Aston Martin DBX vs Range Rover Sport

What's the difference?

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.

Range Rover proudly calls it its “most dynamic” model ever, and based on our first experience that’s most definitely true. Its ability to be genuinely exciting to drive on a race track is nothing short of remarkable for a brand whose history is all about off-road prowess.

On the road it shines just as brightly, with its potent engine and state-of-the-art suspension system working in unison to make for a stunningly dynamic large and luxurious SUV. And then, if you need to cut across a field or scramble up a slippery hill, it will do that too.

Range Rover’s claims of ‘breadth of capability’ is apt but arguably an understatement. I’d stop short of calling the Sport SV the obvious class-leader in the high-end, high-performance SUV market because it’s up against some seriously impressive rivals, but the Range Rover offers a broader range of ability than any of its competitors.

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.'

Range Rover is a brand synonymous with big, imposing and off-road capable SUVs, not dynamic and sporty vehicles. But in recent years the Evoque and Velar have added a new layer of style and a sleekness to the brand’s reputation.

The latest generation Sport is still a big and imposing two-tonne SUV, but it’s also definitely sportier to look at and the SV changes only add to that.

It only takes a moment looking at it and it’s clear this is an SUV that means business. The 23-inch wheels fill out the guards, the air-suspension can lower the body to the ground and the aerodynamic package, including the front splitter, make for a purposeful look.

The carbon-fibre bonnet can be finished with the centre section exposed, showing off the weave of the fibres, which is a nice touch, although fake vents on the bonnet and front fenders are a bit disappointing.

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.

There are two stand-out features in the cabin, beyond the standard high-level of luxury you expect from a Range Rover Sport. 

The first is the SV-specific steering wheel with illuminated paddles, which feels solid in your hands. But the second is by far the most interesting, the so-called Body and Soul Seats (BASS), which Range Rover has developed in conjunction with Coventry University.

Available with either genuine leather or ‘ultra fabric’ and a 3D-print knit trim, the seats look great on the outside but it’s what’s inside them that’s special.

There are four audio transducers integrated into the seat back which can vibrate to the beat of whatever audio track you’re listening to. The system uses AI to detect the lower frequencies and then work out which beats to transmit.

This is technology used by musicians, Coldplay’s Chris Martin reportedly wears transducers integrated into a vest when he performs, but Range Rover is confident it will add to the ownership experience.

It’s certainly an interesting technology and a demonstration across different music genres highlights the way the system adapts to individual songs, but it’s hard not to feel like this is more of a gimmick than something an owner will use every day. 

If you don’t like listening to music with it, the Body and Soul Seats also work with a ‘Wellness’ setting that features six audio pieces (designed by Coventry University musicians) - calm, soothe, serene, cool, tonic and invigorate.

It’s probably what you need to help settle your heart rate after you unleash the full performance potential of the Sport SV.

In the back seat there’s none of this technology but they do feature heating and ventilation as well as power recline functions. There’s also four-zone climate control, so every occupant can be comfortable.

To be blunt, the Range Rover Sport SV is one of those vehicles that if you have to ask, you can’t afford. Particularly in this case, as the model has launched in a single specification level, the Sport SV Edition One, which is priced from $360,800, plus on-road costs.

That puts it into the same financial category as the likes of the Aston Martin DBX ($356,512), Porsche Cayenne Turbo GT Coupe ($364,700) and Lamborghini Urus ($409,744) - especially when we discuss some of the pricier options.

For that price the Sport SV Edition One comes with exclusive branding on the front splitter, centre console, treadplates and puddle lamps as well as a raft of standard features likely to carry-over to the 2025 model year version.

These include carbon-fibre badges, forged 23-inch alloy wheels, digital LED headlights, a carbon-fibre bonnet, 16-way electronically adjustable front seats, Meridian 'Signature' sound system, 13.1-inch multimedia touchscreen, Apple CarPlay and Android Auto and newly developed ‘Body and Soul Seats’ (more on those later).

But if you’re feeling really sporty, you can upgrade your Sport SV with lightweight carbon fibre wheels and carbon ceramic brakes.

These will cost you a staggering $16,130 and $13,500, respectively, but the wheels measure 23-inches and are the largest fitted to a production car (and are also Australian-made by Carbon Revolution in Geelong).

Unfortunately, for now at least, this is all a moot point because Range Rover Australia has already invited and sold all examples of the Sport SV Edition One, so you'll need to be patient and wait until at least 2025 to have the option to buy one.

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.

Sadly the wonderfully evocative supercharged V8 engine from the previous generation Range Rover Sport SVR is gone.

But, thankfully, in its place is a more powerful engine that’s exclusive to the Sport SV in the Jaguar Land Rover family.

It’s a 4.4-litre twin-turbo V8 petrol engine with mild-hybrid assistance, which is actually built by BMW and based on the same powertrain as you’ll find in the M5, albeit with some specific Range Rover elements for more off-road capability.

It’s also more powerful than the old supercharged V8, making an impressive 467kW of power and 750Nm of torque, which is a 44kW and 50Nm improvement over the old engine.

It’s paired to an eight-speed automatic transmission, again with a specific SV calibration for improved performance. 

And, of course, being a Land Rover, it’s also got a four-wheel drive system with full off-road systems as well as an active locking differential.

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.

Despite all the extra power, thanks to the mild-hybrid system it’s more fuel efficient and produces less emissions than the old 5.0-litre V8.

Still, it’s all relative, and as you’d expect from a twin-turbo V8 SUV it’s still thirsty and uses 11.7-12.5-litres per 100km, based on European specifications.

The mild hybrid system uses a crank-integrated starter generator instead of a conventional alternator, providing a boost of up to 20kW and 175Nm of electrical power when needed, with the energy captured during braking and stored in a 48-volt lithium-ion battery.

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.

Before driving the Sport SV you need to understand its highly complex suspension system that allows it to be so dynamically capable. Range Rover calls it a '6D Dynamic' system, because it can control the car left and right, up and down and corner to corner. 

To achieve this the system uses a combination of hydraulic interlinked dampers, height-adjustable air springs and pitch control, which makes it a semi-active suspension set-up similar to the set-up Formula 1 race cars used to boast. 

This allows the Sport SV to sit between 10-25mm lower than the other Sport models and with its clever suspension can actually sit flatter in the corner with less pitch and roll - which is the traditional enemy of high-riding SUVs when it comes to handling.

But the suspension is only part of the story, with the intelligent all-wheel drive, rear-wheel steering, torque vectoring and the active locking rear diff all combining to produce an SUV with incredibly impressive dynamic capability.

Put simply, there’s never been a Range Rover that deserved to be driven on a racetrack. The Sport SV changes that, and thankfully the company let us loose on the challenging Portimao circuit in Portugal to put the SV through its paces.

Range Rover management was quick to stress it doesn’t expect the Sport SV to be a race track regular for its owners, but driving it on track did highlight the extreme potential it offers. 

With such a powerful engine it should come as no surprise that the Sport SV hauled down the straight, hitting 233km/h at the end of the long front straight, but with speed still rising which suggests its 290km/h claimed top speed is accurate.

Even from those speeds and with 2560kg of SUV to slow down, with the carbon ceramic brakes it was no trouble whatsoever. Instead the braking was strong and consistent across multiple laps. 

The steering is the particular highlight, with the rear-wheel steering helping to turn the Sport SV sharper and more quickly than a big SUV like this should. 

But while it impressed on the circuit, we also experienced it on some great winding rural roads across Portugal and this is where it shone even more brightly.

This is an SUV that you’ll genuinely enjoy driving with its ability to carve through corners and blast down anything resembling straight road.

But to ensure it lives up to the Land Rover badge on the front, we also drove it off-road. Nothing too serious at first, just muddy ruts, across some water and over some rocks.

But then we were guided through a course that showed off its articulation potential, which is far greater than the average owner will ever need. 

However, to achieve this Range Rover removed the carbon-fibre front splitter, so it’s not the most off-road friendly model the brand offers.

The Sport SV comes generously equipped with safety gear, as you’d expect at this price point. There’s all the usual passive safety, including airbag coverage for all occupants, and plenty of active safety including adaptive cruise control with steering assist, remote park assist and 3D surround cameras - which are used for off-roading as well as parking.

As with the rest of the Range Rover Sport range, it has been awarded a maximum five-star rating from safety agency, ANCAP.

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.

If you’re worrying about servicing costs, you’re probably shopping at the wrong end of the market, but as with the range-topping Range Rover model the price of the car is expected to include servicing for the first five years and roadside assistance for the same period.

It’s also covered by a five-year, unlimited kilometre warranty.

As with all Range Rovers the car will tell you when it needs a service depending on driving conditions. For example, if you hit the track or go off-roading it will likely need a visit quicker than if you're just commuting to and from work.
