Lexus NX vs Mercedes-Benz A-Class

What's the difference?

So, is the cheapest Lexus NX the grade you’d skip? Depends on where you live and drive.

If you’re urban based and bound, save up a bit more and go the petrol-electric hybrid; otherwise, out on country roads especially, the spirited and sporty NX 250 is more than up to the task.

Either way, though, the latest NX is finally fit to fight the other premium brands’ medium SUV efforts, head on and held up high. Welcome to big mid league, Lexus.

Ignore or underestimate at your own peril, everybody else.

The new AMG C 43 may lack the drama and excitement we’ve come to expect from the German performance brand, but that doesn’t mean it’s a bad car. Yes, it could be more extroverted and the ride could be improved, but this is still a sharp-looking sports sedan with loads of punch.

This is a car that speaks to its times, with ever-stricter emissions regulations making it harder and harder for car companies to produce loud, wild and charismatic cars. So Mercedes-AMG has worked within those boundaries and come up with a car that retains at least some of those core elements that has made the brand so desirable over the years.

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

Lexus says that nearly one million of the original-shape NX versions were produced, so there’s no way that the brand was going to mess with the styling of the latest version. Which explains why picking new from old is a serious case of trainspotting.

But that migration to the TNGA GA-K platform has brought some benefits from a design point of view. The styling now breathes more, especially when viewed rear-on, thanks to a body that’s 20mm longer and wider, as well as a handy 30mm wheelbase stretch.

Drilling into the details, the headlights have an LED ‘tick’ motif, the corporate ‘spindle’ grille isn’t as in your face and the rear gains ‘LEXUS’ lettering spelled out, probably to accentuate stance.

Crisp and elegant, the design works well. This is a handsome machine. Looks expensive too.

Mercedes has created something of a problem for itself with its decision to introduce AMG styling packages for the majority of its range, including the C-Class.

It means the C 43 has to walk a fine line between looking like a unique AMG model, rather than just a C300 with a bodykit and not out-doing the C63.

To that end it has AMG’s now familiar grille with vertical bars, the unique and complex-looking 20-inch alloy rims and a small lip spoiler on the boot. But otherwise it is surprisingly understated for an AMG, lacking the more obvious and muscular stance of previous AMG offerings.

Inside, there’s a similar theme, with the typical Mercedes-Benz luxury appointments but with a sportier, AMG twist. The steering wheel is chunky and comes with AMG branding, metallic shift paddles and a pair of rotary dials/buttons that allow you to alter the various drive modes and settings.

The one on the right allows you to switch between the pre-set Comfort, Sport, Sport+ and Individual modes, while the one on the left can scroll between the various individual aspects to tailor the settings to the conditions.

In typical modern fashion the design is tech-laden, with a digital display for the instrument panel (that can be switched between various graphics) and a large, tablet-style central multimedia touchscreen that controls the majority of the car’s non-driving functions.

Though distinctively attractive and obviously well built, the previous NX was quite small for a medium-sized SUV inside, with tight rear legroom.

It also had a nonsense mouse-operated multimedia controller that was fiddly, annoying and counter-intuitive to use.

Thankfully, the new-from-the-ground-up design has rectified both these issues in the latest version.

Now the NX is properly medium-sized, and so easier to get in and out of, as well as palpably roomier front and rear. Employing the RAV4’s TNGA architecture results in a lower and roomier cabin, that benefits all in terms of packaging.

Being the entry-level 250, you might not expect much in terms of interior presentation or style, but Lexus Australia’s product planners have been deft in specifying this grade to make it look luxurious and on-brand.

Body-hugging bolstered perforated leather front bucket seats, in our example finished in a black/cream hue with orange stitching, belie the base-grade reality of the 250. This scheme is also found on the centre console, armrest and door cards, lifting the ambience no end. It looks, feels and smells expensive in here.

The only thing that seems to be missing is a smartphone charger. That's part of a $3K option pack that also throws in a sunroof and foot-operated actuation for the electric tailgate. Not bad.

Then there’s the driving position, with an electrically-operated reach/height adjustable steering column and a multi-configurable seat to help find the right spot. All-round vision is also better than you might expect, no doubt helped out by huge exterior mirrors and a large reversing camera screen.

Typical Lexus-style classy digital instrumentation, directly ahead, are positioned in such a way that you’re not really aware of/missing the available head-up display in higher grades. Though it takes a quick amount of familiarisation, all the info there is ultimately clear and easy to take in.

The same applies to the now touch-only centre screen, which has a slick rich finish and tactility, and also encompasses the climate-control display.

Along with banishing the dreaded mouse pad, kudos to Lexus for also installing physical switches or buttons for the most-used items – audio volume, temperature setting, and front and rear window demisting.

These and the simplified sub-screen menus for navigation, wireless telephony/audio streaming, vehicle diagnoses and vehicle settings amongst other features, is quickly second-nature in their accessibility and operation. And the sound system quality is great too.  

One of our very few complaints concerns the Apple CarPlay experience, which seems needlessly complicated to return to if you temporarily switch away from it to the NX’s native multimedia system. Confusing and distracting. 

Never mind. There are minivan levels of practicality at work here, from the superb and easily manipulated ventilation system to the seemingly endless storage options, that include bottle holder capability in the doors, a clever lid operation for the huge centre console and properly engineered cupholders.

Lovely lush materials of satisfying quality are further plus points.

We’re also fans of the NX’s electric door opening system with a failsafe handle, meaning you can grasp the door handle inside or out and a solenoid activated by a press in of a thumb releases the door quickly and naturally in a single action; it feels… upmarket and ergonomic once accustomed to.

Accessing the back seat is easy due to the latest model’s larger proportions. Much of the same applies out back as the front seat area in terms of quality of finish and attention to detail. Sculptured and enveloping backrests (adjustable for two reclining positions), a well-padded cushion and more-than-sufficient space for two burly adults or three smaller people means this NX is more family friendly than the swoopy exterior styling suggests.

We’re also happy to find large people-facing air vents, two USB and a 12V outlets, one-touch electric windows with that premium-car soft close mechanism, overhead LED lights, grab handles, centre armrest with cupholders, map storage behind both front seats, coat hooks and good lines of vision further enhance the appealing and comfortable back seat environment. It feels like a Lexus should.

Further back than that, after releasing the electric tailgate via either an interior button or exterior switch, you’ll find that the boot has a fairly high loading lip, but then offsets this with a long, flat floor with matching levels of appropriate-quality finishes. Another 12V plug and two bag hooks are included, along with ample lighting and tie-down hooks. There’s also a hidden deep storage compartment underneath the floor, due to the discontinuation of a spare wheel (due to runflat tyres, remember).

Capacity is rated at a fairly ordinary 520 litres, extending to 1411L with the split/fold backrests folded. You’d expect a remote actuation for the latter like Mazda wagons have had for decades, but none is found at this price point.

Note there is no solid cargo cover either, just a flexible/flimsy fabric item that’s foldable and easily stored.

Overall, though, despite of its base positioning within the NX hierarchy, the 250's interior experience is in keeping with the brand's image.

The new C-Class has grown slightly in size compared to the model it replaces, most notably with a 26mm increase in the wheelbase which you can feel in the cabin.

The front seat space is good, with excellent adjustability for the power-adjustable seats and steering column. I had no trouble finding my ideal seating position which makes for a more enjoyable and uncompromised driving experience.

Rear space is a bit tighter (which is typical for this segment/size of vehicle), but thankfully the standard seats do have very deep sculpting in the backs which allow for more knee space and foot room.

However, at approximately 180cm (six-foot), I wouldn’t like to sit behind my seating position for long periods as my knees were touching the seat back, and headroom is compromised with the panoramic glass roof.

In terms of small item storage there’s a lidded console box in between the front seats as well as a pair of cupholders and a small tray where you can place your mobile phone.

It’s worth noting, though, that early examples of the C 43 in Australia do not have a wireless smartphone charging pad, with that reportedly being introduced from February production.

While that’s good news, it’s not really competitive in this day and age to offer a car costing six-figures without such technology.

There’s also only a single USB-C power outlet in the front, which is another disappointment, but there is a pair in the back.

Mercedes does win some points back for a respectable 455-litre boot, which has a nice wide load opening that will make packing luggage easier.

We’ll get to the major change under the bonnet shortly, but another significant alteration for this latest C 43 is the price.

It now starts at $134,900 (plus on-road costs), which pushes it well above its market rivals, the BMW M340i xDrive and Audi S4, which start at $104,900 and $106,200, respectively.

However, Mercedes has added more technology under the bonnet and loaded the C 43 up with standard equipment, including its '4Matic' all-wheel drive system, adaptive damping, rear-wheel steering and 20-inch alloy wheels.

In terms of creature comforts, the C 43 is well-appointed, with leather upholstery, a head-up display, augmented reality navigation, a panoramic sliding sunroof, and a Burmester 3D surround sound system.

There are two option packages for the C 43. The 'Digital Light Package' costs $2400 and adds Multibeam LED headlights with 'Ultra Range' highbeam, 'Adaptive Highbeam Assist Plus' as well as active light function and cornering light function.

The 'Performance Ergonomics Package' includes AMG Performance front seats, an AMG Performance steering wheel in Nappa leather and microfibre and the 'AMG Track Pace' system for an additional $5200.

There are two ways of looking at this.

Yes, the NX 250 is powered by a variation of the same engine found in the humble base Camry Ascent in Australia at almost half the price. On the other hand, it’s a Toyota powertrain and everything that’s good and reliable and dependable about that. Which is not always the case with premium SUVs.

Dubbed Dynamic Force, which may imply forced-induction like a turbo or supercharger but there isn’t any, the 2487cc 2.5-litre naturally aspirated direct-injection D-4S twin-cam four-cylinder engine delivers 152kW of power at 6600rpm and 243Nm of torque at between 4000rpm to 5000rpm.

Drive is sent to the front wheels only, via an eight-speed torque-converter automatic. Tipping the scales at a pretty hefty 1705kg, it’s nonetheless the lightest NX, and manages a power-to-weight ratio of 89.1kW per tonne. That’s about the same as a GLC 200, which uses a 2.0-litre turbo petrol engine.

The biggest talking point about this new car is the engine, with AMG downsizing from the old C 43’s six-cylinder to a 2.0-litre four-cylinder turbocharged petrol engine.

But it’s not just any turbocharged four-pot, because it is fitted with technology that Mercedes claims has been inspired directly from its Formula One team.

While the F1 team engine facility is based in England, this engine was designed and developed by the Mercedes-AMG team at its Affalterbach headquarters, but the concept of the electric turbocharger reportedly comes from the engine that powered Lewis Hamilton to multiple world championships.

The electric exhaust gas turbocharger - to give it its official name - uses a small electric motor on the turbocharger shaft to spin up the blades without having to wait for any exhaust gases to pass through it first.

To power the electric turbo the C 43 is equipped with a mild-hybrid 48-volt electrical system.

Mercedes claims this means reduced lag and improved throttle response for a sportier driving experience. 

It also helps make this small engine produce big amounts of performance, with AMG extracting 300kW of power and 500Nm of torque from this 2.0-litre, which is more power than the previous six-cylinder C 43 managed.

The engine is paired to a nine-speed multi-clutch transmission, which isn’t a dual-clutch with a pair of clutches operating on every second gear ratio, but instead uses a “wet start-off clutch” for better take-offs and smoother shifting on the move (at least in theory).

Power is sent to the road via all four wheels thanks to Mercedes’ 4Matic all-wheel drive system.

Rated Euro6b, the NX 250 demands 95 RON premium unleaded petrol. Same as Camry, actually,

We recorded a decent 9.7 litres per 100km during our time using the NX 250 in city, urban and rural conditions, against the trip computer’s 9.5L/100km and the official combined average of just 6.9L/100km.

Note this may be so because there was a lot of fast back-road driving, as the engine loves a rev and there’s a palpable wave of power that comes on strongly between 5000rpm and 6500rpm. A bit like Mazda’s naturally-aspirated units, but just not as sonorous.

At 55 litres, the fuel tank will allow for up to 797km based on the combined average cycle between refills.

Despite the smaller engine you can hardly call the C 43 miserly, with a claimed combined urban/highway cycle rating of 9.1-litres per 100km. That’s only a 0.2L/100km improvement over the old six-cylinder.

On test, which included a return trip from Sydney to Bathurst via motorways and some dynamic back road driving, we saw a return of 11.8L/100km on the car's onboard computer.

While hardly hybrid-worrying, it’s impressive to think that driven modestly, such a potent engine can return a single-digit fuel figure.

The NX 250 truly is a tale of two cars.

Around town, it is utterly capable and benign. The 2.5-litre atmo four-pot petrol unit is a revvy, raucous sort of engine, pulling away strongly off the line, responding quickly to pressing down on the throttle, shuffling up through seven of the lower gears smoothly (top is a highway overdrive), and generally being an easy vehicle to drive.

About the only concern is how noisy the engine can become if you’re needing to accelerate hard, with a definite mechanical zing that gives the Lexus a bit of a hoon attitude. We’re also a little hesitant about using the Sport mode in built-up areas, as ratios are held on to whether up or down shifting, amplifying the loud nature of this powertrain.

Other aspects of the NX 250’s driveability around town rate highly: light yet linear steering, with a tight turning circle providing easy manoeuvrability and parking; firm yet still absorbent suspension, offering an appropriately isolating ride over most bad road surfaces; and an overall sense of sound engineering. It seems quieter than an equivalent RAV4, more importantly.

Which led us to initially conclude that, in an urban environment, you’d naturally pay the extra $3K for the NX 250 Hybrid, to eliminate that noisy engine when pushing down hard on the throttle. Easy.

However, then we ventured out on a long rural drive, a few couple of hundred kilometres from the big city. On country roads, the NX 250 really sparks up in a most compelling way.

Yes, the engine is still a bit rowdy, but as the revs rise and the needle edges near the 6800rpm red line, the Lexus just keeps on building up speed rapidly, providing an unexpectedly sporty edge. Above 5000rpm this thing still has plenty of oomph, relying on a deep well of power to really extend its legs.

It also makes sense to slot the auto lever into manual, and use the finely positioned paddle shifters. That’s when you’re most aware of the gearbox being a torque-converter auto, with defined and assertive selections. It’s a good way to feel involved in the experience too.

Actually, as a mechanical ensemble, it all comes together at speed; that light and easy steering remains relaxed yet reactive, weighing up nicely if you choose Sport. The handling maintains a fluid, connected feel, with ample levels of grip from the Bridgestone tyres.

It occurred to us that driving the NX 250 Hybrid out on rural backroads would deny the enthusiast of the base model’s lightness and agility, since the latter weighs hundreds of kilos less; the brakes are perfectly modulated instead of feeling vaguely mushy and/or trigger happy as with many electrified SUVs; and – even with the road noise being well-supressed – you’re far less aware that the atmo petrol engine is singing loudly at speed.

Plus, the ride out in the sticks, even on our craggy old test strip that would jar the bones of some other midsized SUVs, remains calm and comfortably firm. That’s real progress for the NX.

We’d appreciate a bit more nuance in the way the stability control kicks in (quite late) to catch the tail; while the driver-assist tech like the adaptive cruise control and lane-keep assist do their jobs admirably, the latter’s constant chiming can be annoying; and there's a fair amount of road-noise intrusion over coarse bitumen. Like most midsized luxury SUVs, actually. Still quieter than a RAV4, though.

No jarring faults then. Lexus has done its homework and fixed most of the things that annoyed or infuriated us about the previous generation version. Good work.

Let’s start with the good news. The new Mercedes-AMG C 43 is a quick car. The engine may be small in size but the electric turbocharger does its thing and provides plenty of punch.

You can get a performance boost, too, thanks to the belt-driven starter generator, which acts as a mild hybrid and gives you a surge of 10kW for a brief period if you need a sudden burst of extra speed.

The chassis is well-sorted, too, at least from a dynamic point-of-view. The rear-wheel steering can provide up to 2.5 degrees of turning, which improves handling at speed and manoeuvrability when parking.

However, there are some less-impressive elements to the C 43, too. The obvious one is the drama, or rather the lack thereof.

As I said at the beginning, the C 43 has never been as wild or raucous as the V8-powered C 63, but when you buy an AMG there’s a rightful expectation that it will provide some thrills.

The C 43 simply doesn’t have that character about it. Yes, it’s fast, but it produces that speed with efficiency rather than excitement.

And it’s not an engine size problem, because even the 2.0-litre four-cylinder A 35 and CLA 35 offer more ‘wow factor’ than the C 43.

Yes, the engine makes noise under acceleration (and it can be altered between discreet and sporty) but even at its best it sounds muted and lacks the evocative tone of a V8 or six-cylinder engine. 

Another disappointment is the transmission calibration, with the gearbox awkwardly shifting out of first gear on multiple occasions during our test drive.

In the taller gears it felt smooth enough cruising along, but given its low speed shifts we’d like to spend more time in the urban environment before passing final judgement. 

The other notable element of the driving experience we struggled with was the ride quality. While fine on the smoother motorways, our test drive included time on some patchy country back roads and the C 43, even in the ‘Comfort’ suspension setting, was simply too firm.

Riding on low profile tyres, the adaptive dampers struggled to isolate the cabin from the imperfections in the road, leading to a fussy ride at times.

Overall the C 43 is a good car, but it feels like there are still some areas where Mercedes could improve it to make it really live up to the AMG badge.

The C43 gets a comprehensive list of safety equipment that leaves little out. Obviously there are the usual passive safety items, like 10 airbags, including dual-front combined pelvic/thorax airbags and a front centre bag that drops between the front seat passengers to minimise the chances of a head clash.

Also included as standard is autonomous emergency braking front and rear (covering speeds between 7.0-200km/h), adaptive cruise control with active stop/go, a 360-degree parking camera, 'Active Parking Assist', 'Active Lane Keeping Assist', 'Blind Spot Assist' and, of course, anti-lock brakes with 'Brake Assist' and 'Adaptive Brakes' with Hold function and electronic stability control.

Also included are dusk-sensing LED lights, rain-sensing wipers and run-flat tyres with tyre pressure warning.

The C43 also comes equipped with Mercedes’ 'Driving Assistance Package Plus', which adds even more safety gear. This includes 'Active Blind Spot Assist', 'Active Brake Assist with Cross-Traffic Function', 'Active Emergency Stop Assist', 'Active Lane Change Assist', 'Active Lane Keeping Assist', 'Active Steering Assist', and 'Active Stop-and-Go Assist'.

While the C43 hasn’t been specifically crash-tested, the latest C-Class was rated by ANCAP with a five-star score for all models except the upcoming C 63 S E Performance.

Since the beginning of 2021, Lexus offers a five-year, unlimited kilometre warranty with roadside assistance. It used to be four years.

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 $495 – and as we’ve noticed in the recent past, that is very highly competitive pricing for a luxury brand.

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

The C 43 is covered by Mercedes’ five-year, unlimited kilometre warranty, which has become the new standard for the luxury car market.

Service intervals for the car are at 12 months/25,000km, which is on par with industry standard.

Mercedes-Benz Australia will offer a service plan for the C 43, prices were yet to be confirmed at the time of publication but the company has indicated it will be similar to the C300. 

That means $550 for year one, $900 for year two, the third service costs $1000 and the fourth year service costs $2450 - for a total of $4900 for the first four years of ownership.
