Lexus IS300 vs Mahindra XUV3XO

What's the difference?

The new-look Lexus IS takes several steps forward over its predecessor - it’s safer, smarter, sharper to look at and still pretty well priced and equipped.

It is feeling its age inside, and the competition has moved on in terms of engines and EV tech. But even so, if I was buying a 2021 Lexus IS, it would have to be the IS350 F Sport, which is just the most fitting version of this car, though the IS300h Luxury does have plenty to like for the money, too.

The fact this is Australia’s cheapest SUV is a massive feat for the Indian brand. It also has so much standard kit so this is even more surprising.

In many ways the XUV 3XO is better to drive than its rivals. The three-cylinder turbo engine has plenty of charm and moves this car along with ease, the car feels confident and composed out on the open road, and there aren’t any bings and bongs from intrusive safety systems.

However, things aren’t perfect. I wish the steering column offered reach adjustment, the steering feel wasn’t so inconsistent and the lane-keep assist wasn’t so hands-on.

If you can overlook these quibbles, this tiny Mahindra is an outstanding value buy if you’re considering a first new car.

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

You either get the Lexus look or you don’t, and I think this latest version is possibly more agreeable than the IS in years gone by.

That’s partly because the brand has finally done away with the odd spider-eyes twin-section headlights and daytime running lights - now there are more traditional headlight clusters, which look a lot more resolved than before.

The front end still features a bold ‘spindle’ grille, which gets different treatment depending on the grade, and the front, to my eye, looks better than before but still very much stuck in its ways. 

At the side you’ll notice the giveaway windowline hasn’t changed, despite the chrome trim line having broadened as part of this facelift, but you can tell the haunches have muscled up a bit, with the new IS now 30mm wider overall, and the wheel sizes are 18s or 19s, depending on the grade.

The rear accentuates that width, with an L-shaped lighting signature now spanning the entire re-sculpted boot lid, giving the IS a pretty tidy rear end design.

Overall dimensions for the IS are 4710mm long, making it 30mm longer nose to tail (on an unchanged 2800mm wheelbase), while it now spreads across 1840mm (+30mm) and is 1435mm tall (+5mm).

The exterior changes really are impressive - I think it is a more purposeful but also more pleasant looking car now than it ever has been in this current generation. 

The interior? Well, there’s not a whole lot to talk about in terms of design changes, aside from the repositioned and larger media screen - which sits 150mm closer to the driver because it’s now a touchscreen with the latest smartphone mirroring tech. Otherwise it’s a carryover affair, as you can see from the interior pictures.

From outside it’s surprising just how small this SUV is. At just under four metres long, the XUV 3XO is shorter than a Mazda2, for example.

The reason for this is because in India there are tax breaks for vehicles under four metres long. The Ford EcoSport, sans the tailgate-mounted spare wheel, was another SUV that met this requirement.

As a result of being so short, this has made the rear overhang virtually non-existent. It’s a strange look, especially because the bonnet is so much longer.

Even though the XUV 3XO is based on the KGM Tivoli (formerly SsangYong Tivoli), which was briefly sold in Australia, you’d be hard-pressed to find visual similarities. The former looks more modern from the outside and has more visual interest with the chunky wheel-arch cladding and diamond motifs.

At the front it’s hard to not see the face of a sad panda. The LED headlights are big and plunge down the front fascia, giving it a droopy and sleepy appearance. It’s not helped by the thick black bar connecting them.

Around the side the diamond-cut alloy wheels are a nice touch, along with the contrast black-painted roof on this AX7L tester.

The rear end is a little on the flat side, though the badging is tasteful. I’m not a fan of the full-width LED light bar, however, as it’s an overdone design cue now.

Inside I appreciate the mix of both old-school and new-school. There are dual 10.25-inch screens ahead of the driver for the digital instrument cluster and touchscreen multimedia system, as well as plenty of physical buttons and knobs for shortcuts and the climate controls.

For such an affordable car I’m surprised how many soft-touch finishes there are in this car. In the AX7L you get an extended use of synthetic leather on the door cards and dashboard, which helps make for a pseudo-premium look and feel.

However, one of my biggest gripes with the XUV 3XO interior is the amount of glossy piano black. It’s on the dashboard, centre console, door cards and even the steering wheel.

This may look cool and slick when you pick the car up from the dealer, but it shows up dust quickly and then gets scratched when you try to wipe it clean. Our tester had fewer than 1000km on the odometer and the centre console was already scratched to the wazoo.

The interior design of the IS, as mentioned, hasn’t changed dramatically, and it is starting to feel old compared to some of its contemporaries.

It’s still a nice place to be, with comfortable front seats with electric adjustment and heating across all grades, and cooling on many variants, too. 

The new 10.3-inch touchscreen media system is a nice unit, and means you can essentially do away with the silly trackpad system that still resides near the gear selector, so you may still end up bumping it accidentally. And the fact the IS now has Apple CarPlay and Android Auto (though neither are wirelessly connectable) does further its appeal on the multimedia front, as does the standard 10-speaker Pioneer stereo - though the 17-speaker Mark Levinson unit is an absolute blinder!

The centre stack below the media screen retains a CD player, and still has the electromagnetic temperature adjustment sliders as well. That part of the design is dating it just as much as the transmission tunnel console area, which looks a bit out of touch by modern standards, though still incorporates a pair of cup holders and a reasonably large centre console bin with soft armrest padding.

The front doors feature trenches with bottle holders as well, while in the rear doors there is still no drink storage - a carryover annoyance from the pre-facelift model. However, the middle seat in the back doubles as an armrest with pop-out cupholders, and there are rear air vents too.

Speaking of that middle seat, you wouldn’t want to sit in it for long, as it has a raised base and uncomfortable backrest, plus there’s a huge transmission tunnel intrusion eating into leg and foot space.

Outboard passengers also miss out on toe room, which - for my size 12s - is an issue. And it’s hardly the roomiest second row in this class for knee room and headroom, as my 182cm frame was a touch squished behind my own driving position.

Children will be better catered for in the back, and there are two ISOFIX anchorages and three top-tether attachment points for baby seats.

The boot capacity varies on the model you buy. Choose an IS300 or IS350 and you score 480 litres (VDA) of cargo capacity, while the IS300h has a battery pack that robs it of some boot space, with 450L available. 

Given this SUV is tiny, I’m blown away at how much interior space it has.

Up front both the seats are manually adjustable, which is to be expected at this price point. Despite this, they’re still comfortable and offer an elevated driving position which is something SUV buyers seek.

In front of the driver is a leather-wrapped steering wheel which feels nice in the hand. While it offers tilt adjustment, it disappointingly doesn’t have reach adjustment. This is frustrating if you’ve got long legs and short arms, like myself.

The 10.25-inch digital instrument cluster has an overall dark and minimal look, but you can cycle through a range of informative views. There’s even one that allows you to display a full-width map.

Moving across, the 10.25-inch touchscreen multimedia system appears to be snappy enough. I’ve experienced fewer glitches in this car than in previous Mahindras I’ve driven.

I like the physical shortcut buttons underneath the touchscreen because it allows you to jump around to key sub-menus a lot easier.

As standard there’s both wired and wireless Apple CarPlay and Android Auto connectivity. With my iPhone 15 Pro Max the connection was flawless and only dropped out during known interference points.

This AX7L spec comes with a seven-speaker Harman Kardon sound system which gets this tiny car booming. The subwoofer in the boot is so powerful it almost feels like overkill.

In terms of storage up front there are two cupholders, big door pockets with two bottle holders, a centre armrest and a cooled glovebox. There’s also a USB-A port, 65W USB-C port and a wireless charger.

Moving to the second row there’s a decent amount of space for adults to sit behind adults. You could easily fit two adults along the rear bench, though pushing it to three would get a little too squishy.

Second-row amenities include rear air vents, a USB-C port with a phone slot, as well as a fold-down armrest with cupholders.

At the back there’s a manual tailgate, which is to be expected at this price point, but finding the trigger to open it is a little tricky. It’s a small button that’s hidden away.

Once the tailgate is open, the amount of boot space on offer is generous. Mahindra claims there’s 364 litres with the rear seats upright.

While the loading lip is high, the boot area is deep and wide. Unfortunately there’s no cargo cover available as standard, which means you’ll need to be careful what you boot back there.

Under the boot floor there’s a space-saver spare wheel, which is fantastic peace of mind if you travel long distances away from tyre repair shops.

The Mahindra XUV 3XO is currently Australia’s cheapest SUV.

There’s a caveat, however, because this is thanks to an introductory pricing offer that ends on August 31.

Currently though, the XUV 3XO line-up starts at $23,490 drive-away for the AX5L and extends to $26,490 drive-away for the AX7L, as tested here.

After August 31 the drive-away asking price of both of these XUV 3XO variants is set to go up by $500. This will see it share the title of Australia’s cheapest SUV with the Chery Tiggo 4.

Despite the affordable asking price, Mahindra has packed a lot of standard kit. This includes 16-inch diamond-cut alloy wheels, 10.25-inch digital instrument cluster, 10.25-inch touchscreen multimedia system, wireless Apple CarPlay and Android Auto, six-speaker sound system, dual-zone climate control, electric park brake with auto-hold, keyless entry and push-button start, leather steering wheel and gear selector and black cloth upholstery.

For an extra $3000 in the AX7L you get a black-painted contrast roof, 17-inch diamond-cut alloy wheels, LED front fog lights, panoramic glass sunroof, seven-speaker Harman Kardon sound system, 65W USB-C charger, cooled glovebox, black synthetic leather upholstery, and synthetic leather on dashboard and door trims.

The engine specs depend on the powertrain you choose. And at a glance there’s no variance between the earlier version of the IS and the 2021 facelift.

That means the IS300 model still runs a 2.0-litre turbocharged petrol motor producing 180kW of power (at 5800rpm) and 350Nm of torque (at 1650-4400rpm). It has an eight-speed automatic transmission, and like all IS models, it is rear-wheel drive (RWD/2WD) - there is no all-wheel drive (AWD/4WD) model here.

Next up the spectrum is the IS300h model, which has a 2.5-litre four-cylinder Atkinson cycle petrol motor teamed to an electric motor and nickel metal hydride battery pack. The petrol engine is good for a 133kW (at 6000rpm) and 221Nm (at 4200-5400rpm), and the electric motor produces 105kW/300Nm - but the combined total maximum power output is 164kW, and Lexus doesn’t provide a maximum torque figure. The 300h model runs a CVT automatic transmission.

The big horsepower offering here is the IS350, which runs a 3.5-litre petrol V6 engine, producing 232kW of power (at 6600rpm) and 380Nm of torque (at 4800-4900rpm). It runs an eight-speed auto.

All models have paddle-shifters, while the two non-hybrid models have seen tweaks to the transmission software that is said to “estimate driver intentions” for better enjoyment. 

All variants are powered by a 1.2-litre turbocharged three-cylinder petrol engine that produces 82kW of power and 200Nm of torque.

This is mated to an Aisin-sourced six-speed torque-converter automatic transmission with drive sent to the front wheels only.

There’s still no diesel model, no plug-in hybrid and no full electric (EV) model - which means that while Lexus was at the forefront of electrification with its so-called “self-charging” hybrids, it is falling behind the times. You can get plug-in versions of the BMW 3 Series and Mercedes C-Class, and the Tesla Model 3 plays in this space in full-electric guise.

As for the fuel-sipping hero of this trio of powertrains, the IS300h is said to use 5.1 litres per 100 kilometres on the combined cycle fuel test. In reality, our test car’s dashboard showed 6.1L/100km across a mix of driving.

The IS300 with its turbocharged 2.0L engine is next best for fuel use, claiming 8.2L/100km. On our short launch drive of that model, we saw 9.6L/100km on the dashboard.

And the full-fat IS350 V6 petrol claims consumption of 9.5L/100km, while on test we saw 13.4L/100km.

The emissions for the three models are 191g/km (IS300), 217g/km (IS350) and 116g/km (IS300h). All three are Euro 6B compliant. 

Fuel tank capacity is 66 litres for all models, meaning your mileage range for the hybrid model could be considerably longer.

Mahindra claims the XUV 3XO has a combined urban/extra-urban fuel consumption of 6.5L/100km.

During my testing, however, I achieved a real-world fuel consumption figure closer to 6.2L/100km, which is better than the claim.

All XUV 3XOs have a 42L fuel tank that Mahindra claims can take 91 RON regular unleaded petrol, but 95 RON premium unleaded petrol is recommended.

With my as-tested fuel consumption this means the theoretical driving range from a full tank of petrol is around 675km.

With the engine at the front and drive to the back, it has the ingredients for a pure driver’s car, and Lexus made a bit of a big deal about the new-look IS being more focused thanks to chassis adjustments and track width improvements - and it does feel a pretty nimble and tied-down car in the twisty stuff. 

It is competent at stitching together a series of corners, and the F Sport models are particularly adept. The adaptive suspension in those models includes both anti-dive and anti-squat tech, which is designed to make the car feel solid and flat on the road - and it does, thankfully without feeling twitchy or uncomfortable, with good suspension compliance even in the most aggressive Sport S+ drive mode.

The 19-inch wheels on F Sport models are fitted with Dunlop SP Sport Maxx rubber (235/40 front, 265/35 rear) and there’s plenty of tarmac tenacity.

The grip from Luxury-spec models on 18s could be better, with those Bridgestone Turanza tyres (235/45 all around) proving not quite the most enthralling. 

Indeed, the IS300h Luxury I drove felt very different in character to the F Sport IS300 and 350 models. It was surprising how much more of a plush-focused model the Luxury grade feels, and likewise it wasn’t as impressive in dynamic driving due to the tyre grip and less-enthusiastic drive mode system. The non-adaptive suspension is a touch more jittery too, and while it’s not to the point of discomfort, you might expect better for a car on 18s.  

Across all models the steering is accurate and direct enough, with predictable response and decent feel to the driver’s hands for this electric power steering setup. The F Sport models have even further retuned steering for “an even sportier drive experience”, though I found at times it could feel a little numb for rapid changes of direction. 

As for engines, the IS350 is still the pick. It has the best zest, and feels the most fitting powertrain for this model. It sounds good, too. The auto transmission is pretty clever, there's easily enough pulling power, and it's probably going to be the last of the non-turbo V6s in Lexus's line-up when this cars life-cycle is up.

The IS300's turbo engine was the most disappointing, lacking some urge and constantly feeling bogged down by turbo lag, transmission confusion, or both. It felt underdone in enthusiastic driving, though in dull day-to-day commuting circumstances it came across as more acceptable, though the remapped transmission software was far less impressive in this application than in the IS350.

The IS300h was a lovely, quiet and refined experience all around. It’s the one you should go for if you don’t really care about all that go-fast stuff. The powertrain is proven, it accelerates with nice linear delivery, and at times it’s so hushed I found myself looking down at the instrument cluster to see if the car was in EV mode or if it was using the petrol engine. 

Behind the wheel, the Mahindra XUV 3XO feels refreshingly old-school.

The 1.2-litre turbocharged petrol engine does seem like it would be underpowered, but in practice it’s completely adequate. Peak torque comes on tap from 1500rpm so it doesn’t have to work too hard at all.

It’s fun hearing the noise the three-banger makes when under the boil. You don’t hear it much though because the revs are typically kept down low to minimise fuel consumption.

The key reason why this car feels old-school is the six-speed torque-converter automatic transmission. It’s nice to not drive an affordable everyday car that doesn’t have a continuously variable transmission (CVT) or dual-clutch automatic transmission as these can suck the life out of a car or be jerky.

The gear shifts in the Mahindra are sometimes docile, but are smooth and measured. It just operates like a regular car that doesn’t require you to rewire your brain to drive.

There are three drive modes to choose from. They’re hilariously called ‘Zip’, ‘Zap’ and ‘Zoom’. These correspond to Eco, Normal and Sport, respectively.

While I did eventually get used to driving in the ‘Zap’ mode, it felt a little snoozy at points, taking a beat or two to get the car accelerating with traffic. You can sidestep this with ‘Zoom’ which feels much more lively. If you activate cruise control or restart the car, though, it defaults back to ‘Zap’.

The XUV 3XO makes the most sense in the city where you’re able to use its tiny exterior dimensions to navigate tight urban carparks and narrow laneways with ease.

It almost became a challenge for myself to find the smallest parking spot I could slot this car into. As standard on this AX7L there are front and rear parking sensors, as well as a surround-view camera system.

Where this car is let down, however, is the steering feel. It’s incredibly light at low speeds and then as the speed builds it gets very heavy. So much so it feels like I’m getting an arm workout.

Unlike some of its rivals, there is still a semblance of feel through the steering wheel, but this drastic change from light to heavy steering weight is too stark. Somewhere in the middle would be nice please.

Something Mahindra is very good at is developing a comfortable suspension tune and this car is no different. It can tackle pimply urban road imperfections and speed bumps with no problems whatsoever.

Out on the open road this car surprised me. It feels like a much larger car than it actually is and doesn’t get blown around in the lane like small cars can.

The three-cylinder turbo-petrol engine remains confident at higher speeds, though if you frequently travel up hills the fuel consumption will skyrocket. There’s also a bit of road noise, which is to be expected when a car is this small.

For the most part the suspension does a fantastic job at rounding out road imperfections, but bigger bumps or potholes can unsettle the car. It’s not helped by the larger 17-inch alloy wheels.

Out in the twisties this tiny SUV is fairly agile. It’s not the sportiest thing out there by a vast degree, but it remains planted and solid even when pushed into harder corners.

Lastly, another point that makes this car feel old-school is the lack of obtrusive bings and bongs from the safety systems.

Sure the parking sensors can be a little over-the-top and the traffic sign recognition takes over the entire digital instrument cluster when it picks up a new speed limit, but having no driver attention monitor and intelligent speed limit assist is refreshing.

It’s not all perfect however as the lane-keep assist is too hands on for my liking. It activates from 60km/h and is quite overt in how it directs the car through bends.

The Mahindra XUV 3XO hasn’t been crash-tested by ANCAP just yet.

It was, however, tested by India’s less stringent Bharat NCAP testing authority in 2024 and received a five-star rating.

Standard safety equipment includes autonomous emergency braking (AEB), lane departure warning, lane-keep assist, lane centring, adaptive cruise control, traffic sign recognition, rear parking sensors and a reversing camera.

Stepping up to the AX7L gets you a surround-view camera, blind-spot view camera, and front parking sensors.

Notably absent from the entire range is rear cross-traffic alert, as well as a traditional blind-spot monitor that alerts you when a car is in your blind-spot.

There are two ISOFIX points on the two outboard rear seats, as well as three top-tether child seat anchorages across the rear bench.

On paper, Lexus’s ownership offer isn’t quite as enticing as some other luxury car brands - but it has a strong reputation for blissful ownership.

The Lexus Australia warranty period is four years/100,000km, which is better for duration than Audi and BMW (both three years/unlimited km) but not as accommodating as Mercedes-Benz or Genesis, each of which offer five-year/unlimited km warranty.

The company has a three-year capped price servicing plan, with maintenance every 12 months or 15,000km. The first three visits cost $495 each. That’s okay - but Lexus doesn’t offer free servicing like Genesis, and nor does it offer prepaid service plans - for three to five years for a C-Class, and five years for Audi A4/A5, for instance.

There is complimentary roadside assistance for the first three years, too.

That said, the company has its Encore ownership benefits program that allows a number of experiences and deals, and the service team will collect your car and return it, leaving you with a loan car if you need it.

Like other current Mahindra models, the XUV 3XO is covered by a seven-year, 150,000km warranty with seven years of roadside assistance.

Logbook servicing is required every 12 months or 15,000km, whichever comes first, though the first service is required after 12 months or 10,000km.

The first seven services are capped-price and total $1994. This averages out to $284.85 per service.
