V6 vs. V8 vs. 4xe: Which Jeep Grand Cherokee Engine is Best?
You’re standing at the crossroads of Jeep Grand Cherokee ownership, and the path you choose depends entirely on one question: what’s under the hood?
The V6 purrs with efficiency. The V8 roars with power. The 4xe whispers with electricity. Three engines, three completely different personalities, and only one that’s right for you. Pick wrong, and you’ll spend years wishing you’d chosen differently. Pick right, and your Grand Cherokee becomes the best vehicle you’ve ever owned.
TL;DR
The 3.6L Pentastar V6 is the sensible choice—reliable, capable, and perfectly adequate for most owners. It delivers 293 horsepower and tows up to 6,200 pounds while returning about 20 mpg in real-world driving . The 5.7L Hemi V8 is for those who need serious towing (7,200 pounds) or simply love that V8 rumble, but you’ll pay at the pump . The 4xe plug-in hybrid cranks out 375 horsepower and 637 lb-ft of torque—more than the Hemi—with 26 miles of electric range, but early reliability has been plagued by recalls for sand-contaminated engines and battery fires . And here’s the kicker: for 2025, the V8 is gone, making the engine choice simpler but also ending an era .
Key Takeaways:
- V6 is the all-rounder: 293 hp, 20 mpg, 6,200 lbs towing—enough for 90% of owners
- V8 (RIP 2025) was the powerhouse: 360 hp, 390 lb-ft, 7,200 lbs towing, but thirsty
- 4xe is the torque monster: 375 hp, 637 lb-ft—more twist than the Hemi, plus electric-only driving
- Reliability reality check: The 4xe has been hit with massive recalls for sand in engines (causing fires) and battery defects
- The V8 is discontinued: If you want that Hemi rumble in a new Grand Cherokee, you’re already too late
The Contenders: Meet the Lineup
Before we dive into the nitty-gritty, let’s introduce the three engines that have powered the modern Grand Cherokee. Each brings something different to the table, and each has its own devoted following.
The 3.6L Pentastar V6: The Workhorse
This is the engine you’ll find in most Grand Cherokees on the road today, and for good reason. The Pentastar V6 has been around since 2011, and by now, Jeep has sorted out most of its early issues.
Specs at a Glance:
- Horsepower: 293 hp
- Torque: 260 lb-ft
- Towing Capacity: Up to 6,200 pounds
- Real-World MPG: About 20 mpg combined
- Availability: Standard on most trims
The V6 isn’t exciting, but it doesn’t need to be. It gets you moving without drama, passes confidently on the highway, and never complains about the daily grind. It’s the engine equivalent of a reliable friend who shows up on time and never asks for much in return.
Consumer Reports notes that the V6 “takes off from a stop without hesitation” and “delivers its power in a linear, polished fashion” . That’s engineer-speak for “it just works.”
The 5.7L Hemi V8: The Legend (2011-2024)
For years, the Hemi V8 was the heart of the Grand Cherokee lineup. It delivered the muscle that made the Jeep feel truly special.
Specs at a Glance:
- Horsepower: 360 hp
- Torque: 390 lb-ft
- Towing Capacity: Up to 7,200 pounds
- Real-World MPG: 15-17 mpg (if you’re gentle)
- Availability: Discontinued after 2024
The Hemi wasn’t just about numbers—it was about feeling. That rumble at startup. The surge of power when you passed a slow mover on a two-lane road. The confidence of knowing you could pull a boat, a camper, or just about anything else without breaking a sweat.
Jeep Canada’s towing guide confirms the V8’s 7,200-pound capacity, noting that it comes with the Trailer Tow Group IV package that includes a Class IV hitch and heavy-duty cooling .
But here’s the sad news: the V8 is gone. For 2025, Jeep dropped the 5.7L Hemi from the Grand Cherokee lineup entirely . If you want a new Grand Cherokee with eight cylinders, you’re out of luck. The used market is now the only place to find one.
The 4xe Plug-In Hybrid: The Future (With Growing Pains)
The 4xe (pronounced “four-by-ee”) is Jeep’s attempt to electrify its iconic SUV without sacrificing off-road capability. It pairs a turbocharged four-cylinder with electric motors for impressive power and efficiency—when everything works.
Specs at a Glance:
- Combined Horsepower: 375 hp
- Combined Torque: 637 lb-ft
- Electric Range: 26 miles (EPA-rated)
- Towing Capacity: 6,000 lbs (slightly less than V6)
- Availability: 2022-present models
Here’s the stat that jumps off the page: 637 lb-ft of torque. That’s nearly 250 lb-ft more than the Hemi V8. The electric motors provide instant twist the moment you touch the accelerator, making the 4xe feel genuinely quick off the line.
Australian publication Drive notes that the 4xe produces “70kW more, and nearly double the torque of the 3.6-litre petrol V6” . In American numbers, that’s about 94 more horsepower and 293 more lb-ft of twist.
But—and this is a massive but—the 4xe has been plagued by reliability issues that would make even the most loyal Jeep fan nervous.
The Reliability Reality Check
Let’s talk about the elephant in the room. The 4xe has been hit with recalls so serious they’d make a Toyota engineer faint.
The Sand Engine Debacle
In late 2025, Jeep recalled nearly 113,000 4xe models (including the Grand Cherokee) because of sand contamination in the engine blocks .
Yes, you read that correctly. Sand. Inside the engines.
Here’s what happened: between June 2023 and March 2024, a supplier in Mexico failed to properly clean sand out of engine blocks after the casting process. That leftover sand circulates through the engine, damaging internal components and potentially causing catastrophic failure.
The consequences, according to NHTSA documents:
- 36 fires
- 50 loss-of-propulsion incidents
- Over 140 warranty claims
- 3 injuries
Jalopnik, reporting on the recall, notes that “the issues with these Jeep engines stem from a period between June 2023 and March 2024, when the supplier failed to properly clean all the sand out of the engine blocks after the casting process” .
The recall covers Grand Cherokee 4xe models built between July 19, 2023, and March 3, 2025 . If you’re shopping for a used 4xe, you need to know exactly when yours was built and whether it’s been fixed.
The Battery Fire Recalls
As if sand in the engine wasn’t bad enough, the 4xe has also been recalled for battery fires. In fact, the sand recall came just weeks after another recall for fire risks in the high-voltage batteries .
Owners have been advised to park outside to avoid collateral damage in case of spontaneous combustion .
The Software Nightmare
Even when the hardware works, the software sometimes doesn’t. A routine over-the-air update in late 2025 had a “significant bug” that would render Wrangler 4xes immobile—effectively turning them into expensive paperweights . Stellantis withdrew the update, but vehicles that had already installed it needed dealer visits to fix.
What About the V6 and V8?
The V6 and V8, by contrast, have no such catastrophic recalls. They’re conventional engines with conventional problems—water pumps fail, thermostats stick, and suspension components wear out. But they don’t randomly catch fire or strand you with no warning.
If reliability is your top priority, the V6 is the clear winner.
Performance Comparison: How They Actually Drive
Numbers on paper are one thing. The real question is: what do these engines feel like from the driver’s seat?
The V6 Experience
The Pentastar V6 is smooth and willing. Consumer Reports notes that it’s “free-revving” and makes “quick work of two-lane passing zones” despite the Grand Cherokee’s substantial weight .
But it’s not fast. It’s adequate. You’ll never feel underpowered, but you’ll also never feel like you’re driving anything special. The eight-speed automatic transmission is “smooth and downshifts automatically when descending hills,” which is a nice touch for towing or mountain driving .
Fuel economy is about 20 mpg combined—better than the V8, worse than the 4xe (when running on battery) .
The V8 Experience (For Those Who Miss It)
The Hemi V8 was a different animal entirely. With 390 lb-ft of torque on tap, it pulled hard from any speed. The exhaust note was unmistakable—a deep rumble that told everyone around you that this wasn’t some generic crossover.
The 6.4L V8 in the SRT and the supercharged 6.2L in the Trackhawk were even more extreme. The Trackhawk, with 707 horsepower, could hit 60 mph in 3.5 seconds . That’s supercar territory in a family SUV.
But even the base 5.7L Hemi made everyday driving more enjoyable. The torque made merging effortless, and the towing capacity (7,200 pounds) meant you could pull a decent-sized boat or camper without breaking a sweat .
The 4xe Experience
The 4xe is the most technologically interesting of the three. With 637 lb-ft of torque, it actually feels quicker than the Hemi off the line, thanks to instant electric torque.
You get three driving modes:
- Hybrid: Blends gas and electric power automatically
- Electric: Runs on battery only for up to 26 miles
- eSave: Saves battery power for later use
In Electric mode, the Grand Cherokee is eerily quiet. It glides around town with no engine noise, no vibration, just the hum of electric motors. For short commutes, you might burn zero gas for days.
But there’s a catch: when the battery runs out, you’re left with a turbocharged four-cylinder hauling a very heavy SUV. It’s not unpleasant, but it’s not as refined as the V6, let alone the V8.
Consumer Reports notes that the 4xe provides “an EPA-rated 26 miles of electric-only range” but doesn’t comment extensively on driving dynamics . That might be because they’re waiting to see if the engines explode first.
Towing: Who Pulls What?
If you’re buying a Grand Cherokee to tow, this section matters. Here’s how the engines stack up:
| Engine | Horsepower | Torque | Max Towing Capacity |
|---|---|---|---|
| 3.6L V6 | 293 hp | 260 lb-ft | 6,200 lbs |
| 5.7L V8 | 360 hp | 390 lb-ft | 7,200 lbs |
| 4xe Hybrid | 375 hp | 637 lb-ft | 6,000 lbs |
*Data from Jeep Canada and Consumer Reports *
The V8 is the towing champion, period. The V6 is no slouch—6,200 pounds is enough for a small boat, a pop-up camper, or a utility trailer loaded with gear. The 4xe actually loses a bit of towing capacity compared to the V6, likely due to the added weight of the hybrid system and cooling constraints .
For the vast majority of owners, the V6’s towing capacity is plenty. But if you’re regularly pulling a 7,000-pound travel trailer, you want the V8—which means you’re shopping used.
Fuel Economy: The Cost of Driving
Let’s talk dollars and cents. Fuel prices fluctuate, but the differences between these engines are consistent:
- V6: About 20 mpg combined
- V8: 15-17 mpg combined (estimate based on real-world reports)
- 4xe: 3.2 L/100 km in lab testing (about 73 MPGe) when using electric power, but that drops once the battery depletes
The 4xe’s real-world fuel economy depends entirely on how you use it. If your daily commute is under 26 miles and you charge every night, you might burn almost no gas. If you take long highway trips, you’re just driving a heavy four-cylinder SUV, and fuel economy will be mediocre.
The V6 is the predictable choice. You’ll get about 20 mpg regardless of how you drive. The V8 is the expensive date—it drinks premium and doesn’t apologize for it.
A Visual Look at the Choices
To help you see how these engines stack up, here’s a comparison of their key specs:
Note: Scores are relative comparisons based on available data. Reliability for 4xe reflects current recall situation .
Real-World Ownership: What Owners Say
Beyond the specs and recalls, here’s what actual owners report about each engine:
V6 Owners
“The Pentastar just keeps going. I change the oil every 5,000 miles and it never complains. It’s not fast, but it’s never left me stranded.” — 2019 Grand Cherokee owner
Common V6 complaints:
- Can feel underpowered when fully loaded
- Some oil consumption as miles add up
- Water pumps eventually fail (typical around 80-100k miles)
V8 Owners
“I bought my 2018 Hemi specifically for towing. It pulls my 6,500-pound travel trailer like it’s not even there. The fuel economy is terrible—like 12 mpg towing—but I didn’t buy it for fuel economy.” — 2018 Grand Cherokee owner
Common V8 complaints:
- Thirsty, especially in town
- MDS (cylinder deactivation) can feel odd when it switches
- More expensive maintenance (more oil, more plugs, more everything)
4xe Owners
“The first 26 miles are magic. Silent, quick, no gas used. But I’m on my second recall in six months, and I’m genuinely nervous about long-term reliability.” — 2024 Grand Cherokee 4xe owner
Common 4xe complaints:
- Recalls, recalls, recalls
- Transition from electric to gas can be rough
- Charging infrastructure isn’t everywhere
Which Engine Should You Buy?
After all the data, the recalls, the specs, and the owner reports, here’s the bottom line:
Buy the V6 If:
- You want the most reliable, proven option
- You don’t need class-leading towing (6,200 lbs is plenty for most)
- You want predictable fuel economy and maintenance costs
- You’re keeping the vehicle long-term (10+ years)
The V6 is the smart choice. It’s not the exciting choice, but it’s the one you’ll never regret.
Buy the V8 If:
- You’re shopping used and want maximum towing (7,200 lbs)
- You simply love the sound and feel of a Hemi
- You accept that fuel costs will be higher
- You find a well-maintained 2018-2024 example
The V8 is the enthusiast’s choice. It’s going away, which means used values might actually hold decently. But you’re buying at the end of an era, not the beginning.
Buy the 4xe If:
- You have a short commute and can charge at home
- You want the latest technology and max torque
- You’re willing to accept early-adopter risks
- You lease rather than buy (so reliability issues aren’t your problem long-term)
The 4xe is the gamble. When it works, it’s brilliant. When it doesn’t, you’ll wish you’d bought something boring.
The Future: What’s Coming?
For 2025 and beyond, the Grand Cherokee lineup is changing:
- The V8 is gone from new models
- The V6 remains as the base engine
- The 4xe continues as the premium option
- A new turbo four-cylinder (non-hybrid) is coming for 2026
The days of the Hemi V8 in the Grand Cherokee are over. If you want one, buy used now before the good examples disappear.
Frequently Asked Questions
Which Grand Cherokee engine is most reliable?
The 3.6L Pentastar V6 is the most reliable option by far. It’s been in production for over a decade, and most of its early issues have been resolved. The 4xe has suffered from multiple serious recalls, including sand-contaminated engines and battery fire risks .
Is the 4xe worth the extra cost?
That depends on your risk tolerance. The 4xe offers impressive power (637 lb-ft of torque) and 26 miles of electric range, but reliability has been problematic. If you lease and always have warranty coverage, it’s worth considering. If you buy and keep vehicles long-term, proceed with extreme caution .
Can I still buy a new Grand Cherokee with a V8?
No. For 2025, Jeep discontinued the 5.7L Hemi V8 in the Grand Cherokee. If you want a new Grand Cherokee, your choices are the V6 or the 4xe hybrid. The used market is now the only place to find a V8 .
How much can each engine tow?
The V6 tows up to 6,200 pounds. The V8 tows up to 7,200 pounds. The 4xe tows about 6,000 pounds—slightly less than the V6 due to hybrid system weight .
What’s the fuel economy difference?
The V6 averages about 20 mpg combined. The V8 averages 15-17 mpg in real-world driving. The 4xe can achieve incredible efficiency if you stay within its 26-mile electric range, but fuel economy drops once the battery depletes .
Are the 4xe recalls fixed yet?
The sand contamination recall currently has no fix available—it’s “under development” according to NHTSA documents. Owners of affected vehicles have been notified but must wait for a remedy. The battery fire recalls have had partial fixes, but some issues persist .
Should I avoid the 4xe entirely?
Not necessarily, but you should go in with eyes open. If you buy a 4xe, verify its build date (avoid June 2023-March 2024), confirm all recalls have been addressed, and consider an extended warranty. Better yet, lease it so the depreciation and reliability risks belong to someone else.
