,000rpm peak and it really takes a nose dive after 3,000 rpm. By the time the Ecodiesel gets it's peak horsepower it has lost almost 20% of it's peak torque making the power band very narrow. In contrast, the made for towing PS 7.3L has a flatter torque curve retaining most of its torque throughout it's rev range. It only looses less than 3% of it's torque by the time it hits peak horsepower which means you have access to a lot of torque for a much broader rpm range. So you see, it is not just about what the engine does at peak power, but also what it does at the rest of the rpm range that really matters.
alacey82 excellent comment.
I wanna see an Explorer take on the challenge although I'm pretty sure they only have a 5k towing capacity. And y do u guys have a boat in Colorado? Lol
do you think there are not lakes in colorado? Surprise! there are..
because lakes that's why
We bought one....and regret it
We are waiting for the Duramax/Cummins tuner folks to release a tune. They are almost there so hopefully it will come through
Just to clarify the fuel economy is great. We use my truck to tow so this doesn't have a trailer hooked up. The oil changes require special Euro oil that a lot of the imports have been using. Each oil change is over $160.00 and maintenance in general is HIGH COST. If your looking at buying this rig make sure you have extra cash for anything it needs.
C Nevs I have to disagree. I have one, and have had it for 7 months. I have 28,000 miles on it. I purchased the oil change package from the dealer, and changes are only $110. Since they are only done every 10,000 miles, they are much the same as a gasser at 3,500 miles. With the miles I drive, the fuel savings will pay for the engine in another 50,000 miles, max. My wife's 5.7 Hemi can't tow anywhere close to my diesel. For my needs, diesel is the way to go, and saves me money.
Duane Russell I can see that and respect that for sure. I would have to agree with you. When looking at the its not too bad. I have a duramax diesel and love it. I go 5000 and pay 90.00 so yes the fuel savings for us has been pretty darn good. I have seen a lot of recalls (relatively) on it though so i am a little gun shy.
Can't imagine how this motor would react in a much heavier Ram 1500. This motor should do well in the lighter GC but this motor just does not have, as Nathan would put it, the "ghoines." This EcoDiesel is starting to look like an EcoDissapointment.
Sunroof Holla!!!!!! lol
I've always instinctually thought chrome was used to gloss up a pig, in other words, when there is something wrong underneath, they try to hide it by covering the car in chrome.
Now I know this grand cherokee is REALLY nice, and is based on the Mercedes ML.
But I still have an aversion to chrome. To me its gaudy and take away from the engineering that went into the car.
Now, Ford using a aluminum alloy is a different story.
Now try the Hemi as the direct competitor...
