Lexus LBX vs Mercedes-Benz G580

What's the difference?

Lexus has managed to combine two cars in one. A fast, impossibly fun back-road blaster perfect for weekends on your favourite winding roads, and a competent, compact city SUV that will easily handle urban runabout duties every day of the week.

It’s this duality that struck me the most. I would happily live with the Lexus LBX Morizo RR. 

If you need a bit of space, maybe look elsewhere. But if you’re passionate about dynamic driving, and value comfort and a premium experience, this little rocket is hard to beat.

As per the 1979 original, the current G-Class is produced by Magna Steyr in Arnie’s home town of Graz in Austria. And many fundamental things haven’t changed since then. But clearly this EV monster’s exotic electric powertrain is a huge departure.

It retains impressive off-road ability and straight-line speed. But will it hit the mark with top-end luxury 4WDers? Short story, this thing is wild, and it will be irresistible for a likely narrow band of tech-focused ‘must have the latest and greatest’ buyers. Nothing like impressing friends and family with a tank turn.

The regular LBX is a spunky little car with a lot of road presence. I’ve been a fan of the exterior design since first seeing one in the metal. Short overhangs, nuggety proportions, well designed tail-lights and a pert rear end - it all works for me.

For the Morizo RR, Lexus has wisely exercised some restraint when it comes to exterior flourishes. It is nowhere near as wildly styled as the Yaris GR, for example. And that makes sense. This is, after all, a Lexus. 

It’s a smart move, too. It’s subtle but still has intent. 

The Morizo RR gains styling tweaks unique to the grade including 19-inch forged aluminium wheels, red brake calipers, a different front and rear bumper design, a rear spoiler, air intakes front and rear and a dual exhaust.

Inside, the main differences are the inclusion of red stitching, sports seats, some unique inserts, and the use of synthetic suede on the centre console, dash and doors.

The LBX interior design is functional and premium with nice materials throughout. 

Okay, so Mercedes-Benz says, with a straight face, that “with the aim of optimising the vehicle’s aerodynamics” classic G-Class elements have been revised, including the reprofiled bonnet, ‘air curtain’ vents in the flares over the rear wheel arches, A-pillar cladding and the small spoiler on the edge of the roof.

At the same time, the 20-inch wheels are also claimed to be "aerodynamically optimised” and underneath, a 26mm underbody casing made from a mix of materials, including carbon-fibre (attached to the ladder frame with more than 50 steel screws), protects the battery from dust, dirt and rocks.

In ticking off the Edition One, car-spotters should look for black rims with blue brake callipers behind them, blue inserts in the exterior protective strips as well as black door handles and a new rectangular design box on the rear door for storing items such as charging cables, tools or snow chains. If you want a spare wheel, choose the standard model.

An optional black-panel radiator grille ($3800) features tinted lighting units as well as an animated LED light band and chrome surround. The light band can be activated as a running light or an animation when locking and unlocking the vehicle.

And it’s worth noting Mercedes-Benz and the car’s contracted manufacturer, Magna Steyr, have invested much time and many Euros in retaining the car’s classic handle and door lock design. G-Wagen owners will recognise its sound from several kilometres away.

Inside the G580 it’s clear this is one area where the G-Class has progressed enormously over the decades. It’s still quite upright in terms of the dash design, but you’re confronted by twin 12.3-inch screens, supporting the Mercedes-Benz user interface. 

All very high-tech, but that’s balanced by an old-school grab-handle for the front passenger to latch onto during off-road work. 

The signature turbine-style air vents are located within squared-off panels, and in the limited Edition One you have a blue fleck running through carbon-fibre inserts on the centre console, door cards and that front grab handle. In the standard car it’s a (very attractive) walnut open-pore wood rather than carbon.

A luxurious interior for sure.

The LBX is a compact little SUV so if you’re after something to fit a family of four, look elsewhere. But if you don’t need the space, it’s a great city car.

Up front it’s easy to find the right driving position thanks to all of the adjustability of the seat and steering wheel.

Those sports seats are supportive and hug the body, but not too much as some of Lexus’ European rivals do. They’re also very comfortable - almost edging firm but never uncomfortable.

The Lexus multimedia system is functional and has an easy-to-navigate menu set-up, but lacks any pizzazz. Better graphics would help with engagement.

Storage wise, there’s a wireless charger slot at the bottom of the centre stack, a cupholder with a narrow slot for another device next to it, and a deep but narrow secure central storage bin with another cupholder.

You might not fit big bottles into the door bins as it’s pretty tight.

I wasn’t sure about Lexus’ one-touch interior and exterior door handles when they first rolled them out, but I now think it adds a classy point of difference to its rivals.

That second seating row is tight, especially for taller folk. I had just enough legroom (but plenty of toe room) sitting behind my 183cm (6'0") driving position, but I wouldn’t want to sit back there for a long road trip. Headroom, however, is ample. My noggin didn’t even scrape the headliner. You’d struggle to fit three adults back there but a couple of kids should be fine.

Amenities include a pair of USB-C ports and two map pockets, but the rear row lacks any adjustable air vents or a fold-down centre arm rest. And the bottle holders in the rear doors won’t fit much at all. 

The rear row folds 60/40 and if you need to haul lots of luggage or shopping, you’ll definitely need to lower that rear row because the boot is small.

Lexus says it can swallow 266 litres, which is tight. There’s no spare wheel of any kind, just a tyre repair kit.

For the record, the G63 is just over 4.6m long and a little more than 1.9m wide with a 2890mm wheelbase. So, not huge, but its close to 2.0m height is hard to ignore. 

In the front there’s lots of breathing space, and in terms of storage you have generous bins in the doors with plenty of room for big bottles. Then there’s a centre armrest, which doubles as the top of a deep storage box housing a USB-C port inside. 

A sliding roller cover in the centre console reveals two cupholders, another two USB-C sockets, a 12-volt outlet and a wireless charging pad. Add in a big glove box and you’ve got plenty of options in terms of storage, power and connectivity. 

In the back, sitting behind the driver’s seat set for my 183cm position I’ve got tons of foot and legroom and, no surprise, lots of headroom.

There’s a fair bit of sculpting in the rear seat, which is as nice as it is unusual (makers often avoid bolsters on the rear seat as it makes the backrest harder to fold flat). And in terms of three-abreast accommodation, a smaller adult will be okay in the centre spot for shorter journeys. Three up to mid-teenage kids will be swimming in it.

Then, for practicality you again have generous bins in the doors. And if you need even more capacity, fold down the centre armrest which houses two different size cupholders. 

In the rear of the centre console you’ve got two USB-Cs, a 12-volt power outlet, individual climate control and directional vents.

There are map rockets on the front seatbacks and more air vents in the B-pillar. So, when it comes to comfort, powering up devices and storing ‘things’ you’re well taken care of.

The side-opening tailgate door opens from right to left, which isn’t ideal when parallel parked on the left hand side of the road, but boot volume is over 600 litres (VDA) with all seats upright, expanding to nearly 2000 litres with the 60/40 split-folding rear seat lowered.

There are multiple tie-down hooks, a netted pocket, two lights, a 12-volt outlet as well as a ‘ski-port’ door and sliding cargo cover to enhance practicality and security.

As mentioned earlier, the full-size spare in the standard model, but the Design Box replaces it on the Edition One, although Mercedes-Benz says it’s aiming to make a spare available as an option later in the year.

The new Mercedes-Benz G580 is priced at $249,900 and a more highly-specified limited Edition One version comes in at $299,900, both before on-road costs.

That’s a price territory where the BMW X5 and X6 M Competition ($244,900 & $250,900) as well as the Range Rover Autobiography ($233,961) live. Not to mention competition from the G580’s still available and appreciably pricier twin-turbo V8 Mercedes-AMG G63 stablemate ($365,900).

As you’d expect, the standard features list is substantial and the highlights are Burmester 3D Surround Sound audio (with digital radio), leather upholstery, keyless entry and start, a multi-function steering wheel trimmed in Nappa leather, power front seats with memory function, heated and cooled cupholders, and wireless smartphone charging. 

There’s also dual 12.3-inch driver instrument and central media displays, ambient lighting and adaptive LED headlights as well as Android Auto and Apple CarPlay.

As well as cosmetic changes, covered shortly, the Edition One steps up to ‘Silver Pearl’ and black Nappa leather trim (with blue contrast stitching).

There’s also a range of optional packages bundling up everything from exterior body elements to interior trim and additional multimedia, the latter especially for back-seaters. 

The ‘Night Package’ ($4300) includes black exterior mirror housings, black running boards and wheels as well as darkened exterior lights and a radiator shell that can be illuminated for an impressive profile while driving.

A ‘Superior Line Interior Plus Package’ ($14,500) brings full Nappa leather upholstery, ‘Active Multicontour Seat Package Plus’ and grab handles in leather. Then a ‘Manufaktur Exterior Package’ ($4100) finishes the roof, bumpers and wheel arches in ‘Obsidian Black’. 

But the one that will score you maximum brownie points with the kids is the ‘Interior Comfort Package’ ($8500), featuring a rear seat entertainment system, including two integrated 11.6-inch touch displays.

Powering the LBX Morizo RR is an excellent 1.6-litre turbocharged three-cylinder petrol engine, which is the same unit found in the Toyota GR Corolla and Yaris hot hatches.

The Lexus loses some power and torque compared with those models so the outputs are 206kW and 390Nm. The Toyota cousins offer 221kW/400Nm each.

This engine is paired with an eight-speed torque converter automatic transmission and it has electrically controlled all-wheel drive with a Torsen limited-slip differential.

You can race from zero to 100km/h in just 5.2 seconds.

The G580 is powered by four permanently excited synchronous motors, each delivering around a CLA200’s worth of power and torque to each wheel for overall outputs in excess of 432kW/1164Nm.

Each motor has its own two-stage transmission and power electronics for almost infinite fine-tuning of the direction and amount of drive sent to individual wheels. Merc calls it ‘individual-wheel drive’.

While the hybrid versions of the LBX are known for their fuel efficiency, it’s less of a focus for the Morizo RR performance model.

It has an official combined (urban/extra-urban cycle) fuel figure of 9.2 litres per 100 kilometres, which is more than twice the figure of the hybrid.

CO2 emissions sit at 209g/km and the LBX has a 50-litre fuel tank. You will need to fill up on the expensive stuff though as the Morizo RR requires 98 RON fuel. Theoretical range between fills is around 540km.

Housed in a torsion-resistant casing and embedded low down in its ladder-frame chassis, the G580’s 116kWh two-tier, liquid-cooled lithium-ion battery pack delivers a WLTP-rated range of 473km, or 567km on the more lenient NEDC scale.

‘Eco Assistant’ and ‘Range Monitoring’ functions provide continuous information on battery status, energy consumption and estimated range.

Maximum system capacity is 400 volts which enables 200kW DC charging, meaning a 10 to 80 per cent fill in as little as 32 minutes. Maximum AC charging capacity is 11kW.

Claimed energy use is 23.1kWh/100km, and we saw an average of 28.6kWh across urban and highway running on the launch drive program.

Not exactly a ‘green’ EV choice, then, but it’s worth noting a one-year Chargefox subscription is included to off-set the car’s energy appetite.

I had high expectations for the LBX Morizo RR and I’m pleased to say they were met.

What a phenomenally capable little car.

Lexus is at pains to point out that its mechanical cousins - the Toyota GR Corolla and Yaris - are motorsport bred and therefore more raw and hardcore.

The premium brand knows it needs to be able to attract new buyers with a car like this, while also satisfying its loyal base.

Lexus did this by building a hot hatch (okay, it’s an SUV) that you can easily live with day to day.

I spent an enjoyable few hours behind the wheel of the Morizo RR on a stunning Autumn day in Victoria’s Yarra Ranges driving on some incredible roads. The twists, bends, undulations and more showcased how tight this car is.

First up that engine is an absolute gem, and I don’t miss the extra kilowatts found in the Toyota models. There’s very little turbo lag and the LBX picks up pace quickly but in a focused, fun manner.

The engine note is also a delight to behold, especially when you push it hard. Although on coarse chip roads a fair bit of road noise creeps in, to the point that it's boomy.

The transmission is a perfect pairing for the engine, too, offering slick shifts without holding gears unnecessarily. I didn’t miss the manual box found in the Toyotas, either. But the paddle shifters and a true manual mode (it won’t shift unless you flick the paddle) adds to the experience.

The brakes are strong but not too pinchy and the steering is as sharp as you’d hope, while offering just enough weight. 

Then there’s the grip. The all-wheel drive system “automatically distributes the front-rear torque according to road conditions and grip”, according to Toyota.

That AWD grip always inspires confidence during dynamic driving in a car like this and the LBX sticks to the tarmac like nobody's business. Despite some damp sections of road higher up the ranges, no slip was detected. It feels glued to the road.

If that’s not enough, the Lexus surprises with its compliant and even comfortable ride quality. Many hot hatches (or hot SUVs) have a firm ride due to a chassis set-up geared to performance driving. 

Somehow Lexus has ensured the damping settings shield the occupants from the worst bumps. Only deep potholes make their presence felt.

And that’s the beauty of this car. It feels so beautifully engineered, with a clear focus on performance, but it’s not a brutal experience. You never feel like you could easily lose control in this thing. You can punt it into a tight bend and feel confident it will stay the course.

So, with 432kW and around 1160Nm, even though the G580 weighs in at around three tonnes, you’re talking 0-100 km/h in 4.7 seconds. And this car gets up and goes… like a beast.

What you don’t get is that traditional Merc-AMG G63 V8 rumble, because, of course, no engine. 

But you do get what Mercedes calls ‘G-Roar’, essentially a sound bar at the front of the car also using the audio system inside to give it what is not exactly an engine noise but some sense of the car progressing. And you can turn it off for completely silent running.

‘Electric Dynamic Select’ changes the parameters of the motors, transmission, suspension, ESP and steering as required. On-road that means ‘Comfort’, ‘Sport’ and ‘Individual’ modes, with off-road comprising ‘Trail’ and ‘Rock’. In the Comfort setting drive flows primarily to one axle for optimum energy efficiency.

Suspension is by double wishbones at the front and a De Dion-style live (rigid) axle at the rear. You’ve got the same adaptive-type set-up as per other G-Class models, so ‘Comfort’ and ‘Sport’ modes and of the many traditional G-Class traits this car exhibits, ride quality is one of them.

Even in Comfort you’ll find even little bumps and thumps making their way up into the seat of the pants and the cabin. It is after all a body-on-frame, ladder-chassis type vehicle and that’s not unusual.  

In terms of steering, it’s accurate and road feel is good. You’ve got 275-wide Falken Azenis FK520 tyres that are more on- than off-road focused. The car feels stable and nicely planted on the road.

The physical brakes are by ventilated discs front and rear, and the big rotors are the same size (353mm) all around. They work nicely and feel like a conventional set-up.

Regenerative braking kicks in as soon as you lift off the accelerator pedal. The powertrain is harvesting energy as the car decelerates and there are four levels you can adjust with the steering wheel paddles up to a quite aggressive level - not quite, but close to a single-pedal set-up.

Off-road, the G580’s ‘G-Steering’ system allows the wheels to turn at different speeds to induce slight ‘drift-like’ oversteer and tighten the turning circle. It works beautifully and the car’s fording depth is 850mm, a full 150mm more than internal-combustion G-Class models.

A three-speed off-road crawl function is adjustable to speeds as low as 2.0km/h, and the car is claimed to remain stable on sideways slopes up to 35 degrees. 

Torque vectoring is used to create ‘virtual diff locks’ and there’s a ‘low-range’ setting. Switch to the ‘Offroad Cockpit’ and data including gradient, lateral inclination, compass readings, tyre pressures and the selected G-Mode appear.

A ‘Transparent Bonnet’ function creates a virtual view of what’s approaching and passing under the front wheels to help the driver pick their way through steep ascents or declines.

For the record, the G580’s approach angle is 32 degrees, departure is 30.7, breakover is 20.3 and ground-clearance is 250mm.

And of course, with the wheels independently powered, the G580’s signature move is what Mercedes-Benz calls a ‘G-Turn’ but the rest of the world calls a tank turn.

If you encounter an obstacle that makes forward progress impossible, the system spins the left- and right-hand wheels in opposite directions so this brute can turn on the spot like an M1 Abrams. You can’t help but crack up laughing when executing this extreme party trick!

In terms of miscellaneous observations around ergonomics and the car in general, it has a 13.6-metre conventional turning circle. So if you’re not using the G Turn function in the car park be ready for a sizeable turning arc.

Also, those aero tweaks here and there seem to have had an effect. Wind noise, especially for such an upright, squared-off design is surprisingly modest. And overall, from a build point of view, this car feels as though it’s been carved from a solid piece of metal. In every aspect it presents as a quality item.

Although the Mercedes-AMG G63 carries a maximum five-star ANCAP safety assessment from 2018, the pure-electric G580 is unrated. But crash avoidance tech includes active cruise control, ‘Active Steering Assist’, high-speed AEB, traffic sign recognition, lane-keeping assist, blind-spot monitoring, driver fatigue monitoring as well as a 360-degree camera view and ‘Active Parking Assist’.

And if a crash is unavoidable, there are no fewer than 11 airbags on-board, including driver and front passenger front and side, rear side, full-length curtains, driver and passenger knee and a front centre bag.

There are three top-tether points for child seats across the second row, with ISOFIX anchors on the two outer positions.

Lexus covers the LBX Morizo RR with its five-year, unlimited kilometre warranty and capped-price servicing for five years at a cost of $695 a service.

The schedule for servicing is tight at every six months or 10,000km, whichever occurs first, so you’ll be at the dealership a bit with this one. These are the same servicing terms as the GR Corolla and Yaris.

Lexus’s 'Encore' owner benefits program includes some cool stuff, too, like a valet parking service at certain venues, and you can even swap your Lexus for a different model for a set amount of time with the On Demand service.

Lexus Encore also offers exclusive access to events and venues, as well as special offers at hotels and restaurants.

The G580 is covered by Mercedes-Benz Australia’s five-year/unlimited-km warranty, which remains the standard offering in the premium part of the market and an eight-year/160,000km drive battery warranty.

Service intervals are every 12 months or 20,000km with service plan pricing available over three ($2645), four ($3980) and five ($4670) years. In approximate terms, each workshop visit will cost ‘around’ $900. Not exactly cheap, especially for an EV, but this is no ordinary electric vehicle.
