Mercedes-Benz EQ-Class vs BMW X7

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.

When lined up against its direct rivals, the expensive X7 xDrive40d represents reasonable value for money.

It has a unique and bold look and a sumptuous, visually striking and well-appointed interior that has acres of space for family, friends, or for ferrying frequent flyers to the airport. 

That wallop of performance from the big beefy diesel is the cherry on the top. This is how you do a mid-life update. 

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.

There’s quite a bit that’s interesting about the X7’s design. Especially looking at it front on.

BMW certainly took a bold step when it introduced its toothy grille design for the X7 and the 4 Series range. 

But the Bavarian brand has made some even braver design moves recently by introducing a blocky front-end with split headlights on its new-gen 7 Series flagship sedan. That look has now found its way onto the face of the updated X7.

As with the 7 Series, it won’t be to everyone’s taste. But you can’t deny it has a lot of presence. 

The tail-lights have been tweaked and look good, but the sheer size of the X7 - it’s 5.2 metres long and 1.8 metres tall - means there’s no disguising the fact that it is a big, boxy SUV.

Inside the update ushers in significant design changes. The old dash and cowl is gone in favour of the ‘Curved Display’ that connects the instrument cluster and multimedia. 

New slimline air vents, LED backlit ‘X7’ graphics on the passenger side of the dash, and a new gear shift toggle that replaces the old shifter elevate the cabin and give it a much more modern vibe than the old X7 - one that’s in keeping with the excellent iX electric SUV.

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.

Regardless of the price point, a three-row SUV needs to be super practical and capable of family duties. 

And if you want a BMW X5 but need a lot more space, this is the next logical step.

Let’s start in the front row. As mentioned, the new X7 gains the screen and tech set-up from other new BMW models like the iX and updated 3 Series. The Curved Display combines a 12.3-inch digital instrument cluster with digital speedo and a 14.9-inch multimedia screen.

You can customise the cluster layout and move things around on the multimedia screen, too. The latter is a touchscreen but you can also find what you need via the 'iDrive' controller in the console.

I have had some experience with this system in the iX and while it’s not without its flaws, it is a top notch system. There’s a lot to wrap your head around, but the use of app icons helps. And you can swipe through to your chosen screen.

It took far too long to work out how to find the trip computer, something that should be much easier to access, as well as a couple of other functions. And the climate controls are housed in the digital screen. I would always prefer a separate space with buttons for air-con.  

But the graphics and displays - including the excellent head-up display - are excellent. 

Other tech you get with the X7 includes the BMW’s 'Digital Key', which is an app that allows iPhone users to lock and unlock their car remotely, and BMW ID driver profile.

If you buy this car, just allow yourself some time to familiarise yourself with all that tech.

Elsewhere up front there’s a lovely new three-spoke steering wheel, and cute touches like the metal air vent toggles, black and metal touches and the choice of inserts.

The front seats are luxurious and comfortable and offer loads of side and thigh support. They have memory functions, too. There’s no shortage of headroom up front, either.

Storage-wise, the door will fit the largest of bottles, as well as other items thanks to generous door bins, while the central lidded box is also sizeable. 

What about that second row?

The X7 xDrive40d usually comes standard with seven seats, but our test car was fitted with the $1500 captain’s chair option which drops seating capacity down to six people.

If you need the extra seating this is not the option for you, but it is great for families with bigger kids, and it would make for an excellent airport transfer car. 

The seats are unbelievably comfortable and can be adjusted to suit your preference. They also have ISOFIX points and armrests. 

Rear seat occupants have access to their own climate controls, air vents, USB ports, cupholders and ample door storage.

There is a massive amount of occupant space as well - stretch those legs out and enjoy it!

One of the X7’s selling points is that it is a genuine three-row SUV. That third row is not just for occasional use for very small children, like so many seven-seat SUVs. That row can be used every day. 

Even with my six foot stature, I could easily climb in and out of the third row. That’s made even easier thanks to the mechanical seat functions.

Just hit the lever at the top of the second row seat and the motor moves the seat forward and up to ensure there’s a big enough aperture to get in and out of the rear seats. 

You can also raise and lower the third row electronically via buttons on the boot wall - and they stow flush into the boot floor. Neat!

Once in the third row, there’s air vents, USB ports, bottle holders and storage and quite comfortable seats with more than enough leg and head room.

There’s even a third row section of the sunroof, operated from the second row. Lots of clever touches that people who use the third row will appreciate.

The boot has a few cool features, too, including a split tailgate.

You can even sit on the lower section - it can handle a load of up to 250kg - a perfect place to sit and watch the polo.

You can lower the suspension to aid loading larger items, and the X7 comes with a space-saver spare wheel.

Capacity is 300 litres with all seats in place, and I easily fit a pair of smaller suitcases in with that configuration. It increases to 2120L with the two rear rows folded. 

We are way out of Kluger and Sorento territory with the BMW X7. This is a bus for cashed-up families. 

The upper-large SUV was introduced in mid-2019, but as part of the mid-life update, BMW has changed up the model grades. There are still two, but the xDrive30d and M50i have been replaced by the diesel-powered xDrive40d M Sport, and the performance-focused V8 petrol-powered M60i.

For the purpose of this review, we drove the 40d M Sport, which gets a power boost over the outgoing 30d - more on that in a bit.

As a result of the significant update, BMW has increased pricing on both grades. For the xDrive40d, it now starts at $174,900, before on-road costs, which represents an increase of more than $30,000 over the old 30d.

If you’re after a bigger dollop of performance, the M60i will cost you $205,900.

While the xDrive40d pricing seems steep, it undercuts a couple of other big luxury diesel SUVs including the Mercedes-Benz GLS400d ($179,500 BOC) and the Toyota LandCruiser-based Lexus LX F Sport ($176,091 BOC).

The most affordable diesel-powered version of the new-generation Range Rover starts from $226,806, so in that regard, the X7 40d is the best value in its class!

As well as the updated powertrain and in-car tech, the X7 xDrive 40d now comes with a hefty standard features list including metallic paint, 22-inch wheels, the M Sport pack, five-zone climate control, Harman Kardon 16-speaker sound system, a drive recorder, comfort seats, ‘Comfort Access’, roof rails, electric sunblinds, panoramic glass sunroof, digital radio, a head-up display, ambient lighting, wireless Apple CarPlay and Android Auto, and leather interior.

Our test car was fitted with a number of options that pushed the price to just under $185,000. The extras included huge 23-inch alloy wheels ($3500), BMW Individual 'Dravit Grey' body paint ($2400), a trailer tow hitch ($2500) and second row captain’s chairs ($1500).

Note that if you opt for that tow hitch, you’ll lose the ability to open the hands-free tailgate with a kick motion.

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.

The X7 xDrive40d is powered by a 3.0-litre, in-line six-cylinder turbo-diesel engine, that gets a boost in power - it pumps out 259kW of power and 720Nm of torque - 64kW/100Nm more than the 30d.

It now also comes with 48-volt mild hybrid tech, which uses an electric motor integrated in the eight-speed automatic transmission.

It drives all four wheels via BMW’s 'xDrive' all-wheel drive system and it is fitted with air suspension for a cushy ride. Towing capacity is rated at 3.5 tonnes braked or 750kg unbraked.

If you are keen on off-roading in the X7, it has a 221mm ground clearance, and a fording depth of 500mm, but maybe best to keep it on the tarmac.

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.

According to BMW, the official combined cycle fuel figure for the X7 40d is 8.0 litres per 100 kilometres.

Our fuel figure after nearly a week of mixed city, freeway and country driving was 9.0L/100km, which isn’t too far off the mark.

It has an 80 litre fuel tank and an approximate driving range of 1000km.

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. 

With a big plush SUV like this, you’d expect a comfortable ride. And for the most part, the X7 delivers that, while offering more than a bit of grunt, as well.

The X7’s height ensures a high driving position, and there’s plenty of glass for decent visibility. 

Propelling a 2.5-tonne SUV could be a struggle for a lesser engine, but the meaty diesel offers ample torque and the mild hybrid set-up helps to reduce initial turbo lag significantly - that means it is responsive from a standing start.

I wouldn't have thought a vehicle of this size and shape was capable of a 5.9-second 0-100km/h time, but here we are.

As a result of all that torque and power, overtaking is a breeze - providing there is enough room on the other side of the road for both cars to fit.

That size and heft have an impact on cornering and dynamics. You simply can’t carve through tight corners in this car, but with that said, it’s more entertaining than you’d think. 

Steering feel is weighted on the heavier side and it’s as sharp as it needs to be in a car like this. It would be weird if the steering was too pointy. 

Ride quality is top notch - as it should be - and while the massive optional 23-inch wheels and low profile tyres mean you’ll notice potholes and the like, it largely soaks up imperfections with ease.

That level of refinement extends to the hushed ride, too. The cabin is a quiet and serene place to spend time - but not quite to the same degree as a 7 Series. 

Parking in tight spots is a challenge, and manoeuvring in narrow streets could take a while, too. But you could tell that just by looking at the X7.

The X7 has size on its side when it comes to occupant protection, but it also comes with a decent level of safety gear as standard.

Features include auto emergency braking (AEB) with pedestrian and cyclist detection, a safe exit assist function to avoid 'dooring', and an advanced lane keeping aid, ‘Parking Assistant Professional’, ‘Trailer Assistant’, and hill descent control.

The X7 is yet to be crash tested by the local safety authority, ANCAP, or by Euro NCAP.

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.

After copping a bit of flack from motoring media and buyers, BMW finally increased its warranty terms last year from three years to an industry standard five-year, unlimited kilometre warranty on its vehicles, including the X7.

Rather than a set servicing schedule, BMW offers condition-based servicing which is when the vehicle’s computer alerts the owner that it requires a service. 

BMW doesn’t offer capped-price servicing, but does have a pre-paid 'Service Inclusive Package' with terms ranging from three years/40,000km to five years/80,000km and beyond. 

A five-year basic package for the X7 costs $2800, which is not too bad considering the positioning of this model.
