Lexus LX450D vs MG Mg7

What's the difference?

If you're in the market for the best-of-the-best SUV wagon, then you could do a lot of worse than get in a LX 450d. It looks good, is packed with standard features and is supremely comfortable. The 450d also has an suite of safety tech worthy of the hefty price-tag and it works well as a daily driver and has plenty of touring potential, even though we doubt it'll ever get anywhere near achieving those claimed fuel-consumption figures with real-world usage. Sure, you could instead climb in a second-hand, well-looked-after, never-been-off-road LandCruiser 200 Series and spend the money you save, by not buying this new Lexus, on aftermarket and camping gear, camping fees and also hiring a team of four people to follow you on mopeds everywhere and constantly tell you what a great driver you are – but that's not the point with vehicles of this ilk. They may not be aimed at hard-core off-roading buyers, but they are cushy, classy, and cityified – and, in that respect, they're incredibly well-built for purpose.

In a world obsessed with SUVs and electric powertrains, a mid-size petrol sedan almost feels rebellious. But the MG7 kind of is. A sleek fastback with a turbocharged engine, a sporty edge and a price that makes you look twice - it’s a compelling combination. There are some drawbacks for families in efficiency and back-seat practicality but it's not a bad offering for those wanting something a bit more fun than an SUV.

It has that signature Lexus jagged space-age grille, chunky shoulders and beefy back end that suit a luxury SUV dreamed up by folks craving a significant presence and plenty of attention for their product.

Bulky side-steps, an upswept raked profile, scalloped side panels and moon roof all top what is a cool combination of eye-friendly design factors. It's a slick mix of low-level cool and high-end style.

Take a look for yourself and make up your own mind whether you like it or not.

The MG7 is genuinely good looking. The fastback roofline gives it a sleek silhouette, and there’s a confidence to the way it carries itself.

The blacked-out badging, quad exhaust outlets, 19-inch Michelin tyres and red brake calipers all lean into that sporty brief. It looks fast standing still. The frameless doors are a nice touch, and the retractable rear spoiler adds a bit of theatre and fun.

Inside, the cabin follows through on that upmarket intent. Deep burgundy leather and synthetic suede are used generously throughout, giving it a sumptuous feel. Although, my husband joked that he wouldn't be able to drive it during State of Origin... sorry, Queenslanders!

There’s less reliance on piano black trim, which I appreciate as it scuffs easily, and most surfaces look well-finished. The integrated headrests up front give the illusion of proper sports seats but I do wonder if the interior would pop half as well if it was finished in the optional black.

The dashboard is dominated by a wide digital display incorporating a 10.25-inch instrument cluster and a 12.3-inch media screen. The panoramic sunroof helps keep things light and airy, and while there aren’t many physical buttons or dials, which is usually a gripe of mine, the overall execution feels cohesive and premium for the price point.

It certainly feels like Lexus designers and engineers have maximised every last millimetre of interior space; there is stacks of room inside with plenty of real-world usable storage spaces, including cup-holders, door pockets and spots for keys, phones and other stuff.

The heated steering wheel, stylish analogue clock, wireless charger, Lexus climate concierge (coordinating all four-zone temperature controls), cavernous centre-console cooler box, and rear-seat entertainment system are all nice touches but pretty much assumed at price-points lower than this one.

The 12.3-inch high-definition media touchscreen is clear and bright and easy to operate, but the Remote Touch Interface, the control near the shifter, is very annoying to use. The toggle/selector is too sensitive, skipping past your actual choice over and over again, while you try to manipulate it just so, so it lands on the option you wanted.

The second-row seating is plush and the seat sections are easily slid forward and tilted.

Lexus claims the 450d offers 909 litres of cargo space if there are five occupants; and 1431 litres if there are only two occupants. If you have some casual weekend touring in mind, with a spot of camping, then this Lexus should cope with your gear, no worries.

Up front is where the MG7 feels most generous. The electrically adjustable front seats are comfortable and supportive for daily driving, although extendable under-thigh support would help reduce fatigue on longer trips. You do get heating for both the seats and the steering wheel but having to dive into the media menu to activate them is annoying.

In the second row, legroom is respectable for a mid-size sedan. Headroom, however, is tighter thanks to the fastback roofline and panoramic sunroof. Tall teenagers won't feel like they can sprawl out but younger kids will be fine. The second row features two ISOFIX child seat mounts and three top-tether anchor points but two child seats will fit best. Bending down to buckle in a child will remind your back why SUVs became all the rage, but it's certainly doable.

The seats in the second row are thickly padded and comfortable, and the fold-down armrest sits at a good height to lean on. Amenities aren’t especially extensive given there’s only one grade available, but you do get a couple of cupholders, map pockets, directional air vents and two USB-C ports.

Storage in the front row is about what you’d expect for a car of this size. There’s a decent glove box, a shallow middle console, large door bins and some handy little nooks near your knee. A sunglasses holder and a dedicated phone cradle with wireless charging round things out nicely. The wireless charger can lag a little in topping up your battery, and it's quick to overheat your phone - added ventilation would be a big help here. However, there’s also a 12-volt socket and two USB-C ports if you prefer a cable.

The media system itself is responsive and largely intuitive, although the touchpad-style controls on the dash feel slightly back-to-front in use. On the plus side, it’s very easy to flick into Sport mode and open up the exhaust using the cluster controls, which adds a bit of fun to the daily drive.

The boot offers 375 litres of capacity, which is on the smaller side for the segment. Comparatively, the Sonata N Line offers 480L, the Skoda Sportline 600L and the Camry 524L. That said, it’s been perfectly usable for grocery runs and the odd road trip this week. You do need to load bulkier items further back toward the seats to work around the sloping fastback design. A powered tailgate adds convenience, and there’s a temporary spare tyre underneath, which I always prefer to a repair kit.

For now, the MG7 is offered in a single grade, the Essence, priced from $44,990 before on-road costs.

That positions it just above the Skoda Octavia Sportline, which starts from $44,490 MSRP, although the Skoda doesn’t match the MG7 feature for feature. In terms of features and styling, it’s closer to the Hyundai Sonata N Line, which opens at $56,500 MSRP. And then there’s the segment darling, the Toyota Camry SL, from $53,990 MSRP, happily flexing its hybrid efficiency credentials.

On price alone, the MG7 looks competitive. On specification, it starts to look like a bit of a statement. You get leather and synthetic suede upholstery, heated and electrically adjustable front seats, memory function for the driver’s seat, a heated steering wheel, a panoramic sunroof and 19-inch Michelin tyres.

Technology feels well thought out and a large centre display houses a 12.3-inch media system, paired with a 10.25-inch digital instrument cluster that appears larger than it is thanks to the integrated touch controls. There’s wired and wireless Apple CarPlay and Android Auto, built-in satellite navigation, 256-colour ambient lighting and a 14-speaker Bose sound system.

Practicality hasn’t been overlooked either. A powered tailgate, temporary space saver spare wheel, dual-zone climate control, acoustic door glass, rain-sensing wipers and a 360-degree camera system round out the package.

The Lexus LX 450d has the LandCruiser's 4.5-litre twin-turbo direct-injection V8 engine, producing 200kW@3600rpm and 650Nm@1600-2800rpm. All of that power and torque arrives evenly and smoothly, helped no end by a slick six-speed sequential-shift transmission.

It has a full-time 4WD system, dual-range transfer case and off-road tech that includes multi-terrain anti-skid brakes, crawl control and a four-camera multi-terrain monitoring system with back guide and panoramic view. 

The MG7 has a 2.0L, four-cylinder turbo-petrol engine producing up to 170kW of power and 380Nm of torque. That’s pretty gusty compared to its nearest rivals, although the Sonata N Line still beats it with its 213kW/422Nm outputs. The Hyundai is more of a dedicated sports model. Still, with these outputs the MG7 manages a 0 -100km/h sprint in a swift 6.5-seconds!

Power is delivered to the front wheels and the nine-speed auto transmission punches through its gears relatively smoothly. You can also flip it into Sport mode, where gear changes become more pronounced.

Overall, the whole setup creates an engaging on-road experience without lulling you into any false pretences. The MG7 is not a racer, even though it looks like one, but it holds its own.

Lexus claims the LX 450d will achieve a 9.5L/100km figure from combined-cycle driving (that's 4.9L/100km more frugal than the LX 570 is capable of). Lexus reckons, based on that figure, that the diesel LX has a potential range of almost 1000km on a full tank (93 litres) of fuel.

We recorded 12.7L/100km during daily driving (city and suburbs) and 13.5L/100km with some light off-roading thrown into the drive mix.

The MG7 has a claimed combined fuel consumption figure of 8.0L/100km. With its 65-litre fuel tank, that equates to a theoretical driving range of up to 812km.

That places it broadly in line with the Hyundai Sonata N Line, which claims 8.1L/100km, although the Hyundai delivers stronger engine outputs. The Skoda Octavia Sportline is notably more frugal at 6.1L/100km, while the Toyota Camry SL continues to dominate the efficiency conversation with its 4.0L/100km hybrid figure.

In real-world driving, expect that 8.0L/100km claim to creep up. Even after a week consisting mostly of longer highway stretches, my trip computer was sitting at 8.6L/100km. That’s not wildly unexpected for a turbo-petrol engine, and it’s hardly alarming, but efficiency is a major consideration for families. Against hybrid rivals, it doesn’t win that particular argument.

Combined CO2 (ADR 81/02) emissions sit at 183g/km, which is comparative to the Hyundai Sonata N Line but not as low as its other rivals.

MG recommends a minimum 95 RON unleaded petrol to be used.

It’s supremely comfortable and very quiet, wth that customary cocoon-like enclosed sensation that you only ever truly get in a vehicle this far away from cheap.

The 450d is 5080mm long, 1980mm wide and 1865mm high. It has a 11.8m turning circle. It has an official kerb weight listed as between 2510kg and 2740kg.

For something with so many kegs onboard, it’s capable of punching off the mark with a respectable bit of pace; handy for city-street bursts to slip through traffic gaps.

It never feels cumbersome; it actually feels quite light on its toes. In fact this Lexus tends to be more than a little bit floaty at times. You can select different suspension settings – comfort, normal or sport – to suit your preference.

Visibility is generous all-round with clear sightlines in all directions; besides, the reversing monitor with 360-degree view helps if your views are hindered.

Steering is generally active but it does exhibit quite a lot of under-steer on twisting country roads. It has paddle-shifters if you’re that inclined.

The LX 450d rides on 20-inch alloys and 20-inch Dunlop Grandtrak PT2As (285/50F20 112V) – a combination which is fine for bitumen-based outings, but we’d ditch it for rubber with more sidewall to allow for greater freedom to adjust tyre pressures to suit rough terrain.

Power delivery in the MG7 is smooth and responsive, and it doesn’t take long to feel confident with the turbo-petrol engine. For a bit of extra fun, flick it into Sport mode and open the exhaust; gear changes become more pronounced, and the engine note gets noticeably throatier. It’s not a performance sedan, but it’s definitely engaging on the road.

Handling is another highlight. The steering is responsive and firms up depending on your selected drive mode, and the low-slung stance helps the car feel surprisingly nimble in corners. That said, it’s not always surefooted when accelerating out of tight bends, which reminds you that the MG7 is sporty but not track-focused.

Visibility is adequate but not perfect. The thicker pillars, lower roofline, and relatively small windows do make the cabin feel a touch enclosed, and there’s some road noise, which is enough to remind you it’s not a luxury saloon, but it never becomes intrusive.

The MG7 feels agile in tighter spaces, and the 360-degree camera system is high-quality. Parking is straightforward, which frazzled parents will appreciate.

The MG7 has a maximum five-star ANCAP safety rating from testing done in 2025 and scored well across its individual criteria with 88 per cent for its adult protection, 85 per cent for child protection, 80 per cent for vulnerable road user and 81 per cent for its safety assist.

Passive safety items include seven airbags including a front centre airbag and curtain airbags covering both rows. Families will like that there are two ISOFIX child seat mounts and three top-tether anchor points but realistically, two child seats will fit best. There are also powered locks for the rear windows and intelligent seatbelt reminders for all five seats. Parking is easy with the rear parking sensors and 360-degree view camera system.

Active safety includes forward and rear collision warning, lane keeping aids, lane departure warning and prevention, blind-spot detection, side exit assist and a relatively unobtrusive driver monitoring system.

Other highlights include emergency lane keeping, which will activate when there’s no response from the driver and the rear cross-traffic alert also gets assisted braking. The adaptive cruise control is fairly well-calibrated and it’s a bonus having the emergency call functionality, although it seems to connect to an MG service line, rather than directly with emergency services. And you have to select which country you’re in before it activates, which might not be a delay you want when you really need it!

There’s autonomous emergency braking with car, pedestrian and motorcyclist detection and it's operational from 4.0 – 85km/h and up to 150km/h for car detection but it is more typical to see that top figure closer to 180km/h.

Warranty is 4 yrs/100,000km. Service intervals with indicative pricing (exc GST) are: six months/10,000km: complimentary; 12 months/20,000km: $535.56; 18 months/30,000km: $598.11; 24 months/40,000km: $800.32; 30 months/50,000km: $502.44; 36 months/60,000km: $676.23.

MG backs the MG7 with a seven-year, unlimited-kilometre warranty. If you service exclusively through MG service centres, that coverage can be extended to 10 years or up to 250,000km, which makes it one of the more generous warranty offerings currently available.

At the time of this review, servicing intervals and service prices haven't been set for the MG7. It's fairly easy to secure servicing for an MG, as they have around 90 service centres nationwide at the moment.
