Lexus NX450H+ vs MG HS

What's the difference?

The NX 450h+ Luxury combines high build quality and upmarket looks with plug-in hybrid convenience/performance/economy and numerous luxury appointments. It’s a competent all-rounder that's difficult to fault and clearly meets the needs of many prestige mid-size SUV buyers.

There are a few niggles with the latest MG HS, for example the annoying driver-attention monitoring and expensive maintenance costs. We’ve not had a full sample of its open-road performance yet either, which may prove more telling.

Yet the HS is shaping up to be one of the most successful product updates of recent years, second only to, I don’t know, the MG3? The family SUV is also backed by a 10-year warranty and, despite the drastic improvements, doesn’t cost a whole lot more than before.

The entry-level Vibe is our pick, there's no need to spend more. It features all manner of safety equipment and a quiet drive but with cloth upholstery that doesn't get all sticky and sweaty in the Australian climate.

The end of 2024 is the tipping point where MG goes from cheap and cheerful to a real headache for established players. Perhaps not for the strongest in the segment like the RAV4 and Nissan X-Trail, but the HS is now an easy car to recommend for a family looking for a spacious SUV that drives their dollar further. The hybrid will boost appeal further when it arrives next year.

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

The exterior is a sculptured blend of sharp creases and flowing curves which create a sporty and sophisticated appearance that clearly appeals to many buyers.

The interior looks and feels about as spacious and airy as you could realistically expect in a mid-sized SUV, which is enhanced with the roof open and sunshine pouring in.

The boldly contrasting two-tone grey and camel interior trim in our test vehicle adds to its visual appeal although we suspect such a bold colour choice could also be a stain magnet in everyday use, particularly for young families with lots of sticky kids’ stuff onboard.

Though the previous HS had shapely bodywork, the wheels sat too far in-board and the rear end looked awkward. It’s not the same story with the new model which is designed as a family SUV first, rather than a converted hatchback platform.

Part of the improved looks are better proportions. The new HS is 81mm longer, 14mm wider and rides on a 45mm longer wheelbase yet sits 21mm lower for a sleeker appearance.

The front end takes cues from the new MG3 and ZS design language with a broad grille and thin LED headlights. At the back, MG’s design team references the UK’s capital with ‘Shard’ lighting signatures that also appear in the alloy wheels.

It is still fairly anonymous, though perhaps that comes from a lack of familiarity with the brand. The painted wheel arch cladding and metallic-only paint give it a premium boost.

The biggest improvement is inside, where the HS takes plenty of inspiration from the excellent MG4 electric car with the hexagonal steering wheel (though here with perforated leather finishing), high-set controls and confident lines. It’s a welcome, modern change after the old car’s bloated cabin design.

There are soft-touch rubbery materials in all sorts of prominent places, including on the dash top, front and rear door cards as well as where the driver’s knees rest on the doors and transmission tunnel.

Its compact dimensions of 4660mm length, 1865mm width and 1660mm height make the usual driving chores in congested urban settings, particularly tight inner-city streets and parking spaces, much easier than a full-size SUV.

With its 2050kg kerb weight and 2540kg GVM, it has a load capacity of 490kg of which up to 75kg can be carried on the roof rails using approved racks.

While almost half a tonne of load capacity may seem ample, keep in mind that the combined weight of five large adults could reach that limit before you could start loading their luggage.

It’s also rated to tow up to 1000kg of braked trailer, which would be ideal for hauling small trailers with a recreational focus like fold-out campers, jet-skis, trail bikes etc. However, Lexus does not publish a GCM figure, so for weekend escapees we don’t know how much it can legally carry and tow at the same time.

There’s more than adequate space for the driver and front passenger, along with storage that includes a bottle-holder and bin in each door, overhead glasses holder and a single glove box.

The centre console has two cupholders and a deep box with padded lid that doubles as a comfy elbow rest. You’ll also find a quartet of USB ports, a 12V socket and wireless phone charging pad.

The rear bench seat is surprisingly accommodating for tall people, given I’m 186cm and when seated behind the driver’s seat set in my position I still have sufficient knee clearance and headroom.

However, with three up, those in the centre must compete for shoulder space plus have their feet either side of the transmission tunnel and knees together between the front seat backrests. So, three adults is okay for short trips but should be capped at two for longer drives.

Rear passenger storage includes a bottle-holder and bin in each door, pockets on both front seat backrests and two cupholders with the centre seat backrest folded forward. The rear of the centre console has adjustable air vents, rear seat heating controls, another 12V socket and a pair of USB ports.

The power tailgate can open by waving your foot under the rear bumper (useful when hands are full) to gain access to the rear luggage area, which provides numerous internal hooks for securing cargo straps or nets plus underfloor storage for the charging cables and more.

This luggage area offers up to 520 litres (more than half a cubic metre) of load volume with the rear seat upright. It expands into what is effectively a small van when the rear seat is folded flat, which can carry everything from a mountain bike to flatpack furniture.

There is nothing especially ground-breaking about the MG HS’s front cabin. The cupholders are medium-sized and the door bins have enough storage for a one-litre bottle, so this is no Skoda Karoq when it comes to clever cabin solutions.

Telling a tale of the HS’s Roewe RX5 base car’s earlier 2022 launch (and the staggering development speed of personal technology) the lack of USB-C charging ports is now frustrating with all USB ports regular old-school items. Apple CarPlay or Android Auto phone mirroring requires a cabled connection.

The centre multimedia screen is high resolution with day selectable light and dark modes. It was a little laggy to use MG’s software, however, especially when swiping across menu screens. 

There are four hard shortcut buttons beneath it that can jump to the home screen, activate the HS’s front and rear demister and turn the ventilation on and off.

To adjust the temperature you need to go into the touchscreen, though there is a persistent shortcut on the main menu.

A 12.3-inch digital cluster has several selectable info displays and can show navigation mapping and directions in Excite and Essence trims. 

The seats are comfortable and supportive and it's easy to find a good driving position thanks to power-adjust driver's seat and tilting/telescoping wheel adjustment. The front passenger does not get height adjust, though, and is set too high.

Where the extra size pays dividends is in the back seat which has ample room for passengers beyond 185cm, especially when it comes to leg space. The fold-out armrest is sturdy, too, with twin cupholders. Rear air vents are fitted to only the top-spec Essence.

For baby capsules or child seats the HS has ISOFIX anchors fitted to all three rear seats matched with a trio of top tether points.

The MG HS’s boot is about average for the class measuring 507 litres. It grows to 1484L with the 60:40 backrest folded. For reference, class leaders include the Toyota RAV4 (580L), Nissan X-Trail (585L) and Volkswagen Tiguan (up to 615L with rear seats slid forward). 

There are few amenities, with no 12-volt socket, only one (dim) boot light and no shopping bag hooks. The carpet isn’t bargain basement and the luggage cover is sturdy with additional separated storage compartments below the floor and netted cubbies off to the side. 

MG has also been smart in packaging a space saver spare tyre beneath the boot floor (and a cumbersome Styrofoam piece).

Shock horror, the new HS is 10 per cent more expensive than before… but that still makes it $33,990, drive-away, for the basic Vibe — easily undercutting established rivals from Honda, Mazda, Toyota and others. 

You get a lot for that extra $4000, too, right down to basic presentation. There’s no fridge-like solid white paint with all six hues either metallic or pearlescent for no extra cost. MG even offers the upper trims with the option of an eye-catching tan upholstery colour. 

The three-strong trim line-up starts with the Vibe: dusk-sensing LED headlights, 18-inch alloy wheels, adaptive cruise control, auto wipers, tyre pressure monitoring, a six-speaker sound system, nice cloth upholstery and six-way power adjust driver’s seat are standard.

The Excite sprinkles in 19-inch alloy wheels, perforated synthetic leather upholstery, navigation, fog lights and MG’s 'iSmart' connectivity system for a smart $36,990, drive-away.

The range-topping Essence gains a panoramic sunroof, rear privacy class, a power tailgate, front parking sensors, wireless phone charging, eight-speaker audio, 10-way power adjustable driver’s seat with memory, seat heating, dual-zone climate control, rear air vents and wireless phone charging for $40,990, on-the road. 

The short of it is that, although MG’s prices are up, even the basic Vibe is a more enticing proposition on price than the new Chery Tiggo 7 Pro Urban ($39,990, drive-away) and established Mazda CX-5 Maxx (currently on offer for $37,990, drive-away).

It also is much closer to the popular GWM Haval H6 ($31,990-$37,990, drive-away) — if only MG had brought ventilated seats to the flagship Essence then this mid-sizer would be (almost) sold on paper alone.

The sophisticated PHEV drivetrain with electronic AWD comprises a 2.5-litre four-cylinder petrol engine that delivers 136kW of power and 227Nm of torque to the front wheels through a Continuously Variable Transmission (CVT).

There’s also electric motors front and rear, fed by an 18.1kWh lithium-ion traction battery that can provide limited electric-only driving range.

The front electric motor, which assists with driving the front wheels through the CVT, produces 134kW/270Nm while a smaller one exclusively drives the rear wheels with 40kW/121Nm. Although the combined output from these three power sources is 310kW, Lexus claims a total system output of only 227kW to optimise efficiency and reliability.

The petrol engine and electric motor outputs are electronically synchronised and traction is continuously monitored to automatically vary the amount of power being sent to the front or rear wheels to optimise stability and traction in all conditions.

There’s also a choice of drive modes comprising 'Normal', 'Sport' and 'Eco' and paddles on the steering wheel allow manual shifting of the CVT 'ratios' for a more engaging drive, or to increase the regenerative braking effect (like using lower ratios on descents etc).

Several operational modes can also be selected including electric-only driving (we covered 60km on one full charge and 56km on another) and two modes of hybrid driving, plus battery charging while driving courtesy of the petrol engine which during our test charged the battery from near zero to 100 per cent in 56km.

There’s also external plug-in charging of course. At home we used the three-pin domestic wall socket compatible 10A charger/AC Type 2 cable supplied with the vehicle, which took about six hours (at a tiny 2.3kW) to charge from 35-100 per cent.

The new HS petrol has a 1.5-litre, turbo-petrol, four-cylinder engine that develops 125kW at 5000rpm and 275Nm from 3000-4000rpm, with those outputs up 6.0kW and 25Nm on the old car.

MG claims new engine features, including the variable geometry turbocharger, centre-mount variable valve timing and a lighter dual-mass flywheel, add up to a 30 per cent improvement in engine response.

More importantly, the insulation is excellent. You barely hear any unpleasant engine noises out on the road and although the four cylinder’s tone isn’t sexy at full-throttle, it is warm and pleasant enough.

The HS petrol is front-wheel drive only which may rule it out for some buyers, but there is a saving grace. The new seven-speed type dual-clutch transmission behaved itself impeccably on a brief first encounter taking in awkward hill starts and reverse manoeuvres. It’s a huge improvement over prior efforts and more refined than even a Hyundai or Kia dual-clutch.

MG claims a 0-100km/h acceleration time of 9.6 seconds, which is about right for entry-level versions of the HS’s typical rivals.

MG no longer offers a more powerful 2.0-litre turbo but a plug-in hybrid with a punchy 223kW and an all-new full-hybrid option will join the line-up in the first quarter of 2025, details of which are yet to be confirmed.

Lexus claims average combined consumption of only 1.3L/100km, achieved in ideal lab conditions which is largely irrelevant. When we stopped to refuel after 424km of real-world testing, which included our usual mix of suburban, city and highway driving and switching between the different modes (including 116km of electric-only driving), the dash display was showing 5.7L/100km.

That was close to our own figure of 5.4 calculated from fuel bowser and tripmeter readings, so based on our test consumption and depending on the mix of drive modes used, you could expect a realistic driving range of up to 1000km from its 55-litre tank which prefers 95RON premium petrol.

In the ADR combined (urban-extra urban) fuel efficiency cycle, the MG HS petrol is rated at 6.9L/100km, emitting 156 grams of CO2 per kilometre in the process. A 55-litre fuel tank gives the HS a theoretical driving range of around 800km.

We weren’t able to get a true read on the fuel consumption but the trip computer showed 8.1L/100km after an hour-long run. It lacks an idle start-stop system and requires 95 RON premium unleaded petrol.

The cabin is what you might call ‘cosy’ for tall people like me (186cm) but there’s still adequate room to find a comfortable driving position.

The ride quality is noticeably firm, which contributes to its sporty feel. The steering is nicely weighted with good response and braking is reassuringly strong.

Acceleration in full-electric and hybrid modes is brisk but not exceptional and about what you’d expect from this powertrain, which engages the rear electric motor for standing starts and other situations to ensure all-wheel drive traction is being deployed when you need it most.

We sampled the different drive modes, with 'Sport' providing a more engaging feel (particularly when manual shifting using the paddle shifters), 'Eco' producing a more subdued response to optimise range and the default 'Normal' providing a pleasant compromise.

Even so, despite its technical wizardry and generous choice of driver preferences, we reckon most daily driving owners would simply plug-in and charge each night, start off in electric-only mode and if needed continue in ‘Normal’ hybrid mode.

MG’s launch drive program was too brief to really get under the skin of the HS, which is a shame because the initial signs are extremely positive.

Compared to the old ZS, in which a gumnut hitting the roof was loud enough to distract you from your thoughts, the new car is packed with sound deadening for a vastly more premium experience.

The electronic power steering system has a natural ratio (2.6 turns lock-to-lock) and weighting in 'Comfort' and 'Sport' modes, which cannot be said for rivals such as the Chery Tiggo 7 and Haval H6.

This new HS rides nicely, too, with enough compliance from the suspension without sacrificing body control — at least around town. It has struts up from with a multi-link rear end which is not a given, even in this segment.

There were a few sharp-edged bumps that sent a shock through the body but that is to be expected on Sydney's awful roads. The new HS rides about as well as a Mazda CX-5 and believe us, that is a dramatic improvement.

Visibility out the front and sides are good as is the comfortable driving position, however I wasn’t able to move the driver’s side mirror far enough out for my liking. That’s a small blip in an otherwise strong first showing.

The MG HS has not yet been evaluated by an independent safety testing body such as ANCAP or Euro NCAP.

MG has fitted the new HS with seven airbags, including driver and passenger, front side, side curtain and a centre airbag.

The HS has a long list of active safety and driver assistance features, such as front and rear auto emergency braking with junction detection, lane-keep assist, blind-spot monitoring, adaptive cruise control with stop and go and driver-attention monitoring.

I can’t say all the aids are perfect but the adaptive cruise control and lane-keep assist systems were less intrusive than those in Chery and Haval products.

The regularly-beeping driver-attention monitoring remains a constant frustration as it does across almost every brand at the moment.

Comes standard with a five years/unlimited km warranty. Same applies to the lithium-ion traction battery, which is eligible for additional warranty coverage of up to five years (so 10 years in total) based on annual inspections.

Scheduled servicing is every 12 months/15,000km, whichever occurs first. Capped pricing, which applies to the first five scheduled services up to five years/75,000km, totals $3225 or an average of $645 per service.

MG has recently moved to a 10-year/250,000km new car warranty in Australia which covers the HS and is the longest non-conditional offer in the market.

GWM/Haval, Kia and SsangYong remain at seven years while Mitsubishi requires you to service the car at a main dealer for its 10-year guarantee.

This long warranty period should help allay concerns for new MG buyers that the brand stands behind its products.

Less impressive is the cost of maintenance, which adds up to $2354 over five years/75,000km with a particularly steep $936 service at the four-year mark. There’s a big $1647 service at 120,000km, too.
