MG Im5 vs Jeep Gladiator

What's the difference?

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.

The Jeep Gladiator Rubicon is a very capable off-roader and it's not as terrible on-road as some people might assume.

But while it's a whole lot of fun to steer around on the dirt, it lacks the versatility, safety tech, and refinement that would shift it from simply being a decent hard-core 4WD ute to a good general-purpose vehicle.

However, by focussing on those factors, you're in danger of missing the Gladiator's point entirely. This is a purpose-built 4WD fun machine, which is perfect for its intended use. But, the problem is, it's not perfect, or even very good, at anything else.

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.

The Jeep Gladiator appears built for purpose if your purpose is to head bush and have fun. And in Rubicon form it sure looks like it's capable of tackling hard-core 4WDing.

The Gladiator looks very much like its stablemate, the iconic Wrangler, with its chunky front end and blocky body.

It has more than the inkling of a US-style pick-up's presence at 5591mm long (with a 3488mm-long wheelbase), 1894mm wide, 1909mm high, and with a kerb weight of 2242kg.

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. 

You have to give Jeep's designers credit because they know their outdoorsy stuff. The Gladiator's interior is nothing if not practical.

The ute has a squared-off and action-ready interior that seems up to the task of copping the dirt of an outdoors life.

The cabin feels like it's water- and weather-proof, even if that may not literally be the case. 

It's a snug interior and build quality generally feels solid.

The 8.4-inch multimedia touch screen is clear and easy enough to read while on the go, but it's too small. The Jeep's 'Uconnect' system is simple enough to get your head around and Apple CarPlay and Android Auto are easy to get working.

There's also a 7.0-inch LED driver-information display, which shows tyre pressure, tyre-fill alert, digital speed readout and more.

All controls, dials and switchgear are chunky, making for easy operation, no matter how bumpy the terrain you're traversing is.

The reach-and-rake-adjustable steering wheel incorporates audio, voice and cruise control controls.

Storage spaces are few, but at least they're well suited to adventure, such as tensioned mesh pockets on the doors and seat backs and small spaces with textured bases for your bits and pieces.

There are two USB-A ports and a USB-C port up front and two for back-seat passengers. There's also a 230V outlet up front on the centre console.

Seating is decent all-around but anyone taller than Tom Cruise's stunt double has to mind their head so they don't thump it on the unforgivingly hard ceiling of the detachable top.

There's a shallow storage space under the rear seat and, when that 60/40 split rear seat is folded flat, there are LED lights behind to illuminate the narrow storage space in the rear of the cabin, where there are also storage nets.

The tub's load space is 1442mm wide – 1137mm between the wheel arches so not wide enough for a pallet – and it is 1531mm long. Load height is 885mm at the tailgate.

The tray has integrated tie-down points and under-rail LED lights.

Payload is now a claimed 693kg, which is better than its previous 680kg but still rather ordinary when compared to a lot of dual-cab utes available in Australia.

Gross vehicle mass and gross combined mass are listed as 2935kg and 5656kg, respectively.

The Gladiator has a maximum towing capacity of 750kg (unbraked), and its 2721kg braked towing figure is a let-down against the 3500kg capacity of most other rivals.

This is a ute better suited to weekend camping trips than load-lugging work duties.

Another bonus for tourers though: the spare wheel is a full-size steel one.

The 2023 Jeep Gladiator Rubicon has an official list price of $87,250, excluding on-road costs.

This variant's more notable standard features include Jeep's 'Rock-Trac Active On-Demand II' 4x4 system (4:1 transfer case), 'Tru-Lok' front and rear locking differentials, sway-bar disconnect, Tenneco 2.0-inch diameter aluminium-bodied shocks (front and rear; Fox shocks on previous versions), a 'TrailCam' off-road camera, selectable tyre-fill alert, BFGoodrich Mud Terrain tyres (255/75 R17), and 17-inch machined-black alloy wheels.

It also has an 8.4-inch touchscreen multimedia system (with navigation, Apple CarPlay and Android Auto), as well as LED headlights/tail-lights/daytime running lights/fog lights, forward collision warning, plus adaptive cruise control, blind-spot monitor with rear cross-path detection, remote proximity keyless entry and a nine-speaker Alpine Premium audio system.

Gladiator paint choices include standard black and 'Bright White', as well as $895 premium paint options including 'Sarge Green', 'Silver Zynith', 'Firecracker Red', 'Sting Grey', 'Hydro Blue', 'Granite Crystal' and 'High Velocity' (yellow/green).

The accessories range for the Gladiator is a line-up of more than 70 bits of gear, and includes everything from Jeep windscreen sunshades to a cargo bed storage system (drawers).

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.

The Gladiator Rubicon has the Wrangler's 3.6-litre Pentastar V6 petrol engine (209kW at 6400rpm and 347Nm at 4100rpm) and eight-speed automatic transmission.

The V6 has a lot of punch for on- and off-road driving and plenty of low-end torque for low-range 4WDing and, matched with the eight-speed auto, it's a well-proven team-up that consistently works well.

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. 

The Gladiator Rubicon has listed fuel consumption of 12.4L/100km on a combined cycle. 

On test I recorded actual fuel consumption of 12.9L/100km, from fill to fill.

The Gladiator has an 83-litre tank, so, going by my on-test fuel-use figure, you could reasonably expect a driving range of approximately 643km from a full tank.

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.

It's certainly an experience, but the Gladiator is not as atrocious on-road as you may assume.

This vehicle is a lot of fun to drive because it demands a lot of attention and input to keep it on target.

The steering is floaty, with plenty of play in the wheel and understeer through corners, and there's a fair bit of tyre rumble from the BFG muddies.

The wing mirrors generate noticeable wind noise, but the Gladiator's not as awkward or unrefined as you might expect.

Because it's essentially a stretched Wrangler – with a 787mm longer body and a 480mm longer wheelbase than its stablemate – the Gladiator has a solid stance on the road and, for such an unashamedly off-road-oriented vehicle, it feels even more settled and composed than the Wrangler does on sealed surfaces.

This 2242kg ute is built for tough fun with a body-on-frame design and reinforced chassis, but the Gladiator manages to be nimble around town.

Ride quality is generally impressive with this ute cruising comfortably on live axles front and rear with coil springs and, in 2023 onward versions, Tenneco shocks all-around rather than the previous Fox Shocks set-up.

Aspects of the Gladiator experience will annoy some people. Visibility is compromised in all directions, the throttle is touchy, the 13.6m turning circle may add a degree of difficulty in attempts at fast turnarounds (on a city street or in a busy country pub car park) and all that driver attention and input the Gladiator demands of its steerer will become tiresome for a few drivers.

But, as expected, the Gladiator's true spirit is only ever fully revealed when you head off-road. It's a hell of a lot of fun in the dirt. Drop tyre pressures, do up your seat belt and let the Gladiator off the leash.

The 'Trail Rated' Gladiator is loaded with off-road mechanicals, from a 4X4 system with 4:1 low-range (contributing to a 77.2:1 crawl ratio), front and rear diff-locks, heavy-duty Dana 44 axles (front and rear), sway-bar disconnect and BFGoodrich Mud Terrain tyres, as well as a stack of driver-assist tech aimed at making you feel like Australian 4WD expedition legend Ron Moon.

Shocks engineered for off-roading add a welcome dimension of comfort and handling to the Gladiator on fast dirt and gravel tracks on the way to your chosen off-roading destination.

That 77.2:1 crawl ratio means nothing to most of us until you have the opportunity to experience the feeling of all that terrain-gripping torque for yourself.

In 4WD low-range first gear, and with both diffs locked, the Gladiator feels unstoppable. It climbed with ease a short steep rocky hill where I've seen drivers of modified vehicles opt for the ‘chicken' tracks either side.

The only thing is, because of the Gladiator's 3488mm-long wheelbase and 18.4-degree ramp-over angle, there's a real risk of bellying out or at least grinding the undercarriage on earth when you crest these steep hills, which is why you must drive with concentrated focus.

But that's part of the fun. It really is a driver-direct experience. You need to be aware of everything that's going on, you never feel like you're one step removed from the situation, or the terrain or the consequences of your driving… you feel dialled into the terrain and that's guaranteed to put a smile on any 4WD enthusiast's face.

Besides, the Gladiator does have substantial underbody skid-plates, protecting the fuel tank, transmission and transfer case, as well as heavy-gauge tubular steel rock rails to soak up off-road hits.

With an approach angle of 40.7 degrees, a departure angle of 25.1 degrees and a listed ground clearance of 249mm and a wading depth of 760mm, the Gladiator has decent off-road measures.

Suspension travel is okay, but to get even more stretch, you can hit the sway-bar disconnect button to drop a wheel to the dirt – or as close as possible depending on how deep the ruts are.
 
The Gladiator has 'Selec-Speed Control' (effectively an adjustable low-speed cruise control for 4WDing that can be set between 1.0-8.0km/h), and 'Off-Road+', which tweaks throttle and traction control, among other systems, to best suit the terrain.

It also has a forward-facing off-road camera so the driver has a chance to see any obstacles that might otherwise go unnoticed until it's too late, such as branches, rocks, tree stumps and hard rubbish.

The Gladiator has a three-star ANCAP safety rating from testing in 2019.

Its safety gear includes four airbags, full-speed forward collision warning plus, reversing camera, adaptive cruise control, blind-spot monitoring, rear cross-path detection, tyre-pressure monitoring system, and more.

It also has hill start assist, hill descent control, and trailer sway control.

It has dual ISOFIX child seat anchor points and three top-tether attachments in the rear seat.

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.

The Gladiator has Jeep's five-year/100,000km factory warranty, five-year capped price scheduled servicing, and lifetime roadside assistance.

The first five services are capped at $399 each and scheduled servicing is due every 12 months or 12,000 km, whichever comes first.
