Lexus NX250 vs MG Im6

What's the difference?

So, is the cheapest Lexus NX the grade you’d skip? Depends on where you live and drive.

If you’re urban based and bound, save up a bit more and go the petrol-electric hybrid; otherwise, out on country roads especially, the spirited and sporty NX 250 is more than up to the task.

Either way, though, the latest NX is finally fit to fight the other premium brands’ medium SUV efforts, head on and held up high. Welcome to big mid league, Lexus.

Ignore or underestimate at your own peril, everybody else.

A super solid first outing from the IM brand. Don't let the pricing fool you, there is still bang for buck on offer in the IM6 Performance, even if it at times feels a bit too digital for my tastes.

Lexus says that nearly one million of the original-shape NX versions were produced, so there’s no way that the brand was going to mess with the styling of the latest version. Which explains why picking new from old is a serious case of trainspotting.

But that migration to the TNGA GA-K platform has brought some benefits from a design point of view. The styling now breathes more, especially when viewed rear-on, thanks to a body that’s 20mm longer and wider, as well as a handy 30mm wheelbase stretch.

Drilling into the details, the headlights have an LED ‘tick’ motif, the corporate ‘spindle’ grille isn’t as in your face and the rear gains ‘LEXUS’ lettering spelled out, probably to accentuate stance.

Crisp and elegant, the design works well. This is a handsome machine. Looks expensive too.

I feel almost mean saying this, because there will be plenty of people who like the way the IM6 looks, and I don’t want to rain on their parade. But… I’m not one of them.

It reminds me a bit of the pre-facelift Tesla Model Y, in that it’s largely feature-less and a bit blobby, and there’s not a sharp angle anywhere to be found on the thing. Premium to me means powerful and assured — picture just about any Audi — whereas I just find this a bit bland and soft.

Anyway, I do like the big alloys, the insulated glass roof and the light treatment front and rear.

And I like the cabin. The seats aren’t leather, but they’re super thick and comfortable, and there is a genuinely premium air in the cabin, helped by the acreage of screens and the quality elements, like the little door panels.

The doors unlatch electrically, matching the pop-out door handles outside, but they can be a bit fidgety. Someone from MG told me how they worked (you kind of cover the handle and let the door come to you) but I watched everyone else who tried to open them struggle. If you're at the point where you have to explain how a door handle works, you might have over-egged the pudding.

The second screen below the main one acts a bit like a mobile phone. You can alter your home screen widgets and access the main menu, even as Apple CarPlay is synched at the top. You’ll get used to it, I’m sure, but I found it to be a bit fidgety.

Actually it reminds me a little bit of the Lexus trackpad, or whatever that hateful system was called, where you controlled the main screen via a little mousepad thing, though happily it’s nowhere near as annoying as that was.

Though distinctively attractive and obviously well built, the previous NX was quite small for a medium-sized SUV inside, with tight rear legroom.

It also had a nonsense mouse-operated multimedia controller that was fiddly, annoying and counter-intuitive to use.

Thankfully, the new-from-the-ground-up design has rectified both these issues in the latest version.

Now the NX is properly medium-sized, and so easier to get in and out of, as well as palpably roomier front and rear. Employing the RAV4’s TNGA architecture results in a lower and roomier cabin, that benefits all in terms of packaging.

Being the entry-level 250, you might not expect much in terms of interior presentation or style, but Lexus Australia’s product planners have been deft in specifying this grade to make it look luxurious and on-brand.

Body-hugging bolstered perforated leather front bucket seats, in our example finished in a black/cream hue with orange stitching, belie the base-grade reality of the 250. This scheme is also found on the centre console, armrest and door cards, lifting the ambience no end. It looks, feels and smells expensive in here.

The only thing that seems to be missing is a smartphone charger. That's part of a $3K option pack that also throws in a sunroof and foot-operated actuation for the electric tailgate. Not bad.

Then there’s the driving position, with an electrically-operated reach/height adjustable steering column and a multi-configurable seat to help find the right spot. All-round vision is also better than you might expect, no doubt helped out by huge exterior mirrors and a large reversing camera screen.

Typical Lexus-style classy digital instrumentation, directly ahead, are positioned in such a way that you’re not really aware of/missing the available head-up display in higher grades. Though it takes a quick amount of familiarisation, all the info there is ultimately clear and easy to take in.

The same applies to the now touch-only centre screen, which has a slick rich finish and tactility, and also encompasses the climate-control display.

Along with banishing the dreaded mouse pad, kudos to Lexus for also installing physical switches or buttons for the most-used items – audio volume, temperature setting, and front and rear window demisting.

These and the simplified sub-screen menus for navigation, wireless telephony/audio streaming, vehicle diagnoses and vehicle settings amongst other features, is quickly second-nature in their accessibility and operation. And the sound system quality is great too.  

One of our very few complaints concerns the Apple CarPlay experience, which seems needlessly complicated to return to if you temporarily switch away from it to the NX’s native multimedia system. Confusing and distracting. 

Never mind. There are minivan levels of practicality at work here, from the superb and easily manipulated ventilation system to the seemingly endless storage options, that include bottle holder capability in the doors, a clever lid operation for the huge centre console and properly engineered cupholders.

Lovely lush materials of satisfying quality are further plus points.

We’re also fans of the NX’s electric door opening system with a failsafe handle, meaning you can grasp the door handle inside or out and a solenoid activated by a press in of a thumb releases the door quickly and naturally in a single action; it feels… upmarket and ergonomic once accustomed to.

Accessing the back seat is easy due to the latest model’s larger proportions. Much of the same applies out back as the front seat area in terms of quality of finish and attention to detail. Sculptured and enveloping backrests (adjustable for two reclining positions), a well-padded cushion and more-than-sufficient space for two burly adults or three smaller people means this NX is more family friendly than the swoopy exterior styling suggests.

We’re also happy to find large people-facing air vents, two USB and a 12V outlets, one-touch electric windows with that premium-car soft close mechanism, overhead LED lights, grab handles, centre armrest with cupholders, map storage behind both front seats, coat hooks and good lines of vision further enhance the appealing and comfortable back seat environment. It feels like a Lexus should.

Further back than that, after releasing the electric tailgate via either an interior button or exterior switch, you’ll find that the boot has a fairly high loading lip, but then offsets this with a long, flat floor with matching levels of appropriate-quality finishes. Another 12V plug and two bag hooks are included, along with ample lighting and tie-down hooks. There’s also a hidden deep storage compartment underneath the floor, due to the discontinuation of a spare wheel (due to runflat tyres, remember).

Capacity is rated at a fairly ordinary 520 litres, extending to 1411L with the split/fold backrests folded. You’d expect a remote actuation for the latter like Mazda wagons have had for decades, but none is found at this price point.

Note there is no solid cargo cover either, just a flexible/flimsy fabric item that’s foldable and easily stored.

Overall, though, despite of its base positioning within the NX hierarchy, the 250's interior experience is in keeping with the brand's image.

The IM6 measures 4904mm long, 1988mm wide and 1669mm tall, and it rides on a 2950mm wheelbase, with IM describing it as a "mid-large SUV", though I expect it will be classed as a medium SUV Australia.

That said, ICE and EV mid-size electric SUVs are not cut from the same cloth, with the latter making use of a flat floor to maximise space. And so it is with the IM6, where backseat room is pretty damn impressive. I’m 175cm, and I had no problem at all with legroom or headroom, plus the same plush seats from up there are in the back, too.

There are also air vents but no temperature controls, and while there are USB ports, there is no regular household-style plug in the cabin. 

The glass in the windows is laminated, while the roof is double glazed, which MG tells me is Australian summer-proof, but I guess we'll know for sure in a couple of months.

There’s no shortage of cargo room either. There’s a 32-litre frunk up front, and there’s 646 litres in the boot with the rear seats in place. They’re 60/40 split, and if you drop them, luggage space grows to 1621 litres.

The towing capacity is a braked 1500kg, too, but I don’t expect to see many of these towing a camper trailer around.

Premium play means more premium prices, and my IM6 Performance will set you back $80,990 on the road. That might have just sent your eyebrows skyward, but keep in mind it’s faster than some Ferraris, and is swimming with high-end tech, so the bang-for-buck factor is actually still pretty good.

There are cheaper ones, too. The single-motor Premium grade is $60,990 drive-away, albeit with less power and slower charging. Then there’s the Platinum, with a bigger battery and faster charging, which is $69,990

The Performance, though, gets everything IM has to give, including an 800-volt architecture, which means super-fast charging, as well as twin motors, brutal acceleration, a decent driving range and adaptive air suspension.

Elsewhere, you get LED lighting, a big and insulated glass roof, and 20-inch alloy wheels. Inside, there are thick and soft synthetic leather seats that are heated and cooled in both rows, a banging 20-speaker sound system, and wireless charging to pair with wireless Apple CarPlay and Android Auto.

There’s also 'active noise cancellation', and a seat-aware digital assistant which is about the best, and fastest, I’ve ever used. The IM6’s speaker system can locate where a voice is coming from, so any passenger can use the assistant. For example, if you’re in the backseat and say 'hey IM, lower my window', only your window opens. It’s a technology that I specifically remember the German brands crowing about not so long ago.

There’s also a 10.5-inch central touchscreen that controls much of the vast 26.3-inch screen that runs from in front of the driver to the centre of the cabin, as well as clever little magnets embedded in the dash in front of the driver, as well as in the back of the front seat headrests, that are designed to hold phones, iPads or other little accessories.

Also cool is the IM6’s self-parking tech, but there’s also a relatively useless crab walk function, which leans on the rear-wheel steering system to drive diagonally at slow speeds. I’m still not entirely sure when you’d use that one, to be honest.

Honestly, it’s a lot of stuff, and a lot of tech.

There are two ways of looking at this.

Yes, the NX 250 is powered by a variation of the same engine found in the humble base Camry Ascent in Australia at almost half the price. On the other hand, it’s a Toyota powertrain and everything that’s good and reliable and dependable about that. Which is not always the case with premium SUVs.

Dubbed Dynamic Force, which may imply forced-induction like a turbo or supercharger but there isn’t any, the 2487cc 2.5-litre naturally aspirated direct-injection D-4S twin-cam four-cylinder engine delivers 152kW of power at 6600rpm and 243Nm of torque at between 4000rpm to 5000rpm.

Drive is sent to the front wheels only, via an eight-speed torque-converter automatic. Tipping the scales at a pretty hefty 1705kg, it’s nonetheless the lightest NX, and manages a power-to-weight ratio of 89.1kW per tonne. That’s about the same as a GLC 200, which uses a 2.0-litre turbo petrol engine.

This is the real party trick of the IM6, because there’s a nuclear power plant under the metal somewhere. All up, the twin-motor setup produces a total 578kW and 802Nm, though I suspect you’re never accessing all the grunt all at once. Still, 100km/h zips by in 3.4 seconds, and the top speed is 239km/h. For the record, that’s exactly as fast the Ferrari Roma Spider I recently handed back, so yeah, it’s properly supercar quick.

Rated Euro6b, the NX 250 demands 95 RON premium unleaded petrol. Same as Camry, actually,

We recorded a decent 9.7 litres per 100km during our time using the NX 250 in city, urban and rural conditions, against the trip computer’s 9.5L/100km and the official combined average of just 6.9L/100km.

Note this may be so because there was a lot of fast back-road driving, as the engine loves a rev and there’s a palpable wave of power that comes on strongly between 5000rpm and 6500rpm. A bit like Mazda’s naturally-aspirated units, but just not as sonorous.

At 55 litres, the fuel tank will allow for up to 797km based on the combined average cycle between refills.

Also on board is a 100kWh Nickel-Cobalt-Magnesium battery that produces a WLTP driving range of 505kms. Pretty good.

Charging is strong, too. The high-tech platform allows for 396kW DC fast charging, which is faster than what is currently offered in Australia. The claim is 30-80 per cent charged in 15 minutes. There’s also an external vehicle-to-load (V2L) port.

The NX 250 truly is a tale of two cars.

Around town, it is utterly capable and benign. The 2.5-litre atmo four-pot petrol unit is a revvy, raucous sort of engine, pulling away strongly off the line, responding quickly to pressing down on the throttle, shuffling up through seven of the lower gears smoothly (top is a highway overdrive), and generally being an easy vehicle to drive.

About the only concern is how noisy the engine can become if you’re needing to accelerate hard, with a definite mechanical zing that gives the Lexus a bit of a hoon attitude. We’re also a little hesitant about using the Sport mode in built-up areas, as ratios are held on to whether up or down shifting, amplifying the loud nature of this powertrain.

Other aspects of the NX 250’s driveability around town rate highly: light yet linear steering, with a tight turning circle providing easy manoeuvrability and parking; firm yet still absorbent suspension, offering an appropriately isolating ride over most bad road surfaces; and an overall sense of sound engineering. It seems quieter than an equivalent RAV4, more importantly.

Which led us to initially conclude that, in an urban environment, you’d naturally pay the extra $3K for the NX 250 Hybrid, to eliminate that noisy engine when pushing down hard on the throttle. Easy.

However, then we ventured out on a long rural drive, a few couple of hundred kilometres from the big city. On country roads, the NX 250 really sparks up in a most compelling way.

Yes, the engine is still a bit rowdy, but as the revs rise and the needle edges near the 6800rpm red line, the Lexus just keeps on building up speed rapidly, providing an unexpectedly sporty edge. Above 5000rpm this thing still has plenty of oomph, relying on a deep well of power to really extend its legs.

It also makes sense to slot the auto lever into manual, and use the finely positioned paddle shifters. That’s when you’re most aware of the gearbox being a torque-converter auto, with defined and assertive selections. It’s a good way to feel involved in the experience too.

Actually, as a mechanical ensemble, it all comes together at speed; that light and easy steering remains relaxed yet reactive, weighing up nicely if you choose Sport. The handling maintains a fluid, connected feel, with ample levels of grip from the Bridgestone tyres.

It occurred to us that driving the NX 250 Hybrid out on rural backroads would deny the enthusiast of the base model’s lightness and agility, since the latter weighs hundreds of kilos less; the brakes are perfectly modulated instead of feeling vaguely mushy and/or trigger happy as with many electrified SUVs; and – even with the road noise being well-supressed – you’re far less aware that the atmo petrol engine is singing loudly at speed.

Plus, the ride out in the sticks, even on our craggy old test strip that would jar the bones of some other midsized SUVs, remains calm and comfortably firm. That’s real progress for the NX.

We’d appreciate a bit more nuance in the way the stability control kicks in (quite late) to catch the tail; while the driver-assist tech like the adaptive cruise control and lane-keep assist do their jobs admirably, the latter’s constant chiming can be annoying; and there's a fair amount of road-noise intrusion over coarse bitumen. Like most midsized luxury SUVs, actually. Still quieter than a RAV4, though.

No jarring faults then. Lexus has done its homework and fixed most of the things that annoyed or infuriated us about the previous generation version. Good work.

First things first, don't get too distracted by the word "performance" here. The IM6 doesn't act like a performance car, it feels bit too plush, and bit too digital, for that.

But that's not necessarily a bad thing. Performance cars are often loud, raucous and uncomfortable, and the IM6 is none of those things. Instead, those mountains of power and torque make silky, silent progress absolutely effortless, which feels pretty premium to me.

MG makes a big deal of how much work went into insulating the cabin from noise – with active noise cancellation joined by double-paned insulated glass – and it is a properly calming and quiet space.

Also strong is the suspension, with the adaptive air setup soaking up most bumps and bruises, but I found it can clang over really solid bumps, sounding like it's bouncing off a stopper. The steering is solid, too, with a nice weight, if not overly talkative in the feedback department, while the rear-wheel steering helps eat into the turning circle for tight three-point turns.

The downside, though, is that it all feels a little too digital, and like there's been a little too much overthinking gone into it. Having to push a button to see behind you in a hurry is bonkers (see my explanation in the Safety section below), and the secondary screen is more annoying than intuitive. And there were several bings or bongs I couldn't even identify. All of which interrupts the otherwise calming nature of the drive experience.

There is a long list of safety aids on the IM6, and I won't detail the lot here. But I will call out a couple of curious mentions.

As always, the driver distraction warning is annoying, but can be switched off. And MG also counts the IM platform, or what it calls a digital chassis, as part of the safety offering. It has its own digital brain that adapts the air suspension, the rear-wheel steering and the active safety kit on the fly.

The other curiosity is the weird way you see out the back. Rather than fit a digital rear-view mirror to counteract the almost non-existent rear vision, you instead push up on a little toggle on the steering wheel to bring up a live view of what's happening behind you on the central screen.

Since the beginning of 2021, Lexus offers a five-year, unlimited kilometre warranty with roadside assistance. It used to be four years.

Service intervals are at 12 months or 15,000km, whichever comes first.

The NX also includes three years and 45,000km of capped-price servicing, with each one costing $495 – and as we’ve noticed in the recent past, that is very highly competitive pricing for a luxury brand.

Plus, there’s also Lexus’ ‘Encore’ aftersales subscription program offering myriad offers and services.

The IM6 is covered by a five-year, unlimited-kilometre warranty, rather than MG’S 10-year term. Capped-price servicing is offered for the first five years, with your total bill just under $3000. The service intervals are 20,000kms or 12 months.
