Lexus NX450H+ vs Smart 1

What's the difference?

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.

It’s easy to get lost in marketing hype, but — based on first impressions — the Smart #1 does what it says on the tin. This is a Chinese-built SUV that feels more premium than most, and one which is priced to tempt you from one of the German big three. The warranty isn’t good enough, though, and the multimedia screen can be infuriating, but it drives very nicely, especially on suburban roads.

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

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.

There is an impossibility pretty model in Smart’s new line-up, but the #1 ain’t it. While the #3 — which has also just launched — is a sleek-looking, coupe-style SUV, the #1 is a top-heavy small SUV that doesn’t shine from every angle.

Front-on, or from a front three-quarter angle, the #1 definitely works, with the brand setting out to remove unnecessary fussiness from the design, leaving smooth and rounded bodywork in its place.

There are no body creases or weird angles here, instead it’s a smooth, fluid-like design that flows from the front LED lights bar to the smooth shoulder lines to the matching light treatment at the rear. 

But it’s at the rear where, for mine, the design begins to fall over. From that angle, the #1 looks skinny and top-heavy, especially when wearing the red hat of the Brabus model.

Still, eye of the beholder and all that.

Inside, though, the #1 kicks all sorts of goals, presenting as a properly premium-feeling EV space that’s swimming with technology and lovely cabin materials.

I particularly love the letterbox-style screen that replaces the traditional dashboard. It’s not distracting or overbearing like some twin-screen set-ups, but clearly shows you the key driving stuff you need when you’re on the road.

Side note, though, the massive central screen is super clear and lightning fast, but as usual you need to spend some (a lot) of time with it to figure out where all the functions are hiding, with most of the car’s key controls hidden within its labyrinth.

And side note two, the background graphics look like they were designed by a cordial-addled child, it is busy, cartoonish and out of keeping with the calm, grown-up nature of the #1’s cabin.

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.

The Smart #1 measures just under 4.3m long, just over 1.8m in width and around 1.6m in height, and it rides on a 2.75m wheelbase. And the perk of the Smart’s EV powertrain, the brand says, is Mercedes-Benz E-Class levels of space in the back seat, despite the #1’s diminutive footprint.

It’s a big claim, and while I didn’t break out the tape measure I can say the backseat feels plenty generous, and because the rear pew slides forwards or backwards by 15cm, you can choose whether you want more legroom or more luggage space.

Speaking of which, pop the auto-opening boot (by hitting the ‘a’ in the ‘Smart’ lettering, which I couldn’t figure out without help) and you’ll find 323 litres of space with the back seat as far back as it goes, growing to 411 litres with it pushed all the way forward. There’s also a 15-litre frunk.

Smart says the #1 weighs 1800kg, adding it will tow 1600kg — but I’m sure you can imagine the impact a heavy load will have on your driving range.

The #1 is available in three trim levels — the Pro+, Premium and Brabus — and pricing (before on-road costs) climbs from $54,900 to $58,900 and $67,900. 

Brabus, by the way, was a lesser-known Mercedes-Benz tuning arm, a little like AMG, which should give you some idea of what to expect from the performance-badged models.

Anyway, that pricing is good enough to undercut key rivals, including the Volvo EX30 (from $59,990) and BMW iX1 ($78,900), and it’s drastically less than Mercedes-Benz's EQA 250 ($84,900), all before on-road costs.

Also firmly in the Smart’s favour is that there isn’t a cheap-feeling model among them, with even the Pro+ feeling properly well-equipped and premium.

Entry-level cars score 19-inch alloys, a panoramic roof, LED lighting, a powered tailgate and a 12.8-inch central screen with wireless Apple CarPlay and Android Auto, and a 9.2-inch digital dashboard. There’s wireless device charging and a decent stereo, too.

The Premium then adds matrix LED headlights, leather trim, a huge head-up display and a better Beats stereo, while the Brabus scores a unique interior and exterior treatment, better suspension and a launch control function.

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.

There are two drivetrains on offer here - one shared across the Pro+ and Premium, and another delivering the prodigious power of the #1 Brabus.

The first shared option is a single rear motor that delivers 200kW and 343Nm, which is enough to knock off the sprint to 100km/h in 6.7 seconds. Top speed for all models is listed as 180km/h.

The Brabus, though, adds a motor at the front axle, giving it AWD, which ups the outputs to a punchy 315kW and 543Nm, dropping the sprint to 100km/h to a very fast-feeling 3.9 seconds.

It’s a single-speed EV transmission in each, which means smooth, constant power delivery with no traditional ‘steps’, and all get 'Eco', 'Normal' and 'Sport' drive modes, though the only thing they impact is the accelerator response.

You can add weight to the steering, but that’s a separate item accessed elsewhere in the screen’s sub-menus.

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.

All Smart #1 models share the same 66kWh battery, but how far you can travel between charges comes down to the trim you choose, with the WLTP driving range either 400km, 420km or 440km. The Brabus, of course, covers the least ground between charges, owing to its dual-motor set-up and amped up power outputs. 

When it comes time to plug in, all models are equipped with 150kW DC fast-charging capability, and when plugged into said charger, you can expect to go from zero to 80 per cent charged in less than 30 minutes. 

There’s also 22kW AC charging on board in the Premium and Brabus models, which means you can use three-phase power, but plugged into a regular 7.4kWh home wallbox should see you go from zero to 80 per cent charged in 7.5 hours, which means overnight charging should work a treat.

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 #1 and its sister car, the #3, might share powertrains and batteries, but they are designed to drive very differently. The #3 is the sporty one (always code for a firmer ride), while the #1 is supposed to be softer, more comfortable and more city-friendly.

That’s the theory, at least. In practice, I have no idea. My time behind the wheel of the #1 was limited to its most fire-breathing model — the Brabus, which also scores its own suspension components — and soft is not a word that comes to mind once you’re strapped in behind its bright red seatbelt.

It begins with those bonkers power outputs, 315kW and 543Nm, which deliver genuine push-you-back-in-your-seat acceleration every time you stand on the go pedal.

Better still (well, I think so, at least), is that activating its sportiest 'Brabus' mode also unlocks a deep Abarth-style burbling soundtrack that rises and falls with your inputs.

But like most performance EVs, you can also dial the drive experience right back. In its softer drive modes the #1 Brabus feels calm and comfortable and not overly reactive, which makes sense, given the only thing the Brabus mode changes is accelerator sensitivity.

The result, though, is a car that you can tootle around in silently when you want to but hides a nuclear weapon under your right foot when you want to unleash that part of its personality. 

Downsides? It’s got plenty of point-and-shoot power, but in the few corners we managed to find in it, it didn’t quite live up to the all-out-performance badge. There’s a bit too much movement in the body — a symptom of its near-2.0-tonne weight — and it doesn’t feel entirely engaging.

A couple of important caveats, though. We didn’t get long behind the wheel of the #1, and the dull-as-dishwater prescribed drive program revealed little about its true performance potential. So, we’ll have to wait until the model is properly through the CarsGuide garage to give you a deeper dive on this one.

Full credit to Smart on this one, because the #1 comes with a pretty stacked active (crash avoidance) safety tech list, and though our test drive was far from exhaustive, only the speed limit warning (which you can switch off) felt overly intrusive, with the rest just sort of humming away in the background.

The full package includes things like adaptive cruise control, lane keeping assist, traffic-sign recognition and the aforementioned speed limit warning. There’s also AEB, along with seven airbags, all of which has earned the #1 a five-star Euro NCAP safety rating.

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.

Warranty is a definite soft spot, with LSH Auto offering five years or 150,000km, whichever comes first. For reference, other Chinese newcomers include Chery (seven years) BYD (six years) and GWM (seven years), while MG has just shifted to a 10-year warranty.

Still, service intervals are 12 months/20,000km, and you should be able to take your Smart to any LSH Auto Mercedes dealership (in Melbourne, Brisbane and Sydney) or either of the Smart dealerships in Sydney or Brisbane.

Service cost for the first four years averages $611 per workshop visit for the Pro+ and Premium (worth noting the fourth service is a big one) and $780 for the Brabus. Not particularly small numbers.
