Mercedes-Benz EQ-Class vs Smart 3

What's the difference?

When I was telling my colleagues about the Mercedes-Benz EQC my summary was, basically, it’s the best electric luxury car I’ve driven. 

It’s plusher than a Jaguar i-Pace, more polished than a Tesla Model X - indeed, it feels like a different kind of electric car to both of those models. It’s an impressive foray into the segment, and we can’t wait for the chance to put it against some like-minded electric European luxury SUVs at some point in the future.

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.

The Mercedes-Benz EQC is entirely different to what we expect from the brand, but it’s really what we expected all along when it came to an electric SUV from the Daimler stable.

It is sleek, streamlined and smooth, with panels that almost look like they’re formed from liquid. And it has the eco-edgy graphics you’d expect, with a specific grille treatment (yes, a real grille), headlights that are unlike any other Benz (they even have an LED that runs the width of the grille), and a rear-end style that looks almost like it was penned with another Stuttgart-based brand in mind… Porsche. I’m talking about Porsche.

But one thing that I really love about the EQC is its moustache. It's more prominent when the car is finished in white paint, but there’s a moustache that former Daimler chief Dieter Zetsche himself could be envious of. And he had one helluva soup strainer.

It is clearly made to be slippery, despite essentially sharing its underpinnings with the more conventionally angular - yet still rounded-edged - GLC SUV.

While it is a nicely styled gizmo, I found there are some things that could be annoying.

For instance, I was trying to plug in at night in a dark area, and while there is a small light above the charge port, other EVs have a light that actually illuminates the area where you’re plugging in. 

And also, the plug port is on the driver’s side. If, like me, you had to charge up with the car on the street, it just adds a little bit more anxiety to the whole situation. I shudder to think what could happen if the charger was hit by a passing car - folding the mirrors in is one thing, but you can’t fold the power cable! The lead for the charger is long, thankfully. 

I know, most people (maybe even all people!) who buy and EQC are going to have undercover parking in a garage or carport, but it’s still worth remembering that the filler isn’t on the kerb side like a number of other EVs. 

It has almost identical dimensions to that car: 4774mm long on a 2873mm wheelbase, with a width of 1884mm and a height of 1622mm. For context, GLC is 4669mm long, same wheelbase, a bit wider (1890mm) and just a little more height (1639mm).

What about interior design? Well it’s also familiarly different, with a number of changes to the materials used but still the same tech and comfort you’d expect. Check out the interior images in the section below.

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.

If you’re thinking the EQC looks like a seven-seat SUV, you’re wrong. It’s a five-seater, with a decent sized boot, too.

The luggage capacity is 500 litres, which is decent for a car of this size, but bear in mind there is no spare wheel under the boot floor. 

Rear seat space is reasonably spacious for someone my size (182cm) sitting behind their own driving position, with decent knee and toe space. Headroom is not terrific, though, and anyone taller will need to watch their head as they get in and out of the car as the top sill eats into space quite a bit. 

Any middle-seat passengers might find the room a little less likeable, as the transmission tunnel intrudes quite a bit. Those with big feet might find shoehorning themselves in and out a bit of a challenge as the sills are quite large, and our car even had optional ($1200) “aluminium-look running boards with rubber studs” - side steps, essentially. They get in the way, too.

But if you’re just sitting two abreast in the back the seat comfort is really good, the trim quality is excellent, and there is a flip down armrest with the storage bin and pop out cupholders. There are rear air vents (no climate control adjustment in the back, though, and no USB charging either), and there are two map pockets, plus bottle holders in the doors. Up front you will find a mix of familiar elements if you’ve sat in any recent Benz model, but a few unique finishes and trim elements that might be new to you.

There’s a beautiful horizontal fin theme that runs around the cabin, as well as the now-traditionally audacious looking Burmester sound system speaker covers. They don’t quite gel with the aesthetic, to my eye. 

The dash-top material - “fine surface texture”, as Benz calls it - is unlike anything else we’ve seen from the brand, it’s kind of like a soft silky slippery fabric trim. While there are lovely copper trim elements that just add something visually entertaining and appealing to the space.

There is a large covered centre console bin with 2x USB-C charge points and there is an additional USB-C upfront next to the wireless phone charger. The Mercedes touchpad system that aligns with the MBUX media screen is reasonably easy to get used to, but being a Benz there are plenty of options for usability - the centre screen is a touch-capacitive unit, or you can use the steering wheel-mounted controller on the left side of the wheel to control the middle screen. The right thumb controller manages the driver info screen.

It was mostly very easily managed, although the menus did get stuck at times for me - mainly in the section around the energy consumption. Plus I tried the whole “Hey, Mercedes” command thing, and it failed on numerous occasions. 

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.

Though originally brought to market by Mercedes, Smart was never pitched as a premium brand, as it is now.

Back in the late ‘90s, Smart was an early attempt at better urban mobility. The ForTwo was a tad over 2.5 metres long by 1.5m wide and 1.5m tall.

Today, the #1 and #3 share their modular EV platform with Geely’s other small crossovers, including the Volvo EX30 and Zeekr X, while a stretched version underpins the related Polestar 4.

While the #1 starts from a sharp $54,900 (all prices are before on-road costs) for the Pro+, at the other end of the spectrum, the #3 Brabus flagship, with dual motors for all-wheel drive (AWD) and Porsche 911-style acceleration, will set you back $70,900.

Not bad, given it also includes a body kit, extra driving modes, beefier suspension, stronger brakes and retuned traction controls.

Now, that might sound steep against the growing choice of more-affordable EV alternatives out there, but consider that most of the cheaper ones are significantly slower, less sporty and/or not as highly equipped, including the Hyundai Kona Electric, Jeep Avenger and Mini Countryman.

The #3 Brabus’ fiercest foe, the bestselling Tesla Model Y in top Performance guise, is more powerful but costs $12K more and is slightly slower from 0-100km/h.

The $70K Volvo EX30 Twin Motor Performance Ultra costs $1K less and matches the Smart performance-wise as they share the same tech, but it’s considerably smaller.

Meanwhile, the closely-related Zeekr X is $6K cheaper but looks bizarre and is still largely unknown in Australia. At least Smart has that long-time Merc association to fall back on.

In fact, it is distributed by the latter’s biggest dealer group globally, LSH Automotive.

Speaking of which, how does the #3 Brabus stack up against the similar Mercedes EQA and other luxury EV rivals? The less-powerful Merc 250+ is $14K more, has less kit and is nowhere near as powerful. Same goes for BMW iX2, Lexus UX300e and Volvo C40 Recharge (alias EC40).

The #3 Brabus seems to be in a goldilocks zone of premium, performance EV SUVs. The most expensive Smart offers thoughtful value for money. For a change, the car actually lives up to its name.

Predictably, it’s also well stocked, with matrix LED headlights, electric heated/vented front seats, a 12.8-inch touchscreen, head-up display, 640W Beats audio, a foot-actuated powered tailgate, 360-degree camera views, the full advanced driver-assist safety enchilada, auto parking assist, 20-inch alloys and a panoramic glass roof.

Unfortunately, fitted on every Smart, that last one does not come with a factory built-in sunblock, which is completely unacceptable under our hot Australian sun. And no crossover or SUV should be without a spare wheel, either.

These are the #3’s only real deal-breakers.

The EQC has a power output of 300kW and it has 760Nm of torque, which is enough to see its claimed 0-100km/h acceleration pegged at just 5.1 seconds.

The EQC’s top speed is 180km/h (limited for the sake of the batteries), and it has an 80kWh lithium-ion battery pack.

It uses a pair of asynchronous motors - one front, one rear - and they can alternate to do what’s best in the situation - be it working in 2WD (RWD or FWD), or in AWD. 

If you’re thinking about an EQC as a towing option, the towing capacity is 750kg for an un-braked trailer and 1800kg for a braked trailer.

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.

With an 80kWh battery pack and a Type 2 CCS plug (up to AC 7.4kW / DC 110kW) the charge times vary pretty greatly depending on what output you’re powering up from.

Mercedes-Benz says a DC fast charging station should be able to replenish the battery bank in 1 hour 22 minutes (at a maximum of 110kW, though some Chargefox stations offer charge rates up to 350kW) while an AC charging station (like you’d find in car parks) or Mercedes-Benz’s own Wallbox system should take about 12 hours 13 minutes.

Charging from a regular household powerpoint is a last resort option. It is claimed to take 46 hours 40 minutes from empty to full (230-volt outlet, 10-amp/2.3kW). I plugged in to a powerpoint in my house and the car’s info display was stating it would take 9.5 hours to achieve the remaining 16 per cent of charge. It didn’t get to 100 per cent before I had to unplug, however.

My not-so-urban test drive loop commenced with 97 per cent of battery charge and an indicated range of 363km available. The idea was to get a feel for the “range vs reality” of the situation, so I did it in Comfort drive mode with the climate control active and no intent to either thrash the vehicle or baby it to save battery.

My drive ended with 36 per cent indicated charge remaining, after I’d covered 231.6km. That means, based on the car’s own algorithm, that it would have covered 315km before the battery was depleted, which is a long way short of the claimed 434km range.

The indicated energy consumption was 20.8kWh/100km, which is ‘thirsty’ for an EV. On our recent electric car comparison test, the most efficient of our EVs - the Hyundai Ioniq Electric - used just 13.0kWh/100km. Yes, I know the EQC is a lot heavier (2425kg kerb weight), but even the Tesla Model 3 was notably more efficient (18.5kWh/100km) than the EQC over very similar terrain and driving.

However, our testing saw us return an even better consumption rate than Mercedes-Benz’s claimed figure, which is 21.4kWh/100km.

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.

If you have a garage and a Wallbox connector, there’s no reason the Mercedes EQC couldn’t be a terrific option as a commuter, a second car, or even your primary vehicle. 

The thing with all electric cars is that it’s about settling into a rhythm. If you use the car to commute to work, maybe you can charge it there. Or you might have a solar array and charge at home.

No matter the situation, you’ll be getting a rather nice vehicle to live with, based on my week with the EQC.

It’s a plush car, that’s for sure. The silence it offers is truly relaxing, and there’s effortless torque to pull you away from a standstill. The way you can build pace to overtake, the rush of noise-free acceleration, is pretty astounding. Perhaps not as visceral as in a GLC 63 AMG, but it’s still an experience.

The steering is direct and doesn’t require much thought, though it does lack a little bit of feel. But it’s easy to predict and quick to respond, making for pleasant progress around town. It’s easy to park, as well, with a great surround view camera system, as well as front and rear parking sensors. And if you’re not confident, the car has semi-autonomous parking, too.

The brake pedal feel takes some acclimation, because it responds pretty well, but the action is hard to modulate at times. That is partly due to the brake regeneration system, which actively captures energy that would have otherwise been lost during braking. You can adjust the level of aggression of the regen brakes, too, by tapping either the up or down shift paddles. The most aggressive setting will almost pull you up to a halt from urban speed without any brake pressure required.

The suspension of the EQC feels more settled than the last GLC I drove, and that could be in part due to the extra weight and stiffness of the battery cell under the body. The centre of gravity feels low, and it feels stuck down to the road in most situations.

The ride is mostly fine, but with big 20-inch wheels and low profile tyres, it can jar on hard edges. I also noticed that it can feel a bit unsettled at higher speed, as the body moves around - from side to side - more than I would have expected. It deals well with undulation changes and big dips, and if the surface is good, so are the comfort levels in the cabin. 

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 #3 range scores a maximum five-star ANCAP crash-test safety rating. It managed high-80s to 90 per cent in all disciplines – Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User and Safety Assist systems.

A full suite of ADAS is fitted, from Autonomous Emergency Braking (operable from 5.0-150km/h car-to-car) with junction, cross-path, pedestrian, cyclist and motorcyclist detection (5.0-85km/h), lane-keep assist (from 65-180km/h) and cross-traffic alert (front and rear), to blind-spot warning and traffic-sign recognition tech.

You’ll also find adaptive cruise control (with stop/go function), highway and traffic jam assist, automatic parking assist, front and rear parking sensors, 360-degree camera and adaptive high beam assist.

Included, too, are seven airbags (dual front, side chest, side head and front-centre), along with two ISOFIX child-seat fixtures and child-seat anchorage points in the back seat.

It mightn’t have the same method of propulsion as a petrol or diesel Merc, but it has similar service requirements. You still need to take it to the workshop for maintenance every 12 months - or every 25,000km! - whichever comes first.

Owners can either pay as they go for servicing, or pay up front and bundle it into their finance. The upfront rate is $1350 for three years/75,000km. Pay as you go will peg you along at $450 (year one), $750 (year two), $450 (year three). 

When the EQC launched it came with a three-year/unlimited kilometre warranty plan, but that was recently updated to a five-year/unlimited km plan, bringing Benz inline with the likes of Korean luxury maker Genesis, not to mention the majority of mainstream car brands.

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.
