MG Mg7 vs Lexus NX450H+

What's the difference?

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.

The Lexus NX450h+ F Sport is a gorgeous mid-size SUV that combines great specs and a fairly efficient plug-in hybrid powertrain. It’s a comfortable and easy ride which should appeal to a wide range of driving styles. It also looks good parked at the kerbside of a city street and with it ticking most of the boxes, it may become your new best friend.

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.

The NX simple looks like a scaled-down version of its larger RX cousin, so if you like that you’ll like what the NX.

It looks sweeter, though, with its smaller proportions being only 4660mm long and 1670mm high but there’s enough sharp pleating in the panelling and rear LED lights to give it a sporty edge. It’s a design that should appeal to a wide range of people.

The interior helps the NX compete against some of its flashier rivals, but the BMW X3's interior beats it hands down with the wow factor. Still, the dual-toned leather upholstery and fabrics of our test model scream understated luxury.

The perforated leather of the seats is supple underhand, but even the robust synthetic leather on the backs of the seats and some door panelling feels like the real stuff most of the time.

The dashboard components – like the air vents, displays and accents – are well integrated and seem well-built. The cockpit is intimate and plush overall, and it always reminds you that you're in the cabin of a luxury vehicle.

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.

The cabin of the NX is spacious where it needs to be for four adults to be comfortable on a longer journey, and features enough equipment to satisfy most.

Access is best at the front because of the wider door apertures and while still easy enough to get in and out of from the back, the rear wheel arch cuts into the aperture a bit.

The front seats are very comfortable with thick padding, tall side bolsters that lock you into place in a turn as well as heating and cooling functions.

The back seats are almost as comfortable as the front! However, the outboard seats offer the best under-thigh support. It is a shame that they miss out on heat functions for its grade level, though.

Storage is fairly good for the class, with lots of small item cubbies up front like a sunglasses holder, a mini drawer next to the drivers' knee and a dedicated phone holder and two cupholders. The large glove box (that can hold more than just a manual) and mid-size middle console shoulder most of the storage burden, though.

In the back you get a couple of map pockets, small storage bins and two cupholders. which is most than enough for this size of SUV.

The boot offers an impressive 520L of capacity and a level loading space makes it an easy car to slide larger gear in and out of. The little storage compartment under the floor is handy for charging cables and the hands-free powered tailgate is always handy to have.

The technology is a nice mix of easy-to-use and high-end with a responsive touchscreen on the 14-inch multimedia display. The system has built-in sat nav, wireless Apple CarPlay and Android Auto. The CarPlay was simple to set up and has maintained a steady connection with my iPhone this week.

Charging options are decent with two USB-C ports and a 12-volt socket per row, as well as a wireless charging pad up front.

With a price hike of almost $6K, our flagship NX sits at $95,900 before on-road costs, but it's still slightly more affordable than its top-grade plug-in hybrid rivals.

The Volvo XC60 Ultra is priced from $101,390 and the outgoing BMW X3 xDrive30e sits at $102,500.

In the flagship variant, the standard features list is well-rounded to include both practical and luxury equipment. There are electric front seats with heating and cooling, an F Sport steering wheel with heating and touch controls, a sunroof, rear privacy glass, and a power-adjustable steering column.

Other items include a powered tailgate with a kick-to-open function, dual-zone climate control with a humidity sensor, parking assist, keyless entry/start, a digital key, Lexus Connected services app, a digital rearview mirror and 20-inch alloy wheels.

The technology looks gorgeous with the 14-inch touchscreen multimedia display taking centre stage with built-in satellite navigation, Bluetooth and wireless Apple CarPlay and Android Auto.

You also get a 10-speaker Lexus premium sound system, which has AM/FM radio, MP3 and WMA (Windows Media Audio) compatibility. There are four USB-C ports (2/2), a 12-volt socket and a wireless charging pad.

So while our test model misses out on some of the items you might expect to see for a top-model grade – like three-zone climate control and heated rear outboard seats – it still feels well-specified.

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.

The NX450h+ F Sport is the first attempt at a plug-in hybrid powertrain for Lexus. It pairs a 2.5-litre four-cylinder petrol engine with two electric motors, one located at each end of the car for all-wheel drive. Together they produce up to 227kW of power, but Lexus doesn’t quote the combined torque figure (cheeky).

The flagship model can do a 0-100km/h sprint in 6.3 seconds and features a smooth continuously variable transmission.

Overall, it moves quickly and the shift between the electric and engine components is barely noticeable.

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.

The flagship NX has a smallish 18.1kWh lithium-ion battery and a Type 2 charging port but no CCS enhancement, which means you can’t hook it up to a fast DC charger.

On a standard AC 240-volt domestic plug port, you can charge this from 0-100% in around 7hrs 30mins. You get a great electric-only NEDC-rated driving range of up to 87km and that means you really only have to charge it every other day, which I appreciated. 

The official combined fuel cycle usage is 1.3L/100km, but you won’t really see that in the real world. After doing some longer trips mixed in with city slicking, my average real-world usage popped out at 6.5L/100km, and I averaged 20.2kWh/100km when in pure EV mode. They’re not the best hybrid figures I’ve seen for the class, but they're not too bad either.

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.

This NX feels like it has lots of power in reserve when you put your foot down and never struggles going up big hills. When it’s in pure EV mode, it’s very quiet but there’s no big fanfare when this kicks over to the traditional engine. You barely notice it until you’re on the open road travelling at higher speeds, and that’s when the engine starts to sound more growly like its non-hybrid siblings.

The steering is forgiving without feeling too light and around town, the NX is nimble and sure of itself. The suspension is on the firmer side, so you’ll hear and feel the bigger bumps, but it never feels rough.

Visibility is decent with the largish windows, and the pillars that aren’t too wide from my driving position. I do like having the digital rearview mirror, though, because when you have a big car seat or tall adult in the back seat, the vision back there is hindered.

It’s pretty hard to find a modern car that’s terrible to park, especially in the mid-size SUV segment, and the NX is no different. Even in a small car space, you still have good clearance around you, which hopefully translates to less dings from neighbouring cars!

The 360-degree view camera system is top notch with its quality, and I like that the car disappears and you can see the ground underneath.

The NX comes with a maximum five-star ANCAP safety rating from testing done in 2022 and scored very highly across its individual assessment scores; 91 per cent for adult protection, 89 per cent for child protection, 83 per cent for vulnerable road user, and 92 per cent for its safety assist systems.

Eight airbags are standard which includes a front centre airbag and driver's knee airbag. 

Other safety equipment includes emergency steering assist, blind-spot monitoring, lane departure alert, lane-keeping aid, emergency lane keeping, traffic sign recognition, safe exit assist, rear cross-traffic alert, LED daytime running lights, LED cornering lights, tyre pressure monitoring, and an emergency call button.

The only safety item which can feel intrusive when driving is the adaptive cruise control as it has a feature that scans for bends in the road and will slow the car down in anticipation of them. On paper, this isn’t a bad thing but in practice, it was sporadic when it activated and sometimes slowed the car dramatically on bends you wouldn’t even call bends!

AEB with car, pedestrian, cyclist, motorcyclist, backover and intersection turning assist is standard and operates from 5.0 - 80km/h (up to 180km/h for car detection).

There are two ISOFIX child seat mounts and three top-tether anchor points in the rear row. The seat isn't wide enough to accommodate three child seats side by side, so two will fit best.

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.

The NX is offered with a five-year/unlimited-kilometre warranty, which is on par with its European rivals.

It comes with a five-year capped price servicing program, where services are competitively priced at $595 each.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
