BMW 740i vs Lexus LX570

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 Lexus is awkwardly big and not very fleet of foot when you're negotiating the commute to work, school or the shops. It slurps fuel at a rate we're not used to seeing these days and it's not the easiest to park, even with all of its cameras and beepers.

The LX is far more at home out on the highway, where it is incredibly comfortable and quiet. One imagines the diesel entry-level model would do it all, but with less consumption. If you must have a V8, the LX 570 without the S might be even more comfortable without the sports dampers.

Either way, it's a lot of car for the suburbs.

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 LX came in for a facelift in 2021, perhaps to differentiate it from its Toyota sibling and, according to the press release, “ its level of urban sophistication.” That kind of tells you where this car is going to spend all of its time, doesn’t it?

There’s the new spindle grille that dominates the nose, with some clever detailing to make it look a bit more sporty and dramatic. Around the car there are modified bumpers, skirts, new wheel designs, all that kind of thing. It does look sportier, but there’s no way to hide the visual bulk of such a big unit.

The interior is largely unchanged and the ruggedness is softened somewhat by semi-anline leather trim and alloy sports pedals. It’s terribly conventional and very usable, but there’s none of the excitement or innovation you'll find in other, more recent Lexus cabins.

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.

Hellooo?! I think there’s an echo in here. This is one giant car, with eight seats available for the keen or foolhardy to squeeze themselves into. If you’ve got all eight deployed, the boot space starts at a reasonable 349 litres. Kick out the three in the back row and flip them up to the sides of the boot and you have 710 litres, although that figure is slightly down on what it could be as the seats don’t stow neatly away under the floor.

Getting the third-row passengers out is a bit of a chore, because the middle row needs a hefty shove to move, while folding the third row jump seats is a power-assisted affair. The middle-seat passenger in the third row is hugely unlikely to be comfortable no matter their size, but the headroom is good anywhere you choose to sit, and the second row has heaps of legroom.

Scattered throughout are cupholders - I counted seven - and you get bottle holders in the doors. All three rows should be reasonably comfortable, with vents supplying climate-controlled air to each and everyone, and the middle row has its own set of controls.

When you’re knocking on the door of $170,000, “good value” is relative. You’ll be pleased to hear, however, that the LX 570 S is properly loaded. You get 21-inch wheels, air suspension, comprehensive multi-terrain modes should you feel the need to get out amongst it, terrain cameras (with under-car view), variable steering, auto LED headlights, auto wipers, powered tailgate, reversing sensors, reversing camera, clearance sensors, sat nav, head-up display, power front seats, four-zone climate control, heated front seats, wireless phone charging, around-view cameras, sunroof, heated steering wheel, and heated outboard seats in the middle row.

The 12.3-inch screen is big but it’s the old Lexus system, controlled by the weird mixture of touchpad and four-way rocker switch. It’s never been a satisfactory control method and the system itself is a little cumbersome, lacking Apple CarPlay and Android Auto.

The kids in the back should be sorted, though, with an 11.6-inch HDMI-input screen on the back of each front seat, and a set of supplied headphones so that, once the kids are plugged in, you can enjoy the 19-speaker Mark Levinson stereo in peace.

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 5.7-litre petrol V8 is classic Toyota/Lexus, unstressed and unhurried, with 270Kw and 530Nm. All of this is harnessed to an eight-speed automatic and an extremely capable off-road setup that almost nobody who buys this car will ever use.

The LX 570 S will tow up to 3500kg braked and 750kg braked.

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 official combined cycle figure of 14.4L/100km is fairly sobering but the real world is even more so - my time with the LX 570 S yielded an indicated 18.5L/100km, which was not unexpected given I spent a lot of time in urban and suburban driving. I don’t think that figure will come as a surprise to any owner of a 2600kg-plus petrol V8-powered four-wheel drive.

The LX 570 S has twin petrol tanks (93 and 45 litres) for a whopping 138-litre capacity to swallow 95 RON fuel, which, on my figures should deliver 745km between fills.

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.

First, some key figures - the LX 570 S is 5.08 metres long, 1.98 metres wide and 1.87 metres tall, depending on the height you’ve set the air suspension. It is Quite Large. Yes, cars like the Mazda CX-9 are as long and the Hyundai Palisade is nearly as tall, but given the LX’s humble origins, it just feels really, really big, and it looks it, too.

That feeling is not helped by oddly heavy and slow steering. The latter quality is a result of its off-roading abilities, but you can’t help but wonder if the variable-ratio steering couldn’t be made a bit quicker for town use. The S in the 570 S also adds sportier dampers front and rear, which do the ride quality few favours. Smooth roads are fine, of course, but concrete roads induce a weird porpoising movement that some air-suspended Land Rovers get, and it’s not particularly pleasant, although if you don’t use one of those roads, you won’t notice.

It's obviously a tricky machine to park and get around tight inner-city back streets. Our narrow suburban street posed a challenge when turning in and out of our narrow driveway with cars parked either side. And I did wonder about the strength of our driveway, given the heft of the LX.

I'm not going to pretend I enjoyed driving the LX, but it’s not bad to drive. You’re always aware of the sheer size and weight of the thing, though, as well as the conspicuous consumption of the very smooth and very agreeable V8. The engine does its best to shift the huge weight and the transmission is beautifully calibrated.

Once you’re on a motorway, progress is quite regal, too, so trips away in the LX will be supremely comfortable, even if you hit the busted-up dirt roads I accidentally ended up on. 

The LX has 10 airbags, ABS, stability and traction control, forward AEB (with pedestrian detection), auto high-beam, lane-departure warning, blind-spot monitoring, rear cross traffic alert and trailer-sway control.

The LX does not have an ANCAP safety rating. Its LandCruiser twin was last tested in 2011, so that’s not exactly relevant, given the huge rule changes and improvements in safety equipment since then.

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.

Lexus offers what I think is a unique four-year/100,000km warranty along with four years' roadside assist.

Capped-price servicing weighs in at $495 per service, almost $3000 over six services, and you'll be back at the dealer every six months or 10,000km before leaving with a loan car. Or the dealer will come and fetch the car from you and then return it freshly cleaned. Nice.

LX owners also get access to Lexus Encore Platinum . This generous program includes Lexus on Demand (you can book another Lexus - such as an LS or an RC F if you’re feeling racy - four times per year at some airports or dealers) and eight valet parking vouchers for some Westfields and Chadstone in Melbourne, all booked through the Encore app. There’s also a bunch of benefits inherited from the standard Encore program.
