Jeep Grand Cherokee L vs MG Im6

What's the difference?

Jeep’s aim with this car is to lift the Grand Cherkee to a more premium level, and that’s about brand equity and badge credibility as much as it is the vehicle itself.

The seven-seat L has stepped up in price, but also in practicality, refinement and equipment, while maintaining serious off-road ability.

Does it have what it takes to tempt people away from, say, the German Big Three? That’s a tough ask, but this Jeep certainly has more of what it takes to make that a real possibility. 

For mine, the entry-level Night Eagle is the pick. Well equipped, heaps of safety and plenty of off-highway prowess.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

A decade. That’s how long the previous Grand Cherokee was on sale in Australia, Which is ages, but also testament to the quality of that fourth-generation car’s design.

And there are echoes of it in this new model’s exterior. The overall proportions are similar, although the track is increased by 36mm, and the overriding impression is that key elements have been made slimmer and wider for a more contemporary look.

For example, the headlights, LED on all models, are shorter, but longer, while the signature seven-bar Jeep grille has been truncated a little and stands more upright.

Character lines along the side of the car are softer, and the rear follows the same slimline philosophy. But it’s inside where the biggest steps have been taken.

The dash layout and hardware have been transported from the relative Dark Ages to a clean and simple approach dominated by this broad centre console, topped by a sleek media screen.

The screen measures 8.4 inches in the entry-level Night Eagle, stepping up to 10.25 inches in the upper grades.

The latest, configurable, digital instrument cluster enhances the low-key tech vibe, and there’s a sensible mix of on-screen controls and physical dials and buttons. That said, there are a lot of buttons across the lower part of the centre stack and steering wheel.

The rest of the interior is a blend of simple lines and a subtle colour palette, including piano black highlights. It feels more mature and premium than the car it replaces.

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

When it comes to practicality, thoughtful, family-friendly touches include large door apertures, with the doors themselves opening right out to 64 degrees, as well a second row seat able to move fore and aft to balance passenger and/or cargo space. 

Up front there are big bins in the doors with space for large bottles, a pair of decent size cupholders in the centre console, a two-tiered storage box between the seats that doubles as an armrest, and a covered wireless charging bay in front of the gearshift.

For connectivity and power there are two USB-A and two USB-C ports, as well as an ‘aux in’ socket, and a 12-volt outlet.

Jump into the second row, and sitting behind the driver’s seat set for my 183cm position, I enjoyed heaps of headroom and hectares of legroom, remembering it’s possible to slide the middle seat forward to give third row passenger more room, or increase load space.

Again, there are generous pockets in the doors with space for large bottles, map pockets on the front seatbacks, a fold-down centre armrest containing two cupholders, and rear seaters have their own ventilation control.

The dual USB-A and USB-C ports are repeated in the back, and there’s a 230-volt AC socket for three-pin plugs.

Access to the third row is helped by a roll and fold function in the second row, and once back there space is generous and the amenities are civilised.

I could sit bolt upright without any head clearance issues, and legroom is good. There are bottle holders on each side, adjustable ventilation in the C-pillars, small storage pockets, and yet more USB outlets. 

And how’s this for a parent’s dream? ‘Fam Cam’ (optional on the Limited and standard on the Summit Reserve) is an adjustable rear seat monitoring camera able to switch between all second and third row positions. No more craning around and taking your eyes off the road to check what’s going on back there.

Even with all seven seats upright, boot space is 487 litres. Fold the 50/50 split third row and that grows to 1328L, and with the second (40/20/40 split) and third rows down you’ve got 2395L, enough room to start a boutique furniture moving business.

The loading height is user friendly, there are multiple tie-down hooks and a 12V outlet, there’s no lip to get over the top of, and a power tailgate, standard on all grades and hands-free on the Summit Reserve, is always welcome.

The Grand Cherokee L is rated to tow a braked trailer up to 2.8 tonnes, although that’s reduced to 2.3 tonnes in the Summit Reserve, partly due to the standard air suspension. And off-roaders rejoice, the spare is a full-size (18-inch) steel rim. 

The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.

There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990

The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.

Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.

There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.

There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.

Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.

Honestly, it’s a lot of stuff, and a lot of tech.

All versions of the Grand Cherokee L are powered by a 3.6-litre naturally-aspirated V6 petrol engine producing 210kW at 6400rpm, and 344Nm at 4000rpm, driving all four wheels through an eight-speed auto transmission and a transfer case - single speed on the first two models and two-speed on the Summit Reserve flagship.

The evergreen Pentastar V6 is a naturally-aspirated, all-alloy, quad-cam design featuring dual variable valve timing and sequential-injection.  

If you want more grunt? Yes, there’s a 5.7-litre Hemi V8 available in this new Grand Cherokee. But it’s in the States, not here. There’s no diesel option, either. But as mentioned earlier, a plug-in hybrid, the 4xe (four-by-e) is coming later in 2022. 

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

Jeep’s official fuel economy figure for the Grand Cherokee L on the combined cycle is 10.6L/100km, the 3.6-litre V6 emitting 243g/100km of CO2 in the process.

Given the specific on and off-road combination of the launch drive we’ll wait until we can evaluate the car over a longer period to quote an ‘on test’ number.

Worth noting stop-start is standard, and in the name of weight saving, the car’s bonnet and tailgate are aluminium. Still weighs around 2.2 tonnes, though.

The tank holds 104 litres, which using the quoted consumption number, translates to a range of around 980km.

Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.

Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.

In driving the new Grand Cherokee the first thing you recognise is the Pentastar V6’s characteristic induction sound. That’s not to say it’s overly loud, just familiar.

But in terms of what it delivers, nearly 90 percent of the engine's peak torque is available from 1800 to 6400 rpm, so you’ve got that mid-range pulling power which is as nice on the highway as it is around town, but also good for people that are into towing.

The eight-speed auto is nice and smooth, as well, and even though it’s a conventional torque-converter unit, manual shifts through the steering wheel paddles are quick.

Suspension is multi-link front and rear, with the top-spec Summit Reserve picking up air suspension and active damping. Major components are alloy to reduce unsprung weight but you can certainly feel the scale of this car. 

It’s 5.2 metres long and weighs roughly 2.2 tonnes, so you’re guiding this sizeable machine along the road. It’s not an involving drive, we’re not in sports car territory here. But it feels stable and predictable in cornering, and body control is well buttoned-down.

The electrically-assisted steering’s weight is nice from parking speeds right up to freeway velocity, but road feel through the wheel is relatively modest.

In terms of the seating position, you do feel as though you’re sitting up and on, rather than down and in the front seats. But when it comes to support, after hours behind the wheel, including off road, the front chairs remained comfortable.

This is a big vehicle, that will often have a boat, van, or something else substantial hitched to the back of it, and the brakes are suitably specified.

Big discs are ventilated all around, clamped by two piston calipers at the front and singles at the rear, and on the off-road section of the launch drive we were by necessity leaning on the brakes for long periods of time.

You could occasionally smell that they were working hard, but the pedal remained firm all day, without a hint of fade.

Speaking of off-highway performance, as part of its development program Jeep tested this new Grand Cherokee in remote parts of Australia, with more than 60,000 km under the wheels of various prototypes. Likely a big help in setting up the local spec. 

And that spec is, four-wheel drive in all models, as well as a single-speed transfer case in the Night Eagle and Limited, with the latter also featuring the ‘Selec-Terrain’ traction management system, controlling torque split (up to 100 per cent of drive to either axle), as well as the brake calibration, steering, suspension, throttle, transmission, transfer case, traction control, stability control, and ABS settings.

The Summit Reserve boasts a two-speed transfer case, with low-range reduction, as well as traction management and air suspension with electronic adaptive damping.

The air suspension incorporates five height settings - Normal, Off-road 1 (40mm lift), Off-road 2 (60mm lift), Park (46mm lower), and when in sport, Aero (21mm lower).

In typical Jeep fashion we attacked challenging fire and forestry trails on the launch drive and a couple of things emerged.

First, on street-focused tyres this car does incredibly well off-highway. And second, the ‘Quadra-Trac II’ 4x4 system with low-range capability in the Summit Reserve, combined with the crawl control function, makes a significant difference. You find yourself feeling that bit more composed and confident tackling very rough sections.

Also in the Summit Reserve, a low-set, forward facing camera allows you to see what’s actually happening at the front wheel via the central media screen, and in the Off-road 2 setting the car feels like it’s up on stilts and able to tackle anything in its way.

And for those that really want to get amongst it, the body clearance data is below.

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.

As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.

The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.

Jeep covers the Grand Cherokee with a five-year/100,000km warranty, which is behind the five-year unlimited kays cover which is pretty much standard in the mainstream market now.

But you do receive 12 months complimentary roadside assistance, which is renewed for another year every time you service your vehicle at an authorised Jeep dealer.

Service is recommended every 12 months or 12,000km, and capped price servicing is available for $399 annually for the first five years. Not bad for a car of this scale and complexity.

The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
