Lexus GX vs Lexus RX500H

What's the difference?

Talk about nailing the brief. If you can live with the fuel bill, the Lexus GX won’t just drag you up from a Prado, but sideways from an LC300. I still think the Overtrail looks the best, but if yours is a city life, you can’t go past the entry-level model for its value proposition.

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.

I reckon Lexus has nailed the brief with this GX, especially in the deep 'Graphite Black' which makes it look even tougher.

It’s worth pointing out there are two distinct looks on offer with this Lexus, the Overtrail fitted with smaller wheels, off-road rubber, more aggressive arches and unique bumpers.

The Luxury and Sports Luxury are more street style, and I think the GX Overtrail looks ace. There’s no over-the-top grilles or design flourishes, just a big, blocky SUV that looks plenty tough.

Inside, it’s a high-tech and premium feeling space. The seats are lovely, the tech is big clear and easy to use, the cursed Lexus 'Remote Touch' track pad has been consigned to the history books in favour of a touchscreen and the lovely cabin materials extend to the back tows, too.

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.

The GX is a big truck, though admittedly not Lexus’ biggest , stretching just over 5.0m in length, a little more than 2.1m in width, around 1.9m in height and riding on a 2.85m wheelbase.

Only the Overtrail is a five-seater, with the more road-focused trims providing seating for seven. It also means the Overtrail gets more boot space, while the seven-seaters gets 291 litres of room behind the third row, growing to 1138 litres and 2177 litres when you start lowering the seats.

All models weigh in excess of 2.5 tonnes, by the way, and will tow a 3.5-tonne braked trailer. And for reasons known only to Lexus, there are 12 cupholders included, which means each passenger can bring 1.7 drinks.

The big question with seven-seaters is how much room you have in the back, and the GX is pretty generous. I enjoy plenty of room for my 175cm frame behind the driver’s seat, and climbing into the back is relatively easy, too.

The middle-row seats collapse and fold right away, meaning you can climb into the third row without too much grunting. And once there, you’ll find room for adults along with two of the five USB connection points dotted around the cabin.

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.  

This is a pretty straightforward choice, as you get to choose from exactly one engine option. Every GX scores a very punchy 3.5-litre, twin-turbo V6 engine, along with a 10-speed automatic that feeds the power to all four wheels.

The engine produces 260kW and 650Nm and it feels sprightly.

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.

It is thirsty, the GX. It has a big 80-litre fuel tank and the official fuel consumption figure for the combined (urban/extra-urban) cycle is 12.3L/100km.

That translates to a theoretical range of 650km. But I don’t love your chances. We were using more like 20 litres per hundred kays (though that was in the city) which drops the range figure to more like 400km.

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.

Piloting a big 4WD with genuine off-road aspirations in the city is always a lucky dip, but the Lexus GX falls on the more car-like side of that equation.

Sure, it never feels quite as tight as a true road-focused SUV, but nor does it feel overly floaty and hard to manoeuvre. In fact, should you never venture off the tarmac — which I suspect is a category many of its owners will fall into — you can pretty easily forget you’re driving a Prado-based 4WD.

The steering feels a little vague, and the manoeuvrability isn’t terrific, but the tech on board makes navigating tight spaces pretty breezy, and I found it easy enough to drive and park in town.

That engine, by the way, is a gem. Sure, you can feel your child’s trust fund evaporating every time you flatten the accelerator, but the GX doesn’t want for grunt, and you’ll have no problem getting going and up to speed.

The transmission is seamless in the way it goes about its business, and while not particularly quiet, the drivetrain feels like it perfectly suits the nature, and size, of the GX.

In short, it's an off-roader that won't sap your will to live should you never venture off the tarmac, and it looks damn good doing it, too.

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.

The GX is covered by Lexus' five-year/unlimited kilometre warranty, which is good. And there’s five years capped-price servicing, which is also good.

But less good is the fact service intervals are every six months, which is annoying, and they cost $595 a pop, which means you’re looking at almost $1200 a year to keep this on the road - or almost six grand over the first five years.

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.
