BMW IX3 vs Aston Martin Vanquish

What's the difference?

The BMW iX3 is a rarity in the market, a premium-feeling electric model that's not a whole lot dearer than petrol alternatives.

For those happy to trade some of the Tesla Model 3 and Kia EV6 GT's all-paw performance for a luxurious cabin, slick drive and badge cachet, the iX3 M Sport is a very attractive package. Until Audi's Q4 and Q6 e-tron arrive, the iX3 remains basically peerless in this part of the market.

No wonder, then, that BMW is Australia's third most popular electric car brand after Tesla and BYD. The vehicles capture everything the brand promises at a price that looks good on paper and better in the real world.

The definition of luxury is having something you want, rather than something you need. And the Vanquish is definitely something you don’t need, but will desperately want once you’ve experienced it. It’s opulence on wheels, the kind of car you buy mostly because you can. Because owning a V8-powered Aston Martin wouldn’t cut it in your circle of friends. Or because you just want the very best things in life, cost be damned.

Now that we've seen the new X3, the current model is already dated. Not that it was a cutting-edge design at launch but there is precious little offensive about this mid-size SUV.

Fussy wheel designs, strange closed in grilles and clashing blue accents aside the iX3 M Sport remains a plenty handsome option as you approach.

Inside the cabin's shapes feel positively conservative next to BMW's latest efforts like the X2 and 7 Series but, in a way, this is no bad thing.

It's also nice that you can tailor this car's appearance to your liking without spending extra, the combination here rocks a nice blue paint with tasteful brown upholstery for a classy look.

You can have Oyster white leather or simple black and the paint colour palette is refined without being restrictive.

While the engine is the unique heart of the Vanquish, the design is the first element that grabs your attention. Even for a brand renowned for its GT cars with imposingly long bonnets, the Vanquish stands out.

That’s because the designers deliberately added 80mm of space between the front axle and the A-pillar (the front windscreen pillar) to elongate the bonnet even more for what it calls a “rakish and indulgent” profile. 

The lines flow across the length of the Vanquish, from its trademark grille to its Kamm Tail, giving it a look that is somehow simultaneously classically Aston Martin - with elements of its multiple generations of GT cars - while also being contemporary. 

Some of the modern touches are derived from Formula One, as the brand looks to leverage its racing team, with bonnet louvres to help cool the engine without unsettling the air-flow too much.

Aston Martin’s Chief Creative Officer Marek Reichman calls the Vanquish “an iconic halo model” and explained the design was deliberately pushing “beyond the expected, rational, and thoughtful.” Which sums up this dramatic piece of automotive art quite nicely.

The BMW X3 was developed with family buyers in mind and that has paid dividends because it has an extremely practical cabin with lots of thoughtful storage.

Each of the four doors has a bottle holder and generously-sized pocked for extra storage. There are two cup-holders in the centre with a wireless charging pad, secure spot for the key fob and USB port in easy reach. You can slide a roller cover down to hide valuables.

Key driving controls are smartly grouped together around the iX3's unconventional gear selector. Here, you'll find the start/stop button along with hard switches for drive mode selection, stability control and exterior cameras.

Right next door is where the rotary 'iDrive' controller lives with yet more physical shortcut buttons. Including the extra option to easily interact with the multimedia system on the move is a refreshing delight that you don't see in so many touchscreen-heavy EVs. There's also a physical stack for HVAC and seat heating controls.

The 12.3-inch touchscreen is responsive and bright with BMW's slightly older system having a more conventional appearance than the latest software in the iX2. Apple CarPlay and Android Auto are wireless and still work flawlessly.

If there are some negatives, they would be some build-quality niggles. On the whole the materials are high quality and the car is well screwed together but the indicator stalks feel decidedly flimsy compared to BMWs of old and I noticed a rattle from the parcel shelf on the road.

The eight-way power adjust seats with tilt and under-leg extension are classic BMW, being sporty enough to hold you in but with enough padding to stay comfy. Though we will knock this car down for lacking power lumbar adjust.

Those in the back will be plenty comfortable even if they're taller than 180cm with ample head, leg and toe-room. There doesn't appear to be a major compromise to the floor height despite BMW stacking 10 lithium-ion modules beneath.

Vision out is excellent with an expansive glasshouse and full-length sunroof.

Amenities include two USB-C charge points, a third climate zone, fold-out armrest with pop-up cup holders and generous storage in the doors.

Fitting child seats should be pretty simple with doors that open wide, two sets of ISOFIX ports (that you can't lose the covers of) and three prominent top tether anchors in the recline-adjustable backrest.

The boot is large with 510L of space at a minimum that expands to 1560L if you fold the 40/20/40 split backrest flat. There's a sense of solidity in that process, too, with sturdy levers and components.

So sturdy that the retractable luggage cover is quite difficult to remove, especially for shorter owners. Other niceties include a single shopping bag hook, LED lighting and 12-volt socket in the back.

No BMW X3 comes with a spare tyre so that should come as no surprise. The iX3 instead has a tyre repair kit. There is underfloor storage in the iX3, though, which is the perfect place to store both charging cables — Mode 2 and 3 — that are included.

Despite measuring nearly five metres long, the Vanquish is a surprisingly small car from a practicality perspective. Because the added wheelbase is ahead of the cabin, it remains strictly a two-seater, with no room for rear passengers.

There’s limited small item storage, too, aside from a couple of cupholders and a lidded console box. Although, on the plus side, the lack of rear seats creates room for some small shelves in case you need to store some loose items.  

It also has a surprisingly small 248-litre boot, which means limited storage for anything, including luggage, for a road trip in what would otherwise be a great road trip car.

As for the multimedia system, while not at the cutting edge (although Aston Martin will debut Apple CarPlay Ultra in its DBX model) the system works well for this type of car.

It’s unlikely too many under 25s will be grabbing this $700K luxury GT, so the fact the media system has a touchscreen and an array of physical buttons is a welcome detail.

As for the 1170-watt, 15-speaker Bowers & Wilkins sound system, it performs incredibly well, as you would probably expect. Like the car it has loads of power but excellent attention-to-detail with fantastic clarity, too.

The Vanquish sits at the top of the range for now, at least until the new Valhalla supercar arrives in Australia, and has an eye-watering starting price of $737,000.

Not only does that not include on-road costs, which will likely push the price closer to seven-figures, there’s also the plethora of options and customisation you can choose from that will add to the amount you pay.

Not that the standard specification is bad. For $700K you do get 21-inch alloy wheels, carbon ceramic brakes, 16-way adjustable sports seats, keyless ignition, a 10.2-inch touchscreen multimedia display, Apple CarPlay, Bluetooth, wireless phone charging and a 1170-watt 15-speaker Bowers & Wilkins sound system.

Of course, on top of all that you get a bespoke chassis and a unique twin-turbo V12 engine, that puts the Vanquish in the same class as the Ferrari 12Cilindri, which starts at $803,500 - making the Aston Martin look competitive. 

In this case there isn't much under the bonnet except for electric gubbins. The single electric motor – that uses no rare earth materials – resides at the back and generates 210kW/400Nm.

Those outputs are fairly close to a petrol X3 30i, though of course this model is rear-drive only.

Thanks to the rapid response of electric motors, the iX3 M Sport can sprint from 0-100km/h in 6.8 seconds (claimed).

BMW has chosen to give the iX3 a long-travel progressive throttle pedal that makes grunt easy to meter out. However, the regenerative braking could do with a little more refinement.

There are two settings, 'D' — just like letting off the throttle in a combustion car — and 'B' which is quite strong. The blending between regenerative and physical caliper-on-rotor braking is vague, though, which can make low-speed moves a bit jerky.

The engine is undoubtedly the star attraction of the Vanquish, with the twin-turbo 5.2-litre V12 being the last of its kind in the British brand’s line-up now that the DB12 has switched to an AMG-sourced twin-turbo V8. 

While that engine is arguably better with its excellent performance, smaller dimensions and lighter weight, the fact remains that for many of Aston Martin’s long-time buyers, it’s V12 or nothing.

It also helps that the V12 produces an extremely potent 614kW and 1000Nm, which is way ahead of the 611kW/678Nm the Ferrari 12Cilindri makes. So you get bragging rights at the golf club with your Ferrari mates.

The engine features a unique titanium exhaust and is paired with an eight-speed automatic transaxle that drives the rear wheels.

That is enough to propel the Vanquish to a top speed of 345km/h, making it the fastest production car the brand has ever produced, with a 3.3 second 0-100km/h time.

The iX3 M Sport's WLTP rating is a respectable but not groundbreaking 461km on the combined cycle. The reality is a little bleaker, our test car displaying 316km on its digital instruments at 100 per cent charge.

Going against what you might expect for an electric car, the iX3 was not very efficient in town, we initially saw 24kWh/100km on the read-out which is quite high.

It is better suited to a longer, steady-state run. Our regular 200km country and suburban test loop dropped the consumption to 18kWh/100km for a real-world driving range of 411km.

When it's time to bring the charge levels back up the iX3 will take on AC electricity at 11kW, for flat to full in seven and a half hours.

Public fast-charging caps out at 150kW (DC) though averages to 104kW over a 10-80 per cent session. This should take 21 minutes, says BMW.

We only observed a maximum of 101kW on a DC charger though the pylon did not appear to be performing at full energy with other vehicles having similar issues.

To say the Vanquish isn’t the most fuel frugal vehicle on the market is an obvious statement, but even its claimed 13.7L/100km is best described as optimistic.

That’s not surprising given its size and performance, but with an 82-litre fuel tank that’s a driving range of less than 600km, at best.

In the real world, during our time in the Vanquish, the car’s trip computer was indicating that we stayed in the high teens; although that featured limited freeway/extra-urban driving.

Despite no saucy straight-six, V8 or twin-cam four-cylinder there is an inherent 'BMW-ness' in the iX3 M Sport. The way it steers, accelerates and rides all match the brand's DNA.

It is not a plush SUV, with some firmness to the suspension even in Comfort mode on the adaptive dampers — this may have something to do with BMW's 40PSI front and 45PSI rear tyre pressure recommendations — but without ever being crashy.

Build up a little more speed, beyond 60km/h for example, and the body settles nicely with a solid, assured stance.

There's no evidence of suspension noise and road noise is very well insulated as well, even without the up-spec M Sport Pro's acoustically insulated glass. 

The steering is light in Comfort mode which makes it ideal for urban driving. It also has three turns lock-to-lock which is a lot for a sporty-ish BMW, however that is largely down to the improved steering angle. Without an engine or AWD system, the iX3 has a great turning circle of just 12.1 metres.

Moving things up a notch into Sport adds extra weight to the steering which helps judge the grip on good roads, which is pretty decent from the 245/45R19 Yokohama Advan Sport V107 tyres.

When you approach the limit, the iX3 is very secure but significant mid-corner bumps can unsettle the car, bringing its 2180kg tare weight (a 325kg penalty over the xDrive20i) sharply into focus. Pull it back a touch, though, and the iX3 M Sport is plenty rewarding on a country road.

Mostly, the iX3 is a refreshingly natural electric car out on the road. You could put anyone in the driver's seat and they'd be smooth just like in a combustion car.

As cars go, few can match what the Vanquish offers. Even in my 20+ years of driving every type of car imaginable, the Vanquish stands out as being something distinct, bold and special.

Sitting behind the wheel, the bonnet looks like it stretches out to the horizon and you feel like you’re sitting on the back axle of the car. And yet, when you start driving, the Vanquish feels like it shrinks around you.

At normal speeds it feels like a classic grand tourer, relaxed, refined and easy to drive. Obviously it's a firmer ride than your average luxury car, but that’s a small price to pay for the breadth of capability this car offers. 

Because once you get out of the urban environment, the Vanquish becomes something else entirely. On a winding road this British beast is surprisingly agile for such a big car.

The steering feels direct and the front end responds with much more precision and poise than you should reasonably expect from a car with such an exaggerated bonnet.

No, it doesn’t have the dynamic aggression the more compact Vantage offers, but it manages to take elements of that car and combine it with the GT nature of the DB12 to give you the best of both Aston Martin’s coupes.

Of course, the catch is it’s much too fast for Australian roads and isn’t really designed to be a track day car, so in Australia - without autobahns or more liberal views on speeding - the Vanquish in many respects doesn’t make sense.

But that is arguably its driving essence, you buy it because you know what it’s capable of, even if you’ll rarely use it, and that is an absolute luxury.

There’s no ANCAP rating given the extreme low-volume nature of the Vanquish. However, it does come with complete airbag coverage for both occupants and a laundry list of safety acronyms.

These include autonomous emergency braking (AEB), forward collision warning (FCW), adaptive cruise control (ACC), traffic sign recognition (TSR), lane keep assist (LKA), lane departure warning (LDW), blind spot assist (BSA) and rear cross-traffic assist (RCTA).

In addition there’s driver attention assist, to make sure you stay alert in such an expensive machine, and door exit assist, so you don’t open the long doors into a passing car or cyclist.

Importantly, none of these systems are intrusive or annoying, so credit to Aston Martin for integrating them smoothly.

The iX3 M Sport is now covered by a five-year/unlimited kilometre warranty in Australia.

Servicing is due on a conditional basis with the multimedia system prompting the owner when to visit a dealer.

BMW offers serviced packages for electric vehicles that last six years/unlimited kilometres, with the iX3's pack costing a reasonable $2325 over that time.

Despite the extraordinary price tag the Vanquish is covered by a very standard three-year/unlimited kilometre warranty. It’s a surprising, and some might argue disappointing, short period of coverage for a car that is not only expensive but should have a long life.

However, it does redeem itself in some way by including the first five years of servicing into the cost of the car. Ferrari offers seven for its models, so Aston Martin is still behind the market, but included servicing feels right for a car costing nearly $1 million once you put it in traffic.
