Lexus RZ450E vs Lexus RX350H

What's the difference?

There are sportier EVs out there, there are more tech-savvy EVs out there, but few adhere to the luxury promise quite like the Lexus RZ, particularly at its price point.

It’s this primary characteristic which sets the RZ apart from the pack for me, and while it might not be for every first-time EV adopter, it nails the brief for the existing Lexus buyer while providing a ‘luxurious’ alternative to many of its firmer, sportier and less approachable rivals.

It’s hard to look past the value equation of the RX350h Luxury 2WD when comparing it to almost all its competitors. The pricing is on point, but there are some features missing.

However, there are very few (if any) rivals with a true hybrid powertrain (sorry, mild hybrids do not count), so the RX will capture buyers looking for environmental credentials and efficiency without going full EV.

The drive experience is much better than before and it’s all wrapped up in a very stylish package. The Lexus RX should not be ignored.

I don’t think the RZ will be for everyone, but it has some very cool details and interesting angles, regardless.

It maintains the signature Lexus face, but this time has sunk the ‘spindle’ pattern deep into its plastic grille, making for a clean nose, but perhaps one which is a little too blank for some. No doubt it needs this smooth look to maintain as low a drag coefficient as possible.

Closer inspection reveals clever detailing, like the way the spindle pattern fades into the corners, and the whole look is lifted by how wide the car is. 

Sports Luxury versions are lifted further with contrast panels accentuating the width and shape.

My favourite angle of the RZ is the rear three-quarter. The coupe window line, split spoiler design, and cool strip tail-light, complete with three-dimensional Lexus branding, looks as contemporary as it gets, not to mention sportier and more intriguing than even some of its rivals.

Savvy EV buyers might know the RZ shares its platform and overall shape with the upcoming Toyota bZ4X and its Subaru Solterra spin-off, and while those two cars look near-identical from the outside, Lexus has clearly had a lot more creative licence with the design of its take on the formula.

Inside is perhaps where this car feels the most Lexus, however. The interior design is almost entirely unrecognisable when compared to the bZ4X, with Lexus going to town with its curvy, intricate design language, and plush detailing throughout.

Padded synthetic leather trims, which match the seats, adorn the doors, which are swapped out for ultrasuede in the case of the higher-grade Sports Luxury.

And Lexus has opted for a deep-set digital dash and massive touchscreen in place of the small column-mounted screen and tablet multimedia of its Toyota and Subaru relations. 

Everywhere you look, though, there’s attention to detail, with interesting material choices from the wacky carpet to the detailing on the centre console and in the door cards. It’s unmistakably Lexus, and feels premium.

Across its five generations, the RX has held significant visual appeal - especially the still-handsome second-gen version that was the first RX sold Down Under. The first-gen model skipped Australia.

The new model that launched in 2023 is a clear evolution of the car that came before, but it’s been softened and sharpened in the right areas, giving it one of the most appealing designs in its segment.

The proportions and design elements like the squat stance, unique C-pillar treatment, slimline headlights and nicely sloping roofline give it a sporty look.

In fact, I reckon it might be the best looking Lexus available today - not including the jaw-droppingly beautiful LC coupe and convertible, of course.

The interior is modern and feels like an evolution of Lexus’ previous cabin design - but elevated. The gloss black section of the dash helps here.

Levels built into the dash break up the bulk, but the interior is very grey. It could do with a dash of colour.

The synthetic leather seat trim doesn’t look premium. If you want a more expensive feeling RX, you need to pay more for a higher grade.

The RZ benefits from its electric-from-the-ground-up 'e-TNGA' platform, which offers an almost flat floor, wide, spacious cabin (despite its coupe-look rear) and there are plenty of clever touches throughout to enhance practicality.

The doors each offer a pocket with integrated bottle holder up front, there’s a wide centre console with a set of large bottle holders, and the clever dual-hinged armrest console which appears in other Lexus products, and a large bay under the multimedia unit which houses additional storage alongside the wireless charger.

Interestingly, the RZ doesn’t have a glove box on the passenger side, as this area is reserved for the infra-red projector in the Sports Luxury grade. 

Instead, the car has a cutaway underneath the bridge-design centre console for additional storage. It’s a welcome and surprisingly large area which also houses a 12V power outlet. However it’s a little tricky to reach when seated up front.

Adjustability feels good for the driver with decent leg and headroom, alongside a tilt and telescopic steering column.

There are dials for the climate controls and a centre dial for the volume adjustment, although there are still many functions - from drive mode to essential safety toggles - that are buried more than one menu deep in the touchscreen, and therefore a little clumsy to jab at while you’re driving.

The back seat offers excellent space for someone my size. At 182cm tall I had leagues of knee room and decent headroom, and of course all the soft trims continue. 

Bottle holders appear in the doors and drop-down centre armrest, and rear passengers score dual adjustable air vents and two USB-C power outlets. 

There are map pockets on the back of the front seats, and the higher-end Sports Luxury grade offers dual heated seats and a separate fixed sunroof panel for the enjoyment of rear passengers.

One interesting piece, however, is the high floor. Designed to facilitate the batteries, the high floor means you feel tilted back in the rear seats, like your knees are far off the ground.

The boot, meanwhile, is also surprisingly spacious given the raked rear window. At 522 litres it outranks most mid-size SUVs, and while it seems deeper than it is tall, it should be more than sufficient for the airport run or trips to the local Golf course.

An underfloor storage area is convenient for the stowage of your charging cables.

The RX is a five-seat only proposition in this generation - the previous model had a seven-seat option - so if you need a third row you can look at the Lexus LM people mover or massive LX 4x4 SUV, or at any number of other three-row lux SUVs like the Volvo XC90 or new Mazda CX-90.

That doesn’t mean the cabin isn’t practical. 

Up front the seats offer excellent comfort levels and ample upper body support, but not a lot of hip support.

Lexus has changed up the door handles for the new RX and it can be complicated - initially.

The interior handles bamboozled every new person that got in my press car over the three week loan. But once you realise it’s a simple push of the thumb on the handle’s thumbpad and a gentle push, it all makes sense.

Lexus calls the electrically activated door handles an ‘e-latch’. Is it tech for tech’s sake? Probably. 

I recently reviewed the Lexus LM and commented on how much I like Lexus steering wheels and that’s true of the RX, too.

It has clearly identifiable controls and feels nice in your hands. Thankfully, the cruise control buttons are housed on the wheel too, so no annoying stalk on the wheel.

There’s plenty of space across the front row so you should avoid the awkward driver-passenger elbow bump on the centre armrest.

Under the armrest is a huge central bin that opens on the driver and passenger side. There’s also a big covered storage nook forward of the shifter and another ledge above that, as well as a sizeable glove box. 

The doors have ample storage room for bottles, but the space is almost too wide. My bottle slid around when driving so I had to lay it down.

The centre console houses two big cupholders with adjustable depth in one of them. Clever touches like this and the central bin add to the appeal.

As with the Lexus LM, I am a fan of the new Lexus multimedia set-up. It has an easy-to-navigate menu along the side, easy wireless Apple CarPlay connection, and visually appealing graphics.

It’s a world away from Lexus’ previous system. That frustrating touchpad is, thankfully, in the bin.

I quite like the gear shifter with its unusual gate and even the indicator feels and sounds premium.

Small rear windows make for a rear three quarter blind spot, but visibility is otherwise good.

On a side note, the RX has very strong air conditioning - perfect for an Australian summer.

Jumping into the second row, there’s plenty of space all around and no shortage of head, leg, knee and shoulder room. Although foot room under the front seats is tight.

As with the front seats, the rear row offers comfortable seating. Kids should be happy back there.

There’s only a small transmission tunnel so middle-seat legroom is good. And in great news for passengers, the rear backrests recline. 

Lowering the 40/20/40 split-fold rear seats for more cargo space is done via a lever on the side of the outboard seats, or by a button in the boot area. There are ISOFIX clips on the two outboard seats.

Other amenities in the second row include map pockets, two USB-C ports, knee-level air vents, climate control, and a pull-down armrest with pop-open cupholders.

Open the power tailgate and you’ll find cargo space of 612 litres with all seats in place, or 1678L with the second row stowed.

That’s a decent amount of space but not class leading. The Mercedes-Benz GLE has 630L and the VW Touareg can swallow 810L.

There’s no under-floor storage because that’s where some hybrid hardware is housed. You will find audio speakers, nice carpet, a cargo blind, two 4.0kg hooks and three top tethers. No spare, only a tyre repair kit.

The range-opening RX350h Luxury 2WD petrol-electric hybrid starts at $86,904, before on-road costs, and for that amount, the standard specification list is healthy. But it doesn’t include everything.

As well as a long list of standard safety gear (see section below), the RX350h comes with three-zone climate control, heated and eight-way adjustable power front seats, electric steering wheel adjust, rain-sensing wipers, a 14-inch multimedia set-up with wired Android Auto and wireless Apple CarPlay, digital radio, sat nav, a 12-speaker audio system, five USB-C (and one USB-A) ports and more.

It is missing a few items, however, that should be standard, such as a head-up display and wireless device charging. Those features are available as part of an options pack - or 'Enhancement Pack' in Lexus speak.

For $5000 more you get those two things and a panoramic sunroof, ventilated seats, a more digital instrument cluster and other goodies. 

You can opt for an all-wheel drive version of the 350h and that adds just over $3500 to the price. If you want the same powertrain but more gear then you’ll need to step up to the $110,575 Sports Luxury.

There’s also the petrol-only RX350 in F Sport and Sports Luxury guise, as well as the flagship RX500h F Sport Performance hybrid that tops out at $124,675.

Looking at the opening price of some of its rivals, Lexus has most of them beat.

The Mercedes-Benz GLE300d starts from $144,900, the BMW X5 xDrive30d is $134,900, Porsche Cayenne starts at $138,700 and the Volvo XC90 B5 Ultimate Bright kicks off from $100,990.

Only the Volkswagen Touareg 170TDI ($89,240) and Jaguar F-Pace P250 R-Dynamic ($83,700) are close on price.

The RZ is only available with one powertrain choice, a dual-motor all-wheel drive set-up dubbed the 450e.

Unlike some systems, this dual-motor arrangement is far from symmetrical, with by far the majority of power sent to the front wheels.

Total system output is rated at 230kW/435Nm, consisting of 150kW/266Nm from the front, and just 80kW/169Nm from the rear.

Interestingly, this is significantly more punch than the Toyota bZ4X, further setting this Lexus apart.

The RZ uses a clever torque-vectoring system to make the most of this set-up when cornering, and debuts some interesting new tech like computer-balanced brakes to keep the car level under heavy deceleration as well as new adaptive pistons in the suspension to help the car adjust to different surfaces.

Powering the RX350h is a series parallel hybrid system consisting of a naturally aspirated 2.5-litre four-cylinder petrol engine, a front-mounted motor and a nickel-metal hydride battery. 

Lexus doesn’t provide combined torque outputs for the hybrid, but total power for the system is pegged at 184kW.

This drives the front wheels only via a continuously variable transmission (CVT).

Quoted range for the RZ is 470km, however this is to the more lenient NEDC testing cycle, as accepted by the Australian Design Rules. 

However, its real-world range is more like 400km, which is as it is more accurately measured to the WLTP standard.

The 71.4kWh battery pack is supported by a 150kW max DC charging speed, allowing a 10-80 per cent top-up in 30 minutes.

On a slower public AC charger, the RZ can pull a maximum speed of 11kW for charging in around six and a half hours, while single-phase charging, as you might get from a home wallbox system, at a rate of 7.0kW allows a charge time in around 10 hours.

Lexus throws in a public Type 2 charging cable, home wallbox installation, and a three-year Chargefox subscription (covering free fast charging) as part of an RZ purchase. Clever.

Officially the RZ consumes 18.7kWh/100km on the combined cycle according to the WLTP standard and I was surprised to find our car consumed 18.6kWh/100km during the test drive loop. 

For context, anything under 20kWh/100km is reasonably impressive in the premium EV space.

The official combined cycle fuel consumption figure for the RX350h 2WD is 5.0 litres per 100 kilometres, with CO2 emissions of 114g/km. You won’t get figures like that in a petrol or diesel competitor.

Over three weeks of mixed city, country, urban and freeway driving, I recorded 6.8L/100km which is not too bad given some of my spirited driving. The trip computer said 7.0L which is close to my figure.

The RX350h takes premium unleaded petrol and has a 65-litre fuel tank, so expect a range of around 950km based on our real-world consumption number.

Usually EVs, even premium ones, have a particular formula to the way they drive. 

Hefty, firm, and usually break-neck fast is the default position, with seemingly every manufacturer trying to remind buyers they too can be as fast as a Tesla.

However, the RZ breaks with the premium pack, offering a car which leans more into the luxury promise than maybe any other right now.

It’s a relatively serene space in the cabin, with notably limited wind or tyre noise, and a gentle steering tune which makes the car effortless to pivot into corners. 

This combines with the clever torque vectoring system, and lenient suspension to have the RZ simply wafting through corners.

The ride is interesting in that it is so far from the norm for the EV space. It is the opposite of firm and aggressive, with the car gently leaning into bends and barely feeling the texture of the road.

Small, rough bumps and high-frequency corrugations are dispatched with ease, the car simply floating over them, even when loaded up in corners, although, on the flip-side, longer undulations have it bouncing up and down a bit after-the-fact, perhaps a consequence of the doughy ride having to deal with the well-hidden weight of its batteries.

Despite efforts to deal with body-roll, there’s a notable amount, a consequence of the forgiving ride.

While these characteristics make the RZ a far more luxurious proposition on the road than many of its rivals, it is notable in how much it lacks a feel for the road. 

The steering is so electrically augmented it feels almost simulated, no matter which drive mode you select, and little of the road surface is communicated well to the driver. 

Even the brake pedal feels lifeless and distant, as it combines regenerative braking with the actual discs in a purely digitised progression.

The steering, acceleration and regenerative braking are all heavily altered by drive mode, with the car lacking a single-pedal drive setting, instead being fairly hands-off with the system. 

Some, looking for a particular EV drive experience, may be happy with this, others will appreciate how ‘normal’ the RZ feels in this department.

While the car feels disconnected in a sense, there’s no doubt the brakes work, the steering is effective, and it is deceptively quick. 

Its soft character might have you assuming it's slow, but a hot-hatch baiting 5.3 second 0-100km/h sprint time seems alarmingly achievable in the Sport mode.

One thing is for sure - everything described here is deliberate. Lexus has made a choice to go against the grain and do something different when it comes to the way this mid-size EV feels. 

To many existing Lexus loyalists, there will be a lot which is familiar, while providing a slice of the future, yet it might be far from the most engaging EV to drive. It certainly provides a gentler and more luxurious - if a little lifeless - alternative to the sporty status quo.

The old RX was competent and even nice to drive but not a patch on the likes of the BMW X5. The new-gen RX improves on that in a big way.

It offers solid acceleration from a standing start. Lexus says 8.1sec from 0-100km/h - without giving you chills. The sportiest RX is the 500h Performance hybrid and that covers the same distance in 6.2sec.

The transition from electric power to petrol propulsion is more evident in this model than it was in the LM350h people mover I tested recently - the RX is a little noisier. The CVT doesn’t help this, offering up an uninspiring engine note.

It is, however, a much more fun car to push into tight bends than the previous RX. It remains reasonably flat in corners, and pulls out of tem with ease, but can’t compare to the dynamics of the dearly departed IS sedan.

The 19-inch tyres have large sidewalls and as a result soak up harsh bumps on the road. The non-adaptive suspension is tuned for better dynamism, meaning the ride quality is on the firm side.

The front-wheel drive RX lost traction for a second on a sweeping uphill section of my drive route, but the electronic traction systems otherwise kept the big SUV in check. 

But around town in urban areas, there is very little to complain about behind the wheel of the RX350h.

The RX comes packed with standard safety gear and the SUV was awarded a maximum five-star crash safety rating from ANCAP in 2022.

Just some of the inclusions are auto emergency braking with pedestrian (day/night), cyclist (day/night) and motorcyclist (day) detection, intersection assist, emergency steering assist, driver monitoring, lane keeping aid and lane departure warning, adaptive cruise control, front and rear parking sensors, blind spot monitor (including stationary) with rear cross-traffic alert and safe exit assist to avoid 'dooring' incidents. 

I must say, Lexus’ (and parent company Toyota’s) driver assistance tech has come a long way.

In the early days of the pandemic during a rare non-lockdown period in Melbourne, I drove from Melbourne to Sydney in the previous-generation Lexus RX200 Sports Luxury.

The lane keeping system and adaptive cruise control were shockingly underdone. The cruise control would simply stop working when you encountered even a slight downhill section. 

Not anymore. The new, smoother lane keeping set-up uses subtle wheel adjustments, unlike the ping pong effect of the previous RX, and the cruise system is now very much in control of the speed.

The Lexus safety suite now operates without too much intervention and is hard to beat among its key rivals.

One of the key Lexus selling points is its ‘Encore’ ownership promise, which is at its best on its EV models.

For the RZ this includes a complementary 7.0kW home wallbox charger installation for those with garages, the inclusion of a wall socket and public Type 2 charging cables, a three-year Chargefox subscription keeping even your high-speed charging free for the duration.

The warranty is five years, unlimited kilometres, with roadside assist included.

Capped price servicing is available over five years, weighing in at $395 per 12 month or 15,000km interval, whichever comes first.

Lexus will also organise to pick up and drop off a loan vehicle at service time, while the high-voltage battery is covered by up to 10 years of warranty if the logbook is adhered to at an authorised Lexus workshop.

The brand also offers extra benefits through its ownership program, like deals at hotels and restaurants, as well as invites to events like track or golf days.

This is an impressive above-and-beyond suite of offerings befitting a premium brand, although it should be pointed out some premium EV rivals offer service intervals which are twice as long, and even free servicing for the entire warranty period.

The RX350h is covered by a five-year, unlimited-kilometre warranty, and the servicing schedule is every 12 months or 15,000km.

There’s a capped-price servicing plan lasting five years and it will cost $695 per service. That's significantly less than some rivals like the Mercedes GLE.

The RX is covered by the 'Lexus Encore' loyalty program and includes complimentary service loan cars, fuel offers as well as discounts and other offers with Lexus partners.
