MG ZST vs Lexus Rx450H+

What's the difference?

Will the MG ZST Essence fit a small family? Absolutely, and all but the middle seat passenger will be comfortable but there are areas open for improvement. Like it's safety, laggy tech and adding a few extra items in the back seat.

Yet, it still offers a good host of features and an attractive package for a reasonable price tag. Unfortunately, my son missed having the basic amenities but did like the sun roof.

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

Being the newer and shinier version of the ZS, the ZST presents as a nice little package with its full suite of LED exterior lights, shiny chrome accents and its well-shaped body.

The front is distinctively different from its design muse with a darkened grille, and redesigned fog lights that feature new air intake vents. Other highlights include the 17-inch two-tone alloy wheels with sporty red brake calipers lurking behind them.

The interior is pleasant with a massive sunroof creating a light-filled space and giving the illusion that the cabin is larger than it is.

The synthetic leather upholstery and trims seem robust and perfect for families, but also feel quite plasticky under hand. The red badge embossing on the headrests is lovely, though.

The dashboard is well-proportioned and headlined by an upgraded 10.1-inch touchscreen multimedia system and fully digital instrument cluster.

The gearshift feels a tad too skinny and tall for the general aesthetic but the circular air-vents add some cute personality.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

Practicality is hurt by a lack of individual storage options and a back seat that has only two USB-A ports for its amenities.

The cabin space is spacious, though, and both rows have a decent amount of leg- and headroom despite the massive sunroof.

The steering wheel features height but not reach adjustment and to accommodate I have to sit much closer to the wheel than normal thanks to my poor little T-Rex arms.

Individual storage is the best up front with a small middle console and glove box, two cupholders and two drink bottle holders. The doors also feature large storage bins, which is great to keep the cockpit feeling neat.

The rear row gets two map pockets and a small storage bin in each door. There is also a (very) shallow storage nook at the back of the middle console… think a packet of gum or small wallet size.

My seven-year old isn't as comfortable in the rear because it lacks directional air vents, reading lights and a fold-down armrest. All items which will hinder an adult's comfort, too.

The boot space is a good size at 359L but you can bump it to 1187L with the rear seats folded, the backrest featuring a 60/40 split.

The height of the floor is adjustable and when set in the lowest position creates a deep well to tuck larger items, like luggage, into.

The hard cargo cover can be awkward to shift around or store but is otherwise out of the way when it counts.

Other amenities accentuate the premium-feeling the Essence is going for with the heated front seats and electric drivers seat offering well-padded comfort but on longer journeys, I miss having adjustable lumbar support.

The rear seats aren't as comfortable as the front only because the synthetic leather feels slippery, which is accentuated when you hit corners!

In terms of technology, you get two USB-A ports in each row but the front also gets a 12-volt port. You miss out on fast and wireless charging options.

The multimedia system looks great but can be sluggish to respond and the apps can be slow to load but I like the built-in satellite navigation.

The upgraded sound system has six speakers instead of four but the sound quality is a bit tinny with music and calls.

It was simple to connect to the wired Apple CarPlay. It also has Android Auto, Bluetooth connectivity and AM/FM radio.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

The Essence variant has a 1.3-litre, three-cylinder turbo-petrol engine with a maximum power output of 115kW and 230Nm of torque.

It's a front-wheel drive and features a six-speed auto transmission. Overall, it has enough power to keep up with traffic on the open road but you have to be firm with the accelerator to keep your speed consistent.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

The official combined cycle fuel figure is 7.3L/100km and my real-world average came in at 7.7L. That is after a good mix of urban and open-road driving, so the usage is good.

Based on the combined fuel cycle and the relatively small 45L fuel tank, expect a driving range of around 616km.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

The ZST Essence has an okay amount of power relative to the car's small size.

It's an adequate cruiser when I ferry just my husband and son around, but feels a full load of luggage and people.

The steering is responsive and it's an easy car to manoeuvre in tight car parks or city streets, which is great. The visibility is pretty good despite the chunkier pillars and you feel confident when checking your blind-spots.

While the suspension is fairly forgiving and ride comfort is decent, you will still notice the bumps, especially when seated in the back.

The cabin suffers from some wind and road noise and at higher speeds we had to find we raise our voices a bit to be heard. Around town, you don't notice it.

This is just a personal preference but the brake and accelerator pedals are skinnier and more centrally positioned than I prefer. You get used to it, though.

The ZST is pretty easy to park and it's great that you have a 360-degree camera system but the image quality can be grainy. You get rear parking sensors, too, but miss out on ones at the front.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

The ZST Essence comes with a seven-year/unlimited km warranty, which is on par with coverage offered by a growing number of its rivals.

There is a seven-year or up to 70,000km servicing program for a total cost of $2339 or an average of $334 per service, which is very competitive for the class.

Servicing intervals are at every 12 months or 10,000km, whichever occurs first, but could be annoying if you travel a lot.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
