Smart 3 vs Zeekr 7X

What's the difference?

The #3 Brabus is very nearly one of the great bargains of 2024, with the sort of style, luxury, features, performance and grip you’d expect from the much-more-expensive GLA AMG 45. It’s that good.

What would make it great is a sunblock for the hot glass roof on a sunny day, Australian road tuning for the infuriating ADAS tech and a revised steering tune that didn’t make it feel inconsistent at times.

See past these, though, and the #3 Brabus exceeds expectations.

We’re glad Smart is back.

Not the most comprehensive of tests, I'm afraid. But early signs are good for the Zeekr 7X, which ticks plenty of on-paper boxes, looks sleek and fresh and feels sorted from behind the wheel.

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

Smart says Mercedes designed the #3 and it shows.

In silhouette, or when glanced peripherally, it could be the love child of the A-Class and EQA. Only the friendly face betrays its non-Benz heritage.

Longer and wider than the #1, it is also 80mm lower – achieved via a lower ride height, flatter seats and a thinner floor.

Helped by a 35mm wheelbase stretch, it provides a nicely-balanced and proportioned crossover, with a decent drag coefficient of 0.27. The Brabus’ big wheels also fill out the arches very nicely.

Key length/width/height/wheelbase dimensions are 4400mm/1844mm/1556mm and 2785mm, respectively.

Unusually for a coupe/crossover mash-up, there’s slightly more room inside compared to the upright donor model.

Let’s take a longer look in there.

It’s a sleek-looking SUV, the 7X, and is nowhere near as boundary-pushing as its stablemate sibling, the Polestar 4, which rides on the same platform. For one, the Zeekr has a rear windscreen.

Zeekr calls it 'hidden energy' design language, which I take to mean, at least partly, that you can’t immediately tell what’s powering it. It could pass as an internal-combustion car, a hybrid, PHEV or EV; at least until you look closely.

There are light bars front and back, but sadly we miss out on what the brand calls its 'Light Curtain' - a pixel-filled bar of light that spans the entire front end. Apparently it fell victim to the ANCAP crash-test requirements and has been replaced by a black cover.

Even without it, I dig the 7X’s athletic stance. It looks good in the metal, especially finished in deep green paint.

Inside, it’s a pretty plush-feeling cabin, without being revolutionary, and the big central screen and digital dash are bright and clear. The addition of a camera to monitor back seat passengers without having to turn around is a clever touch, too.

On first approach, you ask yourself whether the #3 is a crossover or a small-to-medium SUV. The low roof and cool frameless doors certainly suggest the former, as do the comparatively small apertures.

That said, with the windows down, those sash-less doors help entry and egress.

Once ensconced inside a long if slightly narrow cabin, the #3 offers ample room for even the tallest adults up front, as well as a reasonably spacious back seat area, though you’d call that more of a '2+1' seater given the lack of girth for three. Most folk shouldn’t struggle to find the right driving position, either.

Presumably keen to impart a generic Mercedes vibe, the #3’s interior is somewhat reminiscent of a GLA’s, albeit from last decade – down to the pronounced T-shape dash featuring a trio of circular vents in the middle, a standalone screen above and (unconvincing) metal-look plastic trim below.

Understandably, like so much of the Brabus, this might appeal to aspiring A45 AMG owners, but it seems oddly dated, given the advanced electrification going on underneath.

Likewise, none of the minimalism cleverness of the ForTwo city-car original is referenced, even digitally. A lost opportunity, really. The OG Smart is an icon.

Meanwhile, ahead of the driver, a narrow digital strip looks twee and cheap, as if ripped from a Japanese 'Kei' car. It’s a strange design detail for a $71K SUV.

Still, the #3’s cabin layout is largely a success, and much of that is due to the first-class quality and finish. Unlike some of the aforementioned Benzes of the previous decade, squeaks and rattles are notable by their absence.

Depending on your body, the racy sports seats up front are either perfectly bolstered or far-too snug, but they provide a decent level of comfort and support. And they position you just right for controlling the centre display, which dominates all.

The 12.8-inch touchscreen feels slick, responsive and right-sized for the car. At first, it can also seem like info-overload and perhaps a bit cheesy with its animal animations, but real thought has gone into it to provide an extraordinary level of functionality.

Across the top are icons for access to media, sat-nav, apps and camera view settings, while the bottom row is for various climate and trip info. While somewhat logically presented, the charging-station list seemed outdated and/or at-times incorrect in our test car.

Mercifully, the Smart has a row of short-cut buttons for 'Vehicle Modes' (including turning off the infernal lane assist and one-pedal accelerator/braking), 'Driving Mode' ('Eco'/'Comfort'/'Sport'/'Brabus'), glass demisters, climate and display-off.

Annoyingly, the latter is closest to reach, revealing the #3’s left-hand drive market bias, as the driver must stretch across to access the first two (and more important) settings.

There are also several handy screen-activated modes including 'Entertainment Mode' that temporarily leaves the accessories and climate control on; 'Rest Mode' reclines the driver’s seat down flat and dims the interior lights; 'Energise Mode' is designed to pep you up; and 'Pet Mode' keeps a climate-controlled atmosphere while deactivating all buttons that a stray paw might press. Clever.

There’s lots more besides, and using the touchscreen is better in this than most other Chinese vehicles, but it remains fiddly and distracting.

It’s also worth pointing out that the fixed glass roof needs a blockout for Australia. A Smart spokesperson said an aftermarket cover is available, but as supplied to us, sitting under it over a run of hot days is almost unbearable without a hat. This is not good enough.

Thankfully, the other basics are all A-OK.

The climate system coped well the hot sun bearing down through the glass, plenty of useful storage makes up for the disappointingly shallow glove box, while the chilled centre console and massive door bins proved especially handy.

USB access is easy, the wireless Bluetooth/Apple CarPlay performed more consistently than in any recent test vehicle and the standard Beats audio brings brilliant sound.

Out back, most people under 180cm should at least avoid scraping that glass ceiling, and there’s a reasonable amount of room for boots and long knees if the front occupants are sympathetic, but you’d be stretching the truth calling the rear seat packaging SUV-esque.

On the other hand, it’s beautifully presented, boasts a comfy and supportive backrest/cushion for outboard passengers and even a do-able centre pew for shorter-distance riders.

And it provides every expected amenity, including air vents, USB-C ports, door storage, a folding centre armrest with cupholders, and overhead handles/lighting/coat hooks.

And while we’ve already complained about the glass roof, it floods the cabin with light, to make it seem airier than it is. Narrow front seats with a see-through slit further enhance this feeling.

Further back, the 370-litre boot is reasonably long and surprisingly deep thanks to a removable upper floor that’s good for stuffing the optional home charging cables in.

And, of course, it can be extended to 1160L via the split-fold backrests to provide extra loading practicality. And there’s even a small (15L) amount of storage under the bonnet.

Maximum towing capacity is 1600kg for a braked trailer.

The 7X stretches 4787mm in length, 1930mm in width, 1650mm in height and rides on a 2900mm wheelbase.

As is pretty typical of electric SUVs, interior space is great, especially for backseat riders. I'm 175cm and have heaps of knee and headroom behind the driver's seat set to my position.

Storage space is good, too, with a deep bin between the front seats, a pull-down divider in the back row and pull-out draws beneath the back seat which mean you can hide laptops or valuables when you lock the car.

One key quirk, though, is the location of the USB charge ports in the back, which are accessed through the pulldown seat divider. It means that, should there be three passengers in the back, you won't be charging any devices.

The boot is 539 litres of flat, wide space – though that number grows when you drop the 60/40 split-folding back row. Rear-drive models also get a 62-litre 'frunk'.

There are three ways into the 7X, with two rear-drive models and one AWD Performance completing the trilogy.

That story begins with the 7X Rear-Drive, which gets the smallest battery and lists at $57,900, before on-road costs. Next is the Long-Range at $63,900, which is also a rear-drive model but nabs a bigger battery and a longer driving range.

Finally, the Performance is $72,900, and is the only twin-motor model. It scores the same 100kWh battery as the Long Range, but significantly ups the performance, which in turn dramatically lowers the zero to 100km/h time.

Standard kit is pretty impressive across the board, with the entry-level model scoring 19-inch alloys, LED lighting all around, a powered tailgate, a glass roof (with powered shade) and ambient interior lighting.

Tech is handled buy a 16-inch central touchscreen with Apple CarPlay and Android Auto and there are two 50W wireless charge pads. You also get a digital dash, tri-zone climate and a 10-speaker stereo.

The Long Range model adds a better 21-speaker stereo and a head-up display, while the flagship Performance gets trick auto-opening and closing doors (you just push a button in the pillar to open and step on the brake to close), as well as genuine Nappa leather trim, 21-inch alloys and very good adaptive air suspension.

The #3 Brabus employs one permanent magnet synchronous electric motor per axle, for dual-motor, all-wheel drive performance via a single-speed ‘transmission’. 

They provide plenty of poke, totalling 315kW of power (115kW front, 200kW rear) and 543Nm of torque (200Nm front, 343Nm rear).

Tipping the scales at 1910kg, this means the Brabus delivers an impressive power-to-weight ratio of 165kW/tonne – enough for it to scoot from zero to 100km/h in 3.7 seconds, on the way to a 180km/h top speed.

To put those figures in perspective, the similarly-priced VW Golf R only manages 156kW/tonne and 4.8sec to 100.

The two rear-drive ZX models share the same rear motor producing 310kW and 440Nm. Not stratospheric numbers but the powertrain delivers plenty of useable, real-world grunt, with both variants reporting a zero to 100km/h time of 6.0 seconds.

The AWD Performance model really ups the grunt, though, adding a second electric motor at the front axle lifting total outputs to 475kW and 710Nm and dropping the 0-100km/h run to a crazy-brisk 3.8 seconds. It’s also the only model to ride on the very good adaptive air suspension as standard.

All #3s headed to Australia for now are fitted with the larger of the two battery packs available – a 66kWh lithium nickel cobalt manganese (NCM) item.

In the Brabus, it is rated to average up to 415km of WLTP-certified range, which is between 20-40km shy of the mid-spec Premium version.

Smart says the WLTP average energy consumption is 17.7kWh/100km. Our 3000km-old test car’s trip computer displayed a life-cycle average of 14.6kWh/100km since delivery.

During our week with the Brabus, we managed an average of 19.4kWh/100km, and that was over a 95km period of sustained highway driving at 114km/h with cruise control on and climate control set at 18 degrees (to combat the radiant heat from that glass roof).

With a big 22kW AC charger and 150kW DC charger capability, the former will replenish that 66kWh battery in about 32 hours using a home plug or 10 hours with an optional 7.0kW Wallbox, while the latter will need just over an hour from 10-80 per cent with a common 50kW DC charger.

The cheapest 7X variant scores a 75kWh LFP battery, while the Long Range and Performance nab a 100kWh NCM unit. All have an 800V electronic architecture, allowing for mega charging speeds of up to 450kW DC charging (actually 420kW on the 100kW battery).

Now, I don’t think we have chargers capable of pushing that much juice in Australia, but even using our 350kW chargers Zeekr promises you’ll go from 10 to 80 percent charged in 16 minutes or less. AC charging is up to 22kW, too.

In terms of driving range, you can expect 480km in the rear-drive, 615km in the Long Range and 543km in the Performance, all on the WLTP cycle.

Whatever notions ‘Smart’ might evoke, the #3 Brabus obliterates them. This is no buzzy little city-car runabout, but a surprisingly mature and athletic driving machine. This is a seriously rapid performer.

A trio of driving modes give you a hint of what you’re in for. Eco is lightness and fluff. Not very Brabus, but smooth and calm enough for relaxed commuting. And it’s far from slow, scooting off the line with zip and zest. Enough for most.

Comfort is actually a good all-round setting to be in, with an eager yet controlled level of performance. Strong acceleration and instant accelerator reaction show you mean business – if you’re in the mood. Still civilised and serene otherwise.

Sport ups the ante, as you’d expect, providing a decent whack of speed and immediate response. Actually, this is enough to keep up with most sports car costing thrice the price, while maintaining the driver-assist safety net. Fun without the fear.

Brabus mode is off-the-leash fury, turning the #3 into a convincing AMG alternative thanks to blistering thrust and a powerful punch across the spectrum. More (artificial) noise, more drama, more speed, more fireworks. The 'Launch Control' pins you to your seatback.

Yet even in the latter setting, the Smart behaves with a maturity beyond the brand’s reputation, capable of quick corners with exceptional (AWD-enhanced) body control and roadholding grip, without a punishing ride.

Underneath, a unique suspension tune for the MacPherson-style struts up front and multi-link rear end keep the Brabus hunkered down more effectively at speed.

And even in pouring rain, there are no complaints about the Brabus’ assured and confident handling. Yes, the suspension is firm, but it’s far from uncomfortable, so, an acceptable trade-off.

Plus, though not strictly one-pedal driving, the regenerative braking pressure is enough for slowing down and speeding up in the ebb and flow of traffic in its strongest mode.

Where we’re less happy is in the #3’s steering. It brings three weight modes to the table – but only two are useful, 'Light' and 'Standard'. Super-easy yet not totally devoid of substance, Light is great for around town and general commuting.

But when you lean on it at speed, the steering, whilst crisp and reactive, is not always linear in feel or motion, especially when accelerating at the same time, as you might when coming out of a fast corner.

Depending on how hard you are on the accelerator, there can be a visible step when turned from the straight ahead that can be quite disconcerting. It’s a bit like when slurping in a lumpy bit in a smoothie.

So, what about 'Sport' mode? Here, the steering is just as described above, but with added weight and not much more. Not worth it. Best is Standard mode.

Another disappointment is the advanced driver-assist safety (ADAS) tech’s state of tune. It’s in a state, literally.

The intrusive and apparently non-permanently switch-off-able lane-keep systems, especially, end up resisting what the driver intends, and even fight to steer the car where it thinks it needs to be. This is frustrating and potentially dangerous.

It’s been reported that Geely, and not Mercedes, undertook the development of these ADAS systems. We’re getting sick of (mostly Chinese) manufacturers rolling the arm over and imposing this sort of nannying and ultimately counter-intuitive driving interference tech.

This needs to be fixed. It stops the #3 Brabus from being a great performance bargain.

The 7X is very much the vehicle Zeekr has been waiting for in Australia, so expectation weighs heavy on its metallic shoulders. Happily, and not to spoil the ending, it largely lives up to those expectations with our taste test revealing an electric SUV that shines in most areas.

Our drive experience took place at one of Australia’s longest and fastest race circuits, The Bend outside Adelaide. And not in the AWD Performance version, but in the less-powerful Long Range model. Not exactly the natural environment of a circa 2.5-tonne electric SUV, then.

And while the rear-drive Zeekr is no out-and-out performance car, the 310kW and 440Nm served up from that rear-axle motor is plenty to get the 7X up and moving, with the power arriving in a steady and unbroken stream that saw us pretty easily push to 200km/h on one of the track’s lengthier straights.

I’d argue that’s more than enough grunt to satisfy most, if not all, Zeekr owners without them having to dig deep for the Performance model. But there’s no escaping the fact this is a heavy vehicle, and one inspired by efficiency, not the red mist of racing.

So, things start to drop away a bit when the lesser 7X is really pushed, with an off-putting kind of buffeting movement at speed and sometimes spongey-feeling dynamics a reminder that this is a vehicle more at home on public roads.

The AWD Performance, however, sharpens things up considerably, helped by its adaptive air suspension and all-paw grip. It feels far tighter, grippier and more composed through corners. Sadly, by the time I jumped in, my lead-footed colleagues had drained the battery to the point where I could only accelerate at 50 per cent capacity, which made the AWD slower on the straights than then RWD model, but it made up plenty of lost ground in the way it corners.

All of this is, of course, is likely to be of little relevance to any 7X customers, who are more likely to find themselves on the moon than they are the main straight of a race track, and so my opinion hasn’t changed — the AWD is faster and more technically advanced, but when you boil it down to the actual life a mid-size electric SUV will live, I think the smart money is on the Long Range AWD model.

Side note: We also did some pretty serious off-roading (again, something no owner is likely to do) in the AWD model, and I can report that the softest suspension, steering and accelerator settings add a cosseting comfort to the drive experience on rough roads, and that there is some genuine of-road capability on board.

How it drives on actual roads? For that, you’ll have to wait just a little longer. But early signs are good for Zeekr’s most important model.

The 7X wears a maximum five-star Euro NCAP assessment and I want to point out a pretty wild feature. Standard across all trims is a high-def camera in the B-pillar aimed at the rear seats. You can cover it, if you’d like, but the idea is that anyone up front can hit a button near the central screen that will pull up a high-def feed of what’s happening in the back seat. So, no more having to turn around to see what the kids are up to in the back seat.

Happily, all 7X models get the same safety suite, which includes a 360-degree camera, autonomous parking and 15 ADAS functions.

The #3 offers a (decidedly-average) five-year or (disappointing) 130,000km warranty, whichever comes first. There is also roadside assistance available for free during this period.

Given other EV manufacturers are going seven and even 10 years in the case of MG, with most including unlimited kilometres, this could be better.

Scheduled maintenance is every 12 months or every 20,000km.

Smart provides a pre-paid four-year/80,000km service plan for $3120, which comes to $780 annually. This seems quite expensive for an EV, even a premium one.

The Zeekr 7X is covered by a five-year, unlimited-kilometre warranty, while the battery is covered for eight years or 160,000km. There’s five years' roadside assistance thrown in, too.

Servicing is recommended every two years or 40,000km, with what the brand describes as optional health checks in years one, three and five (the first one's on the house).

Go for all the services, including the optional ones, and you’re looking at $2415 over the first five years. Skip the optional ones, and it’s more like $1755.
