Genesis G80 vs Lexus GS350

What's the difference?

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.

Weirdly, given all the good things I've had to say about the GS F Sport, it doesn't quite hang together. It's missing that certain something the Europeans have in their chassis, particularly the BMW 5 Series, and with ageing interior tech, it's struggling to keep up.

It's a car built for specific tastes, and they're more California than Straya. And that's perfectly okay, but unfortunately, that doesn't translate to a stampede of buyers. Having said that, none of its German rivals (or its beleaguered Japanese counterpart, Infiniti) could claim wild sales success either.

The GS is a terrific car, underrated but also just not quite there for my taste. The GS F, though, that's another thing altogether.

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.

The GS is ageing well, but it's still a bit heavy-handed around the headlights and a little on the slabby side along the flanks. It doesn't look poised for action, even with the F Sport additions, but nor does it look frumpy, mostly due to the whopping blacked-out spindle grille, a Lexus signature. 

The rear end is good looking but a bit bluff, again neither surprising or delighting.

Little has changed inside, but it's still a very nice cabin, and always will be apart from a couple of clangers (the gear shifter looks super-cheap). 

What's more, it's welcoming, lots of very nice materials, comfortable, seats - it's exactly what it needs to be. Whatever you might think of the looks, one thing is absolutely certain - if anyone builds cars better than Lexus, it's a very, very short list.

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.

Being a big car, there's plenty of room inside. Four passengers will be very comfortable although rear legroom was a bit on the skinny side given the car's size.

The cabin contains a good-sized console bin, four cupholders and each door pocket into which you could conceivably slot a bottle.

The 520-litre boot is a useful shape, with a sensible load height and a space-saver spare under the floor. The 5 Series and E Class both best the Lexus by 10 litres, so the GS isn't far off the norm.

We had the pleasure of the GS 350 F Sport for the week, which is well over $10,000 cheaper than the Luxury and is therefore the 'default. If you're not sure what F Sport means, it's Lexus' answer to an M Sport or AMG pack, without all the high-powered engine shenanigans to go with it. If that's what you're after, the V8-powered Lexus GS F is definitely for you.

Starting at $95,300, the F Sport has a spectacular standard features list - 17-speaker stereo, 19-inch alloys, variable-geared four-wheel steer (!), adaptive suspension, dual-zone climate control (with moisturising function), hectares of leather trim, head-up display, electrically-operated heated and ventilated front seats, rear sunshade, F Sport instrument screen, auto LED headlights, keyless entry and start, sat nav, front and rear parking sensors with around-view cameras and a space-saver spare.

The media system is run from Lexus' 12.3-inch screen embedded in the dashboard and controlled from an infuriating console-mounted mouse-clicker with a couple of shortcut buttons. It really is spectacularly irritating and made worse by the rotary dial stationed next to it that acts as the drive mode selector. Why not use that instead? 

As ever, the system is mildly baffling to use and hard to look at, but the sound is absolutely lovely from the Mark Levinson-branded speakers. Lexus is persisting with a DVD player but it also has DAB+.

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.

Lexus fits a 3.5-litre (2GR-FKS) naturally-aspirated V6, delivering 232kW/380Nm to help shift the 1745kg GS. Power goes to the rear wheels via an eight-speed automatic. Lexus claims the sprint from 0-100km/h is completed in just six seconds.

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.

A real world 13.7L/100km is a solid miss of the claimed 9.3L/100km, which itself is hardly earth-shattering. It's a big heavy car and that's the penalty. It drinks fuel fast, so the 66-litre fuel tank does drain quickly and it's worth knowing you have to fill it with the 95 RON or better.

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.

There are things you expect in a Lexus. Quietness. Composure. Smoothness. The GS delivers all three of those things effortlessly. But it has a few extra things in its bag that I can't say I was expecting.

For a start, the 3.5-litre V6 moves the car without any carry-on and in doing so, I was constantly amazed at how quickly the speed in the head-up display reached the posted limit. It just doesn't feel or sound like a six second car, but there you are. The transmission is virtually faultless, the engine sound distant and refined, the power impressive.

It's a heavy car, no question, but two things work to make it feel much lighter. First - and it doesn't matter which mode you choose - the adaptive suspension somehow knocks about 200kg out of how heavy the car feels. The brakes, while a little soft on pedal feel when you first step on them, are very effective and again help to make the car feel lighter than it is.

The four driving modes are quite distinct. As usual, Eco makes everything soft and doughy or as I prefer to say, unpleasant. Normal is great for every day, with just the right throttle response and steering weight.

Moving to sport ups the aggro slightly while Sport+, while never harsh, firms everything up to the point where it starts to feel like a different car. Sport+ makes the car feel race-car pointy, the suspension holds the body in check and the power seems readily available without jerky progression

The all-wheel steer is a big part of the change in feel. It's is especially sharp in Sport+ mode. The steering's gearing changes up quite a bit, meaning a lot less steering lock required for your favourite hairpin bend. Of course, at real speed it all calms down because neither you nor Lexus are fond of sneezy lane-changes or Armco-swiping. At first I thought it just made the big car feel a bit too nervous but as I got used to it (and was able to dial it down by switching back into a less racy mode) I found it fun but a little bit out of character with the car itself.

And just because it's the F Sport, that doesn't mean it can't do all the things you'd expect from a Lexus. You can still waft, you can still creep up on people and it's really very comfortable when you're cruising or stuck in traffic. 

The GS scores 10 airbags, ABS, stability and traction controls, blind spot monitoring, rear cross traffic alert, forward AEB, active cruise, auto high beams and lane departure warning with lane keep assist.

The GS doesn't have an ANCAP or Euro NCAP rating while the USA's IIHS (Insurance Institute for Highway Safety) rating is good for each key crash-worthiness measure. The IIHS suite of tests is quite rigorous but differ from our ANCAP/Euro NCAP standards.

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.

There's one area where Lexus smashes the Germans and that's after-sales. While the warranty is hardly ground-breaking at four years/100,000km and service intervals are reasonable at 12 months/15,000km, it's how it all comes together.

For the duration of the warranty, when the car needs a service, Lexus will either come and get it then return it to you, or give you a loan car. Anecdotal evidence suggests this continues long after the warranty runs out. Like, 10 years after the warranty runs out. 

This is a small thing, but if there's one thing I hate about car ownership, it's the servicing experience. If I was a betting man, I'd dare you to find someone who genuinely has a problem with Lexus after-sales care.

On top of that, you get a generous roadside assist package for four years.
