Lexus LM vs Mercedes-Benz GLA-Class

What's the difference?

The Lexus LM is going to be a niche model. This was not designed to appeal to people that may have bought a Toyota Tarago back in the day, or even a Kia Carnival now.

It has a specific purpose for ferrying people around in absolute comfort and at that, it succeeds in a big way.

It’s just a bonus that it’s great to drive.

Welcome to the automotive equivalent of a business class airline suite.

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

With Mercedes-Benz’s vast number of SUVs, there is room for an urban luxury crossover niche, and the GLA delivers in spades.

Indeed, in 250 4Matic guise, it is that rare thing – a high-riding hatch with dynamics to shame most dedicated pocket-rockets. It really is a hoot if you find the right road, regardless of weather conditions. The Benz has towering talent.

However, even without desirable options like adaptive dampers and a full suite of driver-assist safety technology, the GLA is expensive, does not quite carry off the price tag from an interior quality point of view, and struggles to maintain the degree of comfort and refinement expected from a Mercedes – with or without the $3K necessary to score adaptive dampers.

Still, especially because of the way the GLA looks, goes, stops and steers, if you can afford it, you’ll be rewarded. There’s never been a more rounded GLA.

Look, people movers are not considered the sexiest of automotive body styles, but that’s changing.

The Kia Carnival and Hyundai Staria are examples of good MPV design.

And the Lexus LM steps it up again. 

It is based on Toyota’s TNGA-K architecture that underpins a bunch of Toyota and Lexus models, including the Lexus RX, and it measures a whopping 5.1 metres long and has a three-metre wheelbase.

It shares its underpinnings with the latest generation Japanese-market Toyota Alphard, which is a cult hit in Australia among the grey import set.

The front-end design is bold, with the latest take on Lexus’ big ‘spindle grille’, pinched slimline headlights and a stubby nose. 

I am a big fan of this design. It is far more than a box on wheels and it has quite a bit of presence. 

The interior design up front is modern Lexus, with a few familiar Toyota touches, and while it’s not exactly minimal, it’s still visually appealing.

Looking like a mini-me GLC, today's GLA trades some of its predecessor’s edgier design elements like the slammed roof and exaggerated broad-shouldered stance for a more amorphous if elegant appearance. Even with the cliché plastic cladding around the squared-off wheel arches, it’s still a looker.

The net result is arguably the most attractive of all the MFA2 A-Class offshoots. It sits well within the Mercedes hierarchy of SUVs, bringing a swoopy coupe-like silhouette compared to the ultra-upright GLB.

Along with being 30mm wider, it’s also visibly taller than before, with a handy 213mm of ground clearance compared to just 157mm last time around. And the wheelbase has been stretched to the benefit of rear-passenger room – a bugbear of the old GLA. That's progress.

While most of the fun happens in the second row of the Lexus LM, there is a lot to like in the front compartment.

The dash is dominated by a large touchscreen that houses Lexus’ latest multimedia setup. The logical menu and uncomplicated sub-menus ensure this is an easy system to navigate. Speaking of, the in-built sat-nav is one of the better systems I have experienced. 

Comfort isn’t just the domain of the second row - the driver’s seat is very supportive and comfortable, with power adjustment.

There’s plenty of glass including a smaller front quarter window that helps eliminate front blind spots, so forward visibility is exceptional. Rearward visibility is aided by the digital rear-view mirror that is designed to ensure privacy for second and third-row occupants. You don’t want the chauffeur spying on you while you’re sleeping, do you?

The other big tick for me is the driving position. Other people movers, namely the Hyundai Staria and Mercedes-Benz EQV, have very low window lines and it leaves you with a feeling of sitting on the car, rather than in it. I am sure it helps with extra light and it probably makes it easier for kids to see out of, but from a driving perspective, I find it a little disconcerting.

But the LM has flipped that. The front compartment is designed in such a way that it feels like a cockpit that you’re ensconced in. This helps the driver feel more connected with the car, and in the LM it feels like you’re sitting in the driver’s seat of a sporty sedan, not a five-metre bus. Very well done, Lexus.

And now to the main event - the second row.

Where to begin. Let’s start with space. Because there is so much of it. Unsurprisingly given the seating layout, there is an unending amount of head, leg, knee, bum, shoulder and whatever-else room. I can’t imagine anyone complaining about space back there.

Also, getting in and out is a breeze thanks to the sliding power doors on both sides. These can be opened from the front seat, and via several buttons in the rear.

Those captain’s seats are plush. Not quite Benz S-Class plush, but still.

They are adjustable six ways - power adjustable, of course - and they’re heated and ventilated. They recline almost flat, too, if you need a nap on the way to the country estate. And while you do that you can look up through the split sunroof, or close the shade a number of ways.

Is there a massage function? Of course there is a massage function. And it’s not bad. You can choose two settings - weak and firm.

Adding to the feeling of a business class airline seat, there is a fold-out table in the armrest, although it’s a smallish one. And there is dual-zone climate control in the rear.

There is a roof-mounted control panel for things like climate, sunshades and sunroof blinds, but much of this can also be controlled by the Apple iPhone-like devices clipped into both rear seats. These are closer to the seats, so it is easier to access than the roof.

Another function in the device is the Climate Concierge that features different modes - Dream, Relax, Focus, Energise. Depending on which one you choose, it alters the seat settings, massage, climate and lights to suit.

I love the massively wide side windows that are tinted (or privacy glass), too.

Other amenities include map pockets, knee and roof-mounted air vents and a 14.0-inch display screen that retracts from the roof and connects to an HDMI cable, allowing you to watch whatever you want.

The third row is not as appealing as the second. It is technically a three-person row, but the width and the fact that it has a sizeable gap in the centre suggests that this is best thought of as a six-seater van.

The seats are not as plush of course, so you might not want to spend too much time in that row unless you are a small child. But you do get USB-C ports, cupholders, air vents, lights, sunglasses holder, power side shades and grab handles.

Getting in and out of the third row can take a while. It’s all power adjustable, so you don’t have to lift anything heavy - but it takes a while for the second row seats to move forward and up.

With all seats in place the cargo space is limited. In fact, it’s just 110 litres.

That’s similar to what you get in a seven-seat SUV. But it did fit all our overnight luggage easily.

Drop the rear row and that expands to a maximum of 1191 litres in the 350h or 752 litres in the 500h.

All grades have a space-saver spare wheel.

Compared to before, the 2021 GLA is some 122mm taller, so ushers in a higher hip point for loftier seating – reducing that jumped-up hatch feel. Headroom improves obviously, as does rear legroom, a corollary of a 30mm wheelbase stretch (to 2729mm).

Wide apertures also make entry into and out of the German-built GLA child's play, though the solid heft of their doors is serious business at this end of the segment, very satisfyingly Teutonic and totally on-brand. This is something you won’t enjoy in a Subaru XV.

Then you s-c-r-a-p-e the underside of the front doors on the pavement literally every time you swing it to get out, and wonder whether Mercedes engineers have ever been to Australia. This fail drove us spare. Heaven help the GLAs in towns and cities with bluestone sidewalks. Maybe all that extra AMG packaging is the culprit.

Still, most of the other basics are spot-on and can’t really be faulted; cosy yet spacious for four adults – especially up front, ample vision, an excellent driving position aided by heaps of seat and steering wheel adjustability, cosseting front sports buckets that you just sink into, torrents of ventilation from those delectable turbine vents and stacks of storage. Collectively they make the GLA a welcoming, opulent place to travel in. Only the hapless fifth occupant squished between the outboard rear-seat passengers might think otherwise. But nobody buys this Benz for carting people around. That's the GLB's job.

Several years ago, Daimler poached a senior Audi designer and since then Mercedes’ dashboards have morphed into a multi-coloured multimedia diorama of touchscreen technology that threatens to completely take over the universe. Choose the right combination of colours and lighting and it's like your very own White Night on wheels. Starting with 2018’s A-Class, the striking, spangly MBUX system that underpins all this has come to be widely admired and imitated. For aesthetics anyway, with its vivid hues, panoramic displays and simple, tiled applications, it’s been a real trip.

Anyway, back to reality. From a tactility and functionality point of view, there’s still work to be done.

Access to the multimedia (including our GLA's banging optional audio system) and car settings areas is possible via a mildly fiddly finger-pad arrangement down forward in the centre console, or smaller yet much more annoying thumb sensor tabs on the wheel spokes. These are not easy to modulate on the move. Additionally, their menus can be confusing to navigate through and sometimes counterintuitive in operation. Mercedes obviously realises this as a quick-guide pamphlet is provided on old-fashioned cardboard paper. How quaint.

Eventually all areas can be mastered over time, but the functionality is complicated and may overwhelm the not-so-tech savvy. Additionally, the ‘Hey, Mercedes!’ voice control is impressive for getting MBUX to perform basic multimedia and vehicle settings-related changes, but it too-often erratic, unreliable and ultimately frustrating for more complicated commands. Perhaps elocution lessons on behalf of the operator may help.

But not as much as the profound disappointment we endure from the cheapness of some of the materials, the wincing cellophane-like sounds when pressing on some of the surfaces such as the door cards, or that emanate after a particularly bumpy section of bad roads. Sheeny reflections and hard textures in a car optioned with extras that total up to nearly $82,500 just don’t cut it.  

At least in this latest-gen GLA, the rear seat area seems much improved over the previous models, with more space, comfy and supportive seating (remember ours featured the $607 sliding function that ought to be standard) and a reclining backrest. All amenities are present, with deep pockets, fresh air from twin vent outlets, reading lights and thoughtfully placed armrests – but, again, the latter’s extendable cupholders feel brittle and cheap.

Further back, the 435-litre cargo area is sufficiently sized and practical for smaller family use (at last), aided by a 40/20/40 backrest fold and that slide-able cushion to extend capacity further. There is no spare wheel, but a tyre inflation kit is fitted in lieu.

Overall, then, better than before, with that fundamental rock-solid heft, luxurious aura and alluring premium-car aroma. The dazzling MBUX screen-related visuals, too, are endlessly entertaining to explore when the vehicle is not moving, but the GLA’s cabin is still not quite up to Mercedes’ reputation for exacting over-engineered excellence.

Or even to the standards of some mainstream alternatives.

The latest GLA’s evolved dimensions is presumably to put some space between it and its GLB 5+2-seater SUV fraternal twin, giving Mercedes-Benz blanket SUV market coverage. From GL (for Geländewagen, or off-road vehicle) A, B, C, E and S (as well as the G-wagen icon that started it all back in '79), there’s a premium option for everybody… if not every budget.  

In the GLA’s case, the entry-level 200 front-driver starts from $55,100 (before on-road costs); moving up to the $66,500 250 4Matic, and then to two performance powerhouses – the AMG 35 4Matic and supernaturally fast AMG 45 S 4Matic+ flagship, from $82,935 and $107,035 respectively.

Even the base GLA 200 includes new and improved autonomous emergency braking (AEB) among other safety-related technologies, as well as the brand’s glamorous MBUX multimedia system with wireless Apple CarPlay/Android Auto, digital radio, satellite navigation, reverse camera, climate control, wireless phone charging, powered tailgate, automatic parking, auto high beam, rain-sensing wipers and 19-inch alloys.

All the extra techy stuff doesn’t come for free though – prices jump almost $10,000 over the less-powerful previous-generation GLA 180 that the 200 replaces – though we expect the former badge to return in time.

In contrast, the GLA 250 4Matic is ‘only’ $3500 more expensive than its predecessor, gaining a terrific 2.0-litre four-cylinder turbo instead of a Renault-Nissan-sourced 1.3-litre turbo, all-wheel drive (with an Off-Road Engineering Package that gives the car some very light off-road capability), and other niceties such as heated electric front seats with memory function, a panoramic sunroof, more direct steering and lowered suspension (for a sportier drive).

Note that adaptive cruise control costs extra – a curious oversight at this price point. It’s part of a $1531 optional Driving Assistance Package, which also includes Active Lane Change Assist, extended semi-autonomous driver assistance in traffic jams (meaning full stop/go capability) and route-based speed adaptation. Do it.

Our test car had it, along with a $915 Vision Package (includes fancier adaptive headlights and a 360-degree camera), $1915 Sports Package (with AMG styling upgrades inside and out, perforated disc brakes, privacy glass, shift paddles and lowered ‘Comfort Suspension’), a Night Package (less brightwork, more black finishes) and sports direct-steering with corresponding wheel), $1531 20-inch AMG Black alloys, a $1915 Communications Package with upgraded audio and head-up display among a litany of other gear, $2838 AMG Exclusive Package with adaptive dampers, cooled as well as heated front seats, an ‘Energising Comfort’ ambience-enhancing 'experience' and special leather upholstery, $1531 Patagonia Red metallic paint and $607 rear-seat fore/aft adjustment. Total cost after the added luxury car tax: $82,446. Gulp.

Not cheap in anybody’s language. Nor, for that matter, are the GLA’s rivals, which owe their existence to the original’s spectacular sales trajectory and the trail that this blazed last decade.

Lexus’ loaded UX 250h hybrid AWD and Audi Q3 Sportback 40TFSI quattro slip slightly below the standard GLA 250 for both pricing and power, while the BMW X2 M35i and its Mini Countryman JCW cousin, along with Jaguar’s E-Pace E250, also offer in-the-same ballpark pricing but quite a bit more space as well as pace.

It’s also worth noting that Volvo’s XC40 T5 AWD conspicuously undercuts all from just $57,000, though now we’re talking about putting square pegs into round holes. Speaking of which…

There are two hybrid powertrains available. Coming next year, the LM500h combines a 2.4-litre turbocharged petrol engine and a hybrid setup, making for power and torque of 202kW and 460Nm respectively. It is all-wheel drive and is paired with a six-speed automatic transmission.

The LM350h comes with a 2.5-litre naturally aspirated petrol engine and a parallel hybrid system, offering up a total system output of 140kW and 239Nm. The 350h comes in front or all-wheel-drive guise and uses a continuously variable transmission (CVT).

Mounted transversely, Mercedes’ M260 1991cc 2.0-litre four-cylinder petrol engine features a twin-cam, 16-valve design, a twin-scroll turbocharger and variable-valve timing, to help deliver 165kW of power at 5500rpm and 350Nm of torque at a low 1800rpm. With an impressive 97.2kW per tonne, it can hit 100km/h in 6.7 seconds, on the way to a 240km/h top speed.

All four wheels are driven by an eight-speed dual-clutch transmission (DCT), though most of the torque at lower speeds or during reduced throttle loads is delivered to the front wheels until extra traction is required out back. The gearbox is one of the very best of its type we’ve experienced – seamless, strong and largely lag-free.

As you’d hope with an all-hybrid line-up, the LM excels when it comes to combined cycle fuel efficiency. The 350h FWD sips just 5.5 litres per 100 kilometres, while the AWD version is 5.6L/100km. The 500h is a little thirstier at 6.6L. 

Our drive was so brief we did not get to record an on-test fuel figure.

The theoretical range of the LM, considering the 60-litre fuel tank and 5.5L/100km (350h) and 6.6L/100km (500h) fuel consumption figures is about 1000km.

Weighing in at 1668kg (kerb), and with a bluff nose and high ground clearance also not helping, we didn’t expect great fuel economy, particularly given how hard and fast the GLA 250’s performance bandwidth is. It’s tempting to just blast your way from point A to point B.

However, at the pump we averaged 9.8 litres per 100km, which isn’t too bad at all considering the available muscle. The official figure is 7.5L/100km, for a carbon dioxide emissions rating of 170 grams per kilometre. With a 51-litre fuel tank, the theoretical range is around 680km.

Note that the GLA 250 requires 95 RON premium unleaded petrol as a minimum.

As mentioned earlier, I spent much more time in the second row as a passenger than I did behind the wheel of the LM350h. But it was enough time to capture some initial high-level drive impressions.

But let’s start in the rear. The ride in the second row is comfortable - as you’d hope. Our trek from Melbourne’s inner north down to the Mornington Peninsula included a lot of freeway, which was smooth. The only thing that disturbed the peace was a chunky bridge join that caused a bit of a thump. But we were hardly disturbed. 

Back in the driver’s seat, there’s a lot to like about how the LM350h drives. First of all, it feels smaller on the road than its ample dimensions would otherwise suggest. It even feels relatively light on the road. 

After the LM, I drove a Mercedes-Benz EQE SUV that has a similar kerb weight (the Lexus is about 2.4 tonnes), and the LM felt lighter.  

The hybrid powertrain is responsive enough, offering decent acceleration from a standing start. The more potent 500h will of course be quicker.

The transition from electric to petrol propulsion is pretty smooth in Lexus (and Toyota) models these days, and the additional noise-deadening materials in the LM ensure it’s subtle.

The 2.5-litre petrol engine is really only noticeable when accelerating hard, and the CVT a slight drone, but it’s in no way unpleasant. 

Otherwise it’s a superbly refined and quiet cabin on all but the absolute worst road surfaces. Whisper quiet power windows adds to that feeling of luxurious refinement.

Given the brief time behind the wheel, we didn’t get to test the handling capability of the LM, so that might have to wait for a review in the New Year. 

The steering is heavily weighted and doesn’t feel overly responsive, but it’s perfectly suited to this sort of vehicle.

That supple ride we experienced in the rear was also evident behind the wheel.

This was especially impressive on a couple of pock-marked peninsular back roads. The ride is also much more compliant than the Mercedes-Benz EQV I tested early in 2023.

A soaring 2.0-litre turbo engine application, this is a slick, stirring and robust performer that can also do efficiency as effortlessly as launch the GLA 250 4Matic towards the horizon. Let’s not mince our words. This is a fast and fiery mover.

Three drive modes – Eco, Comfort and Sport – provide a wide spectrum of acceleration and throttle responses, and all deliver precisely what you’d expect. Eco’s fine for pottering around town smoothly and serenely; Sport morphs into a searing and seamless speed demon; and the default Comfort sits somewhere in the middle as the best of both worlds. There really is no faulting Mercedes’ M260 masterpiece.

The DCT also happens to be one of the better dual clutch autos, avoiding the lag and clunkiness pitfalls usually associated with this sort of gearbox. It’s even comparatively smooth off the line on hills. Ours came with the optional handy set of manual-mode paddle shifters, adding a welcome level of interactivity autos tend to overlook. Too bad Mercedes persists with that fiddly column lever that is forever prone to knocking the car out of drive. Even after 15 years, it's still so annoying.

What all this means for the urban driver is strong acceleration for flitting in and out of traffic gaps, as well as incredibly instantaneous point-to-point responses for commanding manoeuvrability, thanks to ultra-eager steering and assisted by outstanding brakes.

With struts up front and a multi-link rear end as standard, the GLA 250’s chassis, too, is a transformative for what is essentially a high-riding hatchback – but only if your pockets are deep enough.

Fitted with that near-$3K AMG Exclusive Package that includes adaptive dampers, our Benz displayed a definite hot-hatch attitude that really would make it the darling of Golf GTI owners who’ve outgrown their rides but not their girl/boyracer desires. Superb handling and hunkered-down roadholding really do make this the driver’s premium compact crossover. You can pretty much point and shoot this Merc as you might a Golf R, and likewise in most weather conditions thanks to all that reassuring tenacious grip.

Plus, if you’re put off by the hard ride in Sport, the Individual mode allows the driver to engage the soft damper mode while the engine and steering retain the hardcore settings. It’s a win-win situation – as long as you can stretch to that AMG Exclusive pack. We strongly recommend it, given the balance between ultimate high-speed control and comfort.

However, while this is all good news for rural and country folk seeking hot crossover fun, back around town, poor urban road conditions can reveal a flaw in the chassis’ ability to properly smother bumps and ruts. It’s the small frequency stuff that seems to transmit through, never really settling down.

The result is a jittery ride, that may somewhat undermine the GLA’s upmarket sheen. There’s also a fair degree of road noise coming through. Perhaps sticking with the 19-inch alloys instead of those lovely 20-inch rims is the solution here.

Mercedes-Benz is a long and proud pioneer in passenger-vehicle safety, and the GLA is no exception… except that for the full suite of safety assistance you need to fork out more in the GLA 250.

The standard roll-call of advanced driving assist systems includes nine airbags (front, pelvis side and window bags for driver and front passenger, side airbags for rear occupants and a knee airbag for the driver), AEB with pedestrian and cyclist detection, and blind-spot monitoring with an exit warning that alerts the driver of approaching cyclists or vehicles if the door begins to open into their path.

The AEB system has a working range of between 7km/h and 200km/h.

Active Lane Keep Assist, an active bonnet that raises to reduce head injury, Cross Wind Assist, Pre-Safe accident anticipatory systems and traffic sign recognition tech are also present.

Additionally, front and second-row seatbelt reminders are fitted, as well as two rear-seat sited ISOFIX child-seat anchorage points and a trio of child-seat tether points behind the backrest.

But you’ll need to fork out another $1531 for the optional Driving Assistance Package, which includes adaptive cruise control with full-stop/go, Active Lane Change Assist, extended semi-autonomous driver assistance in traffic jams, and route-based speed adaptation.

At the time of publishing, the H247-series GLA’s crash test rating results had not been published, but the closely-related GLB tested in 2020 managed a full five stars.

When you buy a Lexus, you get a bit more than a car. The brand has a customer loyalty program - Lexus Encore - and depending on what model you buy, you are eligible for some pretty cool discounts, bonuses and experiences. 

There are three tiers, depending on your model. UX, NX, RX and ES fall under regular Encore, and electric models the RZ and UX300e sit beneath Electrified Benefits. But the LM, as well as the LS, LC and LX are under Encore Platinum - the top tier. 

That means access to the ‘On Demand’ program that allows access to another Lexus model for a few days or longer. So if you own an LC Convertible but need an RX for a few days to ferry people around, that’s all free. There’s valet parking service loans and more.

It also includes upgrades at Lexus partners. Our launch took us to Jackalope Hotel on the Mornington Peninsula, which is a Lexus partner, and you can get a bunch of extras here as a Lexus owner that other guests won’t get.

In terms of other ownership details, the LM is covered by a five-year, unlimited-kilometre warranty, and the servicing schedule is every 12 months or 15,000km.

Lexus is yet to announce the capped-price servicing details for LM, but it is expected to cover five years, and should be in the vicinity of approximately $700 per service.

Unlike many luxury brands that persist with a sub-par three-year warranty, Mercedes-Benz offers a five-year/unlimited kilometre warranty.

Intervals are every year or 25,000km, with a capped price service plan starting at $550 for the first year, $750 for the second year and $1250 for the third year, totalling $2550. Alternatively, buyers can also choose a Service Plan, starting at $2050 for the first three years (saving $500 from the normal capped-price service plan), $2950 for four years and $3500 for five years.
