GWM Cannon Alpha vs MG Im5

What's the difference?

The Cannon Alpha Ultra PHEV combines five-star safety, a confident warranty, lavish luxury and short-haul electric driving for a competitive price. However, from a pure workhorse perspective, its class-benchmark 3500kg tow rating is offset by a modest payload limit, plus an awkward spare tyre location which could be a deal-breaker for some tradies as it compromises working floor space and the securing of loads.

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.

Our test vehicle shares the same body-on-frame chassis design, twin A-arm/coil-spring front suspension, four-wheel disc brakes and electric power-assisted steering as the model it replaces, but the previous leaf-spring live rear axle has been replaced by a multi-link coil-spring arrangement. External chrome has also been greatly reduced.

Its luxurious leather-accented interior has a spacious and classy feel with a panoramic sunroof and opulent mix of surface finishes, but some tradies might consider such indulgences too fancy for carting muddy-booted crews.

The PHEV’s larger rechargeable battery pack uses up all the underfloor space behind the rear axle usually occupied by a full-size spare tyre. As a result, the steel-rimmed spare has been moved to a conspicuous location in the load tub, which not only looks like an afterthought but is far from ideal for workhorse duties (see Practicality).

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.

Our test vehicle’s substantial 2810kg kerb weight is 235kg heavier than its hefty Alpha Hybrid predecessor, due largely to the bigger battery and electric motor. That makes it about half a tonne heavier than numerous conventional turbo-diesel 4x4 dual cab utes.

This substantial kerb weight contributes to a sizeable 3495kg GVM, yet results in a 685kg payload rating which is modest compared to some turbo-diesel rivals with genuine one-tonne capabilities.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer, but with its 6745kg GCM (or how much it can legally carry and tow at the same time) that would require a 250kg reduction in payload (from 685kg to 435kg) to avoid exceeding the GCM.

While it’s unlikely owners would need to tow at the 3500kg maximum, it’s important to be aware of these numbers if the need arises, as that 435kg of payload could easily be used up by a crew of tradies before you could load any of their tools.

The vertical mounting of the spare wheel in the load tub not only reduces floor space and load volume but also restricts the securing of loads, given there’s no anchorage point accessible in the right rear corner of the tub.

So, all load straps extending rearwards must share the same left-side anchorage point, which is far from the ideal even spread provided by four-corner load restraint. This spare wheel location needs a rethink (perhaps a swing-away carrier favoured by 4x4 wagon owners would be better).

We also noted the big button on the two-way tailgate, which enables it to split into a pair of hinged doors, stopped working during our test. Fortunately, it could still open the tailgate as a conventional single unit.

There’s ample interior space, not only for front seat occupants but also those in the back. That includes tall people, given I’m 186cm and have at least 40mm of knee room when sitting behind the driver’s seat when set in my position.

There’s also about 80mm of rear headroom, despite the presence of a full-length sunroof which can often compromise this dimension. However, shoulder-room is tight for three adults, so two would be preferable for long trips.

Front-of-cabin storage includes a large-bottle holder and bin in each front door, plus a large glove box, overhead glasses holder and a pull-out compartment for the driver in the lower dash.

The centre console offers wireless phone-charging and a lidded box (with internal air-con flow available) and two small-bottle/cupholders. Another storage nook in the lower right-side of the console offers two USB ports, a 12-volt socket and enough space for a phone.

Rear passengers get a large-bottle holder and bin in each door, pockets on the rear of both front seat backrests and small pull-out drawers under each outer seat. The rear of the centre console also offers adjustable air-vents, a pair of USB ports plus controls for seat heating/cooling and the sliding rear window.

The fold-down centre armrest offers another wireless phone-charging pad, pop-out twin cupholders and a hidden compartment for storage of phones or other slimline items.

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.

The Alpha PHEV drivetrain consists of a 2.0-litre, four-cylinder, turbo-petrol engine that produces 180kW of power and 380Nm of torque. This is paired with an electric motor that adds another 120kW/400Nm, so combined they officially produce 300kW and 750Nm.

The electric motor draws its energy from a 37.1kWh lithium-ion rechargeable battery. GWM claims it can be charged from 30 to 80 per cent in less than 30 minutes using 50kW DC charging, or around 6.5 hours using AC charging.

It also has up to 6.0kW of V2L (Vehicle to Load) functionality, using a dedicated adapter cable which plugs into the vehicle’s charging port and provides a standard three-pin AC outlet for numerous electric tools and appliances.

The nine-speed torque converter automatic, which offers sequential manual-shifting using steering wheel-mounted paddles, is paired with the familiar Borg Warner ‘Torque on Demand’ 4x4 system.

For road use, this has three selectable drive modes ('Standard'/'Sport'/'Eco') with the centre differential remaining unlocked to automatically adjust torque delivery between the front and rear wheels in response to any loss of traction.

For off-road use, selecting '4H' (4x4 High Range) or '4L' (4x4 Low Range) locks the centre differential to provide an even 50:50 torque split between the front and rear wheels. 4L traction can be optimised by engaging the front and rear diff-locks.

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.

GWM claims official combined average consumption of only 1.7L/100km when the highly-charged battery allows most driving to be done in pure electric mode. GWM also claims an official ‘low charge’ figure of 7.9L/100km, when the battery is depleted and the petrol engine is doing most of the work.

It has an NEDC electric-only driving range of up to 115km and a ‘hybrid’ driving range (petrol engine and electric motor combined) of up to 1060km. The petrol engine drinks standard 91 RON unleaded.

The dash display was showing average petrol consumption of 6.4L/100km at the completion of our 324km test, which comprised a mix of suburban, city and highway driving of which about one third was hauling a heavy payload. This was lineball with our own figure of 6.2 based on fuel bowser and tripmeter readings.

Starting with 90 per cent battery charge, we completed 72km of electric-only driving before it automatically switched to hybrid mode when the charge reached 14 per cent. The system would not allow charge to drop lower than that for the remainder of our test, which was conducted in hybrid mode.

So, based on our own test figures, GWM’s claim of more than 1000km of hybrid driving range is credible from its combined 37.1kWh battery and 75-litre fuel tank capacities.

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. 

It has good steering feel with sophisticated ride quality, the latter thanks to four-coil suspension and substantial sprung weight which helps iron out the bumps and deliver a ride that’s more SUV than ute.

Flatten the accelerator from a standing start and up to 750Nm of torque responds with impressive force, even though you can feel that every one of those Newton metres is required to overcome more than 2.8 tonnes of inertia to get this jigger moving swiftly.

Although the option of sequential manual-shifting is available using the steering wheel paddles, we spent most of the test in auto mode as it felt like it was getting the best out of this complex drivetrain.

It’s a competent highway cruiser, too, with the petrol engine requiring 2200rpm to maintain 110km/h with low noise levels.

To test its GVM rating we forklifted just over half a tonne (505kg) into the load tub, which with driver equalled a 600kg payload that was less than 90kg under its limit. The rear coil springs compressed about 50mm, but there was no evidence of bottoming-out on our test route.

Ride, handling and braking were largely unaffected, along with the drivetrain which made light work of our 13 per cent gradient, 2.0km set climb at 60km/h.

Engine-braking on the way down, in a manually-selected second gear, was equally impressive. It never exceeded the 60km/h speed limit, even though its total vehicle weight of around 3.5 tonnes was being restrained by only a 2.0-litre four and regenerative braking.

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.

Warranty cover is seven years/unlimited km with an eight years/unlimited km traction battery warranty and seven years of roadside assist.

Scheduled servicing is every 12 months/15,000km whichever occurs first. GWM offers seven years of capped-price servicing totalling $4615, or an average of $659 per service.

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.
