Kia Ev3 vs Lexus Rx450H+

What's the difference?

The GT-Line is relatively expensive, yes. The Air Standard Range isn’t groundbreaking even at under $50,000, no. But the sweet spot in the EV3 line-up is being able to pay $53,315 for the Air Long Range and come away with a roomy small SUV that can realistically cover almost 600km in the real world.

And it does everything properly, no big red flags or dealbreakers.

Its steering weight at speed on winding roads being the biggest complaint isn’t the end of the world for how otherwise comfortable the EV3 feels on-road.

Put it this way - I recently spent a few days in a Mini Aceman, a five-door electric SUV not too far from the EV3 in size. It is about as fast, and costs a little more, but it doesn’t have a lot more to offer in terms of features and it’s nowhere near as good on range with about 400km to its longer-ranged versions.

The EV3 might still have a bit of ‘sensible’ about it compared to some other electric small SUVS, but when it looks this cute and can get you an extra round trip out of the city compared to ‘Euro’ brands at the same price, it’s hard not to be impressed.

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

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.

Family resemblance is everything for Kia’s electric models, and the baby of the bunch so far definitely has lineage on show.

That’s a very good thing for the EV3, because as good as its specs are on paper, the way it looks is key to showroom (or on-road) appeal when it comes to convincing potential buyers.

At the same time as being seemingly made of sharp, angular elements, the EV3’s overall silhouette is relatively soft. Unfortunately, that means Kia’s ‘design philosophy’ (usually a relatively meaningless marketing line) is actually bang-on: Opposites United.

Inside and out, the EV3 is a direct descendant of the brand’s halo EV9 large SUV, and even in base Air specification looks like a properly premium small SUV.

Its narrow LED headlights and taillights were the stuff of Lamborghini concept cars just a few years ago, and its unique wheel designs and the use of contrasting coloured trim can impose either a modern, techy vibe or a bark-over-bite sporty image.

More marketing terms come out in the EV3’s face: Kia Star Map lighting and Tiger Face, respectively the way its lights seem to link ‘points’ together like a constellation map and the grille somewhat resembling a tiger’s nose.

There’s practicality in the design even from the outside - the gentle roof slope is only very slight to avoid eating into interior space, though it’s not the only way the car shrinks at the rear. The front track between the wheels is actually wider than at the rear, so the car is not only shorter but also narrower at the rear. It’s the first time Kia has ever implemented this ‘teardrop’ effect into a car, with the intention being to improve its aerodynamic efficiency.

Most of the colour schemes are decidedly subtle, the new Matcha Green hue looks better in person than can be captured on camera for example, but a new Teracotta colour is an earthy red that really stands out - I’m not sure it suits the car, personally.

In terms of colours inside, it's fairly muted and greyscale, but the mid-spec Earth comes with optional orange interior contrast trim that we weren’t sure would be available in the Australian market.

To invoke a cliche, the interior layout has the vibe of something you might imagine a spaceship cockpit looks like if you were a kid, but it doesn’t sacrifice any practicality by doing so. There are real buttons and switches visible, but only a few as the big screens dominate the driver’s side of the front row.

The look is helped by a series of recycled and “sustainable materials” including recycled PET and bio-based polyurethane. Kia’s aim is to “phase out the use of leather and continuously increase the use of bio-based materials”, so even the GT-Line doesn’t have real leather in it.

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.

Along with its general design, the EV3 also has the same focus on space efficiency as the much larger EV5 medium SUV and EV9 large SUV.

Kia compared the EV3 to the BYD Atto 3 and Volvo EX30 upon its global launch in Korea, and it’s stuck with the same comparison as it launches here.

In many exterior dimensions, the EV3 is smaller than the Atto 3, a medium SUV by sales category, while it’s larger than the EX30 in almost every way. However, interior dimensions are reported by Kia as being bigger than both cars in most aspects aside from the first row legroom, but even there only by about 10mm.

The EV3 is 4300mm long, 1850mm wide and 1560mm tall, and has a 2680mm wheelbase, but inside does feel like it’s a category upwards in terms of space.

Along with the roomy interior dimensions, there are plenty of handy spots to put things - a big central storage area and a higher one under the armrest, the device charger, door bottle holders - these and all the controls are generally within reach. 

The GT-Line loses a little bit of this storage space by turning the spot under the central armrest into a sliding table, which could be useful sometimes, but doesn’t seem to me as helpful as another place to put a drink, a wallet, keys, an avocado or whatever other trinkets you and your passengers may have.

The huge multimedia and driver display setup consists of two 12.3-inch screens and a 5.0-inch climate control screen in the middle. The centre climate screen is a little hidden by the steering wheel, but there are also physical climate controls also in the centre under the screen, so there’s nothing vital you can’t do in the EV3 easily.

There are also shortcuts to the main functions of the menu like navigation and media, Kia says tactile controls like that are important for keeping the car usable for a broad range of people.

In the second row, the EV3 feels pretty well suited to four adults for a reasonable trip - I’m 178cm and can sit behind my own seating position comfortably, though if I was too much taller my knees might rest on the hard plastic seat-back.

There is an armrest, places in the doors to put water bottles, and two USB-C plugs actually fitted into the seats. There’s also a little slot to put a phone that might be charging, though it could easily (and perhaps more usefully) fit other things instead.

Behind the second row is a generous 460L boot which puts other electric small SUVs to shame - the EX30’s is 318L and even the Atto 3’s is 440L. The EV3’s boot space extends to 1250L with the seats folded down.

The EV3’s boot floor can also drop down to accommodate taller items, plus there’s a 25-litre ‘frunk’ or under-bonnet storage space.

There’s no spare space-saver tyre, however, as is becoming disappointingly common.

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.

All three versions of the EV3 have the same drivetrain, the only difference being the smaller battery in the Air Standard Range.

The EV3 is front-wheel drive only, with a single motor at the front wheels putting out 150kW and 283Nm.

Differing weights between variants result in different 0-100km/h times, the quickest being the entry-grade Air Standard Range at 7.5 seconds, likely thanks to a smaller and lighter battery.

The Air Long Range takes 7.7 seconds, while the Earth and GT-Line both take 7.9 seconds.

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.

There are two battery sizes for the EV3, the 58.3kWh unit for the Air Standard Range and the 81.4kWh battery each of the Long Range variants is equipped with.

Of course, the Air Standard Range has the shortest electric driving range - 436km under WLTP testing. Its power consumption is a claimed 14.9kWh/100km.

The Air Long Range is the variant with the furthest electric driving range of the bunch, at 604km, as well as the same power consumption as the Standard Range at 14.9kWh/100km.

The Earth and GT-Line both wear the same set of figures, albeit lower distances and higher consumption than their more affordable counterparts. With 563km of electric range and 16.2kWh/100km consumption figures, they’re still able to cover very usable distances for real-world use.

Charging is the same across the line-up, with the supplied Type 2 AC charger working at a maximum 6.9kW on single phase or 10.5kW on three-phase power, and taking five hours and 20 minutes for Standard Range variants, or seven hours and 15 minutes for a Long Range from 10 per cent to 100 per cent.

On DC fast charging, with a CCS Type 2 charger, the EV3 charges as quickly as 29 minutes from 10 to 80 per cent in Standard Range, or 31 minutes in Long Range, when using a 350kW fast charger.

While we didn’t get a chance to properly run down the battery and test the EV3’s range, the drive route was relatively demanding with power consumption yet the EV3’s range didn’t plummet like you might expect on fast, steep and winding roads.

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.

The EV3’s arrival on Australian roads is not only important because it means we can test it in right-hand drive, but also because it’s had a localised ride and handling tune. Time for the proper judgement.

Kia Australia's local program lead for this is, as it has been for years, Graeme Gambold, and according to the brand he aimed for neutral balance with confidence-inspiring and responsive handling, and a linear, natural steering feel. And it’s pretty close to nailing all of that.

In town and on backroads, its ability to soak up bumps and handle rough surfaces is impressive. Not a lot of noise comes into the cabin in either case, too, a feat given the road surfaces. In fact, even with the radio off, the EV3 feels pretty well insulated from the outside, including wind noise.

It's cornering and handling is nice and predictable. It feels designed to be safe if you misjudge a corner, only gently understeering when you've come in a bit spicy.

The body doesn't roll or pitch dramatically, so the car feels planted and, as intended, flat through the bends.

But there’s one aspect to the tune in which the EV3 feels like it could do with a little more attention - its steering.

At low speeds, the steering is light enough, but at higher speed it feels a little heavy. I’m not sure if Gambold’s been going to the gym or if it’s that I haven’t really, but it feels like there’s some unnecessary resistance, regardless of drive mode or camber on the road, requiring a bit more input on the wheel than you'd like.

It does let the car down in terms of driving out on country roads, but fortunately it's not a dealbreaker on highways or in its intended city or suburban environments.

Otherwise, the EV3 is extremely pleasant, with its outputs and delivery feel about right for a small electric SUV, never feeling too slow or unruly. It doesn’t spin its wheels with too much torque, even on wet roads and when hustling out of a corner.

The paddles which allow you to adjust the intensity of the regenerative braking also mean you barely need to use the left pedal, which is a plus for increasing the available driving range.

Speaking of the left pedal, a sudden stop thanks to a surprise slow car around a blind corner went smoothly thanks to a decent set of brakes.

In all, the car is ergonomically sound from the drivers seat, with the positioning for the seat and steering wheel feeling comfortable and easy to adjust, though slightly better vision out the rear sides would be good.

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.

Kia’s seven-year, unlimited-kilometre warranty applies to the EV3, and though that was once industry-leading, it’s now being matched or overtaken by many rivals.

Roadside assistance is covered for one year but can be extended to up to eight years if serviced with an authorised Kia dealer.

Kia also backs the high-voltage equipment in the car with a more specific seven-year or 150,000km warranty, whichever comes first.

Australian servicing costs are pretty minimal in the EV3, with Kia offering well-priced pre-paid plans of three ($674), five ($1285) or seven years ($1897). Certainly some points for Kia on that one.

Service intervals are on the shorter side for an EV, at every 12 months or 15,000km, whichever comes first.

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.
