Cadillac Lyriq vs Lexus LX600

What's the difference?

The Lyriq Luxury combines handsome styling and luxurious appointments with responsive yet supple ride quality, the choice of relaxed driving or exhilarating performance as desired and a decent driving range. Its lack of towing ability may be a deal breaker for some, but it's certainly worthy of consideration by prestige SUV buyers with a penchant for electric power and (for now at least) sub-$100K drive-away pricing.

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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The Lyriq has a generous 3095mm wheelbase, is more than five metres long (5005mm) and almost two metres wide (1977mm, including mirrors). Its 1620mm roof height is relatively low for a large SUV, resulting in a sleek and sporty profile combined with a muscular surefooted stance fronted by a finely-etched solid grille.

It rides on five-link independent suspension with GM’s ‘passive plus’ dampers, plus there’s electric power-assisted steering and big Brembo disc brakes in each corner featuring classy Cadillac scripts on the calipers. Turning circle is 12.1 metres, which is to be expected for a car of this size.

The interior design is an elegant blend of soft-touch materials and discreetly textured surface finishes with an emphasis on chrome and satin chrome highlights. It’s also spacious as you’d expect, with the panoramic sunroof creating a bright and airy feel.

We applaud Cadillac’s adherence to tradition with physical buttons and knurled dials and knobs for controlling key cabin and driving functions, in preference to annoying and distracting touchscreen menus. There’s also nice attention to detail with small jewel-like Cadillac emblems and scripts contributing to its prestige look and feel.

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.

The Lyriq’s 2687kg kerb weight (largely due to its hefty propulsion battery) and 3200kg GVM results in a modest 513kg load capacity, which could easily be used up by five large adults before you could think about loading their luggage. It’s also not rated for towing in Australia which limits its appeal as a recreational vehicle.

Driver and front passenger enjoy palatial space and comfort plus ample storage with a bottle-holder and bin in each door. There's also a large glove box, pop-out drawer in the dash and a ‘floating’ centre console equipped with a lower tray, three USB-C ports, a 12V socket, wireless phone charging and a felt-lined box at the back with padded lid that doubles as an elbow rest.

The rear doors open wide for easy entry to the rear bench seat which even for tall people (I’m 186cm) offers ample room for knees and feet, enhanced by a flat floor with no transmission tunnel for centre passengers to straddle.

However, the top of my head brushes the roof lining and the unusually high floor height (we assume caused by the underfloor battery) results in raised thigh angles that concentrate more weight on the lower back.

Given the rounded lower backrest cushions, which integrate with the ISOFIX child seat anchorages in the outer seating positions, also protrude into a passenger's lower back region, the rear seat provides less than ideal comfort for tall passengers in contrast to the sublime luxury up front.

Even so, rear passenger storage is well catered for with a bottle-holder in each door, pockets on both front seat backrests and two cupholders in the fold-down centre armrest. The rear of the centre console offers two more USB-C ports, adjustable air vents and adjustments for numerous comfort settings.

The power tailgate provides access to the fully carpeted rear luggage area, which offers up to 793 litres (almost 0.8 cubic metres) of load volume with the rear seats upright and up to 1722 litres (almost 1.8 cubic metres) with the seats power-folded flat. This provides a versatile space for carrying everything from a mountain bike to flatpack furniture.

The luggage area also has four tie-down hooks, a 12V socket and a hinged floor section which when opened reveals an underfloor bin ideal for storing charging cables (see image).

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 Lyriq features drive units with single-speed transmissions located at the front and rear which provide permanent all-wheel drive. Each is equipped with an electric motor, which combined produce 388kW of power and 610Nm of torque. There are also numerous selectable drive modes. Claimed 0-100km/h acceleration time is a rapid 5.3 seconds.

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.

GMANZ claims official combined consumption of 22.5kWh/100km and up to 530km of driving range from the Lyriq’s 102kW lithium-ion propulsion battery.

When we collected our test vehicle the dash display was showing 100 per cent charge and an estimated driving range of 583km.

We drove 239km over five days and still had 52 per cent charge and 300km of range remaining when we did an overnight charge at home using the supplied AC charger with a domestic three-pin plug.

However, after 15 hours the charge only increased from 52 to 65 per cent for just 76km of extra driving range, so we would recommend installing a dedicated wall box for faster home charging.

In total we covered 297km across our usual mix of suburban, city and highway driving with average energy consumption just under the Cadillac's official figure, so based on our test results a driving range of around 500km per charge is credible.

GMANZ claims 7.4kW AC charging can add up to 43km of range per hour, which increases to 94km with 22.1kW charging. And up to 128km of range can be added in just 10 minutes using 190kW DC fast charging.

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.

The driving position is supportive and comfortable with multiple power-adjustment of the seat and steering wheel ensuring people of most heights and girths can enjoy luxurious travel.

The low dashboard height ensures vision to the front of the bonnet and its array of physical buttons, knurled dials and knobs minimise touchscreen use, which makes driving far less distracting than having to search through digital menus.

It’s very quiet given its electric drivetrain. Most noise emanates from the tyres but that is also minimised by the audio system’s noise cancellation technology and the cabin’s effective acoustic insulation.

Ride quality and handling are excellent thanks to the Lyriq’s suspension refinement and close to an ideal 50-50 weight distribution mostly influenced by the positioning of its drive battery.

This battery’s considerable heft (we reckon it weighs at least half a tonne) also creates ample sprung weight to assist the suspension in smoothing out bumps and its underfloor location ensures a low centre of gravity for surefooted cornering.

Standing start acceleration is more than impressive for a luxury car weighing almost 2.7 tonnes, with instantaneous torque from its two electric motors helping to propel the Lyriq to a neck-straining 100km/h in about five seconds.

This spirited response creates a sporty and engaging drive that belies the vehicle’s weight, particularly in Sport mode with its sharper throttle response and firmer steering feel.

We also like the choices for regenerative braking which include ‘One Pedal Driving’ mode with 'Normal' and 'High' settings, both of which make the quartet of disc brakes largely redundant (the High setting feels like heavy pedal braking) while optimising battery charge. There’s also a small paddle on the steering wheel which increases regenerative braking in response to the amount of finger pressure applied to it.

Our only criticism from a driver’s point of view is the absence of a head-up display (HUD) and traffic sign recognition (TSR), both of which are notable omissions for a prestige vehicle in this price range.

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.

The Lyriq comes standard with a five-year/unlimited km warranty including five years' of roadside assist, while the propulsion battery is covered by a separate eight-year/160,000km warranty.

Scheduled servicing is every 12 months/12,000km whichever occurs first, with costs for the first five years of scheduled servicing or five scheduled services included in the vehicle’s purchase price. These servicing terms are generous for this segment, although some rivals offer similar enticements like Audi’s six-year ‘complimentary’ servicing for its Q8 e-tron.

GMANZ has a national network of 45-50 dealerships across most capital cities and some regional areas but not all offer vehicle servicing.

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.
