BMW IX1 vs Lexus RZ450E

What's the difference?

BMW is a true EV pioneer, as the 2014 i3 and subsequent models prove. There’s never been one that we didn’t like. The only problem was that all were expensive. And at times, prohibitively so.

Astoundingly, the iX1 breaks that cycle, comparatively speaking, while impressing us with its design, quality, packaging, dynamics and equipment levels.

As it stands, the xDrive30 is one of the most convincing and best-value medium-sized luxury SUV EVs on the market right now.

Who’d have thought it from a BMW?

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.

Arguably the prettiest new BMW SUV you can buy today, the well-proportioned iX1 is nearly impossible to spot over its almost-identical ICE (U11) X1 siblings.

Besides the badging, look for some blue trim bits and pieces inside and out, along with additional digital touchpoints inside.

And while both ride on the same all-new platform that’s resulted in a substantially larger body compared to previous X1 generations, the EV version seems a bit more slammed.

Dimensionally, the iX1 mirrors today’s X1 at 4500mm long and 1845mm wide, and still sits on the same 2692mm wheelbase, but is 26mm shorter at 1616mm tall and offers 35mm less ground clearance at 170mm.

Result? These plus a bunch of aero enhancements mean the slipperiest iX1 manages a Cd of just 0.26, according to BMW.

And, inevitably, the extra size equals more space inside.

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.

BMW also says the iX1’s cabin is almost as roomy in some ways as the larger X3.

Large doors allow for easy entry and egress, onto sumptuous front seats that provide exceptional comfort and support even on longer journeys.

Surrounded by an expansive feeling of space, the interior feels light and airy, as well as fresh, inviting and premium looking – something previous-gen X1s were rarely accused of being.

We’re talking on-brand stuff here, beginning with the excellent driving position, ahead of a crisp and attractive dash that’s pleasing to behold. Push-button starting and a small toggle lever operates the transmission.

An ever-so-slightly curved (towards the driver in the best-BMW old-school way) rectangular binnacle houses two digital displays – a 10.25-inch one ahead of the driver offering an array of configurable electronic dials, as well as a 10.7-inch multimedia touchscreen.

BMW pioneered the multimedia controller more than 20 years ago with iDrive, and this descendent of that system reveals all that expertise gained by being intuitive to operate and quick to respond to commands once familiarised. Which shouldn’t take too long.

It’s all very-EV centric, as the industry inexorably moves to total electrification, but there were a couple of voice-command errors in the iX1, revealing that such systems are still far from perfect. BMW does provide audio volume and climate hard buttons, thankfully, so the basics are looked after.

Speaking of which, the iX1 offers decent levels of vision out, superb ventilation and ample storage in the doors, on the dash and between the front seats. And, as we’ve noted previously in BMWs, the upright smartphone charger is a clever idea. Keeps it in position and is handy to glance at.

Out back, backrest comfort and support is A-OK, and even with the optional sunroof, our test iX1 provided sufficient space for taller bodies, while expected items like ventilation grilles, USB ports and cupholders are fitted.

Note that, though the 40/20/40-split backrests recline slightly, they do not slide as per in the ICE X1, as this is a desirable option.

Nor is the cargo capacity as good in the iX1, due to the inevitable space demanded by that rear-axle-mounted electric motor and battery pack. For the record, ranges from 490 litres to 1495L instead of 540-1527L. Plus, there’s no spare tyre, with just a tyre repair kit fitted.

These aside, the iX1’s spacious and inviting interior remains one of the compact SUV segment’s best.

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 RZ arrives in Australia in just one 450e all-wheel drive variant, with two trim levels to pick from. Either the entry-point Luxury grade ($123,000, before on-road costs), or the top-spec Sports Luxury ($135,000, before on-roads). 

It’s entering a hot market, which every luxury brand wants a slice of. Rivals include the outgoing Audi e-tron, ($138,323) which is set to be replaced by the presumably more expensive Q8 e-tron imminently, base BMW iX ($135,900), Genesis GV70 Electrified ($127,800) or the smaller GV60 ($107,700).

Soon it will also have to duke it out with the Polestar 3 which is higher performance, starting from $132,900, and there’s always the spectre of the Tesla Model Y, which is a comparative bargain at $98,415 for the go-fast Performance version.

In terms of premium-badged rivals, though, it’s at the lower end of the price-scale, following the Lexus model of providing relative value in its space.

The entry-level Luxury grade comes standard with 18-inch alloy wheels, LED headlights and tail-lights, a massive 14.0-inch multimedia touchscreen with Apple CarPlay and Android Auto connectivity, built-in sat-nav, connected services, wireless charging, a digital instrument cluster, synthetic leather interior trim, dual-zone climate control, push-start ignition with keyless entry, a 360-degree parking camera, a 10-speaker premium audio system, and the full safety suite. More on that later.

For the extra spend to get into the Sports Luxury grade, the wheels are upgraded to massive 20-inch units, then you can count on adaptive headlights, acoustic glass, contrast styling panels on the exterior (with a two-tone paint option), ‘ultrasuede’ interior trim with ‘Tsuyasumi’ ornamentation, interior LED ambient lighting, an electrochromatic sunroof, ventilated and heated front seats with infra-red ambient heating for front passengers, rear outboard heated seats, memory driver’s seat, a head-up display, touch-sensitive wheel controls, and a 13-speaker Mark Levinson audio system.

Some of these features are very cool. The sunroof and ultrasuede interior trim options with the detailed ornamentation, and even wacky carpet trim in the Sports Luxury grade, are enough to take you aback, helping this Lexus make its mark on the luxury mid-size EV market. 

Will it be enough to offset some notable omissions like the lack of vehicle-to-load systems or household power outlets on the interior?

This will depend on the buyer, but I think objectively this Lexus is playing into its existing loyal customer base more than it is the new-age tech savvy buyer.

The iX1 boasts BMW’s fifth-generation EV drive system, known as eDrive 5.0 (M170SF).

Being an xDrive30, there are two electric motors fitted – one on each axle to provide all-wheel drive. Both are electrically excited synchronous motor set-ups.

Drive is predominantly to the front wheels via a single-speed reduction gear transmission, unless extra traction is required, in which case the rear motor kicks in to power the back axle.

Combined with the aid of an overboost function, they deliver 230kW of power and 494Nm of torque, for a 0-100km/h sprint time of 5.6 seconds, on the way to a 180km/h top speed.

Tipping the scales at 2010kg, the xDrive30 provides a power-to-weight ratio of 114kW per tonne, which is a healthy number.

Suspension is via MacPherson-style struts up front and an independent three-link design out back.

If you care, towing limits are 1200kg braked and 750kg unbraked, with a 570kg maximum payload.

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.

BMW says the xDrive30 consumes an average of 18.3kWh/100km.

On the launch drive program, the vehicle displayed 21.3kWh/100km. That included some spirited highway and mountain-road driving conditions.

Fitted with a 67kWh lithium-ion battery pack with a useable 65kWh, the iX1 offers an ADR 81/02-rated range of 400km.

This means a relatively common 50kW DC public charger with a CCS Combo 2 socket will need about 65 minutes to replenish the battery from 10 to 80 per cent or about half an hour with a 150kW charger.

If neither are available, you'll require about 34 hours to charge to 100 per cent maximum using the normal household powerpoint plug. Or, as mentioned earlier, a 22kW AC Wallbox cuts that down to about 3.5 hours.

Each iX1 includes a three-year subscription with Chargefox.

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.

One of the best things about the iX1 xDrive30 is that it has just enough EV smoothness, refinement and speed to feel special, yet still drives and behaves as a BMW should.

Which hasn't always been the case with previous-gen X1s.

It helps that, from the driver’s seat, everything falls into place: the bracing seats, thoughtfully positioned relative to all controls; and the overall sporty/quality ambience that puts you into the brand mindset.

Select Drive, and the iX1 leaps away sweetly and silently, accompanied by an electric motor whir that's quite pleasing. At speed, acceleration is instant for fast overtaking and there’s plenty more in reserve if you really need to hustle along.

For a 2.0-tonne compact SUV, the steering is remarkably responsive, providing nimble yet secure handling. Maybe it’s all the low-slung weight and near-50:50 weight distribution, but the iX1 displays impressive cornering and road grip. It’s an enjoyable drive.

Initially, novices might find the brakes a bit sudden, but they’re actually pretty progressive once you get used to them, and they feel and stop with a more natural pedal feel than many hybrids we’ve experienced. Again, BMW has tuned the xDrive30 to feel inclusive.   

Speaking of the stoppers, there are no paddle shifters to control the amount of single-pedal off-accelerator braking as per many other EVs, but putting the transmission from ‘D’ to ‘B’ brings a decent level of deceleration if not a full stop – as if you’re lighting resting your foot on the pedal. We’d like the option of a heavier self-braking function, though.

The launch program avoided city roads and heavy traffic, but we still found plenty of bad, pot-holed surfaces to favourably judge the adaptive dampers’ ability to help soak up the bumps.

While not super-soft or supple, the suspension is cushy enough for a comfy ride. And certainly better than many past BMW SUVs.

A bit too much road and tyre noise intrusion aside, the xDrive30 is dynamically very sorted indeed.

Which, when you consider all the other positive aspects of the iX1, you end up with a BMW offering an impressively broad band of capabilities.

It’s rapid, nimble and reactive to driver inputs, as you’d expect an SUV from this brand to be, without the compromise of harshness or discomfort.

What it’s like around town in a peak-hour crawl, or how far you can really get from a fully-charged battery, is something we’ll find out when we can conduct a full road test, so please watch this space.

Until then, as it stands, things are looking promising indeed for the xDrive30. Especially factoring in the value pricing.

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.

Safety comes standard on the Lexus RZ, with even the base Luxury trim-level scoring high-speed radar-based auto emergency braking (which detects vulnerable road users at night), lane keep assist (with lane departure warning), blind-spot monitoring (with rear cross-traffic alert), as well as driver attention alert, adaptive cruise control, and a tyre-pressure monitoring system as standard.

The only item reserved for the higher-grade Sports Luxury is the advanced adaptive high-beam suite.

The RZ also scores an impressive complement of 10 airbags, as well as the most recent crash structures in its fresh e-TNGA frame, however the EV mid-sizer is yet to be rated by either ANCAP or Euro NCAP.

Last year, BMW introduced a five-year/unlimited kilometre warranty with all its products, finally catching up with the industry warranty average after a protracted period of just a three-year coverage.

While there’s no capped-price servicing, you can pre-purchase a number of service bundles, to help save a bit more money further down the track.

There's a choice of 'Basic' or 'Plus' packages, in four or six-year (both with unlimited kilometre) programs, known as 'Service Inclusive'. They cost $1263/$4784 and $1800/$5784, respectively. 'Plus' covers brake pads/discs and wiper blade rubbers.

Note, however, that roadside assistance remains at three years.

Keep in mind, too, that BMW vehicles have a self-diagnosis feature that varies the service intervals according to how they’re used as well as wear and tear.

Our advice is to keep making an appointment annually or at about every 10,000km, just to be on the safe side.

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.
