MG Im5 vs Lexus CT200h

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 cheapest Lexus of them all isn’t chasing badge snobs with the CT200h as blatantly as Mercedes-Benz, BMW and Audi do with their entry level cars… but it’s perhaps not quite the Lexus you’d expect it to be.

It has a lovely front-of-cabin, for example, but there’s a lot of last-gen Prius in plain sight in the rear of the cabin.

The hybrid powertrain, too, is noble in concept, but the day-to-day reality is that it’s not as nice to drive, especially town to town, as a regular petrol-powered car of similar size.

The foot brake, silly multimedia joystick and odd gearshifter also spoilt the party a bit.

Empty nesters who are looking for a nice city runaround with a tinge of greenwash about it will love it… and if the current Prius is anything to go by, the next CT will be a very good thing indeed.

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.

There are some light external revisions for the latest update of the compact Lexus CT200h. New grey 17-inch alloys are unique to the Sport Luxury, along with a black roof treatment, new L-shaped LED driving lamps that match new-design LED tail-lamps, while Lexus designers have also added its new spindle grille to the brand’s smallest model.

It manages to be inoffensive, but it doesn't really reflect the brand's latest design language of 'real world concept cars' like the NX and the LC ranges.

Inside, a couple of new leather colour options are available for the CT200h, while the addition of the wide-format 10.3-inch screen to the top of the centre console is the single largest change. Interestingly, the steering wheel controls appear to have regressed a little from the previous model, no doubt brought about by the addition of the new driver aids.

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. 

The CT200h basically replicates a small hatchback in terms of interior size. It'll seat five, but if you try to put three adults across the back, they won't be particularly happy about it. 

The roofline is quite low and the car’s waistline is high, which makes the glasshouse feel small. Room in the front is adequate, but only just for taller drivers; the sunroof, as fitted to our test example, takes away a good chunk of headroom, despite the CT200h standing just 5mm lower than a Corolla overall. 

The seats themselves, too, are mounted just a touch high to be comfortable for taller drivers, while rear seaters will complain bitterly about being stuck behind my (184cm) driving position. However, my more diminutive wife pronounced herself very comfortable behind the wheel and in the passenger seat.

A nice, small steering wheel sits in front of a single-dial dash that sports two digital screens either side. The left-hand screen changes when you change the drive mode dial between Eco, Normal, and Sport. And there's also a full EV mode button in handy reach. 

Two cupholders are line astern between driver and passenger, although storage is at a premium thanks to the size of the car. Climate and multimedia controls - and even an old-school CD player – flow right through underneath the centre console, which steals away valuable space. There are no extras like wireless charging bays, nor is there Apple CarPlay or Android Auto.

There are bottle holders in the door, but don't try and stash anything that's over one litre in size because it just won't fit.

It's quite an austere proposition for rear-seat passengers, with no bottle holders in the doors, no cup-holders and no charging points. There are fixed vents under the front seats and on the right side of the rear area, so it's not a complete desert, and there are ISOFIX mounts for two child seats in the rear.

Another practicality issue that's unique to the CT200h is the gear shifter. It operates as a spring-loaded joystick, and unless you're watching the dash indicator, it can be tricky to know which gear you're in. Other car makers have actually recalled cars with this style of transmission stick, and it's certainly something that you have to get used to. 

Likewise, the old-school foot brake is certainly an anachronism in something like a Lexus.

Based on the previous generation Prius, the nickel-metal hydride battery for the CT is hidden underneath the rear seat, so it doesn't steal away too much boot room. However, the boot floor is still quite high, and the area is rather small at 375 litres with the seats up. There is 985 litres available when you drop the seats, but the aperture is short and narrow, so larger items will be a squeeze. There is a space-saver spare nestled away underneath the boot floor, too.

Another practicality note in the negative column is Lexus's insistence on the odd joystick control for its multimedia system. It's simply not very good. It’s imprecise when compared to a touchscreen, the action and feel of our test unit was very much less than premium, and it’s just awkward and clumsy to use. The CT is not the only Lexus to use it, but we wish the company would just see the light and ditch it all together.

The 1.8-litre petrol-electric CT200h comes in three different flavours – the Luxury, the F-Sport as tested here, and the Sport Luxury. The range now kicks off at $40,900 (up $2150) and peaks at $56,900 with the Sport Luxury (up $810).

The F-Sport may be a little lacking in the actual ‘sport’ department, but it’s is pretty flush with flash kit, including not one but three motors (one petrol and two electric), auto lights and wipers, a wide 10.3-inch multimedia system, leather seats, dual-zone climate control and new 17-inch alloys.

At $50,400 plus on-roads, the F-Sport has jumped in price by $1960, but it’s gained a host of new gear, including a new driver aid system that adds auto emergency braking (AEB), pedestrian-detecting pre-collision warning system, lane departure warning with steering assistance and adaptive cruise control.

There are also LED headlights and taillights, as well as revised styling for the front and rear bumpers.

The CT will be cross-shopped against other premium tiddlers like the Mercedes-Benz A-Class, Audi’s A3 and the BMW 1 series. Comparing it like-for-like in the hybrid category, there’s the top spec Toyota Prius i-Tech, while Nissan’s Leaf could theoretically be lumped in both on price and on environmental grounds.

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 1.8-litre twin-cam petrol engine makes a relatively low 73kW and 142Nm, while a 60kW, 207Nm electric motor that’s also connected to the front wheels chips in its share.

Combined, the system produces 100kW, while the torque figure translates to around the 150Nm mark. That juicy 207Nm doesn’t come into play, sadly, given that the petrol engine – which is built to run cooler than a traditional Otto cycle engine, and therefore more efficiently – does most of the work.

Throw in a transaxle for the electric motor and a power inverter, and things are getting complex. However, if the Prius is any indication, the CT200h’s drivetrain is durable and relatively serviceable, with batteries estimated to last ten years or longer.

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. 

Here’s the odd thing – over 220km of largely highway driving, I couldn’t get the CT200h under a dash-indicated 10.4 litres/100km, against a claimed combined fuel economy figure of 4.4L/100km. 

I topped the tank off with 18 litres of fuel, which works out at a closer 8.8L/100km… but it still ain’t anything like 4.4. 

Another owner I spoke to, though, said he regularly records high fives with his CT200h in mixed conditions.

It runs a 45-litre tank that’ll happily take 95 RON fuel.

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.

If you've ever driven a Prius, then you'll be very familiar with the way that the CT drives. Based around a 73kW Atkinson cycle petrol engine which focuses on fuel efficiency rather than outright power, a 60kW electric motor (the pair combine to produce 100kW in total), a nickel-metal hydride battery array and a CVT gearbox, the CT200h – like the Prius – is a bit different to a regular hatch.

Under light throttle, the CT is quiet and moves along quite well, and you can even use full Electric Vehicle mode at speeds under 45km/h for a brief amount of time, (slightly less than two kilometres), and with a very gentle right foot.

The battery array is recharged via the petrol motor as well as regenerative braking (where heat energy is captured and directed back to the electric system) – but unlike a petrol-electric plug-in hybrid, there’s no way to stick a 240v cable into the CT to top up the battery. 

It has the unusual whines and odd noises that you would associate with a partly electric car, but the petrol motor sounds just like a regular old four-pot petrol unit, and it’s running most of the time.

One issue with the drive of a hybrid is its ability, or the lack thereof, to get off the line in any sort of hurry. You really have to mash the throttle to get going, which takes some getting used to. There’s also some hesitation and un-Lexus like thumps from the drivetrain if you confuse it by almost stopping then taking off again.

The CT200h’s biggest bugbear is that the fourth generation Prius exists. Built on a more sophisticated newer-generation platform and with a more refined drivetrain, the new Prius is a great insight into how good the next CT will be – and what the shortcomings of the current one currently are.  

The CT works well in high-traffic city environs, where a light throttle foot helps get the best out of the unusual drivetrain. Lots of lag from rest is an annoyance, as is an excess of CVT whine under hard efforts, but the CT200h pootles around town very well.  

Its small size does play against it when it comes to keeping out road noise at freeway speeds, though the CT is superior to most other similarly sized cars in this regard. As an aside, its build quality is nothing short of amazing, with minimalist panel gaps, a tight interior and lashings of paint on every surface.

Part of the update for 2018 is the addition of several driver aid systems, including AEB across the range, lane departure control with steering and adaptive cruise control. 

The F-Sport also has reversing camera and eight airbags as standard, ensuring the maximum five-star ANCAP safety score it managed in 2017.

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.

Lexus sells the CT with an unusual four-year/100,000km warranty, which includes roadside service coverage. The battery pack has an eight-year/160,000km warranty, while Lexus would like to see you back for a service every 12,500km or 12 months.
 
It’s not just about a warranty or a service interval with Lexus, though. For decades now, its customer service record has topped all industry measures, and everyone we know who has bought a Lexus with their own money has raved about the quality of the service received. 

As well, it’s a level of service that’s provided across the range. It’s a tangible benefit of buying a CT200h.
