MG Mg7 vs Genesis G80

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.

Overall, then, the flagship G80 tries to be docile Clark Kent and the amazing Superman in one. As such, it stretches itself trying to be both a luxury GT and high-functioning sports sedan.

But while it doesn’t quite achieve either perfectly the Genesis gets near enough for most – especially at its exceptional price point.

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.

Australia never saw the original 'BH'-series Genesis, which was created primarily with US buyers in mind to be a 5 Series alternative at a 3 Series price, complete with rear-wheel drive and advanced chassis dynamics.

Hyundai spun the series off as a stand-alone brand in the mid-2010s within the second-gen 'DH' Genesis’ run (that did include Australia) from 2015, which is when the G80 badge arrived, while the 'RG3' redesign you see here launched in 2020.

What you’re seeing here, then, is a facelift of a half-decade-old design, and doesn’t it give off Bentley vibes? From that blocky nose with its latticed grille to the sleek profile, the five-metre long by two-metre wide G80 passes for a Continental GT wannabe. Particularly in SL guise. And a convincing one at that.

When it comes to the interior, look around. A 27-inch OLED touchscreen takes in the crisp digital instrumentation and slick multimedia displays.

We like the configurable widgets that come complete with pictures for instant recognition, and the fact that Genesis decided to put an equally-user-friendly climate-control screen below, so eyes never need to leave the road once you quickly learn where all the switchgear is.

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.

Size may not be everything, some say, but it sure says a lot when a medium-sized luxury sedan is long enough to swing it with some large Germans. And in this case, the impressive dimensions are enhanced by a three-metre-plus wheelbase.

Behind the soft-close doors, you’re met with a cabin defined by the luxury of space and isolation from the outside world – just what you’d expect from a full-sized flagship sedan. There’s room to stretch in all five seats.

Plus, in the SL, the seats and chunky steering wheel silently whirr out of the way for easier entry and egress, before sliding back to their previous-memory positions.

The front seats are among the best we’ve experienced in a long time, holding and caressing in all the right places. Switching drive modes increases bolstering and/or support, whilst longer thighs will appreciate the extendable ottoman feature. Hot/cold control and a prodding massage function further enhances the users’ pleasure.

As in all Hyundai products the digital instrumentation and media touchscreen are paragons of simplicity and clarity.

Actual knobs for audio, tuning, fan and temperature controls flank these, along with buttons for 'Home', 'Menu', 'Driving Modes', 'Cameras' and parking sensors.

So thoughtful, so easy. Even vision isn’t too bad, aided of course by the surround-views available. This is quite an unintimidating vehicle to judge when parking despite its length.

Issues? The gear selector is the circular variety Jaguar debuted with the original XF during the late 2000s and is a bit clumsy to use; sited in prime console real estate, the cupholder lid is set-up for left-hand drive, meaning it provides a (minor) obstacle for the driver when open; the test car’s carbon-fibre-look trim won’t be to everybody’s taste and there’s no walk-to/away automatic central locking.

Meanwhile, the rear seat is in the spirit of a true limo.

Wide doors allow for easy entry/egress, revealing impressive levels of space for shoulders, hips, knees and feet (though headroom might be a mite tight for taller dos due to the sunroof). The left-side rear occupant can re-position the seat in front automatically to boost legroom even more.

Airliner premium-economy class-style backrest reclination is included. And you can sink yourself or your loose digits into the tactile and aromatic bliss of the perforated Nappa leather, thick pile carpet, suede trimmed pillars and ceiling and quality textures, further upping the luxury ante.

The large folding armrest facilitates access to heating/ventilation, audio, a sunblind, cupholders, phone chargers, USB-C ports and hidden storage.

The fortunate rear-seat passengers also face air vents and a separate climate control panel from the front-seat riders. So decadent. This was clearly designed for chauffer opulence and it shows. Very difficult to fault.

But further back, it isn’t so bountiful. Literally.

The pleasingly plush boot measures in at a smallish 424 litres, and that’s almost 100L down on a 520i’s. And while it comes with a ski or 'Bunnings port', simple folding backrests would have been more practical, particularly for car reviewers who occasionally need to transport their bicycle.

Oh well, that’s what SUVs are for.

The space-saver spare, in lieu of the hated tyre repair kit, is welcome, though. Thank you.

That HSV Grange analogy is pretty close to what the G80 3.5T AWD SL from $121,200 (all prices are before on-road costs) represents, and not just in dimensions and performance.

Adjusted for inflation, a 2015 Grange from $86,990 would equate to about $115,300 today, which nestles in neatly between the ‘base’ G80 2.5T rear-driver from $104,200 and 3.5T AWD SL.

And, like the big Holdens and Fords of yesteryear, the Genesis annihilates the German luxury sedan triumvirate for value for money as well as bang for your buck, when you consider what the competition is at its price point: Audi A6 45 TFSI quattro S Line from $122,415, BMW 520i from $114,900 and Mercedes-Benz E200 from $117,900.

Nowadays, even the entry-level Euro grades are pretty well specified, but all have 2.0-litre, four-cylinder, turbo-petrol engines of between 150kW and 180kW outputs and two-wheel drive, against the Genesis’ 279kW 3.5-litre V6 twin-turbo and AWD.

And then there’s the SL equipment levels, that includes everything you’d expect from a machine that is built like a Lexus, behaves like a BMW and wants to be as bourgeois as an S-Class Benz, with powered, electric and wireless everything.

It’s easier to list what’s missing: namely, walk-away door locking.

Still, listing some of the standout features is editorially required, so the SL’s lucky occupants can indulge in a heated front console armrest complete with UV-C sanitisation, a real-time concierge service with a five-year subscription included, a fingerprint recognition system for extra security (freeing society from a key!), a powered rear-window shade and the quietness that active noise-cancellation brings. And all are new with the MY25 facelift.

More opulence comes in the form of Nappa quilted leather upholstery, surround-view monitors, 18-way powered/heated/vented/memory front seats with massaging and ottoman extenders, powered reclining/vented/heated rear outboard seats with (manual) sun-blinds, tri-zone climate functionality with rear-seat controls, front and rear wireless smartphone chargers, 18-speaker Bang & Olufsen audio (with epic sound), soft-close doors, suede headlining, a panoramic sunroof with powered blind, solar-controlled glass, a powered boot lid with valet mode and remote-control parking.

We are pretty sure you won’t find this combination of gear in your entry-level German sedans at the 3.5T’s price point.

Genesis has also crammed in as much active and passive safety as possible. More on that in detail later on.

Note that there is also an all-electric G80 Signature Electrified AWD version from $155,000, making it the series’ true flagship.

Successive federal governments in Australia with their Luxury Car Tax have made this sort of vehicle a questionable value proposition as it balloons their prices, but within the context of what else is available, the G80 makes for a brave and bold alternative to formidable yet predictable alternatives.

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.

As the alphanumerics suggest, the G80 3.5T AWD is powered by a 3.5-litre twin-turbo V6 petrol engine, producing a hefty 279kW of power at 5800rpm and 530Nm of torque between 1300-4500rpm.

Tipping the scales at 2095kg (kerb), the SL’s power-to-weight ratio is 133kW/tonne.

Drive is sent to all four wheels via an eight-speed torque-converter automatic transmission. 'Normal', 'Sport' and 'Eco' modes are fitted.

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.

Here is where the G80 has all four wheels rooted more in the past than in the future.

With no electrification of any variety (hybrid, in other words), high fuel consumption is always going to be the real price paid by going for a Euro-5 spec twin-turbo V6 weighing some 2100kg.

The official combined average figure is 11 litres per 100km, for a corresponding carbon-dioxide emissions rating of 250 grams/km. On the highway that drops to 7.9L/100km and soars to 16.3L/100km in the city cycle.

With a 73L fuel tank, that combined average number means a driver can expect around 660km of range between refills of 95 RON premium petrol, though Genesis says this G80 will also run on E10 ethanol blend.

Now, our trip computer said that we averaged less than the official figure, at just 9.7L/100km, but our pump-to-pump testing ended up being 11.4L/100km. Which isn’t that bad.

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 Genesis G80 3.5T AWD SL drives in a similar way to the big brutish American-inspired Caprice and HSV Grange V8s, in that it delivers effortless, lazy performance with a sophisticated twist.

No slouch off the line even in Eco mode, the twin-turbo V6 leaps into action if you’re heavy on the throttle in Comfort mode, hunkering down as the speed piles on quickly.

With 'Launch Control', the claimed 0-100km/h sprint time is 4.9 seconds, though in regular mode it is rated at 5.1s on the way to a top speed of 250km/h.

And while the enhanced exhaust orchestrates a nice warble from behind, it remains a strong, smooth and silent performer.

The AWD system is RWD-biased and is continuously variable according to prevailing conditions, performance and grip.

The SL also features an electronic limited-slip differential for better traction and grip, as well as rear-wheel steering that either counter-steers the rear wheels in relation to the front ones for a tighter turning circle (11.8m) or parallel steers them for “enhanced steering responsiveness and stability at high speed.”

Selecting 'Sport' or 'Sport+' is met with distinctly more-urgent responses, with the transmission holding on to ratios as the revs approach the red line, which can be annoying around town.

It’s quite surprising – and probably a good thing – that the beautifully balanced and connected steering can be light and easy when you’re relaxed, and yet hefty to the point of feeling heavy when you’re really on it. Likewise, the brakes in 'Comfort' are pleasantly progressive. In 'Brake Sport' they’re fiercely responsive.

Note that, in Sport+ with the safeties off, the SL's tail can become very playful indeed, even in bone-dry conditions.

Suspension is via multi-links at both ends of the car, whilst the SL grade includes what Genesis calls “Road Preview Electronic Control Suspension (ECS)”, that scans the road ahead and then adjusts the adaptive dampers for better ride comfort.

That all said, the Genesis’ sheer size and weight keep it from feeling like an out-and-out sports sedan. The speed and AWD grip is there - tyres are Michelin Pilot Sport 4S (245/40 fr - 275/35 rr) - and the handling results in some pretty astounding agility for one so large, but the steering connection, balance and alacrity are more about confidence and competence than light-footed athleticism.

This is no cut-price BMW M5. But HSV Grange owners might recognise something in its muscular good manners.

And what of the SL’s four-wheel steering? It provides a degree of tuck-in at speed which can catch out the unaware driver, though of course, it is also a boon for round-town manoeuvrability. The tight turning circle that ensues is incredible for one so long.

Ultimately, though, it is a large and heavy sedan that never quite stops feeling that way. It won’t shrink around you despite being an easy and rewarding car to drive.

Out in the wet, the AWD contributes to the G80’s squatted-down attitude, feeling impervious to prevailing external conditions.

But it’s also not quite the sumptuous luxury liner that, say, a Mercedes S450 is.

Very civilised on smooth roads, with a decent level of absorption from the multi-link suspension, the G80 struggles a little with smaller-frequency bumps at times, but then does a great job smothering the larger ones. It is certainly within the luxury sedan expectations for refinement, isolation and ride comfort, but just not the best.

If you stick with freeways and highways, this thing will bring years of civilised pleasure and punchy performance. It is a rapid yet relaxed grand touring family cruiser.

The Genesis G80 scored a maximum five-star ANCAP assessment all the way back in December 2020, though this figure does not cover the 3.5T model as tested by us.

Along with 10 airbags (including front-centre and driver’s knee protection), it is fitted with a wide variety of advanced driver assist systems (ADAS).

These include 'Autonomous Emergency Braking' (AEB) with forward-collision avoidance (taking in car/pedestrian/cyclist as well as junction turning/crossing detection), lane-keep assist, lane-change and evasive steering assist, rear cross-traffic alert, blind-spot warning/collision avoidance, traffic-sign recognition, adaptive cruise control, parking collision avoidance, safe-exit alert, surround-view monitors, driver-attention warning, traffic-sign recognition and auto high beams.

There are also two ISOFIX child-seat fixtures and a trio of child-seat anchorage points in the back seat.

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 Genesis G80 comes with a five-year/unlimited kilometre warranty, five years of what it calls 'premium' roadside assistance (increased to 10 years if serviced at a Genesis dealer) and five years/75,000km of free servicing. Service intervals are every 12 months or 15,000km.

While these are about on-par with most brands, it is behind better mainstream warranty and aftersales services, which are seven, and in a few cases, 10 years in length.
