Lexus LC500 vs Lexus RX500H

What's the difference?

Stunning to behold, and even more so to listen to, the LC 500 Convertible with no doubt turn as many heads as its owners surely want it to. It's not the final word in performance, but it's a lavishly equipped transporter none the less.

The Lexus RX500h F Sport Performance certainly gave a solid driving performance this week. I was comfortable behind the wheel and enjoyed the luxe features up front. I feel that it's missing some luxe items in the back seat and some of the family storage options that other large SUVs can have but otherwise, it suited my family’s needs. The fuel efficiency was quite surprising for a hybrid, so this gets a 7.0/10 from me.

My son really liked the panoramic roof and his high seating position. So, he gives this an 8.0/10.

It’s eye-catching, the LC 500, if big, bolshy convertibles are your thing, and especially viewed front-on, where the aggressive nose design ends in a sharp crease in the mesh grille. I love the headlight design, too, which bleeds back into the body work, but also merges with the vertical light cluster that bookends the grille. 

The side view is all shining alloys and sharp body creases, too, leading to an oversized boot that stores the fabric, aluminium and magnesium roof structure, which drops or raises in 15 seconds at speeds of up to 50km/h. The design fits into what Lexus calls an “impossibly small space behind the seats”.

Inside, it’s a snug but luxurious space, wrapped largely in leather and equipped with a wealth of technology. It’s a point we’ve made before, but why Lexus perseveres with its trackpad infotainment control technology is beyond us, but there’s no denying the cabin of the LC 500 is a wondrous place to spend time. 

We particularly like the integration of the centre screen, which is recessed beneath the leather-wrapped edge of the dash. While some look like an afterthought, this appears to have been included in the broader design philosophy.

The RX is a deceptively large SUV, at first glance the sporty tailoring might make you think it’s the smaller NX sibling but park it and you’ll see how it fills up a space!

It’s 4890mm long and 1920mm wide but the compact 1695mm height is what causes the misdirection.

Let’s get straight into some of the obvious design changes. The iconic ‘spindle’ grille design has been flattened at the top with a new body panel. It’s a design choice that makes the bonnet look more bulbous than sporty but that’s pretty much all I don’t like.  

It was a great choice to lift and level out the sloping of the bonnet because it looks a lot more purposeful now. There’s lots of sporty elements too with the black 21-inch alloy wheels and faux-mesh intake vents at the front and rear. Plus, I’ve always been a fan of the floating roof effect that’s created by the black panelling that shoots from the C-pillar to the rear.

It’s not just the exterior that’s been revamped. The interior now boasts a massive 14-inch touchscreen multimedia system, up from the 12.3-inch screen from the previous generation. The gear shifter is now an e-shifter and the dashboard has been ‘stepped’ to make it feel like you’re being tucked into the cockpit. There’s new ambient lighting inside too, designed to make the interior feel like a luxury lounge.

All round, they’ve nailed the ‘luxury’ aspect.

It’s not, really. But then, what were you expecting?

As mentioned above, the interior feels snug for upfront riders, but not in a bad way. More that elements of the interior feel like they’re reaching out to greet you, leaving you with the impression of being tucked into the cabin.

Backseat riders are out of luck, though, with the seats really only reserved for emergencies. Legroom is tight, and while Lexus promises the roofline is about on-par with the Coupe, it’s not going to be a comfortable journey.

The LC 500 Convertible stretches 4770mm in length, 1920mm in width and 1350mm in height, and it rides on a 2870mm wheelbase. It will sit four at a pinch, and provide 149 litres of luggage space.

There are two ISOFIX attachment points in each of the rear seats, as well as top-tether points.

Sometimes you can forget how many luxury items this car has because they've been sprinkled around too sparsely.

For example, front passengers definitely enjoy the most this car has to offer. The legroom and headroom are both great, while the luxe factors feature heavily with the heated and ventilated seats and heated steering wheel. It’s great that there is dual-climate control up front and ample individual storage on offer.

The driver has a lot of technology within easy reach – the 14-inch touchscreen multimedia system is simple to use and has built-in satellite navigation. You can pull the directions into the head-up display and there’s still a healthy mix of physical dials on display. The wireless Apple CarPlay was easy to connect to and there’s also wired Android Auto, Bluetooth connectivity and digital radio (which was good in the city, terrible in regional areas).

Front passengers are absolutely spoiled when it comes to charging options, too. You can choose between an USB-A port, three USB-C ports, 12-volt port and a wireless charging pad!

When I reviewed the smaller NX sibling, I struggled with the e-latch door handles but finally got used to them on this model (I even like them!). My six-year-old found them to be frustrating at times and if the groans from my family members are to be believed, they weren’t impressed either but I do think it came down to it being a ‘user’ issue!

The backseat is comfortable and perfect for my 168cm height but taller passengers may feel a little cosier. The seats are set in a stadium setting, which does make you feel like you’re teetering in corners but my son loved the high position.

You can comfortably fit a couple of child seats back there but it might be a squeeze for three. The wide door apertures do make it easy to fit a child seat and to bend down to buckle them in.

Individual storage is limited to just map pockets, two cupholders and skinny drink bottle holders in the doors. The amenities never quite make it to luxurious either but I did like seeing two USB-C ports and retractable sun blinds.

The boot space is decently sized at 612L but the aperture is sloped, which means you might struggle to fit some bulky items. It has a level load space and it’s easy to access the temporary spare tyre. The powered tailgate with kick-function is super quick and handy too. 

There are six models for the RX and the 500h Sport Performance completely replaces the previous 450h model as ‘top dog’.

As with most things, the purchase price has shifted upwards with a hearty $126,000 tag (before on-road costs). However, it’s still almost $10K more affordable than its nearest rival, with the X5 at $139,900 and the GLE at $135,200 (all before on-road costs).

Being a top model means you enjoy the perks of many features coming as standard, like electric front seats with lumbar support, heated and ventilated front seats, heated steering wheel, panoramic sunroof and leather accented seats and trim.

It even has real aluminium inserts for the accents and a new for 2023 digital rear-view mirror.

The only luxe factor that it doesn’t have, but should for a flagship model, are heated and ventilated outboard seats in the back row.

Other features include some decent tech, like wireless Apple CarPlay and wired Android Auto, three-zone climate control and a premium Mark Levinson sound system but more on that below.  

It’s a lusty power plant, this one, and not something you immediately expect to find in a luxurious Lexus convertible.

The 5.0-litre V8 produces 351kW and 540Nm - 260kW of which arrives from 2000rpm - and it sounds like a God of Thunder as it’s doing it. 

It pairs with a 10-speed automatic and sends all that grunt to the rear tyres, with Lexus’ Active Cornering Assist and a mechanical limited-slip differential helping you to not make a mess of things when tackling corners. 

There is only one engine for the top model and that’s a 2.4-litre, four-cylinder turbo-petrol hybrid offering. It has a combined max power output of 273kW.

This replaces the old V6 hybrid engine from previous models but I found it to still be punchy. In fact, it’s claimed that you can do 0-100km/h in as little as 6.2 seconds.

It’s an all-wheel-drive and features a cool – eAxle … meaning the car is a bit clever with its power distribution using the electric motor to power the rear axle and the petrol engine to power the front. You can notice the gear changes with the six-speed auto transmission but overall, this combination delivers a solid performance.

Remember when I said it was lusty V8? When has that ever been good news for fuel use?

Lexus reckons you’ll get 12.7L/100km on the combined cycle, but the temptation of all that grunt will pretty much ensure that never happens. Emissions are pegged at 290g/km of C02.

The LC 500 Convertible’s 82-litre fuel tank only accepts 98RON fuel.

The official combined fuel figure is 6.5L/100km and that’s up by half a litre on the previous model. Real-world testing saw my figure at 8.3L, and I was disappointed with the efficiency. There are more efficient options out there that I would consider if the ‘hybrid’ part of the model’s name was what interested you.

With the 65L fuel tank and based off the official combined figure, you should be able to get a 1000km driving range … but based off my experience, I would expect a little less than that.

It’s a tough nut to immediately crack, the LC 500 Convertible.

It feels like it really wants to be a super-accomplished performance car, and on longer, more sweeping bends it is, with that thick flow of power ensuring you simply surf through corners before rocketing out the other side, the air filled with that growling exhaust note as your right foot finds its way to the carpet.

But on the tighter stuff, there are some factors that play against it. The suspension feels sorted and that engine is always willing to deliver, but for mine, the steering and brakes felt a little disconnected from the experience, not inspiring much in the way of late-braking confidence. And then there’s the sheer two-tonne-plus weight of the thing, which can’t be totally hidden, even by Lexus’ best wizardry.

Don’t get me wrong, it’s very capable, even on surprisingly tight stuff. It’s just that there’s something of a disconnect between car and driver. 

That’s not a bad thing, really. Are you really buying a premium convertible to attack a mountain pass? Probably not. And keep it flowing through corners and the LC 500 Convertible will keep a smile painted on your face, owing mostly to wave of torque you can ride to your destination. 

Hovering your foot over the accelerator must surely be what the President feels like whenever he stands near the nuclear football, with that big V8 always ready to turn on the fireworks. 

Away from the red mist, you’ll find the LC 500 Convertible positively flows from destination to destination, the 10-speed gearbox - which can feel flustered at pace - seamlessly flicking through its options, and the ride in its most comfortable settings disposing of most road imperfections before they enter the cabin. 

The cabin is also very cleverly insulated, not just when the four-part roof is up, but also when it’s down, with the climate and ambience of the interior largely unaffected by what’s going on in the outside world.

My first thought when I drove this was that it doesn’t drive like a big car. It has nice sporty handling – it feels firmly positioned on the road and the steering is responsive.

There’s a definite sense of power but it’s lazy. You have to get firm with the accelerator but it performs well when you push it.

There’s an interesting duality at play here because, despite this, it’s not sluggish - I’m just as confident on the open-road as I am zipping across traffic in this.

The suspension is adaptive and feels springy. It handles cornering quite well but I’m not as firmly seated as I would like. My husband said the same from the passenger side.

The cabin is extremely quiet and peaceful until my kid gets into the car. Then it’s 20-questions in 20-seconds. But otherwise, the new active noise cancelling this model has, works.

I really love the 11m turning circle – parking this in a rat-warren car park was simple. The 360-degree view camera is easily in my top three for camera tech that I’ve used and I like how the car ‘disappears’ when you’re manoeuvring. It makes it easier to navigate a tight spot and not get distracted. Large SUVs can sometimes feel daunting to park but not this one.

The RX has a full suite of safety features that are always great to see on a large SUV, like: LED daytime running lights, lane keeping aid, lane departure alert, blind spot monitoring, rear cross-traffic alert, 360-degree view camera, front and rear parking sensors and dynamic parking guidance.

A cool highlight is the 'Safe Exit Assist' which will alert you via the dash if the car has sensed an oncoming obstacle when you go to exit the car. However, Lexus goes further and if the obstacle is still present and you try to open the door, the car will LOCK your door and stop you from exiting. Pretty neat!

The autonomous emergency braking with forward collision warning has car, pedestrian and cyclist detection (operational from 5.0 – 80km/h and up to 180km/h for car detection).

It achieved a maximum five-star ANCAP safety rating from testing done in 2022. However, this model used to have 10 airbags but now only has eight. I do like that it now has the front centre airbag.

There are ISOFIX child seat mounts on the outboard seats and three top-tether anchor points. You may get lucky with three skinny child seats but two will fit best. A 0-4 rearward facing child seat can be installed but will encroach on front passenger comfort, especially if they’re tall.

Lexus vehicles are covered by a four-year, 100,000 kilometre warranty, and the LC 500 Convertible requires servicing every 15,000kms. 

Lexus's Encore ownership program includes pick-up and drop-off servicing, but the new Encore Platinum level for owners of its more exclusive models unlocks even more stuff.

One is a new On Demand service, which allows owners to book a different style of car when heading off on a holiday or business trip. The loans are available in your state or somewhere else in Australia if you're travelling, with your car waiting for you at Qantas Valet for you when you arrive.

The On Demand service is available on four occasions over your first three years of ownership (which is also the length of the Encore Platinum membership). 

The ownership terms have been improved too with the RX now coming with a five-year/unlimited km warranty term, which is more in line with the market standard.

It has a five-year/75,000km capped-price servicing plan and services cost $695, which is $100 more than the previous model. Even with the price hike, the servicing costs aren’t as expensive as others in the class. 

Servicing intervals are reasonable at every 12 months or 15,000km – whichever occurs first, which is good.

Lexus recommends a minimum of 95 RON petrol for this model.
