Porsche 911 vs BMW i Series

What's the difference?

The more things change, the more they stay the same. The t-hybrid might be an entirely new propulsion system for the 911, but the net result is unchanged – power, poise and performance on tap.

The thing that really grabs you from behind the wheel of a car like this is just how far EVs have come. The fact you can get a ridiculous range and have a really, really good time on the right twisting road is a pretty good deal and solidifies the fact EVs like this one are the future.

This facelift debuts a revolutionary exterior design that has completely reshaped the 911.

Just kidding. If it ain’t broke and all that. The front air vents and exhaust have changed, the former now an active intake system that deploys via vertical flaps, but elsewhere it’s largely evolution over revolution.

Instead, Porsche has focused most of the updates in then cabin. In here, you’ll find a new digital instrument panel, they’ve changed some of the levers and the steering wheel.

In true Porsche fashion, though, this new 911 mimics the older versions in that it's one of the more intuitive cabins you’ll ever sit in. Everything feels as though it’s exactly where it should be, and all feels entirely centred on the driver.

It's hard to talk about the design of the BMW iX3 without spending some time at the front end. This is a bold, bold take on a BMW grille, and one that is entirely devoid of chrome or metallic lashings.

That’s not to say it’s boring. The iX3 has a light theme that runs inside and outside, the latter of which is called the Iconic Glow exterior package, which replaces the physical embellishments with white lighting that frames the kidney grille and the other inserts. It looks very cool and very modern.

In the cabin, the lighting theme continues, this time under the dash inserts that illuminate from within. But that’s not what really draws your eye.

That honour goes to the Panoramic Vision, which replaces the traditional driver’s screen with a pillar-to-pillar display that stretches the width of the cabin and displays all your key driving info.  It seems like a strange thing to get your head around but it felt natural almost immediately, with everything you might need (including a g-meter in its sportiest mode) on display.

Also new is the funky and chunky BMW steering wheel, which reminds me a little of one of those double-sided lizards, in that it can be hard at times to figure out which way is up, and which features 'Shy Tech' (features and controls stay out of sight until the driver or passenger needs them).

All in all, I like the space. There are just enough traditional-feeling elements mixed with new tech to make it feel futuristic and familiar.

This probably falls under the ‘next question, please’ umbrella, given that, while the Porsche 911 is known for a lot of things, vast acres of space with loads of practicality perks just ain’t a part of its portfolio.

The new 911 measures a not-insubstantial 4533mm in length, 1852mm width and around 1294mm in height, and it rides on a 2450mm wheelbase. Luggage space is a paltry 135 litres under the bonnet, plus whatever else you can fit in your pockets.

There’s seating for four, should you not like the people you’re squeezing back there very much, but really the 911 is best enjoyed as a two-seat proposition – which is why you can also delete the backseat, should you wish.

It also weighs a minimum 1595kg, or up to 1745kg, but Porsche says the hybrid tech only adds about 50kg to the total kerb weight.

The BMW iX3 is 4782mm in length, 1895mm in width, 1635mm in height and it rides on a 2897mm wheelbase.

It doesn't feel huge, but there's certainly enough space in the back seat for me. At 175 centimetres I have enough knee and headroom sitting behind my own driving position, plus you can adjust the angles of the rear backrest to get a little more comfy.

But while the front seat feels very modern, the rear is more a traditional back seat experience. Back seat riders get their own air vents and temperature controls, twin USB-C charge ports and a pull-down divider with twin cupholders, but that's about it.

The auto-opening boot reveals a 520-litre luggage space (1750 with the seats folded), all of which is unencumbered by charging cables and the like, which are housed in the 58-litre frunk.

Towing and electric vehicles are never the greatest of matches, such is the drain on the battery, but the iX3 can be fitted with a standard tow ball, unlocking a braked trailer capacity of 2000kg.

There are two iX3 options for now. Or at least there will be when the 40 model joins this 50 xDrive in a couple of months. Happily, aside from the smaller battery and single motor in the 40, the feature list is identical.

In terms of pure spec, the 50 xDrive gets a lot. It’s only colours, interiors and alloys to choose as extras. 

The tech is the highlight, though. There’s a big, crisp central screen, with wireless Apple CarPlay and Android Auto, but the showpiece is what BMW calls its Panoramic Vision, which swaps the traditional driver’s screen and gauges for a vast display that stretches the entire width of the cabin.

What cost for all that, you ask? Probably less than you think. The 50 xDrive is $109,900, before on-road costs, and for that you get a massive drive battery, lots of range and plenty of dual-motor punch. But the bang-for-buck bargain will be the incoming 40 eDrive, which will arrive at a LCT-busting $89,900, MSRP.

A new (or at least, massively altered) 3.6-litre petrol engine has been developed for this T-Hybrid, which combines with two electric motors to produce a total 398kW and 610Nm. It’s only available with Porsche’s very good eight-speed Porsche Doppelkupplung (PDK) automatic, largely because the brand admits it would be… well… unpleasant to drive as a manual.

Now, there is lots of magic at work here, and I don’t want to bore you, but the Porsche setup sees a lightweight 1.9kWh battery placed basically in the middle of the front axle, and a 12-volt battery now behind the front seat. Then, a tiny e-motor lives as part of the gearbox (it’s just 55mm long) and delivers up to 150Nm at low speeds to supplement the petrol engine.

It’s joined by what Porsche calls an “electric exhaust gas turbocharger”, which essentially removes the spooling time from the turbo, delivering instant power.

The aim of the game here is excitement, not efficiency, and the launch-control-aided spring to 100km/h takes just 3.0 seconds. And it somehow feels, and sounds, faster.

The latter being important, with Porsche aware that if the new powertrain didn’t sound good, "nobody would like it”.

We’ll focus on the 50 xDrive, as that’s the one we’ve driven, and because the powertrain is a peach. Its twin-motor all-wheel drive set-up delivers a total 345kW and 645Nm, which is a lot. And because there is no traditional transmission to step through, and because all that oomph arrives at once, it feels plenty punchy indeed.

BMW says the sprint to 100km/h takes 4.9 seconds, and we believe them. Top speed is a claimed 210km/h.

Porsche in Australia is yet to lock in local fuel use for the Carrera GTS T-Hybrid, but international testing has it at 10.5-10.7L/100km, C02 emissions of between 239-244g/km. 

Those aren’t exactly Toyota Prius numbers. But again, that was never Porsche’s intention. The electric power on offer here is intended to improve acceleration, not fuel use.

It’s fitted with a 63-litre fuel tank, which should deliver a driving range of around 600km per tank.

As we mentioned at the top of this review, this is another big plus for the iX3. Its massive 108.7kWh net NMC battery delivers a maximum driving range of 805km, which is frankly ridiculous. To get it, you need to engage Efficiency Max, which dulls the drive experience, but that is an impressive number all the same. Engage the sportier settings and the figure drops to more like 650km-plus. 

Charging is 22kW AC and an impressive 400kW DC – or 300kW in the upcoming 40 model — which means a 10 to 80 per cent charge in 21 minutes when plugged into the fastest of chargers.

BMW says to expect 15.1-17.1kWh/100km in terms of energy usage on the WLTP cycle.

Porsche did just about the Porschiest thing to ever Porsche in launching the 911 Carrera GTS T-Hybrid, in that we piled into cars in Melbourne, drove the many, many hours (well, it feels that long, at least) to the Phillip Island race circuit, beat the hell out of the cars on track and on the drag strip for several hours, then trundled back out on the road and drove them back to Melbourne.

The subliminal messaging here is pretty clear. This new 911 might have a new powertrain, but it can still deliver the road-track-road experience without breaking a sweat — or, more importantly, without breaking any expensive bits.

So let’s do this in order, shall we? On the road, this new 911 is every bit as sweet as it has ever been. Comfortable, quiet enough when you want it to be, and — save some road noise from those big wheels – quiet enough to let you forget you're driving something with one of Peter Dutton’s nuclear reactors hidden beneath its svelte metal work.

Mind you, that T-Hybrid powertrain will happily remind you of its presence every time you press the accelerator in anger, the exhaust erupting into life and the 911 genuinely rocketing into the future, but stay gentle with your inputs and this hybrid 911 is a genuinely comfortable, genuinely liveable daily driver.

Its split personality appears when you rumble out onto a race track though, where you quickly discover the electrified, and electrifying, Porsche is properly, properly rapid, both in a straight line or around Phillip Island’s fast and flowing circuit.

It’s so rapid, in fact, that it feels most closely related to a performance EV, like the Taycan. Of course it is louder and more engaging, but that’s the best way I can think of to describe the instant power on offer here. There’s no ICE-like lags or lumps in the way that 398kW and 610Nm finds its way to the tyres and into the tarmac. Instead it’s just this constant, savage flow of power that never seems to let up.

Porsche says this new powertrain is about 50kg heavier, but you’d need to be plugged into the race track like its the Matrix to ever feel it, with the T-Hybrid feeling lithe, grippy and athletic, aided by near-perfect steering, the best automatic gearbox in existence, and exactly zero roll through the body. In fact, the only thing that really moves when cornering hard in this new 911 is the driver, and I genuinely got out after several laps with a sore neck from trying to stay vertical.

Downsides? Well, it’s faster in a straight line (it will be some 7.0m further down the road after 2.5sec when compared to the older GTS) and faster around corners (8.7sec faster around the Nurburgring than its predecessor), but there’s something delightfully analogue about the outgoing car, which also manages to feel more aggressive under heavy acceleration, too, owing to the little ebbs and flows of power, and after driving both back-to-back, I still can’t decide which one I like more.

BMW spent a lot of time describing this car as being of revolutionary importance to the brand. It was designed as an EV from its inception, but is also the flag bearer for the New Class gen of cars, and so it has all sorts of features and tech that will roll out across the rest of the BMW range.

Does it feel overly revolutionary from behind the wheel? Not really. I mean, it drives forwards and backwards, and turns around corners when you move the wheel, all of which is to be expected.

But it does mostly feel very BMW, which I think is what they meant. The Jekyll-Hyde nature of the iX3 becomes apparent the moment you engage its sportiest driving modes and flatten your foot. This is proper push-you-back-in-your-seat acceleration that feels slightly more violent than the iX3's claimed zero-to-100km/h time suggests.

Then there's the flip side of that coin. Engage Efficiency Max and you can seemingly drive forever (or at least more than 800km), sipping battery juice and riding in peace, quiet and comfort. 

But at its core, and no matter the drive mode, it feels like a BMW. Crucial to that is a thing the brand calls the Heart of Joy, which sounds utterly sci-fi but really is a computer brain that works on traction and power to make sure you never lose grip.

If you've ever been in a car where the traction control light is flashing on a dash, you'll know what usually happens is it cuts engine power until you find grip, and it gives you power again, then cuts it, then gives it to you as required to find the grip, and it can give you that kind of jerky, stop-starty kind of feeling.

The iX3 doesn't do that. Instead, it plays with traction and is far more subtle without ever cutting power, and gives you the feeling of being able to tip into a corner and then power out without ever feeling like you're going to lose grip, or power.

The bigger electric motor is at the rear axle, which delivers most of your performance unless you need extra grip. So, when you are powering out of a bend, it feels a lot like a rear-wheel drive car and really well sorted from behind the wheel.

If that's the driver's side of the equation, the other side of it is pretty good, too. We took to the town at city speeds, and it was super comfortable, quiet and absorbed most of the road imperfections pretty easily.

Interestingly, the suspension isn't high-tech. There's nothing adaptive about it, and there's no air cushioning or anything like that. But it feels well tuned, and is pretty comfortable, even on dodgier road surfaces, while still delivering a sense of connection.

My favorite kind of mid-size SUVs are ones that have that dual nature. Something that has space for the family and all of their things, but also something that can be a fair bit of fun on the right twisting road, and this one absolutely nails that brief. It is a hoot to drive on twisty stuff. 

Downsides? Well, you can't entirely disguise more than two tonnes of weight. If you're going downhill, especially on a twistier road, you can feel the weight around you, especially when you go to pull up in a hurry, despite the strong-biting brakes.

The other thing is the steering, which is direct and lovely but quite light. It doesn't have that meaty heft some BMWs offer, and as a result, it can be interesting to place the vehicle. You can find yourself a bit further over in the lane, or further away from an apex than you're expecting, because your light inputs have really shifted the vehicle. 

But BMW has nailed the brief here. Do keep an eye out for the cheaper one that's coming, though. It could be a bang-for-bucks, rear-drive bargain.

The iX3 is fitted with all the active safety stuff you might imagine – things like active lane keeping, dynamic cruise control and more cameras than were used to film The Odyssey. Happily, only the driver attention monitor chirped me on my test drive, and usually when I had my head turned to the far side of the Panoramic Vision display.

It also has a self-parking function you might actually use, given how quick it is to pick a spot then park in it.

There are eight airbags and three top tethers across the rear for child seats (as well as ISOFIX anchors on the two outer positions. But the big news is that its maximum five-star rating was achieved under ANCAP’s super-strict 2026 protocols, which is something few, if any, cars on sale in Australia can claim.

The 911 Carrera GTS is covered by a pretty underwhelming three-year, unlimited-kilometre warranty, with servicing required every 12 months or 15,000kms. We don’t have the hybrid service pricing yet, but as guide, the last 911 split the services into minor and major, and charged either $785 or $1285 for each.

BMW offers a five-year, unlimited kilometre warranty, which is about right for the traditional premium players, but off the pace elsewhere. The traction battery is then covered for eight years or 160,000km.

The service intervals are condition based, rather than timed, and BMW sells a pre-paid package for the iX3 which is $1614 for four years, or $2420 for six years.

You can upgrade either to what BMW calls Service Inclusive Plus, which includes high-wear stuff like brake discs and pads and it is $5535 for four years or $6615 for six years.

There are around 50 BMW dealers across Australia covering mainly cities and key regional centres.
