Lexus LM 500H vs Lexus GX

What's the difference?

The Lexus LM 500h is luxurious, comfortable, practical, easy to drive and expensive. While it may appear to be the ultimate family car, with only four seats it's limited in terms of how many kids and their friends you can carry. On top of that, the privacy screen introduces accessibility issues to the kids you wouldn't encounter on other vehicles. If you are thinking of a Lexus people mover as your next family car I'd suggest looking at the LM 350h which has seven seats and no privacy screen. If you’re looking at a business class executive van the LM 500h would be perfect. 

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 LM 500h doesn't look real. More like a concept vehicle with its vertical face wearing that enormous grille. Feels like if you watched it for long enough you’d catch it transforming into some kind of robot. Yet, at the same time its styling is elegant and prestigious.

I have a confession to make. I used this Lexus as my office. Its interior is that comfortable and spacious. I'm also a parent and there were times where it was the quietest place to get some work done.

It also let me observe people's reactions as they walked past with their dogs not knowing what was going on inside behind those tinted windows. The people that noticed were clearly car enthusiasts as they knew what they were looking at and couldn't pass without gaping it awe.

The LM 500h’s interior is superbly plush with thick carpets, beautiful copper metallic trim and nappa leather seats.

As I’ve said, the cockpit up front is less luxurious than the extravagant first class section in the back behind that dividing wall.

And yes, I’ve seen large screens before but nothing that stretches the width of the vehicle.

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.

You might be able to take Lexus out of Toyota but it's very hard to take Toyota out of Lexus and this particularly applies to the practicality of the LM 500h.

Every day I discovered new compartments, tray tables and storage areas. There are so many cabinets, lockers and hidey holes that we almost left my belongings (an entire family of plushie toy capybaras) behind because there are so many places to check.

Of course, I'm talking about the rear compartment here because up front there's not much storage. In fact, it proved to be quite a problem in that I had nowhere to put my bag with somebody sitting next to me and no area behind the front seats to stow it, either.

Talking of seats, the LM 500h only has four of them, with two up front and two in the rear. Up front, the seats are supportive and large, but the rear seats - those are, well... have a look at the images.

We’re talking two large captain's chairs that look as though they’ve been removed from the first class section of a plane.

And while this might be suitable for businesses shuttling a couple of executives to and from meetings, for a family, even with two children, the extra couple of seats a third row offers would come in handy.

The LM 350h has seven seats over three rows and no privacy screen. A far better choice for families.

For device charging there are USB ports up front and in the rear. There are wireless phone chargers for those in the back seats but not up front.

The LM 500h has a cargo capacity of 752 litres with all seats in place.

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.

Believe it or not, the shiny beast you see in this review is the entry-level Lexus GX, the 550 Luxury, which lists at $116,000, before on-road costs.

Now be warned, according to Toyota’s website, that translates into more like $128,000, drive-away (in NSW). It’s also a long way above the entry-level Toyota Prado, the GX, which lists at $72,500.

But something, something, something ‘premium’, I guess. And besides, you do get a whole lot of stuff — and a whole lot of engine — for your money. 

The entry-level GX nabs 20-inch alloys with a full-size spare, LED lighting all around (including DRLs and fog lights), front and rear scuff plates, roof rails and a powered tailgate hinged at the top, rather than the side.

Inside, there’s seating for seven, wrapped in synthetic leather, heated and ventilated front seats, and heated window seats in the second row. There's also three-zone climate, a 14-inch central screen with wireless Apple CarPlay and Android Auto, a 10-speaker stereo, a 12-3-inch driver screen, a head-up display and wireless device charging.

The Sports Luxury is the most expensive GX at $128,200, before on-roads, and it gets 22-inch wheels, adaptive suspension, better lighting and a fixed glass roof with a sun shade. Inside, there’s a 21-speaker Mark Levinson stereo, leather seats with a massage function for the front row and a digital rear-view mirror amongst other added goodies. 

Then smack-bang in the middle of the GX range is the Overtrail, which lists at $122,250, and is designed to be the most off-road-focused model of the lot.

It rides on 18-inch alloys, gets special 4WD-focused bumpers and provisional mounts should you want to install rock rails. There’s also an electronic rear diff lock and what Lexus calls its 'Kinetic Dynamic Suspension System', which automatically disconnects the front and rear sway bars for serious wheel articulation when off-roading.

Inside, it’s a five-seat-only deal, with a synthetic suede seat material and unique design treatment.

The LM 500h is a petrol-electric hybrid with a 2.4-litre four-cylinder turbo-petrol engine which makes 202kW/460Nm and works in concert with two electric motors.

The front motor makes 64kW/292Nm and the rear makes 76kW/169Nm. The combined maximum power output of the two motors and the petrol engine is 273kW.

The LM 500h is all wheel-drive and has a six-speed automatic transmission.

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.

Lexus says after a combination of urban and open roads the LM 500h should use 6.6L/100km. In our own testing we found consumption was higher at 9.4L/100km.

Worth noting my driving environment was mainly a hilly suburban one filled with school drop offs. Achieved some personal bests this week, with one long run to Sydney’s outskirts, only to return in nightmarish peak hour traffic.

Premium (95 RON) fuel is required and the tank size is 60 litres. In theory the driving range is a smidge more than 900km, which drops to around 640km using our real-world average.

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.

Quite simply, driving the LM 500h is like piloting a limousine on stilts. Superbly comfortable, but with an elevated driving position that offers outstanding forward and side visibility, the LM 500h is an easy vehicle to drive for long periods of time.

A digital rear vision mirror means visibility behind is good and unobstructed by the privacy screen or the seats.

The drawbacks are down to the lack of space up front, with the driver’s chair limited in its ability to recline or slide back due to the bulkhead behind it.

And that's compounded by the lack of cabin storage for bags if the front passenger seat is taken.

As for the rear passengers there aren't many people movers offering this level of comfort, except perhaps the Zeekr 009.

Variable suspension that adjusts continuously keeps the vehicle composed and provides a high level of comfort for those in the rear. At the same time, the LM stays nice and flat through roundabouts while remaining civilised over speed bumps.

And then there's the acceleration, which, while not supercar-like is incredibly brisk for a van. The all-wheel drive system provides outstanding traction in wet and slippery conditions, too. 

Our family used the LM daily for everything from school runs to shopping trips and weekends away and not only was it fun to drive, our lucky rear passengers enjoyed sitting high and being able to see clearly out their windows along with the luxury of a giant movie screen.

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.

The GX features a long safety list (think AEB, lane keeping assist, rear cross-traffic alert, etc), and while not yet ANCAP tested, I’d be surprised if it didn’t nab a strong rating.

But I want to call out one feature you’ll love, especially if you’re nervous about driving a bigger vehicle.

It’s technically an off-road camera, which fills the 14.0-inch central screen with exactly what's happening beneath the tyres, but it also comes in plenty handy when parking.

Basically, the GX disappears from the 360-degree bird's-eye view, meaning you can see exactly where the parking lines or lane markings are.

The airbag count runs to nine, including full-length side curtains and there are three top tethers and two ISOFIX anchors across the second row for securing child seats and/or baby capsules.

Lexus covers the LM 500h with a five-year, unlimited kilometre warranty. 

The Lexus Encore Platinum program is complimentary for LM owners for three years, providing 24-hour roadside assist, a loan vehicle or pick-up/return service at service time, 'On Demand' vehicle evaluation options, valet and airport parking benefits as well as exclusive offers and event opportunities.

Servicing is recommended annually or every 15,000 kilometres, and impressively, pricing is capped at $695 per service over five years.

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.
