Lexus NX450H+ vs Lexus UX300E

What's the difference?

The NX 450h+ Luxury combines high build quality and upmarket looks with plug-in hybrid convenience/performance/economy and numerous luxury appointments. It’s a competent all-rounder that's difficult to fault and clearly meets the needs of many prestige mid-size SUV buyers.

The Lexus UX300e Sports Luxury nails the luxury and standard features list! It certainly feels like a premium SUV inside and the updated technology and driving range were sorely needed to keep this competitive, but once you start looking at its rivals, which all offer similar specs and better driving ranges, the price point starts to feel a smidge high. However, the ongoing costs and the complimentary bonuses that Lexus throws in, are great.

The exterior is a sculptured blend of sharp creases and flowing curves which create a sporty and sophisticated appearance that clearly appeals to many buyers.

The interior looks and feels about as spacious and airy as you could realistically expect in a mid-sized SUV, which is enhanced with the roof open and sunshine pouring in.

The boldly contrasting two-tone grey and camel interior trim in our test vehicle adds to its visual appeal although we suspect such a bold colour choice could also be a stain magnet in everyday use, particularly for young families with lots of sticky kids’ stuff onboard.

The design hasn’t seen much change and Lexus seems to be encouraging an understated EV design as it looks just like its fuel-based siblings.

I don’t mind that it’s not as futuristic as some of its competitors and that, at first glance, there isn’t anything to set it apart.

The front sports a classic Lexus 'spindle' grille and the external lights are large but the rear side lights jut out rather severely, reminding me too much of its Toyota counterparts.

The rear features a cool LED strip light for the brakes, which elevates its night-time presence.

The sporty-looking 18-inch alloy wheels are a nice touch but the plastic mouldings around the base of the car detract from the premium-level this model sits in. It’s not as slick-looking as it could be.

Having said that, the interior earns back points courtesy of its premium feel with leather-accented trims and Japanese Washi paper influenced accent panels. But there is a lot happening with the dashboard.

It’s a little overwhelming at first because it protrudes well into the cabin and features multiple cutaways, but you get used to it after a while.

There are also little knobs on either side of the instrument panel that look out of place to me and resemble horns.

Its compact dimensions of 4660mm length, 1865mm width and 1660mm height make the usual driving chores in congested urban settings, particularly tight inner-city streets and parking spaces, much easier than a full-size SUV.

With its 2050kg kerb weight and 2540kg GVM, it has a load capacity of 490kg of which up to 75kg can be carried on the roof rails using approved racks.

While almost half a tonne of load capacity may seem ample, keep in mind that the combined weight of five large adults could reach that limit before you could start loading their luggage.

It’s also rated to tow up to 1000kg of braked trailer, which would be ideal for hauling small trailers with a recreational focus like fold-out campers, jet-skis, trail bikes etc. However, Lexus does not publish a GCM figure, so for weekend escapees we don’t know how much it can legally carry and tow at the same time.

There’s more than adequate space for the driver and front passenger, along with storage that includes a bottle-holder and bin in each door, overhead glasses holder and a single glove box.

The centre console has two cupholders and a deep box with padded lid that doubles as a comfy elbow rest. You’ll also find a quartet of USB ports, a 12V socket and wireless phone charging pad.

The rear bench seat is surprisingly accommodating for tall people, given I’m 186cm and when seated behind the driver’s seat set in my position I still have sufficient knee clearance and headroom.

However, with three up, those in the centre must compete for shoulder space plus have their feet either side of the transmission tunnel and knees together between the front seat backrests. So, three adults is okay for short trips but should be capped at two for longer drives.

Rear passenger storage includes a bottle-holder and bin in each door, pockets on both front seat backrests and two cupholders with the centre seat backrest folded forward. The rear of the centre console has adjustable air vents, rear seat heating controls, another 12V socket and a pair of USB ports.

The power tailgate can open by waving your foot under the rear bumper (useful when hands are full) to gain access to the rear luggage area, which provides numerous internal hooks for securing cargo straps or nets plus underfloor storage for the charging cables and more.

This luggage area offers up to 520 litres (more than half a cubic metre) of load volume with the rear seat upright. It expands into what is effectively a small van when the rear seat is folded flat, which can carry everything from a mountain bike to flatpack furniture.

As soon as you slide in, you’re reminded that the UX is a small SUV. Even with the driver's seat at its lowest position I still knock my knees on the steering wheel when getting in and out of the car.

The higher door sills also accentuate the penned in feeling despite there being plenty of head- and legroom in the front row! 

Then comes the back seat, which is super tight on space. I’m 168cm (5'6") and my headroom is fine but the legroom sucks. My knees press into the back of the driver’s seat (set for my driving position).

There’s also not a lot of space underneath the seat for toes, so I wouldn’t recommend the UX to anyone who regularly transports tall passengers. 

Having said that the seats in both rows are very comfortable and the leather trims feel lovely to touch. Both front seats are electric with heat and ventilation functions but only the driver’s side enjoys adjustable lumbar support. 

Storage is good throughout the car, which is not usually the case for the small SUV class. Up front you get a glove box, two cupholders, two drink bottle holders and a middle console that opens from both sides, which is handy and cool.

In the rear you get two cupholders in a fold-down armrest and map pockets but no storage bins in either door unfortunately.

Other amenities in the back are very good for this class with the heated outboard seats, directional air vents, reading lights and two USB-C ports.  

On that note, the upgraded multimedia system is now easier to use while on the go, is responsive to touch and looks great.

Some of the information on the system can be annoying to find but the customisations available on the 7.0-inch digital instrument panel more than make up for it.

There is a coloured head-up display, wireless Apple CarPlay, wired Android Auto and satellite navigation.

All are easy to use and won’t confuse you too much!

The charging options are great with each row getting two USB-C ports but the front also gets a USB-A port, 12-volt socket and a wireless charging pad. You’re seriously spoilt for choice.  

The boot space sits at a small 314L, which is 100L less than the previous model but that’s because Lexus has made a little storage nook underneath the floor for the tyre repair kit and cable pouches.

It's a great boot because it sits high and is easy to access, and I have plenty of room for all of the gear needed for a week’s errands. The hands-free powered tailgate is great, too.

There are only two variants for the electric UX and our test model is the top-spec Sports Luxury but the gear isn’t the only thing that’s been upgraded. The before on-road costs price for this model has jumped by almost $7K to a hefty $87,665!

In comparison, the BMW is the nearest rival at $84,900 (MSRP) and the Mercedes-Benz is a bit more affordable again at $82,300 (MSRP) while the Volvo sits pretty at $76,990 (MSRP).

The UX300e is the most expensive but is well-specified by anyone’s standards.

The Sports Luxury grade maintains its premium features, like the sunroof, heated front and rear outboard seats, ventilated front seats, and a heated steering wheel.

But the technology has been retooled and a new 12.3-inch touchscreen multimedia system replaces the previous model's 10.3-inch touchpad arrangement. It’s a welcome addition as it’s much easier to use.

New features, like wireless Apple CarPlay, acoustic front glass and insulation around the bonnet and wheel wells provide additional on-road comfort and practicality.

Lexus also throws in an AC Type 2 charging cable, as well as a GPO (General Power Outlet) cable. The technology is robust but I’ll go into more detail in the Practicality section.

Other standard features are solid with 18-inch alloy wheels, a tyre repair kit, handsfree powered tailgate, full suite of LED exterior lights, 10-way electric driver’s seat and an eight-way electric front passenger seat (but only the driver enjoys adjustable lumbar support).

The leather-accented trims feel luxy and the steering wheel has mounted controls and paddles to customise the regenerative braking while on the go.

The sophisticated PHEV drivetrain with electronic AWD comprises a 2.5-litre four-cylinder petrol engine that delivers 136kW of power and 227Nm of torque to the front wheels through a Continuously Variable Transmission (CVT).

There’s also electric motors front and rear, fed by an 18.1kWh lithium-ion traction battery that can provide limited electric-only driving range.

The front electric motor, which assists with driving the front wheels through the CVT, produces 134kW/270Nm while a smaller one exclusively drives the rear wheels with 40kW/121Nm. Although the combined output from these three power sources is 310kW, Lexus claims a total system output of only 227kW to optimise efficiency and reliability.

The petrol engine and electric motor outputs are electronically synchronised and traction is continuously monitored to automatically vary the amount of power being sent to the front or rear wheels to optimise stability and traction in all conditions.

There’s also a choice of drive modes comprising 'Normal', 'Sport' and 'Eco' and paddles on the steering wheel allow manual shifting of the CVT 'ratios' for a more engaging drive, or to increase the regenerative braking effect (like using lower ratios on descents etc).

Several operational modes can also be selected including electric-only driving (we covered 60km on one full charge and 56km on another) and two modes of hybrid driving, plus battery charging while driving courtesy of the petrol engine which during our test charged the battery from near zero to 100 per cent in 56km.

There’s also external plug-in charging of course. At home we used the three-pin domestic wall socket compatible 10A charger/AC Type 2 cable supplied with the vehicle, which took about six hours (at a tiny 2.3kW) to charge from 35-100 per cent.

The UX300e has a fully electric powertrain with a 72.8kWh lithium-ion battery that’s located on the front axle.

The power and torque remain unchanged at 150kW and 300Nm but that’s enough to produce a 0-100km/h sprint time of 7.5-seconds. Plenty of oomph for city-slickers and open-roaders to boot.

The update sees the battery increase in capacity by 34 per cent which means the driving range has jumped from 305km to 440km.

That's still a bit lower than some of the UX's competitors but it certainly helps ease range anxiety! And unlike some of its rivals, the UX300e only sports a front-wheel drive drivetrain.

Lexus claims average combined consumption of only 1.3L/100km, achieved in ideal lab conditions which is largely irrelevant. When we stopped to refuel after 424km of real-world testing, which included our usual mix of suburban, city and highway driving and switching between the different modes (including 116km of electric-only driving), the dash display was showing 5.7L/100km.

That was close to our own figure of 5.4 calculated from fuel bowser and tripmeter readings, so based on our test consumption and depending on the mix of drive modes used, you could expect a realistic driving range of up to 1000km from its 55-litre tank which prefers 95RON premium petrol.

My energy consumption sat at an average of 19.5kWh, which is decent considering all of the open-road driving I did.

There are four levels of regenerative braking to help conserve battery percentage but even on the firmest setting, it’s not super noticeable.

When you’re at full charge, multiple notifications and sound alerts pop up on the instrument panel stating ‘Regenerative Braking Limited Press Brake to Decelerate’. It’s quite an intrusive feature but disappears after 20 to 30km.

Despite the bigger battery size, the UX300e can only accept up to 6.6kW on AC charging, whereas, all of its rivals can accept 11kW. On a 240-volt AC charger, expect to see a charge time of nine and a half hours to get to 80 per cent.

Curiously, the UX features two charging ports, on the right-hand-side, there is a Type 2 port and, on the left, a CHAdeMo port, which allows for faster charging.

You'd think it would be easier to simply add the CCS enhancement on the Type 2 port but still, expect to get from 10-80 per cent in 80-minutes on a 50kW fast charger.

The cabin is what you might call ‘cosy’ for tall people like me (186cm) but there’s still adequate room to find a comfortable driving position.

The ride quality is noticeably firm, which contributes to its sporty feel. The steering is nicely weighted with good response and braking is reassuringly strong.

Acceleration in full-electric and hybrid modes is brisk but not exceptional and about what you’d expect from this powertrain, which engages the rear electric motor for standing starts and other situations to ensure all-wheel drive traction is being deployed when you need it most.

We sampled the different drive modes, with 'Sport' providing a more engaging feel (particularly when manual shifting using the paddle shifters), 'Eco' producing a more subdued response to optimise range and the default 'Normal' providing a pleasant compromise.

Even so, despite its technical wizardry and generous choice of driver preferences, we reckon most daily driving owners would simply plug-in and charge each night, start off in electric-only mode and if needed continue in ‘Normal’ hybrid mode.

The UX300e comes into its own when you’re zipping around tight city streets. The power is responsive and the steering crisp with excellent cornering capabilities.

It feels well-placed on the road most of the time but can move around when it gets hit by high winds.

While the power is steady, the tyres can lose a little traction if you’re too quick to accelerate from a full stop.

The ride comfort is also very good with the new acoustic glass and extra insulation around the bonnet and wheel wells providing a whisper quiet cabin space.

The suspension is well-cushioned but not floaty and you won’t wince when you hit a bump, but occasionally you get a thump-thump shudder through the frame on certain rough road surfaces.

It’s not a massive size and you’ll be thankful for that when it comes time to park because it is seriously easy to slide into a spot!

The 360-degree view camera system is top-notch providing clear graphics and a cool feature where the car becomes invisible in the video feed, which makes it even easier to see all around you. Coupled with the front and rear parking sensors, you’re set.

The UX300e has a bunch of great safety features that come as standard and I like the proximity alert that pops up a camera feed of your surroundings when you’re in stop/start traffic. It’s a practical feature to help identify pedestrians or cyclists in your blind spots.

Other standard safety equipment includes forward collision warning, blind-spot monitoring, daytime running lights, rear cross-traffic alert, lane keeping aids, lane departure warning, adaptive cruise control, intelligent seat belt reminders, traffic sign recognition, an SOS call button, and that awesome 360-degree view camera system.

Family-friendly features include two ISOFIX child seat mounts on the rear outboard seats plus three top-tethers but two seats will fit best.

The UX also has a rear occupant alert if it detects weight or seat belts in use in the back seat, which is always a great feature.

The UX has a maximum five-star ANCAP safety rating from testing done in 2019. It also has eight airbags, which includes knee airbags for both front occupants.

Comes standard with a five years/unlimited km warranty. Same applies to the lithium-ion traction battery, which is eligible for additional warranty coverage of up to five years (so 10 years in total) based on annual inspections.

Scheduled servicing is every 12 months/15,000km, whichever occurs first. Capped pricing, which applies to the first five scheduled services up to five years/75,000km, totals $3225 or an average of $645 per service.

The UX comes with a five-year/unlimited km warranty but the battery is covered by a 10-year or up to 160,000km warranty, which is better than most in this class.

This also comes with a five-year capped-priced servicing plan where services cost a flat $295, which is good but the servicing intervals are more in line with a fuel-based car at every 12-months or 15,000km, whichever occurs first. It’s typical to see intervals stretched out at every two years for an EV.

Lexus also throws in a few sweeteners for owners with three-year complimentary subscriptions to both ChargeFox and Lexus Connected Services, as well as, installation of an at-home wall charger. It’s not often you see the word ‘complimentary’ coupled with a luxury brand, so that’s a nice touch.
