Lexus NX300H vs Mercedes-Benz E220

What's the difference?

The all-new NX is a massive step forward over its popular predecessor.

In every way, it is an improvement, with better refinement, comfort, performance, efficiency, safety and choice.

Indeed, look out, Audi, BMW, Mercedes and Volvo: the NX has finally come of age. If we were in the market for a luxury medium-sized SUV, we'd definitely have the Lexus on our shortlist, especially the incredibly efficient hybrids.

Europe, you've been warned.

Given Mercedes-Benz's rich heritage with station wagons, it is a bit of a shame Australia’s preference for SUVs has reduced the line-up to just one variant this time around.

I'm glad they've picked the All-Terrain to fly the flag though, and Merc wagon loyalists should appreciate the extra versatility of its dirt road ability - if they're not mourning the loss of the extra two seats in the rear. Like the rest of the current E-Class range, the E 220 d All-Terrain is an excellent product overall.

UX, NX, RX, LX, RZ... Lexus' nonsensical naming strategy can be quite flummoxing.

Just remember that the NX sits above the smaller UX but below the larger RX in the brand's burgeoning SUV stable. It's also closely related to the wildly-popular Toyota RAV4 – though you'd never know by looking at them side-by-side.

At first it may look much like the old model, but the new NX has switched to the latest RAV4's advanced Toyota New Global Architecture, known as GA-K in Lexus' lexicon.

Basically, it allows for a vehicle that's between 20 and 30 mm larger than before, to help improve overall proportions. And with this considerably bigger canvas to work on, it also means that Lexus's stylists have had more freedom to evolve the brand's design language. Albeit at a glacial pace from an exterior point of view.

Starting from the front, the controversial 'spindle' grille has been toned down a bit and the headlights have a neat Lexus 'lightning rod' tick motif, while – looking at the side profile – a startlingly cab-backward shape gives it a surprisingly sleek silhouette.

The extra length and stretched wheelbase let the design to breathe more than before, bringing with it a more graceful and elegant aesthetic.

Finally – and this is a brand first – the new NX's rather nondescript rear has 'LEXUS' spelled out in letters, with no sign of the company logo.

The All-Terrain styling pack is comprised of tough-looking front and rear bumpers, with unpainted plastic side skirts and wheelarch flares on all corners. This will all be welcomed by anyone who travels regularly on dirt roads, but the All-Terrain bits will also provide a handy disguise from urban parking scrapes.

The double-blade grille, wheels and roof rails are also bespoke to the All-Terrain, and the net result is a distinct personality that should satisfy the majority of previous E-Class Estate buyers previously opting for the AMG styling pack.

Interior trim is based on the regular E-Class Avantgarde package, but with specific rubber studded pedals and All-Terrain branded floor mats to align with the exterior treatment.

In the default suspension setting, the All-Terrain sits 29mm higher than a regular E-Class. Taller tyres make up 14mm of this, while the remaining 15mm is thanks to an elevated 'Air Body Control' air suspension. A further 20mm of lift is available with the All-Terrain drive mode selected, but only at speeds up to 35km/h.
 
The All-Terrain’s 20-inch alloys are a staggered fitment with 245/40 tyres up front and 275/35 at the rear, while taller-sidewalled 245/45R19 at each corner are a no-cost option, and essential if you wish to use snow chains.

Like the Estate available internationally, the All-Terrain rides on the same 2939mm wheelbase as the E-Class sedan but gains an extra 24mm in rear overhang to measure 4947mm overall.

The wagon body, extra kit and all-wheel drivetrain also add an extra 240kg to the kerb weight over the E 220 d sedan, with the All-Terrain tipping the scales at 1920kg.

For the really big design step-change, you'll need to step inside...

Hallelujah! Lexus has finally forsaken its weird, futuristic dash design elements for a simpler and far-more intuitive look that finally banishes unnecessary complication while still appearing progressive.

Somehow, there are now 33 fewer switches than before, aided by permanent virtual short-cut buttons on both of the touchscreens on offer.

Lexus has clearly been listening!

So, now, what we have here is an attractive, functional and superbly built interior (save for a couple of very-atypical Lexus rattles in these early production cars we drove), boasting quality materials that rate highly on all the important sensory metrics: lush to the touch, easy on the eyes and lovely to breathe in... and breathe out again!

Other plus points include a gorgeous steering wheel, attractive instrument dials, endless storage and climate control that's so effective it pretty much creates a microclimate within your personal space.

Brilliant seats, with ample adjustability, provide comfort and support even after hours ensconced within them, while the driving position is enhanced by thoughtful placement of most major controls - including the natty little gear lever and big old paddle shifters.

It's also worth pointing out a couple of surprise-and-delight features – starting with the 'e-latch' electric door handles, with sensors that delay opening if there are cyclists or pedestrians on approach to prevent striking them, as well as a manual override should the battery go flat.

There's more, like the wireless phone charger tray that also slides to reveal a hidden cubby area; centre-console lid that opens sideways FROM BOTH DIRECTIONS – what sort of sorcery is this?? – and optional digital rear-view mirror that works like X-ray vision in seeing through obstructions... handy for when back-seat passengers' beehives block the back view out.

However, after lavishing such intricate attention to detail, why does the instrument cluster's digital trip computer use the same cheap style and font as found in a lowly Yaris? It takes you completely out of the Lexus state-of-mind.

And, like me, you might lose your mind with the infuriatingly fiddly capacitive touch controls on models with the HUD. While it does provide a broad range of functionality that's displayed on the windscreen view, it's difficult to modulate accurately, and doesn't operate intuitively. Remnants of the fiddly old touchpad from the previous NX. Why can't Lexus just abandon such needless complexity? After a while I worked it out – but it's deeply distracting to use.

Oh well. At least the rear seat area is an improvement over the old NX, with more space, comfort and convenience features. Entry/egress is easy, with wide apertures that ought to make fitting in child seats less of a chore than before.

Most adults should find sufficient leg, knee, shoulder and head room back there, though a trio of adults might result in a very tight fit.

Rear facing air vents (with climate control functionality on higher grades), 12V power outlets, twin USB ports and a wide centre armrest with cupholders are included.

Further back, there's a handy (though not class-leading) 520 litres of luggage space regardless of powertrain, expanding to 1411L when the rear backrests are folded. Access is easy thanks to the wide door and flat floor, where a bit of extra storage and even space for the cargo blind are provided. Thanks, Lexus.

Note, though, that runflat tyres take the place of any spare wheel – a bummer if you're out on deserted country road late at night with no help in sight.

Aside from the All-Terrain’s rugged looks, the greatest departure from E-Class Estate tradition is the omission of the third row of seats, which makes this one a strict five-seater.

One could argue that the Estate’s traditional rearward-facing third row is a bit old school next to the forward-facing setup used by seven-seat SUVs like the GLS, but it's a shame given the third row is still available in other markets.

The All-Terrain does offer a vast cargo area however, with an extra 130 litres (VDA) over the sedan with the seats up to total 670 litres (VDA). Seats down, this extends to 1820 litres (VDA), but it’s worth noting that both wagon figures are marginally smaller than the previous Estate’s 695/1950 measurements.

Facilitating full use of this space is the classic Merc Estate retractable cargo net, and a 670kg payload promises good scope for loading beyond a full passenger count. The air suspension will also automatically maintain a level ride height regardless of load.

As with all current E-Classes, there are bottle holders in each door plus two cupholders front and back and ISOFIX child seat mounts in the outward rear positions.

As per the non-AMG Mercedes passenger car norm, run flat tyres take the place of a spare tyre, but a space saver can be optioned to sit above the boot floor.

The All-Terrain theme follows the same path taken by key rivals Audi and Volvo with the A6 Allroad ($112,855) and V90 Cross Country ($99,900), which leaves BMW’s upcoming 5 Series Touring as the sole option in this segment not to adopt the semi-SUV look.

The $109,900 Mercedes is priced right between the Audi and Volvo, but note that the Audi brings a more powerful V6 to justify its slight premium.

The All-Terrain is available with a V6 internationally, but the 220 d four-cylinder diesel was selected for Australia as it's the closest match for the E 250 d that proved the most popular variant last time around.

Compared with a similarly specified E 220 d sedan (which kicks off at $92,900), Mercedes reckons they're about the same on price, but the All-Terrain throws in the wagon body and all-wheel drive pretty much for free. The All-Terrain also offers a significant value improvement over the previous E 250 d Estate which bowed out at $107,900.

Key inclusions for the All-Terrain over the already opulent E-Class are genuine leather trim, proximity unlocking, widescreen dash instrument that spans two thirds of the cabin, LED 'Multibeam' headlights, underbody protection and 20-inch twinned five-spoke alloys.

Here is where the NX shines, with clear options that provide very obvious benefits according to wants, needs and budgets. And there are even fundamental differences compared to the RAV4 powertrain, further justifying that premium 'L' badge experience.

Let's divide these into petrol and petrol-electric hybrid models, with petrols first.

The NX 250 is powered by a 2487cc 2.5-litre naturally aspirated direct-injection twin-cam four-cylinder engine, producing a healthy 152kW of power at a heady 6600rpm, and 243Nm of torque from 4000rpm to 5000rpm.

Drive is sent to the front wheels only, via an eight-speed torque-converter automatic. Tipping the scales at 1705kg, it's the lightest NX on offer, and thus delivers 89.1kW per tonne.

The NX 350 turbo version, meanwhile, uses a somewhat different four-cylinder engine as well as a variation of the eight-speed auto. A 2393cc 2.4-litre turbo unit, it pumps out 205kW at 6000rpm and 430Nm from a low 1700-3600rpm. It's also AWD only, which adds kilos. That said, coming in at 1860kg, its power-to-weight ratio is a stirring 110.2kW/tonne.

Moving to the series/parallel hybrids, both the expected-bestselling NX 350h and the intriguing new NX 450h+ PHEV are based on that 2487cc 2.5-litre four-cylinder atmo unit, tuned this time to offer 140kW and 136kW (at 6000rpm) and 239Nm/227Nm (from 4300-4500rpm and 3200-3700rpm) in the NX 350h and NX 450h+ respectively.

The NX 350h uses either a single synchronous permanent magnet 134kW/270Nm electric motor in the front-drive version, or two electric motors (adding a 40kW/121Nm generator on the rear, double wishbone axle) to create the AWD alternative. Their combined total power rating is 179kW. The NX 450h+ ups that to 227kW.

None are light, however. While the NX 350h 2WD weighs a reasonable 1810kg, the twin-motor AWD system bumps that up to 1870kg, while the NX 450h+ is a portly 2050kg. Result? The power-to-weight ratio for all three are 98.9kW/tonne, 95.7kW/tonne and 110.7kW/tonne – almost identical to that of the NX 350 turbo.

The hybrids' gearbox in question is an 'e-CVT' electronic continuously variable transmission, working with a lithium-ion high-voltage battery, while the NX 450h+'s EV drive's battery is an 18.1kWh unit.

So, no prizes for guessing which one is the most frugal...

The All-Terrain’s excellent 2.0-litre turbo-diesel engine and nine-speed torque converter auto are carried across from the E 220 d sedan, which produces a decent 143kW/400Nm. Max torque is available from 1600-2800rpm.

The All-Terrain is the only Australian E-Class to pair this engine with the '4Matic' all-wheel drivetrain though, which uses a slightly rear-biased (45/55) torque split in this application.

All NXs require 95 RON premium unleaded petrol, and are emissions rated at Euro6b.

Not surprisingly, on the official combined run, thirstiest of the lot is the NX 350 turbo at 8.1L/100km (for a carbon dioxide emissions rating of 185 grams per kilometre), followed by the NX 250 at 6.9L/100km (158g/km).

The NX 350h cut that down to 5.0L/100km (113g/km for the FWD and 114g/km for AWD), while the NX 450h+, naturally, is the most economical by far, slashing that down to just 1.3L/100km, or 29g/km.

While we can't tell you what the NX 450h+ managed on test, the others didn't quite match their official numbers. Over several hundred kilometres, the NX 350 ranged from 9.3-11.3L/100km, the NX 250 7.5-9.3L/100km and the NX 350h from 5.7-6.8L/100km.

Note that the NX 450h+'s 18.1kW battery can only be charged using an AC outlet, meaning it'll need about 2.5hr to get the job done. Its EV-only range is about 70km on the WLTP score, or 87km using the less-realistic NEDC method.

At 55 litres, the fuel tank will allow the following combined average range between refills: 679km (NX 350 turbo), 797km (NX 250), 1100km (NX 350h) and a barely believable 4231km (NX 450h+, naturally).

The All-Terrain’s extra 240kg and no doubt less slippery body add 1.6L/100km to the E 220 d sedan official combined fuel consumption figure, but the wagon’s 5.7L/100km claim is still very impressive for a taller body nudging two tonnes. 

At this rate, the E-Class All-Terrain has a theoretical range of 1157km from its 66-litre fuel tank.

The previous NX looked better than it drove.

Based on the previous-gen RAV4, it failed to rise above such humble underpinnings, despite all the extra design, comfort and equipment features Lexus created to help it do just that.

Sure, there were some very appealing things going on, including attractive styling, an intriguing interior, sumptuous seats and lots of kit to play with, but the Toyota's noisy, fidgety and tiring DNA soon became apparent, especially compared to rival luxury midsizers. And some of the dashboard multimedia controls were just down-right madness.

Building on the latest RAV4's set of modern, competent components, however, has fundamentally changed the NX.

For starters, it's much quieter inside. Whether at idle, travelling at speed, or traversing some pretty rough patches of road, the NX at last rides like something you'd expect a Lexus should. And given how noisy and droney most of its European rivals also are on Aussie bitumen, it gives the Japanese contender a handy head-start.

The same applies to how enveloping the soft yet supportive seats are, how settled the suspension feels and how calm the experience is. No previous Lexus SUV has seemed so... refined. Even the really big, expensive ones.

From the driver's point of view, the steering is beautifully balanced, for precise yet reassuring control at speed. This varies according to which grade you're driving, but as a whole, while not sporty like a BMW's nor as fluid as, say, a Mazda CX-5's helm, the Lexus walks that line between easy and involving quite well.

Ditto the handling and roadholding. The lightest of the bunch – the petrol-powered NX 250 and NX 350 turbo – feel ripe and ready for a hustle along a curvy ribbon of road, coming across as taut enough for tight turns yet supple enough to soak up the many bumps and thumps thrown up at them.

Switching to the NX 350h hybrid, there's a greater sense of mass, whether driving the front-drive 2WD or even heavier AWD version. As such, it's still quite dynamic, but not as athletic as the petrol-only models.

In terms of performance, there are no duds – and that's no surprise, as the previous NX's powertrains were pretty sound as well.

Though simply a front-drive version of the RAV4 Edge's 2.5-litre unit, the NX 250 seems more muted than the Toyota's application, and yet is willing to rev hard to hit the power band necessary for it to feel alive. At higher speeds, sometimes the raspy engine can sound a tad noisy when extended, but it's never harsh or rough.

Moving on to the NX 350h, it feels like, well, a heavier and quieter RAV4, not unexpectedly. Silent at take-off speeds, the engine chimes in fairly unobtrusively, providing plenty of oomph along the way, while the CVT seamlessly slices through each (artificial) ratios. After the petrol versions, the steering does seem a little more remote, and you can feel the extra heft through turns, but – again – the basics underneath seem right.

Accelerating hard on the open road does reveal that typical Toyota hybrid engine roar and CVT flair, but only when the throttle is prodded hard. Driven normally, the NX 350h is as smooth, swift and sweet as you'd expect. And definitely in keeping with brand performance expectations.

Finally, there's the NX 450h+ F Sport. At over two tonnes, Toyota and Lexus' plug-in hybrid debutante is not a flyweight by any means, yet having all that extra low-down mass does result in a slightly different driving experience.

Take acceleration: having access to 227kW of power and torque together at very low revs equals lots of thrust right from the get-go. And while it's not sports-SUV rapid, there's certainly enough punch to justify the F Sport badge. Similarly, the low centre of gravity that the 18.1kWh battery pack provides seems to promote hunkered-down road-holding attitude through tight turns, with minimal body roll.

Regardless of which NX you're looking at, quibbles are few. Occasional road and tyre roar are still a little evident over some surfaces; the adaptive cruise control and lane-keep technologies could benefit from some local fine-tuning so they behave a little more nuanced in Australian conditions (and that applies to most luxury SUVs nowadays); and the optional head-up display's capacitive controls located on the steering wheel spokes are distracting, difficult to modulate and needlessly complicated. They're so annoying we'd even untick the Sport Luxury option box to avoid it.

If we had to choose a favourite among the new NXs, it would probably be the NX 350h F Sport, since its adaptive sports chassis provides the best compromise between agility and suppleness; the NX 350 turbo is probably the most fun to drive hard and fast, while the base NX 250 is thoroughly competent and sufficiently luxurious to scare most rivals.

Could this really be a medium-sized Lexus SUV we're talking about?

We're not saying that the latest NX is perfect, but it now provides a very compelling argument not to buy European.

Climbing aboard the All-Terrain, there’s a sense you're seated higher than its 29mm static ride height lift suggests. It's probably mostly psychological, and borne from the All-Terrain styling treatment, but something SUV fans will probably appreciate.

Otherwise it's mainly W213-generation E-Class from the driver's seat, which is a very good thing.

However, the extra 240kg of Estate body and All-Terrain spec over a regular E 220 d sedan is just enough to put a dent in the 2.0-litre diesel's performance. Mercedes claims an 8.0sec 0-100km/h figure, which is still more than enough to keep up with traffic, but just not as spritely as the sedan’s 7.3sec figure.

The combination of airbag suspension and the All-Terrain’s slightly taller tyre sidewalls help the wagon ride commendably well. There's no disguising the large-diameter 20-inch wheels over sharp potholes, but the experience is generally even better than we recall from any other existing E-Class.

The steering also feels slightly heavier, as though the level of assistance has been tuned for a touch more weight to add to the All-Terrain’s semi-SUV aura. If our perception is correct, it only adds to the sense of substance from the driver’s seat.

Its overall composure is maintained on dirt too, with the All-Terrain’s Victorian launch route offering a good dose of gravel and muddy unsealed roads. The all-wheel drive system keeps you pointing where you want and enables clean acceleration from the greasiest of corners. All of this highlights the All-Terrain’s potential as a ski field chaser.

We also detoured via some moderate fire trails, which gave us the chance to try the All-Terrain driving mode that lifts the suspension an extra 20mm and slackens the stability control and ABS to better suit low grip scenarios.

At speeds above 35km/h it reverts to Comfort mode, but will return to All-Terrain settings if you slow down again. In Sport mode or above 125km/h, the suspension lowers 15mm below normal to reduce aerodynamic drag. Even at full height it won’t challenge a GLE for clearance, but it’s significantly more capable than regular E-Class models.

Like all versions of the current E-Class, the All-Terrain carries the maximum five star ANCAP and EuroNCAP safety ratings. A brilliantly integrated suite of active and passive safety features represents the forefront of occupant and pedestrian protection, which goes well beyond its AEB, nine-airbag count, 360-degree parking cameras, rear cross-traffic alerts, and a pedestrian-protecting active bonnet.

These systems work in harmony to enable semi-autonomous driving, which is perhaps the greatest technical advancement of cars since we stopped riding horses.

Lexus now offers a five-year, unlimited kilometre warranty with roadside assistance.

Furthermore, NX 350h hybrid and NX 450h+ plug-in hybrid models also feature a 10-year, unlimited kilometre battery warranty.

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

The NX also includes three years and 45,000km of capped-price servicing, with each one costing owners just $495 – and that's highly competitive pricing for a luxury brand.

Plus, there's also Lexus' 'Encore' aftersales subscription program offering myriad offers and services.

The E220 d All-Terrain is covered by Mercedes’ three-year, unlimited kilometre warranty, with service intervals pegged at either 12 months or a generous 25,000km.

Mercedes is yet to confirm capped service pricing for Australia, but we don’t expect the All-Terrain to stray too far from the $556, $1112 and $1112 figures applied to the E220 d sedan’s first three services.
