BMW 740i vs Mercedes-Benz EQB250

What's the difference?

While the new 7 Series won’t visually appeal to everyone, nor is it at the forefront of spirited driving dynamics, it’s hard to argue that it isn’t fit for purpose.

Its rear theatre screen and lounge layout might seem gimmicky at first, but it’s difficult to think of a more comfortable way to be transported on wheels short of putting a chassis under your loungeroom. Even then, you’d have to ask someone for a massage.

This is one of those cases where a car becoming larger isn’t such a bad thing, and BMW should feel like it’s achieved, seemingly, what it set out to do in building an electric limousine that doesn’t fall short in range or dynamics.

If BMW can bring this level of refinement down to its more affordable models, its electric future is looking promising.

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.

BMW freely calls the new 7 Series “monolithic” in its press material, and it’s hard to argue. The seventh-generation of its luxo limo is bigger in every dimension, and with a higher bonnet and bootlid, the car is convincingly imposing even when parked. Even more so in black.

From the front, the 7 Series clearly has a new face compared to its predecessor, with split headlights now an indicator of BMW’s luxury oriented models - the incoming XM SUV features the same.

Its LED daytime running lights feature Swarovski crystals, while the grille surround illuminates while the vehicle is parked and on. It’s currently unable to be illuminated while driving to comply with Australia’s laws.

It’s perhaps less elegant and more aggressive than previous generations, but that doesn’t mean there won’t be those who approve. It’s certainly emotive, especially when compared to the side and rear of the car.

The side profile of the 7 requires quite a few steps back from the car to really take in - it’s almost 5.4 metres long - though it's hard to hide the size of a car that allows its rear passengers to almost lay down.

From the rear, the 7 Series is probably at its most uninspiring, which is a reverse from the interior where the front feels more minimalistic than some of its rivals like the Mercedes-Benz S-Class.

BMW has used crystalline geometric shapes throughout the cabin, and the front ‘interaction bar’ is perhaps the best example.

In keeping with the minimalism, its screen sits in an almost freestanding style out from the dash, with no physical buttons seen around it.

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.

If the word ‘practicality’ brings to mind simplicity, the 7 Series might require you to have a bit of a mental reset. If it means plenty of space and a long list of elements to keep you comfortable, you’d be closer to the money.

While it’s visually restrained in some ways, the space accessible to the driver is thought out reasonably well, as you’d expect from a car costing more than a quarter-million.

The front seats certainly aren’t the main event, but the Merino leather and cashmere wool combination seats are far from uncomfortable, with the heating, cooling, and massage functions accessible from the central multimedia screen.

The controls for those, as well as functions like the climate control, are easily accessible, though could probably be even easier with a physical climate control panel. 

Controls for the individual vents, and even the glovebox are found along the BMW interaction bar, which can (frustratingly) reflect light thanks to its crystalline design, meaning it’s hard to see while driving on a sunny day.

Similarly, while the centre console where the main control dial for BMW’s 'iDrive' isn’t far removed from previous versions, it’s less tactile and requires a look sometimes to see what’s being pressed. Here, too, sunlight can reflect (this time off the dial) and make it more distracting.

Fortunately, the steering wheel controls remain physical buttons, and they’re laid out in a way that previous BMW owners or drivers will find familiar. 

The 7 Series also now leans more heavily on voice activation, so if the lack of physical climate controls or the multimedia screen is a little distracting, much can be achieved by actually asking the car with a “hey, BMW… ”.

There’s a large storage unit in the centre console, as well as two cupholders and a phone charging platform in front of the multimedia controls.

The rear seats, especially the one behind the front passenger, are where the 7 Series begins to feel its worth. If you’re buying one with the intention of being the driver 100 per cent of the time, you’re missing a trick.

The ability for the front passenger seat to shift forward and maximise legroom while the rear seat reclines into a lounge position is nothing new, limousine sedans have been able to do this for years, but the 7 Series takes it to another level.

Not only is there plenty of space for even the tallest of humans to stretch out, but the positioning and angle of the huge 31.3-inch theatre screen is great, even if it impedes the driver’s rear view, and the ability to use it as a touchscreen for some functions means less need for the handy but sometimes fiddly door-mounted control screen.

If you plan on playing games, the controls (and the fact you’re likely in a moving car) can make it a little difficult, but the small control panel is overall easy to use and well-placed.

The cushioned armrest that folds down in place of a middle passenger is comfortable, features a phone charging pad and pop-out cupholders, as well as a storage space under the armrest.

Finally, the boot space in the BMW 7 Series is far from small, with the electric i7 offering 500 litres (VDA) of space, while the 740i boasts 540 litres thanks to its lack of battery.

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.

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.

The BMW 740i is powered by a 3.0-litre turbocharged in-line six-cylinder petrol engine, as is the way with many of BMW’s larger cars. It’s also a mild hybrid, incorporating a 48-volt electric starter/motor combination.

The 740i makes 280kW between 5200-6250rpm, and 520Nm between 1850-5000rpm, which is transferred to the rear wheels via an eight-speed automatic transmission.

The electric i7 xDrive60 is the flagship model, with its dual-motor all-wheel drive powertrain good for 400kW and 745Nm, allowing for a claimed 0-100km/h time of 4.7 seconds - 0.7s faster than the 740i.

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 Australia hasn’t yet specified local figures for fuel consumption or energy efficiency for either variant of the 7 Series at the time of our review, but the international specifications for both i7 xDrive60 and 740i give a relatively accurate guide.

BMW claims the electric i7 has a power consumption of between 19.6 and 18.4kWh/100km, which means its 101.7kWh battery allows a range of between 591 and 625km according to the brand.

It’s claimed to charge from 10 per cent to full in less than 5.5 hours with a 22kW AC wallbox, or in 34 minutes to reach 80 per cent using DC fast charging at 195kW.

The petrol powered 740i will use between 7.0 and 8.0 litres per 100km, according to BMW, which equates to between 183 and 159g/km of CO2.

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.

BMW hopes for two things for the new 7 Series: one, that it’s the best car to be driven in, and two, that it’s the best car to drive.

While one of those things could be argued to be true, we suspect there are some engineers in BMW’s M department who would be frustrated at the thought of a more-than 2.6-tonne limo being called better to drive than a car half that size with a manual gearbox.

But, perhaps unsurprisingly, the BMW 7 Series is rather refined from the driver’s seat, especially on roads where the speed limit is high and the corners are long.

The two variants Australia has available, the i7 xDrive60 and the 740i, differ in their drivetrains as mentioned above, and the dynamics of each are slightly different. 

The all-wheel drive electric i7, despite its extra heft (the 740i is almost 600kg lighter) the EV feels more nimble thanks to its immediate torque delivery and higher outputs give it more flexibility in dynamic driving.

The lower centre of gravity, even with the extra weight, helps the electric i7 hold its own against the turbo six-powered 740i.

Both variants come standard with BMW’s rear-wheel steer system, or ‘Integral Active Steering’, which is vital to providing the agility needed for keeping the 7 Series in shape on tight roads, where it tightens the turning circle below 60km/h, though its 3215mm wheelbase does a lot to keep it feeling stable.

Above 60km/h, the rear-wheel steering improves stability further by turning slightly with the front wheels as opposed to against them, allowing for smoother flowing cornering and highway lane changes.

In either case, the 7 Series is easy to drive, with the steering able to be set to Comfort regardless of the drivetrain’s intensity (Sport and Comfort are the only options), which leaves the wheel feeling lighter.

The ride, whether from the front or the back, is impressive, even when being chauffeured through rough backroads. 

The 7 Series, despite not being engineered specifically for Australia’s sometimes shockingly pockmarked roads, manages to soak up impacts before they transfer from the tyre into the seats, and that goes for the sound and road noise, too.

Unfortunately, our launch test drive was hampered by some roadworks out of BMW’s control, so stay tuned for a more in-depth drive soon.

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.

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.

BMW offers a five year, unlimited kilometre warranty and that extends to both variants of the 7 Series.

BMW also offers servicing packs for its new cars, though the pricing for each group of models excluded the 7 and 8 Series and its M cars. 

Given the most expensive servicing pack listed is the BMW X7’s $2800 five-year, 80,000km pack, expect anything similar for the 7 Series to cost more.

In terms of when servicing is required, BMWs are condition-based, meaning the car’s own systems detect whether something like an oil change or part replacement is required, and provides that data to your BMW service centre to help calculate an estimate for work needed, ahead of time.

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.
