Lexus GS350 vs Lexus LX450D

What's the difference?

Weirdly, given all the good things I've had to say about the GS F Sport, it doesn't quite hang together. It's missing that certain something the Europeans have in their chassis, particularly the BMW 5 Series, and with ageing interior tech, it's struggling to keep up.

It's a car built for specific tastes, and they're more California than Straya. And that's perfectly okay, but unfortunately, that doesn't translate to a stampede of buyers. Having said that, none of its German rivals (or its beleaguered Japanese counterpart, Infiniti) could claim wild sales success either.

The GS is a terrific car, underrated but also just not quite there for my taste. The GS F, though, that's another thing altogether.

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 GS is ageing well, but it's still a bit heavy-handed around the headlights and a little on the slabby side along the flanks. It doesn't look poised for action, even with the F Sport additions, but nor does it look frumpy, mostly due to the whopping blacked-out spindle grille, a Lexus signature. 

The rear end is good looking but a bit bluff, again neither surprising or delighting.

Little has changed inside, but it's still a very nice cabin, and always will be apart from a couple of clangers (the gear shifter looks super-cheap). 

What's more, it's welcoming, lots of very nice materials, comfortable, seats - it's exactly what it needs to be. Whatever you might think of the looks, one thing is absolutely certain - if anyone builds cars better than Lexus, it's a very, very short list.

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.

Being a big car, there's plenty of room inside. Four passengers will be very comfortable although rear legroom was a bit on the skinny side given the car's size.

The cabin contains a good-sized console bin, four cupholders and each door pocket into which you could conceivably slot a bottle.

The 520-litre boot is a useful shape, with a sensible load height and a space-saver spare under the floor. The 5 Series and E Class both best the Lexus by 10 litres, so the GS isn't far off the norm.

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.

Price as tested on our five-seat LX 450d is $136,000. The base RRP is $134,500 and our Lexus had premium paint (Sonic Quartz), which adds $1500; no other options were fitted. 

It is absolutely packed to the rafters with high-quality stuff, which is no surprise really because, at this price, you’d expect nothing less. Standard features include a 12.3-inch high-definition screen with nine-speaker, seven-channel audio system (with “digital sound processing”), satellite navigation, and four-zone climate control air-conditioning with climate concierge function and nanoe technology (claimed to purify the air and moisturise hair and skin, according to Lexus). It also has heated front seats, leather-accented trim, a wireless phone charger, cool box, rear-door sunshades, 20-inch alloy wheels with 285/50R tyres, tyre-pressure warning, LED headlamps, daytime running lamps and sequential turn signals.

There are seven exterior colours and two leather-accented interiors from which to choose.

The LX 450d does not have any enhancement packs.

Lexus fits a 3.5-litre (2GR-FKS) naturally-aspirated V6, delivering 232kW/380Nm to help shift the 1745kg GS. Power goes to the rear wheels via an eight-speed automatic. Lexus claims the sprint from 0-100km/h is completed in just six seconds.

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. 

A real world 13.7L/100km is a solid miss of the claimed 9.3L/100km, which itself is hardly earth-shattering. It's a big heavy car and that's the penalty. It drinks fuel fast, so the 66-litre fuel tank does drain quickly and it's worth knowing you have to fill it with the 95 RON or better.

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.

There are things you expect in a Lexus. Quietness. Composure. Smoothness. The GS delivers all three of those things effortlessly. But it has a few extra things in its bag that I can't say I was expecting.

For a start, the 3.5-litre V6 moves the car without any carry-on and in doing so, I was constantly amazed at how quickly the speed in the head-up display reached the posted limit. It just doesn't feel or sound like a six second car, but there you are. The transmission is virtually faultless, the engine sound distant and refined, the power impressive.

It's a heavy car, no question, but two things work to make it feel much lighter. First - and it doesn't matter which mode you choose - the adaptive suspension somehow knocks about 200kg out of how heavy the car feels. The brakes, while a little soft on pedal feel when you first step on them, are very effective and again help to make the car feel lighter than it is.

The four driving modes are quite distinct. As usual, Eco makes everything soft and doughy or as I prefer to say, unpleasant. Normal is great for every day, with just the right throttle response and steering weight.

Moving to sport ups the aggro slightly while Sport+, while never harsh, firms everything up to the point where it starts to feel like a different car. Sport+ makes the car feel race-car pointy, the suspension holds the body in check and the power seems readily available without jerky progression

The all-wheel steer is a big part of the change in feel. It's is especially sharp in Sport+ mode. The steering's gearing changes up quite a bit, meaning a lot less steering lock required for your favourite hairpin bend. Of course, at real speed it all calms down because neither you nor Lexus are fond of sneezy lane-changes or Armco-swiping. At first I thought it just made the big car feel a bit too nervous but as I got used to it (and was able to dial it down by switching back into a less racy mode) I found it fun but a little bit out of character with the car itself.

And just because it's the F Sport, that doesn't mean it can't do all the things you'd expect from a Lexus. You can still waft, you can still creep up on people and it's really very comfortable when you're cruising or stuck in traffic. 

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.

The LX 450d has a five-star ANCAP rating. It has the latest-generation Lexus pre-collision safety system with pedestrian detection, and 10 airbags. Other standard safety gear includes radar active cruise control, lane-departure warning, adaptive high-beam system, blind-spot monitor and rear cross-traffic alert, as well as clearance and back sonar, and reversing monitor with 360-degree view. 

There's one area where Lexus smashes the Germans and that's after-sales. While the warranty is hardly ground-breaking at four years/100,000km and service intervals are reasonable at 12 months/15,000km, it's how it all comes together.

For the duration of the warranty, when the car needs a service, Lexus will either come and get it then return it to you, or give you a loan car. Anecdotal evidence suggests this continues long after the warranty runs out. Like, 10 years after the warranty runs out. 

This is a small thing, but if there's one thing I hate about car ownership, it's the servicing experience. If I was a betting man, I'd dare you to find someone who genuinely has a problem with Lexus after-sales care.

On top of that, you get a generous roadside assist package for four years. 

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.
