Lexus RC300 vs Lexus IS300H

What's the difference?

Still a rock-solid option in the (admittedly not massive) premium-coupe space, the Lexus RC looks and feels like a quality product. The 2018 update has addressed any safety shortcomings, even if the interior technology still feels a touch behind the times.

But an out-and-out performance car this ain't. Even in cars fitted with the big V8 engine, the RC behaves more like an effortless grand tourer than it does a performance coupe. But if we're being really honest with each other, that only serves to make it much easier to live with.

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.

Yes, yes - eye of the beholder and all that business. But for mine, the RC looks terrific. We cycled through two models, the RC350 and the performance-focused F Sport, and both cut a fine and athletic figure on the road.

Front on, the pincered grille dominates the view, sweeping back into bonnet, and stretching to the lowest corners of the front end, while a flared-lip body kit runs the length of the body. Special mention also goes to the cat-claw swipes that live behind the rear wheels.

The regular RC models make do with twin exhaust tips, while the F Sport range scores quad pipes, separated by a slinky rear diffuser, and the rear spoiler is an integrated lip that forms part of the boot. Cooler still, the Carbon Edition adds lightweight elements, like a carbon-fibre roof panel and an active rear wing - with about 6.6kg shaved off the kerb weight.

Climb inside, and you'll find a quality - if slightly dated interior - with soft leather seats, carbon-effect trim elements and a new, 10.3-inch screen in the centre of the dash.

As you can see from our interior photos, though, some elements do now feel a little behind the times. The door panels feel harder than I'd like, almost as if a thin-piece of leather has been stretched over hard plastic, and the control unit in the middle of the cabin is awash with hard black plastic, and the knobs mounted on it feel a touch cheap and non-premium, too.

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.

Now look, if you see a future filled with trips to Bunnings or ferrying the troops to soccer training, the RC is not for you. It's a two-door, four-seat coupe - and those two rear seats couldn't be less helpful for adult-sized humans if they'd been painted on.

Its dimensions measure 4695mm in length, 1840mm in width and 1395mm in height, but most of that space is focused on the front-seat riders, where your surrounds feel sporty-snug, but not claustrophobic.

Up front, that cursed mousepad control system is still in full flight, but the screen it controls is now bigger. There are two cupholders to be shared between front-seat folks, as well as the usual compliment of USB and 'aux' connections. And even a CD player, for that matter.

Climb into the back, which is no easy task in and of itself, and you'll find the space cramped for anyone but kids. But while it's tiny, it's clever. Deep cut-outs in the rear of the front seats mean more room for your legs. Headroom, however, is a problem, and my (I'm 176cm) head was touching the roof.

There are two cupholders, at least, but - surprisingly - little in the way of entertainment connections. You will find an ISOFIX attachment point in both of the rear seats.

The boot opens to reveal a fixed 423 litres of space, which is handy enough for weekends away. Predictably, though, extra practical accessories are fairly limited - you can forget optional roof racks.

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.

The more you spend, the more you get. Spring for the 300, and you'll find a 2.0-litre turbo engine nestled under the bonnet, good for 180kW at 5800rpm and 350Nm at 1650rpm. It pairs with an eight-speed automatic, and shuffles power to the rear wheels.

Step up to the 350-badged cars and your engine specs improve accordingly. You'll now find a 3.5-litre V6 motor providing the horsepower, good for 232kW at 6400rpm and 380Nm at 4800rpm. The gearbox (eight-speed auto) remains the same, and the power is still sent to the rear axle.

The pick of the power bunch, though, is the 5.0-litre V8 engine nestled in the RC F cars. It'll fire 351kW at 7100rpm and 530Nm at 4800rpm toward the rear wheels - more than enough to shift the 1820kg (tare) weight. It's paired with an eight-speed automatic, or what the Lexus spec sheet refers to as a "Sports Automatic".

There is no AWD or manual transmission option anywhere in the range, and for specific oil type etc, consult your owner's manual.

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.

Let's start from the top, shall we? There is a price to pay for power, and the V8-powered Lexus arrives with its claimed 10.9L/100km on the combined cycle. That's quite a lot, and it's a number that will surely only worsen if you drive the RC F the way that you really should drive it.

Things improve with the 3.5-litre capacity engine, recording 9.1L/100km on the same cycle, while the 2.0-litre engine will return 7.3L/100km.

There is no diesel engine anywhere in the range, and the fuel-tank capacity across the board is 66 litres, with 95RON fuel required.

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.

Having now spent a fair chunk of time behind the wheel of the V6 and V8-powered cars, we're ready to make a pretty bold claim: the six-cylinder engine is - and there's no other way to put it - simply more fun.

Shocking, I know, but there it is. There's effortless power on offer in the RC F models, of course, but it's the way that power is delivered that makes it feel like more of a loping grand tourer than a fire-breathing performance coupe.

For one, both the power and exhaust notes arrive in stages. So if you're gentle with the throttle - like you almost always are in the CBD or suburbs - it wafts around in near silence, the engine feeling anaesthetised, and like it's only using a tiny proportion of its available oomph.

The V6 engine just feels sportier. It's still not super emotional, but I think it reacts to inputs quicker.

Leave your foot buried, however, and the character transforms, the exhaust booming into life and that big V8 finally unlocking its prodigious power. With the adaptive dampers (no air suspension) set to the sportiest setting, it sits flat in corners, with nary a roll through the body. And while there isn't an intimate connection with the road below, nor masses of feedback through the steering, it does acquit itself well on the bends.

But... the V6 engine just feels sportier. It's still not super emotional, but I think it reacts to inputs quicker, and comes alive a little lower in the rev range than the big V8. It doesn't really matter if you're in Normal, Sport or Sport+, it just feels more vibrant. Hell, you can even get the traction light flashing if you're particularly silly with the accelerator.

And as such, it's our pick of the bunch. Sure, it can't match the outright performance of the V8, nor the speed of its 0-100km/h acceleration time, but it puts a bigger smile on your face in normal, day-to-day driving. And let's face it, that'll be 90 per cent of the time you spend behind the wheel.

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.

The RC range is covered by a four-year/100,000km warranty, with service intervals pegged at 12 months/15000km. There is no capped-price servicing program on offer, but Lexus will guarantee you a loan car every time your vehicle is in the shop, and will even come to your house or workplace to collect - and drop-off - your car.

For any owner-reported reliability problems, keep and eye on our Lexus ownership page.

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.
