Lexus Gx550 vs Cadillac Vistiq

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 Vistiq is a properly luxurious car that cleverly undercuts all the premium players. It has a flashy exterior with a generously equipped and spacious interior. Plus, it’s got enough oomph to move a small mountain.

Cadillac seems to be onto a winner with this car, especially at this price point. However, it will be interesting to see whether buyers of big SUVs like this are willing to make the jump to electric. The upper large SUV segment has been dominated by the Toyota LandCruiser and Nissan Patrol for decades now and I don’t see this changing anytime soon.

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.

There’s no way around it, the Vistiq’s exterior design is over the top and flashy. You’ll either love it or hate it.

I particularly like this car’s silhouette. It has a long and boxy roofline that gives off baby Escalade vibes, though you wouldn’t necessarily call this car small given it measures over 5.2 metres long…

One of the features that can read as gimmicky is the lighting animation that plays when you unlock and lock the car. They are rather long and obnoxious, though they’re a fun novelty feature to show off to your friends and family.

Inside, the design is jaw-dropping. It’s top-notch luxury with oodles of soft touches, premium-feeling switchgear and high-end tech.

The showpiece is the 33-inch curved display that houses not only the digital instrument cluster but the touchscreen multimedia system. It’s a stunning unit.

Out tester's brown interior combo looks gorgeous on the plush seats and contrasts well with the dark metal finishes.

Speaking of the seats, they’re surprisingly finished in synthetic leather but the smell in the cabin can convince you otherwise.

One of the few interior finishes I don’t love is the glossy piano black on the steering wheel and door cards. You interact with these often and they show fingerprints easily.

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.

The front seats in the Vistiq are delicious. There’s so much adjustability, plus they’re heated, ventilated and have a fantastic massage function. It’s a great space to be in regardless of whether you’re driving or not.

Ahead of the driver the steering wheel has a lot of physical buttons and switches that are clearly labelled, though as I just mentioned, the fingerprints quickly make it look grubby.

The digital instrument cluster is bright, clear and easy to refer to at a glance, plus it has a number of layouts you can choose from. On the right-hand side there’s even a small touch section where you can cycle between the trip computer readouts, among other things.

Moving across, the central touchscreen multimedia system is big, bright and high-resolution. It’s also an easy interface to navigate through thanks to the shortcut buttons always at the bottom of the screen.

The far side of the screen can be a bit of a stretch from the driver’s seat at times, but thankfully Cadillac has included a rotary dial controller. It’s also a great way to minimise fingerprints on the screen.

There’s Google Built-in as standard, meaning there’s integrated Google Maps, the Google Assistant, plus you can download a range of different apps, like Spotify, from the Google Play Store. It’s a seamless ecosystem.

Thankfully there’s still wireless Apple CarPlay and Android Auto as standard. Connection with my iPhone 15 Pro Max was rock solid, though the resolution doesn’t appear as high as the native interface.

Underneath the central touchscreen is a secondary touchscreen for altering the climate control for all three rows, as well as the seat heating, ventilation and massage. It’s similar to the system Audi has in its flagship models and exudes a premium vibe.

Up front there are two cupholders, two wireless chargers, two USB-C ports, a large open section under the centre tunnel, a centre console box, plus a glove box that needs to be opened by using the touchscreen.

Moving to the second row, it’s an easy car to hop in and out of thanks to the easy access/exit system which drops the air suspension to its lowest setting. You’re not looking for sidesteps at all.

In Australia the Vistiq is only being offered with a six-seat configuration, meaning in the second row you get separate captain’s chairs. They’re lovely to sit in, have a dedicated armrest and are heated.

At a leggy 182cm I have an adequate amount of legroom behind my own driving position. Headroom is also great.

It’s worth noting that the second-row seats are fixed and don’t slide back or forward. They only recline which is still a nice way to get more comfortable.

Second-row amenities include a touchscreen on the back of the centre console to control the climate control, among other features, as well as air vents on the centre console and B-pillar, USB-C ports and a pull-out section with cupholders.

Going to the third row, you can either slide between the two captain’s chairs, or press a button on the side of the second-row seat which quickly pushes it out of the way. The latter allows for a clear entry/exit path.

The third-row seats are mounted low, making it feel like there’s a knee-up sensation, but there’s enough space for two adults to sit side by side. It’s a surprisingly usable space, though legroom isn’t palatial.

In terms of amenities there is a USB-C port, cupholder, air vent and padded armrest on each side.

At the back it took me a long time to figure out how to open the boot. Turns out you push the Cadillac badge… Thank you Google.

With all three rows of seating upright there’s 430L of boot space which is enough for a few shopping bags. Thankfully there’s a generous underfloor section which is big enough for charging cables among other odds and ends.

The third and second row seats fold electronically from the boot which is a lovely convenience feature. With them folded there’s over 2200L of space which is massive.

Like many EVs, there’s no spare wheel which isn’t great if you do long-distance driving away from tyre repair shops.

Continuing the gripes, there is no front boot despite the large bonnet. If you take a look it’s mostly taken up by electrical componentry.

Cadillac is only offering one fully-loaded version of the Vistiq in Australia, the Platinum, which is priced from $116,000, before on-road costs.

This is not a small amount of money, but it’s notably more affordable than its key rivals, the Hyundai Ioniq 9 and Volvo EX90. Only the Kia EV9 is cheaper but it’s not as well-equipped.

Speaking of standard equipment, the Vistiq is filled to the brim with it. Highlights include 22-inch alloy wheels, adaptive air suspension, rear-wheel steering, a 33-inch curved display, 23-speaker AKG sound system, four-zone climate control and six seats wrapped in synthetic leather.

You’re really not looking for anything more, however compared to the US-spec model it misses out on a head-up display.

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. 

The Vistiq is powered by a dual-motor all-wheel drive set-up with ridiculous total system outputs of 459kW and 880Nm.

This is enough to send it from 0-100km/h in just 4.2 seconds, which is wild given it has a kerb weight of almost 3000kg.

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.

Feeding these electric motors is a 91kWh lithium-ion battery pack which allows for a claimed range of up to 461km, according to WLTP testing.

Cadillac claims the Vistiq consumes an average of 22kWh/100km, which is on the higher end, but you need to remember this is a hulking big SUV.

In terms of charging, AC charging is available at rates up to 22kWh, whereas DC fast-charging is offered at rates up to 130kW.

The former is rather competitive, allowing up to 95km of range to be added per hour, whereas the latter is mediocre as other luxury and Korean rivals can do well over 200kW of peak fast-charging.

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. 

Behind the wheel of the Vistiq there’s an immediate elevated and premium feel. Even though EVs are already naturally quiet, Cadillac seems to have installed a lot of insulation, making it very hushed in the cabin.

As a result you pick up on other noises and disappointingly this Vistiq tester had a random rattle coming from behind the dashboard when travelling at higher speeds. It’s unclear if it’s just this car, but it doesn’t speak well to great long-term quality as the car had only done 2000km.

The Vistiq is the kind of car you feel like being driven around in. It’s so smooth, measured and calm.

Despite this, there's a ‘V’ button on the steering wheel which activates the ‘Velocity Max’ drive mode. It unleashes the full 459kW and 880Nm, making this 3000kg box on wheels absolutely haul.

It’s frightening how quickly this car can accelerate from a standstill. You’ll be leaving virtually everyone in your dust at the lights.

As I alluded to before, the Vistiq is a very comfortable car and this is largely due to the adaptive air suspension system that comes as standard. There are a range of different heights to choose from, ranging from lifted to slammed. All of which look awesome from the outside.

The suspension does a great job of rounding off pimply urban road imperfections. It’s so good you forget there are huge 22-inch alloy wheels as standard.

Unlike many American cars, the suspension isn’t overly floaty and soft, instead creating a balanced ride. Goldilocks would approve.

The only times the suspension feels out of its depth is when you hit a bigger bump at a higher speed. It can feel a little crashy from inside the cabin, but it never feels too firm.

There’s no way around it, the Vistiq is a big car and it swallows up a lane with ease. Despite this, there’s a rear-wheel steering system as standard which turns the rear wheels the opposite direction of the front at low speeds.

As a result the turning circle is much smaller than you’d expect. This means you can zoot around tight, multi-storey carparks like you’re in a much smaller car. It also makes parking a breeze.

Although you’d expect this powerful and heavy car to come apart in the bends, it holds its own rather well. It’s far from a sports car, but it limits the body roll to an extent and the tyres provide enough grip.

The Cadillac Vistiq hasn’t been assessed by ANCAP yet and is therefore unrated.

As standard there are seven airbags, autonomous emergency braking (AEB), blind-spot monitoring, rear cross-traffic alert, lane-keep assist, lane centring, adaptive cruise control, front and rear parking sensors, as well as a surround-view camera.

It’s all pretty standard on this front, however, a cool feature is the ‘Night Vision’ system which comes up on the digital instrument cluster and allows you to see potential dangers like animals, for example, better at night.

The safety systems all do a good job for the most part, however the driver attention monitor is too sensitive. When it goes off it physically vibrates the seat, which feels a little too personal for my liking.

It also vibrates for the blind-spot monitoring, rear cross-traffic alert and even the parking sensors.

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.

At this stage Cadillac hasn’t fully detailed the ownership package for the Vistiq.

There is a five-year, unlimited-kilometre warranty, as well as an eight-year, 160,000km warranty for the high-voltage battery. There's also five years of roadside assistance.

Logbook servicing is required every 12 months or 12,000km, whichever comes first, however pricing hasn't been confirmed yet.

“Service pricing for the Cadillac Optiq and Vistiq in Australia will be announced in the coming months - as we progress our planned dealer expansion, including new franchised locations in Melbourne and Brisbane," said General Motors ANZ General Manager Jess Bala.

It’s worth noting that Cadillac is still scaling its dealer network in Australia and currently only has select locations in certain capital cities.
