MG Im5 vs Toyota Prius C

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.

It's as if the the future is firmly rooted in the past at Toyota. The Prius is still undoubtedly clever, frugal and easy to drive, but it is feeling so old in places that the bad had begun to weigh on the good. If you're a tech-head or have a right foot crafted from lead, then there's nothing to see here. But if the thought of saving money at the bowser sets your heart aflutter, then step right this way.

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 good news is that it doesn't look quite so quirky as the full-size Prius. The not-as-good news is that it's still no beauty-contest winner. Not helping matters was the fact our test vehicle was painted in a retina-burning yellow (they call it Hornet Yellow, and it's new for 2018) that looked almost nuclear.

Viewed front on, the blacked-out section of grille and bumper gives the littlest Prius a vaguely manta ray-shaped front-end, while the headlights climb both upwards and back into the body, lending a sense of sportiness to this very unsporty hybrid. From the back, the chunky bumper, vertical taillights and rear windscreen spoiler all add a little attitude to the design.

Inside, you'll find a small but premium-in-places space, with a gloss-black stereo surround that angles the main controls toward the driver, while the digital driver's binnacle is pushed toward the centre of the car, displaying speed, fuel and other key info above the stereo, rather than in front of the steering wheel.

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. 

Not very. This is a Yaris-based city car, let's not forget.

That said, it never feels cramped up front, with enough shoulder and headroom to ensure you feel separated from your fellow passengers, where you'll also find two cupholders, and an infuriating USB connection housed in the touchscreen - so your cord dangles from the dash when connected.

Climb into the back, and you'll find yourself in a pretty snug space. Sitting behind my own (5ft-8inch) driving position, it's only the scalloped back of the driver's seat that affords me any clear air between my knees and the seat in front, and the space behind my head and the roof lining is minuscule, too. But again, we're talking city car space here, so you can't expect to lounge about back there.

The ambience in the backseat leaves a little to be desired, though. The door trim pushes into the passenger space, and the plastics used in the rear are rock hard. There's a single cupholder to share, and a seat-back pocket on the rear of the passenger seat, but that's it; there's no vents, USB or power sources. There's no bottle-room in the rear doors, either.

An easy-access boot space will swallow 260 litres with the 60:40 rear seats in place. And there are two ISOFIX attachment points, one in each window seat in the back.

We've just spent a week behind the wheel of the Prius c i-Tech; the top model in the two-variant range, sitting above a cheaper model known simply as the Prius c.

At $26,540, it ain't cheap for a city car (and it's $4k more than the most-expensive Yaris on which it is based; more worryingly, it's only $1500 cheaper than an Audi A1), and the standard features list is more a novella than War and Peace.

Outside, you'll find 15-inch alloy wheels, remote unlocking, LED headlights and front fog lamps, while inside you'll leather-look seats (they're actually vinyl), sat-nav and climate-control.

Tech is covered by an  (old-school feeling) 6.1-inch touchscreen that pairs with a six-speaker stereo, but there's no Apple CarPlay or Android Auto.

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.

Under that little hood lives a 1.5-litre, four-cylinder petrol engine good for 54kW, which pairs with a 45kW electric motor. Toyota lists combined outputs at 74kW at 4800rpm and 111Nm at 4000rpm.

That hybrid setup partners with a CVT automatic, pumping power to the front wheels.

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. 

If that last section didn't impress, this one surely will. The little Prius c will sip a claimed 3.9L/100km on the combined cycle.

That's very low, and the fact it accepts cheaper 91RON fuel makes it a very affordable car to run. Except... the onboard computers revealed a slightly less-impressive 5.1L/100km after my time with the car.

Emissions are a claimed 90g/km of CO2, which is very good.

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.

In much the same way that you don't buy an exotic performance car for its ability to run to the shops, you're unlikely to be buying the Prius for its ability to set your pulse racing.

But happily, it doesn't feel wobbly or disconnected, either. It's aided by being such a small package, and when you're not wafting silently about in electric mode, and you've coaxed that little petrol engine into life, it serves up more than enough poke to navigate the city, and even to leave the slow-reactors in your rear-view mirror at traffic lights.

The ride is good, too, feeling connected to the road below without feeling uncomfortable, although the little Prius does tend to track with the corrugations in the road, leaving you to wrestle it back into line. That's a job made easier by light and surprisingly direct steering, which feels tailor-made for the city.

Finally, the leather-look seats are comfortable, even over long distances, the razor-thin A-pillars make forward vision easy and it's a very simple thing to drive and manoeuvre  into parking spaces. And all of those are good things.

Not so good? Well, the entire drive experiences feels a little beige and emotionless, it can get noisy and there are parts of the cabin that feel downright cheap. Worst of all, though, is that for a car that once heralded the future, it's feeling very, very dated.

But there are some amazing quirks attached to driving an (almost) electric car, including the delivery of eco awards for using the least amount of fuel (they were awarded for 2.6, 3.2 and 3.6L/100km over as much as 25km - none of which occurred during my tenure). The hardest thing to get used to was the absolute silence served up in electric mode. I counted four seperate occasions when I walked away from the car with it still turned on.

Every Prius c arrives with seven airbags, along with a reversing camera and... wait, that can't be it, can it? Oh... Forget AEB, lane-departure warning and the like, this future-focused Prius has a safety package firmly rooted in the past.

It was awarded the maximum five-star ANCAP safety rating, but was tested back in 2014.

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.

Toyota offers a three-year/100,000km warranty, while the batteries are covered for eight years or 160,000km. The car's six-month service intervals might sting a little, though, but with each service capped at $140 for the first three years, even taking two trips to the dealership a year isn't too expensive. Just annoying.
