Lexus GX vs Lexus LS460

What's the difference?

The new Lexus GX 550 Sports Luxury looks fantastic and has enough mod cons to satisfy a family but it’s not as luxurious as you’d expect from a premium brand and the fuel economy and driving range will turn off some. But if you’re still interested, there’s a lot here that will make you happy and it’s one of the smoothest 4WDs I’ve driven.

The Lexus LS 500 and 500h are both exceptional cars. The ‘obnoxious’ styling especially to the grille makes the offerings from BMW, Benz and Audi look bland and overly corporate inside and out. It’s really in the dynamics department that the LS falls short of its rivals and only the LS 500 is enjoyable if you like to drive with a degree of conviction. 

Both the LS500 and 500h, though, have wonderfully comfortable rides and this together with those sumptuous interiors makes these the perfect place to be if you’re in the back being swiftly and quietly taken to you next meeting.

For me the sweet-spot pick would be the LS 500 F Sport for its value and dynamic ability.

The new GX 550 looks massive and while it shares the same platform as the Toyota LandCruiser 300 series, it doesn't share all of its bulk. They both stand at 1980mm wide but differ on length (5015mm vs 4980mm) and height (1670mm vs 1950mm), respectively.

The new design is fabulously rugged but each body panel looks meticulously crafted and is just the right size. This just means the proportions look right and your eye sort of glides over the big body rather than stopping on any one feature.

But having said that, there are a lot of nice features to focus on, like the long LED headlights and rear strip light, auto-folding side steps, 22-inch alloy wheels and sharply styled rectangular side mirrors.

The tailgate window can also be opened if you need to pop something into the boot but don't want, or have the space, to open the tailgate itself.

The styling takes a minor nose dive once you hit the cabin, though, because it doesn't look as sumptuous as you'd expect in a premium SUV.

I love the utilitarian and military vibe of the vertical dashboard, chunky air vents and relatively small windscreen. It looks great but some trims are plasticky and the touchpoints, while soft, are not Lexus-plush.

However, the technology looks gorgeous with an integrated 14-inch multimedia display and a 12.3-inch digital instrument cluster. The fixed sunroof with its two settings (clear or opaque) is also a lovely feature.

But on a whole, the GX 550's European rivals outclass it with their flashier cabins.

“You’re either going to love them or hate them.” You can bet that whenever you’re told this just before being introduced to somebody then that somebody is going to be downright obnoxious. The same goes for the LS, well it’s face anyway, because those are the kinds of statements made about that grille.

The thing is, the LS needs an obnoxious face because its up against The Establishment -  the Mercedes-Benz S -Class, BMW 7 Series and Audi A8, and given there’s no way they’ll ever let Lexus into their little ‘club’ it’s good that the LS has steered clear of imitating them and is boldly different.

This was also the type of thinking which inspired the grille’s creator, Tokuo Fukuichi. The so called ‘spindle grille’ first appeared in 2010 on the CT200h before rolling out to the rest of the Lexus line-up. The look polarised the opinions of fans and even executives inside Lexus. But Fukuichi was adamant the key to the brand’s survival and success was to not to be boring.

That massive gaping mouth is anything but boring, and for this new-generation LS the spindle grille has been overhauled. Yes, some car companies might make a few tweaks to a grille, but not Lexus. Using a CAD computer program, it took designers six months to refine each of the 5032 surfaces on the F-Sport’s grille and the more than 7000 on the Sports Luxury’s. If only you didn’t have to slap a number plate on these exquisitely spun net-like structures.

New LED headlights and the ‘Zorro blade-slash’ LED running lights are equally obnoxious and therefore perfectly suited for the LS’s face. So too are the enormous air inlets below them in the bumper. If only the rest of the car’s exterior was as wild and not mild and milder the further you get from the grille. The rear looks stately, modern and sleek but could have done with something more adventurous (similar to IS’s taillights).

But the LS’s insides make up for that dullness, with a cabin that’s decadent and alien at the same time. A dash which sweeps from door to door features asymmetrical string-like design elements which are a theme carved through wood and glass and stitched into leather throughout the cabin. The quality is superb, while the fit and finish is better than I’ve seen on some of its competitors.

There are four no-cost interior packages on the Sports Luxury ranging from 'Moon White' trim with walnut decorative inlays to black trim with 'Crafted Latte' inserts. But it’s the $9800 optional 'Black with hand-pleating' and 'Kiriko' glass which is a stand out. It’s an intriguing look, the pleated fabric which cascades around the hand-cut Japanese glass.

The F Sport’s cabin is less decorative with seats that hold you tighter in three no-cost option leathers from 'Moon White' to 'Flare Red' with aluminium door and dash decorative elements.

Both cabins are sumptuous, although they fall a little short in gob-smacking tech like those amazing, expansive, floating dash screens and the virtual instrument cluster in the S-Class. Yes, there’s the large screen up front and the seat-back screens in the rear but the styling of the graphics and typeface reveal the Toyota DNA.

The LS has the presence a prestige brand’s flagship car should - imposing, long and wide. Look at the LS’s dimensions. At 5235mm end-to-end and 1900mm across, the LS is longer and wider than a Mercedes-Benz S-Class, but swoops in lower at 1450mm. The LS’s wheelbase is longer than a regular S-Class’s at 3125mm, too.

Apart from the grille you can tell an F Sport from a Sports Luxury by its black brake calipers and black elements in the front bumper, boot lid and sill.

To tell a 500 from a 500h, the difference is subtle. There are the badges, of course, but the 500's rear bumper also has a different design with chrome exhaust surrounds.

The cabin of the new GX 550 is fairly practical with plenty of head- and legroom in each row (yep, even the third!). When you first hop in, it can feel a big snug on elbow-room but this feeling quickly dissipates.

Despite a 215mm ground clearance, access is pretty good for the front and middle rows due to the wide door apertures and side-steps. Third row access is a bit awkward for an adult but my eight-year old loved scampering back there this week.

The electric front seats are comfortable with their extra functions and I like the way the massage feature extends to the seat cushion as it limits fatigue on longer journeys. However, you sit on top of them rather sink into them which makes it feel a little trucky at times.

The wide middle row has a bench seat that will be comfortable for kids but an adult might get a sore behind on a long trip. The transmission tunnel also compromises foot room for adults but the seat is wide enough to make use of all three top-tether anchor points (there are ISOFIX mounts too).

It was a little bit of an effort to lift my big booster seat into the back because the GX 550 sits so tall but otherwise, there's plenty of room around a child seat for them not to feel like a sardine.

Individual storage is made up of a glove box that fits an owner's manual, a small shelf in the dashboard and a middle console that doubles as a cool box (mini fridge) and can fit up to four cans or bottles in it.

Each row gets four drinkholders and two USB-C ports but the front also enjoys a 12-volt socket and wireless charging pad. There's a 220V domestic plug port in the boot for larger appliances, too.

It's sometimes awkward to use the wireless charging pad because it's easy for your phone to slide around on it and it quite often disengaged from charging.

My son enjoyed all of the other amenities in the middle row, like the reading lights, climate control, two USB-C ports and retractable sunblinds and I applaud carmakers when they position rear directional air vents in the pillars and/or roof. It just makes it so much easier to cool down sweaty kids!

The 14-inch multimedia display has clear graphics and a responsive touchscreen. The layout is easy enough to get used to after spending some time with it and the sat nav is simple to use.

I like that the sat nav directions can be pulled into the 12.3-inch digital instrument cluster and head-up display.

There is a Lexus connected services app, which you get a three-year subscription to. It's easy to connect to the wireless Apple CarPlay and there is also wireless Android Auto.

The system also has Bluetooth and digital radio, which is a delight to use through the 21-speaker Mark Levinson sound system.

The cabin is rounded out by the well-shaped boot which has a massive 1063L of capacity when the third-row is folded. That's been more than enough for my family's needs this week and my German Shepherd was pretty comfy back there, too. The powered tailgate has a kick-function and there is a full-size spare wheel underneath the car.

Anything with a 3.1m wheelbase has to be practical right? Well, legroom in the back is excellent, but I can’t properly stretch out in that reclining rear seat with the ottoman without my feet hitting the seatback.

Headroom is also a bit a restricted in that rear row for me, too. That’s something to keep in mind for taller passengers (I'm 191cm tall).

A cargo capacity of 480 litres is 30 litres shy of the Mercedes-Benz S-Class, while the cooler box in the rear (that comes with the Sports Luxury trim) eats into the boot space and drops the total to 440 litres.

The LS is a five-seat sedan, but that centre rear seatback folds forward to become the armrest and houses the controls to the massage and reclining functions, plus two cupholders.

There’s another two cupholders up front and pockets in all the doors. While the storage area under the centre console armrest in the front and back is good – that’s about it for storage.

An access mode will raise the car by 30mm when getting in and lower it by 10mm when getting out. Those wide opening doors also make entry and exit easier.

The line-up is simple. There are two powertrains: the turbo-petrol V6 LS 500, and the petrol-electric LS500h hybrid, and there's no price difference between them. Then, there are two trim levels: the F Sport for $190,500 and Sports Luxury for $195,500. 

Coming standard on the F Sport are 'F Sport' seats with leather upholstery, heated front and rear seats, dual-zone climate control, 28-way power adjustable front seats and head-up display. The multimedia system comes with a 12.3-inch screen, sat nav, DVD player, DAB+ digital radio, Bluetooth connectivity and a 23-speaker Mark Levinson sound system.

There’s also LED headlights, 20-inch alloy wheels and a kick-open tailgate. While the F-Sport misses out on some of the plush features of the Sports Luxury it does get hardware for better on-road dynamics which you can read about in the driving section below.

The Sports Luxury has that large screen, those power adjustable front seats and the multimedia system with that Mark Levinson stereo, too, but adds much more. The front passenger seat slides and folds itself forward to allow the seat behind it to recline and extend its ottoman-style leg rest. 

Both rear seats are 22-way power adjustable and heated. If you’re lucky enough to be lounging back there, you’ll also two 11.6-inch seat-back screens with a DVD player. Plus, there’s four-zone climate control, a rear cooler box and power sun shades.

The F-Sport and Sports Luxury have their own choice of no-cost interior options. The Sports Luxury also gives you the option to buy (for $9800) one of four special interior packs – you can read about the standout one with the hand-cut glass below.

There are 11 body colours to choose from: Sonic Quartz, Sonic Silver, Titanium, Liquid Metal, Onyx, Graphite Black, Vermillion, Scarlet Crimson (a dark red), Metallic Silk, Deep Metallic Bronze and Deep Blue.

All GX 550 grades share the same 3.5L V6 twin turbo-petrol engine which produces up to 260kW of power and 650Nm of torque.

This 4WD has high- and low-gearing, as well as a bunch of driving modes to suit most occasions, like 'Eco', 'Comfort', 'Sport' and 'Sport+'.

The 10-speed automatic transmission shifts through its gears smoothly and it always feels like it's engaged in the right gear. Which isn't always the case for a big SUV!

The Sports Luxury is fitted with a towing hitch and cover but unlike the base Sports grade which has a 3.5-tonne braked towing capacity, this model only has a 3130kg capacity which might not appeal to families with big toys to tow. 

Let's talk engine specifications .The LS 500 has a 3.5-litre twin-turbo petrol V6 making 310kW/600Nm, with drive being sent to the rear wheels via a 10-speed automatic transmission. That's impressive horsepower, but this car is heavy is a weight of about 2.3 tonnes.

The LS 500h has a 220kW/350Nm 3.5-litre V6 (a different engine to the 500’s) plus two electric motors driving the rear wheels. The total power output is 264kW. Shifting gears in the 500h is a continuously variable transmission (CVT). Just a reminder, too, the LS 500h is not  a plug-in hybrid. Regenerative braking re-charges the lithium-ion batteries.  

If you're looking for a diesel, you won't find one here. Same goes for a manual gearbox. And, while buyers can choose an all-wheel drive (awd) Lexus LS in other markets around the world, ours are all front-wheel drive.  

I didn’t have high hopes for fuel economy because the official combined (urban/extra-urban cycle figure is a hefty 12.3L/100km but after mostly open-road driving, with some urban stuff mixed in, my real-world average came in at 11.8L.100km! This figure is based on my actual km travelled (358km) and litres of fuel used (42.41L).

While I’m surprised by the fuel usage result, I wouldn’t say this car has good fuel economy compared to its diesel-powered counterparts but it’s not terrible!

The GX 550 has a relatively small fuel tank compared to its Toyota cousins at 80L and based on the combined fuel cycle, you’ll get a theoretical driving range of up to 650km.

Not all that great. Not for a big family mover and not if you’re typically driving in the city, where fuel usage will be a lot higher.

The GX 550 only accepts premium unleaded petrol (95 RON), too.

The LS 500 has an official fuel consumption of 9.5L/100km while the 500h’s is 6.6L/100km after open and urban road driving. We drove both cars on mainly country roads and saw an average of 10.1L/100km in the LS 500 and 9.1L/100km in the 500h.

Oh my goodness the Sports Luxury is a masterclass on 4WD refinement! You never feel the bulk or weight of this massive SUV when you’re driving it. The power delivery is effortless and there’s lots of grunt available when you hit hills.

The handling is also very good with responsive steering and enough road feedback as a driver to make you feel comfortable with what the car is doing. There is some roll in corners but it can tackle more corners at speed than I thought it would. 

The high driving position makes me feel like I can see a long way ahead yet while visibility is mostly good, it can be compromised when you have the side window shades and the third row headrests up. Which is why I love the digital rear view mirror.

Overall, ride comfort is good with forgiving suspension and low cabin noise, even at higher speeds. It’s pretty easy to chat with all rows and there’s not a lot of engine noise which adds to the refinement. I do like hearing a V6 rumble but that’s just a personal preference. 

I was a little worried about hitting my local Westfield car park but this is a nimble SUV to manoeuvre and parking it is a breeze with the 360-degree camera system and parking sensors. 

My first experience of the new LS was from the back seat of a 500 Sports Luxury being driven from the airport to the venue where Lexus Australia would deliver the presentation on its fifth generation of the car.

Seat reclined, I was whisked quietly and comfortably through the traffic, barely any road or wind noise, the ride was superb on that air suspension, a little floaty but still damped well enough for it not to become bouncy, with minimal head sway (the movement that makes you car sick).

Cocooned in leather with seat-back screens for audio and DVD the ride and environment was just right for a limousine chauffeuring important business types who need swift and tranquil transportation. Not for weirdos like me who were only interested in the way the front and back multi-link suspension kept a 2.3-tonne car with a 3.1m wheelbase so civilised, even through roundabouts. I wondered if this was actually the best way to experience the LS – from the back seats, being driven?

When I did drive the 500 and 500h in the two trims later it more or less confirmed that first impression. The 500 in F Sport trim was the best to drive, while the 500 in Sports Luxury was the best to be driven in. Why? I’ll explain.

The LS 500’s 3.5-litre twin-turbo V6 makes more power than the hybrid for starters, which is always a good thing when you need to move a car this heavy. Even then the LS 500’s acceleration isn’t super quick, and the engine needs to work hard when asked to get a wriggle on. That 10-speed automatic transmission is excellent though. 

The same can’t be said for the CVT in the 500h which under harder acceleration does what CVTs do in that situation, make more noise without seeming to get the drive effectively to the wheels.

The 500h’s naturally aspirated V6 is a good thing, but it seems the weight of the car and the CVT work against it being exciting to drive. After a couple of hundred kilometres in a 500h blasting through the countryside steering it became tiresome rather than rewarding with the engine constantly kicking in and whining incessantly when asked for more beans, please. 

This car is far better suited to slipping silently through city streets than it is galloping through the bush – that’s where the 500 is a lot more at home.

The 500 and 500h are rear-wheel drive cars, and this, along with an almost 50-50 balance, sets the ground work for good cars to pilot. The F-Sport trim adds an active rear stabiliser bar as standard equipment and brings a more sophisticated version of Lexus’s 'Vehicle Dynamic Integrated Management' (VDIM) – a stability system using data from suspension, ABS, traction control, electric power steering, the stabiliser bar and rear steering. The result is the control of longitudinal, vertical, yaw, roll and pitch movements for better ride and handling.

The F Sport trims adds bigger brakes, too with 400mm x 36mm discs on the front and 359mm x 30mm at the back, plus staggered tyres with 245mm rubber at the front and 275mm at the rear.

The electric steering is light, which makes it easy to manoeuvre in carparks, and an 11.2m turning circle is great for the class. 

On the open road at speed the steering is pinky-finger light even in Sport+ mode, and while it’s smooth and accurate, I want to feel more connected to the wheels and where they’re pointed.

While the LS 500 is more the driver’s car than the 500h neither perform as well dynamically as Benz’s S-Class, but from the back seat the LS feels just as comfortable and even plusher.

The Lexus LS has not been crash tested, but all the signs are there that this is an exceptionally safe vehicle, from the structure of the car to the advanced safety technology such as AEB (forward and reverse) with pedestrian detection, lane keeping assistance and adaptive cruise control.

For child seats there are three top tether anchor points and two ISOFIX mounts across the rear seats.

Both the 500 and 500h are fitted with run-flat tyres.  

Lexus offers the GX 550 with a five-year/unlimited km warranty, which is fairly standard compared to its Euro rivals.

You get five years capped-priced servicing which costs $5950 but the servicing schedule is a bit of a bear at every six months or 10,000km, whichever occurs first.

The Lexus LS is covered by a four-year/100,0000km warranty. Servicing is recommended every 15,000km or 12 months. There is no capped price servicing program. Being a Toyota family product the Lexus LS also comes backed by the same reputation for reliability and you may experience lower maintenance costs than perhaps its German rivals.
