Lexus Rz vs Toyota BZ4X

What's the difference?

Smooth, quiet, quality sums up this new and improved Lexus RZ. But will tricky new tech like steer-by-wire and a manual mode in the F Sport's auto transmission be enough to sway more premium electric SUV buyers its way? Fold in this car’s value proposition as well as the brand’s spectacular ownership package and it just might be.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

When the bZ4X first launched it was already late to the game and blended into the background too much. However, this update has dramatically improved its appeal.

Despite this, the electric mid-size SUV segment is incredibly fierce and it’s hard to not get caught up in glitzier rivals like the BYD Sealion 7, Tesla Model Y and Zeekr 7X.

It’ll be interesting to see whether the Australian public reacts to this update and if it draws in more punters.

Not a tremendous amount of change in terms of exterior design for this update with the brand’s signature angular treatment retained including a prominent snub nose and 20-inch rims on both variants of the car.

The top-spec F Sport picks up extra aero-focused elements, particularly around the lower bumper at the front, as well as aero covers on the wheels and at the back a spoiler on the tailgate as well as a faux diffuser at the bottom of the lower bumper.

Not much has changed inside either except for a steering wheel-shaped elephant in the room in the form of a yoke that goes with the steer-by-wire function on the 550e F Sport. A significant, eyebrow-raising departure.

However, the curved instrument binnacle, central 14-inch multimedia screen as well as the design of the centre console remain unchanged. 

Having said that, there are new ‘laser-patterned’ designs in the door card trims and dynamic lighting graphics in the doors, as well.

The functionality of the touch-dimmable panoramic roof has also been improved and it works beautifully.

The exterior design of the bZ4X never really blew me away. It’s just sensible and not too out there. In saying that though, being sensible is no bad thing and can be seen as a positive for some buyers.

This facelift has brought Toyota’s new corporate look, including the hammerhead shark-like LED lighting signature. It already features on models like the C-HR, Camry and RAV4. In fact this update has made the bZ4X look more like an electric RAV4 than ever before.

I like the C-shaped daytime running lights but I’m not a fan of how the main headlight section is now separate. I prefer how they looked before.

The black wheel arch cladding is now also glossy and not matte. Sure, this looks great right now, but it likely won’t be long until it unfortunately gets scratched.

Inside, if you covered up the Toyota badge you could likely fool me into thinking this is a Lexus. The new 14.0-inch touchscreen is virtually identical to the one in models like the Lexus NX, RX and GX.

There are also plenty of premium-feeling soft-touch materials around the cabin. I’m not a huge fan of the grey and white two-tone interior, at least from a family-friendly standpoint, but thankfully you can get an all-black interior instead.

Another major design change with the interior is the new centre console. It now features two wireless chargers and a revised button layout. I particularly like it because it’s no longer covered in glossy piano black.

At a fraction over 4.8m long, close to 1.9m wide and a bit more than 1.6m tall, with a 2850mm wheelbase, the ZR is a sizeable machine. 

There’s plenty of breathing space in the front and in terms of practicality the first thing that jumps out, or rather it doesn’t, is the lack of a conventional glove box.

But there is a large box between the front seats to take its place, with the lid (which doubles as a centre armrest) performing the Lexus party trick of being able to open towards the driver or passenger.

There are two cupholders in the centre console with a wireless charging pad ahead of them, plus decent bins in the doors for bottles and other bits and pieces. An additional tray sits under the main, flying buttress-style upper console.

For power and connectivity, there are USB-C sockets for charging and media as well as a 12-volt socket in the lower console section.

Getting into the back is easy thanks to wide-opening doors and a large entry aperture and seated behind the driver’s seat set for my 183cm position I’ve got hectares of leg- and headroom. Shoulder room is best for two full-size adults rather than three, which would be a short-journey squeeze. Three up to mid-teenage kids will be fine.

In terms of storage there are pockets on the front seatbacks, bins able to hold a large bottle in the doors and two cupholders in the fold-down centre armrest. Individual ventilation control for rear seat passengers is always welcome. 

Then for power, there are two USB-C outlets and a ‘house-power’ socket underneath them. The 550e F Sport also includes heating controls for the two outer rear positions.

Lower rear axle packaging enhances boot space with a generous 522 litres on offer, expanding to 1451L with the 60/40 split-folding second row lowered. Tie-down anchors and bag hooks are a thoughtful touch and there are handy storage boxes under the flat floor, ideal for charging cables. 

The standard power tailgate is nice, while a repair-inflator kit instead of a proper spare isn’t. Braked trailer towing capacity is a handy 1.5 tonnes.

The front seats in the bZ4X are deliciously comfortable and supportive. They make long trips a breeze, plus the ventilation that’s standard on the AWD trim works well in the heat.

Despite this, I’m still not a huge fan of the driving position. You need to look over the steering wheel in order to view the almost windscreen-mounted digital instrument cluster. It’s a similar set-up to what Peugeot employs and is intended to reduce the amount you need to stray your eyes from the road.

I appreciate this but it just doesn’t work for everyone. Personally I need to jack the seat up more than I’d like in order to see the screen fully. When I do this my knees get in the way of the steering wheel no matter how I position it, which isn’t ideal.

The set-up in the related Solterra is a little better as it has a squared-off steering wheel instead of a traditional round steering wheel.

Going back to the digital instrument cluster, the content display on this is still rather limited. Thankfully, critical information like your current speed is displayed clearly, but having added customisation through more informative displays to toggle through or more themes would be a nice extra touch.

Moving across the larger touchscreen multimedia system is a welcome addition, but I didn’t think there was anything wrong with the old one. The user interface is still basic in a good way, meaning it’s hard to get lost.

A difference is the climate control features are now fully integrated into the touchscreen, save two physical dials that change the dual-zone climate control temperature.

While this means you need to press on the touchscreen to change certain climate control-related features now, a lot of these in the pre-update were touch-sensitive buttons on a panel under the touchscreen. Really, it makes no difference.

Wireless Apple CarPlay and Android Auto are still standard and work flawlessly with my iPhone 15 Pro Max. There are now also two wireless chargers, which is great if you want to charge your phone and your passenger’s phone.

However, they don’t work properly as they don’t offer any ventilation. They regularly make my phone overheat and stop charging, even on shorter trips. If you want to reliably top your phone’s battery up, it’s best to just plug into a USB port with a cable.

Looking elsewhere around the cabin, there is an adequate amount of storage, though some more would be nice. There are two decently sized cupholders, a small shelf under the centre console and a side-hinging centre console box. Like the pre-update version, there is still no proper glove box.

In the second row there’s plenty of legroom available for adults behind adults, though due to the placement of the high-voltage battery this leaves you with a knees-up feeling. This is common in a number of EVs, even some that are based on dedicated electric architectures, like the bZ4X.

Headroom also isn’t fantastic as the roof starts to taper back where your head is located. You wouldn’t want to be much taller than 180-odd centimetres back there. It’s also made worse when you recline the seat backrest.

Second-row amenities include air vents, heated outboard rear seats, USB-C ports, seatback map pockets, as well as a fold-down armrest with some cupholders and a tablet holder.

At the back there is a hands-free power tailgate which is rather slow to open and close and makes plenty of beeping while doing so. It's a classic Toyota on this front.

The bZ4X AWD offers 410L of boot space with the rear seats upright which is slightly less than the 2WD due to the added rear electric motor.

It’s a decent space but doesn’t stand out from the crowd. There’s some extra underfloor storage which is large enough to fit some cables and that’s about it. Unfortunately there’s no front boot.

Boot-related amenities include a cargo blind, a variety of hooks, as well as vehicle-to-load (V2L) capability using 220V/1500W AC inverter and a single household power socket. The latter allows you to power household appliances using the vehicle’s high-voltage battery.

Disappointingly there is no spare wheel, but this isn’t uncommon for EVs. You have to make do with a tyre repair kit, which is fine if you have a small air leak but pointless if you have a proper puncture.

There are still only two trim levels in the bZ4X line-up – 2WD and AWD, the latter on test here.

Compared to the pre-update version, pricing has been slashed by up to $10,000, depending on the variant.

The line-up now starts at $55,990, before on-road costs, for the 2WD and extends to $67,990, before on-road costs, for the AWD.

This top-spec bZ4X AWD now undercuts the corresponding Subaru Solterra AWD Touring by $2000. These two cars are twins under the skin and are built in the same Japanese facility.

It also undercuts the top-selling Tesla Model Y Long Range AWD by $1000, which is a major feat. However, certain rivals like the BYD Sealion 7 Performance and Zeekr 7X Long Range are still cheaper but not all of them offer all-wheel drive.

With this update there’s now a larger 14.0-inch multimedia touchscreen, two wireless phone chargers, vehicle-to-load (V2L) capability, plus a hands-free power tailgate and heated steering wheel standard across the line-up.

This is above and beyond the standard LED headlights, roof rails, dual-zone climate control and heated front seats with electric adjustment in the 2WD.

The AWD brings larger 20-inch alloy wheels, a panoramic glass sunroof, a nine-speaker JBL sound system, digital rear-view mirror and ventilated front seats.

This is a lot of standard equipment and you can’t really complain because you’re getting all of this for less than before.

Both versions of the new RZ are powered by dual permanent magnet synchronous motors, one in the front, one at the back, each producing 167kW and 269Nm. 

Total output is 280kW for the 500e (up from 230kW in the 450e), with a little more juice released from the motor combination for the 550e at 300kW.

A single-speed transmission sends drive to both axles and the RZ550e F Sport features ‘Interactive Manual Drive’ designed to give the sensation of manual gear shifts in a BEV. More on that in the Driving section.

While there have been a number of spec changes or additions with this update, even more tweaks have happened under the skin.

All versions of the bZ4X now make more power and torque. The AWD’s dual electric motor set-up now has a total system output of 252kW (+92kW) and 438Nm (+101Nm).

Like the pre-update version, the bZ4X AWD offers 'X-Mode' off-road drive modes, crawl control, as well as downhill assist control. However with 20-inch alloy wheels as standard, I doubt these will be taken off the beaten track very often, if at all.

The RZ500e and 550e are fitted with a 77kWh lithium-ion battery delivering a claimed (WLTP) range of 450 and 456km, respectively.

Claimed 10-80 per cent charge time, using its full 150kW DC fast-charge capacity, is 30 minutes or a handy three and half hours at maximum 22kW AC capacity.

Energy consumption on the combined (urban/extra-urban) cycle is 18.2kWh/100km (WLTP) for the RZ500e and 18.4 for the 550e.

Over several hundred kilometres of B-road and freeway running as well as pottering through slow-speed villages on the launch we saw an average of 19.3kWh/100km in the 500e and 20.1 in the 550e F Sport, which is pretty handy.

And the (very) good news is two AC charging cables, installation of a home charger and three years’ complimentary charging across the Chargefox network is included. Nice!

Another big under-the-skin change with this update is Toyota has fitted the bZ4X line-up with a larger 74.7kWh lithium-ion battery pack.

As a result this EV has more range. The AWD now offers up to 517km of WLTP claimed range (up from 411km) with an official energy consumption figure of 16.0kWh/100km.

During my largely urban testing over the Christmas break I saw an average energy consumption of 14.4kWh/100km. In fact, on one particular trip into the city with minimal traffic I saw an average energy consumption of 10.5kWh/100km. This is incredibly low for an all-wheel drive EV and almost Tesla-like.

Using my as-tested energy consumption figure, the bZ4X AWD has a theoretical total range of 518km.

The Type 2/CCS combination charge port remains on the left-hand front wheel arch which is fine because it’s kerbside, but at some public charging stations it can be hard to connect the cable without having it run up against the front bumper.

Speaking of charging, the maximum AC charging rate has now been upped all the way from 11kW to 22kW, which is a fantastic update. This now allows for a 10 to 100 per cent charge in 3.5 hours.

While peak DC fast-charging unfortunately is still capped at 150kW, Toyota claims it can remain at a higher charge rate for longer now thanks to reworked battery thermal technology.

A fast charge from 10 to 80 per cent is now meant to take 45 minutes. It would be good to see quicker charging because many of this car’s rivals are faster and this can make a world of a difference during long road trips.

It’s a hefty machine at 2.1 tonnes, but Lexus says the RZ550e F Sport will accelerate from 0-100km/h in 4.4 seconds, with the 500e only marginally slower at 4.6sec.

In straight-line acceleration Lexus says front to rear power distribution varies between 60:40 to 100 per cent rear to suppress pitching and “produce a more direct acceleration feel”. 

And the RZ is indeed quick. Apply your right foot at just about any speed and the car rockets ahead with satisfying enthusiasm.

The F Sport’s ‘manual’ mode allows you to shift through eight virtual ‘ratios’. Press the ‘M’ button on the console and bingo, you have slim steering wheel-mounted paddles to control them.

At anything above a light accelerator application you’ll feel a jolt on upshifts, but it’s rather unpleasant. Sure, you want some sense of a gear change, but you feel it in your core. Check out the video review to see how much it can shake you around. 

A synthetic soundtrack Lexus refers to as the “BEV Sound”, vaguely echoing an internal combustion engine, is fed through the F- Sport’s audio system and it feels thin and brittle to our ears. Again, check out the audio sample in our video review to see if you agree.

You’ll hear the ‘revs’ rising on up and downshifts but there’s no physical accompaniment with the latter as far as we could sense.

Suspension is strut front with double wishbones at the rear and it’s been given a thorough revision in terms of dampers, springs and bushings in both the 500e and 550e F Sport, with the latter copping some additional fine-tuning in each of those areas.

We sampled 500e and 550e F Sport versions of the RZ on the launch drive in Southern Portugal, covering mostly Aussie-compliant roads with lots of bumps and ruts to deal with. And despite its hefty kerb weight the car copes with these imperfections well.

There’s also been some extra attention paid to body rigidity in this updated RZ, specifically reinforcement of upper sections of the nose and around the boot to keep the car more torsionally stiff.

In cornering the drive distribution ratio is between 80:20 front to rear to RWD-only, according to vehicle speed and steering angle, and the car feels composed and predictable.

The F Sport features the steer-by-wire system, using a yoke rather than a conventional steering wheel and the ratio is such that all you have to do is turn the wheel slightly to generate a response.

It’s smooth and progressive but quick at the same time. You soon become used to it.

While it's unusual to see a small yoke in your hands rather than a steering wheel, it means you have an uninterrupted view through to the instruments, which is a nice side benefit.

However, much like the Infiniti Q50’s system before it, there is no mechanical link between the driver’s hands and front wheels. Steering inputs are relayed by electric signals from a torque actuator to a control actuator.

So, while Lexus says “important feedback filters through without the unpleasant vibration effects of a mechanical connection”, and that’s true, by definition there is no road feel and the wheel feels numb from that point-of-view. Worth noting the mechanically steered 500e feels much the same.

Tyres are Dunlop SP Sport Maxx (235/50 fr - 255/45 rr) which grip hard and remain relatively comfy despite their short sidewall running on 20-inch rims.

One price you pay for the steer-by-wire system’s set-up is a substantial turning circle, so be ready for that.

Braking is by ventilated discs all around, which work nicely, and when you’re not using the manual mode in F Sport the steering wheel paddles allow movement through four levels of regenerative braking.

The most aggressive setting will slow you quite markedly but not to the level of ‘single-pedal’ operation.

Additional sound insulation includes an under-seat rear floor silencer, soundproofing in the door trims as well liberal use of damping sheets, foam, silencer pads, insulators and extra seals. And the car is super-quiet, even for an EV.

In terms of miscellaneous observations, the front seats on both versions remained comfortable and supportive over long stints behind the wheel (and yoke!).

Slow speed manoeuvring is assisted by a 360-degree overhead camera view with a translucent trace of the car in the centre, as well as a high-quality reversing camera. Vision across the car and through to the back is good, anyway, but the extra tech helps in the slow speed stuff. 

There’s also a sensible mix of physical dials and on-screen controls and the touchscreen menus are easy to use. Especially handy when you’re racing to the function that turns off the intensely annoying over-speed warning.

The bZ4X AWD was never a slow car to begin with but the added oomph is welcome.

While it's not overtly noticeable in everyday driving, when you mash the throttle at the lights you're pinned back in the seat a lot more than before.

Despite this, it still doesn’t feel like this car wants to be driven quickly. If you drive with a docile right foot, the bZ4X is a supremely comfortable vehicle that’s relaxing and easy to drive.

There are a number of regenerative braking modes to select from by using the steering wheel-mounted paddle shifters, but none of them offer a one-pedal driving mode. This means you need to use the brake pedal to come to a complete stop.

As a result, this car’s driving experience is more like a combustion or hybrid vehicle, like the RAV4. This can make the transition to an EV easier if you’ve never driven one before.

The steering feel in the bZ4X has a noticeable weight and heft to it which feels nice when you’re zipping around on urban streets. It also feels like the steering wheel is actually connected to the wheels rather than the overly assisted and light steering systems in some of its rivals.

Where the added steering heft can feel a touch annoying is when you’re doing a tight parking manoeuvre. This car is longer than you think, meaning you may need to do three-point turns more often.

Speaking of parking, the bZ4X’s surround-view camera system is detailed and high-resolution, which is a great peace of mind. The semi-autonomous park assist is also fantastic as it can detect and park the vehicle within painted lines, rather than just slot it between two parked vehicles.

Adding to the comfort factor is this car’s ride, which is a major highlight. Despite the large 20-inch alloy wheels, the suspension does a great job at softening bigger bumps and small road imperfections.

There is little that upsets the interior ambience in this car, making it a serene place to be regardless of where you’re travelling. For an EV you’d expect more tyre and wind noise given there’s no engine to drown the noise out, but Toyota has seemingly done a great job of insulating the cabin and choosing suitable tyres.

The updated bZ4X still has a maximum five-star ANCAP safety rating based on testing conducted on the pre-update car by Euro NCAP.

Toyota has notably now made the full safety suite standard across the entire line-up. 

Previously the 2WD missed out on features like blind-spot monitoring and a surround-view camera, among others.

As standard there are eight airbags, autonomous emergency braking (AEB), rear cross-traffic alert, lane-keep assist, adaptive cruise control, driver attention monitoring and traffic sign recognition.

There’s also connected services with SOS emergency calling, plus automatic collision notification, vehicle insights and charge station search available with a smartphone companion app.

All of the safety systems operate in a seamless manner and don’t interrupt the driving experience unless they actually need to. This is becoming increasingly uncommon.

The RZ is covered by Lexus Australia’s five-year/unlimited km warranty and there’s an eight-year/160,000km warranty on the drive battery, which is in line with the RZ’s key competitors.

Recommended maintenance interval is 12 months/15,000km, which is relatively brief for an EV. 

Capped-price servicing is yet to be confirmed, but for reference the outgoing 450e runs to $395 for each workshop visit up to a maximum of five years/75,000km. That’s sharp pricing in this part of the market.

The RZ also qualifies its owner for ‘Platinum Electrified’ benefits under the ‘Lexus Encore’ ownership program. That means everything from access to “exclusive offers and events” to a complimentary service loan car, five years’ roadside assistance, valet parking at selected locations, airport lounge access and (heaps) more, including the charging benefits mentioned earlier. Hard to argue with that.

As standard there is a five-year, unlimited-kilometre warranty which is fine but does not stand out for the segment anymore.

However, if you service at one of Toyota’s 260+ dealers around Australia when required, warranty coverage for the high-voltage battery can be extended all the way out to 10 years.

Logbook servicing is required every 12 months or 15,000km, whichever comes first, and the first five services are capped at $180 each. While the pricing in classic Toyota fashion is competitive, the 12 month intervals aren’t (in the EV space). The standard is now closer to 24 months.

As part of the ownership package owners get Mode 2 and Mode 3 charging cables. The 'Toyota Go' loyalty programs also allows for the choice of a complimentary 7.0kW home charger or 12-month Chargefox subscription.
