Lexus RZ450E vs Smart 1

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 easy to get lost in marketing hype, but — based on first impressions — the Smart #1 does what it says on the tin. This is a Chinese-built SUV that feels more premium than most, and one which is priced to tempt you from one of the German big three. The warranty isn’t good enough, though, and the multimedia screen can be infuriating, but it drives very nicely, especially on suburban roads.

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

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.

There is an impossibility pretty model in Smart’s new line-up, but the #1 ain’t it. While the #3 — which has also just launched — is a sleek-looking, coupe-style SUV, the #1 is a top-heavy small SUV that doesn’t shine from every angle.

Front-on, or from a front three-quarter angle, the #1 definitely works, with the brand setting out to remove unnecessary fussiness from the design, leaving smooth and rounded bodywork in its place.

There are no body creases or weird angles here, instead it’s a smooth, fluid-like design that flows from the front LED lights bar to the smooth shoulder lines to the matching light treatment at the rear. 

But it’s at the rear where, for mine, the design begins to fall over. From that angle, the #1 looks skinny and top-heavy, especially when wearing the red hat of the Brabus model.

Still, eye of the beholder and all that.

Inside, though, the #1 kicks all sorts of goals, presenting as a properly premium-feeling EV space that’s swimming with technology and lovely cabin materials.

I particularly love the letterbox-style screen that replaces the traditional dashboard. It’s not distracting or overbearing like some twin-screen set-ups, but clearly shows you the key driving stuff you need when you’re on the road.

Side note, though, the massive central screen is super clear and lightning fast, but as usual you need to spend some (a lot) of time with it to figure out where all the functions are hiding, with most of the car’s key controls hidden within its labyrinth.

And side note two, the background graphics look like they were designed by a cordial-addled child, it is busy, cartoonish and out of keeping with the calm, grown-up nature of the #1’s cabin.

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 Smart #1 measures just under 4.3m long, just over 1.8m in width and around 1.6m in height, and it rides on a 2.75m wheelbase. And the perk of the Smart’s EV powertrain, the brand says, is Mercedes-Benz E-Class levels of space in the back seat, despite the #1’s diminutive footprint.

It’s a big claim, and while I didn’t break out the tape measure I can say the backseat feels plenty generous, and because the rear pew slides forwards or backwards by 15cm, you can choose whether you want more legroom or more luggage space.

Speaking of which, pop the auto-opening boot (by hitting the ‘a’ in the ‘Smart’ lettering, which I couldn’t figure out without help) and you’ll find 323 litres of space with the back seat as far back as it goes, growing to 411 litres with it pushed all the way forward. There’s also a 15-litre frunk.

Smart says the #1 weighs 1800kg, adding it will tow 1600kg — but I’m sure you can imagine the impact a heavy load will have on your driving range.

The #1 is available in three trim levels — the Pro+, Premium and Brabus — and pricing (before on-road costs) climbs from $54,900 to $58,900 and $67,900. 

Brabus, by the way, was a lesser-known Mercedes-Benz tuning arm, a little like AMG, which should give you some idea of what to expect from the performance-badged models.

Anyway, that pricing is good enough to undercut key rivals, including the Volvo EX30 (from $59,990) and BMW iX1 ($78,900), and it’s drastically less than Mercedes-Benz's EQA 250 ($84,900), all before on-road costs.

Also firmly in the Smart’s favour is that there isn’t a cheap-feeling model among them, with even the Pro+ feeling properly well-equipped and premium.

Entry-level cars score 19-inch alloys, a panoramic roof, LED lighting, a powered tailgate and a 12.8-inch central screen with wireless Apple CarPlay and Android Auto, and a 9.2-inch digital dashboard. There’s wireless device charging and a decent stereo, too.

The Premium then adds matrix LED headlights, leather trim, a huge head-up display and a better Beats stereo, while the Brabus scores a unique interior and exterior treatment, better suspension and a launch control function.

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.

There are two drivetrains on offer here - one shared across the Pro+ and Premium, and another delivering the prodigious power of the #1 Brabus.

The first shared option is a single rear motor that delivers 200kW and 343Nm, which is enough to knock off the sprint to 100km/h in 6.7 seconds. Top speed for all models is listed as 180km/h.

The Brabus, though, adds a motor at the front axle, giving it AWD, which ups the outputs to a punchy 315kW and 543Nm, dropping the sprint to 100km/h to a very fast-feeling 3.9 seconds.

It’s a single-speed EV transmission in each, which means smooth, constant power delivery with no traditional ‘steps’, and all get 'Eco', 'Normal' and 'Sport' drive modes, though the only thing they impact is the accelerator response.

You can add weight to the steering, but that’s a separate item accessed elsewhere in the screen’s sub-menus.

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.

All Smart #1 models share the same 66kWh battery, but how far you can travel between charges comes down to the trim you choose, with the WLTP driving range either 400km, 420km or 440km. The Brabus, of course, covers the least ground between charges, owing to its dual-motor set-up and amped up power outputs. 

When it comes time to plug in, all models are equipped with 150kW DC fast-charging capability, and when plugged into said charger, you can expect to go from zero to 80 per cent charged in less than 30 minutes. 

There’s also 22kW AC charging on board in the Premium and Brabus models, which means you can use three-phase power, but plugged into a regular 7.4kWh home wallbox should see you go from zero to 80 per cent charged in 7.5 hours, which means overnight charging should work a treat.

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 #1 and its sister car, the #3, might share powertrains and batteries, but they are designed to drive very differently. The #3 is the sporty one (always code for a firmer ride), while the #1 is supposed to be softer, more comfortable and more city-friendly.

That’s the theory, at least. In practice, I have no idea. My time behind the wheel of the #1 was limited to its most fire-breathing model — the Brabus, which also scores its own suspension components — and soft is not a word that comes to mind once you’re strapped in behind its bright red seatbelt.

It begins with those bonkers power outputs, 315kW and 543Nm, which deliver genuine push-you-back-in-your-seat acceleration every time you stand on the go pedal.

Better still (well, I think so, at least), is that activating its sportiest 'Brabus' mode also unlocks a deep Abarth-style burbling soundtrack that rises and falls with your inputs.

But like most performance EVs, you can also dial the drive experience right back. In its softer drive modes the #1 Brabus feels calm and comfortable and not overly reactive, which makes sense, given the only thing the Brabus mode changes is accelerator sensitivity.

The result, though, is a car that you can tootle around in silently when you want to but hides a nuclear weapon under your right foot when you want to unleash that part of its personality. 

Downsides? It’s got plenty of point-and-shoot power, but in the few corners we managed to find in it, it didn’t quite live up to the all-out-performance badge. There’s a bit too much movement in the body — a symptom of its near-2.0-tonne weight — and it doesn’t feel entirely engaging.

A couple of important caveats, though. We didn’t get long behind the wheel of the #1, and the dull-as-dishwater prescribed drive program revealed little about its true performance potential. So, we’ll have to wait until the model is properly through the CarsGuide garage to give you a deeper dive on this one.

Full credit to Smart on this one, because the #1 comes with a pretty stacked active (crash avoidance) safety tech list, and though our test drive was far from exhaustive, only the speed limit warning (which you can switch off) felt overly intrusive, with the rest just sort of humming away in the background.

The full package includes things like adaptive cruise control, lane keeping assist, traffic-sign recognition and the aforementioned speed limit warning. There’s also AEB, along with seven airbags, all of which has earned the #1 a five-star Euro NCAP safety rating.

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.

Warranty is a definite soft spot, with LSH Auto offering five years or 150,000km, whichever comes first. For reference, other Chinese newcomers include Chery (seven years) BYD (six years) and GWM (seven years), while MG has just shifted to a 10-year warranty.

Still, service intervals are 12 months/20,000km, and you should be able to take your Smart to any LSH Auto Mercedes dealership (in Melbourne, Brisbane and Sydney) or either of the Smart dealerships in Sydney or Brisbane.

Service cost for the first four years averages $611 per workshop visit for the Pro+ and Premium (worth noting the fourth service is a big one) and $780 for the Brabus. Not particularly small numbers.
