Mercedes-Benz EQB vs Tesla Model 3

What's the difference?

I really liked the combustion version of this car, the GLB, for its funky style and flexibility and I was pleased to find how easily Mercedes has made the conversion to a fully-electric layout for the EQB.

Despite a tall price, the EQB 350 is a compelling option for those seeking something a bit more luxurious than the Tesla Model Y, something a bit larger than the Volvo XC40 Recharge, and something a bit smaller than the Audi e-tron or the EQC.

The main trade-off for this 350 variant is the loss of the seven-seat layout in favour of more performance. Instead it offers a huge boot, has a sufficient range for city-based buyers, and offers surprising levels of fun, too. 

Just make sure you’ve considered its rivals which may potentially offer more range or features for the same money.

The Model 3 Performance is one of those cars that’s undeniably impressive in almost every way, and hugely fast in absolutely every way, and yet can somehow still leave you feeling slightly cold. Or at least damp with fear sweat.

It’s not my kind of sports car, but if you love speed, and EVs, and Tesla, you’re gong to think it’s the Queen Bee’s knees.

Publishers: Please place the following in BOLD after the verdict:

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

The EQB has a very predictable design in that it doesn't stray from the combustion car’s formula. At all.

The only evidence from the outside this is the electric version is the blanked out grille, and closer observers might notice the rear light bar which cuts across the boot lid is different from the split tail-light design which appears on the combustion car.

Still, to my eyes, the GLB is a cool design with its upright boxy look bucking the curvaceous trend of most EVs, and, indeed, the rest of the Mercedes line-up. 

Its rebellious streak makes it one of the most appealing SUVs in Mercedes’ current range, and it comes with a bit of toughness which is missing from the EQA. 

If nothing else, it’s a completely different look from Tesla’s amorphous Model Y, and this may be enough to appeal to some.

Inside is identical to other Mercedes models which sit on the MFA2 small car platform, immediately setting itself apart with the big high-resolution screens, glitzy ambient lighting, as well as an abundance of chrome and gloss black.

It’s designed to impress from the first time you hop in, and there’s no doubt it does, but it may be a bit over-the-top for some, particularly fans of the more conservative Mercedes designs of eras past.

The chrome in particular becomes a bit of a problem, as it has an annoying habit of catching the reflection of the sun and sending it directly into the driver’s eyes.

It all feels as plush as a circa-$100,000 luxury car should though, with the ‘Artico’ seat trim being one of the better synthetic options on the market, and soft-touch surfaces throughout the cabin selling the Mercedes promise. 

The GLB toughness is even reflected in the chiselled out finishes in the door, dash, and centre console, helping to set it apart from the tamer EQA.

The software is also fast, high resolution, and well presented, which bodes well given the amount of screen real-estate, and the amount of customization is impressive, too.

Again, there are many who will prefer its look and feel to the Apple-store chic of the Tesla Model Y, or the pared back Scandinavian approach of the XC40 Recharge, but also those who won’t. Like many new Mercedes products, it continues to polarise buyers.

Tesla’s design folks waxed long and loud about how they’d finally been able to visually lift and separate this Performance Model 3 from the basic one and they point to the new front and rear fascias, more aggressive styling, aerodynamic flicks, integrated cooling ducts, rear diffuser and carbon-fibre spoiler, which are there not only to look good, but to to “optimise lift balance and high-speed stability”.

Now, I’ll grant you it’s better than a normal Model 3, and that we were regularly approached by excited Tesla fans asking “is this the NEW PERFORMANCE OH MY GOD I WANT ONE NOW?!?"

But honestly, I still think it’s a bit subtle, and that includes the strange little 'Performance' sticker/badge on the rear, which does look a lot like the Ludicrous symbol that Elon loves, from the awful movie Spaceballs, but Tesla staff insist it’s not, nor is it Plaid. 

Clearly, the design tweaks are there for a reason, and train spotters will note the differences immediately, but it’s still just not the most exciting car to look at, nor is it anywhere near as exciting to behold as it is to drive.

This should be the GLB’s calling card. It’s a car with an ideal footprint, not as wide or as long as most mid-size SUVs, whilst also offering a larger cabin and boot.

The big drawback for this variant in particular is the lack of a seven-seat option, as the all-wheel drive requires the under-floor space which is required to give rear occupants legroom. 

It’s a shame, too, because I found the two rear seats in this car’s GLB combustion equivalent to be surprisingly accommodating for even adults.

As a result of these missing seats, though, the full volume can be exploited in the boot, which comes in at a whopping 495 litres.

It’s rivalled by the Model Y, which also has a cavernous boot, although it has a much larger storage area than the Volvo XC40. 

As an added bonus, there is a decent under-floor storage area which has enough space for all your charging cables, although there is no so-called ‘frunk’ with what is normally the engine bay taken up by cooling and auxiliary hardware. 

At first glance there’s so much going on under there, you’d be forgiven for thinking the EQB has an actual engine!

The cabin is also enormous as well as configurable. The EQB has massive rear doors (as it’s designed to be a seven-seater) to make it easy to get in and out of, and once you’re settled in, the amount of space for me (at 182cm) behind my own driving position is very impressive, with ample leg, arm, and headroom.

Rear passengers score the same nice synthetic leather seat and door trim as the front passengers, a bottle holder in each door, as well as two in a flip-out caddy on the drop-down armrest, two nets on the backs of the front seats, dual adjustable air vents, and power outlets on the back of the console. There is also a separate section of the split sunroof to benefit those in the back seat.

Up front the cabin is equally flexible, although it immediately seems odd that the front seats are manually adjustable. Almost unforgivable in a $100,000 car. 

At least the trim is comfortable, and again, the space is configurable for people of all shapes and sizes. 

Storage options include large bins in each door, a split-opening armrest console with USB-C outlets inside, a slide-open area underneath the climate unit, which houses a wireless phone charger and additional power outlets, as well as the usual glove box arrangement. 

Soft trims continue into the doors, although one small annoyance is the excess of chrome trim which has the unfortunate habit of reflecting harsh Australian sun into your eyes if it hits at the wrong angle.

The software is nice and quick, but can be cumbersome and over-complicated to operate at times, particularly when using the centre touchpad, or adjusting the dash with the small touch elements on the wheel. 

It is also notable the Apple CarPlay as-tested only took up a centre portion of the screen, and is not set-up for widescreen mode to take full advantage of the hardware.

Minor complaints aside, though, the EQB follows its combustion GLB twin in having by far one of the most flexible and configurable cabins in its class.

Inside, the big news is the new seats. Tesla was happy to admit the pews fitted to the previous Performance just weren’t up to the job of holding humans in place when applying so much G force. 

The new 'Sport Seats' feature enhanced side cushioning and side bolsters for better lateral support during dynamic driving. And they can also be heated and ventilated. 

Elsewhere, there’s some carbon-fibre trim on top of the dash, with a Tesla-first weave pattern to further help the Performance stand out within the Model 3 line-up.

Other than that, it’s pretty standard Tesla sedan, which will be familiar if you’ve ever caught an Uber in Los Angeles. Spartan, minimalist, slightly cheap-feeling.

As for the practicality of the tech, I'm still against the giant 15-inch tablet-style touchscreen, for everything, the replacement of an indicator stalk with buttons and not having a speedo right in front of your eyes, where you need it.

Tesla says the price for the Model 3 Performance will be "starting at" $80,900, plus on-road costs. There's no word on whether there will be different spec levels and the company does not like answering questions or providing information.

What we also know about Tesla is that the price quoted could move down, or up, at any time, quite randomly, so if phrases like "residual value" or "depreciation" are of interest to you, it can be a challenging brand.

That side swipe aside, this sounds like astonishingly good value for this much performance from your Model 3 Performance. A Hyundai Ioniq 5 N would give it run for fun and involvement, if not brand fans, but it's $111,000, while a Porsche Taycan kicks off at $164,000 (it is a lot more car for the money, but it might struggle to keep up with this Tesla, at least in base model form).

In terms of equipment, it's pretty much standard Model 3 fare, other than the fast bits and a spot of carbon here and there.

You get 'Autopilot' included, of course, but you can't use all of its 'Full Self Driving functionality' on Australian roads. Not yet, anyway.

While the EQB 350 loses its valuable third-row seats, it gains a much more impressive drivetrain than the lesser EQB 250 variant. 

While that car has a so-so front-motor set-up producing 140kW/385Nm, the top-spec 350 sports a much more capable 215kW/520Nm dual-motor system.

This allows a 0-100km/h sprint time of 6.2 seconds, and while it’s not as fast as the entry-level Tesla Model 3, it’s still impressive for a 2153kg SUV.

The all-wheel drive capability also adds a level of confidence which can’t be matched by a front-drive, more on this in the driving section of this review.

If you’ve ever driven the previous Model 3 Performance you’ll know that it could well have come with Space X badging (arguably Elon’s more impressive engineering achievement), because it really did thrust rather than accelerate.

But this time the engineers wanted to go all out. Customers appreciated the incremental performance they got from the last Model 3 Performance version, but they told Tesla they wanted more.

With many enthusiasts among Tesla's engineering and development team, they looked to unlock the performance potential of the platform.

So, that meant a whole lot more madness and torque thump. It comes from a new Performance 4DU, an all-new drive unit - featuring an entirely new rear motor that uses bar-winding technology - unlocking 22 per cent more continuous power, 32 per cent more peak power and 16 per cent higher peak torque delivery. 

Overall figures are 380kW and 740Nm, but looking at them written down, they seem big, yet not as big as they feel in this car, as it’s shoving you from a standing start to 100km/h in three seconds flat. 

It feels faster. Sick-making fast, even.

Regardless of which version of the EQB is chosen, the SUV has a 66.5kWh lithium-ion battery pack, and in the case of our all-wheel drive 350, this grants it a 360km WLTP-rated driving range between charges.

My car was reporting around 350km of range at or near a full charge, while my week of testing produced a dash-reported consumption figure of just 18.2kWh/100km.

This is surprising for two reasons. Firstly, I subjected the EQB 350 to a significant amount of freeway testing during my time with it, which usually produces worse consumption numbers for EVs, but it actually bested its official 21.0kWh/100km official figure by a decent margin.

Secondly, I’m puzzled to find this car outperformed the smaller and lighter EQA 250 I had on test in 2021 in terms of overall consumption, and by a significant margin. Very odd.

When it comes to charging up, the EQB can be charged at a rate of 100kW on a fast DC charger, for a 10-80 per cent charge time in a claimed 30 minutes. 

On the slower but cheaper-to-install AC standard, the EQB has an 11kW inverter, allowing a convenient ‘slow’ charge time of 4.1 hours. Expect between 25 and 30 hours on a standard wall socket.

Despite being heavier and gruntier, Tesla claims the new Performance Model 3 manages to be more efficient than the one it replaces, albeit delivering just a two per cent reduction in energy consumption. Claimed energy usage is 16.7 kWh/100km.

Tesla claims a total range of 528km on the WLTP, which is obviously going to drop if you drive it the way its makers clearly intended.

Using a Tesla Supercharger, you can add 228km in 15 minutes and... that's all Tesla will tell us. There are no official figures available for how long a full charge takes, on either a Tesla charge or a home wallbox of your own.

This is where the 350 version of the EQB shines. This car is a beast to drive with plenty of power available at your right foot, and incredible amounts of traction to match from its torque-vectored all-wheel drive system. 

This lets it be rapid, but not scary, and despite its square and upright body, might surprise you when it comes to carving a few corners.

Like many EVs, the EQB’s weight feels low and centred, but it appears the suspension has been adjusted to remove any bouncy quality, which might come with the additional weight added over the combustion variants, with nearly 500kg of lithium batteries under the floor.

In fact, the ride is also one of the things which impressed me most about the EQB. It even has huge 20-inch AMG wheels, yet it dealt with bumps of all shapes and sizes in an impressive manner, keeping the body under control, and communicating remarkably little in terms of vibration or unpleasantness into the cabin.

The steering offes a nice balance of feel and electrical assistance, a trait which combines with the EQB’s convenient size to make for an easy SUV to park and manoeuvre.

When it comes to the EQB’s traits as an electric car, there are several modes available to alter the experience. 

Using the paddle shifters, there are several regenerative braking settings to choose from. While none of them are a ‘single pedal’ mode, the D- mode is pretty strong, and clearly contributed to the EQB’s surprisingly good energy consumption in my time with the car.

Activating D+ mode, which can be combined with a sporty driving setting, tones down the regenerative setting almost completely and feels as though it unleashes more potential from the potent electric motors. 

While the sportier settings made the 2WD EQA I tested last year feel a little twitchy and prone to wheelspin, the all-wheel drive system keeps this well under control in the larger EQB for impressive acceleration characteristics.

The breadth of this SUV’s ability is perhaps its most impressive attribute. It can feel comfortable and tame around town, with alarming speed and tenacity when attacking the open road should you so desire. 

Sure, it’s not as whiplash-inducing as some of its rivals, particularly the Volvo XC40 Recharge or Tesla Model Y, but for a luxury SUV like this it’s more than what you could ask for. 

Very occasionally, one drives a car that makes the human body feel inadequate to the task. I would have worried that I’m getting old, that my body is simply too flubby and my brain too broken, to cope with the kind of wild acceleration and brutal g-forces the Model 3 Performance delivers.

But, fortunately, I had a videographer in the passenger seat, a much younger man who loves fast cars, and he kept threatening to vomit when I drove it hard, too. 

I’ve driven quite a few cars that you can use make your passenger sick, or hurt their necks - one obvious competitor in the shape of a Porsche Taycan Turbo S comes to mind - but it’s very rare that a vehicle is so intense it can make you, the driver, feel bilious.

Yes, you do bring this on yourself, by choosing to push this Performance anywhere near its limits through particularly sharp and intestine-shaped roads like the canyons outside Malibu Tesla chose to launch it on. 

On longer, sweeping bends it was far more of a joy, and less physically punishing, but in the tight stuff it often felt like corners were being thrown at you, as if you were driving behind the Millennium Falcon and being pulled along in its wake.

The brakes, special new sporting ones with track-ready pads, were up to the task, even though it often felt like they couldn’t possibly pull you up from the speeds you were doing.

And yes, it was entirely my fault that the very first time I even gently prodded the throttle and it launched me ahead past a California Highway Patrol officer, that was my fault too. Three minutes into the drive, holding an American fine, I had already deduced that perhaps this car was too fast for my own good.

But lots of EVs are fast in a straight line, you’re really comparing the length and depth of your “oooophhh” sounds at this point, but where this one succeeds is by being a lot better in the handling and ride and cornering departments than most.

Tesla’s stated goal with this car was to move beyond straight-line speed, to become more than a one-trick pony, and to do that it’s given the Performance a stiffer structure overall and updated the springs and stabiliser bars. 

Aerodynamic changes have reduced drag by five per cent, delivered a 36 per cent lift reduction, and a 55 per cent improvement in front-to-rear lift balance.

Tesla’s own, in-house version of adaptive dampers, not an option but included in every Performance, work with the car’s 'Vehicle Dynamics Controller' through its various modes - 'Insane' and 'Track' being the most… ludicrous - to immediately respond to driver inputs. 

The Performance rides well on LA’s awful concrete freeways but feels absolutely nailed down when you attack even a bumpy driver’s road.

This version also has a lot more power going to the rear wheels, to help it feel more sports-car playful and to fire out of bends the way an enthusiast’s car should. And make no mistake, I met them, the people behind this car are serious driving enthusiasts (although they demur, slightly, on whether their boss is one).

Track mode will allow some serious adjustability, drifting ability and fun, so the kind of people who want to hurl around a racing circuit in silence will love it.

Perhaps the only let downs are that it still feels a bit austere inside, just not very special, and that the steering is just a bit digital, soft and uninvolving, compared to the cars they clearly benchmarked against - BMWs and Porsches. 

Tesla provided no information about safety for the Performance Model but it is assumed it will be unchanged from a standard Model 3.

Aside from Autopilot that means auto emergency braking, lane keep aids, and instead of blind-spot monitoring, it gets the surround radar view and blind-spot cameras when you indicate.

The latest Model 3 has an additional centre airbag for a total of seven, as well as additional bolstering where the doors meet the body in response to requirements in its American home market.

It should be able to carry its maximum five-star ANCAP safety rating, which the original version achieved in 2019.

Mercedes offers a five year and unlimited kilometre warranty, with five years of roadside assist. The high-voltage battery components are also covered by a separate and industry-standard eight-year and 160,000km warranty.

Service intervals are once every 12 months or 25,000km and the service plan costs an average of $440 a year for the life of the warranty which is expensive for an EV, especially considering Polestar offers free servicing for the first five years, and Volvo’s electric offerings are around half the cost over the same period.

Again, we've been asked to assume the Performance will come with Tesla's standard four-year/80,000km warranty and roadside assistance. And that the battery and drive unit will fall under an eight-year/192,000km warranty, whichever comes first.

Tesla says it monitors its cars to ascertain when they need servicing, and so it is based on a case-by-case situation. Every 12 months/20,000km is recommended for a general check-up, and includes tyre rotation.

Wiper blades, brake fluid and cabin air filters need replacement every two years while the air-con service is every six years.

Of course, there are no oil changes, filters or spark plugs to replace, and even brake pad wear is less than on an ICE vehicle because of the regenerative braking system. Although it will likely be higher in the Performance variant.
