Smart 3 vs Audi Q3

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.

So is this new Q3 good enough to remain Audi’s number one choice? In a word, yes.

Audi has resisted the temptation that some brands fall into by making too many changes to a proven sales performer. This new Q3 isn’t radically different from the old Q3, but it has improved in almost every way.

It isn’t different enough to widely expand its appeal to a new wave of customers, but there’s no reason it won’t remain Audi’s most popular choice for the foreseeable future.

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.

The brief to the designers was seemingly pretty simple - don’t mess with a good thing.

According to the company, they want it to be recognisable as an Audi from 100m away, but at the same time, it makes sense not to make any radical changes to a design that is clearly a hit with buyers.

There’s still a new grille, which is slightly larger, while the daytime running lights (DRLs) are now mounted high, on the top corners of the front fascia.

Audi prides itself on its lights and the Q3 features multi-segment DRLS, with dynamic light effects, plus the rear badge lights up red with the tail-lights are turned on.

Digital matrix LEDs are available as an option on the quattro grades, which is a first for such a small Audi. While based on the technology already deployed in the bigger, more expensive Audi models, this is an updated system with micro LED matrix capabilities that are better able to light up the road ahead without blinding cars ahead or oncoming.

One very noticeable element to the design of this new Q3 is the size - which hasn’t really changed. Audi has resisted the temptation that so many brands have to upsize a compact model and has instead retained the same size that buyers clearly find appealing. It is slightly longer, approximately 4cm, but is still unmistakably a Q3 in looks and size.

Inside the Q3 is a different story, with the designers clearly empowered to create more change. The elements remain similar, but there have been more dramatic changes compared to the exterior to keep the Q3 looking contemporary and luxurious.

For example, there are still two large screens, just like the old model, but the virtual cockpit and multimedia screen are integrated into the dashboard together and more prominently, moving higher up the centre fascia.

It works well, as the interior looks and feels premium, and very much an Audi, albeit on a smaller scale.

To cap it off there are four interior colour packages to choose from, plus four different choices for the inlays, including two real wood options and an aluminium trim.

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 biggest change to the interior is the technology, with a new multimedia interface with new, larger tiles as well as new ‘Control Unit’ for the key driving functions.

The ‘Virtual Cockpit’ display is much simpler, with a nice, clean look, plus the option to have the satellite image on the screen, whether you’re in navigation or not. The multimedia screen is a good size (12.8 inches) and the menus are easy to navigate. The decision not to have physical controls for the climate control is disappointing, but thankfully there is a volume/on-off dial for the sound system.

The most notable difference is the so-called ‘control unit’ that integrates the indicators, wipers and gear selector on a single ‘bar’ mounted to the steering column. It’s another example of modern cars reinventing something we’ve all become accustomed to, but after a day of driving it quickly becomes second nature to adapt to the slightly different controls.

While it may be the same size, Audi has managed to find more room inside, particularly the rear, by redesigning the door pockets and sculpting out the seat backs. It’s still not the roomiest cabin, but the rear seats will be fine for younger families, couples and singles.

Another plus is the 40:20:40 split/fold rear seats for maximum practicality and adaptability, while all three have child seat anchor points (although if you do have three small children, I wouldn’t be recommending an SUV this size). 

As for the boot, because Audi only measures to the top of the seats, it measures 488L in both the SUV and Sportback variants, so you’re not missing out on day-to-day practicality with the sportier-looking roof. However, if you drop the rear seats the cargo capacity expands to 1386L in the SUV but only 1289L in the Sportback.

A key to the popularity of the Q3 is the variety of choices available to customers. By offering a mixture of variants at different price points and with different levels of performance expands the appeal of the Q3 to as many potential buyers as possible. To that end there are no less than 10 variants to choose from, and that’s just for now, with more likely to join in the future.

At this stage the range includes both SUV and Sportback body styles, the choice of a 110kW, 150kW or 195kW engine with front- or all-wheel drive (or quattro, as Audi calls it). While still not confirmed, both a plug-in hybrid and a high-performance RS Q3 are both likely additions sometime in the future.

Starting with the 110kW model, standard equipment includes 18-inch alloy wheels, adaptive LED headlights, ambient interior lighting, keyless entry and ignition, leather-appointed upholstery and a 10-speaker sound system. The 110kW SUV is priced from $61,600 and the Sportback from $64,600.

Moving up to the 150kW quattro variant adds adaptive dampers, which the 195kW models also get, as well as 19-inch alloy wheels, and there’s an optional premium Sonos system for the more powerful models and a panoramic glass sunroof and a head-up display as part of a $4400 option package. Pricing for the 150kW begins at $70,200 for the SUV and $72,700 for the Sportback, while the 195kW is priced from $81,900 (SUV) and $84,400 (Sportback).

There’s also a Launch Edition available which adds between $5400 and $4400 to the price (depending on variant), but includes the S line exterior styling package, black exterior highlights, metallic paint, red brake callipers, a sound actuator and adaptive dampers. As the name implies, these are only available for launch of the new model, so will only be produced for the first two months.

It should also be noted that standard 110kW models won’t arrive until mid-year, once the factory in Europe is done producing the Launch Edition variants.

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.

As mentioned above, there are three powertrains to choose from initially, with talk of a plug-in hybrid and hi-po RS Q3 just that (talk) for now.

The entry-level SUV and Sportback get a new 1.5-litre four-cylinder mild-hybrid, turbocharged petrol engine, which makes 110kW/250Nm and sends all that performance to the road via the front wheels through a seven-speed, dual-clutch automatic transmission.

Next up is the TFSI 150kW quattro, which is a bigger 2.0L turbo-petrol four-cylinder, producing (you guessed it) 150kW and 320Nm. It also has a seven-speed dual clutch but also unsurprisingly has a quattro, aka all-wheel drive.

Finally there’s the TFSI 195kW quattro, which has the same engine but tuned to make 195kW and 400Nm, also with the seven-speed, dual-clutch auto and all-wheel drive.

This is naturally the quickest Q3, at least until the RS Q3 arrives, taking just 5.7 seconds to accelerate 0-100km/h, compared to 9.1 seconds for the 110kW and 7.1 seconds for the 150kW.

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.

While it may only be a mild hybrid, Audi has done its best to make the TFSI 110kW as fuel efficient as possible. To that end, in addition to the hybrid help this new 1.5-litre engine also features cylinder-on-demand.

The result is a claimed combined cycle fuel use figure of 5.7L/100km for the entry-level model.

Naturally the more powerful engines require more petrol. The 150kW models are rated at 7.3L/100km, while the 195kW has a claimed 8.1L/100km.

It’s worth noting that all three engines require a minimum 95 RON ‘premium’ fuel, which will only add to the cost at the pump in these times of high prices.

The 110KW/150kW models are fitted with a 55-litre fuel tank, while there is a bigger 60-litre tank for 195kW. That means theoretical driving ranges of approximately 960km for the 110kW models and just over 740km for the 150kW and 195kW offerings.

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.

While it may not be an RS model or a more dynamic sedan, part of the price premium you pay for an Audi is a more polished driving experience.

With that in mind, what Audi calls ‘Progressive steering’ (which is a variable ratio steering rack) is now standard across the range. This decision was driven by a desire to make the Q3 feel ‘more hatch-like’ to drive, being more responsive to driver inputs.

It certainly felt quite nice to drive at the launch, where we drove across a wide variety of conditions, including long stretches on winding mountain roads. The 110kW Launch Edition was enjoyable to drive in these conditions, even if the other two options offer a sportier driving experience with their extra power and all-wheel drive.

It should be noted again, we only drove Q3s fitted with adaptive dampers as those are included on the Launch Edition, so we can’t tell you how the true entry-level TFSI 110kW model rides and handles.

One minor concern was there were some rattles in one of the three cars we tested, centred around the dashboard and front doors. It’s notable because we have experienced similar potential build-quality issues with Volkswagen and Skoda products recently. This raises some questions about an area Volkswagen Group products have traditionally excelled in.

Having said that, it was only a problem in one of the three cars we drove, so it could be an isolated incident. But it’s something we will have to keep an eye and ear open to in future test drives.

Audi claims this is the safest Q3 ever, with more safety equipment than before to ensure it meets modern customer demands.

There’s a 360-degree camera setup, reversing camera, adaptive cruise control and a host of other active safety features. But perhaps more importantly than just having these systems, they are locally tested and calibrated for local conditions.

This has quickly become an area where the premium brands are separating themselves from the mainstream. In the case of the Q3 we found that the lane keeping assist and adaptive cruise control worked better than your average mainstream model, so the local testing appears to have paid off.

Another safety feature worth mentioning is the new parking assistance system, which now includes ‘reversing assist’. This new technology can remember the last 50m of your trip and reverse backwards without your help. There’s also ‘trained assist’, which can learn up to five specific parking situations, that you can program and save. So, if you have a particular driveway or parking spot you can teach the car once and it can park itself in future.

The Q3 comes equipped with enough safety to score a maximum five-star rating from Euro NCAP and ANCAP. However, in a confusing twist, this is based on testing done to the 2025 protocols, even though the Q3 has only gone on sale in 2026. So future five-star ANCAP models will have been tested to a theoretically higher standard, which is something to consider when comparing models from other 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.

The Q3 is covered by Audi Australia’s standard five-year/unlimited kilometre warranty. This includes five years of roadside assistance too.

There is a standard five-year servicing plan for $3300, which is the same as the outgoing model, with servicing required every 12 months or 15,000km, whichever comes first.

Audi has an expansive, nationwide dealer network befitting its place as an established sales leader in the premium space.
