Jeep Grand Cherokee L vs MG Im5

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.

The MG IM5 Performance is fast, comfortable, quiet and super refined. Putting some minor spec and active safety niggles to one side, it offers the features, tech and price to match it with its well-credentialled and already popular mid-size EV sedan competitors. Is there room for one more? We think there should be.

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.

Playing spot the straight line on the outside of the MG IM5 is like an automotive design version of Where’s Wally? There aren’t many, in the midst of an unrelentingly curvaceous exterior treatment.

At close to five metres long and two metres wide the IM5 is appreciably longer (+211mm), a little wider (+27mm) and a bit taller (+33mm) than a Tesla Model 3. Think BMW 5 Series in terms of overall size.

And the soft-form shape is functional; the swoopy liftback boasting an ultra-slick 0.24 drag coefficient.

That said, I’m not convinced by the ‘Periscopic’ cameras informing the driver assistance systems from the front guards. They scream tacked-on afterthought. But a touch-only initial opening function for the flush door handles is cool and makes life easier.

The curves continue inside with soft-padded surfaces around the dash and doors, but the straight edge obviously came out for the 10.5-inch central media screen and vast 26.3-inch upper display. There are next to no buttons; even exterior mirror adjustment is directed from the screen to a multi-function steering wheel control.

System software (powered by a Qualcomm ‘Snapdragon’ chip) is lightning fast with a two-finger up and down swipe shortcut function on the central screen for ventilation and other functions.

The interior is light and bright thanks to the enormous panoramic sunroof. It’s been fine in cooler winter conditions during this test but it could be interesting to revisit in the heat of an Aussie summer

There are two interior colour schemes available - the ‘Highland Grey’ of our test car or ‘Dover Beige’ for those brave enough to live life with the threat of scuff marks on your shiny new car’s glamorous but vulnerably light interior.

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. 

There’s plenty of breathing room up front and in terms of storage one of the first things worth calling out are the long but relatively narrow door bins. No good for anything above unusually slender bottles, even if they’re lying down.

No conventional glove box in the dash, but there is a large lidded box (cooled and heated) between the seats that doubles as a centre armrest. It’s supplemented by a big stowage area underneath the flying buttress style centre console.  

There are two cupholders in the centre console as well as a wireless device charging pad in front of them with a vaguely phone-shaped oddments bin alongside it.  

Move to the rear and the IM5’s 75mm wheelbase advantage over the Tesla Model 3 is clear. Heaps of knee and headroom for me at 183cm sitting behind the driver’s seat set to my position. 

But… the seat sits low which pushes your knees up into the air to the point where my thighs are not contacting the seat cushion. Even though the rear seat reclines to a certain degree it’s a problem compounded by a chronic lack of room for your toes under the front seat. Awkward.

There are map pockets in the front seatbacks, modest bins in the doors and a fold-down centre armrest with two cupholders. Adjustable ventilation in the rear of the front centre console always makes life in the rear seat more pleasant.

The car also houses ‘Strong Magnets’ at various points around the cabin and boot, with a configurable adapter able to lock a phone or tablet into place for the entertainment of, in our case, back seaters. 

Speaking of devices for entertainment, there are two USB-C sockets and a 12-volt outlet in the front and another USB-C and 12V in the back, so charging isn’t an issue. 

The IM5 is a liftback so the boot aperture is generous and a capacity of 457 litres with the rear seats up is decent for a car of this size, although that’s less than the Tesla Model 3 (594L) which has an additional well under the floor. 

Still, enough room for the largest (124L) and smallest (36L) suitcases from the CarsGuide three-piece luggage set with some room to spare.

The power tailgate can be operated hands-free via the key or an always welcome under bumper kick function.

Volume expands to 1290 litres with the rear seats folded and there’s a modest 18-litre ‘frunk’ under the bonnet.

The bad news is a repair-inflator kit rather than a physical spare wheel, but the better news is the IM5 Performance can tow a 1500kg braked trailer (750kg unbraked).

The IM range also features the ‘MG iSmart’ app allowing remote control of various functions including charging, checking vehicle location and route planning. 

At $80,990, drive-away, the IM5 Performance sits at the top of a three-grade line-up that starts with a 75kWh RWD Premium model at $60,990, followed by a mid-spec 100kWh RWD Platinum for $69,990, both drive-away.

Its most prominent competitor is arguably the Tesla Model 3 Dual Motor AWD ($80,900), with others including the BYD Seal Performance AWD ($68,798), Hyundai Ioniq 6 AWD Epiq ($86,500) and Polestar 2 Long Range Dual Motor Performance ($80,380).

Worth noting, too, the IM6 range - essentially the same car with a taller SUV body - has the same model walk-up and identical pricing.

Once you’ve crossed the $80K threshold it’s fair to expect a decent basket of standard fruit and aside from the dynamic and safety features we’ll get to shortly, the IM5 Performance comes to the party.

Highlights include a double-glazed panoramic roof, power-adjustable (12-way driver, six-way passenger) heated and ventilated front seats (also heated in the rear), dual-zone climate control, 20-speaker audio (with digital radio), 256 colour ambient lighting, a power tailgate (with hands-free function) and 20-inch alloy rims.

There’s also adaptive cruise control, a heated steering wheel, wireless Android Auto and Apple CarPlay, LED headlights, keyless entry and start, wireless device charging (50W), a 10.5-inch central control screen and a sweeping 26.3-inch upper screen; the right side for instrumentation and car data, the (touch-sensitive) left side for multimedia and other onboard functions.

There’s more and it’s clear this car at least matches or betters its direct competitors for included equipment.

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. 

The MG IM5 Performance is powered by an electric motor on each axle - the rear (372kW/500Nm) more powerful than the front (200kW/300Nm), for overall outputs of 572kW (that’s close to 770hp) and 802Nm of pulling power.

The official term for that amount of grunt is… a lot. And we’ll get to what it means on the road in the Driving section shortly.

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.

The MG IM5 Performance features an 800-volt electrical architecture which means the 100kWh NCM battery can accept a DC peak charge of close to 400kW.

Only snag is the highest you’ll currently find in Australia is 350kW. But even at that rate you’ll still be looking at a 30-80 per cent charge in just over 15 minutes. Maximum AC charge rate is 11kW.

Claimed range is 575km (WLTP) which is less than the Tesla Model 3 Dual Motor AWD at 629km.

Over a week of city, suburban and some freeway running we saw average energy use of 20.6kWh/100km which is on the high side for an EV of this size but maybe not for one with this kind of performance potential. 

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, the IM5 Performance is supercar fast. This 2.3-tonne five-seater blazes from 0-100km/h 3.2 seconds and with its dual motors combining to produce 572kW/802Nm, eye-widening performance always resides underneath your right foot.

But it’s not all about straight line speed. Ride comfort is excellent. Underpinned by an all-new platform, the IM5’s suspension is by double wishbones at the front and multi-links at the rear. But the key to its bump and rut smoothing ability is air suspension and ‘continuous control’ active damping.

Fold in double-glazing on the full-length glass roof and side windows, as well as active noise cancellation and you have a serene interior environment at any speed. Also worth noting the front seats are great; as grippy as they are comfortable.

Not only that, despite its relative heft, this mid-sizer steers well, too. Not the last word in road feel but it points accurately and the standard rear steering helps with prompt (but never jerky) cornering turn-in. Flick to ‘Sport’ mode and the IM5 is up for some enthusiastic running.

The rear wheels can turn up to 12 degrees in the opposite direction to the fronts at slow speed, which makes for a usefully tight 10-metre turning circle. But above that, at lesser angles, it adds extra stability and decisiveness in the way the car steers through even tight, twisty sections.

Rubber is top-shelf Pirelli P Zeros on 20-inch alloys (245/40 fr - 275/35 rr) and it grips hard, especially in the wet weather over much of the test period. Braking is solid, as it needs to be, with ventilated discs all around and four-piston callipers at the front. 

No adjustable regen braking but you can feel the ‘Cooperative Regenerative Brake System’ (CRBS) doing its thing when you lift off the accelerator. 

The physical rear view is modest thanks to the slope of the back window reducing its functional area for the driver to that of a 1950s VW Beetle. Even the interior rear-view mirror is tiny and folds up into a recess in the headliner if you’d prefer life without it.

But that’s where a rear camera view popping up on the upper screen display (accessed via the right-hand steering wheel click control) comes in handy. Side camera views are also available as is a 360-degree overhead view, which makes parking straightforward.

If you need more parking help there are various self-parking modes including a nifty ‘Curbside’ function that will realign the car hands-free if you’re parallel parked too far out from the kerb.

In a similar vein, a ‘Rainy Night’ mode projects left and right rear views onto the main screen using AI to enhance clarity and highlight pedestrians and cars.

Overall the ADAS (Advanced Driver Assistance Systems) are relatively unobtrusive but we found ourselves switching off the incessant overspeed chime that sounds for 10 seconds if you creep over the indicated speed limit, even when the system has misfired on the correct speed. For example, 40km/h school zones on a Sunday.

The over-zealous driver distraction warning also occasionally issued a visual and audible slap on the wrist when I was looking straight ahead. Tellingly, there’s a specific quick screen for turning both these functions off, but it kinda defeats the purpose of having them in the first place.

We also found the adaptive cruise control to be hesitant in multi-lane environments, reducing speed occasionally because the system seemingly believed a car was set to merge, when it wasn’t.

No independent ANCAP safety assessment at this point but there’s a full suite of active safety tech onboard including AEB, lane departure warning, blind spot detection, rear cross-traffic alert & braking, forward collision warning, lane-change assist, tyre pressure monitoring and heaps more. And we touch on how it all operates in the Driving section above.

There are no less than nine HD cameras, 12 ultrasonic sensors and three millimetre-wave radars on duty.

If a crash is unavoidable there are seven airbags including full-length side curtains and a front centre bag. Multi-collision brake also minimises the chances of subsequent impacts after an initial crash. There are also three top tether points and three ISOFIX child seats anchors across the second row.

All right on the pace for this part of the market and the IM5’s competitive set.

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 MG IM5 Performance is covered by a seven-year/unlimited km warranty, which is a plus, but the catch is it’s conditional on authorised dealer servicing. Go elsewhere and the term drops to a more common five years/unlimited km. The drive battery is covered for eight years/160,000km, which is the norm in the Aussie market

Servicing is required every 12 months or 20,000km with charges averaging $586 per workshop visit for the first five years, which is on the high side for an EV, even at this price point, the average bumped up by a more than $1400 doozy at year four.

MG IM models are sold (with service available) through all of MG’s 100-plus dealerships across the country, so no concerns there.
