GWM Tank 500 vs Lexus ES300H

What's the difference?

The GWM Tank 500 Ultra PHEV is an impressive five-seat 4WD wagon. It’s reasonably nice to drive, it’s comfortable and it’s a capable 4WD. These vehicles keep improving and are increasingly stacked with characteristics to like.

There are still glaring range-specific issues with some of its driver-assist tech and its plug-in hybrid set-up doesn’t offer the fuel economy you’d hope for. At least not under real-world testing conditions. But the Tank 500 is packed with features and represents decent value-for-money when cross-shopped against the likes of its stablemate the regular hybrid, or the Prado and Everest.

There’s no denying the Sport Luxury is imposing, spacious, plush, chock-full of kit, efficient, speedy and pleasingly relaxing up to a point.

But its interior is also dated and true ride comfort can be elusive beyond smooth roads for this top-of-the-line version to make the grade as a proper luxury sedan.  

The ES 300h feels more like an aspirational Toyota than a Lexus for the (wealthier) masses, especially after recent triumphs like the latest NX and RX SUVs. The Camry DNA is difficult to disguise, as the amused strangers who sat in our test car uninvited thinking it was their Camry highlights.

Sure, the hybrid is no Chevy V8, but in many other ways, the Sport Luxury seems like the modern successor to the Holden Caprice experience.

In terms of dimensions, the Tank 500 Hi4-T PHEV is 5078mm long (with a 2850mm wheelbase), 1934mm wide and 1905mm high. It has a listed kerb weight of 2820kg, so it’s not an insubstantial vehicle.

There are plenty of old-school 4WD design cues in the Tank 500’s appearance. It’s mostly chunky and straight up and down, with some softer curves here and there as concessions to contemporary styling.

It's clear to see where the GWM Tank 500 takes its cues from – most of the current crop of popular 4WD wagons, such as the Toyota LandCruiser 300 Series.

The Tank 500 is a large vehicle straddling that line between large and extra-large 4WD wagons. It is longer than any 300 Series, but it’s narrower and shorter.

It has a sunroof, roof rails, electric side steps (that extend when doors are opened and retract when doors are shut) and 18-inch alloy wheels.

The interior is well laid-out and functional with some understated class to it. There are soft-touch surfaces and genuine Nappa leather seating throughout.

Historically, cars like the ES appeal to an older and more conservative demographic, who value imposing, conspicuously-expensive looking sedans offering the luxury of space. This is the Cadillac model and our Lexus embodies it.

Which is why hire company operators snap such vehicles up. Great for airport-hotel-airport runs.

But it’s weird, given how much of Lexus’ design language is in the ES’ elaborate nose and tail treatments, how generically Toyota this looks. Certainly, our test car’s 'Sonic Quartz' white paint job does not help.

Just to reinforce this perception, two strangers were fully sat inside our unlocked test Lexus before they realised it wasn't their actual car parked nearby – a white Camry of course.

How they laughed. But if I had paid over $80K for my ES, I certainly wouldn't be amused.

This Tank 500 has five seats because the two at the very rear have been removed to accommodate the hybrid battery.

The front seats are Nappa leather, power-adjustable (eight-way for the driver, six-way for the front passenger), as well as being ventilated with massage and memory functions.

The three-position second row – set up in a 60/40 split-folding configuration – breaks the usual 4WD wagon second-row seat tradition of being fine but not fantastic. The second-row set-up in this Tank is a first-class-cabin-style back seat with a flip-down control console (which includes air-con controls) instead of a basic centre armrest.

As mentioned there is no third row in this Tank 500 because of its underfloor battery.

Up front, the 14.6-inch multimedia screen (with wireless Apple CarPlay and Android Auto) dominates the dash. It's generally easy enough to use, although I had difficulty getting my iPhone hooked up to the system and the cabin set-up remains clunky and counter-intuitive in its operation.

The cabin has wireless charging, front and rear USB ports, as well as 12V and 220V power outlets.

The second row folds away to expand the rear storage capacity. Cargo volume is a listed 640 litres when all seats are in use and 1400 litres when the second row is stowed away.

The rear cargo area has tie-down points and a cargo slide cover.

The ES 300h may look like a gussied-up Camry on the outside, but there’s very little evidence of the Toyota inside the stretched cabin, with Lexus-specific seating, trim and dashboard.

However, if you’re familiar with the latest LS, NX or RX models, much of what you see is now dated, previous-gen tech, and that’s an issue in some key ways.

Let’s start with the SL positives, though.

Quiet and free from rattles, the interior is defined by its first-class fit and finish, and then closely followed by the vast length inside, with ample room up front to stretch out and relax in. The ES’ substantial width adds to the sense of spaciousness.

Ventilation is excellent, exemplary even, with strong and effective climate control all around the car. Great for very hot days.

The front seats provide practically infinite adjustment in most directions, and include a handy thigh-support extender that – like everything else inside – moves electrically.

Comfy and supportive, they do a fine job. Effective heated and vented cushions and backrests are further bonuses.

But let's call out the hard front headrests. They feel cheap. And the ES’ age now shows in other, eyebrow-raising ways for an $80K-plus machine.

The dash is a messy mix of now-dated Lexus styling cues – from the ugly asymmetrical centre console to the single circular instrumentation dial for speed and tachometer.

The original IS 200's analogue watch face theme was cool in '99. Today's iteration looks basic.

Storage seems poorly judged given the vastness of this sedan, provided for by cavities in the sub-sized centre armrest, glove box and door bins. Note that the latter cannot hold bottles.

Then, there’s the ill-conceived touchpad that requires brain-surgery precision when fingered to navigate the main display screen when driving (though now it's also a touchscreen, and not before time); after years of various iterations of this, it remains alien and confounding in the extreme to operate. Rest assured, it's been banished in newer-gen Lexuses.

Also annoying is the infernal ‘please obey all traffic regulations’ voice warning, just like you find in a Yaris; the limited and easily-flummoxed voice-control tech and the dated and low-fi graphics for the needlessly complicated sat-nav system.

We relied on CarPlay because the in-built item endlessly let us down. Chuck them all out.

However, there are upsides to a dated interior, because even though this is a confusing and at-times intimidating button-fest, it’s still preferable to the today's everything-behind-a-touchscreen mania.

Give us physical switches and buttons every time, like the ES. Yes, the Lexus also has them replicated within the central display, but the point is, the driver has a choice.

You shouldn't be shocked to learn that the Sports Luxury impresses most as a sumptuously comfortable back-seat experience.

Rear access is easy, the passengers can adjust the front seat, climate control and audio systems via handily-sited switches (meaning they're replicated thrice in some instances).

Limo luxury amenities include individually-reclinable and heated outboard seats that are downright sumptuous, blinds for all glass (electric for the rear window), a lined centre bin, face-level air vents, two USB ports, a 12V outlet, generously-sized elbow rests on the doors, overhead lighting and door pockets are also included.

This is tailored as an airport/hotel shuttle and very comfortable doing so.

No folding backrest, though, meaning the boot – though not small at 454 litres – lacks the load-through facilities now common in most other sedans, including the Camry.

Under the flat floor is a space-saver spare with the words ‘SPACE MISER MKIII’ emblazoned across it. Classy.

In summary, the ES’ interior is one of two parts – comfortable but dated up front, invitingly lush out back. Perfect for its intended station in life then.

The second-oldest Lexus nameplate after the LS flagship, Australia skipped the fifth-gen version from 2006 to 2012 altogether because it was ousted by the smaller, sportier and more-popular IS series.

However, the latter’s 2021 demise saw the situation flipped, with the ES retaking the mantle as the affordable Lexus sedan torchbearer, while also belatedly replacing the larger GS.

This all coincided more-or-less with a facelift later that year, which brought revised front-end styling, uprated safety, updated multimedia, extra kit and a beefier body, among other changes.

Plus, a (slightly) cheaper non-hybrid ES version returned, dubbed 250. Starting from $61,620 (all prices are before on-road costs), it uses the Camry’s 2.5-litre four-cylinder atmo petrol engine.

However, the 300h hybrid from about $2K more is the better seller, with its electric motor and battery pack assistance. Our test SL flagship kicks off from $78,180, and heaves with standard equipment.

On the safety front, the usual array of driver-assist tech is present, starting with Lexus’ pre-collision system that includes Autonomous Emergency Braking (AEB), blind-spot monitor, adaptive cruise control and lane-keep warning/assist. See the safety section for more.

The biggest change inside is the now-touchscreen-enabled 12.3-inch display, boasting a 360-degree view camera, Apple CarPlay, Android Auto, digital radio, a 17-speaker Mark Levinson audio system, CD player (!) and shockingly sub-par satellite navigation.

Beyond that, Sports Luxury buyers also score tri-beam LED headlights with adaptive high beams, an informative 8.0-inch driver display, a heated steering wheel, sunroof, powered heated/vented front seats (with memory setting for the driver), a wireless charger, head-up display, keyless entry/start, powered steering column (including retraction for easier access), active noise-control tech, rear privacy glass with sunshades, a powered boot lid with kick sensor, semi-aniline leather with a choice of walnut trims, tri-zone climate control, powered/reclining/heated outboard rear seats with centre armrest climate and audio controls, 18-inch alloys and performance (but not adaptive, crucially) dampers. More on that later.

All Lexus models also include an ‘Encore’ aftersales subscription program offering myriad offers and services including 'free' car rental.

Everything but the cliché sink, then, but is the 300h SL actually good value for money?

No rival can match the Lexus’ mix of sheer size, hybrid efficiency, spec generosity and aftersales support.

But around that $80K mark, the cheaper yet roomier Skoda Superb and smaller Volvo S60/V60 and VW Arteon 206TSI all feature all-wheel drive, as do the classy Audi A4/A5 quattros, while the rear-drive-biased BMW 3/4 Series, Genesis G70 and Alfa Romeo Giulia are far more focused on character and athleticism. Serious competition all.

And, as we found out, none can be mistaken for a Camry. Image is important at this level.

Every Tank 500 Hi4-T PHEV has a 2.0-litre turbo-petrol engine, a 37.11kWh lithium-ion battery and an electric motor. And that combination produces a total* of 300kW and 750Nm. 

* Electric motor 120kW, petrol engine 180kW at 6000rpm. Motor 400Nm, engine 380Nm at 1700-4000rpm.

This system is mostly seamless in operation but as for GWM’s claims that it delivers “outstanding efficiency, performance, and refinement smooth, responsive take-offs, strong acceleration, and exceptional fuel savings - while ensuring minimal noise and maximum driving confidence”. Well, let’s just say this Tank 500 gets off the mark well for a large 4WD but the prompting requires a heavy right foot.

It is generally quiet and comfortable and yields a smooth driving experience. And as for fuel saving, flick your eyes down to ‘Efficiency’ to see how it did on this test.

This Tank 500 has a nine-speed automatic transmission, low- and high-range 4WD gearing, as well as a front, centre and rear diff lock.

Doing duty in a cornucopia of Toyota products, the ES 300h’s A25A-FXS engine remains the same as the pre-facelift model, meaning it is a 2487cc (2.5-litre), double overhead cam, 16-valve Atkinson Cycle in-line four-cylinder petrol unit with variable valve timing.

In this application, it makes 131kW of power at 5700rpm and 221Nm of torque between 3600rpm and 5200rpm, and sends that through to the front wheels via an e-Continuously Variable Transmission (CVT) with a sequential shift facility offering artificially stepped 'ratios' for a more-conventional automatic transmission sensation.

A series/parallel full hybrid system, the engine is backed up by a permanent magnet synchronous electric motor, delivering 88kW and 202Nm, and is fed by a tiny 1.6kWh Nickel-metal hydride battery pack.

With only a couple of kilometres of pure-EV driving availability, and only under light throttle or when coasting along, the latter is recharged via the petrol engine as well as recaptured energy from the regenerative braking system. Combined power output is 160kW. No combined torque maximum is stated.

With an impressive power-to-weight ratio of 92kW/tonne, the 1740kg 300h needs 8.9 seconds to reach 100km/h, and maxes out at 180km/h.

To handle all that movement and mass, the steering is an electrically powered rack and pinion set-up, the front suspension consists of MacPherson-style struts and the rear suspension is made up of a multi-link arrangement.

Official fuel consumption is 2.1L/100km on a combined cycle on regular unleaded fuel (91) with low-charge consumption at 8.4L/100km. For reference, low-charge fuel consumption on this test was 10.2L/100km as recorded. Okay, but not a particularly compelling result.

The Tank 500 has a 70-litre fuel tank so, going by those fuel figures, you could reasonably expect a driving range of about 686km out of a full tank.

Rated as Euro 6, the ES 300h requires a minimum brew of 95 RON premium unleaded petrol.

But that’s where the bad news stops, because over 626km of all sorts of driving in hot weather with the tri-zone climate control in full workout mode, we averaged an extremely commendable 5.6 litres per 100km. Well done, Lexus.

That’s against the official combined average of 4.8L/100km, which equates to just 109 grams per kilometre of carbon dioxide emissions. Not bad.

With the 50L tank brimmed, expect a real-world range of about 890km – or 1041km using the official average fuel consumption figure.

Either way, the 300h is mighty frugal for a 5.0-metre long and 1.8-tonne luxury machine. But cab and hire companies already knew that from their Camry hybrids, right?

The Tank 500 Hi4-T PHEV is decent on road – and that’s good news for anyone thinking about buying this large 4WD.

It has more power and torque than its hybrid stablemate (300kW/750Nm vs 255kW/648Nm) for general day-to-day drivability while it retains all of the regular hybrid’s positive driving characteristics and few of the negatives.

This Tank 500’s turbocharged petrol engine and the electric motor work seamlessly together, with no discernible clunking or shifting between systems in the powertrain.

This is a big, heavy four-wheel drive – even heavier in this plug-in hybrid form than the regular hybrid because of this vehicle’s battery. But it is nicely settled and composed because of that weight.

This flip side is the extra heft on-board means there is some body-roll to this vehicle. It’s noticeable, but not a deal-breaker.

On highways, sealed surfaces or well-maintained bush tracks the Tank 500 is quite impressive. It’s settled, controlled and quite nice to drive.

Overall, this Tank 500’s suspension – double wishbone independent with coil springs at the front, and multi-link live axle with coil springs at the rear – is firm. There has been talk of it having been retuned for Australian conditions, but it remains stiff and jittery at pace, especially through backcountry bitumen in poor condition and lightly corrugated dirt roads. However, GWM informs me that the suspension set-up will undergo more retuning for Australian conditions and those changes will be incorporated into 2026 production vehicles.

Besides that, the engine, electric motor and transmission work quite well together. It is a reasonably smooth 4WD wagon to drive.

There are, however, glaring issues with the driver-assist tech, which is quite annoying in its operation. It’s either very jarring or intrusive in its application (example: adaptive cruise control braking way too early), or bloody annoying/dangerous (example: road-sign recognition abruptly tried to cut my speed from 100km/h to 40km/h because it registered the school zone sign off to the side of the highway. At the time it was outside school drop-off and pick-up times anyway.).

You can switch off the driver-assist features every time you start up, but the system resets and defaults to being annoying again when you switch off.

When it comes to 4WDing though, the good news returns.

This hybrid retains all of the regular Tank 500’s 4WD mechanicals, including the (BorgWarner-sourced) transfer case with high- and low-range 4WD, and it offers up plenty of torque across a decent spread of revs.

The off-road traction control system is suitably dialled in, hill descent control is effective, keeping you to a nice controlled low speed and there’s low-speed cruise control or the equivalent that keeps the vehicle to a controlled pace across varying terrain.

Not forgetting, the Tank 500 is triple locked – front, centre and rear diff locks – so there are few excuses to not be able to crawl over most off-road obstacles.

However, the tyres on this vehicle (Giti Xross HT71 SUV - 265/60R18) aren't up to scratch when it comes to off-roading beyond anything other than well-maintained tracks in the dry. The Tank 500 as is well suited, straight out of the dealership, for light to moderate off-roading. But if you swap in a decent set of aggressive all-terrain tyres the Tank 500 will be able to more comfortably take on more challenging terrain.

But it's capable of climbing. I took on a 30-35 degree incline of rock steps and the Tank 500 did it easily and comfortably on its standard highway tyres.

Most of the plug-in hybrid Tank’s off-roading characteristics check out. Approach, ramp over and departure angles are as per the regular hybrid Tank 500 (30, 22.5 and 24 degrees) and wading depth is a listed 800mm although the country was so dry at our proving ground that I never had the chance to test that claim.

Ground clearance on the Tank 500 Hi4-T PHEV is listed as 213mm (it’s 224mm in the normal hybrid) but that doesn't negatively impact this vehicle's off-roading capability if you drive it with control and consideration.

It is big, so it can be a little bit tricky to steer around, especially when the track becomes tighter and the obstacles become a bit more cheeky, but generally this can be driven very safely and with the utmost control through a lot of tricky four-wheel driving challenges.

It's not as polished in its off-road performance as something like the Toyota Prado or Ford Everest, but it does the job and there's a bit of a gruff edge to it, which some people might consider part of its charm.

As mentioned, the Tank 500’s 37.11kWh battery supports Vehicle-to-Load (V2L) functionality, which in theory means you’ll be able to power your camp-site (lights, fridge etc), but I’ll reserve final judgement on this set-up until I have the opportunity to test it over a long weekend with several appliances drawing power at the same time.

If you’re thinking about using this Tank PHEV as an adventure touring vehicle then it’s handy to know its payload is listed as 610kg, while it’s noted as 790kg in the Tank 500 HEV. Throw two adults, two teenagers, a dog, and camping gear in and you’ll hit that 610kg mark in no time.

The Tank 500 is rated to tow a 750kg unbraked trailer and 3000kg braked. Gross vehicle mass is 3430kg and gross combined mass is 6430kg.

In the right conditions, the ES 300h is a big, squishy, comfy drive. At low speeds, for instance, thanks to an airtight cabin that does a great job isolating its pampered occupants from the outside world.

You cannot hear the car on start-up because the electric motor whirrs this Lexus off the line instantly, silently and effortlessly. And aided by all the surround-view cameras, the steering is light and direct enough to make parking a breeze. Automotive Valium to soothe your weary head after a long day.

Likewise, get the ES out on a smooth motorway and that relaxed feeling remains, with the 300h being right at home as it lopes along quietly and steadily. Cocooned in sumptuous leather and walnut, the adaptive cruise control gently rolling with the ebb and flow of traffic, it’s easy to zone out in here.

Find an empty stretch of road and you might also be impressed at how instantaneous the 300h’s throttle response is, leaping into action and piling on the speed without even breaking a sweat. This thing ain't slow!

Likewise, if you must hurry through a tight set of corners, the Lexus will remain composed and in control, without skipping a beat. Even the brakes seem well tuned and nicely modulated – something that many electrified vehicles struggle to achieve. It’s all so nice and easy.

So, what’s the catch?

First of all, while hushed when pussyfooting around, the illusion of posh sophistication is shattered once the accelerator pedal is prodded down hard, with the accompanying engine noise seeming incongruous.

Perhaps it’s because we’ve been lulled into an electric peace, but once the revs are up, no amount of sound-deadening will quell the mechanical roar.

And it's that same Camry hybrid symphony you've probably heard hundreds of times before, in the back of a taxi hurrying to the airport.

Except in the Lexus, it's far-more muffled. Like you're wearing headphones. 

Then there’s the question of bonding. While the ES 300h will do what’s asked of it capably and without complaint, there is nothing to connect car with driver.

By this, we mean that the steering is remote and feels numb at all times, with little to no feedback. Enthusiasts will search for the short way home. This is the anti-Alfa Giulia - technically a rival.

Most people will not care about that, but on the Sport Luxury’s 18-inch wheel and 235/45R18 tyre package – while modest by today’s standards – the ride quality is less than ideal on anything but smooth roads.

The ES can easily cope with small-frequency surface irritations, but seems to lack sufficient suppleness dealing with larger bumps and pot holes.

There’s an underlying and often unyielding firmness that undermines this car’s luxury aspirations. We’d dial back the taut handling for more cushiness if we could. Or fit a decent set of adaptive dampers.

Plus, the Dunlop Sport Maxx tyres aren’t as quiet as we’d expect on some of our coarser bitumen surfaces.

Comfy on smooth roads, fast when you need it to be, fit enough to go exactly where you point it to without losing composure, and wonderfully economical even when driven like it’s been stolen, the 300h has much to offer from a driving point of view.

But you won’t be aching to drive it just for fun’s sake. And you’ll quickly learn which roads are less than perfect in your neck of the woods.

Tested in 2018 under a less-strict regime, the ES delivers a maximum five-star ANCAP crash-test rating result. Back then, it scored especially strongly in Adult, Child and Vulnerable Road User categories, and quite well for Safety Assist tech.

There are 10 airbags in total (offering dual frontal, side chest, side head and front-occupant knee protection). The AEB system works between 10km/h and 180km/h, while the lane-tracing, lane-keep and emergency steering assist systems are operational from 50km/h to 200km/h.

Other driver-assist tech includes rear cross-traffic alert, blind-spot monitoring, adaptive cruise control with full stop/go and road-sign recognition and 'Intersection Assist' with 'Turning Assist'. The latter warns and brakes the car if the driver attempts to turn into oncoming traffic.

These are backed up by adaptive LED headlights with auto high beams, 360-degree view cameras, tyre pressure monitors and 'Lexus Connected Services' that can notify emergency services in an accident and track a stolen ES. An alarm with intrusion sensor is also fitted.

You’ll also find anti-lock brakes with brake-assist and electronic brake-force distribution, stability and traction control systems, three rear-seat child-seat tether anchorages and two ISOFIX latches, fitted to the outboard positions of the back bench.

The Tank 500 is covered by a seven-year/unlimited km warranty, seven years' roadside assistance and seven years' capped price servicing.

The Tank 500’s 37.1kWh traction battery has an eight year/unlimited km warranty.

The first service is scheduled at 12 months/10,000km; the rest of the servicing appointments are set for every 12 months/15,000km. Lowest price per services is $335, highest is $975.

GWM has 122 dealerships nationwide at time of writing.

Here is where Lexus really excels nowadays.

Since the beginning of 2021, it caught up with most other manufacturers by offering a five-year, unlimited kilometre warranty with roadside assistance – up from four-years and 100,000km previously. Free towing and loan vehicles are provided for that period, too.

Service intervals are at 12 months or 15,000km, whichever comes first.

The ES offers three years and 45,000km of capped-price servicing, with each one costing $495 – as well as a free loan vehicle and car wash.

Plus, there’s also Lexus’ ‘Encore’ aftersales subscription program offering myriad offers and services.
