2022 Jeep Grand Cherokee 4xe First Drive Review

MOAB, Utah and AUSTIN, Texas — The Jeep Grand Cherokee rollout has taken the higher a part of a 12 months to totally notice, however with the launch of the brand new 2022 Grand Cherokee 4xe plug-in hybrid, it’s throughout however the proverbial crying. Nicely, at the very least till Jeep begins stuffing Hurricane inline-sixes below the hood. Anyone wish to place bets on that timeline?

So, the fundamentals. The Grand Cherokee 4xe’s powertrain is lifted just about immediately from the Wrangler 4xe. They make the identical energy (375 horses) and torque (470 pound-feet). “Plug-in hybrid” is a mouthful, so that you’d be forgiven for anticipating that the powertrain itself is inherently complicated, however mechanically, it’s fairly easy.

Up on the nostril, there’s a 270-hp, 2.0-liter turbocharged inline-four engine (primarily the identical one used as a standalone turbo-four within the Wrangler). Sandwiched between that and the eight-speed automated transmission is a 100-kilowatt (134 hp) electrical traction motor. This motor successfully takes the place of the transmission’s torque converter, with clutches on both facet to regulate the stream of energy.

Electrical energy is saved in a pair of batteries (17.3 kilowatt-hour complete) saddled on both facet of the Grand Cherokee’s transmission and driveshaft tunnel, which is a particular little bit of packaging. Since it is a Grand Cherokee, the 4xe system is mated to Jeep’s “Quadra Trac II” 4×4 system with its two-speed switch case. All informed, this combo is nice for barely higher EPA-certified all-electric vary than the Wrangler’s (26 miles vs. 22), a way more strong 6,000 kilos of trailer towing, and a 47.4:1 crawl ratio.

Within the hierarchy of Grand Cherokee, the 4xe appears to be like excellent on paper. It has extra energy than the 5.7-liter Hemi V8 (and will get to 60 a full second faster, Jeep says), affords an all-electric mode, will get higher mileage than the three.6-liter Pentastar do you have to not reap the benefits of that all-electric mode (23 mpg mixed vs. 22) and nonetheless does all of the Jeep issues. There’s even a Trailhawk with all of the off-road bells and whistles, and sure, you’ll be able to off-road it in pure EV mode.

That’s mighty chonky for a midsize two-row SUV, and though the 4xe is essentially the most fuel-efficient Grand Cherokee, that weight has repercussions other than the results of fundamental physics. That is an SUV, so these 500 kilos come out of the 4xe’s towing capability, which quantities to six,000 kilos. Which may be respectable for the section, nevertheless it’s 1,200 kilos (a fundamental aluminum automobile hauler, just about) lower than the Hemi can tow. Weight issues.

However let’s flip that round yet another time. Certain, added mass is normally dangerous (although not all the time, in case you imagine Porsche or Bentley), however that mass was added down low, the place Jeep’s engineers tried to pay attention the Grand Cherokee’s heart of gravity. Even within the gasoline-powered mannequin, the entrance axle shaft is routed by means of the Pentastar V6’s oil pan. That technique allowed the engine to be positioned decrease within the automobile with out compromising off-road functionality; the identical precept is at work right here. 

On the highway, the 4xe carries its further heft properly. I’ve pushed it twice now — as soon as exterior Austin, Texas, and once more round Moab, Utah. The previous was a slightly plain affair involving a variety of rural freeway driving interrupted by a short (albeit entertaining) off-road tour adopted by a run-in with a younger, formidable whitetail deer. Nearly no harm was accomplished, however the incident was illustrative of how a lot that further weight issues. Even going not more than 35 mph on a dust highway, that 4xe wanted some critical “woah” to come back down from a trot. Killer package deal, certainly.

The latter was extra informative, as Moab was additionally the venue for my non-hybrid Grand Cherokee drive late final 12 months, giving me the chance to cowl the identical floor as earlier than, solely this time with the hybrid powertrain. In Moab, the 4xe is king. Although it sits in a river valley, Moab’s elevation is above 4,000 ft. The V6 and V8 engines felt far much less spry at these heights than they do nearer to sea stage, however the 4xe’s electrical traction motor doesn’t have to ingest air as a way to make energy and its engine advantages from turbocharging, which might cram extra of that less-dense air into the combustion chamber extra effectively than a naturally aspirated induction system.

I made some extent to retrace my steps from final 12 months, however with a brand new twist — I made some extent to reset the journey pc earlier than climbing the switchbacks of La Sal Mountain Loop Highway. This was the identical stretch that prompted me to name the Pentastar V6 ample however not invigorating. The 4xe is much extra desirous to assault the uphill sections and simply reined again in when the highway pitches the opposite method. The hybrid powertrain will get some credit score right here because of its Max Regen function, which pegs the traction motor’s regenerative braking at its max resistance, permitting for a fairly first rate implementation of one-pedal driving.

Jeep’s one-pedal drive calibration maxes at 0.25 g, which is sufficient to brake even on steeper declines whenever you merely carry off the throttle, nevertheless it’ll take some time to come back to a whole cease with out assist from the friction brakes. The sweetness is that this mode does an admirable job of changing extra downhill momentum into saved electrical energy. As I end result, I averaged 29.4 mpg over the course of the 42-mile drive up and down the mountains. Regardless of clocking 26.4 miles on battery and 16.0 miles on gasoline, I nonetheless had 44% of my battery reserve (or 14 miles, the sprint estimated) once I parked the 4xe. I began the climb with far much less.

Dynamically, that low heart of gravity pays dividends. Understeer is the secret in case you begin pushing too laborious, however the 4xe’s nostril is surprisingly alert to inputs until you intentionally over-drive it. Keep in mind, the hybrid system thrives on braking and there’s no e-axle within the rear that wants time to react to your ham-fisted shenanigans. Haul it in, get it pointed someplace vaguely protected, roll assertively again on the throttle and the 4xe’s rear finish will end the job for you.

Because the Grand Cherokee’s off-road-focused Trailhawk trim is offered in 4xe guise, it needs to be no shock that Jeep wished to point out off its capabilities. All of its off-road bits made the transition from the Grand Cherokee Trailhawk V6, so you continue to get the digital sway bar disconnect, an digital limited-slip rear differential, all-terrain tires, extra Selec-Terrain drive modes, skid plates, tow hooks and an anti-glare decal on the hood. The 4xe offers up 0.4 of an inch of floor clearance (10.9 inches vs. the non-hybrid’s 11.3 inches), 2.1 levels of breakover angle and 0.2 levels of departure angle to the non-hybrids. When you’re in it deep sufficient for any of those to matter, you most likely ought to have introduced a Wrangler.

My 4×4 gas-only expertise was behind the wheel of a 3.6-liter Trailhawk, which weighs practically eight hundred kilos lower than the 4xe Trailhawk. Let that sink in — very similar to the 4xe may in mushy sand or mud. Neither was considerable for both of my treks, fortunately, and the moment torque from the 4xe’s electrical motor made its heft fade into the background — largely, anyway.

Sluggish, technical rock-crawling brings it into sharp aid. Jeep clearly firmed up the 4xe’s air suspension to assist management all that further mass, however when issues get jiggly, it’s laborious to disregard simply how a lot vehicular corpulence that system has to handle. One false transfer might deliver the 4xe’s underbelly (the place the batteries and gasoline tank dwell) down laborious on an unanticipated or unseen protrusion. Whereas that electrical motor torque could masks the 4xe’s heft from a lifeless cease, modulating it in conditions the place a big compression occasion may happen requires a bit extra finesse and forethought.

I known as the Jeep Wrangler 4xe the very best instance of the open-top 4×4, and followers of consistency might be happy to notice that the identical holds true for the Grand Cherokee. It’s not excellent, neither is it essentially the suitable Grand Cherokee for each purchaser, particularly since its base worth plus vacation spot has it knocking on the door of $60,000. A Restricted V6 4×4 can be about $10,000 cheaper, albeit with much less commonplace tools. However for many who wish to drop massive cash on an expensive midsize SUV that may enable them to kick their every day gasoline behavior with out giving up highway journey versatility, the 2022 Jeep Grand Cherokee 4xe is a killer package deal. However please, hold it figurative.
