BMW 740i vs BMW IX

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.

If anyone was worried that it would be too late to get a decent bit of value out of an entry-level iX, there's reassuring news.

With more power, range and features added to the model and the cost remaining close to its former sticker price, the iX has held up well despite now existing in a more competitive environment.

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 iX was a bit divisive upon its original launch, because it was one of the early adopters of BMW’s current ‘big grille’ era.

The good news for the iX is that many have adjusted their expectations on that front and it now feels pretty well at home in the brand’s line-up.

The addition of the 'Iconic Glow' grille surround might be a step too far for some, but overall the iX has aged well and its exterior design hasn’t changed much because of that.

The adaptive LED headlights have new DRL elements, and the M Sport pack is now standard, but if you were only casually familiar with the iX you’d have to be looking closely to spot the update.

The new colour palette for the iX also includes the pictured 'Arctic Race Blue metallic', though I’m personally a fan of the iX in all black, giving it a more monolithic look.

Inside, it’s a similar story - what was once perhaps ahead of its time is now the expectation in an electric SUV. Minimalism in terms of physical controls, but plenty of space.

Helping the feeling of spaciousness is the now-standard panoramic sunroof, though a lack of physical shade is one of the iX’s few interior let-downs. Instead, it can electrochromatically ‘shade’, which still lets in plenty of light.

At night, ambient lighting joins the glow of the iX’s rather large 14.9-inch multimedia touchscreen and 12.3-inch driver display.

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.

The space on offer in both rows of the iX is a huge plus, and it might even be enough to make you look past some of the small downsides to the electric Bimmer’s interior.

The iX’s clever two-level central console has the phone charger pad and drinks holders down out of the way and means you can put distractions (phone) and your tall bottles out of the way. There's a slot above for your phone to sit upright with a gap under for charging, too.

The storage bin under the armrest also has plenty of space as well as a little shelf for smaller items you don't want to go hunting for, but the iX’s control panel and dial are still reflective and, at certain times of the day, this means distracting light getting in your eyes. 

Speaking of distracting, I have found BMW’s multimedia software to be less intuitive and more complicated with each major update, and ‘OS 8.5’ is no different. At this point, using the brand’s touchscreen feels like operating an iPad on the move, with dozens of menu tiles to sort through.

But back to the physical space that is the iX’s interior - the big EV makes a lot of sense as a family car, especially if your kids are old enough to appreciate (and keep clean) the fit and finish.

Not only does the drive have a nicely adjustable and comfortable sports seat thanks to the M Sport pack, there's also heating and a massage function.

The front passenger gets the same, and the second row is borderline palatial. There's heaps of kneeroom, headroom, and even space under the front seats at their lowest setting to slot your feet.

The four-zone climate controls mean arguments are avoided, there is of course a central armrest, though even with it folded up and a person in the centre there's enough room in the back to be comfortable. 

Behind that, the iX’s 500 litres of boot space could probably be expanded but at the expense of rear legroom, so it's acceptable. There is space under the floor for cables, but no space saver spare, just a repair kit.

There's a switch that allows you to fold the seats down from the tailgate, but you can also manually fold the middle seat for a 40/20/40 split rather than the more expected 60/40.

The sole entry-grade iX is the xDrive45 M Sport, which brings with it more than the original base xDrive40, but also a price a few thousand dollars higher.

It starts from $142,900 but can quickly become much more expensive when you start ticking options boxes. But in this market segment, it's not that unusual, especially considering recent arrivals like the Polestar 3. 

Given it’s only a little more expensive than before, the extra kit and higher grade that now forms the iX entry-point is impressive.

The 'M Sport' pack is now standard as the name suggests, plus there’s M trim inside like the steering wheel, the M seats and silver design highlights.

The LED lights are now adaptive and the glowing grille surround has also been added.

There’s also now a panoramic glass roof as standard, rather than an option, plus the steering wheel is heated and there’s now a tyre pressure monitor.

Aside from that, there’s plenty that carries over, like the wireless phone charging, wireless Android Auto and Apple CarPlay, 18-speaker surround sound by Harman Kardon, four-zone climate control and heated front seats.

There’s also an 'Executive Pack' which adds some comfort features like soft-close doors, privacy glass and front seat ventilation with rear seat heating. That one’s $6500.

Then there’s active steering, which brings the rear wheels into play for more manoeuvrability and stability for $3000.

Adaptive air suspension is $4000, while the most expensive option is a 30-speaker Bowers & Wilkins ‘Diamond’ surround sound system for $9500.

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.

The iX has, as the xDrive part of its name would suggest, a dual-motor electric set-up with all-wheel drive. 

Power and torque now total 300kW and 700Nm for the system in the xDrive45 M Sport, up from the 240kW and 630Nm on offer in the outgoing xDrive40.

BMW says the iX is now good to hit 100km/h from a standstill in 5.1 seconds, with its claimed top speed a nice, rounded 200km/h.

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.

The iX’s 94.8kWh battery allows a range up to 522km, but relatively low efficiency because of the size and weight.

Its 20kWh/100km is on the higher side of power use for cars around this size and this is part of the reason its huge battery capacity results in a fairly average driving range.

Maximum power input for DC fast charging is, however, up from 150kW to 175kW with the update, which is good news for those long drives.

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 BMW iX was a relatively early entry into the catalogue of electric cars I’ve driven and because of that it had a couple of (in hindsight) unfair criticisms levelled at it.

For a start, it felt heavier than expected and its ride quality didn’t feel up to BMW’s standards - both things that plenty of electric SUVs have struggled with since.

But its drivetrain, design, and interior all impressed, aside from perhaps some of the aforementioned interior reflections.

Now years on, and the iX has aged well.

Some of the mechanicals and suspension also copped a tweak along with the entry iX now being a more powerful ‘45’. The result is a big electric SUV that holds up better than I remember.

‘Smooth’ is the key word that comes to mind in regards to a lot of the iX’s characteristics. While it’s still not perfect and feels heavy, the iX rides well in comparison to many SUVs on the market, including some of its close rivals.

Perhaps key to this is the fact its standard 21-inch wheels leave plenty of tyre to help the suspension soak up sharp edges on bumps, while we’re sure BMW’s handling engineers have learned more about getting the best out of a big, heavy electric vehicle in the last couple of years.

Road noise is well-muted as a result, and the shape of the iX doesn’t seem to lend itself to excessive wind noise. Even when you’re getting rather quick.

Despite being a 2525kg beast, its 5.1-second sprint to 100km/h is in the muscle car realm - the last of Holden’s V8 Commodores would do about that, for reference.

Its acceleration is also nicely progressive, rather than giving you an almighty but unnecessary jolt of torque right as you put your foot down. But once there’s traction and you’re rolling, the xDrive45 is impressive.

Meanwhile, its cornering and braking still reveal the heft behind the iX, it’s not something you can chuck around like a go-kart, but that’s also not really its area.

Anyone familiar with BMW’s steering characteristics will find the slightly higher force required for its weight (and thickness of the steering wheel rim) standard, though it’s still unnecessarily on the heavier side.

The BMW iX holds a five-star ANCAP rating, which it earned under slightly more lenient testing back in 2021.

Seven airbags, auto emergency braking with cyclist and pedestrian detection up to 80km/h, lane-assist, rear-cross traffic alert and intersection assist, plus a surround view parking camera all help immensely.

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.

BMW offers a five-year/unlimited kilometre warranty with an eight-year/160,000km warranty on the battery.

BMW servicing takes place as needed rather than on a schedule, meaning you’ll be alerted via the car or app when a service is required in the near future.

For the iX a six-year all-inclusive service pack costs $3475, regardless of how many km you drive.

BMW has 54 servicing dealers listed in Australia, with each capital city covered and many more locations in the eastern states.
