Lexus IS300H vs Mahindra XUV3XO

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.

So, what do we make of the Mahindra XUV 3X0?

After our first taster in India, we are pleased with its presentation inside and out, packaging, quality and equipment levels.

And while driving around a brand’s own proving ground cannot give a true indication of how a vehicle performs, steers, handles, rides and stops, our initial impression is that this is an easy, confident, responsive, agile and comfortable small SUV from behind the wheel. More or less.

Of course, not knowing pricing limits a definitive verdict, but the 3XO looks promising, and we’re keen to drive it on Australian roads very soon, so watch this space.

Better still, it is obvious that Mahindra is serious about cracking Australia’s small SUV market, since the 3XO ticks so many of the essential boxes.

In the face of largely cheap yet disappointing rivals out there, that’s a very good thing.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, 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.

The 3XO is not quite as new as it looks.

Although only on sale in India since last year, the newcomer is actually based on the decade-old SsangYong Tivoli, which was the first model under Mahindra’s brief ownership of the Korean brand (now under KGM control since 2023).

And, if you’ve visited India lately, you might have seen a substantially modified Mahindra version of the Tivoli, badged XUV300 and sold for five years there from 2019, and the actual basis for the 3XO.

Now, Mahindra says that the latter is around 80 per cent new, with fresh sheetmetal clothing the bones of its predecessor(s). And they’re quite contemporary threads, with crisp surfacing, striking LED lighting, clean grille finishes and a pert rear-end design.

Subaru would be proud of the squared-off wheel arches, lofty 201mm ground clearance and sub-four-metre length, while the latter helps keep the small SUV inside an Indian tax bracket. Fun fact: that’s why the old Ford EcoSport, also from Chennai, needed its spare wheel mounted on the tailgate.

The 3XO's length/width/height/wheelbase of 3990mm/1821mm/1647mm/2600mm respectively, puts the 3XO on the stubbier side of the crossover brigade. Yet with more clearances than almost all alternatives. This is crying out for a rugged 4x4 ‘Outback’ treatment.

Overall, then, the smallest of Mahindras is an effectively chunky update, with a height and stance to handle the rough and tumble of urban driving.

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.

Mahindra reckons that even though the 3XO is only four metres long, it's got the space and the practicality of some 4.7m SUVs.

Which sounds dubious, but first impressions inside reveal ample room for legs, shoulders and heads, even in the sunroof-specced AX7L. Sat high, vision is impressive too, aided by an excellent driving position on nicely-shaped seats, deep glass areas and handy 360-degree camera views.

Based on the old dashboard architecture but with a completely redesigned central touchscreen and electronic instrumentation pod (and both measuring in at 10.2 inches), the effect is modern enough, with a very welcome avoidance of screen-based buttons for actual switches that are incredibly easy to navigate.

In fact, the sheer user-friendliness of the 3XO’s interior is commendable, from the world’s deepest glovebox and chilled centre bin (in the AX7L only) to the various USB ports, cupholders and storage options. The climate control effectiveness is a given if any Indian vehicle is to succeed. And the material fit and finish seemed fine. About the only dislike is the lack of steering-wheel reach adjustment, betraying the Mahindra’s real age.

Moving to the row behind, there’s sufficient space for a pair of 180cm adults, on comfy cushions. Again, vision, storage and all amenities rate highly, with face-level vents especially appreciated at this price point. The 3XO is pitched as a sensible family-car proposition in India so the back-seat area is crucial.

Behind that is the boot, which is fairly large as well, aided by a low floor and a large hatch aperture, while a space-saver spare lurks underneath, so no stupid tyre-repair kit for this sensible small SUV.

There’s also a lot of room under the bonnet…

At the time of publishing, XUV 3XO (here-on in referred to as 3XO) pricing hadn’t been confirmed. But, we’re instructed that the entry-level AX5L will start from “about $25,000”, placing it right among the sharks.

But Mahindra is out for blood, so keyless entry/start, synthetic leather trim, a 10.2-inch touchscreen and 10.2-inch driver display, wireless Apple CarPlay/Android Auto, a surround-view camera, dual-zone climate control, electric folding mirrors, roof rails and 16-inch alloys – with a spare – are included.

From “well under $30K”, the AX7L ushers in 17-sized rims, a panoramic sunroof, Harman-Kardon audio, a chilled glovebox, fog lights, front parking sensors and a shockingly powerful (pun intended) 65W USB-C port to (more than) make up for a missing wireless charger pad.

Lined up against its Chinese and South Korean rivals, the 3XO’s specification is largely on the money. Largely.

However, no DAB+ digital radio is an oversight, and although the Mahindra includes must-have advanced driver-assist safety systems (ADAS) like autonomous emergency braking (AEB) and lane-support tech, it misses out on some secondary nice-to-have alerts optionally available on some rivals – more on them in the safety section later on.

Now, if you’re thinking that the 3XO might look a bit familiar, your eyes aren’t deceiving you. And there’s a very solid reason for that.

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.

It might be tiny and a cylinder down compared to almost all of its Asian rivals, but Mahindra’s in-house 1.2-litre three-cylinder turbo-petrol engine follows European downsizing convention.

This means it relies on advanced technologies to produce comparatively healthy power and torque outputs, being 82kW at 5000rpm and 200Nm between 1500rpm and 3500rpm respectively.

Coming in at around 1400kg, the result is a power-to-weight ratio of about 59kW per tonne, which is modest against the slightly heavier Tiggo 4’s 76kW/tonne, for instance.

Driving the front wheels is a Toyota-made six-speed torque-converter automatic, so no droney CVTs or laggy dual-clutch transmissions here. But we’re disappointed the six-speed manual gearbox offered elsewhere isn’t even an option in Australia, especially after driving the Mahindra.

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.

The official Australian combined fuel consumption average is 6.5 litres per 100km, which translates to 137g/km of carbon dioxide emissions. With a 42L tank, should equate to about 640km per refill.

Urban and Extra Urban numbers are 7.6L/100km and 5.9L/100km respectively.  

Just keep in mind that the 3XO is recommended to drink from the 95 RON premium unleaded petrol bowser.

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.

There’s much made about how strong and rigid the 3XO’s platform is, and it’s not just for better crash protection.

Aided by a typical MacPherson-style strut front and twist-beam rear suspension set-up, Mahindra reckons it has dialled in just the right amount of dynamic finesse to make this small SUV the keen driver’s choice.

To find out if that’s the case, we spent a couple of hours behind the wheel of one at Mahindra’s vast proving ground near Chennai. A 180km/h high-speed loop. A set of chicanes. And a few rough surfaces where we could find them. Just a taster, really.

The overall impression is that nothing betrays the 3XO’s ageing platform from behind the wheel.

Torquey and smooth, the 1.2-litre three-cylinder turbo petrol engine is punchy off the line, possessing a sporty, peppy nature as well as an endearing willingness. Adding to this is the six-speed auto, as it’s also pleasingly responsive, with no lag or jolts. This is how small turbos should behave.

We managed to max it out at almost 170km/h (indicated) on the speed bowl, where it felt dead-set stable and secure. Impressive, given the 3XO’s height and ground clearance.

But the steering seems too light and a little disconnected during low-speed manoeuvres, at least for keener drivers, but once velocities climb, it seems to weigh up with sufficient heft. This is reminiscent of the way that Volkswagens used to tune its steering some 25 years ago. Maybe that’s the biggest sign of the Tivoli’s bones lurking underneath.

What this means is that the Mahindra is not the sort of SUV you buy if you absolutely relish driving, in the way the Mazda CX-3 or the very sadly-missed Ford Puma are. Hopefully, we’ll be pleasantly surprised on Australian roads.

We never got a chance to test the suspension’s ride quality, but over the couple of bumps that we did traverse, it seemed to soak them up well enough. And even though our test 3XO lacked the (optional) rear parcel shelf, road and tyre noise seemed sufficiently contained. Again, Australian roads will reveal all.

What we can say with some confidence is that the little Mahindra is a lively, user-friendly, comfort-biased and civilised small SUV. No glaring faults or anomalies appeared, just a cheerful, charming character.

For what it represents, the 3XO seems properly engineered and tuned.

Perhaps all those years ironing out the bugs in the preceding XUV300 and Tivoli are paying dividends for today’s buyers.

We weren’t expecting that.

No Australian or European NCAP crash-test rating exists for the 3XO.

But it does include AEB with cyclist/pedestrian detection, forward collision warning, lane keep assist, traffic sign recognition, lane departure warning, high beam assist and adaptive cruise control with Smart Pilot Assist, as well as six airbags.

Plus, ISOFIX fixings are fitted to the rear seats, along with a trio of child-seat anchorage points.

However, neither grade offers rear cross-traffic alert and a blind-spot monitor, meaning the XUV 3XO may struggle to achieve a five-star ANCAP crash-test rating at this time.

That said, it recently scored five stars in India’s new (but less-stringent) Bharat NCAP test, aided by extensive body strengthening and crash-force mitigation engineering development at Mahindra’s world-class research and development centres in India.

And there’s still more safety development underway, ahead of next year’s planned ANCAP test.

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.

Mahindra offers a seven-year warranty with roadside assistance, and that is excellent news for most buyers. But the 150,000km cap when most other brands have unlimited mileage might fall a bit short for some prospective buyers’ requirements.

At the time of publishing, no service scheduling and capped-price servicing pricing information was available, but expect these to be announced after early July 2025.
