BMW X3 vs Lexus NX300

What's the difference?

If a BMW X3 is for you, then we have no quarrels with that. It’s a better all-round vehicle than the one it replaces and represents better value. And even though BMW mandates a hybrid driveline, there are still some significant choices within that framework.

By all means buy the M50 if you crave the rush of acceleration that almost 300kW can provide. And if efficiency is your altar of choice, then the plug-in 30e makes a lot of sense, too.

But even if you can afford either of those two more expensive variants, whatever you do, don’t dismiss the entry-level 20 model. At least drive it alongside the others and then make a decision based on all the facts, and not the assumption that entry-level equals the car you afford rather than the car you want.

It might be cheaper, but there’s absolutely no doubt that the 20 model is the one that shines and arguably makes the most of the opportunities BMW’s latest tech offers.

Sometimes less really is more.

The Lexus NX 300h F Sport is both a comfortable and luxurious family hauler that is held back by just a few things.

Of course, gripes like the underwhelming dynamics might not be an issue for all, but the less-than-stellar fuel economy (for a hybrid, at least), disappointing practicality and fiddly multimedia will affect all potential buyers.

However, this is balanced out by loads of equipment and premium appointments for a reasonable price, which should put the Lexus NX on your shopping list if you are keen for an inner-city premium SUV cruiser.

It might be badged an X3, but this is no small vehicle. In fact, it’s bigger than the original BMW X5 (which set the tone for this entire market segment) with a length of 4755mm (4667mm for the first X5) and a width of 1920mm (1872mm). That said, it’s 25mm lower than the outgoing X3 in a move to emphasise its sportiness. Shorter it may be, but it’s also 16mm wider on the front track and 45mm wider on the rear than the outgoing model.

BMWs latest styling cues also appear in the new car, including the large, split-kidney grille that, for Australian-delivered cars, is also lit around its edges. The short overhangs that characterised the original X5 (and soon characterised this whole BMW genre) remain, and the T-graphic LED tail-lights round out the stylistic touches.

The other thing we noticed (and we’ve seen it on other cars recently) is a panoramic sunroof that doesn’t actually open.

Lexus might have been known for drab and dowdy styling in the past, but the NX’s sharp aesthetic is head turning and attention grabbing in all the right ways.

Though the NX first hit Australian showrooms in 2014, after six years we reckon it wouldn’t look out of place strutting down a catwalk, and can easily hold its own in the design department against the likes of the Audi Q5, BMW X3 and Mercedes-Benz GLC.

From the front, you can’t miss the trademark Lexus spindle grille, which, with its trapezoidal shape, gives the illusion of a wider and more aggressive car.

The high-set, slender headlights also gives the NX a wide stance, while the sweeping daytime running lights and sharp bumper design give the impression that the NX is cutting through water.

In profile, the NX is characterised by a strong shoulder line, chiselled lower doors and narrow glasshouse, while the black plastic wheelarch cladding hints at its SUV status.

The black trim detailing on the tail-lights almost make it look like the NX has narrowing cartoon eyes from the rear, but the subtle diffuser and large bumper soften its look a little.

If you can’t tell, we dig the aesthetics of the NX, especially the subtle exterior features such as crystal-like front foglights and the unique side mirror design.

Step inside and those neat little design touches continue.

From the almost folded fabric-like design of the door trims to the soft-touch surfaces throughout, the NX’s cabin oozes luxury, class and quality.

The centre stack shape mirrors the front grille’s trapezoid shape, while all the buttons and switchgear have a nice heft and weight to them, and are laid out in an easy-to-use, ergonomic fashion.

Sure, look a bit closer and you might see some carryover items from lower-end Toyota models, such as the cruise control stalk but, be honest, if we didn’t point it out, would you have even noticed?

Cabin space is plentiful in the X3 with loads of room in the front, possibly thanks to the dashboard that is pulled back from you with only the twin screens and steering column offering themselves up to the driver. Even the air-vents are somewhat hidden. There’s good vision out and the seats themselves are lovely. The step into the cabin feels to be at just the right height, too; not too high, not too low.

Rear seating is good, too, although the X3 will always be better as a four seater than five thanks to the shape of the rear bench, but the glass roof opens the space up and there’s plenty of charging points and storage nooks. The sun blinds on the rear-side windows of the more expensive versions should be standard kit on every car sold in Australia.

We’ll take exception to the new gear-selector which doesn’t have a defined Park position and instead relies on applying the park-brake to engage Park. But the ambient light and contrasting cabin colours are a bit of a breath of fresh air.

There are levers in the cargo area to quickly fold the rear seats (60:40) at which point luggage space jumps from 570 litres in the mild hybrid cars to 1700 litres. The battery-pack of the 30e model means that luggage space starts at 460 litres and can be expanded to 1600 litres.

The latest version of BMW’s sometimes controversial iDrive operating system is simpler and easier to use than before and supported by a new operating system, but there’s still some familiarisation necessary. One improvement has been the addition of QuickSelect which works somewhat like the old favourites button system and gets around the need to drill into menus to access the functions you want.

A head-up display is a terrific addition, although where some displays are more tolerant of polarised sunglasses, the HUD in the BMW didn’t like mine and went dark at the most inconvenient angles.

None of the X3 variants feature a spare tyre of any sort. The 19-inch tyres on the base grade are run-flats, while everything else gets a repair kit for roadside emergencies.

If you want to tow, the good news is that all X3 variants can do so. But you will need to purchase the $2200 towing package which enables the X3 to haul a trailer weighing up to 2000kg with a maximum tow-ball down-weight of 200kg.

Measuring 4660mm long, 1870mm wide, 1645mm tall and with a 2600mm wheelbase, the NX puts it foot firmly into the mid-size SUV class.

Front occupants can easily get comfortable thanks to seats with a wide breadth of adjustment, while drivers also get a telescoping steering wheel that automatically raises when the car is turned off for easier ingress/egress.

Generous door bins up front will swallow large water bottles and any other paraphernalia, while two deep cupholders are found between the driver and front passengers.

If you want to tuck any items out of sight though, the glovebox and centre console bin will do the job, but there is also a hidden compartment where the driver’s touchpad palm rest.

Lift up the flap and your precious valuables can be hidden away, but look underneath the flap and it doubles as a handheld mirror to check you don’t have any food in your teeth before a date.

The outer two second-row seats offer ample room for six-foot-tall passengers, and – even with the front seats in our preferred position – there is plenty of legroom in the back.

Like most vehicles, the middle seat is a bit compromised, but in the NX it feels especially narrow and uncomfortable.

This isn’t helped by the middle seat’s seat belt, which comes down from the roof and intrudes well into the backrest of the neighbouring seat when not in use.

It makes loading the NX full of passengers tricky as there is a bit of shuffling around to get all the belts in place and passengers comfortable.

Our advice? Use the NX as a four-seater and just fold down the centre armrest, which also exposes two cupholders, for extra comfort.

Other rear seat amenities include air vents and storage pockets in the doors, the latter of which will accommodate water bottles or small items.

Open the boot and the NX will swallow 475 litres of volume, which can expand to 1520L with the rear seats folded down.

Boot space is down on its rivals, with all of the German models offering at least 550L of volume.

In real-world terms, this means the NX’s boot won’t close with a large- and medium-sized suitcase sat side-by-side, but has no problem with smaller cases.

Boot space might be lacking in the NX, but the hybrid system’s batteries have to go somewhere, and at least Lexus offers up two big bag books and tie-down points.

The Lexus NX mid-size SUV range kicks off at $55,700 before on-road costs for the base 300 Luxury 2WD, but our NX 300h F Sport AWD test car carries a $68,700 pricetag.

Of course, the price goes up due to the petrol-electric hybrid engine (more on that below), all-wheel-drive set-up and sporty appointments of the F Sport grade, but the list of standard equipment is sizeable.

From the factory, our test car is fitted with privacy glass, roof rails, auto-dipping and heated side mirrors, 4.2-inch driver display, keyless entry and push-button start, dual-zone climate control, wireless phone charger and powered tailgate as standard.

F Sport grades also score unique 18-inch wheels, a lowered ride-height and sports bodykit, as well as a bespoke leather shift knob, steering wheel with paddle shifters, seats, and interior trim.

Speaking of seats, the front pair are heated and cooled, and also feature electronic adjustment with memory function.

Handling multimedia duties is a 10.3-inch widescreen that outputs to 10 speakers dotted around the cabin., Digital radio, satellite navigation, Bluetooth connectivity, Apple CarPlay/Android Auto support and a DVD player can be found within the multimedia system, which is controlled by a central touchpad or via voice commands.

The only option ticked on our car is the Titanium premium paint. The only standard colour for the NX 300h F Sport is Onyx (black), with all other colour options incurring a $1500 penalty.

Of note, Lexus keeps the sunroof and colour head-up display on the options list.

While the 300h F Sport might be close to the top-end of the NX hierarchy (only cheaper than the Sports Luxury trims), its $68,700 asking price is comparable to base grades of key German rivals, such as the Mercedes-Benz GLC ($67,400) and BMW X3 ($68,900) that are rear-driven and offer less equipment.

Hybrid tech across the board is the key phrase here, with the base-model 20 xDrive fitted with a mild hybrid electric motor and battery pack that works in conjunction with the 2.0-litre, turbocharged petrol four-cylinder engine. Power is 140kW and torque 310Nm. Like most mild hybrids, the electric motor offers power regeneration during braking, a mellow (by EV standards) kick in the pants during take-off and acceleration and also acts as the car’s starter motor.

The performance flagship, the M50 xDrive taps into the same technical philosophy with a mild hybrid augmenting the turbocharged six-cylinder inline petrol engine. In this case, however, peak power is a hefty 293kW and torque maxes out at 580Nm.

The most technically adventurous X3 is the 30e xDrive which uses plug-in hybrid tech to offer a claimed 91km of electric driving, about twice that offered by the original X3 PHEV it replaces. When the same 2.0-litre four-cylinder petrol as fitted to the 20 xDrive, and the electric motor are humming along together, there’s 220kW of power and 450Nm for the taking. The PHEV X3 can run in purely electric mode at up to a claimed 140km/h.

All variants use BMW’s familiar eight-speed automatic transmission and in each case, drive is sent to all four wheels on a permanent basis. Interestingly, the 30e and M50 versions package their electric motor as part of the engine-transmission combination. The 20, meanwhile, places its electric motor externally, as part of the drive-belt rotating assembly.

The M50 model has an M button that unleashes the full performance with one touch, and features an electronically locking rear differential in the interests of high-speed turn-in.

Adaptive suspension that varies the degree of damping is also part of the package on each X3 variant.

Propelling the Lexus NX 300h F Sport is a petrol-electric mild-hybrid powertrain, combining a 114kW/210Nm 2.5-litre naturally aspirated four-cylinder petrol engine with two electric motors – 105kW/270Nm unit for the front axle and a 50kW/139Nm unit for the rear wheels.

The total system output is measured at 147kW, which is sent to all four wheels in our test var via a continuously variable automatic transmission (CVT).

The zero-to-100km/h acceleration takes 9.2 seconds thanks to a fairly hefty 1895kg kerb weight.

As you might expect, the PHEV 30e model is the efficiency superstar of the X3 line-up with an official combined test figure of just 1.6 litres per 100km and 38 grams of CO2 per kilometre. The four-cylinder 20 xDrive is not bad for its size at 7.5L/100km (and 171g), yet the bruising six-cylinder M50 version with all that performance is not too far behind with an official figure of 8.2L/100km (187g).

The 30e PHEV features a selectable battery-saving mode as well as the option of forcing EV-only running. It features a 19.7kWh battery and BMW claims it can charge using a three-phase, 11kW socket from empty to full in two hours, 15 minutes. It does not make use of fast-chargers.

Exactly how far you’ll travel in the PHEV model will depend hugely on how and where you drive. On long, open road journeys, fuel consumption won’t be much different to the others, but with just a 50-litre fuel tank, it’s range won’t be stellar. But in urban running where the batteries are being recharged for free as you brake, the difference will be significant. Meanwhile, with a 65-litre fuel tank in the mild hybrid grades, the theoretical range (based on the official fuel number) is 865km and 765km for the 20 and M50 respectively.

While BMW recommends premium fuel for maximum efficiency, it also says that each X3 variant will not be harmed by the use of standard ULP if that’s all you can get hold of.

Official fuel consumption figures for the Lexus NX 300h is 5.7/ litres per 100km, though we managed a 7.6L/100km figure in our week with the car.

Our driving consisted exclusively of inner-city driving for groceries and just two trips down the freeway upon collecting and returning the car due to Melbourne’s lockdown rules.

Big heavy SUVS like this one haven’t always been too dainty on their feet. The extra bulk and height mean suspension has to be firmer, the big wheels and subsequent loss of tyre sidewall depth plays against ride quality and before you know it, the compromises have piled up and the driving experience has gone to hell.

This time, however, BMW’s claim that the X3 was designed from the start as an SUV and not converted from a sedan platform seems to hold water. There’s an overall greater sense of cohesion in the way the car steers and flows through corners and faster bends. The steering feel and feedback are a big part of that, too, and the whole seems at least as great as its parts.

The M50 is, predictably, a rocket with loads of accessible acceleration and a great noise while you’re enjoying it. That said, the 21-inch wheels and tyres don’t do anything for ride quality, but it remains an entertaining performance car in a familiar, ICE kind of way.

The plug-in is also perky with its 220kW on tap, but it’s less old-school and more techy. And while you can’t pick the point at which ICE hands over to electric and vice-versa, sensitive drivers will absolutely know that there’s a big dollop of electrical assistance when your right foot starts asking the tough questions. It definitely feels more overtly hybrid, though that shouldn’t be any kind of surprise, purely because that’s precisely the case.

Which brings us to the 20 entry-level grade. And while it’s going to be a controversial statement, this emerges as the most cohesive, rounded variant of the new X3. There’s something in the way the fizzy, bubbly (but very smooth) 2.0-litre four-cylinder provides more than enough urge, but never threatens to dominate the dynamics.

With less weight over the front wheels than the M50, and less weight overall than the PHEV, the 20 corners flatter, steers more intuitively and is simply more fun more of the time. Even on the optional 20-inch tyres, it rides better than the others, too, and might even be better again with the standard 19s other than the fact that those are run flats and we didn’t get try them.

Though the Lexus NX might look sporty and dynamic from the outside, don’t be mistaken into thinking Lexus’ mid-size SUV is anything other than a comfy cruiser.

Steering remains light and lifeless in its default ‘Nomal’ drive mode, but even in ‘Sport S’ and ‘Sport S+’, weighting feels artificial and numb.

What this means is that the NX 300h F Sport is a joy to manoeuvre around town at low speeds, but is found lacking when the speedo climbs and the roads get a bit twisty.

Likewise, a stab of the throttle is met with a spike in revs and engine noise as the powertrain switches from its electric motor to internal combustion engine, but the expected thrust-burst never comes.

CVTs are generally tuned for better fuel economy, not a sporting drive, so it makes sense that the NX is a little more hesitant and lethargic to get up to speed, but the transmission does suffer from that ‘elastic’ feel where it can be slow to ‘shift up’ if it thinks you are wanting a sporty drive.

However, these shortcomings are especially evident when stacking it up next to the new Toyota RAV4 hybrid.

The NX is underpinned by Toyota’s MC platform, shared with the old RAV4, whereas the fifth-generation mid-size SUV that launched in 2019 is updated with a TNGA platform.

Much of our aforementioned criticisms in driving dynamics and snoozy drivetrain are fixed, or at least alleviated, in the latest Toyota RAV4, so here’s hoping the next-gen NX rumoured to break cover soon will be a welcomed step forward.

And while the current Lexus NX is certainly not the last world in SUV driving dynamics, it’s not trying to be.

As a daily runabout for the family, the NX is comfortable and predictable – just what some families might be after.

The suspension does a great job at soaking up road imperfections and little bumps you might find on your journey, helped by the comfy seats and great interior sound insulation.

What is noticeable though, is overcoming large bumps or any change in elevation at speed, where the NX 300h’s hefty weight means it takes just a touch longer to get settled again.

The cabin also feels a bit fussy from the driver’s seat, with the multimedia especially being fiddly and hard to navigate when on the move.

We reckon a rotary controller like those found on a BMW, or even better multimedia software as seen with a Benz, could go a long way in fixing Lexus’ multimedia woes.

Having said that, the system is compatible with Android Auto, and is laid out well on the widescreen, so you could easily forgo the annoying touchpad and janky software for a better experience.

All Lexus NX grades carry a maximum five-star ANCAP safety rating, applicable to all variants of introduced from October 2017 onwards.

As the NX was tested on ANCAP’s old standards, it scored 35.39 out of a possible 37, dropping only 1.61 points in the frontal offset test for ‘acceptable’ protection of the driver’s chest and feet, and passenger’s lower legs.

Like all NX models sold in Australia, our car came with the brand’s Safety System+ suite, which includes autonomous emergency braking with pedestrian detection, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control and lane departure warning.

Other safety tech in our F-Sport grade includes hill-start assist, automatic headlights and adaptive highbeams, while eight airbags, seatbelt pretensioners and a tyre pressure warning system are found throughout the local NX line-up.

BMW’s warranty on the X3 is the company’s usual five-year/unlimited kilometre deal. But in this case, there’s also a six-year/100,000km warranty on the high-voltage battery.

Also typical for BMW is the service interval which is not a set time or distance and instead is determined by how the car has been used. It’s called condition-based servicing and it’s nothing new at BMW.

There’s also capped-price servicing available. For the X3, the five-year/80,000km service package is $2475.

Like all new Lexus vehicles, the NX 300h F Sport comes with a four-year/100,000km warranty, along with roadside assist over the same period. A six-year anti-corrosion is also part of the aftersales assurance package.

Scheduled service intervals are every 12 months/15,000km, whichever comes first.

The first three years/45,000km of scheduled servicing is capped at $495 for each annual service, which falls under the brand’s Encore service that also entails pickup and delivery of the NX, loan car, and wash and vacuum.

Lexus ownership also means owners will be access to exclusive events, dinners and drive days, as well as promotions from partner hotels.

Although servicing costs are relatively cheap for the first three years, Lexus’ four-year/100,000km lags behind luxury brand leaders Mercedes-Benz and Genesis, who both offer five-years/unlimited kilometre assurances.
