BMW XM vs Volvo Es90

What's the difference?

It’s pretty obvious the XM is designed to impress people with big wallets and an appetite for a techy experience that’s also not without a few green credentials. The ability to motor around as a fully-electric vehicle for up to 80km or so is a big plus and the electric-ballroom interior vibe is hard to ignore, as well.

But from our perspective, the full-fat, twin-turbo V8, while offering startling performance, is perhaps a lost opportunity to follow some of BMW’s competitors into the engine-downsizing space. Then again, when you floor the throttle and 2700kg hurtles forward like a big dog on a short chain, you can see where BMW is coming from.

Perhaps the biggest letdown is the ride quality – or lack of it. While it’s understandable BMW wanted the most dynamic version of the XM it could manage, the end result plays against the vehicle’s otherwise long suit of hyper-luxury. Doubtless, BMW would argue that to soften the chassis would have been to introduce a chink into a no-compromise product. But, perhaps, sometimes a sensible compromise is the way forward.

More stylish than ever before, as quiet and refined as you'd expect from a luxury car and yet the stand out feature might once again be safety. Despite seemingly every new car being loaded to the gills with safety features, Volvo has managed to demonstrate industry best-practice and leads the way again.

I would encourage engineers from every other car brand to drive the ES90 to learn how to better integrate the modern suite of active safety features like forward collision warning and lane departure warning.

But beyond that, is the ES90 a car worthy of consideration? Well, pretty much everything it does the EX90 does too, so if you prefer an SUV that’s definitely worth consideration. But if you don’t want an SUV, if you prefer a sedan or just love to be different, the ES90 is a very attractive proposition in more ways than one.

There’s nothing subtle about the way the XM looks. It probably pulls up just short of brutalist (or maybe not) but even those who find its slabs and angles attractive have to admit that it’s bold.

The now-trademark giant nostrils set the mood and the rest of the exterior suggests some kind of armoured transport for presidents rather than wheels for the school run. Doubtless, this will hardly be seen as a fault by those in the market for such a thing.

The real surprise here is that the XM does not share a bodyshell with any other production BMW. Sure, the V8 petrol engine and wheelbase are common to other BMW and M models, but the sheet metal is the XM’s and the XM’s alone. That in itself, is quite a statement of intent.

Discussing Volvo design will draw different opinions depending on your age. As a millennial, I grew up at a time when Volvos were, to quote a famous movie line from the 1990s, ‘boxy, but good’.

But over the past two decades Volvo has smoothed off those boxy edges and become one of the most style-conscious car companies in the world. It has embraced its now-unique place as a Scandinavian carmaker and uses softer edges and more Nordic design themes (such as light coloured interior woods) to ensure the ES90 is simply a good-looking car.

What it isn’t, at least not technically-speaking, is a sedan. That’s because it has a liftback rear-end design, rather than a traditional ‘three-box’ sedan with a conventional boot. That shouldn’t be a deal-breaker for anyone and it means it’s a far more practical design.

It also sits taller than a conventional ‘sedan’, which is an increasingly common trait for modern European sedans as they try to woo would-be SUV buyers. It’s not a lot, you certainly wouldn’t call it a tall or high-riding car, but it is noticeable.

Ends up as an ‘in-between’ design, neither one thing or the other. The closest thing it reminds me of is the short-lived BMW 5-Series GT, which is damning with faint praise, but it speaks to the challenge of making something that simply isn’t an SUV appealing to the modern SUV-obsessed market.

The very stylish cabin features that previously mentioned light coloured wood (at least in our test car) and that unique Scandinavian look. It’s the closest you’ll get to sitting in a Swedish lounge room on wheels.

Given the vast exterior dimensions and a weighbridge ticket the wrong side of 2700kg, it may come as a surprise to learn that the XM is strictly a five-seater with not even an optional third row.

That said, the uber-SUV Lexus LX in flagship, Ultra Luxury, trim offers just four seats in deference to the VIP clientele it’s pitched at, but also comes complete with reclining rear seats and a passenger’s side footrest which the XM can’t match.

Staying in the rear seat, there’s lots of legroom and plenty of space under the front chairs for feet. A lot of that is down to the wheelbase the XM shares with the BMW X7, and even behind a tall driver, there’s lots of space. In fact, compared with a BMW X5, there’s a full 150mm of extra legroom.

The pew itself flows into the door trims for a lounge effect which looks great with the contrasting light-coloured trim, and the centre arm-rest folds down to reveal a pair of cupholders. Extra storage space can be found in fold-out pockets in the rear of each front seat which also house a small, lidded panel that opens to reveal USB ports and power sockets. Dual-zone climate controls are also part of the rear-seat experience.

The gee-whizz stuff hasn’t been ignored, either, and the prismatic roof lining is nothing if not a talking point. But would a panoramic sunroof have been of more value to many buyers? The ambient lighting is a nice touch, too.

Up front, the view is dominated by the giant, twin curved animated dashboards. They deliver information and lots of it, to the point where it can almost seem a bit overwhelming.

The head-up display helps simplify things, but there’s absolutely no doubt there’s a lot going on in this cabin. Again, this is modern luxury motoring, but it remains that the menu system will take time to learn, even if the touchscreen function gives you an option on how you control things.

Multi-adjustable front seats are part of the deal and there’s an M-spec steering wheel which is heated. And although it features plenty of buttons, isn’t as daunting perhaps as the multi-spoked equivalent in some high-end AMGs of late.

The stereo system is also worthy of a mention, being a Bowers & Wilkins unit with roof mounted speakers and no less than 1500 watts of power. Digital radio is part of the package.

Even though it doesn’t offer a seven-seat option, luggage space in the rear of the XM is hardly class-leading. Cargo volume with rear seat up is 527L and 1820L with it folded.

Much of the wheelbase is devoted to rear-seat stretching room and although the batteries for the electric motor are positioned under the rear seat, the floor of the cargo area seems quite high.

In terms of space the ES90 is very generous, which it should be given it's a five-metre long car. There’s loads of room front and the back so you’ll seat four adults in absolute comfort, and can squeeze in a fifth if needed. Thanks to the relatively flat floor, as well as the panoramic roof that can either be opaque or clear, the cabin feels spacious and bright even in the rear.

As for luggage space, the boot measures 424 litres, and obviously it’s very easy to access via the power liftgate. But it’s still not as big as an SUV. The EX90 offers up 655 litres of space in its five-seat configuration. Which is at least a small part of the explanation why SUVs have become the more popular choice.

But what really stands out in the cabin isn’t the space, it’s the technology. The ES90 Ultra’s multimedia system is centred around a 14.5-inch touchscreen that runs all the car’s key functions; you also get a 9.0-inch driver’s display.

Notably, Volvo has opted to offer Google’s operating systems built-in, which means while you can still run Apple CarPlay or Android Auto, if you have a Google account you can sign-in and have your contacts, address book and other details integrated into the car.

It’s a really fast system, too, supported by the most powerful software Volvo has ever put inside one of its cars. Having a big tablet-style screen is great and feels very modern, but if it runs slowly, with lag between commands, it’s not as useful. This Volvo system, particularly the transitions between menus and even the voice assistant, reacts with lightning-fast speed.

Then there’s the sound system we mentioned earlier. It’s a 25-speaker Bowers & Wilkins set-up with 'Dolby Atmos' and an app called Abbey Road Studios. This app has been produced in conjunction with the iconic recording studio made famous by The Beatles. The speakers and the app were all developed together to provide a superior audio experience.

The speakers themselves are incredibly powerful while staying crystal clear, with the Abbey Road app providing the ability to change the sound between 'Modern' and 'Vintage' settings that make you feel like you’re inside a recording studio.

Put simply, it is as impressive a sound system as I’ve ever experienced in a car.

The ES90 range consists of two models at the time of publication both powered by a single, rear-mounted electric motor, with the twin-motor option available on the EX90 SUV currently not offered in Australia (emphasis on the word ‘currently’).

The range begins with the Pure from $88,880, before on-road costs, and is completed by the current range-topping Ultra variant, which we're testing, priced from $107,990, plus on-roads.

That means it’s cheaper than its direct rivals in the luxury electric sedan market. Audi’s e-tron GT starts at more than $200,000, the BMW i5 line-up is priced from $155,900 and the Mercedes-Benz EQE range begins at $134,900. So, even with this more expensive Ultra variant, Volvo has a clear head-start on the competition.

And Volvo hasn't managed that by skimping on standard equipment. The ES90 comes loaded with adaptive air suspension, 22-inch alloy wheels, a comprehensive safety package (as you’d expect from Volvo) as well as an electrochromic panoramic roof, a smart key you can add to your phone and 'Nordico' upholstery - Volvo’s sustainable synthetic leather.

There’s also a 25-speaker Bowers & Wilkins sound system, but more on that later…

Here’s where the XM starts to justify its price-tag. While the use of an electric motor to boost a petrol engine has allowed some manufacturers to reduce the capacity of the latter, no such restraint has been shown for the XM. Instead, it gets the full 4.4-litre, twice turbocharged V8 that we’ve come to know and love from this brand.

It’s not that this is the engine’s first date with hybrid technology, but the mild hybrids that have come before it can’t match the XM for sheer brutality when both power units are unleashed.

The petrol V8 can muster up 360kW and 650Nm which, when boosted by the electric motor, jumps to a total of 480kW (combined) and 800Nm.

While the petrol engine drives through an eight-speed torque-converter automatic, the electric motor also drives through the transmission, an arrangement that is a bit different to some hybrids which use the petrol engine for the rear axle and the electric motor to drive the front wheels.

Of course, the requirement for the XM to feature permanent all-wheel drive, regardless of what power unit is running at the time, forces this layout.

Speaking of all-wheel drive, The XM’s version of BMW’s 'xDrive' layout has been specifically tuned for this vehicle and includes torque vectoring as well as a limited-slip rear differential.

The system has the ability to vary the torque split front to rear, with the default rear-bias giving a more sporting feel on good surfaces. An active rear differential also helps give the car a rear-drive feel.

As well as modes for 'Hybrid', 'Electric' and 'eControl' modes, the XM sticks with the M tradition of offering two M buttons which can be configured to set the parameters for steering, driveline, chassis and, in the case of the hybrid XM, the degree of braking regeneration offered.

Four-wheel steering is also part of the XM’s repertoire and, interestingly, there’s no air suspension here; just conventional steel springs.

But it does feature an electrically-adjusted anti-roll bar system which aims to strike a happy medium between what the driver wants and the road conditions demand.

As the name suggests, the ES90 Single Motor is powered by a single, rear-mounted electric motor that drives the rear wheels via a single-speed transmission. The motor makes a healthy 245kW and 480Nm, so the 0-100km/h sprint time is 6.6 seconds - sprightly for such a big car.

As alluded to earlier, there is a Twin Motor, all-wheel drive ES90 variant available in overseas markets, with 500kW, but Volvo Australia is yet to confirm when, or even if that will arrive here.

A 25.7kWh lithium-ion battery provides the power for the electric drive. It’s mounted under the rear seat and can produce a purely electric range of between 82 and 88km (based on WLPT test protocols).

Charge time from a conventional wall-box is said to be about four hours but, interestingly, the XM has no provision for DC fast-charging.

Fuel consumption (combined cycle) is an EV-typical 2.7 litres per 100km, which equates to a low 61g/km of CO2.

Once you’ve depleted the battery on a highway journey, expect the petrol V8 to consumer somewhere between eight and nine litres per 100km at cruising speed.

Using EV mode means zero-emission operation but, as with any electric car, how the power is generated to recharge it determines its real-world green-ness.

Built on Volvo’s 800-volt electrical architecture, the first Volvo to feature the technology, the ES90 is powered by a 92kWh battery that provides up to 554km of driving range on a single charge.

Volvo quotes an NEDC energy consumption of 18.5kWh/100km, with 300kW DC charging able to take the battery from 10 to 80 per cent in 22 minutes. A full, empty to 100 per cent charge using a 16A outlet will take 10 hours.

It should be noted that the EX90 SUV will be upgraded to the 800V architecture with the 2026 model year introduction.

While any M car is supposed to be rapid and dynamic, it’s also true that the over-arching perception of big SUVs is that they’re comfortable and plush. None of which explains the ride in the XM.

Regardless of how you fiddle with the settings, the ride is always brittle. Those big tyres with their minimal sidewall somehow manage to find every crack and join in the road, and it’s these sharp-edged imperfections that thump through to the cabin the most vocally.

It’s enough to make you wonder who this car is going to appeal to. Will it take to race tracks? Almost certainly not. So the whole point of these suspension settings might be a bit lost on some people.

Performance, meanwhile, is insanely rapid for something that could pass as a bulk carrier. The biggest giveaway to the mass is the transmission’s earnest attempts to keep everything moving by feeling a bit hyperactive on downshifts.

Using the ratios is always going to be the strategy, but with all that torque, maybe it’d be nice sometimes for the trans to hang on to a taller gear and let the boost blow it towards the next corner.

The sound track? Polarising. Even if it doesn’t convince you that Hans Zimmer (who developed the various electronically-synthesised noises the XM makes) should stick to winning Oscars, the augmented sounds are background noise rather than the main event here.

Even the petrol V8’s naturally stirring backing vocals have been electronically tweaked with debatable results.

That said, it’s nice to have something to listen to that isn’t the insistent tyre roar which becomes even louder on coarse-chip surfaces.

Steering effort is light but there’s not a lot of feedback in terms of actual feel. In fact, it’s borderline detached and only the sheer speed of the rack confers any athleticism.

Also, the rear steering seems to come in a few milli-seconds after the front has started to turn. And for all that all-wheel-steering agility, this is never a car that shrinks around you.

As you’d expect from a luxury, electric car the ES90 is a quiet and refined vehicle to drive. Being a Volvo, the company has used its experience where it matters, and there is excellent insulation from the outside world. Unlike some EVs that lose the engine and hope that just makes things quieter, the ES90 gives you a genuine feeling of insulation from the exterior hustle and bustle. 

Performance is adequate from the single motor but it’s by no means a sports sedan with only 250kW/480Nm and such a big vehicle. But it has the instant response that is an EV trademark so it has all the performance this type of car and the drivers it will attract would likely need. If buyers start banging on the door for more power, Volvo can oblige, but for now it does the job you expect of a luxury four-door.

While it has the sedan silhouette, the taller body and raised ride height on the air suspension are noticeable. You will find yourself looking up at SUV drivers, but not all of them. It’s roughly the same seat height as you’ll find in a modern small SUV, so a slight elevation rather than a big boost.

The ride is what you expect from this type of car. You can adjust the suspension and steering between ‘soft’ and ‘firm’ settings, but even with the latter selected there is a lot of compliance and the ride remains comfortable.

The steering is fine most of the time, but when you have to do parking maneuvers you certainly notice the ES90's steer-by-wire technology. The steering literally feels like an old computer game steering wheel set-up, with very little resistance as the wheel lightly spins from lock-to-lock. It’s not a bad feeling, but it is a bit odd and takes some getting used to.

The ultimate take-away from the driving experience is just how relaxed it is - quiet and effortless are the two words that probably best sum it up.

This is obviously the area that Volvo is famous for, but with seemingly every other brand forced to raise their own safety features over the years, does the Swedish brand still do anything special on this front?

Absolutely.

Put simply the Volvo suite of active safety systems is better developed and better integrated. Every rival car to the ES90 will have a similar list of features, including adaptive cruise control, forward collision warning, lane departure assist, road sign information and more. But Volvo has made it work so well that unlike rival models, you never even think of turning them off, they don’t beep and bong ad nauseum, they only work if you need them in an emergency - which should be the standard.

One thing to note is the ‘bump’ on the roof (you may see in the images) to house a Lidar system. However, Volvo split with its supplier and has decided to abandon this technology for the ES90. That means the 2026 model year examples will not have the roof bump, but still come loaded with five radars, seven cameras and 12 ultrasonic sensors for the excellent coverage of the surrounding environment.

The only thing that stops the ES90 being worthy of a 10/10 safety score is the lane keeping assist could do with some fine-tuning, as it has a tendency to move in the lane slightly too much.

There is no current ANCAP score for the ES90, but the EX90 SUV does, and given the organisation's previous sharing of scores between different models based on the same core underpinnings, there is no reason to believe the ‘sedan’ wouldn’t be just as safe.

Like a lot of manufacturers, BMW knows consumers can be leery of EV tech when it comes to the cost of battery replacement. So, as well as the five-year/unlimited-kilometre warranty on the whole vehicle, there’s also eight years or 160,000km of cover for the high-voltage battery.

Servicing intervals are based on how the car has been used and it will inform the owner when a service is required.

A servicing package is included in the purchase price and BMW even throws in three years of roadside assistance.

The ES90 is covered by Volvo’s five-year, unlimited kilometre warranty, which is competitive for the luxury market even if it’s shorter than the cover some mainstream brands offer.

Servicing costs are currently unclear, at the time of publication. Volvo Australia typically offers five-year servicing plans for its models but is yet to finalise the cost for its electric vehicles.

Despite its long history in Australia, Volvo still has a relatively small footprint in this country with only 28 dealers/service centres spread across the country. However, more are planned to expand that coverage in the coming years.
