Toyota GR Yaris vs MG Im5

What's the difference?

The GR Yaris GTS with the Aero Performance Package is a so wonderfully special with its brilliant engineering, mind-blowing dynamics and fun-to-drive nature. The new aero package makes an already angry beastie look furious, making it the perfect enhancement that's also functional.

The only lower marks here are for warranty, fuel use and practicality. But if there was a score for fun it'd be a 10/10.

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 GR Yaris exists so that Toyota could go racing in the World Rally Championship. As with many racing series it required Toyota to build a road-going version of their Yaris race car, also known as a homologation vehicle. It’s a good deal, they get to race, you get a race car for the road. And so the GR Yaris was born. 

Wildly different from a regular five-door garden variety Yaris, the GR Yaris is a hand-built three-door hatch with a wider track, wider and lower body and the use of forged carbon and aluminium for lightweight construction.   

The GR Yaris already looks very angry, but the GTS Aero Performance Pack makes it look furious. It adds a huge adjustable rear wing, fender ducts that channel air, a front spoiler lip that aids stability, a giant bonnet scoop to help release air, and rear bumper ducts to reduce drag. 

The GR Yaris’s cabin was redesigned for the 2025 update and that saw the dashboard angled more to the driver much like in a race car, but it's more functional than fancy and it’s all very plain.

Still, we’re not complaining. The seats are lovely and the red stitching is a nice touch but this isn’t a Lexus. It’s supposed to favour function over form and so the design is absolutely fitting. And by function I mean dynamics and not 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.

The regular Yaris is small, the GR Yaris is smaller at 3995mm end-to-end and with two fewer doors. As a tall person (I’m 1890mm end-to-end) the space on board is adequate up front with just enough knee, head and elbow room.

The GR Yaris is a four seater with the two rear seats accessed through the front doors. There’s not much room in there for adults and not even my lanky 11-year old would be happy in there. Still if you need to carry three other people, technically you can.

Cabin storage is limited to fairly large door pockets and two cupholders between the front seats. There is a little shelf carved into the dashboard which is great and a small glovebox below it.

Boot space is tiny at 174 litres but again this is a small car with other priorities. 

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.

It still boggles my mind how 221kW and 400Nm is extracted from a 1.6-litre three-cylinder petrol engine but here we are. The GR Yaris has this set up with this output, along with all-wheel drive. 

Thanks to lightweight materials such as forged carbon and aluminium the GR Yaris weighs nothing in car terms - just 1300kg - so acceleration from 0-100km/h is a rapid 5.1 seconds.

I’ve already detailed the juicy engineering bits the GTS Aero Package is fitted with, from the limited slip diff to the adjustable rear wing, and it’s not an exaggeration to say that not many small hatches are this gifted with this kind of genius.

Our test car has an eight-speed automatic, which is easy to drive in city traffic. However, I'd opt for the six-speed manual because if you've come this far you may as well go the whole way.

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 GR Yaris is a hungry beastie that eats through its 50L petrol tank fairly quickly and then wants more. Toyota says you should see 9.1L/100km of 98 RON used in the automatic and 8.2L/100km with the manual over a combination of driving conditions. 

Stop-start city driving in traffic saw fuel use increase dramatically to 13.0L/100km in the auto. According to our car's trip computer, my own testing used an average of 14.5L/100km after mainly suburban driving.  

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. 

There’s been a multitude of electric cars through the test garage over the past six months and the GR Yaris is like a diamond found in a tub of Lego when it comes to driving.

So much sound. The three cylinder snarls on start up sending vibrations into the cockpit and up through the steering wheel, the transmission can be heard engaging gears, the big brakes creak as they’re released. And we’re hardly even moving yet. There’s so much theatre. It’s all real and I love it!

I even love that in the first 10 minutes of driving, a message appears on the instrument cluster asking that excessive acceleration be avoided while the engine is cool. You don’t get that beautiful inconvenience in an electric car.

But when you can excessively accelerate (on a race track of course, right?) it's wonderful and it's loud. Lift off, and the wastegate lets out a little "weeee!" in excitement.

I don't need to tell you that the GR Yaris handles better than just about anything in this price range and while the ride is firm and speed bumps feel like you’ve hit a gutter I still drove the GR Yaris every day, even to do the school run, because it is so much fun. Meanwhile my hybrid long0term test car looked lonely in the driveaway all week...

Being an automatic makes it easy to drive in traffic and the small size makes finding parking spots quick and simple.

Visibility is good, steering is excellent, the seats are big enough to accommodate me but snug enough to offer good lateral support, too.   

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.

The GR Yaris is covered by Toyota's five-year/unlimited-kilometre warranty which is lacking compared to many other mainstream manufacturers’ seven-year-plus warranties. The good news is that the engine and driveline is covered by an extra two-year warranty.

Servicing is capped at about $300 for the first six visits, although services are six months apart which means that after three years you’ll run out of capped-price servicing.

Still, Toyota’s reputation for reliability does provide some peace of mind. 

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.
