Lexus LM review

There are few better examples of the phrase "It’s what's on the inside that counts" than the Lexus LM. You see, while the exterior looks like a Lexus MPV with a rather radical grille, the interior is inspired by the world of private jets.

There are two versions to choose from – a four-seater and a seven-seater – and each serves a slightly different purpose. The more you pay, the fewer seats you get, so the range opens with the seven-seat LM model, which has similar appeal to the Mercedes V-Class. In other words, it should be ideal for providing very comfortable transfers from airports.

The top-spec four-seater – called the Takumi – is solely concerned with trying to be the most luxurious MPV you can buy, treating you to huge reclining seats and a whopping great 48in entertainment screen. Much like the BMW 7 Series, the Mercedes S-Class and the long-wheelbase Range Rover, it aims to transport VIPs in private-jet style without leaving the ground.

To help it achieve that, Lexus has equipped the LM with a myriad of standard equipment, including a pair of huge reclining and massaging captain’s seats, a built-in fridge and a whopping great 48in entertainment screen for the pampered back-seat passengers.

It’s fair to say that the Lexus LM’s main appeal will be to companies chauffeuring the rich and famous around, but can it really compete with the established competition from Mercedes and Range Rover? Read on to find out...

The Lexus LM comes with a 247bhp 2.5-litre hybrid petrol engine as standard. If you go for the seven-seater, you can choose whether you want that power to go to two or four wheels, while the top-spec Takumi four-seater is only available with all-wheel drive.

Given the weight of the LM, it’s not surprising that neither version is quick, with a 0-62mph sprint time of 9.0 seconds – or 8.7 seconds for the Takumi.

That's not really an issue, though, because it’s not the kind of car that makes you want to put your foot down (you wouldn’t want your passengers to spill their champagne, after all), and there's enough power for smooth driving.

This bias toward smooth and comfortable driving rather than pace can be felt through pretty much every part of the LM. For example, the brakes use a system called "braking posture control", which actively spreads braking pressure between the front and rear wheels, to ensure those in the back are not jostled around. 

Likewise, the soft suspension has been designed for maximum comfort. It does a good job at it, too, taking the sting out of potholes and imperfections and limiting vertical movement well when driving normally. It doesn’t have the body control of the firmer BMW X7 and you’ll feel your head being gently swayed from side to side over undulations but, provided you don’t chuck it around corners, it’s never unpleasant. 

You get lots of different driving modes to help, including the usual comfort and sport modes, which change the firmness of the suspension and the engine’s response. For the first time in a Lexus, there's also a "rear comfort mode", which prioritises the comfort of back-seat passengers over the driver. 

The LM has well-weighted steering that gives you a good sense of what the wheels are up to, but doesn't feel even slightly as dynamic as a BMW X7 or a Range Rover. Of course, that’s not really the point of the LM and you won’t find that it puts you in the mood to drive with any particular vigour.

Refinement wise, the LM is, for the most part, very relaxing thanks to wind and road noise being brilliantly suppressed. Around town, there’s often no engine noise because the LM's hybrid system allows it to run on electricity alone at slow speeds.

The problem comes when you need to speed up and the engine kicks in. The LM uses a CVT automatic gearbox which causes the revs to soar when you put your foot down and then remain high until you ease off again. The result is lots of engine noise as you accelerate, shattering the calm atmosphere. It's arguably the only thing about the LM that doesn’t fit the brief.

As you might expect, it’s when you sit inside the Lexus LM that it really shines. Every surface is covered with either supple leather or quality-feeling wooden trim, and you’ll have to search exceptionally hard to find any kind of scratchy or cheap-feeling plastic. 

In short, you’ll be hard pressed to find any other car that’s more pleasant to be in. Indeed, the Mercedes S-Class could learn a thing or two from the LM – and not just when it comes to material quality.

The LM’s construction feels far sturdier than that of the S-Class, with switches that feel satisfying to press and surfaces that give the impression they'll endure years of VIP chauffeuring.

Naturally, along with all the plush materials, Lexus has placed a lot of focus on rear-seat comfort. In the back of the LM (or the middle row of the seven-seat version), you’ll find two seats that seem to have come straight from the first-class cabin of a swanky airliner.

They’re big, especially in the four-seater, and have loads of electrical adjustability, including for lumbar support. The four-seat version is the most impressive, giving you the ability to lay them flat like a bed. You can adjust the seats in both with traditional physical buttons or by using the iPhone-style control tablets on the rear centre console.

While we’re on the subject of those tablets, they do more than just adjust the seats. In fact, you can use them to control pretty much everything in the back of the LM – from the climate control and seat massages to what’s playing on the all-singing, all-dancing infotainment system. 

The size of that system's screen depends on which version you’re in. In the seven-seater you’ll find a 14in screen that folds down from the roof, while in the four-seater you’ll find a vast 48in high-definition widescreen.

That’s even bigger than the 31in screen you can get in the BMW 7 Series and the all-electric BMW i7 – and because you're further away from it than in the i7, it’s more comfortable to watch for long periods.

Both screens in the LM allow you to stream content from your smartphone or via an HDMI cable, but getting them to work can be a little fiddly – especially when it comes to connecting your device wirelessly. Once it is sorted, audiophiles will be delighted by the standard 21 or 23-speaker bespoke Mark Levinson surround-sound stereo fitted to every LM. 

So, it’s no secret that the LM is catering for those in the back seats, but what about the driver? Well, for starters, the high driving position gives a commanding view of the road ahead and cut-outs in the front pillars ensure you can see out easily at junctions. In that respect, it’s very reminiscent of the VW ID Buzz. 

You don’t see much over your shoulder, but big wing mirrors and standard-fit blind-spot assist help to combat that issue. You can’t see anything out of the back window either, so all versions come with a digital rear-view mirror that shows a clear view of what’s behind you from a camera on the rear.

On top of that, standard-fit front and rear parking sensors, rear-view camera and handy top-down view make parking a doddle. A 14in infotainment touchscreen with built-in sat-nav, and Android Auto and Apple CarPlay smartphone mirroring ensures you’ll always know where they’re going. 

Annoyingly, the seven-seat LM gets a steering wheel with touch-sensitive pads to control the cruise control and audio, and they’re both far fiddlier than the proper physical buttons that you’ll find in the four-seater.

Up front, the driver and passenger are treated to loads of head and leg room, so even those over six feet tall won’t complain that they don’t have space to spread out. Likewise, the Lexus LM is wide, so there’s loads of shoulder room between the two.  

Front storage is generous, providing those up front with a wireless charging cubby for a mobile phone, large door bins, a big glovebox and a deep cubby underneath the central armrest. 

Again, though, it’s in the back where the LM impresses most. You see, the LM’s shape gives it an advantage over its saloon rivals because the roof doesn’t slope to the rear or encroach on head room. No matter which version you’re in or how tall you are, you’ll never feel cramped. 

Leg room depends on which version you go for. Neither will be cramped for a six-footer, but the four-seater’s rear seats are set closer to the rear of the car and give you loads of rear space – more than you’ll find in the BMW 7 Series and BMW i7, the Mercedes S-Class or the long-wheelbase Range Rover. What’s more, the large windows and boxy shape of the body make for a space that feels generally cavernous.

Even those sat on the seven-seater’s third row will find that there’s plenty of head, leg and knee room, and certainly more than in the third road in a BMW X7. You get three seats back there, but realistically there’s only enough space to fit two people side by side – three would be a real squeeze. 

There’s loads of rear storage space in both versions of the LM. The four-seater even has a decent-sized fridge hidden in one of its cubbies. 

The two rear seats in the four-seat version can’t slide them back or forth, and because they're set further back than in the seven-seater, there's less boot space – 752-litres against 1,191-litres. Either way, that's still a lot of space for luggage. 

Better still, there’s only a very small drop down to the boot floor, which itself is perfectly flat. Our only demerit would be that the boot lid is massive, opening out a long way and sitting high when fully opened.

As a cash purchase, the entry-level seven-seat Lexus LM looks pretty punchy, costing quite a lot more than the equivalent Mercedes V-Class. It is, however, not that much more expensive than the BMW X7 and will cost you much less than a seven-seat Range Rover. 

The four-seater is far more expensive, getting closer to the Range Rover’s price tag and costing around the same as a well-specced Mercedes S-Class. You can’t avoid the fact that it’s much more expensive than any other MPV out there, although none of them will offer the same amount of luxury. 

What’s more, the LM is predicted to depreciate quite slowly, helping to protect your investment and ultimately meaning you’ll likely get more of your money back if you decide to sell in three years. That said, the Mercedes V-Class is predicted to lose its value slower. To get the best price whatever you decide on, make sure you take a look at our New Car Deals pages. 

Lexus currently has no plans to create a plug-in hybrid (PHEV) or electric car version of the LM, which could be a problem for companies hoping to operate them as VIP transport in the middle of cities. Indeed, with clean air zones appearing more and more throughout the country, those companies might instead prefer an electric luxury car such as the BMW i7 or the Mercedes EQV.

Likewise, despite the LM’s hybrid engine managing to keep CO2 emissions down, company car drivers chasing low benefit-in-kind (BIK) tax payments will be better off with the Range Rover PHEV or, again, an all-electric rival. 

Which version of LM you go for will largely depend on your needs, but you can be sure you’ll get lots of standard equipment whichever you pick.

Even the entry-level version comes with 19in alloy wheels, a head-up display, a 21-speaker Mark Levinson sound system, a 14in drop-down rear monitor with HDMI, dual-zone climate control, a heated steering wheel and lots of other kit. 

For ultimate luxury, though, you’ll want to step up to the LM Takumi version. That adds the upgraded 23-speaker stereo and 48in widescreen rear monitor, two folding tables in the rear, a dimmable glass partition between the front and rear, and the two airline-style rear seats with seven massage functions.

When it comes to reliability, the LM is too new to have featured in the 2024 What Car? Reliability Survey but Lexus – as it usually does – did well, coming second out of 31 brands. 

Better still, if anything were to go wrong, Lexus offers an extremely generous warranty of 10-years/100,000-miles, providing you always service at an approved service centre. Only Hyundai’s five-year warranty and Kia’s seven-year warranty get anywhere close to that offering. 

The LM is yet to be tested by the safety experts at Euro NCAP but it has plenty of standard safety features to put your mind at ease.

All versions come with automatic emergency braking (AEB), a driver monitor, lane-keep assist, lane-change assist, front cross-traffic assist, blind-spot monitoring and road-sign assist.
