BMW X5 vs Lexus NX450H+

What's the difference?

This is a luxurious prestige five-seater brimming with BMW’s latest design and technology that’s not only practical for weekly family duties but can also embrace spirited driving with the push of a button. A great all-rounder for families that like a sporty edge. 

The Lexus NX450h+ F Sport is a gorgeous mid-size SUV that combines great specs and a fairly efficient plug-in hybrid powertrain. It’s a comfortable and easy ride which should appeal to a wide range of driving styles. It also looks good parked at the kerbside of a city street and with it ticking most of the boxes, it may become your new best friend.

The latest front-end design features subtle revisions to BMW’s signature 'kidney' grille theme, highlighted by slimmer matrix LED headlights with chevron-shaped DRLs that incorporate the turn indicators.

There’s also an ‘iconic glow’ function, which illuminates the twin-grilles at night in-sync with the external courtesy lights when approaching and departing the vehicle. Lower front air-intake and tail-light treatments have also been revised.

The dash features a new curved instrument panel. Based on BMW’s latest generation 'iDrive' operating system, it consists of a 12.3-inch driver’s info display and 14.9-inch control display presented across the same seamless glass surface.

The control display’s touchscreen functionality has allowed dash buttons and switches to be minimised.

This new design dash has a blend of synthetic leather trim and dark brown/high-gloss woodgrain surfaces, along with new LED ambient lighting and gear-selector design.

The rear seat is sumptuous and spacious, even for someone my height (186cm). There’s ample knee and headroom and it can seat three kids in comfort, but for adult passengers wanting that 'business class' feel it would be ideal for two.

My only criticism of the new instrument display is that with more than 30 applications displayed on the expansive control screen, it can be distracting at times trying to visually locate and operate these functions while driving.

And, depending on sun angle, there were also complaints from different front seat passengers on different days about blinding glare caused by the dash’s high-gloss woodgrain inserts. Fortunately, the driver is unaffected by these reflections.

The NX simple looks like a scaled-down version of its larger RX cousin, so if you like that you’ll like what the NX.

It looks sweeter, though, with its smaller proportions being only 4660mm long and 1670mm high but there’s enough sharp pleating in the panelling and rear LED lights to give it a sporty edge. It’s a design that should appeal to a wide range of people.

The interior helps the NX compete against some of its flashier rivals, but the BMW X3's interior beats it hands down with the wow factor. Still, the dual-toned leather upholstery and fabrics of our test model scream understated luxury.

The perforated leather of the seats is supple underhand, but even the robust synthetic leather on the backs of the seats and some door panelling feels like the real stuff most of the time.

The dashboard components – like the air vents, displays and accents – are well integrated and seem well-built. The cockpit is intimate and plush overall, and it always reminds you that you're in the cabin of a luxury vehicle.

With its 2165kg kerb weight and maximum allowable weight of 2885kg, our test vehicle can legally carry up to 720kg.

That should be ample for five adults (even better for kids) and their luggage, of which up to 100kg can be carried on the roof rails using a rack or roof box (both in BMW's accessory range).

Powered upper and lower tailgates provide good access to the luggage area, which is carpeted and equipped with a roll-out privacy screen, load securing hooks, a 12-volt accessory outlet and a first-aid kit stored behind a removable side panel.

The space-saver spare and tools are stored below the hinged load floor, so all luggage must be removed to access them.

Internal luggage space with the rear seat upright is 650 litres (0.65 cubic metres) which expands to 1870 litres (1.87 cubic metres) with the rear seat folded flat.

A useful load-carrying feature when the rear seat’s backrest is upright is a hinged centre section that folds forward and flat to carry long and narrow items.

These can stretch all the way from the tailgate to the dash if need be, which could be handy for carting anything from skis to home hardware purchases (firmly secured, of course).

It’s also rated to tow up to an impressive 3500kg of braked trailer, which matches the class benchmark for one-tonne utes.

However, given that tow-ball download (TBD) is usually around 10 per cent of trailer weight, the X5’s maximum TBD rating of only 140kg could be a challenge if 3500kg towing is required.

Front of cabin storage includes a big bottle-holder and bin in each front door, a glove box and on the right-hand side of the dash a pull-out driver’s bin, both of which are felt-lined.

The centre console, in addition to its wireless phone-charging pad, USB-A port and 12-volt outlet, has two small-bottle/cupholders up front and a large box at the rear, housing a USB-C port and topped by a padded dual 'brochure fold' lid that double as an elbow-rest for driver and front passenger.

Rear seat storage includes a large-bottle holder and bin in each door and pockets on each front seat backrest. The rear of the centre console has two storage nooks for small items in addition to its air-vents, two USB-C ports and a 12-volt outlet. There’s also a handy tablet-mount and USB-C port on each front seat backrest, which is great for long trips.

Folding down the rear seat’s centre armrest reveals two pop-out small-bottle/cupholders. And under its hinged lid is a hidden felt-lined compartment that’s ideal for storing slim screened devices away from prying eyes.

The cabin of the NX is spacious where it needs to be for four adults to be comfortable on a longer journey, and features enough equipment to satisfy most.

Access is best at the front because of the wider door apertures and while still easy enough to get in and out of from the back, the rear wheel arch cuts into the aperture a bit.

The front seats are very comfortable with thick padding, tall side bolsters that lock you into place in a turn as well as heating and cooling functions.

The back seats are almost as comfortable as the front! However, the outboard seats offer the best under-thigh support. It is a shame that they miss out on heat functions for its grade level, though.

Storage is fairly good for the class, with lots of small item cubbies up front like a sunglasses holder, a mini drawer next to the drivers' knee and a dedicated phone holder and two cupholders. The large glove box (that can hold more than just a manual) and mid-size middle console shoulder most of the storage burden, though.

In the back you get a couple of map pockets, small storage bins and two cupholders. which is most than enough for this size of SUV.

The boot offers an impressive 520L of capacity and a level loading space makes it an easy car to slide larger gear in and out of. The little storage compartment under the floor is handy for charging cables and the hands-free powered tailgate is always handy to have.

The technology is a nice mix of easy-to-use and high-end with a responsive touchscreen on the 14-inch multimedia display. The system has built-in sat nav, wireless Apple CarPlay and Android Auto. The CarPlay was simple to set up and has maintained a steady connection with my iPhone this week.

Charging options are decent with two USB-C ports and a 12-volt socket per row, as well as a wireless charging pad up front.

With a price hike of almost $6K, our flagship NX sits at $95,900 before on-road costs, but it's still slightly more affordable than its top-grade plug-in hybrid rivals.

The Volvo XC60 Ultra is priced from $101,390 and the outgoing BMW X3 xDrive30e sits at $102,500.

In the flagship variant, the standard features list is well-rounded to include both practical and luxury equipment. There are electric front seats with heating and cooling, an F Sport steering wheel with heating and touch controls, a sunroof, rear privacy glass, and a power-adjustable steering column.

Other items include a powered tailgate with a kick-to-open function, dual-zone climate control with a humidity sensor, parking assist, keyless entry/start, a digital key, Lexus Connected services app, a digital rearview mirror and 20-inch alloy wheels.

The technology looks gorgeous with the 14-inch touchscreen multimedia display taking centre stage with built-in satellite navigation, Bluetooth and wireless Apple CarPlay and Android Auto.

You also get a 10-speaker Lexus premium sound system, which has AM/FM radio, MP3 and WMA (Windows Media Audio) compatibility. There are four USB-C ports (2/2), a 12-volt socket and a wireless charging pad.

So while our test model misses out on some of the items you might expect to see for a top-model grade – like three-zone climate control and heated rear outboard seats – it still feels well-specified.

The X5 xDrive40i is powered by BMW’s legendary 3.0-litre DOHC 24-valve in-line six with state-of-the-art technology.

This includes twin-scroll turbocharging, variable valve/camshaft timing and 48-volt mild hybrid technology (delivering up to 9.0kW and 200Nm) using an electric motor integrated with the transmission.

The combined effect is optimised power and throttle response (0-100km/h in 5.4 secs) with minimal fuel consumption and Euro 6d emissions.

It produces 280kW between 5200-6250rpm and 520Nm of torque (this can reach 540Nm with hybrid input) across a remarkably wide and flat peak torque band between 1850-5000rpm, which showcases its flexibility. There’s also auto start-stop and selectable drive modes.

This is paired with BMW’s smooth and sharp-shifting eight-speed torque converter automatic, which combines the best characteristics of a dual-clutch and traditional torque converter transmission.

There’s overdrive on the seventh and eighth gears to optimise fuel economy and the choice of rapid manual-shifting using the steering wheel paddles.

Power reaches its wide tyres through the xDrive intelligent all-wheel drive system, which actively varies the engine’s torque distribution between the front and rear wheels to optimise traction at all times.

BMW’s ‘Efficient Dynamics’ also includes brake energy regeneration with recuperation display and many other standard features to enhance driving safety and efficiency.

The NX450h+ F Sport is the first attempt at a plug-in hybrid powertrain for Lexus. It pairs a 2.5-litre four-cylinder petrol engine with two electric motors, one located at each end of the car for all-wheel drive. Together they produce up to 227kW of power, but Lexus doesn’t quote the combined torque figure (cheeky).

The flagship model can do a 0-100km/h sprint in 6.3 seconds and features a smooth continuously variable transmission.

Overall, it moves quickly and the shift between the electric and engine components is barely noticeable.

BMW claims combined average (WLTP) fuel consumption of 9.9-8.5L/100km. Our 415km test comprised a mix of suburban and highway driving and when we stopped to refuel the dash display was showing 10.2L/100km which was line-ball with our own 10.6L/100km figure, calculated from fuel bowser and tripmeter readings.

So, based on our figures, you could expect a realistic driving range of around 780km from its 83-litre tank using standard 91-octane petrol.

The flagship NX has a smallish 18.1kWh lithium-ion battery and a Type 2 charging port but no CCS enhancement, which means you can’t hook it up to a fast DC charger.

On a standard AC 240-volt domestic plug port, you can charge this from 0-100% in around 7hrs 30mins. You get a great electric-only NEDC-rated driving range of up to 87km and that means you really only have to charge it every other day, which I appreciated. 

The official combined fuel cycle usage is 1.3L/100km, but you won’t really see that in the real world. After doing some longer trips mixed in with city slicking, my average real-world usage popped out at 6.5L/100km, and I averaged 20.2kWh/100km when in pure EV mode. They’re not the best hybrid figures I’ve seen for the class, but they're not too bad either.

It’s supremely comfortable, with front bucket seats that offer powered-adjustment of height, reach and backrest angle along with side bolsters that can tighten their grip of your upper torso.

There’s also two-way lumbar support, that adjusts not only how far it pushes your spine forward but also allows that pressure point to be raised or lowered.

Combined with its power-adjustable leather-rimmed steering wheel, it would be hard not to find a comfortable driving position.

Eyelines to all mirrors are good and over-shoulder blind-spots are minimal. Front and rear occupants can talk without raised voices thanks to low engine, wind and tyre noise at highway speeds.

As you’d expect, it has high build quality and a tangibly solid feel as though it was machined from a single block of steel, from the satisfying thuds of its closing doors to the absence of shudders or rattles on a variety of roads.

It also has two personalities, which can be switched in an instant. In 'Comfort' mode it will happily cruise around city and suburbs as a mild-mannered family car, fulfilling daily duties like work commutes, school drop-offs and pick-ups, supermarket shopping and the like.

However, flick the drive mode to 'Sport Plus' and you awaken, well, if not ‘the ultimate driving machine’ then something close.

Its optimised drivetrain and handling settings feel more like a sports sedan than a family car, which can turn any winding mountain road into an engaging experience.

It has impressive reserves of cornering grip and braking force, combined with sparkling engine response and fast sequential manual-shifting at your fingertips.

It feels impressively agile, with all-round response that belies its 2.0-tonne-plus kerb weight, backed by a symphony of sounds from its sublime in-line six.

This NX feels like it has lots of power in reserve when you put your foot down and never struggles going up big hills. When it’s in pure EV mode, it’s very quiet but there’s no big fanfare when this kicks over to the traditional engine. You barely notice it until you’re on the open road travelling at higher speeds, and that’s when the engine starts to sound more growly like its non-hybrid siblings.

The steering is forgiving without feeling too light and around town, the NX is nimble and sure of itself. The suspension is on the firmer side, so you’ll hear and feel the bigger bumps, but it never feels rough.

Visibility is decent with the largish windows, and the pillars that aren’t too wide from my driving position. I do like having the digital rearview mirror, though, because when you have a big car seat or tall adult in the back seat, the vision back there is hindered.

It’s pretty hard to find a modern car that’s terrible to park, especially in the mid-size SUV segment, and the NX is no different. Even in a small car space, you still have good clearance around you, which hopefully translates to less dings from neighbouring cars!

The 360-degree view camera system is top notch with its quality, and I like that the car disappears and you can see the ground underneath.

The NX comes with a maximum five-star ANCAP safety rating from testing done in 2022 and scored very highly across its individual assessment scores; 91 per cent for adult protection, 89 per cent for child protection, 83 per cent for vulnerable road user, and 92 per cent for its safety assist systems.

Eight airbags are standard which includes a front centre airbag and driver's knee airbag. 

Other safety equipment includes emergency steering assist, blind-spot monitoring, lane departure alert, lane-keeping aid, emergency lane keeping, traffic sign recognition, safe exit assist, rear cross-traffic alert, LED daytime running lights, LED cornering lights, tyre pressure monitoring, and an emergency call button.

The only safety item which can feel intrusive when driving is the adaptive cruise control as it has a feature that scans for bends in the road and will slow the car down in anticipation of them. On paper, this isn’t a bad thing but in practice, it was sporadic when it activated and sometimes slowed the car dramatically on bends you wouldn’t even call bends!

AEB with car, pedestrian, cyclist, motorcyclist, backover and intersection turning assist is standard and operates from 5.0 - 80km/h (up to 180km/h for car detection).

There are two ISOFIX child seat mounts and three top-tether anchor points in the rear row. The seat isn't wide enough to accommodate three child seats side by side, so two will fit best.

BMW covers the X5 with a five year/unlimited km warranty and offers several service plans to suit different budgets and requirements.

For example, the 'Service Inclusive Basic' package covers all scheduled services over five years/80,000km for a total of $3450, or an average of $690 per year.

The NX is offered with a five-year/unlimited-kilometre warranty, which is on par with its European rivals.

It comes with a five-year capped price servicing program, where services are competitively priced at $595 each.

Servicing intervals are reasonable at every 12 months or 15,000km, whichever occurs first.
