Lexus LX450D vs Lexus LX570

What's the difference?

If you're in the market for the best-of-the-best SUV wagon, then you could do a lot of worse than get in a LX 450d. It looks good, is packed with standard features and is supremely comfortable. The 450d also has an suite of safety tech worthy of the hefty price-tag and it works well as a daily driver and has plenty of touring potential, even though we doubt it'll ever get anywhere near achieving those claimed fuel-consumption figures with real-world usage. Sure, you could instead climb in a second-hand, well-looked-after, never-been-off-road LandCruiser 200 Series and spend the money you save, by not buying this new Lexus, on aftermarket and camping gear, camping fees and also hiring a team of four people to follow you on mopeds everywhere and constantly tell you what a great driver you are – but that's not the point with vehicles of this ilk. They may not be aimed at hard-core off-roading buyers, but they are cushy, classy, and cityified – and, in that respect, they're incredibly well-built for purpose.

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.

It has that signature Lexus jagged space-age grille, chunky shoulders and beefy back end that suit a luxury SUV dreamed up by folks craving a significant presence and plenty of attention for their product.

Bulky side-steps, an upswept raked profile, scalloped side panels and moon roof all top what is a cool combination of eye-friendly design factors. It's a slick mix of low-level cool and high-end style.

Take a look for yourself and make up your own mind whether you like it or not.

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.

It certainly feels like Lexus designers and engineers have maximised every last millimetre of interior space; there is stacks of room inside with plenty of real-world usable storage spaces, including cup-holders, door pockets and spots for keys, phones and other stuff.

The heated steering wheel, stylish analogue clock, wireless charger, Lexus climate concierge (coordinating all four-zone temperature controls), cavernous centre-console cooler box, and rear-seat entertainment system are all nice touches but pretty much assumed at price-points lower than this one.

The 12.3-inch high-definition media touchscreen is clear and bright and easy to operate, but the Remote Touch Interface, the control near the shifter, is very annoying to use. The toggle/selector is too sensitive, skipping past your actual choice over and over again, while you try to manipulate it just so, so it lands on the option you wanted.

The second-row seating is plush and the seat sections are easily slid forward and tilted.

Lexus claims the 450d offers 909 litres of cargo space if there are five occupants; and 1431 litres if there are only two occupants. If you have some casual weekend touring in mind, with a spot of camping, then this Lexus should cope with your gear, no worries.

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 Lexus LX 450d has the LandCruiser's 4.5-litre twin-turbo direct-injection V8 engine, producing 200kW@3600rpm and 650Nm@1600-2800rpm. All of that power and torque arrives evenly and smoothly, helped no end by a slick six-speed sequential-shift transmission.

It has a full-time 4WD system, dual-range transfer case and off-road tech that includes multi-terrain anti-skid brakes, crawl control and a four-camera multi-terrain monitoring system with back guide and panoramic view. 

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.

Lexus claims the LX 450d will achieve a 9.5L/100km figure from combined-cycle driving (that's 4.9L/100km more frugal than the LX 570 is capable of). Lexus reckons, based on that figure, that the diesel LX has a potential range of almost 1000km on a full tank (93 litres) of fuel.

We recorded 12.7L/100km during daily driving (city and suburbs) and 13.5L/100km with some light off-roading thrown into the drive mix.

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.

It’s supremely comfortable and very quiet, wth that customary cocoon-like enclosed sensation that you only ever truly get in a vehicle this far away from cheap.

The 450d is 5080mm long, 1980mm wide and 1865mm high. It has a 11.8m turning circle. It has an official kerb weight listed as between 2510kg and 2740kg.

For something with so many kegs onboard, it’s capable of punching off the mark with a respectable bit of pace; handy for city-street bursts to slip through traffic gaps.

It never feels cumbersome; it actually feels quite light on its toes. In fact this Lexus tends to be more than a little bit floaty at times. You can select different suspension settings – comfort, normal or sport – to suit your preference.

Visibility is generous all-round with clear sightlines in all directions; besides, the reversing monitor with 360-degree view helps if your views are hindered.

Steering is generally active but it does exhibit quite a lot of under-steer on twisting country roads. It has paddle-shifters if you’re that inclined.

The LX 450d rides on 20-inch alloys and 20-inch Dunlop Grandtrak PT2As (285/50F20 112V) – a combination which is fine for bitumen-based outings, but we’d ditch it for rubber with more sidewall to allow for greater freedom to adjust tyre pressures to suit rough terrain.

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.

Warranty is 4 yrs/100,000km. Service intervals with indicative pricing (exc GST) are: six months/10,000km: complimentary; 12 months/20,000km: $535.56; 18 months/30,000km: $598.11; 24 months/40,000km: $800.32; 30 months/50,000km: $502.44; 36 months/60,000km: $676.23.

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.
