In November, 2019 I bought a 2020 Jeep Grand Cherokee Trailhawk with the 5.7 Hemi V8. I originally wasn't going to get the Hemi because of increased initial cost to the vehicle and fuel economy. But I changed my mind at the last minute. It wasn't because of the towing capability. I wasn't planning on towing. I liked the idea of extra torque. Also, I had never owned a V8 in my life. I'm 70 years old and tend to keep my vehicles for a long time. I figured this was probably my last chance to ever drive a V8. So I went for it! I'm glad I did. For me, having a V8 is more fun to drive. I like the idea of when I pull out of a shopping center parking lot onto a busy street with legal speeds of 45-50 miles per hour, I push the gas pedal and it goes! I don't worry about anyone driving up my back door because I can't get going fast enough. I drive in Sportmode almost all the time. When driving at a consistent highway speed on the Interstate, I will leave it in Ecomode. The only issue I've had is when in Sportmode, it occasionally downshifts hard. Sometimes it's very hard and startles anyone riding in the Jeep. It doesn't do it all the time which makes it hard to diagnose. I've raised the issue to the dealer's service department but they can't find any problem. No other issues yet. But because of COVID-19 I really haven't taken any trips. And being retired, I don't have to drive to work everyday. So I only have about 4700 total miles in my first year of ownership which is unheard of in Southern California.
I love that you’re in sport mode all the time! Good stuff
Yeah the transmission shifts faster and holds gears longer which increases rpm ranges causing the transmission computer to react in less than a second, the issue is all those moving parts have to mesh as fast and it locks hard, but it is not a defect. It’s slamming gears like one would in a hot rod with manual shifter.
@@toddbrown2574 Thanks for this, I was worried about it myself.
I just got a 2020 Summit with same engine and was worried about the sport mode downshifting myself.
Just saying, before I put the supercharger on my V6 2012 grand Cherokee, it accelerated VERY quickly for a heavy SUV with a V6. The V8 in my eyes is not needed (I don’t tow and occasionally I fold the back seats down and haul). I only added the supercharger because it’s not common. I basically make more power than a 5.7 right now, but even before it, it didn’t need it. It was fast AF then and it’s fast AF now.
Thanks Brad! I appreciate the review and your time.
You’re welcome!
I swear I was just searching the web trying to find any information on the differences between the V6 and V8 and came across this video. Great timing and information, it was exactly what I was looking for and answered many questions I had. Thank You!
Awesome! Glad we helped out!
Another great video Brad, lots of excellent points. My story is that I bought a 15 GC with the v6. Loved it, plenty of pep around town, great gas mileage and towed our pop up trailer no sweat. Then I rode in my buddy’s Hemi Ram and even jacked up and on big tires that thing would pin you in the seat. I’ve always been a gear head so I knew right then I needed a Hemi too. I found a fully loaded 17 GC with low miles during the height of lockdown and the dealer sold it to me for basically what I paid for the relatively sparsely featured, older, higher mileage v6. Now I have 2 GC. My wife loves the v6, it’s perfect for what she needs. I love the Hemi especially now that we tow a significantly heavier trailer that would have absolutely maxed out the v6 but the Hemi doesn’t even know it’s back there.
A few points about the v6, it’s tremendously capable Offroad, maybe even more so than the v8. It’s has lower gears, 3.45 vs 3.09, so with the torque multiplication I feel it makes it peppier at a lower rpm than the Hemi. The v6 feels just as fast off the line with the lower gears and can crawl better than the Hemi. The v6 also gets a higher payload on all the models. The 200lb the Hemi adds subtracts from your payload on the door sticker. So for over-landing like Dave, you can actually safely add more things to your Jeep without going over your max weight. The v6 handles better, the entire weight of the engine is even with the centerline of the front axles, the 2 extra cylinders of the Hemi are out past the front wheels and pushes the front end more in turns. Also as Brad mentioned there is room on the v6 to add onboard air. I’d rate them evenly on reliability in my experience so far. At work we drive v6 chargers that I know are driven like they’re stolen and the maintenance schedule is more of a suggestion and we have many cars well above 100k and they just keep running like a top.
The Hemi is the way to go if you tow heavy. Adding all the skid plates and offroad gear didn’t have much effect in my opinion, the biggest difference came when I swapped from street tires to the Wildpeaks. The added rolling weight affects every aspect of the driving experience. It feels slower when flooring it, feels softer in the turns and braking has been affected reigning in the extra momentum of the rotating weight. But I wouldn’t trade the v8. I’m looking forward to the next GC set to be announced on 1/7. It’s gonna have a 3rd row and slightly longer wheelbase. Only having 2 rows of seating is the only thing that I find fault with this platform.
Great comments! Thanks foe the input!
So would you say the v6 could tow a 5000 lb boat with trailer and gear? I'm buying this car with the intent to tow a boat specifically something like a tracker v175 .
@@brianb3910 Absolutely. The v6 with tow package is rated to tow 6200lbs and I believe it could no sweat. We towed a 2000lb popup behind my wife’s v6 and it didn’t even know it was back there, I know it’s way lighter than your boat but the v6 didn’t struggle. Maybe if you’re going to be towing up in the mountains you might need the diesel or Hemi since the smaller engine will struggle at altitude but otherwise you’ll be fine. The Grand Cherokee is a great tow vehicle.
Thanks Brad and Dave, all your information was good to know!
Glad it was helpful!
Love the last segment w/ the "Chief Products" guy!
Thanks for the video, it was informative and well done. I’m just now coming off a 39 month lease on a 2018 JGC Overland w/5.7 Hemi. I loved this suv so much that I just purchased it at end of lease 👍🏻
Good stuff!
I just traded in my 2015 cherokee trailhawk v6 with hazard sky lift for grand Cherokee limited 4x4 hemi quadradrive. Loved the trailhawk and it could pull my 21' boat around town (3500lbs) but struggled on trips with the small tank. Found this GC without quadra lift. Enjoy the vids. Learning a lot for building my gc now. Thanks.
Had my 2014 Ecodiesel since new and it’s never missed a beat. Tows like a tractor, effortlessly overtakes at highway speeds and can get 7L per 100Ks at 90kph. The only down side is little turbo lag on takeoff and that diesel rattle (that you hardly hear in the cab). Here Australia the diesels are by far the more popular engines for 4x4s.
Get yourself a throttle sensitivity booster. BD diesel makes one that will change that laggy feeling for a few hundred bucks. My wife was complaining about the same issue on takeoff but now its a rocket. Engage ludacris mode and enjoy that torque on tap. Safe travels!
I mounted an ARB twin compressor in the engine bay of my 18 Trailhawk with the v6. It required replacing the stock air intake with a K&N cold air intake. That opened up a ton of real estate.
Great video, Brad! Thank you! As another data point: The dealer just replaced lifters in my '18 GC TH HEMI at 23k miles due to ticking sound during startup. I did get the lifetime warranty option when I purchased mine so that repair and future repairs don't cost me any "more" significant out-of-pocket money. The dealer supplied me with a rental during those couple of days that they paid for. That said, I do like my HEMI purchase, and I would do it again. There are a lot of good points throughout your video and in the comments. I have towed my 5,000+lbs. '95 XJ with my '18 GC TH HEMI. In 3-4 years, I plan on getting a trail trailer to pull behind my '18 GC TH HEMI for longer trips on the Rubicon, etc. Before I bought my HEMI, I rented a similar GC with 3.6L Pentastar... when it came to buying my own, the HEMI purchase was an easy decision for me. To elaborate, the Pentastar engine has more than enough "power," but it has to work hard to deliver it, even in daily driving. In contrast, the HEMI engine performs everyday tasks easier, doesn't have to work as hard to deliver power. Like a kid in a candy store, I'm happy that they now offer a HEMI in the wrangler trim! I've already started my savings jar ;)
Thanks doe the added information on the lifters! I really appreciate the great comments. Helps everyone
all 3.6 are rated for 6200 lbs of towing with the tow package which includes heavy duty engine cooling, trans cooler, & NIVOMAT by Sachs self leveling rear suspension. I'm on my second WK2 with the 3.6. It's a reliable strong engine and has no problem on the trails. Guys are running 40" tires with this motor & trans in Wranglers with no problem. The later ZF 8 speed transmission is key to making the Pentastar a great performer. If you're towing get the V8 but if not , save your cash for beer & mods and get the V6
We have 3.6L's little brother, the 3.2L, in our Cherokee KL Trailhawk. Love the engine. Smooth and enough power a torque for our wants and needs.
I miss my 2001 straight 6 grand cherokee
I miss my 4.7 HO
Amazing Jeep. The 4.0 was bulletproof
i love my jeep 2001
My old Jeep Laredo with the 4.0 lasted me 20 years. After 250k miles it still ran great. I gave it to my nephew. I wish they still offered that motor. In my opinion, best motor ever built.
Me too- my '96 GC had 240K when I sold it. Ran perfect, didn't use a drop of oil. So incredibly smooth. Pretty happy with the 3.6 in my 2016 GC though!
My 2014 3.6L had bad valve rockers right at 90,000 miles. The extended warranty I bought took care of all new rockers and new cams. The only other issues were common. Now, it's at 100,000 miles and little things are starting to break. The AC evaporator started leaking, the EVAP purge solenoid went out and both climate control actuators. All fairly inexpensive and easy to fix. The 5.7 gives you that nice lower-end torque. The 3.6 is peppy though, especially in the 2300 - 2700 RPM range. The transmission helps a lot. Sport mode is a must in certain situations.
I test drive both v6 and v8 before I bought my new GC 2020, I got the v6 because it is slightly cheaper and better gas mileage. I use it for daily drive to work and grocery store only, but because I live around the desert, I do sometimes go off road on the Sand. so having a low 4WD is needed. I am sure I made the right decision going with the V6 because I don't do any towing or hauling using my jeep. I think the only thing V8 is better because of the engine sound is kind of cool. and the v6 is very good on sands it is strong enough.
Yes! Thanks for watching!
My first car was a 73 dodge dart sport with a 340 and ram air intake, followed by several ramchargers with a 318, and the 5.7 hemi in my 2011 grand Cherokee is the most awesome engine I've ever owned, including mustangs and trans ams. This engine screams and so far has been reliable, although every part you have to replace is extremely expensive. Every time I turn around I'm having to spend hundreds of dollars, and most recently I had to spend $500 for an alternator. Also I just spent almost $100 for Mobil 1 synthetic oil to make sure I don't have camshaft failure. In 30,000 miles I've spent thousands of dollars to keep it on the road. It's literally turned into a money pit .
I have a 2008 Jeep Commander 5.7 Hemi Overland with QDII. Original owner, and still loving it. It has the original motor an tranny, and runs great with 250k miles. I'm now having to add a quart of oil every 1000 miles or so, but it feels as strong as ever. I have towed trailers with it and wheeled at Moab. It has a 2 inch lift, which I really like. I'm glad I have the Hemi to tow and haul up to 7 passengers. The only downside is gas mileage.
The V6 is excellent.👍👍 Ihave had Hemis too. 👍👍👍All good👍👍😎😎🇺🇸
Yet another great video, thank you. Ordered my brand new Grand Cherokee trailhawk in 2018 with the hemi. Drove both hemi and v6, both had adequate power. I've pulled 6-ft by 10-ft utility trailer load of mulch with both. There again they both did fine. Now the hemi definitely does better. To me it come down to gas mileage, versus raw power. My wife and I don't travel a lot. Generally put on around 5,000 mi a year, if that. So I chose the hemi. Most of our driving is back and forth to work around a small town,we average around 16 mi to the gallon.We did take it on a trip, from Central PA to Maine. An average 24.4 miles per gallon. Was pleasantly surprised. My niece just purchased a brand new Grand Cherokee. She has a much further commute to work, on backcountry road. So my recommendation to her was, get the v6, and stay away from air suspension. Hopefully this helps you choose, and thank.
Also wasn't expecting that I had to run minimum of 89 octane in the hemi. Didn't know that till red owners manual.
Great stuff. Thanks for the comments!
3.6l is an amazing motor. Very simple, bullet proof! Great mileage as well.
Bulletproof? Lmao did you not hear about the massive rocker arm problem they have that Jeep refuses to take ownership of?
@@franksmith8210 I had a 2013 GC that I had to pay out of pocket to replace the lifters. I'm worried about getting another GC. anyone know if this problem was resolved? I'd love to get a 2019-2020 GC.
Gordon D yeah the newer ones fixed the issue. Still not a fantastic engine though. If I was getting a new GC I’d look at the v8 or the diesel.
@@franksmith8210 - I didn’t realize the V-6 had massive rocker arms ...
@@tekc0der I have 200k on my 3.6 2015 and zero issues. Sooooooo
Great review with no BS thrown in! Thanks, going to work on a deal for the GC Trailhawk 5.7 tomorrow. Not exactly a buyers market but with a Rubicon trade in should be interesting!
Good luck!
The V6 is fantastic looks the same and I've got custom made armour bumpers with front grill guard protection and side armour . I also use chief products roof rack and full skid plates. In winter It was rear ended the car that ran into my custom armour was a write off. I drove away with nothing but a small scuff. It's a beast I went for a slow and steady beast heavy but is a zombie apocalypse vehicle I should put pictures up it's a one of a kind. Most if not all vehicles have no protection except plastic bumpers I got rid of the plastic and went with full metal custom armour .
It is now June 2022. I bought my 2018 Trailhawk 5,7 hemi in July 2018 (four years ago). I don't have many miles on it (retired and we usually drive my wife's Camry). ---- BUT ---- If I keep it below 75 on the hwy, I get 22 mpg. Around town (lots of traffic lights and stop signs) the mileage is pathetic --- 14.5 mpg. I do pull a trailer --- 18 foot IO Searay boat, and a 22 foot travel trailer (no, not at the same time!). I know they are there when pulling them, but it pulls fine. I can't imagine what it would be like pulling them with the V-6, so I am very glad I got the V8. I got all the bells-and-whistles, and the electronic are great (crash avoidance, adaptive cruise control, etc, etc). I have never used the automatic-parking feature, but all the rest are great (I love going to the apps page, and can see all the temp readings --- very calming to know I am not overheating anything while pulling the trailer, --- or to the vehicle tilt angles, etc). Sadly, there are so many 'electronic things' I have forgotten how to even use (or get to) half of them. I do get the 'hemi tick' occasionally when starting up --- not a concern. A great car!
TIP: I just found out that there is a hidden compartment (just like the passenger under-seat battery compartment) under the drivers seat. Tomorrow I will check it out ---- a great hiding place for 'little used things' (I hope).
I had a 2012 GC Overland Summit. I loved that thing, it was a tank. With my 5.7, I ran into a camshaft and lifer problems. It became a pain after that.
I've got a 2017 Grand Cherokee Trailhawk with the 3.6L V6 engine. I've had it for under two months, gone off-roading a half dozen times, and this is my impression: with the horsepower, the torque, and the various off-road 4x4 modes, it's quite versatile, has really good acceleration, and has powerful performance. I've had no problems when I head up to northern Wisconsin and encounter snow and ice. It does northern Wisconsin's hilly off-road trails very well indeed, and with the thaw I've cut right through those muddy trails like a knife through butter. And it's worth noting that I have the stock Trailhawk tires (Wrangler with Kevlar), which aren't even operating at peak performance because of daily wear and tear from the previous owner. And if you put the GC in Sport Mode it has some pretty serious acceleration from standstill. I'd say the V6 makes the GC a great everyday driver with pretty good fuel economy, but also an off-road 4x4 option that doesn't flinch with varied terrain. Now, I haven't take it on the off-road trails seen on this channel, so I can't speak to its performance in those conditions, but I plan to try.
Thanks for the feedback!
Thanks for your videos I really find them to be the best to watch and learn I currently bought a jeep grand Cherokee Limited 2019 with 40,000 miles on it and I couldn’t turn it down for the price. It does have Quadra track 2, mud rocks, snow, etc. hoping it’s a decent, 4 Wheel Dr. for off road with the right tires
Have the 2018 trailhawk V6, good to know Brad. Feel more confident off-roading now.
That’s great! Have fun out there!
Great video 🚘
Thank you!
Of course I see this video as soon as I buy a 2014 V8 overland
Awesome content, thanks for all the work you put into this man!
I have a couple questions for you:
1. Payload limits: with adding gear to the vehicle, are you worried about being over payload limit when towing with a family?
2. V8 for towing: do you think the V8 would really be needed for towing a 3500lbs (dry) trailer?
fully loaded with gear and a trailer we were over weight. As far as towing look at the gvwr instead of the dry weight. When determining which engine to go for. Hope that helps!
I'm not sure that enough data is out to say one engine is more reliable, however, two meetups ago, a guest of Brad's had the Hemi and a tricked out exhaust. Man I could listen to that all day! If you don't tow, say more than a side by on a trailer, I think the V6 is just fine. I have the V6, and with the 8 speed, it is a beast off the line. I have gone against a number of Hemi rigs (off roading), and without blowing up Brad's skirt.... Its the driver off road... period. Brad knows his Jeep. Learned a lot from him. Yeah articulation is certainly a player, but the WKII, as I am learning, is an incredible off road machine. Nice video. And good "political" dodge on saying which one is best! Folks, if you can make a Prodigal meet up, you will learn neat things about your Jeep. See ya soon.
Good words of wisdom! Thanks for the kind words!
Hi Brad, another great and informative video. Thanks for making these it really helps when people are looking to buy. I have a question could you explain or do a video about the differences between the quadra drive and quadra trac systems? Can the center and or rear diff be locked and can that be done manually or is it automatic? Do you get a display of when they are locked? What about the front? Also a big hello from New Zealand, where I am! We have all the different Jeep GC’s though I haven’t seen a trail hawk yet. Only difference is the steering wheel is on the right side 😁 cheers, Mark.
good questions, and good idea for a video!
I've got a 2009 Grand Cherokee 5.7L and I love the power and QDII system. I tow a car trailer with it and it does a great job. Unfortunately at 173k miles it had the lifter and camshaft issue you described. I tore it down myself and its back on the road now but it definitely diminished my confidence in it. From what I've read, the hemi was revised in 2017 and had improvements that solved that issue so you should be good.
Good to know. Thanks for the comments!
Thank you for your Hemi update dude!!!
So if I am going to buy a hemi that was produced before 2017 it is likely to have this issue? Right?
Thank you for the great video. I'm trying to decide between a GC and ram rebel truck. I'll go with v8 after watching this for sure.
Happy shopping! Glad I could help
Those were the two options we were looking at. But the incentives for GC were just better at the time.
I've had two 5.7 Hemis so far(Charger and 300) and loved them both. If I go for a Grand Cherokee, it will be Hemi #3.
I’d say most if not all off-road capability differences are found in your differentials and gearbox. Not necessarily about how much power you have but how it’s being used down under the car. I have the 3.6 and tow a 3200lb boat pretty easily, but yeah any bigger of a boat and I would need more torque and bigger brakes
The 3.6 has been good in my experience. I've got 185k on my 2015 trailhawk cherokee. It dropped a lifter around 160 k but most people won't hit 160k on their car. Also my brothers has 187k and his lifter has been fine. My 2000 gc has the 4.7 with less hp and it pulls fine too. Gearing makes a big difference so getting a tow package or something with the shorter gears makes a big difference. Great video, thanks for sharing
Thanks for the feedback!
@adventures with Daniel can you compare driving experience between your WJ and WK2?
@@craigtupper103 I have a cherokee trailhawk not the grand cherokee. I have driven the wk2 several times but I don't own one. I can give you my thoughts based on my limited driving experience with the wk2 I'd you'd like
@@AdventuresWithDaniel I see! I currently daily drive a 2004 limited 4.7ho with Quadra drive. With just shy of 400k km on the clock. I keep thinking a wk2 is the natural progression. But I drive muddy woods roads daily and also want better fuel economy and tow around 4000lbs. So the 3.6 is appealing as long as it's up for the towing.
@@craigtupper103 the 3.6 is a GREAT engine! I'd say pulls as good as my 4.7. It's not as torquey but the transmission really helps keep the engine in the power band. If you're hauling heavy stuff I don't think the wk2 is the best platform but if you're pulling a trailer 3500lbs or less or hauling the usually camping and offroad gear in the cabin and cargo areas I think you'll like the 3.6. I've got 196k on mine. I dropped a valve at 160k or so but it's been very good. My brother has 205k on his and he's had no engine work done. The wk2 is a very different vehicle than the wj. I love my wj with the iron rock lift. It drives smoother than my cherokee and does better off road but the wk2 does very good in its stock form and drives very nice on the road. Especially with the quadra lift suspension. I'd skip the wk and go straight to the wk2 if I were updating my grand cherokee.
I plan a either a turbo or a ripp sc on my 3.6 at some point. 👍
I have heard about the trailhawk air suspension being bouncy. I can see it it. I had a jku with the 3.6 and with 35s it was not bad.
Our 06 GC limited with the 5.7 runs much smoother and quieter on 89 octane.
The hemi tick is from the exhaust manifolds.
My only gripe with my 2018 GC I purchased 2 years I had to get my thermostat replace once and my water pump replaced 2x within 11 months of owning it other then that it's been good vehicle luckily I had extended warranty
I have a 2.4 regular Cherokee Trailhawk. It has WAY WAY more power than it needs off road because of the gearing. (56:1 crawl).
Honestly , the biggest concern is cooling. You're not going very fast and if it's hot out and you climb and climb and climb ... It gets a little warm . Never overheated but the transmission gets hotter for sure.
It's never power that I worry about , it's cooling - as far as engine and transmission go.
Nice video, plz make a video about the lift kits for the wk2 equipped with air suspension, and what max size tire possible to fit in there.
Good idea. I’d have to do some research on that one. I’m not sure there are currently any kits besides airlines to add some height
Google says .. if u have the 18inch wheels that a 275/65R18 is the biggest you can go. That's what i have on mine.
@@daltonrobbins3387 I have the BFG 275/65r18 k03's on my 2017 GC Trailhawk 5.7l. I've done many trials in th GC that I have also done many times in my old Rubicons, and it's been perfect. Not tire rub, no problems at all.
What would be a better motor for my Skyline, a Gallo 12 or a Gallo 24? 😬
Great video Brad!
😂🤷🏼♂️🙄
I didn’t know pizza places made engines
Hey, how about the 3.0 CRD ("Diesel") engine???? I LOVE my 2015 WK2 EcoDiesel Overland w/ OFF Road Adventure II (w/ "Quadra-Dirive II") and lots of Chirf Products and other Off Road Add-Ons!
Hi Brad thank you for your video!
I have purchased my 2020 Jeep GC Trailhawk with Hemi in May 28th.I decided to take the hemi in long term because of higher reliability . My previous car was Hummer H3 3.7 liter. The main reasons why I decided to trade in my Hummer were #1 i wanted v8 engine,more power! #2 very difficult situation with finding some new parts.
I have been taking my Hummer to a lot “middle” trails, and a little bit i gave a try to my Grand Cherokee. I was not disappointed with my choice that i took Trailhawk with hemi over 4Runner Trd Pro. Great engine,pulling effortlessly,cool air suspension,drives like Range Rover and very capable,stronger transmission,Hemi “kinda” has been improved in 2017 with Hemi ticking.
But here are some moments that makes me sad 😢
#1 my hemi 0-60 times are literally 8.0 seconds average. Well i am 315 lb man and i have only 8700 miles on my GC, but i was expecting about 7 seconds,but in fact hemi 5.7 drives as fast as 3.6 pentastar...i was surprised!! Hell sometimes i see a nightmare that 3.6 is faster in 0-60 that my 5.7 😩
#2 my mpg. I try to drive always with eco mode off.Sometimes i floor my gas pedal all the way down. Right now i have 9.3 mpg,.The car is completely stock. In summer and autumn i have had 9.5-10.5 mpg. When I tried to drive very and very careful as a “sorry for that” retired old man,maximum i got is 11.5 mpg in city.. one time..
But in hwy at 70-75mpg cruising i have 22.5-23.5 mpg maximum..That is really cool!
#3 the alpine sound system.. Brad if you are reading my comment here,please let me know your equalizer settings like bass,middle and “high”(?) settings, and does you surround sound turn on or off? Thank you!
Just in my Grand Cherokee my alpine system sound poorly...my hummer h3 played better,more clear sound.
Thank you for your videos!Let God Bless You and your family!
So my overall conclusion...Overall i like my grand cherokee trailhawk with hemi) just couple moments :)
For those who want to buy hummer h3 3.7 liter, in city 12.0-13.0 mpg,in hwy 15-17 mpg, depending how many people are inside etc. and optional cruises control speed should be no more than 60-65 mph, higher speed = a way lower mpg 😅😂
Thanks so much for sharing! I totally agree with your #1. As far as the sound system. It’s way better than my previous car. (Honda civic) 🤪 take care!
I love my 2017 GC trailhawk with the 5.7! I got like almost 20k of shit I'm gonna be buying to upgrade both Offroadring capabilities, and the engine. My wife also has a 2018 GC altitude with the 3.6 i believe and she loves it. Granted she doesn't off-road it lol but oh well, as long as she loves it.
Good stuff!
There isn’t even 20k worth of shit out there for the GC
Hey if you are ever around Kentucky and would like to go on a trail and compare the 3.0L ecodiesel trailhawk to the 3.6L let me know!
Also, near as I can tell, the 5.7 weighs about 250 lbs more than the V6, for a lot of extra weight over the front wheels.
The fact is the 5.7 is behind the times. A V6 Honda Pilot is quicker to 60 than the 5.7 GC, mainly because the bigger Pilot is almost 1000 lbs lighter. And, why does the 5.7 make 30 more hp in a RAM pickup?
Even in highway driving, keeping mpg above 20 with the 5.7 is a challenge. If you plan to commute, the V6 is probably better. I'm glad I got the 5.7 in my TH, but it's certainly not what it could be.
I'm also disappointed the next gen GC will, apparently, have the same engine line-up.
Can we get a link to Dave’s GC rock rails?
On start-up, that’s pretty normal.
The 5.7 is a fairly large engine.
It takes a bit (30sec-90sec) for the engine to send oil to the top-end.
My opinion is buy what suits your needs. I have owned 4 Jeeps with the Pentastar engine. 2012 JK Sport S, 2014 JKU Sahara, 2018 JLU Rubicon and now a 2020 WK2 TH with the 3.6. My needs don't involve towing anything. Here in Canada the Hemi option cost an extra $3,000. The 5.7 adds about 150 lbs of weight to the WK2 and only gives a extra 65 hp and 100 ft lbs of torque over the V6. Not to mention cylinder deactivation system that has caused Hemi engine issues as well as failing roller rockers destroying 5.7 V8. Just my 2 cents I will take the 295 Hp Pentastar.
Thanks for the comments!
I've taken my 3.6L Trailhawk all over Arizona offloading and it handles everything without issue. I'm actually thinking about stepping up to the 5.7L Trailhawk just for on road capability. Although the 3.6L has more than enough power and acceleration to do whatever you'd like. I'm thinking overall and I think a supercharged 5.7L Trailhawk would be a monster.
The V6 models create more torque on 4Low due to differences in gearing in the transfer cases. The V8 models have more power on 4High. So it just depends on what you plan on using your Jeep for If you're towing go with the V8, If you plan on spending most of your time off road climbing things then get the v6 model for the advantages It gives you in 4Low.
Interesting. I had no idea.
Yep, 4 Low is there for a reason. It's unfortunate alot of people don't really utilize it and stress there transmission and engine out more than they need to.
Runs some MMO oil in it the keep the lifters clean so the don't tick
What is your experience regarding the fuel consumption between the 3.6 and 5.7 realistically? How is the difference?
You don't need a V8 or a v6 to go offroad. Probably the best offroad vehicles I've ever owned was an 86 and a 93 Toyota 4x4 truck with a 4 cyl engine. I bought the 93 just one month before the blizzard of 93 and even multiple feet of snow didn't stop it and I passed plenty of jeeps and other vehicles on the side of the road, however I absolutely love my 2011 hemi grand and know it has the capability of going anywhere
My biggest question is how the guy at the end fit 33" tires on his rig.
Very informative Video. Thank you. Me, as a German, was shocked to hear about the 17mpg you get in your 5.7l
In my 2018 Overland Diesel I get around 29mpg. When using the German "Autobahn" I still get 22mpg.
I guess you mean 17mpg while going with your Camper or offroad?
I installed my air compressor at the trunk hidden behind the rear seat on the right hand and guess what! I use the air suspension nitrogen Cylinder as an air tank after I canceled my suspension and put lift dobinsons ims... Other thing is the hemi 5.7 is more reliable than the 3.6
That’s a creative use of your nitrogen cylinder! Good stuff
So, just took delivery of my 2021 GCTH with v6 yesterday. The ride is way better than my 2017 Toyota 4Runner TRD Off-Road. It had better power from what I can tell. Interior is definitely higher quality, gas mileage seems about the same, and the Quadra-lift is a plus IMO. The negatives vs the 4Runner: love the rear cargo lift gate window better than the GCTH, and the backup camera is better on the Toyota, and the rear tire being beneath the 4Runner is better than the GCTH having the wheel inside. But overall, I’m happier with the GCTH than the 4Runner. Let’s see how that goes after the first 6 months passes.
Thanks for the comments. Good information!
@@ProdigalOverland I want to add that we took the GCTH on a 1,000 km trip today as a break in drive, and the range on a single tank of fuel is absolutely better than the 4Runner…hands down. This is a side note item because I don’t know if more upscale models of the 4Runner have this option, but the 2-memory-position driver seat recall is very handy when long trips call for changing out drivers. It’s a small thing, but I didn’t have that on the 4Runner.
Ive owned the SRT and now a 3.6 Blackhawk. Save your money and get a 3.6 unless you go full hog for the trackhawk. 3.6 isnt slow in sport mode and it goes offroad very well. The 5.7 maybe as it goes offroad but the elephant up front dont help in sand. I cant comment on the 5.7 as ive not owned one. Weight is everything. V8 sounds good though, do miss the growl but dont miss losing my licence, constant visits at the petrol station and everyone wanting to race you.
3.6 wouldnt be an issue towing 😂 i had a 3.8 wrangler and towed a camper tralier around Australia on all the offroad tracks - had not 1 breakdown or problem.
The 3.6 tick is about bad rockers,once changed with the new ones, all good. Its $2000 Aus per side if the cams need replacing / worse case scenario at a jeep dealer, wouldnt recommend anyone but the dealer or you might get the same rubbish they used years ago, so they earn $ from it, unfortunately there are still the standard cheap rockers out there. Jeep dealers wouldnt dare do install them and cover it.
If you buy a used jeep 3.6 get an after market warrenty as this covers the problem with no problem - Integrity warrenty are great, standard cover is good enough. If you buy one private check its been done - simple.
The 3.6 ticking thing isnt that bad compared to what happens with other offroad SUVs, especially Landrover, BMW, New Hilux and mazda BT50s. Its only because you want one you google about it - every vehicle has issues these days. Once the 3.6 is fixed from ticking its brilliant.
I’m interested in buying a 2015 summit v8 4wD thanks for the review I feel more confident !!!!!!
Glad I could help!
How many miles can you go with the V8 Hemi before needing gas? I understand that it’s less fuel efficient than the V6.
mixed use on my 2014 3.6 is 22mpg
Question for you, do you pull your camper in sport mode? any advice on towing with grand cherokee, eco on or off, sport mode?
We would tow with the eco mode off, I did not have sport mode on. It did great. and we installed the Tekonsha P3 brake controller. Also a big fan of that one.
My 5.7 ram had a tick at cold idle then went away also. Now enjoy the 16 spark plug change at 60k for ~$800😁
Yes so I hear, I haven't done that one yet
@@ProdigalOverland I was forced to when one crapped out and all have to be changed. I would do it as a preventative maintenance with all the travelling you do.
Oh yeah the hemi bro !!!!!
5.7 is fun.....
Brad, your GC is an '18? Mine is too, but that color (Destroyer gray?) was not available when I ordered mine.
No. It’s the rhino color.
When you say to be weary of the 2014 GC, is that both platforms or just the 5.7 Hemi?
Here is what I found on this. www.carcomplaints.com/Jeep/Grand_Cherokee/
Hey Brad, really enjoy your videos, thanks so much for providing this content for the community! I just switched from a 2018 GCTH with the 3.6 V6 to a 2021 GCTH with the 5.7 V8. I was always puzzled on paper why the considerably higher displacement wouldn't bring out more power than the 360 and I didn't expect much of a power difference between the 295hp of the V6 and the 360hp of the V8, especially because both are naturally aspirated. My DD is a 2017 twin-turbo 4.4 V8 with nominally 560hp (in reality considerably more) so I always felt that the Hemi must be an extremely reliable and techincally underpowered engine.
My personal take on the two engines for the GC Trailhawk:
1) Both are plenty sufficient for every day use
2) For regular on road driving, you can feel the additional "oomph" of the Hemi in low RPM acceleration, bear in mind its much higher torque across the power band
3) Fuel mileage is surprisingly close on both in my experience, definitely on highway travel at 93oct
4) The Hemi's sound is the tamest V8 sound I have ever heard, so don't expect much of the usual V8 growl not even on cold start, I was considering tweking the exhaust but since I plan on extensive overlanding use, I like the very small "acustic footprint" of the vehicle. It really is the mildest V8 on the environmet sound wise that I know of.
5) While the V6 was perfectly capable of taking on any of my moderate green/greenish-bluish off-road challenges, the Hemi just takes obstacles with more of a reserve sense. Higher torque can be an issue in muddy or otherwise low traction situations but the Qudratrac II system handles that very well and then you just ahve so much more reserve to work with. I found myself a lot more often "fighting" and obstacle with added accelerator on the V6 than with the ease of deliberate crawling on the Hemi. Pure joy.
6) Surprisingly, the Hemi is overall louder than the V6 inside, especially on acceleration and doesn't necessarirly sound as effortless as you would expect from such a large displacement, relatively low output engine. On any midlevel to luxury sedan, going from a V6 to a V8 typically brings about a much more cultivated engine feel. That's not necessarily the case with the Hemi. So I am not sure if it is just psychological that the Hemi feels a tad more "planted" over the V6 not just because of the added weight.
Hope this additional input helps. Would love to meet you in person one day, only that I am way out in the North-East ;-/ But maybe at least at Rausch? ;-)
Best,
H.
Thanks so much for the input! And yes to Rausch Creek, probably in April or May. If you haven't yet signed up for our newsletter you may want to do that. It's on our website, that is where the most up to date info is.
I just found this video and it's great. I am very interested in your wk2 videos. I life in Germany and drive a WK2 Diesel myself - love that car (V8 is very rare, even V6 is rare. Here you find some Diesel V6 and some SRT. No wonder: gas price = 7,71$/gal and diesel price = 7,22 $/gal. So really happy about my 28,33mpg on my diesel v6).
So I would like to see a comparison V8 vs. V6 vs. Diesel on your offroad adventures and maybe a comparison of the gas/diesel consumption. Just an idea.
Get a cold air intake and you have the space for a pump
2006 jeep grand cherokee laredo 4.7 vs 2006 gmc yukon 5.3 race/everything we wanna see it!!
5.7 hemi all day. The v6 is a good engine
I drove a charger with this engine for 2 weeks it was quick pulled good mileage but have to go with the 5.7
We do enjoy that V8
Hey brad what is your payload on your Jeep? I am looking at one that is almost your twin and just wondering what your available payload is and how you feel about the trailhawk seats over the overland seats
Hey Tyler! sorry for the Delay The sticker on the door says 1050 LBS
@@ProdigalOverland so I ended up purchasing the Jeep and just wanted to say I love it and your videos are a big reason why I ended up with a trail hawk! Fun fact I looked at the payload on the Jeep I purchased and it has the same 1050 payload but it has the mopar rock rails from the factory 🤷🏻♂️
@@tylerarmijo4694 they probably just slap the same stickers on everything. I’m glad you got it. Enjoy!
In round numbers the 3.6 is about 150 pounds lighter which can be a thing off-road. If you're towing heavy I'd go with the 5.7 but if not the 3.6 is a decent choice. I've owned hemis and hated feeding them.
and according to the designer of the motor you're better off driving the 3.6 like you stole it from time to time --- can't hurt it.
It’s proven reliable! Thanks for commenting!
My cousin actually just told me the other day that hemis are very bad about not getting the cam lubricated good enough. Don't know how true this is, but he is a car guy wayyyy more than i am lol.
It seems like a thing.
question: does you r HEMI take 89 or 97 octane, the internet says 89 (mid grade) but what does your owners manual say if you still have it.
We run 87. No issues
I have the 2015 JGC overland.
But mine is not trail rated .
Does trail rated make a difference?
Can I off road 1-2 rated trails with out a
“trail rated “ Jeep ?
Short answer is yes. Just know that you are missing with skid plating and Quadra drive system. But on easy trails it will be ok.
Both the GC and the wrangler use the same engine and they weight about the same. Add extras to the wrangler and its north of 6000 lbs. The V6 has no problem pushing an lifted over weight wrangler and now with the 8 speed trans even better.
Yep. You got it
Don't forget the cost of spark plugs for the hemi having 16 plugs
My Grand Cherokee Overland had the Hemi tick, it turned in to needing lifters & a cam, 4K later I wanna trade it....for a 2021 Trailhawk V8. I'm absolutely disgusted with FCA for not recalling vehicles with those motors however, I fell deep in love with the Jeep. I'm a Ford guy when it comes to truck so that's saying something.
Edit: Mine has a magnaflow exhaust and boy does it sound mean, love turning heads when I start it, you don't expect to hear that rumble from a Grand Cherokee..
Very nice! Love a good rumble.
Oh; also . . . I DON'T do "Facebook"!
This guy could talk two hours and never tell you anything.
😂😂
What I've always thought about the idea that the 3.6 doesn't have enough power is that people that worry about that listen to non 3.6 drivers too much. My 2019 Trailhawk V6 does awesome in all conditions. It's bone stock and it's just me, so not overloaded and no trailers or anything.
Dunno how you think you could comment on a Jeeps power when you’ve never towed a trailer with it 😂
I’m waiting to trade mine in. Waiting for the Hurricane 🌀 twin turbo. 😊
So would you recommend the 5.7 over the 3.6 or what not sure what your saying here ...?
If you need to tow get the V8, otherwise the V6 has enough power for you.
2015 grand Cherokee 3.0 diesel all day long
you said to avoid 2011 GC Hemi engine? wow, Im about to buy that version. COuld you elaborate more? why the specific year of 2011 and 2014 need to be avoided? thanks
Hemi tick. The early hemi’s are prone to bad lifters flattening out the camshaft. Also the newer Grand Cherokees get an 8 speed transmission which improves mpg. 2016 and up gets an improved gear shift mechanism as well.
Edit: fuel pump relay was an issue on the early jeeps and the fix seemed like a bandaid with add on relay to bypass the one that kept failing. That was a recall a while ago.
Here is the info I had found. www.carcomplaints.com/Jeep/Grand_Cherokee/
My cousin has a 2011. Had to fix cylinder related issues twice. I had the 2013, no issues until 96k, lifters causing ticking noise. Was repaired under power train warranty. I now have a 2019 GC Limited X 3.6.
Would the v6 be fine to just pull around some toys like sxs, wheelers?
Yep. Absolutely
I was a fool and got the Ecodiesel. Never again. It has had so many recalls (though luckily no failures). I do not get anywhere near the fuel economy that I was hoping or heard about. The power is fine but not worth the extra costs. Also on a separate topic, air suspension though it is nice for the adjustable ground clearance, the ride on the dirt is just garbage. Those are the 2 big changes I would not repeat.
It is quite a bit more over the 3.6. Isn’t it?
@@ProdigalOverland Brad if you are referring to the power, it is less horsepower but double the torque. It pulls great and the turbo works super if you are at altitude. I have never thought it was slow...... diesels just don’t rev, which on the trail and normal driving is fine. The turbo lag to launch is where you notice it the most. If you are referring to the fuel economy, with mixed driving biased to hwy I get 24 mpg.
@@jaradderosa3252 I would have though more on the MPG. Thanks for the info!
People who think you need a V8 to go off road dont go off road, and/or dont understand how low range works. My current rig has a yota 4.7 and my last rig had a 5.3. I hardly ever get past 1/4 throttle in low range. I wheel with v6 and 4cyl guys that can do way more than I can.
That being said for the ride out and back, when you've got those off road tires, lift, 2 kids, 2 dogs, and gear for a week out on the interstate a v8 is a nice luxury. Especially trying to do 75 at 10,000 feet in the Rockies. Keep in mind you can only go as fast as the 100hp 4cyl on 37s that came with you though lol.
This exactly, Thanks and good points!
How much is it for an oil change with the v8 and does it take conventional or synthetic?
I use full synthetic. It takes 7 quarts. I do it myself to save some money. It’s not hard.
Gearing....I changed the transfer case gears in my old Trooper and it made it feel like it had a V8 with low end torque in low range...but it still had the super weak 3.2L V6 (~160hp). In high range with 33" tires.....3rd gear over the I-70 passes in Colorado...yikes!
Yes! I tried to find the gear ratios on the 3.6 but couldn’t find it anywhere. I believe the v8 has different gearing.
@@ProdigalOverland The 3.6 engine comes with lower 3.45 gears and the 5.7 comes with 3.09 gears. Unfortunately no one is offering gears or true lockers for the Grand Cherokee.
@@srtabc123 thanks!
The only thing I like about the v6 is that it’s powerful and crazy, I love when you have your windows down then let go of the gas after acceleration you here a STUTS from the turbo
The v6 is not turbo.
It make a lot diff if you were in Tibet with average altitude above 4000m...
The V8 is not tunned for great acceleration on Grand Cherokee : I just tryed both engine (3.6 and 5.7 V8). Its really sad that the V8 is so badly tunned. So I bought a 4runner TRD offroad Premium !
