Lexus LBX vs MG Im5

What's the difference?

Lexus has managed to combine two cars in one. A fast, impossibly fun back-road blaster perfect for weekends on your favourite winding roads, and a competent, compact city SUV that will easily handle urban runabout duties every day of the week.

It’s this duality that struck me the most. I would happily live with the Lexus LBX Morizo RR. 

If you need a bit of space, maybe look elsewhere. But if you’re passionate about dynamic driving, and value comfort and a premium experience, this little rocket is hard to beat.

Note: CarsGuide attended this event as a guest of the manufacturer, with accommodation and meals provided.

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 regular LBX is a spunky little car with a lot of road presence. I’ve been a fan of the exterior design since first seeing one in the metal. Short overhangs, nuggety proportions, well designed tail-lights and a pert rear end - it all works for me.

For the Morizo RR, Lexus has wisely exercised some restraint when it comes to exterior flourishes. It is nowhere near as wildly styled as the Yaris GR, for example. And that makes sense. This is, after all, a Lexus. 

It’s a smart move, too. It’s subtle but still has intent. 

The Morizo RR gains styling tweaks unique to the grade including 19-inch forged aluminium wheels, red brake calipers, a different front and rear bumper design, a rear spoiler, air intakes front and rear and a dual exhaust.

Inside, the main differences are the inclusion of red stitching, sports seats, some unique inserts, and the use of synthetic suede on the centre console, dash and doors.

The LBX interior design is functional and premium with nice materials throughout. 

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 LBX is a compact little SUV so if you’re after something to fit a family of four, look elsewhere. But if you don’t need the space, it’s a great city car.

Up front it’s easy to find the right driving position thanks to all of the adjustability of the seat and steering wheel.

Those sports seats are supportive and hug the body, but not too much as some of Lexus’ European rivals do. They’re also very comfortable - almost edging firm but never uncomfortable.

The Lexus multimedia system is functional and has an easy-to-navigate menu set-up, but lacks any pizzazz. Better graphics would help with engagement.

Storage wise, there’s a wireless charger slot at the bottom of the centre stack, a cupholder with a narrow slot for another device next to it, and a deep but narrow secure central storage bin with another cupholder.

You might not fit big bottles into the door bins as it’s pretty tight.

I wasn’t sure about Lexus’ one-touch interior and exterior door handles when they first rolled them out, but I now think it adds a classy point of difference to its rivals.

That second seating row is tight, especially for taller folk. I had just enough legroom (but plenty of toe room) sitting behind my 183cm (6'0") driving position, but I wouldn’t want to sit back there for a long road trip. Headroom, however, is ample. My noggin didn’t even scrape the headliner. You’d struggle to fit three adults back there but a couple of kids should be fine.

Amenities include a pair of USB-C ports and two map pockets, but the rear row lacks any adjustable air vents or a fold-down centre arm rest. And the bottle holders in the rear doors won’t fit much at all. 

The rear row folds 60/40 and if you need to haul lots of luggage or shopping, you’ll definitely need to lower that rear row because the boot is small.

Lexus says it can swallow 266 litres, which is tight. There’s no spare wheel of any kind, just a tyre repair kit.

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.

Powering the LBX Morizo RR is an excellent 1.6-litre turbocharged three-cylinder petrol engine, which is the same unit found in the Toyota GR Corolla and Yaris hot hatches.

The Lexus loses some power and torque compared with those models so the outputs are 206kW and 390Nm. The Toyota cousins offer 221kW/400Nm each.

This engine is paired with an eight-speed torque converter automatic transmission and it has electrically controlled all-wheel drive with a Torsen limited-slip differential.

You can race from zero to 100km/h in just 5.2 seconds.

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.

While the hybrid versions of the LBX are known for their fuel efficiency, it’s less of a focus for the Morizo RR performance model.

It has an official combined (urban/extra-urban cycle) fuel figure of 9.2 litres per 100 kilometres, which is more than twice the figure of the hybrid.

CO2 emissions sit at 209g/km and the LBX has a 50-litre fuel tank. You will need to fill up on the expensive stuff though as the Morizo RR requires 98 RON fuel. Theoretical range between fills is around 540km.

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. 

I had high expectations for the LBX Morizo RR and I’m pleased to say they were met.

What a phenomenally capable little car.

Lexus is at pains to point out that its mechanical cousins - the Toyota GR Corolla and Yaris - are motorsport bred and therefore more raw and hardcore.

The premium brand knows it needs to be able to attract new buyers with a car like this, while also satisfying its loyal base.

Lexus did this by building a hot hatch (okay, it’s an SUV) that you can easily live with day to day.

I spent an enjoyable few hours behind the wheel of the Morizo RR on a stunning Autumn day in Victoria’s Yarra Ranges driving on some incredible roads. The twists, bends, undulations and more showcased how tight this car is.

First up that engine is an absolute gem, and I don’t miss the extra kilowatts found in the Toyota models. There’s very little turbo lag and the LBX picks up pace quickly but in a focused, fun manner.

The engine note is also a delight to behold, especially when you push it hard. Although on coarse chip roads a fair bit of road noise creeps in, to the point that it's boomy.

The transmission is a perfect pairing for the engine, too, offering slick shifts without holding gears unnecessarily. I didn’t miss the manual box found in the Toyotas, either. But the paddle shifters and a true manual mode (it won’t shift unless you flick the paddle) adds to the experience.

The brakes are strong but not too pinchy and the steering is as sharp as you’d hope, while offering just enough weight. 

Then there’s the grip. The all-wheel drive system “automatically distributes the front-rear torque according to road conditions and grip”, according to Toyota.

That AWD grip always inspires confidence during dynamic driving in a car like this and the LBX sticks to the tarmac like nobody's business. Despite some damp sections of road higher up the ranges, no slip was detected. It feels glued to the road.

If that’s not enough, the Lexus surprises with its compliant and even comfortable ride quality. Many hot hatches (or hot SUVs) have a firm ride due to a chassis set-up geared to performance driving. 

Somehow Lexus has ensured the damping settings shield the occupants from the worst bumps. Only deep potholes make their presence felt.

And that’s the beauty of this car. It feels so beautifully engineered, with a clear focus on performance, but it’s not a brutal experience. You never feel like you could easily lose control in this thing. You can punt it into a tight bend and feel confident it will stay the course.

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.

Lexus covers the LBX Morizo RR with its five-year, unlimited kilometre warranty and capped-price servicing for five years at a cost of $695 a service.

The schedule for servicing is tight at every six months or 10,000km, whichever occurs first, so you’ll be at the dealership a bit with this one. These are the same servicing terms as the GR Corolla and Yaris.

Lexus’s 'Encore' owner benefits program includes some cool stuff, too, like a valet parking service at certain venues, and you can even swap your Lexus for a different model for a set amount of time with the On Demand service.

Lexus Encore also offers exclusive access to events and venues, as well as special offers at hotels and restaurants.

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.
