What's the difference?
The world was ready for an Aston Martin SUV. Yes, by the time the Aston Martin DBX debuted Bentley had given birth to the Bentayga, Lamborghini had sired the Urus and even Rolls Royce had realised its Cullinan.
Still, the arrival of another ‘super SUV’ is always a bit exciting. Would it be a true Aston Martin, how would it compare to its rivals and is it even a good SUV?
Well, that's what I wanted to know about Aston Martin's DBX anyway, and I found out, along with everything else you should know: from its performance to practicality in this review.
BMW’s new XM is a tricky customer to pigeon-hole. Yes, it’s a huge, super-lux SUV and, yes, it’s all-wheel drive and features a station-wagon layout.
But it’s also a M-car and that infers super high performance. Weighing in one the wrong side of 2700kg, however, makes that a difficult task for any engineer.
This car also left us wondering if perhaps the glory days of M Division sports cars and coupes might behind it and SUVs like this one represent the road ahead.
But fear not: The CEO of M Division himself, assured us that the XM is a showcase for what an M badge can do, rather than a mission statement for the brand.
So, with that in mind, does this car have the wow factor that places it somewhere between peak oligarch and a motor-show concept car? Does it move the goal posts for big luxury SUVs? Does it even matter that it’s a plug-in hybrid?
As with all Aston Martins the DBX is a seriously beautiful car with that high-end exotic but restrained exterior styling for which the brand is known. As with all Astons, too, the busy interior design may put some minimalism fans off and those high-placed shifting buttons pose a functionality problem.
As an SUV the DBX is spacious and practical. You could use this daily as a family car. I did and found it easy to adapt to.
The driving experience left me disappointed. I didn’t feel the same close connection with the DBX while driving that I have had with other super SUVs, such as the Lamborghini Urus and more affordable models offered by Porsche and Mercedes-AMG.
But then, you see those other cars everywhere, unlike the DBX which is a rare and beautiful creature, despite the flaws.
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.
I'm not one to name drop but I was having a chin wag with Marek, that's Marek Reichman, Aston Martin's Vice President and Chief Creative Officer, the fellow who has designed every Aston from the past 15 years, that Marek. Anyway, before the DBX came out he told me any SUV he designed would be unmistakably an Aston Martin.
I think he nailed it. The gaping Aston Martin grille is unmistakably the same as the DB11's and the tailgate, which although is the back hatch to a large SUV, is absolutely the same as the rear end of the Vantage.
Everything in between has all the family hallmarks. There are those oval headlights and the huge beak of a bonnet, the chiselled side panels with wheel arches that push up towards the sky and those rear haunches.
Not a fan of minimalist design? Then you'll love the DBX's cabin and its dashboard cluttered with dials, buttons, and switches.
It's like the cockpit of a plane and it's a very Aston Martin thing – just look at the layout of the DB5 from the 1960s, it's a mess, a beautiful mess though. The same goes for current models such as the DB11, DBS and Vantage.
Seriously, if there was one area where Marek may have decided not to make the DBX unmistakably Aston Martin, I wish it had been the interior.
Still, I think the DBX has the best cabin design of any current Aston, with its large media screen built into the centre console and more modern styling.
But regardless of what it looks like the feel of the materials is outstanding. There's a thick leather coating on just about every surface, apart from those which are solid, cold metal, like the paddle shifters and door handles.
It's a plush, sporty place, like Batman's suit only it smells a lot nicer.
The DBX is a large SUV at 5039mm long, 2220mm wide with the mirrors unfurled and 1680mm tall. Yep, this thing fills up an entire space in a car park.
The DBX comes in a choice of 53 colours. Yes, fifty three. There's the 'Onyx Black' my test car wore, but also 'Royal Indigo', 'Supernova Red' and 'Kermit Green.'
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.
Until the DBX came along the most practical Aston Martin was the five-door, four-seater Rapide which had a huge rear hatch and a boot big enough to swallow an entire matching five-piece luggage set – I saw it with my very own eyes.
Now there's the DBX which seats five (well, four comfortably, because nobody wants to be in the middle) and has a boot with a luggage capacity of 491 litres under the leather cargo cover.
As you can see it fit our three-piece CarsGuide luggage set, and I also used it to pick up some compost – very likely the first time anybody has done this to a DBX ever in Australia, and probably the last.
Cabin storage is impressive. The floating centre console is suspended like a hammock and under it is a huge bunk for a phone, wallet, and small bags. The split-opening armrest houses a large box, too.
The door pockets are on the small side but there are two cupholders up front and another two in the fold-down armrest in the second row.
Talking of rows, there's no third row. The DBX comes as a two-row, five-seater only.
It’s a roomy second row, with more than enough space for me at 191cm (6'3") tall to sit behind my driving position and headroom is excellent, too.
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.
There is only one type of Aston Martin DBX and it wears a list price of $357,000, so it resides in the price range above the Porsche Cayenne, which tops out at $336,100, but below the Lamborghini Urus, which starts at $390,000.
The Bentley Bentayga V8 is its closest price rival, starting less than $10K higher than the DBX.
And while we're marvelling at the emergence of these super SUVs don't discount the original luxury SUV brand. The Range Rover SV Autobiography Dynamic is $351,086, and superb.
Let's take a look at the Aston Martin DBX's features.
Coming standard is leather upholstery, heated front and rear seats, three-zone climate control, a 10.25-inch media display with sat nav, Apple CarPlay and digital radio, a 12.3-inch digital instrument cluster, a panoramic glass sunroof, power tailgate, proximity key with push-button start, LED headlights and tail-lights, and 22-inch forged alloy wheels.
For this high-end corner of the market the value is good, but there are a couple of misses such as the lack of a head-up display and Android Auto isn't supported.
But if you wanted a shopping trolley packed with value you'd go to a supermarket, right? Maybe. What you really want to know is what it's like to drive, right? Let's start with horsepower.
The XM is one of those 'no options' vehicles. That is, you pay the basic price, you get one with the lot. The aged leather and even the optional 23-inch wheels and tyres are no-cost options, so it’s clear where BMW is aiming the thing.
As well as the plug-in driveline, all-wheel drive and all the M driving focus, the XM features plenty of tech including massaging front seats, heated seats all around, a high-end stereo, heated and cooled cupholders, four-zone climate-control, wireless phone charging and twin, curved info screens for the driver measuring 12.3 and 14.9 inches. The novel roof lining also features 100 pin-point LEDs for effect.
The cost of such detailing is a not insubstantial $302,200. That figure does, however, undercut two of its main rivals, the Lamborghini Urus ($395,888) and the Aston Martin DBX ($356,512).
It’s also worth mentioning that the XM is not even BMW Australia’s most expensive model; in fact, it’s fourth on the ladder.
When it came to giving the DBX an engine Aston Martin chose the same 4.0-litre twin-turbo V8 that's in the Vantage only they made it more powerful – 25kW more at 405kW (542hp). There's 15Nm more torque as well, at 700Nm.
Shifting through a nine-speed automatic transmission the DBX's 0-100km/h time is 4.5 seconds, which is almost a second slower than the Vantage's 3.6 seconds.
That said, the DBX weighs more than 2.2 tonnes, has a maximum ground clearance of 190mm, can wade rivers to a depth of 500mm and has a braked towing capacity of 2700kg. Oh yeah, and it's all-wheel drive.
That engine is one of the world's best V8s. It's light, compact, efficient and can produce enormous grunt. It's also made by Mercedes-Benz. Yup, it's the same (M177) 4.0-litre V8 found in the Mercedes-AMG C 63 S and a stack of other AMG-badged beasties.
There's just one thing, the V8 in the DBX doesn't sound as good to me as the one in a Mercedes-AMG. Aston's version has a less guttural and breathy exhaust note.
Sure, it still sounds amazing and when pushed hard it screams like Boudica charging into battle, but how often will you drive like that?
Most of the time we're in traffic in the suburbs and city trundling around at 40km/h. But even with the ‘loud’ exhaust mode set the note is still not as deep and brash as the AMG, which sounds delicious even at a standstill.
You probably already know why Aston Martin uses Mercedes-Benz engines. But just in case, it's because the brand with the star has been a part owner since 2013. Aston saves money and in return gets some of the best engines in the world.
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.
In my fuel test of the DBX I took in open roads and city streets and measured 20.4L/100km at the pump.
On the same test loop the Urus I drove used 15.7L/100km and the Bentley Bentayga consumed 21.1L/100km.
It's not surprising these super SUVs are thirsty, but if you're spending all your time on city roads you can expect the consumption to be even higher.
What is surprising is Aston Martin thinking anyone could really get 12.2L/100km, but then all carmakers tend to claim overly ambitious fuel economy figures.
Just think, your next car after this will probably be electric, so enjoy the petrol while it lasts.
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.
The DBX is a circa 550 horsepower giant that can reach out and almost touch 300km/h. But testing it on Sydney's roads is like having a champion racehorse in your backyard and your neighbour asking you what it's like to ride.
A racetrack wasn't handy at the time and I'd signed a form saying I'd not put any more than 400km on the clock during its stay with me, which meant having to choose my test loop carefully.
Fortunately, this was before Sydney was plunged into the current COVID lockdown, which makes that 400km now seem vast.
First, the DBX is an SUV anybody could drive, every day. Visibility is great and the ride is fine considering it rolls on 22-inch wheels and wears rubber as wide as some doorways and as thin as my socks (285/40 front and 325/35 rear Pirelli Scorpion Zero). Power delivery is smooth and predictable.
I did drive it every day, doing the shopping, school pick ups, a trip to the garden centre to fill it with plants and (ahem) compost, and it performed exactly as a large SUV should.
A source of frustration was the location of the shifting buttons high on the dashboard. Have a look at the images. Even with my chimpanzee-like long arms I had to stretch to change from Drive to Reverse. And with a not so small turning circle of 12.4m, three-point turns were a bit of an arm workout.
But the bigger frustration was the driver-car connection which didn't feel quite right. A good car-driver connection is essential for any great performance car.
Yes, there wasn't a race circuit where I could get to know the DBX quickly. But a good road, driven often with test cars, reveals a lot, too.
And the DBX didn't feel as good as the Lamborghini Urus, which is not only more comfortable but feels more dynamic and offers a superb connection between the driver and the machine.
The DBX is fast, it's powerful, the huge brakes pull it up quickly (almost violently so, if required) and handling is incredibly good.
It's just that I didn't really feel a part of it much at all. You know, the whole driver and car becoming one, thing. I felt like the third wheel on a date.
That connected feeling has been mastered by Porsche with its SUVs, but I feel the DBX needs more work. It felt unfinished.
I was told at the start that the DBX I was testing was a pre-production vehicle, but I'm sure that doesn't cover the shortcomings in the way it drove.
It's disappointing. I was hoping for better, but I think further development will see that come later.
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.
The DBX hasn't been given an ANCAP crash safety rating and it's unlikely it ever will, which is often the case with low-volume, high-end models.
Still, the DBX comes standard with seven airbags, AEB, lane keeping assistance with lane-change warning, rear cross-traffic alert, blind-spot warning, traffic sign recognition, auto parking and adaptive cruise control.
For child seats there are three top tether anchor points and two ISOFIX mounts across the second row.
I found it easy and quick to fasten my son’s car seat into the DBX.
As well as the usual passive safety features, the XM also hides the latest active safety gear. In fact, BMW reckons the XM has more driver assistance than any other M car before it.
Those elements start with the 'Driver Assistant Professional' which bundles active cruise-control with stop-go ability, steering and lane-keeping control, automatic speed limit assist and active navigation.
Parking assistance is also featured which incorporates a reversing assistance function, front, rear and panoramic camera views with a 3D view built in.
BMW’s 'ConnectedDrive' includes an emergency call function in the event of a crash or other emergency.
No ANCAP assessment so far.
The DBX is covered by Aston Martin's three-year-unlimited kilometre warranty. Also included is roadside assistance.
Service intervals are every 12 months or 16,000km.
Aston Martin doesn't have have capped price servicing for the DBX nor can owners purchase a maintenance plan for the SUV.
We asked Aston Martin for an estimate of how much owners can expect to pay for servicing over the life of the warranty, but a spokesperson told us, "We are unable to provide an estimate on the cost of servicing over three years."
With Aston Martin unable or unwilling to give us any guidance on servicing costs, maybe there are recent model Aston owners out there who can. Let us know in the comments section below.
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.
