MG Im5 vs Subaru Forester

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.

To many people, this review won’t matter. There’s a large part of Subaru’s customer base that come back knowing they’ll get a practical, capable car regardless of refinement - something the brand’s rivals can’t quite match.

But even those people will be pleased to find the new Forester is a huge step-up over the last one in many areas. Sure, it’s a little late for Subaru to be joining the hybrid game in 2025, but it’s not the only brand from Japan that’s been slow on that front, and the brand’s philosophy hasn’t always been focused on efficiency anyway.

In a vacuum, the new Forester is a great adventure companion, but anyone considering a mid-size family SUV and not requiring the AWD and clearance the Forester has on offer could do better elsewhere.

For anyone else, there’s still only one option that really ticks all the boxes - and now it’s much better than before.

Just get the petrol if you’re going anywhere that could damage a tyre.

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 new Forester is a slight departure from the characterful previous generation, and to this writer’s eye that’s to its detriment. It’s not unpleasant to look at, but it doesn’t look so much like a Forester anymore.

I wouldn’t be the first to say it looks like it had at least one pass through the North American Ford design centre, but even putting that aside, the rounded front is a less interesting design treatment than we’re used to seeing from Subaru.

Its side profile shows off its boxy, practical nature, however, and from the rear it looks much more Subaru-like than from the front.

In Sport guise, particularly, the Forester’s bronze trim and wheels are a decent give-away that the brand was going for a more premium look.

Inside, the Forester doesn’t look enormously different from the last generation, especially when it comes to buttons, shifters, and the big vertical 11.6-inch touchscreen, the latter right out of other Subaru models that have been around a while.

But perhaps that was deliberate, because some of the new Forester’s best features are those that follow the notion of ‘if it ain’t broke, don’t fix it’.

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. 

Perhaps the best selling point for the new Forester is that it hasn’t changed a whole lot inside. It’s spacious for its class and has physical buttons for a lot of things, while making sure the key controls like climate are always accessible on the touchscreen without needing to navigate through menus.

The steering wheel and gearshift look familiar and the general layout of the Forester seems to follow the brand’s established pattern of convenience over anything that could be annoying or complicated.

The software on the big screen is the same as any recent Subaru SUV with big buttons and a simple menu structure that means you rarely get lost. It’s not cutting-edge, but it works, much like a lot of the elements of this car.

The seats are comfortable and the seating position and steering wheel adjustment work well regardless of grade.

One element of the interior that works particularly well is visibility. Subaru made the headrest a little narrower to assist with shoulder checks and make looking over to the back seat easier. The result is a clear view, not only of the interior but also through those annoying side angles your wing mirrors might miss.

The back seat is also plenty spacious, with ample knee, foot and hip room in the second row’s outboard seats. Head and shoulder space is also fab. There’s little risk of feeling cramped in the back, even for a proper adult, especially if there’s a sunroof for that extra light.

Behind the second row, there’s 496 litres of boot space in non-hybrids, and 484L in hybrid variants, plus a switch in the boot to drop the second row from the tailgate.

That allows for 1174L and 1162L in petrol and hybrid models, respectively, though a big downside for the hybrid models is the lack of spare wheel, just a repair kit.

No spare tyre in a car you expect to be able to take off-road isn’t good enough, and it’s the key reason the Forester doesn’t score a full 10 for interior practicality. A shame, because the rest of the cabin is built for ease.

Pricing for the petrol-only Subaru Forester kicks off from $43,490, before on-road costs, putting it north of entry-level variants from rivals like the Mazda CX-5 and Toyota RAV4. It's even a little more expensive than its rivals' cheapest all-wheel drive variants.

The most affordable Nissan X-Trail AWD is $41,065 and the Mitsubishi Outlander AWD is $42,490. Even the cheapest Mazda CX-5, which isn’t an entry trim level, is $42,960.

But what the new Subie has going for it is that even from the base variant it's well-equipped. New 18-inch wheels, auto LED headlights with self-leveling, cornering lamps, roof rails and a front windscreen de-icer make the Forester AWD (its entry variant’s name) ready for a bit of adventuring.

Inside there are cloth seats and it’s got fairly standard trim, but things like dual-zone climate control, heated front seats and electric folding rear seats are all great for comfort and convenience. And a wireless phone charger and big 11.6-inch multimedia touchscreen (with wireless Android Auto and Apple CarPlay) make for an up-to-date list of features for a car in 2025.

There’s also plenty of tech in terms of running gear and safety, which I’ll get to later in the review.

The Forester AWD Hybrid has pretty much the same features, as well as paddles behind the steering wheel to adjust regenerative braking and costs $46,490.

Stepping up a grade, the $46,490 Forester AWD Premium (this grade isn’t available as a hybrid) adds auto-dipping and folding door mirrors and auto door-mirror adjustment to the driver monitoring system, plus there’s a sensor for a hands-free tailgate as well as electrically-adjustable front seats and sat-nav.

The Forester AWD Sport comes in at $48,490, or in AWD Hybrid Sport guise for $54,990, and adds a sunroof, water-repellent seat trim, a digital driver display, green stitching for the steering wheel and a dark metallic set of 18-inch wheels.

Finally, the top-spec AWD Touring costs $50,990 in petrol and $55,990 as a hybrid, with low-profile roof rails, leather-accented seats, a leather gearshifter, ventilated front seats and a 10-speaker Harman Kardon sound system with subwoofer and amplifier.

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.

Both Forester drivetrains use the brand’s existing all-wheel drive tech and a continuously-variable transmission, but the hybrid does something Subaru is keen to point out its rivals’ don’t.

The petrol version is powered by a (136kW/247Nm) 2.5-litre naturally aspirated flat-four ‘boxer’ engine that's largely unchanged.

The hybrid consists of the same type of engine with different valve controls and lower outputs of 121kW/212Nm. 

The key part is it’s assisted by a 90kW electric motor that, rather than being mounted to the rear axle and engaging when traction is needed, is placed before the transmission and sends electric power to all four wheels. Total outputs for the Hybrid variants are 145kW and 276Nm.

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. 

Subaru claims the Forester drinks 7.9L of petrol (minimum 91 RON) per 100km or 6.2L/100km in hybrid guise.

The latter's a bit of a let-down given Toyota’s RAV4 hybrid in AWD guise comes with a 4.8L/100km claim and that system's been around for ages.

Both Foresters have a 63-litre fuel tank, so could theoretically travel a maximum 797km (petrol) or 1016km (hybrid). 

Don’t expect to manage that in real-world driving, though. The trip computer reading for the last car I drove on test (a hybrid) was 7.8L/100km after a mix of highway and off-road running.

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.

On paper, the new Forester hasn’t changed to a great degree. With that engine and the late-ish introduction of a proper hybrid system, you might expect the Forester to be undercooked. 

Sure, Subaru is playing catch-up and it would be a fair to say adding a hybrid grade to its mid-size SUV in 2025 puts it behind the curve, but Subaru is leaning into its niche.

Subaru’s very happy about being able to claim the Forester is the only hybrid mid-size SUV on sale where the one hybrid motor drives all four wheels mechanically thanks to its 'symmetrical' all-wheel drive system. Then there’s the "class-leading" 220mm of ground clearance.

But as well as being capable off the road, the Forester needs to be a decent day-to-day companion. Fortunately, it’s both.

The new Forester’s road manners are a surprising step-up over the previous generation’s, which felt soft and agricultural at times.

Subaru touted the new car's incremental improvements, but behind the wheel it feels like they add up to a far superior experience. The Forester is still a little noisy - mainly wind and road noise - but many of the elements that were once a let-down are much more refined.

The CVT doesn't complain so much when called upon to pick up the pace, and the steering feels much sharper. The former could be down to a huge increase in sound-shielding, the latter likely due to Subaru’s use of the dual-pinion steering system borrowed from the WRX.

Subaru says it “reduces mechanical resistance and eliminates unwanted feedback from the motor”. It seems to have done exactly that.

Perhaps most noticeable is the suspension, which feels more tied-down and stable than before, without sharpening up too much and becoming uncomfortable. Subaru says revised spring rates, better under-body aero and a more rigid chassis all contribute.

The hybrid and petrol have different suspension set-ups, the latter feeling softer in terms of damper response but still far more confidence-inspiring than the previous-gen Forester.

It all comes together to create a driving experience that’s easy and comfortable at traffic speeds and fun and engaging at high speeds on, for example, the smooth winding back-roads of New Zealand’s South Island.

The problem for Subaru is that despite having introduced a new hybrid system, the petrol-only Forester is just as good from behind the wheel. The advantages the hybrid brings in terms of efficiency will be a draw for some, but in terms of driving dynamics the extra power and torque on offer is probably not worth the extra outlay.

Then there’s the lack of a spare wheel… which should be a requirement when you’re off sealed roads. The gravel and mud of the Canterbury region didn’t faze the Forester, though, and we put the mid-size SUV through its paces harder than most owners realistically would.

Deep mud ruts, creek crossings and jagged rocky trails were all traversed easily and comfortably, especially considering the standard road tyres fitted. 

None of the test cars were stuck due to either negligent road testers or lack of mechanical ability on the Subaru’s part, though two cars on test did succumb to an excess of water in the engine bay and went into a safety shut-down mode once we arrived back at the end of the off-road trail.

We asked Subaru for an explanation and we were told it’s a feature that saves components like the cooling fan from water damage.

“Two vehicles experienced this due to the nose being submerged from entering the water crossing at the incorrect speed and/or entry line… if water enters the engine bay at a sufficient level, a protective fuse is designed to engage to safeguard the radiator fan motor.

“This system functioned exactly as designed. Despite this, the vehicle continued to perform as intended, enabling the driver to complete the off-road course and return safely to the Homestead. 

“After cycling the ignition, a warning light alerted the driver, and the engine shut down automatically to prevent any potential damage. This sequence is outlined in the Owner’s Manual. This is a built-in protection protocol and not a fault.”

A replacement fuse meant one of the vehicles “resumed full operation,” a Subaru spokesperson added.

A maximum five-star ANCAP rating and nine airbags (dual front, dual front side, dual curtain, driver’s knee, far side and front passenger seat cushion) should all mean peace-of mind in case of the worst, but Subaru also has a long list of safety features to avoid that being necessary.

The brand’s 'EyeSight' safety suite features adaptive cruise, emergency lane-keep and centering with departure warnings, pre-collision braking and auto emergency steering, brake light recognition as well as speed and sign recognition, plus there’s a driver monitoring system and a series of radar and cameras that allow for a surround-view of the car.

The Forester also has a feature Subaru is very proud of, which detects a lack of response from the driver via inputs, and gradually tries to wake or alert the driver through sounds and gentle jolts via braking before eventually coming to a safe stop and unlocking the doors to allow assistance.

To Subaru’s credit, this all features on every variant.

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.

Subaru‘s five-year, unlimited kilometre warranty is behind the curve for mainstream brands with many offering between seven and 10 years, but its eight-year/160,000 kilometre hybrid high-voltage battery warranty is par for the course.

Servicing intervals are every 15,000km or 12 months, with servicing pricing locked in for the first 75,000km or 60 months of ownership. Total cost over this time is $2299 for either drivetrain, with the cheapest service being $347.95 and the most expensive $679.30 (at 60,000km or 48 months).

Subaru also offers 12-months complimentary roadside assistance.
