Lexus RC300 vs Rolls-Royce Cullinan

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.

The Cullinan might not be the most beautiful or traditional Rolls-Royce, and it’s a shame modern success means providing an SUV option to everyone, but it’s still a remarkable machine, either to drive or just to sit in. It remains not just a marvel of engineering, but a marvellous of engineering. Hats doffed, old bean.

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

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.

It is something of an achievement when a team of designers manage to make a facelifted version of a vehicle less ugly, daunting and disappointing than the original.

I thought the first Cullinan, launched five years ago, looked like a London black cab that had been mounted and inseminated by a double-decker bus. Big? Sure? Impressive? Yes. Beautiful? Only if you think Boris Johnson is sexy.

There was a lot of chat at the launch about the changes made for Series II, but in summary they tried to make it look more… like a boat, according to Exterior Design Lead Henry Clarke.

“We don’t look for speedy, overcomplicated lines, we take our inspiration from the luxury world, and it’s often from yachts, it’s that same sense of scale and grandeur, that’s the key to the timelessness of a Rolls-Royce,” he explained.

“We’re not focused on the world of automotive design, and if you look at the Cullinan it has that ethos you think of with a yacht, that strong, vital bow and then everything rearwards, the back of a yacht, has an elegance and grace to it.”

Fair enough, but what I appreciated was that they’ve squared the front end off a bit more, by outlining the grille, adding some gills beneath it and putting in some natty DRLs, and then rounded off the rear a little as well, so that it looks less… awful.

Indeed, after a couple of days of staring at it (and particularly admiring how good it looks in your rear-view mirror when behind you), I did come around to its looks. Certainly a lot more than last time.

And strangers driving past seemed to really like it, because they keep smiling and clapping at me. 

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.

In terms of being a vehicle you might actually use - and keeping in mind that if you can afford one of these you’ve also got at least a half dozen other choices - every day, the Cullinan is the pick of the Rolls-Royce enclosure.

From the big boot space - 600 litres with the seats up, 1930 litres with them down - and its lovely little Viewing Suite, through the spacious rear relaxing zone to the absurdly comfortable and plush front seats, there’s a sense of grandeur about the whole Cullinan experience.

You can opt for a champagne fridge between those rear seats, if you like, or you can just lie back and stare at the blinking pins of light in your 'Starlight Headliner' and imagine that each one of them represents one of your millions, smiling down at you.

It’s a lovely place to be, in short, and with its super-thick double glazed glass, coated with an acoustic layer on top of that, and carpets thick enough to keep out road noise on their own, it’s also a very pleasantly quiet one.

Value? Price? What are these things you speak of, little plebeian person? Such is the disdain for such things at Rolls-Royce that they wouldn’t even tell us what the Series II is going to cost when it lands in Australia later this year. 

The people who can afford one don’t much care, of course, but for the rest of us, who like to shake our heads and make low, whistling noises, you can bet the price will rise just a little from where it was with the original Cullinan - and that was $705,000 for the basic car, or closer to $795,000 for the sportier, and blacker, Black Badge variant.

In terms of value, it’s hard to grasp that any car could cost that much, but for a Rolls buyer the equation is very different. They don’t need a Rolls, no-one does, but it makes a nice change from buying art works, gold or small countries. 

In terms of features, it has almost too many to mention, but let’s pause on the marvellous massage seats, the bespoke sound system, entirely unique to this case and built by Rolls itself, with incredible levels of detail, the Rolls umbrellas tucked into each door and the very lovely 'Viewing Suite'.

This consists of two pop-up seats in the rear, with a little champagne and canapés table in between, where “you can watch your children play football”.

Try that in Australia, at the rugby league, and you’ll be covered in half-time oranges and abuse spittle in no time. Stick to the polo, perhaps.

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.

Rolls-Royce has committed to being a fully EV brand by 2030, so it’s a safe bet this Series II Cullinan will be the last one offered with its storming, staunch V12 engine. 

Indeed, Rolls hinted the only reason it hung around in this version is that this is only a mid-life face-lift for the Cullinan, and the car that replaces it will arrive on an entirely new, all-electric platform.

As good as the EV Roller, the Spectre undeniably is, driving this old-school Cullinan with its 6.75-litre twin-turbocharged V12 making the kind of thumping, torque-thick, nothing-is-too-much-trouble acceleration is a hoot.

It’s not loud, but it’s just loud enough that you can enjoy its deep, brassy tones, and it’s got plenty of power in reserve to hurl even this 2.75-tonne machine past lesser vehicles with ease.

There are two Cullinans to choose from, of course, with the base model providing a very pleasant 420kW and 850Nm or the sportier Black Badge version (Rolls calls it the brand’s “alter ego”) with 441kW and 900Nm. 

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.

Rolls-Royce claims the Cullinan will provide you with between 16 litres per 100km and 16.8L/100km, but I believe you’d have to drive it quite steadily to achieve even that quite appalling figure.

Twelve cylinders, 2.75 tonnes, you do the math, but it's interesting to note that with a nearly full tank - and we’re talking 100 litres of fuel - my distance to empty was looking like barely more than 500km - that’s an EV-like number.

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.

The first word that comes to mind when describing the experience of driving a Rolls-Royce the size of a small housing estate is 'intimidating', because it's one of those cars where you take a few deep breaths before setting off (while muttering “please don’t crash it”) and then some sharp intakes of breath the first few times you find cars coming towards you on a narrow road, of which there are many on Ibiza where we were summoned to drive it.

I followed a panicked young man from India who had never driven a Rolls, nor a left-hand-drive car before, and boy, he sure looked intimidated, even if he didn’t ever get above 30km/h.

The incredible thing about the Cullinan, however, is how quickly it relaxes you and how astonishingly light and easy it is to drive. The steering feels almost absurdly light at first, you really can drive it with just one finger, two if you’re feeling cautious, but once you get used to it it just feels very Rolls-Royce.

The whole brand lives on the idea of effortlessness, wafting over the world, and the much-touted 'Magic Carpet Ride', and it really does deliver that sense of ease. You’re almost as relaxed at the wheel as you are in the rear seat (and the massage functions only make you feel more so). 

Speed humps do upset the Cullinan, but only a very little, and you’re aware when the car finds broken surfaces, but only distantly so. It feels like someone is dealing with bumps and imperfections in a far-off-place, perhaps the car’s basement, and it shouldn’t worry you too much.

When traffic annoys you, you can just make it disappear by engaging your whumping V12 engine and making the world go briefly blurry. 

Attempt to throw the Cullinan through sharp bends at speed, however, and it reacts in much the same way you’d expect the cruise ship it somewhat resembles to.

There’s a bit of body roll, but it’s all quite polite and a sense that if you need to drive like that, perhaps you should go and get one of your other cars.

The Black Badge version does feel just a trifle sportier than the base Cullinan but we’re splitting very grey and expensively coiffed hairs here.

The overall experience is one of grand relaxation, imperiousness and a certain touch of superior glee.

The Rolls-Royce Cullinan SUV has not been ANCAP tested, but it feels safe because it’s bigger than a tank. It has eight airbags - driver, front passenger, two curtains, driver side, front passenger side, two rear passenger side), and a full-suite of active-safety tech including Forward Collision Warning and Automatic Emergency Braking. 

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.

Questions about service intervals and warranties seem to confuse the people at Rolls, as if none of their customers have ever bothered to ask.

Yes, you would think servicing would be free when you’re pushing a $1 million price tag, and that the warranty would be for life, particularly considering the low mileage on these things, but it is, in fact, just a four-year servicing and warranty offer for Australian customers of this vehicle. So that means an unlimited-mileage warranty, including all services, for the first four years (at which point you obviously buy a new one). "Rolls-Royce Motor Cars will offer a service inclusive package but no pricing available yet and this will not be required until the fifth year of ownership."
