Lexus ES300H vs GWM Cannon Alpha

What's the difference?

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.

The Cannon Alpha Ultra PHEV combines five-star safety, a confident warranty, lavish luxury and short-haul electric driving for a competitive price. However, from a pure workhorse perspective, its class-benchmark 3500kg tow rating is offset by a modest payload limit, plus an awkward spare tyre location which could be a deal-breaker for some tradies as it compromises working floor space and the securing of loads.

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.

Our test vehicle shares the same body-on-frame chassis design, twin A-arm/coil-spring front suspension, four-wheel disc brakes and electric power-assisted steering as the model it replaces, but the previous leaf-spring live rear axle has been replaced by a multi-link coil-spring arrangement. External chrome has also been greatly reduced.

Its luxurious leather-accented interior has a spacious and classy feel with a panoramic sunroof and opulent mix of surface finishes, but some tradies might consider such indulgences too fancy for carting muddy-booted crews.

The PHEV’s larger rechargeable battery pack uses up all the underfloor space behind the rear axle usually occupied by a full-size spare tyre. As a result, the steel-rimmed spare has been moved to a conspicuous location in the load tub, which not only looks like an afterthought but is far from ideal for workhorse duties (see Practicality).

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.

Our test vehicle’s substantial 2810kg kerb weight is 235kg heavier than its hefty Alpha Hybrid predecessor, due largely to the bigger battery and electric motor. That makes it about half a tonne heavier than numerous conventional turbo-diesel 4x4 dual cab utes.

This substantial kerb weight contributes to a sizeable 3495kg GVM, yet results in a 685kg payload rating which is modest compared to some turbo-diesel rivals with genuine one-tonne capabilities.

It’s also rated to tow up to the class-benchmark 3500kg of braked trailer, but with its 6745kg GCM (or how much it can legally carry and tow at the same time) that would require a 250kg reduction in payload (from 685kg to 435kg) to avoid exceeding the GCM.

While it’s unlikely owners would need to tow at the 3500kg maximum, it’s important to be aware of these numbers if the need arises, as that 435kg of payload could easily be used up by a crew of tradies before you could load any of their tools.

The vertical mounting of the spare wheel in the load tub not only reduces floor space and load volume but also restricts the securing of loads, given there’s no anchorage point accessible in the right rear corner of the tub.

So, all load straps extending rearwards must share the same left-side anchorage point, which is far from the ideal even spread provided by four-corner load restraint. This spare wheel location needs a rethink (perhaps a swing-away carrier favoured by 4x4 wagon owners would be better).

We also noted the big button on the two-way tailgate, which enables it to split into a pair of hinged doors, stopped working during our test. Fortunately, it could still open the tailgate as a conventional single unit.

There’s ample interior space, not only for front seat occupants but also those in the back. That includes tall people, given I’m 186cm and have at least 40mm of knee room when sitting behind the driver’s seat when set in my position.

There’s also about 80mm of rear headroom, despite the presence of a full-length sunroof which can often compromise this dimension. However, shoulder-room is tight for three adults, so two would be preferable for long trips.

Front-of-cabin storage includes a large-bottle holder and bin in each front door, plus a large glove box, overhead glasses holder and a pull-out compartment for the driver in the lower dash.

The centre console offers wireless phone-charging and a lidded box (with internal air-con flow available) and two small-bottle/cupholders. Another storage nook in the lower right-side of the console offers two USB ports, a 12-volt socket and enough space for a phone.

Rear passengers get a large-bottle holder and bin in each door, pockets on the rear of both front seat backrests and small pull-out drawers under each outer seat. The rear of the centre console also offers adjustable air-vents, a pair of USB ports plus controls for seat heating/cooling and the sliding rear window.

The fold-down centre armrest offers another wireless phone-charging pad, pop-out twin cupholders and a hidden compartment for storage of phones or other slimline items.

Our Ultra test vehicle, which sits above the entry-level Lux as the premium PHEV model grade, comes in only one specification comprising a 4x4 hybrid drivetrain with four-cylinder turbo-petrol engine, electric motor and plug-in rechargeable battery for a list price of $64,990.

That pricing sits between its local PHEV ute rivals including the BYD Shark 6 ($57,900) and Ford's entry-level XLT Ranger PHEV ($71,990). Our example’s 'Crystal Black' premium paint is a $595 option.

Its generous standard equipment includes 18-inch alloys with 265/60R18 tyres and a full-size steel spare, LED headlights/DRLs/fog lights/tail-lights, two-way 60/40-split tailgate with electronic lock, roof rails, side-steps, rear privacy glass with electric-sliding rear window, a panoramic sunroof, front and rear diff locks, tyre pressure monitoring, front/rear parking sensors and lots more.

The luxurious interior offers sumptuous leather-accented seating, with the front buckets having multiple power adjustments, heating/cooling and a massage mode. The outer rear seats also have heating/cooling, plus powered backrest recline and a ‘welcome’ function for easier passenger access.

There’s also a synthetic leather-wrapped steering wheel with heating, multiple 'feel' modes and functions, plus an electronic parking brake, head-up display, dual-zone climate, 64-colour ambient interior lighting and wireless phone charging/USB ports front and rear.

Cabin tech includes a 12.3-inch driver’s digital instrument cluster and premium 10-speaker ‘Infinity’ sound system, controlled by a big 14.6-inch multimedia touchscreen with Apple/Android connectivity, voice commands and a vast choice of settings which allow a high degree of personalisation.

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.

The Alpha PHEV drivetrain consists of a 2.0-litre, four-cylinder, turbo-petrol engine that produces 180kW of power and 380Nm of torque. This is paired with an electric motor that adds another 120kW/400Nm, so combined they officially produce 300kW and 750Nm.

The electric motor draws its energy from a 37.1kWh lithium-ion rechargeable battery. GWM claims it can be charged from 30 to 80 per cent in less than 30 minutes using 50kW DC charging, or around 6.5 hours using AC charging.

It also has up to 6.0kW of V2L (Vehicle to Load) functionality, using a dedicated adapter cable which plugs into the vehicle’s charging port and provides a standard three-pin AC outlet for numerous electric tools and appliances.

The nine-speed torque converter automatic, which offers sequential manual-shifting using steering wheel-mounted paddles, is paired with the familiar Borg Warner ‘Torque on Demand’ 4x4 system.

For road use, this has three selectable drive modes ('Standard'/'Sport'/'Eco') with the centre differential remaining unlocked to automatically adjust torque delivery between the front and rear wheels in response to any loss of traction.

For off-road use, selecting '4H' (4x4 High Range) or '4L' (4x4 Low Range) locks the centre differential to provide an even 50:50 torque split between the front and rear wheels. 4L traction can be optimised by engaging the front and rear diff-locks.

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?

GWM claims official combined average consumption of only 1.7L/100km when the highly-charged battery allows most driving to be done in pure electric mode. GWM also claims an official ‘low charge’ figure of 7.9L/100km, when the battery is depleted and the petrol engine is doing most of the work.

It has an NEDC electric-only driving range of up to 115km and a ‘hybrid’ driving range (petrol engine and electric motor combined) of up to 1060km. The petrol engine drinks standard 91 RON unleaded.

The dash display was showing average petrol consumption of 6.4L/100km at the completion of our 324km test, which comprised a mix of suburban, city and highway driving of which about one third was hauling a heavy payload. This was lineball with our own figure of 6.2 based on fuel bowser and tripmeter readings.

Starting with 90 per cent battery charge, we completed 72km of electric-only driving before it automatically switched to hybrid mode when the charge reached 14 per cent. The system would not allow charge to drop lower than that for the remainder of our test, which was conducted in hybrid mode.

So, based on our own test figures, GWM’s claim of more than 1000km of hybrid driving range is credible from its combined 37.1kWh battery and 75-litre fuel tank capacities.

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.

It has good steering feel with sophisticated ride quality, the latter thanks to four-coil suspension and substantial sprung weight which helps iron out the bumps and deliver a ride that’s more SUV than ute.

Flatten the accelerator from a standing start and up to 750Nm of torque responds with impressive force, even though you can feel that every one of those Newton metres is required to overcome more than 2.8 tonnes of inertia to get this jigger moving swiftly.

Although the option of sequential manual-shifting is available using the steering wheel paddles, we spent most of the test in auto mode as it felt like it was getting the best out of this complex drivetrain.

It’s a competent highway cruiser, too, with the petrol engine requiring 2200rpm to maintain 110km/h with low noise levels.

To test its GVM rating we forklifted just over half a tonne (505kg) into the load tub, which with driver equalled a 600kg payload that was less than 90kg under its limit. The rear coil springs compressed about 50mm, but there was no evidence of bottoming-out on our test route.

Ride, handling and braking were largely unaffected, along with the drivetrain which made light work of our 13 per cent gradient, 2.0km set climb at 60km/h.

Engine-braking on the way down, in a manually-selected second gear, was equally impressive. It never exceeded the 60km/h speed limit, even though its total vehicle weight of around 3.5 tonnes was being restrained by only a 2.0-litre four and regenerative braking.

The Cannon Alpha has a maximum five-star ANCAP rating (tested 2024) that includes seven airbags, 360-degree camera with multiple views and the active features you’d expect including AEB, front/rear parking sensors, front/rear cross-traffic alert with autonomous braking, speed sign recognition and more. The rear seat has three top-tethers plus ISOFIX child-seat anchorages for the outer seating positions.

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.

Warranty cover is seven years/unlimited km with an eight years/unlimited km traction battery warranty and seven years of roadside assist.

Scheduled servicing is every 12 months/15,000km whichever occurs first. GWM offers seven years of capped-price servicing totalling $4615, or an average of $659 per service.
