Lexus LX570 vs Lexus LX600

What's the difference?

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.

There's absolutely no doubting the new LX's off-road credentials, nor the fact that it takes luxury SUVs to new heights in the four-seat Ultra Luxury model. Do you need a massaging chair and a foot-stool to get to your camping site? Probably not, but globally, there's a distinct market for that sort of decadence.

Closer to the other end of the LX line-up, however, there's a fair bit of cross-over in price and luxury terms with the Lexus' close cousin, the Toyota LandCruiser 300 Series. That suggests there might be a LandCruiser that will do the same job for a little less money and, if that's the case, then the LX loses a little relevance, particularly the petrol-engined version here in Australia. Until, that is, you take into account buyers for whom the Lexus badge infers the bank-vault solidity and prestige that the brand has worked so hard to establish. Which is another way of saying; it all comes down to where you stand on the politics of envy.

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.

Perhaps the most left-field design element is the way the LX can, depending on trim level, be configured in terms of its seating. In the past, we’ve seen plenty of SUVs available with a choice of five- or seven-seat layouts, but the LX is the first time we’ve seen seating choices range from seven- to five- to four-seat layouts. If nothing else, it illustrates the breadth of applications a modern luxury SUV is expected to cover.

Those who use their four-wheel drive SUVs off-road will also note the shift back to six-stud wheel hubs. Toyota’s (and Lexus’) move to five-stud wheels a few years ago suddenly made the vehicle’s wheels incompatible with owner’s existing caravans and trailers.

The new LX has also become a committed subscriber to the engine-downsizing theory of modern vehicle design. While the previous model was available with a 4.5-litre turbo-diesel and a massive 5.7-litre petrol, the new engine capacities of 3.3 litres for the diesel and 3.5 litres for the petrol represent major philosophy changes. Both the new engines are now V6s, rather than the previous V8 layouts.

And to give the new car a James Bond moment, all models bar the entry-level version feature a fingerprint sensor to control the starter button function. Q would be pleased.

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.

The practicality of each variant of the new LX is dependent entirely on how many people you need to move. The base-model version has seven seats with a two-three-two layout, while the Sport Luxury and F Sport feature five conventional seats in two rows.

The Ultra Luxury’s four individual seats obviously make it the variant of choice for the buyer who doesn’t need the extra seats, but clearly limit its appeal for families. But if luxury is your aim, the rear passenger seat in particular is the one to be in as it can be configured to offer up to a metre of legroom and even features a footrest when the front passenger’s seat is moved all the way forward. Both rear seats are also heated and cooled and reclinable to an angle that NASA has calculated offers the maximum support for the human body.

Vents in the rear seat area allow for an air-shower (of cool air over the passengers) or an air-curtain (a blanket of warm air at shoulder height).

The seven-seat versions have a third row of seats that folds flat into the floor (a major improvement over the old fold-up third row) and the second row folds and tumbles into the footwell. There’s a 220-volt outlet in the luggage compartment, too.

Cargo space is slightly less than the old model, but with second and third row seats folded, the LX has cargo space of up to 1871L.

The single-piece tailgate of the new Lexus won’t win as many friends as the old, split tailgate design which formed an impromptu kitchen bench or covered picnic seat. But the single rubber seal of the new design may be an advantage in keeping dust out on outback roads.

Much has been made of the Toyota LandCruiser’s $90K starting price in LC300 form, so it will come as no surprise to learn the new LX is likewise bold when it comes to the sticker on the windscreen.

The range kicks off in seven-seat form with the entry level LX600 (petrol) and LX500d (diesel) priced at $152,300 and $148,800 respectively. Of course, at these price points, entry-level is a relative term, and the list of standard features is a long one, indeed.

Lexus has gone for a tech-heavy look and feel here, with a 12.3-inch main display, a 7.0-inch lower screen as well as 8.0-inch multi-function display screen and even a colour head-up display for the driver. Lexus’ latest generation multi-media system is used, but may require some familiarisation for some owners.

The entry-level car also gets 20-inch alloy wheels, heated and powered front seats, leather-accented upholstery, a premium 25-speaker stereo system, LED headlights and active height control of the suspension via hydraulically-adjustable dampers.

Lexus has also fitted 'Multi-Terrain Select' and 'Multi-Terrain Monitor 2' to allow for different types of terrain and grip conditions as well as giving the driver a 360-dgeree camera’s-eye view of the track and the vehicle crossing it.

If that’s not enough, Lexus also offers what it calls an 'Enhancement Pack' which adds 22-inch alloy wheels, a sunroof and a kick-sensor tailgate for an extra $5500.

The next step up the LX ladder is the Sports Luxury model with a price-tag of $165,800.

For the extra money, you get a premium leather covering for the seats, and the front seats become heated and ventilated. There’s also a heated steering wheel, a cool box (much appreciated in Australia) a split rear-seat entertainment system and specific trim including timber veneer.

The new F Sport is next and adds not just more equipment but more capacity to the car’s off-road aspirations. That’s down to a Torsen rear differential which is torque-sensing in the way it distributes drive to each rear tyre, as well as performance dampers at each corner.

Dark exterior accents and a mesh grille help justify the F sport’s sticker of $171,800, as do interior touches such as seats with extra bolstering and some aluminium trim accents.

Which brings us to the headline act, the Ultra Luxury, which represents a huge price jump to $210,800. As well as extra equipment such as a rear touchscreen for climate control, wireless device charging, the Ultra Luxury is designed as a vehicle where the owner is more likely to be in the rear seat rather than the driver’s seat.

A strict four-seater, the vehicle has a pair of plush rear bucket seats (Lexus calls them captain’s chairs) which recline a full 48 degrees and feature a massage function. The passenger’s rear seat even runs to an ottoman and the entire cabin is trimmed in plush, quilted leather. Surely, with this layout, Lexus has achieved peak oligarch.

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.

While the Toyota LandCruiser 300 Series is a diesel-only proposition, the Lexus LX takes a broader view of what its buyers will want in such a vehicle.

As a result, there’s a choice of petrol or diesel power for the LX range, with both engines covering all variants apart from one. To add weight to the theory that the Ultra Luxury model is for people for whom fuel costs really don’t matter, it’s available only as a petrol vehicle.

The turbo-diesel engine is the 3.3-litre V6 twin-turbo unit we see in the 300 Series. It’s unusual in that it uses hot-side-in technology where the exhaust system and turbochargers live inside the vee of the engine, rather than hanging off each side as is much more common. Lexus claims greater efficiency from this layout with less plumbing between the cylinder head and turbo units as well as a more compact design.

Outputs for the turbo-diesel are 227kW of power, with an impressive 700Nm of torque produced anywhere between 1600 and 2600rpm, which is where the engine will spend most of its operating life.

The petrol engine is also a V6 and also twin-turbocharged. It measures 3.5 litres and, again, features a design that allows a smaller capacity engine to exceed the outputs of the physically larger, previous model. To that extent, it makes 305kW of power and 650Nm of torque; both impressive figures.

There’s only one transmission available on the LX, and that’s a 10-speed conventional automatic. To compliment that rugged, ladder-chassis design, the LX also has a transfer-case with proper off-road gear ratios. This is what gives the vehicle its rock-crawling and river-crossing abilities, while permanent four-wheel drive and the Multi-Terrain Select system mean no-fuss operation.

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.

Much has been made of the new LandCruiser’s fuel-tank reduction to its new total of 110 litres. The LX follows suit with an 80-litre main tank and 30-litre auxiliary tank, but it’s worth remembering the improved efficiency of the new drivelines will maintain the range to a useful total. The base-model diesel version also misses out of the second tank for an 80-litre total.

Toyota claims a combined figure of 8.9 litres per 100km for the diesel and 12.1 litres for the petrol. On the open road, both variants will get pretty close to those targets (even though they’re a combined urban-highway figure) so the touring range remains useful and better than 1000km for the turbo-diesel with the twin tanks.

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. 

Lexus surprised us a bit with its choice of test roads for the LX’s launch. As well as some twisty bitumen which might not, on the surface, have seemed the most LX-friendly terrain, the launch also threw in some steep if not otherwise too taxing off-road work.

The steep downhill section highlighted the fact that the LX has probably the best hill-descent control we’ve sampled. Not only is it simple to use with speed variation via the rotary knob that otherwise controls the drive modes, it’s also consistent and doesn’t stumble or lock-up wheels and bang brake calipers intermittently.

The second surprise was how well 2.6 tonnes of luxury off-road SUV handled the winding blacktop. It’s no performance-oriented SUV with its live rear axle and off-road-worthy suspension settings, but it can be hustled along in a pretty tidy manner if you concentrate and keep it flowing.

Beyond that, it was pretty civilised at everything else, too, and although it’s not a compact vehicle by any means, the cameras and sensors ensure that it’s not too much of a brain-teaser to park.

The LX seems to have slightly better noise suppression than the LandCruiser on which it’s based and the diesel version doesn’t seem quite as vocal under load. That said, it’s still very quiet and when rolling along at highway speeds and low engine revs, even the diesel is tomb-like in its silence.

But the petrol is next-level refined. There’s a small degree of engine raspiness when you rev the petrol V6 hard (and you won’t mistake it for a V8) but it’s a sophisticated soundtrack and, at a steady throttle, the petrol LX is even more silent.

The two engines have vastly different torque curves, but the 10-speed transmission is so on top of things that it can tailor its shift-pattern to make the absolute most of whatever torque and power are being produced. You can just feel the transmission holding a gear a little longer when the driver dials up max thrust, but in the interests of getting a heavy vehicle moving swiftly, using a clever transmission is the smart, modern way to do it.

Steering is a fraction light to be completely tactile, but that’s a function of the off-road abilities, and we’re pleased to report that the turning circle is very good given the exterior dimensions and makes tight city work much easier.

The shift paddles are, ironically, likely to be of most benefit when off-road and it’s here that the LX lays the SUV pretenders to waste. With low-ratio gears in the transfer case and that clever 10-speed, the LX will climb up some amazing places. It’s fair to say that, like all good off-roaders, you’ll run out of brave pills before the LX runs out of talent.

And while the suspension does a good job off-road, the live rear-axle and independent front suspension also combine pretty well on the blacktop. There’s some initial thump on pattery bumps that are felt more than heard. But as the bumps get bigger, the LX gets even better at dispatching them.

The variable ride height feels like air-suspension but is actually a clever hydraulic adjustment to the dampers to increase their length and, therefore jack the vehicle up for off-roading. Strangely, the ride seems to become a fraction firmer (and we mean a fraction) as the height cranks up, but most owners will never notice it.

What they will notice is the composure that the LX has in most settings. No, it’s not the fastest or tidiest handling SUV out there, but it’s well beyond good enough. And off-road? Very, very little is likely to touch it.

Lexus’ latest safety innovations have made it on to the new LX, and as well as the now-usual driver aids and passive safety gear, there are fitments such as an autonomous braking system that can identify cyclists in daylight hours and pedestrians any time of the day or night.

There’s also intersection turn-assist which minimizes the chances of a crash when turning across oncoming traffic, as well as emergency steering-assist to help with fast inputs in a crash-avoidance situation.

The adaptive cruise-control now also features curve-speed reduction if the car thinks a corner is being tackled at too high a velocity. Along with that is road-sign recognition, blind-spot monitoring, tyre-pressure monitoring, 10 airbags (12 in the Ultra Luxury) and Multi-Terrain Monitoring which allows for a transparent on-screen outline of the car, allowing the driver to see what’s around and even underneath the vehicle.

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.

Lexus Australia recently upgraded its factory warranty to five years/unlimited kilometres (up from three years). That’s better, but by no means a real advantage over most of its competition.

Capped price servicing is available at $595 per service for the first three years. The catch there is that servicing is every six months or 10,000km, an area in which Lexus trails its main competitors.
