Lexus GS vs Lexus IS

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.

Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.

While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.

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.

Look closely and quite a lot has changed. This is really a story of doing a facelift right. Lexus has kept all the great-looking bits of the car that launched in 2013, like its striking side profile and angular accents, while dumping most of its least popular elements like the spidery front light-clusters and busy front splitter, in favour of something more refined and conservative.

It even adds some new flair in the rear three-quarter, with dramatic LED light-clusters working their way into a trendy highlight strip across the boot lid.

These changes all add up for a much tougher, sportier, and nuanced design compared to the outgoing car. One that manages to make an eight-year old design look as contemporary as ever.

I even liked our test car in its plain black shade, although I'm less sure about those conservative-to-a-fault, almost Camry-esque alloy wheels.

On the inside, sadly not a whole lot has changed. The busy design looked dated when this generation of IS launched in 2013, and it still looks dated now.

The visual assault of buttons, toggles, displays, textures, and trims is a lot to take in, and makes the cabin feel smaller than it is.

It probably didn’t help the sensory overload of this car’s interior as I hopped out of the stripped-back interior in the Tesla Model 3 I had the week before.

My less-than-impressed brother, a student of design, described the IS’s interior best when he told me “It’s a bit maximalist, don’t you think?”

If nothing else, at least Lexus hasn’t blatantly imitated anyone else when it comes to its interior, but the brand remains firm on dorky design items like the laptop touchpad, redundant drive-select dial, and odd vacant panels under the climate unit which do it no favours.

A welcome upgrade for the 2021 model year is the new media screen, a highlight piece perched atop the dash. It’s bright, has excellent contrast, and doesn’t seem to fall victim to glare.

The Apple CarPlay support I used was seamless and sharp and made the most of the available real-estate in its widescreen layout.

I somehow didn’t mind that the instrument cluster in this base car is analog. It almost suits the IS’s character better than a digital set-up would. Also offered is a small information display between the dials which I used for monitoring the hybrid drive.

A final note on the IS’s design. The fit and finish is quality, inside and out. It leaves you with an impression that this is an immaculately built vehicle, one that should be a must for all luxury cars, and always a strong point for Lexus.

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.

Well, the IS is a sedan, so it doesn’t quite have that high-riding appeal of an SUV, and for this update it has even leaned further into its low-slung proportions with a roofline that descends a further 15mm and a boot lid which is 31mm lower overall.

As with the previous car, the interior is quite closed-in thanks to that busy dash design and large centre console. Rather than feeling claustrophobic though, it is best described as cosy, with lots of plush finishes throughout the doors and centre stack befitting a luxury nameplate.

Adjustability is great for the front two occupants and there are two large bottle holders between the seats, a large but shallow console box under the armrest, bottle holders with adjoining bins in the doors, and a smallish glove box.

That’s about where storage ends though, with no extra trays or bins in front of the oddly placed shifter, just an awkwardly finished plastic panel where it feels like a little tray or storage cutaway should be.

The touchpad for operating the media screen joins an unnecessary drive-select cluster in eating up centre console space where there could be more storage.

The rear seat is quite limited on space despite being lavishly trimmed. I fit behind my own (182cm/6'0") driving position with little knee or headroom to spare.

Again, it’s cosy and very comfortable, but if you're taller or wider than me you may run into issues.

The centre rear seat is all but useless for adults, with the IS’s rear-drive architecture necessitating a huge transmission tunnel that almost comes as high as the seat base itself.

Storage is limited to pockets on the back of the front seats, small bins in the doors that double as handholds, and a drop-down armrest with two bottle holders.

There are no power outlets for rear passengers, but there are dual adjustable air vents.

Boot space is 450L which is a little small for the class. It’s impressive the hybrid only managed to lose 30 litres compared to petrol-only IS variants, though, so best to count your blessings.

The largest CarsGuide travel case easily fit in the wide but short available space.

To be precise the variant we’re looking at here is the IS 300h Luxury. It’s the base IS trim with the hybrid powertrain and it wears a before on-road costs (MSRP) of $64,500.

Base car or not, the new IS is very well specified. Now standard are 18-inch alloys (up from 17s), full LED headlight clusters, eight-way power adjustable front seats, dual-zone climate control, 10-speaker audio system, and importantly a brilliant new 10.3-inch multimedia screen with widescreen Apple CarPlay, Android Auto, built-in navigation, and DAB+ digital radio support.

Keyless entry and push-start ignition also continue to be offered, as well as a leather-look interior trim which in our car was in a rather contrasting 'Ochre' colour option.

Our IS 300h was also fitted with the creatively named ‘Enhancement Pack 1’ which adds an openable moonroof for $2000. The significantly more expensive ‘Enhancement Pack 2’ ($5500) adds the moonroof alongside 19-inch alloys, upgraded LED headlights, interior ornamentation, scuff plates, a panoramic reversing camera, 17-speaker premium audio, ‘leather-accented’ interior trim, ventilated front seats, and an electric rear sunshade.

These packs are seemingly largely unnecessary but are also very cheap for a brand at the premium end of the market.

Lexus has made pretty much all of its high-end active safety equipment standard on this base ‘Luxury’ for 2021, alongside some previously unavailable tech which we’ll take a look at in the safety section of this review.

At this price the Lexus IS 300h goes into battle against the Mercedes-Benz C 200 ($66,900), BMW 320i ($70,900), Audi A4 35 TFSI ($55,900), and the ever-looming threat of Hyundai’s Genesis, which offers its similarly-sized G70 in base form at $59,300.

Some of these base-spec rivals are cheaper, some are more expensive, but did you notice none of them are hybrids?

Access to Toyota’s affordable and popular hybrid drive is a real point of difference for the Lexus brand, and we expect it’s a key drawcard for the loyal customer base. More on that later.

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 IS 300h does stand out from the luxury sedan crowd by offering a hybrid drivetrain at a reasonable price. Some rivals offer plug-in options further up the price scale cementing them as a niche option, but the beauty of this Lexus is its very mild $3000 price jump over the base petrol car.

The base car’s 2.0-litre turbo is dumped in favour of a 2.5-litre non-turbo Atkinson-cycle four-cylinder hybrid set-up similar to the one proving popular in the Toyota Camry and RAV4.

The petrol engine produces 133kW/221Nm on its own, and the electric motor produces 105kW/300Nm. Toyota says the “combined system output” of this is 164kW.

Either way, that's less than the base 2.0 turbo. The 300h also swaps out an eight-speed torque converter automatic in favour of a continuously variable transmission. Rare in a rear-wheel drive car.

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.

As you might hope this hybrid IS has an astoundingly low official/combined fuel consumption rating of 5.1L/100km.

I was pleased to find that after a week of mainly urban driving conditions, our IS was returning a figure of 6.9L/100km. Not bad at all, especially for a class where fuel consumption can get a little out of hand with turbocharged engines or V6s.

Of course, using the hybrid system to your advantage over the long term will get this number much lower, as I discovered on my long-term test of the Toyota Corolla hybrid which essentially uses a smaller version of the same system.

Certainly, if fuel consumption is a high concern, you’re better off with this car than the top-spec V6 (IS 350) which will easily see consumption enter double digits.

Lexus recommends a minimum RON rating of 95 for the IS 300h, and the fuel tank is 66 litres regardless of variant, giving the hybrid an impressive theoretical range of around 1000km.

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. 

There is no doubt the IS 300h is capable. You can feel it through the car’s solid rear-drive underpinnings, silky smooth steering, and reactive chassis.

What this car doesn’t offer is excitement in quite the same sense as many of its rivals. That’s down to this hybrid’s drivetrain. It just doesn’t have that powerful follow-through in the same way turbocharged BMWs or Audis or Mercedes do.

If it’s that 'sports luxury' experience you’re seeking better off looking to the base 2.0-litre turbo or the V6 and their eight-speed automatics.

The 300h does offer something a bit different. The gentle refined efficiency of Toyota’s signature hybrid system in a luxury rear-drive package that’s smaller than this car’s ES bigger brother.

While it may feel capable thanks to the lighter suspension components and altered track that the brand has committed to for this update, the hybrid drive matches this car’s softer character brought about by its gentle suspension tune and light steering.

This is an easy car to drive around a city, it filters out bumps nicely, while offering near silence in the cabin and breezy steering for every day scenarios like manoeuvring in tight parking lots.

The CVT auto and instantaneous torque available from the electric motor make it best at traffic speeds, being both reactive and predictable, with silent acceleration when inching forward at the lights or cruising along at 50km/h.

As you might expect though, the wheezy Atkinson cycle engine and CVT conspire for a noisy and less than engaging experience under heavy acceleration.

It’s not as though you’re rewarded with particular vigour either, with this combination being a bit sluggish when a lot is asked of it.

It loses its reactivity and refinement at higher speeds or in the corners on country roads as the transmission elastically tries to keep up with the demands of the driver.

Still, few luxury sedans are quite as purpose-built for the toils of a city, and if you want to get drawn into this car’s hybrid drive antics, it’s easy to make a game out of saving fuel by trying to rely on its low-speed electric motor capability.

Really then, it leans into its urban luxury appeal. A luxury sedan for the streets of Tokyo. An ideal car in this class for the urban environment.

If you don’t care for the thrill of a turbocharger or frequently seek to explore the twists of your nearest B-road, you could do worse than the comfort and ambiance the 300h offers.

A full active safety suite is now standard across the IS range, including freeway-speed auto emergency braking with pedestrian detection (works during the day and at night) and cyclist detection (works during the day only), and a new intersection braking feature, lane keep assist with lane departure warning, blind spot monitoring, rear cross traffic alert with reverse auto braking, traffic sign recognition, adaptive cruise control, and auto high-beam assist.

There is also an auto SOS function, as recently added to the Toyota Yaris Cross, which automatically triggers if an airbag is deployed. On the topic of airbags, every IS has a thorough suite of 10 (dual front, dual side, quad head, dual front knee).

This all adds up with the standard array of stability, brake, and traction controls for a maximum five-star ANCAP safety rating, although the IS was last assessed way back in 2016.

The IS is built in Japan.

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. 

Lexus gets slightly ahead of the luxury pack with an extra year of warranty. While BMW and Audi still sit on three, Lexus offers four, but it is limited to 100,000km and is still outdone by Mercedes-Benz and Korean newcomer, Genesis, offering five-year/unlimited kilometre promises.

The IS has capped price servicing fixed at $495 for the first three years of ownership with roadside assist, and the brand will even pick up and drop off your car, or offer a free loan car during every 12 month or 15,000km service.

It’s worth noting that German rivals offer pre-paid service packages out to five years, and Genesis is trying to make a splash with free servicing.

Lexus does offer a luxury ownership program dubbed ‘Encore’ which includes invites to experiences and certain partnerships with restaurants and the like to keep potential owners enticed.
