Cadillac Vistiq vs Lexus Rx450H+

What's the difference?

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 Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

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 RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

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.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

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.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

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.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

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 RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

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.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
