What's the difference?
BMW has recently launched its fourth-generation (G45) X3 range, which comprises three petrol variants including the entry-level 20 xDrive, mid-grade 30e xDrive PHEV and top-shelf M50 xDrive.
The new trio brings revised powertrains, new exterior and interior styling, increased standard equipment, enhanced technology and an emphasis on the use of sustainable materials.
We recently trialled the five-seater flagship to see if it has the right mix of performance and practicality to maintain the X3’s enduring appeal for Aussie families.
Iconic/gangster G-Class Geländewagen aside, is there a cooler-looking Mercedes-Benz SUV than the GLB and so – by association – its electrically-powered EQB twin?
And while we're asking questions, does the electric connection make the EV version even more so?
Let’s take a deeper dive into the new EQB – a striking SUV that Mercedes reckons will be its bestselling EV for the foreseeable future. Because there's much more to this Benz than meets the eye.
This is a highly competent all-rounder, given that it has the comfort and practicality for urban family duties yet with its revered M breeding can produce a level of performance which, in competent hands, could hold its own at a track day where its capabilities could be safely explored.
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.
The fourth-gen X3, which has a lighter but stiffer body, shares the same wheelbase as its third-gen predecessor but at 4755mm end-to-end it's 34mm longer and it's 29mm wider.
It’s also 25mm lower, which combined with front and rear track-width increases and adaptive suspension damping to sharpen the handling underlines its sportiness and driver appeal, despite a substantial 2055kg kerb weight.
The new exterior design is characterised by short overhangs, flush door handles, a larger ‘split kidney’ grille, new LED taillights and L-shaped light elements for the LED headlights.
The new interior design is a classy mix of soft-touch materials and high-gloss hard surfaces in tastefully contrasting tones. The seats are upholstered in a new synthetic leather called 'Veganza' ('Espresso Brown' in our example) which according to BMW requires 85 per cent fewer CO2 emissions to produce than genuine leather (which is still available as an extra-cost option).
Combined with subtle use of ‘Magnolia’ fine-wood trim inserts, satin chrome, piano black, blue/red M highlights and slender ambient light-strips, it’s a cabin that exudes opulence.
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.
This would make a great family weekend escape machine, for which BMW quotes a 645kg payload rating. It’s also rated to tow up to 2500kg of braked trailer, which could pose a challenge given the relatively low 100kg tow-ball download limit (TBD is typically around 10 per cent of trailer weight).
BMW also does not publish a GCM figure (how much it can legally carry and tow at the same time) so we can’t confirm if it can carry its maximum payload while towing its maximum trailer weight.
Even so, the M50 has a useful-sized luggage area which offers up to 570 litres (or 0.57 cubic metres) of load volume with the rear seat upright.
This expands to 1700 litres (or 1.7 cubic metres) with the rear seat folded flat, which can be handy for a multitude of tasks like transporting a mountain bike or hauling home flat-pack furniture.
There’s comfortable space for the driver and front passenger, along with useful storage including large bottle-holders and bins in each front door.
The centre console has two small-bottle/cupholders plus wireless phone-charging and a pair of USB ports. There's also a glove box plus another box at the rear of the console with a padded lid that doubles as an elbow rest.
The rear bench seat is surprisingly spacious, given that I’m 186cm tall and when seated behind the driver’s seat in my position I still have about 40mm of knee clearance, which is optimised by the concave shape of the front seat backrests.
The spacious and airy feel is enhanced by the ‘panorama’ glass roof which spans the full length of the seating area and allows generous headroom even for tall people.
However, shoulder room is tight for three adults and the centre passenger’s feet must contend with the transmission tunnel, so even though it would be fine for three kids we’d suggest a limit of two adults for longer trips.
Rear passengers get privacy glass and pull-up roller sunshades, large-bottle holders and bins in each door plus net-type pockets and anchorage points for media devices on each front seat backrest. There are also two small-bottle/cupholders in the fold-down centre armrest.
The rear of the centre console has two USB ports, adjustable air-vents plus controls for zone temperature, airflow preferences and seat-heating.
The bench seat features a 40/20/40 split, which allows the centre backrest to fold forward independent of the two outer backrests to allow long loads like snow skis, home hardware etc to be carried if securely fastened.
A power tailgate provides access to the luggage area, which is equipped with a handy 12-volt accessory socket plus load-anchorage points front and rear, extra storage nooks for small items on either side and a retractable roller-type load cover. Overall, this vehicle offers good practicality for family duties.
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.
Our X3 M50 xDrive test vehicle, finished in new 'Dune Grey Metallic', comes standard with a 3.0-litre turbocharged inline six-cylinder petrol engine incorporating 48-volt mild-hybrid technology, plus an eight-speed automatic and permanent all-wheel drive for a list price of $128,900.
You’d expect a high performance prestige vehicle costing six figures would be packed with desirable standard features and the M50 xDrive delivers, starting with big 21-inch 'M' lightweight alloy wheels shod with wide 285/35R21 tyres.
However, there’s no room for a spare (not even a space-saver) so you get a tyre repair kit instead.
The standard equipment list also includes adaptive LED headlights (with matrix high-beam and blue design detailing), a power tailgate, an ‘Iconic Glow’ illuminated kidney grille with M-specific elements, quad exhaust outlets, a panorama full-length (fixed) glass roof, a choice of six premium metallic paint colours and more. The 'M Sport Pro' visual enhancement package is also included.
Step inside and the driver is treated to a head-up display and an elegantly curved digital dash display, which spans about two-thirds of the cabin's width. It seamlessly incorporates a 12.3-inch driver’s instrument display (made from recycled polyester) and 14.9-inch multimedia display controlled by BMW’s latest 'iDrive System 9' software.
Premium audio is provided by a 15-speaker 750-watt Harman Kardon surround sound system, which includes digital radio and wireless Apple/Android connectivity. There’s also wireless phone charging.
The driver gets a thick leather-rimmed and heated 'M Sport' flat-bottom steering wheel and the driver and front passenger are also treated to sumptuous bucket seats with multiple power adjustments and heating/cooling.
Up to three passengers can share the rear bench seat and indulge in the luxury of three-zone automatic climate control, heating for the outer seating positions, privacy glass, roll-up sunshades, two USB-C ports and lots more.
Tricky one, this.
Kicking off from $87,800 (all prices are before on-road costs), the EQB 250 front-wheel drive is nearly $24,000 more expensive than the 1.3-litre turbo petrol-powered GLB 200 FWD equivalent.
From a numerical power-output point of view, however, the GLB 250 4Matic (which adds a 2.0-litre turbo petrol engine and all-wheel drive) only costs $10,265 less, which evens things out a bit more.
But wait. To match the GLB 250 4Matic spec, you’ll need to tick the $2900 third-row seats option box in the EQB 250, while AWD is unavailable, even as an option.
An electrified future comes neither cheap nor without compromise, no matter how much you frame it.
At least that $87,800 (which sits neatly between the EQA and EQC EV SUVs) does bring some interesting technology, starting with a 140kW electric motor mounted up front, as well as a sizeable 66.5kWh battery with a rated range of up to 371km (WLTP).
For more power and AWD, you’ll need the EQB 350 4Matic priced from $106,700, adding a second, rear-mounted electric motor for all-wheel-drive traction, upping the power output ante to 215kW, though range drops slightly to 360km.
But the latter is not available in seven-seat form as in some overseas markets, due to weight-related packaging safeguards. Sorry. It’s 250 or nothing if you need a third row.
On the safety front, you’ll find Mercedes’ Driver Assistance Package that includes autonomous emergency braking, blind-spot monitoring, lane-keep assist and adaptive cruise control, as well as evasive steering and a ‘Parking Package’ featuring front and rear parking sensors and a surround-view camera.
Both models also boast LED headlights with high-beam assist, keyless entry/go, a Nappa-sheathed leather wheel, two 10.25-inch digital screens (for instrumentation and multimedia touchscreen), artificial leather upholstery, electric and heated front seats, dual-zone climate control, ambient lighting, ‘Hey, Mercedes’ voice control, a 10-speaker audio system, digital radio, wired Apple CarPlay/Android Auto, a wireless smartphone charger, a sensor-activated powered tailgate and alloy wheels (19-inch on 250 and 20-inch on 350 4Matic).
Keep in mind too that adaptive dampers are standard across the range.
Along with that second motor and AWD, the EQB 350 4Matic also adds a panoramic sunroof, sports seats, microfibre trim inserts, a flat-bottom steering wheel, illuminated door sills, a top-stitched dash and an AMG body kit.
For its first year on sale, the Edition 1 ($9100 extra on 250 and $3900 more on 350 4Matic) ushers in the AMG body kit on 250, Gold Rose 20-inch alloys, a Night Package with darkened highlights, illuminated sills, unique colour leather trim and vents, a different key, AMG mats and backlit interior elements.
Buyers of the EQB 250 can also choose other packs including an AMG Line Sports Package for $4300 and a $3000 Vision Package brandishing a Burmester audio upgrade and sunroof, while both models can be had with a $2500 MBUX Innovation pack offering a head-up display, MBUX Interior Assist that ‘senses’ hand gestures for the touchscreen and other functions, as well as MBUX Augmented reality for the standard navigation system.
At these prices, we'd argue they ought to be standard on every EQB...
There’s also a Mercedes-endorsed Wallbox option from $1710 if your home/work residence qualifies, bringing a Type 2 AC Charger, 22kW, single-phase and three-phase charging. A free Chargefox subscription is also expected to be announced shortly.
Direct, all-electric EQB rivals are very thin on the ground. Those optional third-row seats on the 250 are unique in the sub-$100K EV SUV field, with only the larger and more-expensive Tesla Model X offering the same. For now.
The EQB 350 4Matic, meanwhile, might offer a surprising amount of space and practicality, but at its six-figure starting price, it seems expensive for what you get.
According to BMW, the M50 xDrive features the most powerful inline six-cylinder petrol engine fitted to an M Performance model.
This 3.0-litre unit clearly benefits from BMW’s twin-scroll turbocharging technology, which combined with variable valve timing and an extra 13kW/200Nm from the 48V mild-hybrid technology produces a stomping 293kW of power at 5500rpm and 580Nm of torque at 1900rpm.
It also has a ‘boost’ function, which provides an extra burst of power for short periods when maximum acceleration is required when overtaking etc.
It’s activated by the left paddle-shifter on the steering wheel and automatically optimises transmission/chassis settings to suit. There’s also a drive mode selector, with ‘Sport’ offering the most responsive and engaging experience.
The eight-speed torque converter automatic is a refined and efficient transmission well suited to this full-time all-wheel drive application. Rapid-fire manual shifting is also available using the steering wheel paddles.
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.
BMW claims an official average combined consumption of 8.2L/100km but the dash display was showing 9.9 at the completion of our 210km test, which included a mix of suburban, city and highway travel.
Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly higher again at 10.5L/100km, which given our test vehicle’s two-tonne-plus weight and performance capabilities is still reasonable economy.
So, based on our figures, you could expect a realistic driving range of around 600km from its 65-litre tank, which prefers premium 98 RON petrol.
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.
First, the fun stuff. It certainly feels like ‘the ultimate driving machine’ when you slide behind the chunky leather-rimmed flat-bottom steering wheel and hold it in your hands.
The driver’s seat offers not only powered adjustment of backrest and base-cushion rake, but also four-way lumbar support and side-bolsters that can tighten their embrace of your upper torso to contend with high cornering loads.
There’s also manual extension of the base-cushion length for greater thigh support and a big left footrest to brace against, so you could not ask for a more accommodating and purposeful driving position.
The steering is perfectly weighted and the quartet of enormous disc brakes provide ample bite with superb pedal feel. Combined with its adaptive suspension and wide grippy tyres, the X3 is a family car that’s also invigorating to drive, particularly when you select the ‘Sport’ mode.
The enhanced engine response and sharper steering that result (even the instrument panel display changes) make any twisting mountain road an engaging experience, enhanced by an intoxicating exhaust note that only a BMW M six can deliver.
The turbocharged engine offers an unyielding surge of acceleration from well below peak torque at 1900rpm to maximum power at 5500rpm, making BMW’s claim of 0-100km/h in a scant 4.6 seconds sound credible.
You can also manually change gears using the steering wheel paddles, but we found the gearing and shift calibrations so good that we preferred to leave it in auto mode.
However, the X3 M50 has two distinct personalities, as in more relaxed drive modes it’s just as happy serving as practical family transport during the week for grocery shopping, daily school runs and other common tasks.
It’s also a comfortable tourer for family getaways, with long gearing that requires only 1500rpm to cruise at 100km/h where low engine, tyre and wind noise allow highway conversations at lounge room levels.
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.
No ANCAP rating as yet but this X3 comes with a long menu of standard safety features including multiple airbags, AEB with pedestrian/cyclist/junction detection, front collision warning with brake intervention, lane-keeping, active cruise control, head-up display with speed sign recognition, front and rear cross-traffic alert, tyre pressure monitoring and lots more.
There are also ISOFIX and top tethers for the two outer rear seating positions.
Tested way back in 2019, an EQB 250 in Europe scored a five-star crash-test rating with EuroNCAP, and that result is accepted by ANCAP.
Safety features include Mercedes’ Driver Assistance Package that includes autonomous emergency braking, blind-spot monitoring with an exit warning that alerts the driver of approaching cyclists or vehicles if the door begins to open into their path, lane-keep assist and adaptive cruise control, as well as evasive steering and a ‘Parking Package’ featuring front and rear parking sensors and a surround-view camera.
The AEB with forward collision warning works between 7km/h and 200km/h, and offers pedestrian and cyclist protection day or night. The Active Lane Assist tech operates between 60km/h and 200km/h.
The EQB has nine airbags, made up of front, pelvis side and window bags for driver and front passenger, side airbags for rear occupants and a knee airbag for the driver, while the side curtains cover third-row occupants where relevant.
Along with a trio of child-seat tether anchorages, the EQB’s rear seat base is fitted with two ISOFIX attachments, and another two if the optional third-row chairs are present. That’s pretty rare, even in people movers.
Finally, the EQB makes a sound for pedestrians and other warns other road users that’s audible at speeds below 20km/h, plus a reversing tone.
It comes standard with a five-year, unlimited km warranty.
Scheduled servicing is determined by BMW’s vehicle monitoring system which advises when a service is needed, typically around 12 months/15,000km.
A capped-price servicing package covering five years/80,000km (whichever occurs first) totals $2475, or an average of $495 per service.
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.
