Lexus RX350 vs Lexus UX250H

What's the difference?

The RX is a big SUV that doesn't always look, or drive, like one, and – in 500h guise especially – can put a smile on a driver's face, too.

Gone are the cabin quirks and the polarising design elements (well, mostly...), and in their place you'll find a solid, premium-feeling family offering without much in the way of drawbacks.

Most cars get worse as they age as their makers try and save pennies by scrimping on quality and features. But the reverse seems to be true for the Lexus UX.

The 250h Luxury 2WD we tested is the car that the brand should have launched with back in 2018, with an appealing balance of performance and economy, comfort and sporty handling, as well as refinement and features. The UX has finally come of age.

Honestly, the Lexus RX looks far more powerful, and cohesive, in the metal than it does in some photos, and in the right colour (we're fond on the deep black or the copper-rose hues), it looks downright fetching.

That Predator-shaped front-end is massive, but the way the Spindle grille kind of bleeds in the body work at the nose of the vehicle is a neat trick, and the whole design ethos gives the RX a sportier, more modern, and more intimidating, energy from almost every angle.

Perhaps the most clever element though is the wave-like design piece that links the rear window with the boot, somehow managing to shrink almost-five-metre SUV (visually, at least), and leaving the RX looking more sporty than hulking.

The door handles are cool, too. They’re fixed, and you just touch them to open the door, with a similar system used once inside to get out again.

Inside, Lexus has gone for a clean, modern-feeling space, and, thankfully, there isn't a Remote Touch trackpad in sight. Instead, you can choose between two screen sizes – 9.8- or 14.0-inch – which kind of dominate the dash, while the air-con controls are digital and interactive, too.

It must be said, though, some interior treatments feel far more special than others, and while Lexus in Australia isn't spilling on specifics for our market just yet, the top-spec models will almost certainly feel more plush than the cheaper ones.

A hefty portion of the UX’s engineering underneath is shared with the popular Toyota C-HR. Not that you would necessarily know that by glancing at it.

Even five years on from launch, the current model looks slick and contemporary, and it seems to have informed the styling of newer, larger Lexus SUVs like the latest NX.

Not that you’d call the UX an SUV – it’s very much a higher-riding hatchback, with a ho-hum 160mm of ground clearance.

To put that in perspective, other crossovers are taller: the GLA has 213mm, while Subaru’s new Crosstrek boasts 220mm. At least the UX’s is loftier than the C-HR and its pitiful 137mm.

That said, the angular wheel arches and wide-track stance serves the Lexus well.

The entire RX range now rides on Lexus' GA-K platform, which is lighter (-40kg), more rigid, and offers a lower centre of gravity (-15mm) than the model it replaces.

The RX is wider (+25mm to 1920mm), lower (-10mm to 1695mm), but no longer (still 4890mm) than the outgoing model. But Lexus has lengthened the wheelbase (+60mm to 2850mm) to earn some extra backseat space for rear riders.

And it must be said, there is lots of room for backseat riders. Sitting behind my own 175cm driving position I had more than enough knee room, and enough head room, and a general feeling of airy spaciousness.

Elsewhere you get the usual practicality perks, with two cupholders up front, two more in the pull-down seat divider that splits the rear seat, and there are two ISOFIX attachment points in the back seat, too.

Charging is handled by a four USB ports, and depending on the trim/spec balance Lexus in Australia shoots for, you should at least find vents with temp controls for backseat riders, too.

Lexus is yet to confirm the luggage space specs for the new RX, but given it’s only being offered with five seats, and that there’s been no change to the vehicle’s length, you can expect a fair bit of room for bags in its auto-opening boot.

The UX’s compact crossover-esque hatchback proportions have implications inside. Inevitably, this is no larger than the (related) Toyota Corolla, despite having the higher seating position.

Beyond that, though, the 2023 model highlights how Lexus has made its so-called ‘gateway’ model better than before.

For starters, despite being the base grade, this UX has a properly premium ambience, backed up by exceptional fit and finish.

From a sensory perspective, the UX looks, smells, feels and sounds like a Lexus should. And by the latter, we mean the cabin is pleasingly isolated from the outside world.

The overhauled touchscreen and multimedia system is a huge step forward for the series. The larger new display looks great and works well – what a monumental improvement over the infuriatingly fiddly old set-up. It’s difficult to see how they’ll improve it. Dependable and glitch-free. Are you listening, all European manufacturers?

Meanwhile, the carryover parts that worked well enough before continue to impress.

The UX’s front seats are sumptuous in their cushy softness and comfort, yet provide sufficient support over longer driving distances.

There’s also the excellent driving position, with most switchgear within grasp. There’s just enough space for taller people to settle in nicely up front. And the basics like ventilation and storage are thoughtfully executed. The climate in the UX is always fine.

Negatives? Don’t worry, we’ve identified several.

As mentioned earlier, the now-better-equipped Luxury does have all the essentials. But for a car that’s approaching $60K-drive-away, we’d expect kerb-side mirrors that dip down when reversing to avoid damaging alloys against gutters; we couldn’t get ours to auto-fold when locking up, either.

Driver vision out isn’t great. Thick pillars and that rising shoulder line make changing lanes and reversing a technology-reliant affair, as it’s difficult to see objects that are too-easily obscured. For the same reasons, a front camera would be useful in this grade.

Others might expect a sunroof, or cooled seats that massage, or a head-up display for the instrumentation, but we’d argue that they’re hardly necessities. Lexus has to upsell buyers to something.

Moving on to the back-seat area betrays the UX’s compactness most.

The back doors have small apertures. Entry/egress is challenging for folk with long legs. Legroom is tight, and three adults abreast would be a struggle, so it’s best to treat the littlest Lexus crossover as a four-seater.

Yet headroom is fine, the appearance and finish remain first class as it is up front, and the basics are all present – air vents, grab handles, coat hooks, overhead lighting, one map pocket, centre armrest with cupholders, two USB outlets, and windows that wind all the way down. Narrow front seats aid with light, vision and ambience, too.

Further back, the luggage area is pretty petite for an SUV, though the boot is (slightly) larger than the Corolla and Mazda3’s. That powered tailgate is useful if your arms are full, but the loading lip is high.

Normal boot floor depth is shallow but most of that flooring can be removed to reveal a hidden compartment underneath.

Small side pockets are also useful. You’ll find a 240V outlet. Bag hooks and floor tie-down hooks are fitted.

And – being a hybrid – there’s no spare wheel, just a tyre inflation kit. And the flimsy cargo cover is there only to keep prying eyes out.

Not big on utility, then, but the UX is true to its role as a Lexus in concentrate form.

Let’s list those changes briefly, as they inform the car you see before you.

The pre-facelift UX released in 2018 was criticised for riding too harshly and not being fun enough to drive.

So, Lexus says the MY23 version’s steering rack is better braced, the suspension and rear adaptive dampers have been retuned, the chassis gains more spot welds for added rigidity and the body is now stiffer and stronger than before. These are learnings directly applied from the UX300e EV version released in late 2021.

Most buyers will probably be more impressed with a now two-inch larger touchscreen, updated and (at long last!) easier-to-operate multimedia system, post-crash emergency services-callout should the driver end up incapacitated, upgraded voice recognition system, more-effective lane-keep assistance, improved traction through corners, better surround-view monitor and jazzed-up trim presentation.

Collectively, they strive to finally bring the expected/demanded on-brand qualities lacking from the previous model and in the UX’s largely-patchy competitor set – namely the Audi Q2, BMW X2, Jaguar E-Pace, Mercedes-Benz GLA and Volvo XC40. 

This is especially so when sizing up the entry-level front-wheel drive grades (euphemistically dubbed 2WD at these exalted heights) of each, as we have done with the least-expensive hybrid version of the UX, the 250h Luxury from $53,820 (all prices are before on-road costs).

Costing nearly $8000 more than the base 200 Luxury petrol version, the hybrid accounts for the lion’s share of sales, and really has no direct electrified premium rival at that price point, except in the recently-released Alfa Romeo Tonale Ti from $49,900 – though that’s a mild-hybrid set-up with a 48-volt battery.

Along with an electric motor and a small Nickel-metal Hydride (Ni-MH) battery, the 250h Luxury is compellingly equipped for a base grade, including a 12.3-inch touchscreen, wireless Apple CarPlay, wired Android Auto, Bluetooth telephony, ‘Hey, Lexus!’ voice recognition, 10-speaker audio, digital radio, satellite navigation, remote engine-start/door-unlocking/hazard flashers/buzzer, acoustic windscreen glass, heated/powered mirrors, powered steering column, heated/powered front seats, climate control, keyless entry/start, a powered tailgate, roof rails, alarm and 17-inch alloys.

The 250h Luxury also comes with ‘Enhancement Pack 2’, featuring a powered tailgate with kick sensor, a wireless phone charger, cornering lights, headlight cleaners and rear privacy glass.

On the safety front, there’s all the usual driver-assist tech equipment including Autonomous Emergency Braking (AEB), lane-support systems and rear-cross traffic alert, amongst other items. Check our safety section for a full rundown.

So, yes, the UX 250h Luxury represents strong value. Even for a luxury-branded vehicle.

Let’s start with what we’re not getting at launch. Internationally, there's a new plug-in hybrid variant that pairs a 227kW hybrid system with a 18.1kWh lithium-ion battery for an EV driving range of more than 65kms, but fight though Lexus in Australia did, it couldn't secure the model for our market at launch. It wants it though, and badly. So watch this space. 

Instead we get three options, including the RX 350h, which pairs a 2.5-litre petrol engine with Lexus' existing hybrid system to produce a total 180kW and 316Nm. It's paired with a constantly variable transmission and will be offered in two- or all-wheel drive.

There’s also a turbocharged 2.4-litre petrol engine on offer in the RX 350, good for 205kW and 430Nm, and paired with an eight speed automatic and AWD.

But the powertrain I really, really like lives in the RX 500h F Performance, and pairs a 2.4-litre turbocharged petrol engine with an electric motor up front, and a second at the rear axle, for a total of 273kW and 551Nm.

The all-new hybrid system has been designed with turbocharged engines in mind, and features a single electric motor at the front, and a bigger rear motor, with the latter able to provide real driving power to the rear tyres - and contribute to a sprint to 100km/h of just 5.9secs.

Lexus calls it an 'eAxle' motor, and it can deliver some 76kW to the rear tyres. It pairs with a 'DIRECT4' all-wheel drive system which the brand says improves "handling, controllability, and feel."

Fitting, then, that it features on the RX 500h F Performance, which also introduces a new go-fast tier for the Lexus brand (though one you can expect to see more frequently in the near future), and which sits between the existing F Sport and the top-tier, full-fat F models.

The brand says things like bigger brakes, performance components and the highest power outputs will be reserved for the F Performance models. And so it is with the RX 500h F Performance, which welcomes six-piston front brakes, adaptive variable suspension, dynamic rear steering and 21-inch wheels.

The UX’s Corolla/C-HR connection continues with its 2.0-litre (1987cc) twin-cam four-cylinder petrol engine, delivering 107kW of power at 6000rpm and 188Nm of torque between 4400 and 5200rpm.

The 250h Luxury pairs that with an 80kW/202Nm permanent magnet motor and 1.4kWh Ni-MH battery, for a combined power output of 135kW. A second, rear-mounted motor is available in higher grades, providing all-wheel drive. But not in this Luxury guise.

As with most Toyota and Lexus hybrids, charging is only via the petrol engine and recuperated energy from braking. Electric-only drive is only offered during brief spells of low-speed light-throttle driving, or off-throttle coasting where conditions allow.

Drive is sent to the front wheels via an electronically-controlled continuously variable transmission (CVT). Three modes are offered – 'Eco', 'Normal' and 'Sport'.

Tipping the scales at 1625kg (kerb), the 250h Luxury offers a power-to-weight ratio of nearly 83.1kW per tonne. That’s a hefty output for a hybrid. Top speed is 177km/h, with 0-100km/h needing 8.5 seconds.

Underpinning that performance is a MacPherson-style strut-front and a multi-link rear suspension set-up.

Let’s start with the pure-petrol RX 350, which will sip a claimed 8.8 litres per hundred kilometres on the combined cycle, and will demand premium petrol. The RX 350h is more fuel efficient, demanding 6.4 to 6.7 litres per hundred kilometres on the combined cycle.

But the most impressive is the RX 500h, which Lexus says will need 8.2 to 8.5 litres per hundred kilometres — making it more efficient than the petrol-powered RX 350, despite producing an extra 68 kilowatts of power and 121 newton metres of torque.

Officially, the 250h averages an impressive 4.5 litres per 100km on the combined cycle, which is just 103 grams per kilometre of carbon-dioxide emissions.

Now, out in the real world, with plenty of inner-city and urban driving as well as a spell of fast highway runs punctuated by some very heavy-footed acceleration, we managed just under 7.4L/100km pump-to-pump.

That’s not too bad given how hard our UX was caned. The trip meter showed 5.6L/100km over the same distance (nearly 400km).

This is one Lexus hybrid that will happily sip from the standard 91 RON unleaded petrol pump. With a fuel tank capacity of a smallish 43 litres, expect a range of between 930km and 1000km.

For a luxury small crossover, these are economical figures.

Right, let’s cut to the chase here. I like the way the all-new RX family drives, pretty much across the board. If that’s all the information you want or need, feel free to check out here and move on to the next sub-heading.

Still here? Ok, then let’s go a little deeper.

None of the powertrains on offer feel under-powered in the RX range, which is a good start, but they all do their jobs a little differently. 

The RX 350 is probably the most familiar, with a traditional automatic and that well-known petrol-powered punch. It’s not the most powerful engine on offer here, but it’s more than enough to get the RX up and moving — but, for mine, it can feel a little thrashy (or like it’s straining a little too hard), when you really start to push it, but such is the price you pay for a four-cylinder engine pushing a large SUV.

Next up is the RX 350h, which Lexus reckons will be the best-selling model in Australia. Lexus and Toyota have been doing hybrid powertrains for some time now, and the system fitted to the new RX is predictably solid-feeling, though it too has its drawbacks – namely that the constantly variable transmission can drone on and on under constant acceleration, and even the commendably insulated cabin can’t block it out completely.

So if this is a Goldilocks’ scenario, then the just right has to be the RX 500h, which blends its powerful powertrain with a traditional-feeling automatic to deliver plenty of performance and a tight, engaging drive experience that makes it feel as though the big SUV is somehow shrinking around you from behind the wheel, courtesy of the best performance kit (brakes, adaptive suspension, etc).

But to be honest, no matter the RX, the thing that really stands out here is its on-road dynamics. The car doesn’t really wobble about, there’s not much in the way of body roll, and it feels tight and confidence inspiring, no matter the model - but especially the rear-wheel-steering equipped 500h.

The RX also does a commendable job of locking the outside world outside of the cabin. Where you want it to be a calm and sedate family hauler, it can be that. But it can also put a smile on your face on the right road, too.

And that, I think, is something to be celebrated. And also not something we’ve come to associate with Lexus over the years. But that’s now beginning to change. Long live F Sport Performance, then.

Before driving the 2023 UX250h hybrid, there was some trepidation.

All versions of the original series from 2018 were tested previously, and in every one bar the base 200 on small wheels and tyres, none lived up to the promise of a premium Lexus crossover. A harsh ride, excessive noise intrusion and dull handling made this model a disappointment.

That’s all in the past, thankfully, thanks to a sustained program to save the UX from mediocrity. The company really got the basics wrong the first time around with the horrid CT200h predecessor back in 2011, so we imagine that it would be damned if this was going down the same sorry path again.

In the 250h Luxury, as reviewed here, it is difficult to objectively fault the way everything works and drives.

Let’s start with performance. Even in Normal or Eco mode, the UX steps off the line briskly, and initially at least, it’s the electric motor and battery that silently whooshes the car forward.

If you’re gentle, you can reach speeds of up to about 40km/h before the petrol engine chimes in unobtrusively.

Beyond that, there’s a stream of electric power you can feel, keeping the acceleration coming on strong, even as speeds rise above 100km/h.

This is also true for Sport mode, except that it all happens a bit quicker and earlier, and with extra urge.

And the welcome news here is that the CVT doesn’t really make the engine sound too droney, unless the driver is mashing the pedal to the metal.

Travelling along at normal urban speeds, there’s a seamless transition from electric-enhanced petrol propulsion back to electric-only if the conditions are right – such as when coasting off-throttle.

This is most common in heavier traffic, and the resulting smoothness and quietness adds to a refined and relaxed experience.

About our only objection is when you apply the brakes. In our test car, they felt a little on/off, like a switch. At times, they seemed too grabby for smooth stopping.

That said, the driver can downshift using the gear lever to provide powertrain braking, to help minimise snatchiness.

Road noise seems to be more muted than before, supporting Lexus’ claims that retuning the suspension and beefing up the structure/chassis has helped with refinement.

We wouldn’t say the UX is at the top of the class for quietness, especially on Australia’s coarse-bitumen highways, but now things have hushed sufficiently enough for a crossover purporting to be a premium.

Where the suspension changes really transform the UX, at least on the 215/60R17 tyres the Luxury wears, is how much softer and comfier the ride is.

Where before there was suddenness there’s now suppleness, substantially improving the experience. We wonder whether the bigger-wheeled rubber the richer grades receive are as well-resolved.

As the 250h Luxury is not trying to be a hot hatch, the resulting body lean through fast corners is a happy trade-off, though it’s not so roly-poly that handling composure is adversely affected.

Plus, the steering – while light and easy at parking speeds – still offers enough response and feedback for most drivers to enjoy taking the UX for a cross-country blast once in a while.

To that end, the steering’s weighting does increase in Sport mode… though you won’t be selling your Peugeot 205 GTi for one just yet, but that previous dullness is history. In fact, whether behind the wheel or ensconced in one of the inviting outboard seats, the UX250h as a whole is a much sunnier experience all-round than before.

Tested in 2019, the UX has managed an ANCAP crash-test rating of a maximum five stars. The rating applies to all models built from October, 2020, onwards.

That’s no surprise, given the level of standard safety equipment fitted, even to this entry-level 250h Luxury grade.

You’ll find eight airbags – dual front, side chest, side head and driver and passenger knee – as well as Lexus’ ‘Pre-collision safety system’ with AEB for pedestrian (day/night) and cyclist (day) detection and daytime intersection assistance.

The AEB functions from 10km/h to 180km/h and the lane support systems between 50km/h and 180km/h.

Also included is lane-keep assist, speed-sign recognition, rear cross-traffic alert, parking support braking, blind-spot monitor, emergency steering assist, auto high beam, full stop/go adaptive cruise control and front and rear parking sensors.

Anti-lock brakes with brake assist and electronic brake-force distribution, traction control, stability control, active cornering assist, four-wheel disc brakes and a reverse camera are fitted.

Lexus’ Connected Services offers SOS emergency call, stolen vehicle tracker and other GPS-based assistance features.

The outboard rear seats include ISOFIX child restraint anchors and there are three top tethers for baby capsule/child seat straps across the second row.

The Lexus family is covered by a five-year, unlimited-kilometre warranty, which is about bang-on in the premium-vehicle space. 

While servicing details are yet to be confirmed, the previous RX required a trip to the service centre every 12 months or 15,000kms, and it will fall under the brand’s capped-price servicing program, and the Lexus Encore program, which offers all sorts of perks to owners.

Lexus offers a five-year/unlimited kilometre warranty and roadside assistance.

Service intervals are at 12 months or 15,000km.

The first three scheduled services are capped at $495 each, with the work carried out detailed online.
