Kia Stonic vs Lexus LM 500H

What's the difference?

All in all, the Stonic is a satisfactory daily driver, it’s just nowhere near ideal as a modern urban conveyance.

Sure, it’s reasonably priced in an increasingly expensive market, but it is very sluggish off the mark which is a solid negative against its overall rating. It also feels cheap inside and lacks contemporary driver-assist tech, such as adaptive cruise control.

The Lexus LM 500h is luxurious, comfortable, practical, easy to drive and expensive. While it may appear to be the ultimate family car, with only four seats it's limited in terms of how many kids and their friends you can carry. On top of that, the privacy screen introduces accessibility issues to the kids you wouldn't encounter on other vehicles. If you are thinking of a Lexus people mover as your next family car I'd suggest looking at the LM 350h which has seven seats and no privacy screen. If you’re looking at a business class executive van the LM 500h would be perfect. 

I spend the lion’s share of my time in large and upper large 4WDs, so spending quality time in something like this little hot hatchbac… er, small SUV, is a revelation and a lot of zippy fun. Like driving a go-kart without the fumes and the prangs.

The 2025 Kia Stonic Sport is 4140mm long (with a 2580mm wheelbase), 1760mm wide and 1520mm high. It has a listed kerb weight of 1227kg.

This is a slick-looking hatchbac… er, light SUV, and it looks suitably sporty. 

Though ground clearance is unlisted, it stands well clear of the road surface, giving this hatchbac… er, compact SUV, more presence than it otherwise might have.

The LM 500h doesn't look real. More like a concept vehicle with its vertical face wearing that enormous grille. Feels like if you watched it for long enough you’d catch it transforming into some kind of robot. Yet, at the same time its styling is elegant and prestigious.

I have a confession to make. I used this Lexus as my office. Its interior is that comfortable and spacious. I'm also a parent and there were times where it was the quietest place to get some work done.

It also let me observe people's reactions as they walked past with their dogs not knowing what was going on inside behind those tinted windows. The people that noticed were clearly car enthusiasts as they knew what they were looking at and couldn't pass without gaping it awe.

The LM 500h’s interior is superbly plush with thick carpets, beautiful copper metallic trim and nappa leather seats.

As I’ve said, the cockpit up front is less luxurious than the extravagant first class section in the back behind that dividing wall.

And yes, I’ve seen large screens before but nothing that stretches the width of the vehicle.

The Stonic Sport’s interior is a practical space but it feels a bit dated and underdone in a car market increasingly packed with well-equipped, cheaper and more contemporary SUVs.

The most obvious factors working against the Sport are its the 8.0-inch touchscreen multimedia (too small), the absence of wireless Apple CarPlay and Android Auto and wireless phone charging and multiple hard plastic surfaces.

Sure, the touchscreen is easy enough to operate, but it sometimes takes a few finger stabs to hit the sweet spot you’re after, and thankfully there are dials and buttons off-screen as alternatives for air con controls, etc.

There’s a satisfactory number of storage spaces in the front including two cupholders between the seats, a few little receptacles for your everyday carry gear, and bottle holders in each of the front doors.

The back seat is short on cupholders – there are none – but there are bottle holders in the doors, and the passengers back there get a USB-A port, a map pocket (in the back of the front passenger’s seat) and flip-down grab handles. There are no directional air vents.

Back-seat room is satisfactory for an adult without being spacious, but fine for kids. What do you expect in a small SUV?

In terms of packability, the cargo area (with the rear seat up and in use) yields a listed 352 litres of space. The rear seats are in a 60/40 split fold configuration and with them folded down there is a listed 1155 litres of useable room.

The rear cargo area has bag hooks, a storage space in the left-hand inner wall, and tie-down points at each corner of the floor.

A steel space-saver spare wheel is under the cargo area floor.

You might be able to take Lexus out of Toyota but it's very hard to take Toyota out of Lexus and this particularly applies to the practicality of the LM 500h.

Every day I discovered new compartments, tray tables and storage areas. There are so many cabinets, lockers and hidey holes that we almost left my belongings (an entire family of plushie toy capybaras) behind because there are so many places to check.

Of course, I'm talking about the rear compartment here because up front there's not much storage. In fact, it proved to be quite a problem in that I had nowhere to put my bag with somebody sitting next to me and no area behind the front seats to stow it, either.

Talking of seats, the LM 500h only has four of them, with two up front and two in the rear. Up front, the seats are supportive and large, but the rear seats - those are, well... have a look at the images.

We’re talking two large captain's chairs that look as though they’ve been removed from the first class section of a plane.

And while this might be suitable for businesses shuttling a couple of executives to and from meetings, for a family, even with two children, the extra couple of seats a third row offers would come in handy.

The LM 350h has seven seats over three rows and no privacy screen. A far better choice for families.

For device charging there are USB ports up front and in the rear. There are wireless phone chargers for those in the back seats but not up front.

The LM 500h has a cargo capacity of 752 litres with all seats in place.

The Lexus LM 500h sits at the top of its range and is without a doubt one of the most expensive people movers on Earth with its list price of $220,888.

As you would imagine the standard features list is as extensive as it is extravagant.

For starters, while the regular LM 350h has two rows of seating in the rear (seven seats all up, including the front two), the 500h has the third row removed and just two super luxurious and enormous fully reclining seats fill the entire space. It’s like a theatre back there.

That theatre theme keeps going with a media screen in the back so large it stretches the width of the vehicle. Seriously, it's a 48-inch screen to watch movies or connect to your device.

The sound system is probably the best I’ve experienced - a spine tinglingly incredible 23-speaker Mark Levinson set-up.

What else can I tell you? Those rear seats are upholstered in beautifully soft semi-aniline leather. They’re heated and ventilated with a massaging function and... ridiculously comfortable.

There’s four-zone climate control, windows which have an electronic shade that turns the glass opaque, there are wireless phone chargers in the doors and carpet throughout so thick you sink down into it as you step inside.

Our LM 500h was upholstered in the 'Solis White' leather which also brings contrasting and mesmerising copper metallic trim.

Oh, and there’s a wall with an electric glass screen that can be raised or lowered to separate the rear passengers from the driver.

I should have mentioned this earlier. The kids loved it, but these parents spent a lot of time telling the 10- and three-year old not to put the screen up again.

The rear occupants, aka the kids, can also lock the screen in place. Which they did, and so sound proof is the dividing wall that we can only just hear their uproarious laughter.

Up front, the cockpit is comfortable but it’s clear all the space and luxury is for those being driven around.

Still, the front seats are leather with heating and ventilation, there’s a 14-inch media screen and 12.4-inch digital instrument cluster, plus a head-up display. Sat nav, Apple CarPlay and Android Auto are also standard.

The 2025 Kia Sonic Sport has a 1.0-litre three-cylinder turbo-petrol engine – producing 74kW at 4500-6000rpm and 172Nm at 1500-4000rpm – and that’s paired with a seven-speed dual-clutch automatic transmission. 

This pairing is a mostly punchy one, although definite lagginess is evident from a standing start often enough that it’s a disconcerting characteristic rather than a mildly annoying one.

This turbocharged engine used to only be offered in the top-spec GT-Line, so it’s a welcome addition to the other grades.

The LM 500h is a petrol-electric hybrid with a 2.4-litre four-cylinder turbo-petrol engine which makes 202kW/460Nm and works in concert with two electric motors.

The front motor makes 64kW/292Nm and the rear makes 76kW/169Nm. The combined maximum power output of the two motors and the petrol engine is 273kW.

The LM 500h is all wheel-drive and has a six-speed automatic transmission.

Kia's official fuel consumption figure for the Stonic Sport is 5.4L/100km, on a combined (urban/extra-urban) cycle. And on this test I recorded 8.2L/100km.

The Stonic Sport has an 45-litre fuel tank so, going by my on-test fuel figure, you could reasonably expect a driving range of about 548km from a full tank. 

Fuel requirement is 91 RON 'standard' unleaded.

Lexus says after a combination of urban and open roads the LM 500h should use 6.6L/100km. In our own testing we found consumption was higher at 9.4L/100km.

Worth noting my driving environment was mainly a hilly suburban one filled with school drop offs. Achieved some personal bests this week, with one long run to Sydney’s outskirts, only to return in nightmarish peak hour traffic.

Premium (95 RON) fuel is required and the tank size is 60 litres. In theory the driving range is a smidge more than 900km, which drops to around 640km using our real-world average.

The Stonic Sport is a handy urban conveyance, but it is far from perfect.

It’s a small, light vehicle so it’s nimble for navigating through car-packed streets and convenient for tricky parking manoeuvres.

Steering is well weighted and precise.

And the turbocharged petrol engine is a welcome addition to the Stonic package, introducing a handy amount of power and torque which is sensibly harnessed and delivered – most of the time anyway – via the mostly clever transmission.

However, in stop-start, inner-city traffic or even a busy suburban area, the Stonic Sport struggles to get off the mark from a standstill, so much so that this one characteristic threatens to spoil the rest of the driving experience. 

Once the Sport is out on the open road, it’s a pleasant cruiser as this compact SUV simply rolls along.

Ride is firm – 17-inch wheels and low-profile tyres are the culprits here – and handling is impressive.

In terms of refinement the Stonic is mostly, um, fine but there is some tyre noise, especially over rougher roads out of the city, but it’s not terrible.

Every Stonic has three drive modes – 'Normal', 'Sport' and 'Eco' – each of which tweaks throttle response, engine output and transmission settings to best suit the driver and conditions. 

The Stonic is generally a reasonable daily driver, but the absence of adaptive cruise control is a let-down when it comes to highway running.

Not that you’ll be buying a Stonic with the aim of skull-dragging a 3500kg caravan along the highway, but it’s handy to know this Kia SUV’s towing capacities are 450kg (unbraked trailer) and 900kg (braked).

Quite simply, driving the LM 500h is like piloting a limousine on stilts. Superbly comfortable, but with an elevated driving position that offers outstanding forward and side visibility, the LM 500h is an easy vehicle to drive for long periods of time.

A digital rear vision mirror means visibility behind is good and unobstructed by the privacy screen or the seats.

The drawbacks are down to the lack of space up front, with the driver’s chair limited in its ability to recline or slide back due to the bulkhead behind it.

And that's compounded by the lack of cabin storage for bags if the front passenger seat is taken.

As for the rear passengers there aren't many people movers offering this level of comfort, except perhaps the Zeekr 009.

Variable suspension that adjusts continuously keeps the vehicle composed and provides a high level of comfort for those in the rear. At the same time, the LM stays nice and flat through roundabouts while remaining civilised over speed bumps.

And then there's the acceleration, which, while not supercar-like is incredibly brisk for a van. The all-wheel drive system provides outstanding traction in wet and slippery conditions, too. 

Our family used the LM daily for everything from school runs to shopping trips and weekends away and not only was it fun to drive, our lucky rear passengers enjoyed sitting high and being able to see clearly out their windows along with the luxury of a giant movie screen.

The Lexus  LM 500h is yet to be tested by ANCAP so it doesn't have a safety assessment score. There is, however, a high level of safety tech onboard including AEB which can detect pedestrians, cyclists, motorcyclists and other vehicles, emergency steering assist, lane keeping assistance, road sign recognition, rear cross-traffic alert, front and rear parking sensors as well as six airbags.

For child seats there are ISOFIX points and top tether anchor mounts on the two rear seats. We have a forward facing child seat and found it easy to install.

A space-saver spare wheel is located under the boot floor.

Kia’s seven-year/unlimited kilometre warranty applies to the Stonic and you have access to roadside assistance for up to eight years as long as you always get it serviced at an authorised Kia garage.

Servicing intervals are set at every 12 months or 10,000km, whichever comes soonest.

Service costs start at $290 (12 months/10,000km), peak at $727 (48 months/40,000km) and finish at $578 (84 months/70,000km) and the total over seven years is $3367; an average of $481 per workshop visit (correct at time of writing). That’s rather pricey for something in the small SUV market.

Lexus covers the LM 500h with a five-year, unlimited kilometre warranty. 

The Lexus Encore Platinum program is complimentary for LM owners for three years, providing 24-hour roadside assist, a loan vehicle or pick-up/return service at service time, 'On Demand' vehicle evaluation options, valet and airport parking benefits as well as exclusive offers and event opportunities.

Servicing is recommended annually or every 15,000 kilometres, and impressively, pricing is capped at $695 per service over five years.
