Kia Rondo vs Lexus Rx450H+

What's the difference?

If you're thinking of getting an SUV because you like to sit a little higher up and want a car with plenty of room and a big boot, but don't head off-road ever, then you may be better off in a Rondo S which drives more like a car and has much of the benefits of an SUV.

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

The Rondo has a mini-people mover shape with a horizontal and high roof, an upright back and a heavily raked windscreen and pointy nose. The headlights look too big for its face but that's kind of cute in a manga-cartoon way.

Take a look at the dimensions for the Rondo S - it's bigger than you might think.  At 4525mm end to end it's 45mm longer than a Kia Sportage mid-sized SUV, and 35mm shorter in height at 1610mm tall. It's 35mm narrower than the Sportage, too, at 1805mm across. 

Clearance is about the same as a regular car at 151mm but the driving position is higher – though not as high as the Sportage's.

Inside the dashboard and steering wheel are low, the windscreen is enormous and those A-pillars either side of it are long.

On the outside you can tell a Rondo S from the top spec Rondo Si by the wheels – the S has plastic hubcaps and the Si has alloys. You can spot a Rondo S from the inside by the tiny media screen and the chunky plastic steering wheel – the Si gets a bigger screen and sleeker looking wheel.

The cabin is stylish with the brushed aluminium look trim and dark materials. The CarsGuide photographer told me he liked its '80s retro look – thing is I'm pretty sure the designers weren't trying to go for an ironic retro feel.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

The Rondo has enormous rear doors that are light and easy to swing open and when they do you have a wide and tall entrance which makes getting in and out easy. That's good news if you're not as agile or young as you used to be or if you're a parent putting kids into car seats. I find I almost double over when putting my toddler into his car seat in small cars, but the Rondo's seat height is elevated enough that there's less of a bend needed. The step to get in is low, too.

The second row is made up for three individual seats rather than a single bench seat. The legroom in all of them is excellent and even at 191cm tall I can sit behind my driving position with two finger-gap between my knees and the seatback.

Headroom is outstanding and even with my big hair I still have about 20cm of clearance.

The Rondo was already so impressively practical and roomy that it could have been terrible to drive and it still would be worth buying.

The cargo volume of the Rondo S is 536 litres, and that's 44 litres more than the boot space in the seven-seater Rondo Si which loses luggage capacity because of the foldable third row seats and 130 litres more than the Sportage's boot.

Under the boot floor is like a giant bento box of storage compartments with three equal-sized large rectangular areas big enough for handbags, shoes and laptops, a smaller shoe boxed-sized area and a tiny hidey hole big enough for my phone. Also in the boot on the right-hand side wheel are elasticised straps for – picnic blankets or whatever else you don't want flapping about in there.

There's shoe-boxed sized storage under the floor in the second row, on both sides, too.

The centre seat in the back folds flat and being hard-backed can act as a table, it also has three cup holders moulded into it. There's another two cup holders up front and giant bottle holders in all doors.

The Rondo is just as practical as many SUVs if not more so.

And here's a random Rondo fact for you – the Rondo is pretty popular with dog owners because the height of the roof means their hounds can stand up and turn around. Yup dogs love the Rondo.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

There are four variants in the RX range, and we’re testing the 450h+ Sports Luxury AWD, which sits just below the flagship and packs in plenty of premium kit for its $123,500, before on-road costs, price tag.

That makes it slightly more affordable than its main PHEV rivals; the BMW X5 xDrive50e (from $125,885 MSRP) and the Volvo XC90 Ultra (from $124,466 MSRP).

The Volvo does offer seven seats to the Lexus’ five, which may matter for larger families, and both rivals also outdo the RX on electric-only driving range - 65km in the RX compared with 77km in the Volvo XC90 and a generous 101km in the BMW X5.

Still, the RX fights back with a seriously stacked features list. Highlights include a panoramic sunroof, 10-way powered front seats with heating and ventilation, electrically folding rear seats (also heated and ventilated in the outboard positions), and a heated, power-adjustable steering wheel. Sound is taken care of by a premium 21-speaker Mark Levinson surround system.

Technology has had a solid upgrade with the 14-inch touchscreen multimedia display, 12.3-inch digital instrument cluster, digital rearview mirror, colour head-up display, live traffic navigation, wireless Apple CarPlay and Android Auto, 4G connectivity, four USB-C ports, one USB-A port and a fast wireless charging pad.

There’s also access to the 'Lexus Connected Services' app, allowing you to remotely lock or unlock the vehicle, pre-set the cabin temperature via three-zone climate control, configure driver profiles and even use your phone as a digital key.

Practical features include keyless entry and start, rain-sensing wipers, dusk-sensing LED headlights, rear sun-blinds, intelligent seatbelt reminders for the first two rows, a child presence alert and a hands-free powered tailgate. However, due to the plug-in hybrid system there’s no spare tyre, just a tyre repair kit.

There's one engine in in the Rondo range – it's a 122kW/213Nm 2.0-litre four-cylinder petrol and it comes with a six-speed automatic transmission. A manual gearbox isn't available.

You may hear the engine called a GDI, don't let then name throw you – it's not a diesel. The acronym stands for Gasoline Direct Injection.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

Kia says the Rondo's average combined fuel consumption is 7.9L/100km or 10.8L/100km if you're keeping it urban. Our test vehicle was thirstier and was driving at a rate of 10.1L/100km according to the trip computer over a week of highway and urban use, while our city commuting saw usage jump to 17.4L/100km.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

You know what? The Rondo was already so impressively practical and roomy that it could have been terrible to drive and it still would be worth buying, but its on-road performance was pretty impressive.

Look, the brakes can be a bit bitey, acceleration on take-off is sharp and then the engine seems to run out of oomph and just get noisier at higher speeds, but those are my only real complaints, because the ride is composed and comfortable, the steering feels smooth and light, while the handling is impressive. I took the Rondo through the same test loop as all my test cars and it performed better than many in this price range.

Being lower to the ground gives the Rondo better dynamics than many SUVs, too. Corners that cause a good degree of body roll and tyre chirp in a Sportage or RAV4 saw the Rondo coast through perfectly stable and unfussed.

The A-pillars do obstruct visibility and at one set of traffic lights, the only way I knew I had a green arrow was because the bloke behind me was leaning on his horn. But there are small port-hole windows integrated into the A-pillars that help with visibility.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

The RX earned a maximum five-star ANCAP safety rating in 2022, scoring highly across all protection categories: 90 per cent for adult protection, 89 per cent for child protection, 89 per cent for vulnerable road users, and 93 per cent for safety assist systems.

Standard safety gear includes eight airbags (dual front, front side, curtains, front centre, and driver’s knee) plus a comprehensive suite of driver aids. Standout features include emergency call functionality, child detection alert, side exit assist, front and rear collision warnings, park assist and emergency steering assist.

Additional tech covers blind-spot monitoring, driver attention monitoring, tyre pressure monitoring, daytime running lights, LED cornering lights, rear cross-traffic alert, lane departure alert, lane keeping assist, traffic sign recognition, and intelligent seatbelt warnings for the front two rows.

Visibility and parking are enhanced by a 360-degree camera system and front/rear parking sensors, while adaptive cruise control adds comfort on longer drives.

The rear seats have two ISOFIX mounts plus three top tether anchors, accommodating child seats safely. Autonomous emergency braking is active from 5.0 to 80km/h for pedestrians, cyclists, and backover and up to 180 km/h for cars.

The Rondo is covered by Kia's seven year/unlimited kilometre warranty. There's capped price servicing for seven years, too. Servicing is recommended every 12 months or 15,000km and is capped at $299 for the first service, $375 for the second, $361 for the third, $398 for the fourth, $336 for the fifth, $470 for the sixth and $357 for the seventh.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.
