Hyundai Imax vs Lexus LM 500H

What's the difference?

It looks a bit old-fashioned in a ‘Tarago’ sort of way and is starting to show its age with a five-speed transmission and in lacking some of the latest safety features. However, if you need to regularly transport up to eight people and expect good comfort, economy, performance, practicality, reliability and warranty as part of the deal, then the iMax still has more than enough going for it to justify top three positioning on any people mover shopping list.

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. 

Compared to the Kia Carnival, which looks like tomorrow’s people mover today, the iMax is looking more like yesterday’s as its tall and minibus-like dimensions are immovably defined by its iLoad commercial van birth twin. Even so, there is still plenty of practicality and ease-of-use inherent in this traditional design, including a bright and airy cabin with generous headroom for all.

The iMax rides on the same 3200mm wheelbase as the iLoad and shares many of its key dimensions along with power-assisted rack and pinion steering and four-wheel disc brakes. However, to provide better ride quality than the van’s leaf springs, for human cargo the iMax’s multi-link live rear axle rides on plusher coil springs. The Series II upgrade also includes restyled 16 x 6.5-inch alloy wheels shod with 215/70 R16C tyres and a full-size steel rim spare.

The large front doors open wide for easy entry and exit and with no console between the front seats the driver and front passenger can literally walk through to the passenger area. Sliding doors on each side, with large windows that can be propped open for extra ventilation, allow generous access to the second and third row seating. These bench seats provide ample head room and adequate shoulder and legroom for medium-sized adults, even with three across the back row, which is a refreshing change from many SUVs that treat third-row adults as extra baggage.

There’s also ample ventilation, with roof and floor-mounted air vents for the second and third rows linked to a separate control panel which allows passengers to adjust the fan speed and air-con temperature independent of the driver. Combined with generous headroom and large rear passenger side windows which can also be propped open, the iMax succeeds in minimising claustrophobic feelings particularly for those in the back row.

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.

The iMax’s hefty kerb weight of 2230kg and GVM (gross vehicle mass) of 3030kg allows for a payload of 800kg and up to 125kg of that can be carried on the roof with a three-rack system. Eight average-sized adults on board would use up most of this payload capacity, so if they need to bring luggage it could easily surpass the payload limit. 

It’s also rated to tow up to 1500kg of braked trailer and with a GCM (gross combined mass) of 4530kg it can carry its maximum payload while doing it. However, you also need to keep in mind that the 150kg tow-ball download limit is included in the total payload, leaving 650kg rather than 800kg to play with. Even so, any vehicle that can tow its maximum trailer weight with a full payload gets a big tick from us, particularly one with a cavernous (VDA) 842 litres of cargo volume available behind the third row of seats.

An impressive array of storage solutions includes dual map pockets and a single bottle holder in each front door, a dash top storage compartment, dual glove box compartments, central dash dual retractable cup holders and an overhead felt-lined sunglass holder. Those seated in the second row get dual map pockets and single bottle holders in each sliding door plus mesh-type storage pockets on the rear of each front seat, while third row outer passengers get storage recesses and cup holders.

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 Lexus LM 500h sits at the top of its range and is without a doubt one of the most expensive people movers on Earth with its list price of $220,888.

As you would imagine the standard features list is as extensive as it is extravagant.

For starters, while the regular LM 350h has two rows of seating in the rear (seven seats all up, including the front two), the 500h has the third row removed and just two super luxurious and enormous fully reclining seats fill the entire space. It’s like a theatre back there.

That theatre theme keeps going with a media screen in the back so large it stretches the width of the vehicle. Seriously, it's a 48-inch screen to watch movies or connect to your device.

The sound system is probably the best I’ve experienced - a spine tinglingly incredible 23-speaker Mark Levinson set-up.

What else can I tell you? Those rear seats are upholstered in beautifully soft semi-aniline leather. They’re heated and ventilated with a massaging function and... ridiculously comfortable.

There’s four-zone climate control, windows which have an electronic shade that turns the glass opaque, there are wireless phone chargers in the doors and carpet throughout so thick you sink down into it as you step inside.

Our LM 500h was upholstered in the 'Solis White' leather which also brings contrasting and mesmerising copper metallic trim.

Oh, and there’s a wall with an electric glass screen that can be raised or lowered to separate the rear passengers from the driver.

I should have mentioned this earlier. The kids loved it, but these parents spent a lot of time telling the 10- and three-year old not to put the screen up again.

The rear occupants, aka the kids, can also lock the screen in place. Which they did, and so sound proof is the dividing wall that we can only just hear their uproarious laughter.

Up front, the cockpit is comfortable but it’s clear all the space and luxury is for those being driven around.

Still, the front seats are leather with heating and ventilation, there’s a 14-inch media screen and 12.4-inch digital instrument cluster, plus a head-up display. Sat nav, Apple CarPlay and Android Auto are also standard.

The iMax shares the same 2.5 litre common rail four cylinder turbo-diesel found in the iLoad and it’s just as well suited to moving people as it is to shipping heavy cargo. With 125kW at 3600rpm and a bountiful 441Nm of torque peaking at 2000-2250rpm, this refined and torquey engine uses its variable vane turbocharger (VGT) to good effect with great flexibility through the rev range.

The five-speed automatic with sequential manual shift option is the only transmission available with this engine and they are well matched. The torque converter’s stall speed and low 3.730 first gear combine with the 2.929:1 diff ratio to provide lively response from standing starts, making it well suited to stop-start city and suburban duties. The overdriven fifth gear allows economical cruising at highway speeds.

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.

Hyundai claims a combined figure of 9.0 litres/100km but our numbers based on trip meter and fuel bowser readings came in at 11.8L/100km. Based on these ‘real world’ figures expect a fuel range of around 640km from its 75-litre tank.

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.

Impressive comfort, refinement and low NVH (noise, vibration and harshness) levels ensure the task of moving people is not a chore. The iMax is well designed for its specific role in life and gets the job done with a minimum of fuss. Loads varied from driver only up to six adult passengers during our test.

Although fitted with rear coil springs the tail stills feel a bit jittery over smaller bumps.

In city and suburban traffic it’s a surprisingly agile and energetic performer that belies its 2.2 tonne-plus kerb weight, with nicely-weighted steering, responsive braking and a sharp 11.22 metre turning circle.

Although fitted with rear coil springs the tail stills feel a bit jittery over smaller bumps and road irregularities when empty or lightly loaded, as those thick coils are designed to cope with a GCM of more than 4.5 tonnes. In other words, ride quality is at its best with a decent load on board.

Wind, tyre and engine noise are well suppressed. The resulting low cabin noise is a big bonus, particularly at highway speeds where conversations between front seat passengers and those in the third row can be conducted at normal voice levels. Along with its comfortable bench seating, this quietness makes longer journeys less tiring and more engaging for all passengers no matter where they’re seated.

Driver and front passenger comfort is excellent with all controls and dash contours thoughtfully placed.

The iMax’s tall highway gearing results in only 1800rpm at 100km/h and 2000rpm at 110km/h where maximum torque also resides. Driver and front passenger comfort is excellent with all controls and dash contours thoughtfully placed, plus supportive seating with inboard fold-down armrests. Those front seats provide a commanding view of the road and all external angles thanks to large door mirrors and a rear view camera.

Our only major gripes are that in wet weather the swept area of the left-hand wiper leaves the front passenger with more than half of their forward view obscured by unswept glass. It also shares the iLoad’s terrible static interference on AM band radio at times. And one iLoad feature we would like to see shared with the iMax is its automatic central-locking mechanism which locks all doors when vehicle speed exceeds about 5 km/h

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.

The Lexus  LM 500h is yet to be tested by ANCAP so it doesn't have a safety assessment score. There is, however, a high level of safety tech onboard including AEB which can detect pedestrians, cyclists, motorcyclists and other vehicles, emergency steering assist, lane keeping assistance, road sign recognition, rear cross-traffic alert, front and rear parking sensors as well as six airbags.

For child seats there are ISOFIX points and top tether anchor mounts on the two rear seats. We have a forward facing child seat and found it easy to install.

A space-saver spare wheel is located under the boot floor.

Standard warranty is five-year/unlimited km, with scheduled service intervals of 12 months or 15,000km, whichever comes first.

A capped-price servicing scheme is in place, with $349 the standard rate ($499 for 60,000km service only).

Roadside Assist is complimentary for the first 12 months, plus there's an optional Roadside Support Plan for up to 10 years, 'Lifetime Service Plan' and 'Sat Nav Update Plan'.

You can also expect a dedicated Customer Care Centre and the ‘myHyundai’ exclusive owner website.

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.
