Lexus LX600 vs Range Rover Sport

What's the difference?

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.

Range Rover proudly calls it its “most dynamic” model ever, and based on our first experience that’s most definitely true. Its ability to be genuinely exciting to drive on a race track is nothing short of remarkable for a brand whose history is all about off-road prowess.

On the road it shines just as brightly, with its potent engine and state-of-the-art suspension system working in unison to make for a stunningly dynamic large and luxurious SUV. And then, if you need to cut across a field or scramble up a slippery hill, it will do that too.

Range Rover’s claims of ‘breadth of capability’ is apt but arguably an understatement. I’d stop short of calling the Sport SV the obvious class-leader in the high-end, high-performance SUV market because it’s up against some seriously impressive rivals, but the Range Rover offers a broader range of ability than any of its competitors.

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.

Range Rover is a brand synonymous with big, imposing and off-road capable SUVs, not dynamic and sporty vehicles. But in recent years the Evoque and Velar have added a new layer of style and a sleekness to the brand’s reputation.

The latest generation Sport is still a big and imposing two-tonne SUV, but it’s also definitely sportier to look at and the SV changes only add to that.

It only takes a moment looking at it and it’s clear this is an SUV that means business. The 23-inch wheels fill out the guards, the air-suspension can lower the body to the ground and the aerodynamic package, including the front splitter, make for a purposeful look.

The carbon-fibre bonnet can be finished with the centre section exposed, showing off the weave of the fibres, which is a nice touch, although fake vents on the bonnet and front fenders are a bit disappointing.

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.

There are two stand-out features in the cabin, beyond the standard high-level of luxury you expect from a Range Rover Sport. 

The first is the SV-specific steering wheel with illuminated paddles, which feels solid in your hands. But the second is by far the most interesting, the so-called Body and Soul Seats (BASS), which Range Rover has developed in conjunction with Coventry University.

Available with either genuine leather or ‘ultra fabric’ and a 3D-print knit trim, the seats look great on the outside but it’s what’s inside them that’s special.

There are four audio transducers integrated into the seat back which can vibrate to the beat of whatever audio track you’re listening to. The system uses AI to detect the lower frequencies and then work out which beats to transmit.

This is technology used by musicians, Coldplay’s Chris Martin reportedly wears transducers integrated into a vest when he performs, but Range Rover is confident it will add to the ownership experience.

It’s certainly an interesting technology and a demonstration across different music genres highlights the way the system adapts to individual songs, but it’s hard not to feel like this is more of a gimmick than something an owner will use every day. 

If you don’t like listening to music with it, the Body and Soul Seats also work with a ‘Wellness’ setting that features six audio pieces (designed by Coventry University musicians) - calm, soothe, serene, cool, tonic and invigorate.

It’s probably what you need to help settle your heart rate after you unleash the full performance potential of the Sport SV.

In the back seat there’s none of this technology but they do feature heating and ventilation as well as power recline functions. There’s also four-zone climate control, so every occupant can be comfortable.

To be blunt, the Range Rover Sport SV is one of those vehicles that if you have to ask, you can’t afford. Particularly in this case, as the model has launched in a single specification level, the Sport SV Edition One, which is priced from $360,800, plus on-road costs.

That puts it into the same financial category as the likes of the Aston Martin DBX ($356,512), Porsche Cayenne Turbo GT Coupe ($364,700) and Lamborghini Urus ($409,744) - especially when we discuss some of the pricier options.

For that price the Sport SV Edition One comes with exclusive branding on the front splitter, centre console, treadplates and puddle lamps as well as a raft of standard features likely to carry-over to the 2025 model year version.

These include carbon-fibre badges, forged 23-inch alloy wheels, digital LED headlights, a carbon-fibre bonnet, 16-way electronically adjustable front seats, Meridian 'Signature' sound system, 13.1-inch multimedia touchscreen, Apple CarPlay and Android Auto and newly developed ‘Body and Soul Seats’ (more on those later).

But if you’re feeling really sporty, you can upgrade your Sport SV with lightweight carbon fibre wheels and carbon ceramic brakes.

These will cost you a staggering $16,130 and $13,500, respectively, but the wheels measure 23-inches and are the largest fitted to a production car (and are also Australian-made by Carbon Revolution in Geelong).

Unfortunately, for now at least, this is all a moot point because Range Rover Australia has already invited and sold all examples of the Sport SV Edition One, so you'll need to be patient and wait until at least 2025 to have the option to buy one.

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.

Sadly the wonderfully evocative supercharged V8 engine from the previous generation Range Rover Sport SVR is gone.

But, thankfully, in its place is a more powerful engine that’s exclusive to the Sport SV in the Jaguar Land Rover family.

It’s a 4.4-litre twin-turbo V8 petrol engine with mild-hybrid assistance, which is actually built by BMW and based on the same powertrain as you’ll find in the M5, albeit with some specific Range Rover elements for more off-road capability.

It’s also more powerful than the old supercharged V8, making an impressive 467kW of power and 750Nm of torque, which is a 44kW and 50Nm improvement over the old engine.

It’s paired to an eight-speed automatic transmission, again with a specific SV calibration for improved performance. 

And, of course, being a Land Rover, it’s also got a four-wheel drive system with full off-road systems as well as an active locking differential.

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.

Despite all the extra power, thanks to the mild-hybrid system it’s more fuel efficient and produces less emissions than the old 5.0-litre V8.

Still, it’s all relative, and as you’d expect from a twin-turbo V8 SUV it’s still thirsty and uses 11.7-12.5-litres per 100km, based on European specifications.

The mild hybrid system uses a crank-integrated starter generator instead of a conventional alternator, providing a boost of up to 20kW and 175Nm of electrical power when needed, with the energy captured during braking and stored in a 48-volt lithium-ion battery.

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.

Before driving the Sport SV you need to understand its highly complex suspension system that allows it to be so dynamically capable. Range Rover calls it a '6D Dynamic' system, because it can control the car left and right, up and down and corner to corner. 

To achieve this the system uses a combination of hydraulic interlinked dampers, height-adjustable air springs and pitch control, which makes it a semi-active suspension set-up similar to the set-up Formula 1 race cars used to boast. 

This allows the Sport SV to sit between 10-25mm lower than the other Sport models and with its clever suspension can actually sit flatter in the corner with less pitch and roll - which is the traditional enemy of high-riding SUVs when it comes to handling.

But the suspension is only part of the story, with the intelligent all-wheel drive, rear-wheel steering, torque vectoring and the active locking rear diff all combining to produce an SUV with incredibly impressive dynamic capability.

Put simply, there’s never been a Range Rover that deserved to be driven on a racetrack. The Sport SV changes that, and thankfully the company let us loose on the challenging Portimao circuit in Portugal to put the SV through its paces.

Range Rover management was quick to stress it doesn’t expect the Sport SV to be a race track regular for its owners, but driving it on track did highlight the extreme potential it offers. 

With such a powerful engine it should come as no surprise that the Sport SV hauled down the straight, hitting 233km/h at the end of the long front straight, but with speed still rising which suggests its 290km/h claimed top speed is accurate.

Even from those speeds and with 2560kg of SUV to slow down, with the carbon ceramic brakes it was no trouble whatsoever. Instead the braking was strong and consistent across multiple laps. 

The steering is the particular highlight, with the rear-wheel steering helping to turn the Sport SV sharper and more quickly than a big SUV like this should. 

But while it impressed on the circuit, we also experienced it on some great winding rural roads across Portugal and this is where it shone even more brightly.

This is an SUV that you’ll genuinely enjoy driving with its ability to carve through corners and blast down anything resembling straight road.

But to ensure it lives up to the Land Rover badge on the front, we also drove it off-road. Nothing too serious at first, just muddy ruts, across some water and over some rocks.

But then we were guided through a course that showed off its articulation potential, which is far greater than the average owner will ever need. 

However, to achieve this Range Rover removed the carbon-fibre front splitter, so it’s not the most off-road friendly model the brand offers.

The Sport SV comes generously equipped with safety gear, as you’d expect at this price point. There’s all the usual passive safety, including airbag coverage for all occupants, and plenty of active safety including adaptive cruise control with steering assist, remote park assist and 3D surround cameras - which are used for off-roading as well as parking.

As with the rest of the Range Rover Sport range, it has been awarded a maximum five-star rating from safety agency, ANCAP.

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.

If you’re worrying about servicing costs, you’re probably shopping at the wrong end of the market, but as with the range-topping Range Rover model the price of the car is expected to include servicing for the first five years and roadside assistance for the same period.

It’s also covered by a five-year, unlimited kilometre warranty.

As with all Range Rovers the car will tell you when it needs a service depending on driving conditions. For example, if you hit the track or go off-roading it will likely need a visit quicker than if you're just commuting to and from work.
