Lexus RZ450E vs Mercedes-Benz Eqe300

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.

The Mercedes-AMG EQE53 SUV has some serious tech inside and will fit the family in style. If you're after the AMG experience, you may be a little disappointed as this model leans heavily towards plush rather than sports-SUV. And it does plush extremely well but it begs the question whether the AMG factor is worth the extra cash.

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.

We affectionately nicknamed our test EQE53 model the Blue Tic Tac because of its… well, similarity to the mint.

While not uncommon in the EV market, the EQEs pillowy design doesn't exactly scream 'big personality'. However, it does feature some cool features like the massive 22-inch alloy wheels, red brake calipers and the AMG badging at the rear. But that's all that separates it from its non-AMG siblings.

Head inside and it features all of the plush comforts and styling you’d expect from a Merc with some of the best ambient lighting in the business and a sunroof that manages to make the cabin feel airy despite all the black trims. 

Some of those trims, like the synthetic grey panels scattered liberally throughout the cabin, are found in all EQE models and don't reflect the grade level. A trim with better tactility and style would be a point of difference.

The dashboard features three screens in a ginormous panel, which surprisingly doesn’t catch the light but does show fingerprints and every spec of dust on it. Which might annoy you as it's 100 per cent the drawcard for the interior and when it's dirty, it's very obvious.

Although I'm not in love with some design choices, it's still a lovely cabin to spend time in.

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 cabin of the EQE53 offers plenty of head- and legroom for its occupants. Using the armrests is also a civilised affair as there's not fighting for elbow positions!

Access to both rows is (annoyingly) more complicated than it needs to be because of the sidesteps - which are, quite frankly, useless on a car like the EQE. They hit your shins/calves when you're not using them and using them feels silly.

All seats offer a tremendous amount of comfort but the fronts benefit from heat and ventilation functions that keep you relaxed year-round. They extend everywhere you need them to to get into the best seating position.

Storage is excellent throughout the car and in the front there's an extra-deep middle console (it swallows most of my arm), a large centre console that features retractable cupholders and a big shelf underneath for bulky items, like a handbag, or as my mum joked, Saturday night’s takeout and a bottle of wine!

Each door pocket gets a dedicated bottle holder and the rear also gets two retractable cupholders and a pair of map pockets.

The boot has 520L of capacity available which is a good size for the class and the wide boot aperture and level loading space make it easy to slide things in and out. You miss out on underfloor storage in the EQE53 model but the back seat has a 40/20/40 split to open up storage options.

The technology looks daunting but is very user-friendly once you spend some time with it. The main multimedia system is responsive and you can access the menus from the steering wheel controls as well as the touchscreen.

The system has wireless Apple CarPlay and Android Auto and satellite navigation, all of which are easy to use. Charging is good with eight USB-C ports (six up front!) and a wireless charging pad.

Despite having four co-pilots this week, the additional screen in front of the passenger remained mostly unused and ended up being more of a novelty.

The real bugbear has been the air-conditioning system. Despite having a pre-climate function, it takes ages for the car to cool down and my eight-year old struggled in the rear the most. The rear vents just don't seem to pump much out, even on the top speed setting.

Once the system has cooled the cabin, though, it's like a fridge. But until it does... you really notice the 30+ degree days!

The EQE SUV is available in three grade levels and the EQE53 model on test for this review here is the creme de la creme, tucking in under AMG badging, and all that implies. Sitting at $191,900, before option packs or on-road costs, positions the top model in between its high-performing electric rivals, the Audi SQ8 e-tron at $173,090 MSRP and the BMW iX M60 at $228,400 MSRP.

Our test model has the optional 'AMG Dynamic Plus Package', which adds $5691.40 to the price tag but includes a bunch of features AMG-lovers will appreciate. Items like an 'AMG Sound Experience' which gives you three motor soundscapes to choose from, a track pace function, improved motor outputs and a boosted top speed of up to 240km/h.

In terms of technology, the not-so-standard fare includes a seriously cool-looking multimedia display consisting of a 3D Burmester surround sound system and three digital screens covering the width of the dash.

The tech is rounded out by wireless Apple CarPlay and Android Auto, satellite navigation, four-zone climate control, eight USB-C ports, a wireless charging pad and digital radio.

The top model also gets some luxuries like heated and ventilated front seats featuring a three-position memory function, electrically extendable under-thigh support and a 'kinetic' function (think light stretching rather than massage).

The upholstery and trims are a good mix of black Nappa leather on the seats and doors (partial), as well as synthetic suede-like materials on accent panels throughout the car.

Practical items include a hands-free powered tailgate, rain-sensing wipers, keyless entry/start, pre-entry climate, dusk-sensing headlights and a park assist function to help in tricky car spots.

Overall, the EQE53 is fairly well packaged but does miss out on a few luxury extras in the second row, which is noticeable because its rivals cover this area a little better.

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.

The EQE53 is an AWD and has dual electric motors - one at the front and one at the rear.

Without the optioned AMG Dynamic Plus Package, the motors produce up to 460kW and 950Nm but with the package those outputs jump up to a staggering 505kW and 1000Nm!

That means the 3.7-second 0-100km/h sprint time also improves to 3.5-seconds. Suffice it to say, it's enough to blow your hair back and considering we have no roads in Australia you can really let this thing loose on, it's more than enough power for anyone.

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.

Non-AMG EQE models see decent driving ranges over the 500km mark, but the EQE53 has an official range of up to 485km which again positions it in the middle of its rivals. So, not bad, but a larger range would be welcome as the EQE53 is a comfortable road-tripper!

The EQE53 has a a claimed consumption figure range of 23.0 to 25.6kWh and a lithium-ion battery with a large 90.56kWh capacity.

After a week of open-roading, city-driving and not being shy in using its power, my average has been around 25.5kWh, which is solid for an electric performance SUV.

The EQE53 has a Type 2 CCS charging port which means you can hook it up to the faster DC chargers and it accepts up to 170kW on this type of system meaning it goes from 10-80 per cent in as little as 32 minutes. On an 11kW AC system, expect it to hit 100 per cent after 14.5 hours. 

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.

I really wanted the AMG EQE to be crazy-fun like its petrol-powered cousins but while it has the specs to support that wish, it never feels wild.

That's not necessarily a bad thing, just unexpected for an AMG model. The 53 is still one cool customer and its composure on the road is wonderful but it's a model that a grandparent could get into and not feel overwhelmed by. Power is smoothly delivered and when you need to take off, it responds eagerly .

Steering is firm and responsive but it’s the rear axle steering that makes the EQE53 feel nimble in the city or a tight car park despite its bulky size. It corners well, without much roll and you can tackle a winding road at speed with confidence.

The ride comfort is very good with minimal outside noises finding their way inside and the suspension is plush without feeling like you’re floating on top of the road.

The visibility is mostly good but the wide A-pillar is annoyingly in the way for my driving position and I have to duck my head around it to see clearly on roundabouts.

The 360-camera system is top notch but the camera angle turns when you move the steering wheel, which takes some time to get used to. Otherwise, the EQE53 is an easy one to park.

The EQE53 hasn’t been assessed by ANCAP yet but its siblings achieved a maximum five-star safety rating in 2023.

The top model enjoys a long list of safety features, including 10 airbags which is outstanding for a family SUV.

Other systems include blind-spot monitoring, an SOS call button, driver monitoring, safe exit warning, rear occupant alert, rear collision warning, forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, traffic sign recognition, an intelligent seatbelt warning, adaptive cruise control (with stop/go), park assist, a 360-degree view camera system as well as front and rear parking sensors.

There are two ISOFIX child seat mounts and three top tether anchor points across the second row but two seats will fit best.

None of the safety systems intrude on daily driving either, which is great.

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 EQE SUV is offered with a five-year/unlimited km warranty, which is not unusual for its grade level but it has a longer-than-usual battery warranty of up to 10-years or 250,000km.

You can pre-purchase a three-, four- or five-year servicing program. The three-year program costs a flat $2240, while the four-year program costs $3525 and the five-year option costs $4085.

All pricing is pretty competitive for the class but servicing intervals are odd at every 12-months or 25,000km as it's typical to see intervals on EVs at 24 months.
