Lexus IS300H vs Mazda CX-60

What's the difference?

Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.

While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.

Have no doubts. The MY25 version of the CX-60 is the SUV that Mazda should have launched in Australia in 2023.

It fulfils the promise of its sophisticated specification, builds on the extensive dynamic abilities of previous models, and now provides a compelling – and unique – choice for medium-SUV buyers who do not need an extended seven-seater.

It may still looks a bit daggy from some angles outside, and we’d like a little bit less suspension noise on the inside, but the CX-60 should now be on Australian family-car shortlists.

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

Look closely and quite a lot has changed. This is really a story of doing a facelift right. Lexus has kept all the great-looking bits of the car that launched in 2013, like its striking side profile and angular accents, while dumping most of its least popular elements like the spidery front light-clusters and busy front splitter, in favour of something more refined and conservative.

It even adds some new flair in the rear three-quarter, with dramatic LED light-clusters working their way into a trendy highlight strip across the boot lid.

These changes all add up for a much tougher, sportier, and nuanced design compared to the outgoing car. One that manages to make an eight-year old design look as contemporary as ever.

I even liked our test car in its plain black shade, although I'm less sure about those conservative-to-a-fault, almost Camry-esque alloy wheels.

On the inside, sadly not a whole lot has changed. The busy design looked dated when this generation of IS launched in 2013, and it still looks dated now.

The visual assault of buttons, toggles, displays, textures, and trims is a lot to take in, and makes the cabin feel smaller than it is.

It probably didn’t help the sensory overload of this car’s interior as I hopped out of the stripped-back interior in the Tesla Model 3 I had the week before.

My less-than-impressed brother, a student of design, described the IS’s interior best when he told me “It’s a bit maximalist, don’t you think?”

If nothing else, at least Lexus hasn’t blatantly imitated anyone else when it comes to its interior, but the brand remains firm on dorky design items like the laptop touchpad, redundant drive-select dial, and odd vacant panels under the climate unit which do it no favours.

A welcome upgrade for the 2021 model year is the new media screen, a highlight piece perched atop the dash. It’s bright, has excellent contrast, and doesn’t seem to fall victim to glare.

The Apple CarPlay support I used was seamless and sharp and made the most of the available real-estate in its widescreen layout.

I somehow didn’t mind that the instrument cluster in this base car is analog. It almost suits the IS’s character better than a digital set-up would. Also offered is a small information display between the dials which I used for monitoring the hybrid drive.

A final note on the IS’s design. The fit and finish is quality, inside and out. It leaves you with an impression that this is an immaculately built vehicle, one that should be a must for all luxury cars, and always a strong point for Lexus.

If you’re searching for something new in the looks department for the CX-60, you won’t find it, since this is essentially the same car as last year’s model from the outside. Except there’s a new beige colour option.

Which means the same long-bonnet/cab-backward silhouette remains, along with the corporate wing-motif grille, hunched-over styling (that looks awkward from some angles) and short rear overhangs.

Still, the overall effect remains modern, clean and distinct from the nearly-identical and very closely-related CX-70, CX-80 and CX-90 further up the Mazda food chain.

Note that the CX-60 is usefully larger than the CX-5, with the former coming in at 4740mm long, 1890mm wide, 1675mm tall and 2870mm in wheelbase length, compared to the latter’s 4575mm, 1845mm, 1680mm and 2700mm dimensions respectively.

Which, of course, elevates it from an interior point of view.

Well, the IS is a sedan, so it doesn’t quite have that high-riding appeal of an SUV, and for this update it has even leaned further into its low-slung proportions with a roofline that descends a further 15mm and a boot lid which is 31mm lower overall.

As with the previous car, the interior is quite closed-in thanks to that busy dash design and large centre console. Rather than feeling claustrophobic though, it is best described as cosy, with lots of plush finishes throughout the doors and centre stack befitting a luxury nameplate.

Adjustability is great for the front two occupants and there are two large bottle holders between the seats, a large but shallow console box under the armrest, bottle holders with adjoining bins in the doors, and a smallish glove box.

That’s about where storage ends though, with no extra trays or bins in front of the oddly placed shifter, just an awkwardly finished plastic panel where it feels like a little tray or storage cutaway should be.

The touchpad for operating the media screen joins an unnecessary drive-select cluster in eating up centre console space where there could be more storage.

The rear seat is quite limited on space despite being lavishly trimmed. I fit behind my own (182cm/6'0") driving position with little knee or headroom to spare.

Again, it’s cosy and very comfortable, but if you're taller or wider than me you may run into issues.

The centre rear seat is all but useless for adults, with the IS’s rear-drive architecture necessitating a huge transmission tunnel that almost comes as high as the seat base itself.

Storage is limited to pockets on the back of the front seats, small bins in the doors that double as handholds, and a drop-down armrest with two bottle holders.

There are no power outlets for rear passengers, but there are dual adjustable air vents.

Boot space is 450L which is a little small for the class. It’s impressive the hybrid only managed to lose 30 litres compared to petrol-only IS variants, though, so best to count your blessings.

The largest CarsGuide travel case easily fit in the wide but short available space.

Like the exterior, the changes for the MY25 CX-60 are pretty much under the skin, with improved noise/vibration and harshness-quelling measures to quieten things down more.

And an exhaust-sound enhancer through the audio system to liven things up if you desire.

Representing the aforementioned $10K saving over the previous entry-level Evolve, the Pure does possess less opulent trim and (nice) cloth seat fabrics, but otherwise the CX-60 does present a larger-than-usual cabin environment compared to smaller medium-sized SUVs.

But fans of big, showy screens may be underwhelmed.

The dash is elegant but somewhat old-fashioned, especially compared to, say, the latest BMW X3’s dazzling displays. It feels like a hangover from last decade’s CX-9.

Yet there’s no denying how satisfyingly easy and logical most of it is, from the super-clear, electronic instrumentation to the simple and effective climate control layout, while the iDrive-style rotary controller means less time with eyes off the road. Safe, intuitive ergonomics. Thank you, Mazda.

Additionally, there’s a quality solidness to the fit and finish that elevates the social-climbing Mazda beyond what a CX-5 could achieve.

All the essentials are also well thought out, from storage and vision out to ventilation and, not least of all, space and seat support, especially when sat on over long distances.

That also carries over to the expansive back-seat environment, with air vents, USB ports, lighting, cupholders and grab handles. The CX-60 is an SUV that a family could grow into without it feeling excessive.

Is this ‘big-medium’ or ‘small-large’ sized?

From the boot’s perspective, either fits, and is one of the reasons why you might consider stepping up to a CX-60. The floor is low, wide, flat and easy to load, as well as beautifully finished.

The 40/20/40 split fold backrests can be folded remotely via Mazda’s Karakuri function, boosting capacity from 477 litres (VDA) to 1726L, while the in-line six-cylinder models have a space-saver spare wheel underneath, leaving PHEV owners with an inadequate tyre repair kit.

Starting from $50,240 (all prices are before on-road costs) for the Pure grade in G40e six-cylinder turbo-petrol-powered guise that should account for nearly half of all sales, this is the new base grade.

It has lost some items compared to the previous entry-level Evolve, but remains a decently-equipped proposition.

Included are LED headlights with auto high beams, keyless entry/start, dual-zone climate control, cloth trim, a 10.25-inch display/touchscreen, a 360-degree view camera, front/rear parking sensors, satellite navigation, wireless Apple CarPlay/Android Auto, DAB+ digital radio, eight-speaker audio, vehicle-exit warning, folding/heated exterior mirrors and 18-inch alloy wheels.

There’s also a decent level of advanced driver-assist safety technology like autonomous emergency braking, lane-support systems and adaptive cruise control. More on those later.

Moving up to the Evolve from $55,240 scores you a larger touchscreen (12.3-inches), ground-view monitor, artificial leather trim, a wireless charger, powered tailgate and a few extra safety features like front-cross traffic alert and a driver monitor, while the new Touring grade from $58,240 gains leather trim and heated/powered front seats with driver’s side memory.

Climbing up to the GT from $64,240 adds adaptive LED headlights, panoramic sunroof, Bose 12-speaker audio upgrade, a powered/heated steering wheel, hands-free tailgate operation, heated rear seats, glossier trim and 20-inch alloys, while the Azami from $68,440 includes Nappa leather, glitzier finishes, vented front seats and more.

Speaking of more, $2000 extra buys you a white interior with unique woven textiles (Azami Takumi pack) or a sportier tan colour edition (Azami SP pack).

Want more economy? Diesel adds another $2000 while going for the PHEV powertrain ups that by a whopping $11,050 across all grades. We’re grateful for the choice, Mazda.

These certainly sound expensive for a mid-sized SUV from Japan, but the CX-60 is considerably larger and roomier than, say, a CX-5 or Toyota RAV4, and possesses a level of sophisticated engineering that puts it in Audi Q5, BMW X3, Lexus NX, Mercedes-Benz GLC and Volvo XC60 territory – and the least-expensive of these kicks off from upwards of $20,000 more, depending on spec.

As a sub-luxury premium proposition, then, the CX-60 lives in a sort of no-man’s land. Yet its styling certainly reveals where Mazda’s aspirations lie.

The IS 300h does stand out from the luxury sedan crowd by offering a hybrid drivetrain at a reasonable price. Some rivals offer plug-in options further up the price scale cementing them as a niche option, but the beauty of this Lexus is its very mild $3000 price jump over the base petrol car.

The base car’s 2.0-litre turbo is dumped in favour of a 2.5-litre non-turbo Atkinson-cycle four-cylinder hybrid set-up similar to the one proving popular in the Toyota Camry and RAV4.

The petrol engine produces 133kW/221Nm on its own, and the electric motor produces 105kW/300Nm. Toyota says the “combined system output” of this is 164kW.

Either way, that's less than the base 2.0 turbo. The 300h also swaps out an eight-speed torque converter automatic in favour of a continuously variable transmission. Rare in a rear-wheel drive car.

For now, the base engine is the 209kW/450Nm G40e, a 3.3-litre turbo-petrol ‘six’ delivering the sort of healthy power figures that late-model Commodore and Falcon buyers would appreciate.

There’s also the 187kW/550Nm D50e turbo-diesel version, for extra pulling power and economy, and we’re getting into premium Euro territory here, because both offer a 48-volt, mild-hybrid system, employing a small electric motor located behind the engine to boost torque yet cut fuel consumption and CO2 emissions.

Mazda says new motor control and clutch slip control software facilitates “…smoother transitions as the electric motor is activated and deactivated”. We hope so!

Last but not least, there’s the 241kW/500Nm P50e plug-in hybrid electric vehicle powertrain, combining the familiar 2.5-litre four-cylinder petrol engine with a larger, 129kW electric motor powered by a 17.8kWh Lithium ion battery. The latter allows up to 76km of pure-electric driving, and can be recharged either by regenerative braking when driving or plugged into a Type 2 port.

All three engines use a revised eight-speed, wet multi-plate-clutch automatic transmission, still driving the rear or, as traction and/or performance needs arise, all four wheels.

Yep, this is essentially a rear-drive-biased family SUV, with a sophisticated double wishbone front and multi-link rear suspension set-up to keep everything in line.

So, what’s changed underneath compared to last year’s CX-60?

Among the modifications are stiffer dampers and softer rear springs to address ride-comfort issues with the old car; relocated front knuckle mounts; altered rear axle bushes and the removal of the rear anti-roll bar for more stable control; shorter rear bump stops for greater suspension travel; an extra joint in the steering column quells vibrations while updated software improves steering feel and electronic stability control operation. The goal is for noticeably smoother, comfier and more linear dynamics. 

Result? To find out how much better or worse Mazda’s latest mid-sized SUV is, we drove the it in a variety of conditions, from the push-and-shove of Melbourne’s bumper-to-bumper peak-hour traffic, to a series of demanding emergency-swerve and multi-speed ride and handling test manoeuvres at the legendary Lang Lang proving ground that shaped so many of our iconic Holdens.

More on that a bit later on.

As you might hope this hybrid IS has an astoundingly low official/combined fuel consumption rating of 5.1L/100km.

I was pleased to find that after a week of mainly urban driving conditions, our IS was returning a figure of 6.9L/100km. Not bad at all, especially for a class where fuel consumption can get a little out of hand with turbocharged engines or V6s.

Of course, using the hybrid system to your advantage over the long term will get this number much lower, as I discovered on my long-term test of the Toyota Corolla hybrid which essentially uses a smaller version of the same system.

Certainly, if fuel consumption is a high concern, you’re better off with this car than the top-spec V6 (IS 350) which will easily see consumption enter double digits.

Lexus recommends a minimum RON rating of 95 for the IS 300h, and the fuel tank is 66 litres regardless of variant, giving the hybrid an impressive theoretical range of around 1000km.

One area where the Mazda did not need fixing is in its fuel economy.

All of the CX-60’s powertrains are rated at Euro 5.

Officially, the G40e 3.3-litre petrol averages 7.4L/100km, on the combined cycle, and emits 174 grams per kilometre of CO2. Urban and Extra Urban numbers are 9.9L/100km and 6.0L/100km.

Fitted with a 58L petrol tank, expect an average range of around 780km. And it will run on standard 91 RON unleaded petrol to boot.

Moving on to the D50e 3.3L diesel, it manages an impressive 5.0L/100km, for a CO2 figure of 132g/km, resulting in a range average of about 1160km. Its Urban/Extra Urban figures are 5.5/4.7L/100km respectively.

And, finally, there’s the P50e 2.5L PHEV, offering a theoretical 2.1L/100km, for a CO2 figure of just 49g/km, for an unlikely range average of 2380km from its 50L tank, though on 95 RON premium unleaded brew.

Out in the real world, and mostly driven harder than a typical owner might, the trip computer in the PHEV showed low sevens, while the diesel displayed mid-eights and the petrol high nines, which aren’t too bad at all.

There is no doubt the IS 300h is capable. You can feel it through the car’s solid rear-drive underpinnings, silky smooth steering, and reactive chassis.

What this car doesn’t offer is excitement in quite the same sense as many of its rivals. That’s down to this hybrid’s drivetrain. It just doesn’t have that powerful follow-through in the same way turbocharged BMWs or Audis or Mercedes do.

If it’s that 'sports luxury' experience you’re seeking better off looking to the base 2.0-litre turbo or the V6 and their eight-speed automatics.

The 300h does offer something a bit different. The gentle refined efficiency of Toyota’s signature hybrid system in a luxury rear-drive package that’s smaller than this car’s ES bigger brother.

While it may feel capable thanks to the lighter suspension components and altered track that the brand has committed to for this update, the hybrid drive matches this car’s softer character brought about by its gentle suspension tune and light steering.

This is an easy car to drive around a city, it filters out bumps nicely, while offering near silence in the cabin and breezy steering for every day scenarios like manoeuvring in tight parking lots.

The CVT auto and instantaneous torque available from the electric motor make it best at traffic speeds, being both reactive and predictable, with silent acceleration when inching forward at the lights or cruising along at 50km/h.

As you might expect though, the wheezy Atkinson cycle engine and CVT conspire for a noisy and less than engaging experience under heavy acceleration.

It’s not as though you’re rewarded with particular vigour either, with this combination being a bit sluggish when a lot is asked of it.

It loses its reactivity and refinement at higher speeds or in the corners on country roads as the transmission elastically tries to keep up with the demands of the driver.

Still, few luxury sedans are quite as purpose-built for the toils of a city, and if you want to get drawn into this car’s hybrid drive antics, it’s easy to make a game out of saving fuel by trying to rely on its low-speed electric motor capability.

Really then, it leans into its urban luxury appeal. A luxury sedan for the streets of Tokyo. An ideal car in this class for the urban environment.

If you don’t care for the thrill of a turbocharger or frequently seek to explore the twists of your nearest B-road, you could do worse than the comfort and ambiance the 300h offers.

This is the acid test. Does the CX-60 drive like a Mazda should?

In the engine department, definitely.

The changes that Mazda has made to the transmission calibration means that it no longer hunts indecisively between ratios like it used to, and that results in smoother shifts as well as a more relaxed driving experience.

And that's across the range, whether we're talking about the six-cylinder diesel or petrol, or four-pot plug-in hybrid. And the latter brings the biggest surprise, because the changes made to the gearbox have resulted in a much more pleasant car around town, with no more shunting or jerky movements to contend with.

And then there's the ride, which is palpably softer than before. The suspension is significantly more pliable and comfortable as a consequence, offering better bump absorption, improved control at speed and basically just a more refined experience. We tried several of the Lang Lang Proving Ground’s rough-road tests, which the CX-60 sailed over without any of the hard jarring of the previous model, which Mazda helpfully provided for back-to-back assessments.

So, how does all that translate in everyday driving?

Well, the latest CX-60 is way more comfortable to ride in across the board, it handles and corners with greater control and linearity, seems quieter and it's just a suppler experience overall.

As there was so much that was good with the original CX-60 anyway, including muscular performance from the inline six-cylinder turbos, impressive high-speed stability and exceptional body control through fast turns, the modifications for 2025 do much to elevate an already good thing.

So, it's a win-win situation. If you are in the market for a sub-premium, mid-sized SUV with performance and space, as well as newfound comfort and sophistication, you can do a lot worse than check out the CX-60. It is that much better than before.

Thankfully, the CX-60 isn’t frugal on safety, scoring a five-star ANCAP crash-test rating back in 2022.

An extensive suite of driver-assist tech is standard, and it’s all nicely tuned for Australian roads, unlike some Chinese vehicles we’ve tested and that’s an important distinction.

These include autonomous emergency braking (AEB) for cyclists, pedestrians and in back-over situations, blind-spot monitoring, vehicle exit warning, lane-departure, lane-assist and emergency lane-keep tech, driver attention alert, forward obstruction warning, rear cross-traffic alert, turn-across traffic and adaptive cruise control tech with full stop/go.

However, front cross-traffic alert, 'Cruising/Traffic Support' (that assists drivers in slow-moving traffic with automatic accelerator, brake and steering control to maintain a safe distance from the vehicle ahead) and see-through view front camera are not in the Pure. Adaptive LED headlights and drowsy driver alert only start from GT up, while emergency brake assist is for the Azami grade only.

All CX-60s include front and rear parking sensors, surround-view cameras, tyre pressure monitors and traffic sign recognition.

The AEB for vulnerable road users works between 10km/h and 80km/h, and the AEB car-to-car operates between 4km/h and 160km/h.

Likewise, the extensive lane-support systems work between 55km/h and 195km/h.

There are also eight airbags, as well as a trio of child-seat restraining top-tether points fitted, along with two ISOFIX latches in the rear outboard seats.

Lexus gets slightly ahead of the luxury pack with an extra year of warranty. While BMW and Audi still sit on three, Lexus offers four, but it is limited to 100,000km and is still outdone by Mercedes-Benz and Korean newcomer, Genesis, offering five-year/unlimited kilometre promises.

The IS has capped price servicing fixed at $495 for the first three years of ownership with roadside assist, and the brand will even pick up and drop off your car, or offer a free loan car during every 12 month or 15,000km service.

It’s worth noting that German rivals offer pre-paid service packages out to five years, and Genesis is trying to make a splash with free servicing.

Lexus does offer a luxury ownership program dubbed ‘Encore’ which includes invites to experiences and certain partnerships with restaurants and the like to keep potential owners enticed.

Mazda could also do a bit better with its warranty nowadays, since its five-year/unlimited kilometre warranty and roadside assistance is decidedly average.

Service intervals are at 12 months or every 15,000km, while a fixed-price service scheme is available, starting from $463 per service depending on powertrain. That’s for the petrol. The diesels start from $500 while the PHEVs commence from $435.
