Mercedes-Benz Eqb250 vs Audi Q3

What's the difference?

The EQB is a likeable yet complicated machine.

On one hand, the high pricing is a real hurdle, even in the base 250, while the 350 4Matic costing the wrong side of $110K driveaway can’t even be had with seven seats. What is the point of it? 

On the other, though, the EQB is roomier than its appearance suggests, way lovelier inside than anticipated, and – especially after allowed to really be driven hard and fast – a whole lot more Mercedes-Benz in the way the 350 4Matic moves, steers, grips, rides and stops.

As a result, we’d skip the capable but bland 250 and try to haggle hard on the price of the altogether too-expensive yet compelling 350 4Matic instead. It’s the EQB to be in.

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.

The EQB does not employ a dedicated EV architecture – sometimes referred to as a ‘skateboard’ platform – like the Tesla Model Y, or for that matter the brilliant Hyundai Ioniq 5, Kia EV6 and Genesis GV60 at around the Benz’s price points.

By this, we mean that it was originally designed as an internal combustion engine (ICE) vehicle. In this case, what lies beneath is the MFA2 platform, first seen in the redesigned A-Class hatch back in 2018, and applied to all transverse-engined Mercedes models since.

The upshot here is that there are some compromises as a result compared to the aforementioned EV-only alternatives, namely concerning packaging as well as weight distribution in some cases.   

Like we said earlier, the EQB’s design is eye-catching and quite handsome. It is clear that the success of the GLB that spawned it is partly attributed to the chunky, almost function-over-form tall-boy utilitarian styling. That ‘W’ shaped window-line kink is an interesting visual feature too.

The changes from GLB to EQB do give the EV definite points of difference, from the front-end’s black flat panel and fibre optic light that connects the (blue-highlight) headlights, to the curved strip LED tail-lights and bumper-sited numberplate mount.

We reckon the 20-inch AMG turbine wheels really do enhance the EQB aesthetically as well, but of course they’re an option on the 250. Though probably not in Gold Rose.

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.

As with the popular GLB that spawned it, there’s more to the EQB than meets the eye.

Photos mask the German electric vehicle’s considerable length and height as well as the substantial space offered inside, giving the Mercedes a handy advantage compared to premium alternatives like the Volvo XC40 Recharge, the Genesis GV60 and BMW’s recently announced (and quite handsome in the flesh) iX1 due early next year.

In fact, the EQB’s lengthy 2829mm wheelbase accommodates the batteries as well as impressive cabin packaging flexibility. Its 4684mm body is actually 26mm longer and 37mm higher than the larger, current-shape (X253) GLC, though width is identical to the EQA, making this a long, tall but quite narrow SUV proportionally speaking.

That expansive feeling is boosted by deep side windows offering reassuring all-round vision, boosted by an excellent driving position. All launch vehicles had the AMG sports seats (optional on the EQB 250, so we can’t speak for the base model), but as tested, they provided hours and hours of comfort and support. Loads of adjustability also help.

The EQB’s dash design is attractive and contemporary, though it can also seem daunting at first, requiring time to learn and understand where all the switchgear and controls are. The ‘Hey, Mercedes’ voice command mostly works well, too, and can provide additional tuition. The multimedia screen can be swiped like a tablet/iPad, or controlled via a fiddly touchpad on one of the steering wheel spokes.

Once mastered, the layout is logical and operation clear… with the exception of the drive selector on the right-hand side, which can be confused for an indicator and so knocked out of ‘gear’ and into Neutral on a regular basis. This has been a two-decade-long criticism of Mercedes models.

As with most MFA2 vehicles, the interior design and quality are a big step forward compared to earlier efforts. Multi-configurable digital instrumentation (including an elegant uncluttered mode), gorgeous turbine-look vents, a row of classy toggle switches for the main buttons and a great steering wheel are highlights to behold. Storage seems endless, reinforcing the practical nature of this cabin.

Speaking of which, stepping into the rear (second row) seats further underlines the EQB’s spaciousness. Entry/egress is easy due to wide-opening doors, taller folk should find ample room for knees, legs and (especially) heads, and the (slightly reclinable) backrest does its job. Comfy if firm cushions also slide forward (by up to 140mm) when required.

That’s to aid third-row access (where applicable). To that end, the second-row seats also tilt to allow people to squeeze past. Note, though that this is really a kids-only area, rated for occupants no taller than 1.65 metres. Surprisingly cosy, both chairs are OK for short trips, but longer ones would be a stretch too far except for the smallest passengers. 

Keep in mind that all outboard middle and rear seats where fitted have ISOFIX latches for child seats.

Luggage space is another EQB bonus, offering 130 litres with all seven seats up, or 495L with the third-row folded. Drop the middle row and there’s 1710L (or 1620L in seven-seater versions). These figures are between 20L to 60L down compared to the GLB.

Note, too, there is no spare wheel fitted. Just a tyre-repair kit.

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.

As with the related EQA, the EQB uses an asynchronous motor and a single-speed reduction gear transmission under the bonnet to drive the front axle. In the 250, it makes 140kW of power and 385Nm of torque.

Moving on to the 350 4Matic, it delivers 215kW and 520Nm, since a second permanently excited synchronous motor is fitted on the rear axle. This slashes the 0-100km/h acceleration time from 8.9 seconds to 6.2s, though both offer a 160km/h top speed.

This is despite a heavier kerb weight (2153kg, up from 2059kg). Power to weight ratio for the 250 is 68kW per tonne, compared to the 350 4Matic’s 99.9kW/tonne. That second motor sure makes a difference!

Both models use a 66.5kWh lithium-ion battery pack fitted between the axles, with a maximum 11kW AC and 100kW DC charging capability.

As with most electrified MFA2 models, front suspension is via MacPherson-style struts while the rear brings a multi-link arrangement. Steering is by electrically assisted rack-and-pinion.

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.

Using WLTP figures, the EQB 250 has a combined consumption rating of 20.4kWh per 100km, down from the EQB 350 4Matic’s 21kWh/100km.

Maximum range is rated at 371km and 360km respectively. Note that due to challenging flood-water and torrential rain weather conditions, on-road real-world figures were not available during the launch drive.

The EQB offers varying levels of energy recuperation to help recharge the battery pack. In ‘D Auto’ it figures out the level of resistance automatically, but drivers can also choose to do this manually via ‘D+’ that provides coasting, ‘D’ that brings mild regeneration off-throttle, and ‘D—’ that activates maximising regen for close to single-pedal driving. These are paddle activated.

Cables for home charging with three-prong outlets are included – an eight metre long one plus a five metre public charging cable.

Mercedes says that using a 100kW DC charger will take an EQB from 10-80 per cent charged in 30 minutes, while an 11kW AC public outlet needs 4.1 hours and at home using a regular 3kW 10-amp socket requires at least 25 hours.

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.

The most remarkable thing about driving the EQB is how similar the 250 and 350 4Matic seem initially, until when push comes to shove.

Around town, both rise up to meet brand expectations. Easy and smooth off the line, acceleration is sufficiently brisk in the 250 and noticeably stronger driving the 350, as you’d expect in a two-motor EV. Progress is spirited, smooth and refined.

We're also grateful that the engineers seem to have cheekily dialled in connected and agile steering, imbuing the EQB with a likeable athletic attitude that’s just right for weaving in and out of tight traffic spots. Which is quite a feat really, given this car’s substantial size and mass.

Perhaps more surprising is how settled the ride is, no doubt aided by the sheer weight of these two-tonne-plus SUVs, as well as the standard-fitment adaptive dampers. Most bumps are quietly and effectively absorbed.

Out on the open road, the 250 remains sufficiently powerful, offering decent throttle response and quite a relaxed cruising gate. However, if you’re expecting Tesla-matching neck-snapping mid-range thrust, look elsewhere. Same applies to the other model. Though undeniably stronger throughout, not even the twin-motor 350 4Matic can be classed as especially quick.

However, while both EQBs display beautifully balanced steering that go exactly where you need them to be, only the 350 4Matic has the muscle to really explore the lofty dynamic capabilities available at higher speeds.

Across water-logged and desolate rural Victoria, the EQB behaved with exceptional athleticism given its role in life, providing outstanding steering precision, matched by brilliantly reassuring control. We’re talking planted confidence, as the 350 4Matic has the ability to really come together and move with the ebb and flow of a fast country road with outstanding aplomb. Despite teeming rain at times, the Mercedes behaved like you’d hope a swift, safe and sound grand tourer would. Who'd have figured?

Back on the highway, there was plenty of road noise intrusion coming up through the tyres, but otherwise, it seems obvious to us that though you pay more, you do get more with the twin-motor AWD version.

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.

Mercedes-Benz offers a five-year/unlimited kilometre warranty. The battery pack warranty is also industry-standard, valid for the usual eight years/160,000km.

Service intervals are every year or 25,000km. The EQB Service Plan starts at $1625 for the first three years, $2225 for four years and $2650 for five years.

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.
