BMW I4 vs Zeekr 7X

What's the difference?

If you’re intimidated by the electric future, don't be, because BMW’s i4 is just as good as any non-M sedan BMW offers right now.

The i4 delivers all the things you love about a 3 Series, engaging driving dynamics, a well-appointed interior and comfortable ride, but its all-electric powertrain means you’ll never have to stop at a servo again.

With a large battery on board, the i4 also serves up a decent driving range that should put anxiety-prone EV drivers at ease.

That is, of course, if you can get onboard with the looks.

The first thing that comes to mind in summing up the Zeekr 7X Performance is value. So much standard equipment for the money, stunning acceleration, top-shelf safety and a solid ownership package. It’s also practical, comfortable and the design inside and out is sleek. This electric SUV has thrown down a hefty gauntlet in challenging its existing opposition and there’s no doubt if you’re in this part of the market you should take a close look.

If the i4 looks familiar, that’s because it is based on the 4 Series Gran Coupe that entered showrooms last year.

This means a four-door liftback body style with a sloping roofline, athletic proportions and sizing close to the Tesla Model 3 and Polestar 2.

Let’s get it out of the way early and talk about the elephant in the room, the oversized front grille.

Say whatever you want about it, there’s no denying it gives the i4 a unique and head-turning look, and in my opinion, it’s not too bad.

In the flesh, it really isn’t as big as the press photos have made it out to be, and with the front numberplate to split it up, it does start to look a bit more like a traditional grille.

In profile, the 19-inch wheels fill out the arches well, and hide the massive brakes that add to the i4’s sporty appearance.

I particularly like the almost flush door handles that look futuristic, but aren’t as pretentious as those retractable handles you see on Teslas and Range Rovers.

Slim tail-lights and a chunky bumper inform the styling of the i4’s rear, but we’re really not a fan of a rear diffuser that keeps the exhaust cut-outs.

It makes sense on a model like the 4 Series Gran Coupe, but it just looks look rather odd on an all-electric model like the i4.

While the outside of the i4 might be all about that big grille, the inside is all about big screens, two of them in fact.

The instrumentation and multimedia screens dominate the experience inside, but BMW has also included physical buttons on the steering wheel and centre stack, as well as a rotary control knob, to make navigating the menus that much easier.

The connected screens differentiate the i4 from its 4 Series Gran Coupe relative, and make the cabin feel futuristic and befitting of the all-electric powertrain.

Overall, the i4’s styling might not be to everyone’s tastes, but BMW definitely gets credit for being bold in its aesthetic choices.

Would have been nice to see BMW’s designers go a bit further in differentiating the i4 from its 4 Series Gran Coupe cousin, but there's no denying the head-turning appeal of this all-electric sedan.

The 7X was developed at the Zeekr Design and Technology centre in Gothenburg, Sweden and arguably its most distinctive design element is the full-width band across the nose with standard LED headlights and DRL strip below. 

They’d be matrix units if we were in China and the black band would house Zeekr’s ‘Stargate’ panel capable of displaying words and digital animations. But ANCAP crash-test requirements put the kybosh on that for Australia and it’s been replaced by the black cover. But there’s still room to play with animations on the lights that remain, including musical accompaniment through internal and external speakers. 

Other than that, the car’s overall shape and proportions have a touch of Porsche Macan about them with a bulging mid-section and racy 21-inch rims filling the wheel arches.

There’s a slim, tail-light bar across the rear, a concealed wiper and an integrated spoiler on the top of the tailgate contributing to a smooth, clean look. No surprise, drag co-efficient is a slippery 0.25.

Inside, the fuss-free theme continues with a multi-layered dash design dominated by the 16-inch central media screen, compact digital instrument display and split-level centre console. And we’ll get to interacting with it all shortly.

Admirable restraint has been exercised in the simple surfacing and choice of trim materials with enough decoration to add visual interest.

As a premium mid-sized sedan, the BMW i4 offers up enough storage and space for most, but keep in mind there are limitations.

From the driver’s seat, everything is well placed and the electronically adjustable seats offer plenty of adjustability to get comfy for long road trips.

Storage options include an central cubby, glove box, two cupholders and small door pockets that just about fit a bottle, but the design means it rattles around a little.

Speaking of fiddly, between this car, and the weird plastic cowl thing found in the Z4 and 1 Series, BMW needs to be called out for some of the most annoying wireless smartphone charger designs.

This one is tucked all the way under a retractable lid, and is barely wide enough to fit some flagship-sized phones.

However, we will give BMW huge props for its iDrive8 multimedia system, which is displayed on a huge 14.9-inch screen.

The menus are clear, concise and intuitive, while the software is buttery smooth and responsive. It feels snappier than some phones we’ve used in the past.

Credit too for not making all inputs touch, as there is a rotary control knob and voice command capability available.

In the second row, things are a little more cramped, but at 183cm tall I can fit in the outboard seats with tight headroom.

There’s enough leg and shoulder-room, too, and passengers can make use of the climate controls, USB-C charging ports and a fold-down-centre armrest with two cupholders.

Opening the boot reveals 470 litres of volume, but fold the rear seats down and that pace swells to 1290L.

Loading large and bulky items is made much easier thanks to the liftback design, and it’s important to note i4 buyers aren't penalised in terms of practicality as the i4 and 4 Series Gran Coupe share the same boot capacity.

However, the charging cables can get in the way, as there isn’t any dedicated space for them.

The charging point is also in an annoying spot, in the right-rear fender where the petrol cap would be.

It means that you always have to reverse into charging spots, and it can be tricky to manoeuvre the i4 into just the right position to get the charging cable to reach.

The Nissan Leaf's front centre charging port, or the dual charging ports available on the left and right fenders in the Audi e-tron or Porsche Taycan are preferable.

So, before even getting in the car it’s worth talking about this Performance grade’s auto-opening doors.

The physical door handles are still present but inoperative (except in an emergency), so it’s a press of a button on the B-pillar, or a swipe card if you prefer, and open sesame. 

There’s ‘pinch protection’ for the windows on all side doors and impact avoidance which means it will stop short of denting your neighbour at the car park.

After a week of press-button experience I could easily live without this functionality but my significant other loved it. So, personal preference reigns supreme.

At close to 4.8 metres long, a touch over 1.9m wide and around 1.7m tall (with a 2900mm wheelbase) the 7X is a ‘large’ medium SUV and the interior reflects its generous external dimensions. 

There’s plenty of breathing space and a bright open feel thanks in part to the standard panoramic glass roof with power-sliding shade.

In the front, in terms of practicality, there’s a large, deep bin between the seats with a lid that opens from the left and right, another section with two swing-out cupholders and a roll-top lid, plus a big area in the lower console plus generous door bins. And there are handy flip-top boxes in the door armrests.

Worth noting on our test example, opening and closing the sliding cover over the cupholder section generated a groaning noise like oversize nails scraping down a blackboard, which didn’t exactly fit the premium vibe.

The glove box is opened with a button on the dash, which feels overly complicated. But then, in terms of power and connectivity there are twin 50W device charging bays and two USB-C sockets in the lower console.

In a big win for parents loading small kids into car seats, the rear doors open to 90 degrees. Then for storage, you’ve got map pockets on the front seat backs, decent door bins, two cup or bottle holders and a lidded box in the pull-down centre armrest, a small oddments tray at the back of the centre console and a pair of drawers under the seat.

And in the back, in terms of space, sitting behind the driver’s seat set for my 183cm position, I’ve got ample headroom, legroom and more than enough foot room. 

There are power window shades, individual ventilation outlets in the B-pillars to manage the climate control for the rear section as well as one USB-A and a USB-C socket in the armrest box.

And then, there’s the Occupant Monitoring System, a camera view of the rear seat which instantly does away with the awkward 180-degree parental head turn from the front seats. A small camera in the B-pillar is activated by a dash-mounted button for a wide-angle, picture-in-picture video image on the main media screen. 

And don’t worry, if you’re in the back and don’t appreciate the attention, a simple sliding cover over the lens can block the shot. 

With the 60/40 split-folding rear seat upright the 7X boasts 539 litres (VDA) of boot space, which is pretty handy, and that number expands to a hefty 1978L with the back seat down. 

There’s a load-through hatch, tie-down anchors, multiple bag hooks, specific lighting, a 12-volt socket and two storage compartments under the floor. The height of the power tailgate is adjustable but there’s no hands-free function.

Braked trailer towing capacity is 2.0 tonnes (750kg unbraked) and it’s worth noting vehicle-to-load functionality (using a specific discharge cable in the main charge port) is onboard.

But there’s no spare tyre of any description, with a repair/inflator kit your only option, which in this market isn’t good enough.

The Zeekr 7X starts at $57,900, before on-road costs, for the Single motor RWD version, rising to $63,900 for the Long range RWD and $72,900 for this Performance model.

At that money the 7X Performance lines up against a diverse group of primo EV SUVs like the Cupra Tavascan, Hyundai Ioniq 5, Kia EV5, MG IM6, Skoda Enyaq, Subaru Solterra, Tesla Model Y, Toyota bZ4X and VW ID.5. Not to mention its corporate Geely twin under the skin, the Polestar 4.

But cost-of-entry is one thing. The number of included features for the price is another and this car is properly loaded.

Aside from the performance and safety tech we’ll get to shortly the highlights are Nappa leather trim, 14-way power-adjustable front seats (with memory, heating, ventilation and massage functions), a leather-trimmed, heated and power-adjustable steering wheel, heated power-reclining (to 10 degrees) rear seats, a rear seat ‘Occupant Monitoring System’ (more on this later), a 16-inch multimedia display, 36-inch head-up display and digital instrument screen.

There’s also 2160-watt, 21-speaker audio, three-zone climate control, Android Auto and Apple CarPlay connectivity, multi-colour ‘Ripple Effect’ interior ambient lighting, all LED exterior lighting, auto door opening, a panoramic glass roof (with power sunshade), a power tailgate, heated and power-folding exterior mirrors, rear privacy glass (plus power sunshades) and 21-inch forged alloy rims. 

That’s heaps and there’s even more. Enough to put serious pressure on the competitors mentioned above.

If there’s one thing BMW knows how to do well, it’s building a sports sedan like no other. And that holds true for its EVs.

Powering this i4 eDrive40 is a single electric motor that produces 250kW/430Nm, which beats the outputs of even the 330i and 430i Gran Coupe.

With drive sent to the rear wheels, the i4 eDrive40 can accelerate from 0-100km/h in just 5.7 seconds, beating out the aforementioned 330i and 430i models.

For those that want a bit more pep, the top-spec M50 grade’s dual-motor set-up punches out 400kW/795Nm for a lightning quick 3.9s 0-100km/h run.

Compared with its petrol-powered 4 Series Gran Coupe counterpart, the i4 certainly puts up respectable figures, while offering more than a performance match for the Polestar 2 and Tesla Model 3.

The Zeekr 7X Performance is powered by dual electric motors, asynchronous magnet on the front axle and permanent magnet at the rear. Combined power is 475kW with peak torque at a grunty 710Nm.

That amount of muscle is up there at the top of the category with the likes of the MG IM6 Performance (572kW/802Nm), Tesla Model Y Performance (461kW/741Nm) and even the track-ready Hyundai Ioniq 5 N (448kW/740Nm).

With an 84kWh battery the official range on this i4 eDrive40 is pegged at 590km when tested to WLTP standards.

However, when fully charged, our test car's range readout was around 390km.

But keep in mind EVs aren’t as effective in cold weather, and the mercury was showing only three degrees on most days during this freezing Irish winter.

Luckily then, BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

BMW has included DC fast-charging capabilities in the i4 as standard, with its 210kW CCS plug able to take the battery from 10 to 80 per cent in around half an hour.

Using an 11kW AC charger however, will require 8.5 hours for a full charge.

In a week with the car, I averaged an energy consumption rating of 23.4kWh per 100km, almost matching the official figure of 22.2kWh/100km.

My driving included several long-distance trips on the freeway, however, an environment in which an electric vehicle does not excel.

Worth noting the heavier and more energy-hungry M50’s official driving range drops to 510km, but we’re yet to test its real-world figures.

The 7X boasts an 800V electrical architecture which means it has 420kW charging capability and even though the max public charging output currently available here is 350kW, at that level you can expect the 100kW NMC battery to charge from 10 to 80 per cent in around 13 minutes. AC charging is a handy 22kW for 10-100 per cent charging in four hours.

Claimed (WLTP) range is 543km and on test we saw average energy use of 18.8kWh/100km, which is in the middle of Zeekr’s claim of 17.7-19.9kWh/100km for the combined (urban/extra-urban) cycle and more than acceptable for an EV of this size and weight.

If you came here just to find out whether BMW has succeeded in transplanting its signature sports sedan characteristics into the all-electric i4, the answer is, yes.

The best thing I can say about the i4 is that, aside from the way power is delivered and the lack of engine and exhaust noise, it feels just like a 3 or a 4 Series.

Steering is sharp and responsive, throttle and brake inputs are immediate, making this rear-drive i4 a delight to drive enthusiastically.

The staggered Michelin Pilot Sport 4 tyres and massive brakes obviously help in this regard, and look, it’s not as sharp as the Porsche Taycan, still the sharpest electric vehicle we’ve driven to date, but the driving experience in this i4 is comparable to the excellent 3 Series.

But I’m not in love with the fake sound piped into the cabin when in 'Sport' mode. It sounds weirdly low-rent and I much prefer to accelerate to triple digit speeds in serene, near-silence.

Switch things up to 'Comfort' mode, and the i4 makes for a surprisingly relaxed drive.

The steering gets bit a looser and the adaptive dampers ease off a little, soaking up bumps and road imperfections with minimal affect to occupants.

Pair this with the nearly-silent electric powertrain, and well, our little one in the back seat has fallen asleep on more than one occasion in my time with the car

You can also adjust the level of regenerative braking in the i4 and operate it with one pedal like in the Nissan Leaf and Hyundai Ioniq 5.

This is a more efficient way to drive an EV as it forces you to look ahead and be careful with your throttle inputs.

One-pedal driving might not be for everyone, but it’s nice to have the option there.

So, even at around 2.5 tonnes, with all that power and torque under your right foot, the 7X Performance can rocket from 0-100km/h in a supercar-like 3.8 seconds. It is properly quick.

Suspension is by double wishbones at the front and a five-link set-up at the rear and the hefty body is well-controlled in the main, although you can feel modest lateral movement on quick changes of direction. 

The ‘Continuous Control’ air suspension has three settings - Comfort / Standard / Sport - with a distinct difference between them.

In Comfort, small bumps and ruts still make their presence felt, but overall ride compliance is impressive. Hot tip is to avoid the Sport mode unless you’re determined to press on through your favourite set of corners, or (implausibly) line up for a track day.

The 7X rides on Zeekr’s ‘SEA’ (Sustainable Experience Architecture) platform which features an integrated alloy diecast rear section which seemingly makes a ‘solid’ contribution to overall refinement and noise reduction.

Speaking of which, wind noise is close to imperceptible even at freeway speeds, helped in no small part by the car’s slippery drag coefficient.

The accurate speed-sensitive steering delivers good road feel, which isn’t always the case with larger EVs, and the big 21-inch (265/40) Continental EcoContact 7 tyres are pleasingly quiet while gripping with reassuring determination.

Braking is by ventilated discs all around with chunky four-piston calipers up front. There are two levels of regenerative braking and a ‘single-pedal’ setting, although the latter is best treated as a third regen level because it seems reluctant to bring the car to a full stop quickly enough, even in slow-moving traffic.

Important to mention crash-avoidance safety aids like lane-keeping assist and driver fatigue monitoring don’t intrude unduly. There are subtle occasional vibrations through the steering wheel and only when necessary. 

You’ve also got a 360-degree overhead view and a good quality reversing camera, both of which are super-handy when manoeuvring. Or if you want some real assistance ‘Automatic Park Assist’ will help you slot the car into the space you’re aiming for, as well.

Ergonomically speaking, while there’s a physical control for audio volume something like exterior mirror adjustment for example is via the combination of a screen slider and a steering wheel control which is fussy. That said, progression through screens and functions for media and car settings is logical and quick thanks in part to a grunty Qualcomm Snapdragon chip platform.

Under the heading of miscellaneous observations, an 11.6m turning circle is useful for a car of this size, the mega audio system cranks (with the driver’s headrest speaker a highlight) and the adaptive cruise works well, picking up acceleration rapidly when pulling out to overtake a slower-moving car in front.

While the 7X hasn’t been assessed by ANCAP yet it’s fair to assume a maximum five-star result sooner rather than later, in line with its Euro NCAP score. 

And crash-avoidance safety tech is through the roof. Fifteen key ADAS functions including adaptive cruise, auto emergency braking (AEB), blind-spot monitoring, front and rear cross-traffic alert, lane keeping assist, a parking assist system and more. There are 12 hi-def cameras, 12 ultrasonic radars and a millimeter-wave radar on the job.

The airbag count runs to seven, including a front centre bag, and there are three top tethers for child seats across the second row, with ISOFIX anchors on the two outer positions. And a big tick for ‘Post-Impact Braking’ designed to minimise the chances of subsequent collisions after an initial crash.

Suffice it to say the 7X Performance sits on the top safety shelf.

Like all BMWs sold in Australia, the i4 comes with a three-year/unlimited kilometre warranty with roadside assist over that period.

This falls short of the now-standard five-year assurance periods offered by premium rivals Audi, Genesis, Jaguar, Lexus and Mercedes-Benz.

Scheduled servicing intervals for the i4 are every 20,000km/24 months, at least in overseas materials.

Australian intervals are yet to be confirmed, but BMW is offering service price plans covering four- and six-year periods in 'Basic' and 'Plus' forms.

The Basic plan for four and six years is set at $1240 and $1765 respectively, while the Plus package is $4805 and $5500.

The 7X Performance is covered by Zeekr’s five-year/unlimited km warranty, with eight-year/160,000km cover for the drive battery, neither of which are exceptional for the category. But there’s also five-year corrosion and paintwork warranty cover, with roadside assist included for the same period.

Recommended maintenance interval is two years/40,000km with optional health checks in between. Stick to the basic schedule and you’re looking at $1755 over the first five years.

Go for the complimentary first year service plus two other optional health checks and the figure is $2385, or an average of $477 per workshop visit over the same five years. Far from over the top for an EV in this part of the market.

The Zeekr dealer footprint currently takes in multiple sites in Brisbane, Melbourne and Sydney with additional locations in Canberra and Perth as well as The Sunshine Coast and Geelong, for a total of 14.

Some are currently ‘pop-ups’ with the intention to transition them to permanent status, with all dealers able to facilitate servicing (on site or at a separate location).
