Summary
Porsche Cayenne
The Porsche Cayenne Turbo GT needs a better name. This is the king of Cayennes and quite possibly the ruler of all super SUVs.
Well, the Cayenne Turbo GT is the fastest SUV around the Nurburgring Nordschleife. Not just that, it has such colossal power and torque it'll be side-by-side with a Porsche 911 GT3 RS in a sprint from 0-100km/h. No, a better name for this SUV would be the Cayenne GT3.
Which is perfect for me because I'm at the point in my life where although I love full-on and noisy cars I also have a full-on and noisy family.

BMW X6
First launched in 2008, the BMW X6 created history (and a new car category) with its coupe styling on an SUV framework.
It was a polarising effort but one that opened up the SUV market for those wanting the size and presence of an SUV without compromising on the sporty styling of a smaller car.
The 2024 X6 has had a facelift and that brings a more athletic and robust kerb-side appeal that might swing a few fence sitters onto the side of liking it.

The already pleasant interior has been polished with extra customisations available on trims and accents. The technology has seen the biggest upgrade and it now features a more streamlined mild-hybrid component to the engine. It all positions the X6 well and truly within the rank of luxury.
For the last week I’ve been driving the mid-spec xDrive40i M Sport variant to see how the facelifted model holds its own against rivals, the Audi Q8 55 TFSI Dynamic Black and Mercedes-Benz GLE450 4Matic Coupe.Â

Verdict
Porsche Cayenne8.1/10
Of all the super SUVs I've piloted, the Porsche Cayenne Turbo GT is the best all-rounder in terms of performance, comfort, cabin technology and style.
As a family car it's roomy, practical and easy to use and drive daily.
As a performance car the Turbo GT is stupidly quick, with the agility of a sports car. Sure, a 911 would leave it behind on a twisty race track, but this SUV is close to having that sportscar experience and keeping your family, as well.
BMW X68.3/10
I was not expecting to like the BMW X6 xDrive 40i M Sport as much as I do. The styling is still polarising but the facelift will throw more people towards the liking rather than disliking side of the fence. The cabin and boot are super practical and the X6 nails all the premium elements you expect at this level. It’s driving and handling are what win me over, though.
My son loves this one and doesn’t want to hand it back. My husband also noted how nice he thought the X6 was… and that’s saying something for a born and raised 'country boy'!
Design
Porsche Cayenne
This might be a personal thing but to me nearly all Porsches look better from the back than the front.
It's the wide stance and powerful haunches, the hunkered down suction-capped-to-the-road look that does it for me and the Cayenne Turbo GT, despite being an SUV, passes this important Porsche checklist item.
The GT aero kit only serves to make this SUV look more of a beast, and the gold-bronze looking satin Neodyne wheels are a Porsche theme that I've not always been a fan of, but I get the historic connection.
If only the Turbo GT could look a little less like other Cayennes from the front. This is the king of the SUV range and despite the apron and bumper already being exclusive to this model, there should be more.
Vents in the wheel arches, carbon bonnet with nostrils GT3-style perhaps? Or is that going too far? If you do want something more lairy then there's always the Urus.
The Cayenne Turbo GT's cabin is stunning in its plushness and modern surprises such as the passenger display, the hoodless instrument digital cluster, the lashings of Race-Tex upholstery everywhere. It's perfectly Porsche. High-performance meets high-end.
It's also highly practical. Let's talk about that.
BMW X6
SUV coupe styling with its raised platform and pinched bum just doesn’t do it for me usually but I like it on the new X6 model. The facelift helps the X6 appear more athletic and just plain meaner than the previous version.
The front end sees the most change with new adaptive LED headlights and a bigger 'kidney' grille. The kidneys are illuminated, which adds to its night-time presence and the extended blacked-out intake vents at the front and around the car make it look sharp as hell.
The weird prong on the side mirrors has been dropped in favour of a more seamless design (hurrah) and the 22-inch alloy wheels give total va-va-vroom sport-vibes.Â
On the interior, the dashboard has been revamped with a more pronounced shape and a curved display panel that houses the 12.3-inch digital instrument cluster and 14.8-inch multimedia system.
The air-vents now blend more into the dash but the little knobs for them might not be everyone’s cup of tea.
The ambient lighting is customisable and the quilted seats look beautiful but purists will wince on learning it’s synthetic leather, especially at this price point, but it feels and looks very nice.Â
Practicality
Porsche Cayenne
The Porsche Cayenne Turbo GT only makes one compromise on practicality and that's the removal of the middle seat in the back, which, with just two kids isn't used all the time but on average we might need it once a week for school mates and cousins.
Instead of a middle seat there is a shallow tray, which will fit a phone or in our case leaves and rocks found at the park.
So, yes, the Turbo GT is a four-seater only, but this is a spacious, large SUV with good head and legroom, wide-opening doors for easy entry and exit, and air suspension which can raise and lower the height for easy access.
Storage is excellent with enormous door pockets in the front and back and there are four cupholders.
There's a wireless phone charger in the front and two USB-C ports as well, plus two USB-C sockets in the back.
Four-zone climate control means the kids in the back can set their own temperatures. They also have heated seats.
I was disappointed to see there aren't sunshades for the rear windows - pretty vital in Australia where it feels like we're only about 50 metres away from the sun.
The Turbo GT's 576-litre boot just managed to fit our pram and a week's shopping, which is our minimum standard for living. Any more space is a bonus.
BMW X6
You know you’re in a large SUV when you slide into the X6 because the cabin has a lot of space in both rows.
But also because of the higher centre console design, you feel tucked into the car despite the higher seating position. It makes it feel far sportier than your typical SUV.Â
Even back rowers enjoy decent legroom and headroom, despite the panoramic sunroof and sloping roof design. Six-footers should be relatively comfortable in both rows but it's best to reserve the middle seat as a sometimes position for adults. The raised floor won’t allow true comfort for a longer trip.
Let’s chat luxury because there’s plenty to be had with the electric front seats and their cloud-like comfort.
The electrically-adjustable side bolsters and adjustable lumbar support makes it feel like you’re being cuddled by the seat and also hold you in place in a turn. The extendable under-thigh supports minimise leg fatigue on a longer trip.
However, the back seat is almost as comfortable as the fronts in terms of cushioning. You also sit in, rather than on top of the seats which is a nice change for an SUV.Â
Individual storage is great in both rows and up front you get a dual-opening middle console, glove box and a handy utility area that houses the cupholders and two phone pockets.
There is also a storage nook on the driver’s side that will comfortably hold a wallet.Â
In the rear you enjoy two map pockets on the front seat backs and retractable cupholders in the fold-down armrest.
The armrest houses a shallow device holder and sits at a good height. Both rows enjoy deep storage bins in each door and a large drink bottle holder.
Happily, the holder is tilted towards the user, rather than away which is what you usually see.
The boot is a great size at 580L with all seats in use. There’s a little lip that has practical metal scuff plates but otherwise the loading space is level.
The hands-free powered tailgate is welcome and the handy 40/20/40 split on the back row opens up your storage options.
You get a temporary spare tyre underneath the floor and it’s cool how the floor has a gas strut, which makes the area much easier to access.
The concertina-style cargo cover is a bit dicky to use but I like how solid it is. It could easily double as a shelf by itself.Â
Charging options are abundant with a total of two 12-volt ports, a USB-A port, three USB-C ports and a wireless charging pad to choose from throughout the car. But it is annoying to use the pad when the front cupholders are in use.
I like having hardened kickplates on the backs of the front seats because my seven-year old loves putting his feet on everything.
The higher ground clearance makes this an easy car to get in and out of but it also makes for a great view for my son. He finds the doors a little heavy to close but the massive door grab handles help!
Amenities in the rear row make it a pleasant space to be in for kids and adults alike. You have reading lights, map pockets, two storage shelves and directional air vents.
There is manual climate control in this row, too, but it feels at odds with the rest of the high tech in the car.
On that note, the updated technology looks gorgeous.
The head-up display is clear and the digital instrument panel offers plenty of customisation. It's a super handy feature to access your recent call log via the steering wheel controls and see it pop up on the instrument cluster.Â
The touchscreen multimedia system is responsive but you can also use the rotary dial to get around it. There is a stack of information in it, though, which will take a bit to get your head around. Can’t fault its graphics, it looks hot, but some users may feel flustered at first.
The system has built-in satellite navigation that features an augmented reality feature, which overlays dynamic instructions on the video feed. What makes it practical is how it can be viewed on your instrument cluster, which means more on-road focus for the driver.Â
There is wired Android Auto and wireless Apple CarPlay, with the latter being simple to connect to. You don’t have the important climate control buttons/dials up front and I find it annoying to access the multimedia screen to change climate and fan speed settings.Â
What you lack in controls there is more than made up for in the centre console. There are a lot of buttons, from the push-button starter, rotary control wheel and everything in between.
Even after a week, my mind still has a mini freeze looking at them while on the go.
Price and features
Porsche Cayenne
The Turbo GT is the king of Cayennes, so it shouldn't surprise anybody that it's also the most expensive with its list price of $364,700.
Lamborghini's Urus lists for $409,744Â Â and is the Cayenne Turbo GT's not-so-subtle Italian cousin, sharing the same platform and engine.
Both are in my mind the best performance SUVs on the planet. It just depends how conspicuous you want to be.
Then there's Bentley's V8 Bentayga which isn't blessed with the Porsche's good looks but would still be all over the Cayenne if the two happened to meet at a race track.
So, why is the GT Turbo the king of the Cayennes? What makes it better? For all the reasons you'd think - it's the fastest, most powerful, most luxurious and most equipped Cayenne in the range.
We'll get into mind-bending engine and performance specs soon, but first let me take you through the standard features on a car that's anything but standard.
Coming standard and exclusively to the Turbo GT are 22-inch 'GT Design' wheels in satin 'Neodyne' with full-colour Porsche centre caps, an active rear spoiler, Turbo GT front apron, dual titanium exhaust, rear apron with diffuser, 'SportDesign' side skirts, wheel arch extensions, a lightweight carbon roof and tinted LED HD-matrix headlights.
Inside, and also exclusive to this grade, is the 'GT Interior Package' with 'Race-Tex' upholstery throughout with 'Deep Sea Blue' stitching on the front seats and centre console and the armrests and dashboard.
There's also the 'Carbon Interior Package' which includes dashboard and door trim elements.
Race-Tex trim is applied to the 'GT Sports' steering wheel, roof lining and gearshift, too.
The adaptive active air suspension, which can lower the car by 15mm, is standard and only available on the Turbo GT, too.
The soft-close doors are standard (a cost option on lower grades), as are the stainless steel pedal covers.
The rest of the features are also found on lower grades and include the 12.65-inch digital instrument cluster, head-up display, proximity unlocking, 12.3-inch multimedia touchscreen with sat nav, wireless Apple CarPlay and Android Auto, digital radio, a 10-speaker Bose sound system, heated front seats, rear privacy glass and an auto tailgate.
Four-zone climate control is standard on the GT Turbo, too, and so are heated rear seats.
Our car had several options fitted such as the front passenger display ($2860) and the Deep Sea Blue Accent Package.
The passenger display is a crowd pleaser, but as a family car my kids felt like they were missing screens in the back seats, too. Well, in my day...
BMW X6
There are three variants for the X6 before you jump up to the performance M grade. Our test vehicle is the mid-spec xDrive40i M Sport model and will cost you $144,900 before on road costs.
That places it in the middle of its rivals and you get a well-specified model for the price tag but our test vehicle has also been fitted with a few extras, like the 'M Sport Package Pro' which adds a darkened grille and accents throughout the car, an M Sport exhaust system, red M Sport brake calipers and the M Sport signature colour stitching in the seat belts. All of that adds $2308.
Our test model also has the 'Enhancement Package' which tacks on $4616 but you get some great items like the crystal glass accents on the rotary dial and push-start button and a premium Harman Kardon surround sound system.
It also adds big 22-inch alloy wheels, a tyre pressure monitoring system and a temporary spare tyre which replaces the standard run-flat tyres on the base model.
Oh, and the 'M Brooklyn Grey Metallic' paintwork adds $1539. Just sayin’ it will cost you a pretty penny but it’s not outrageous for a luxury SUV.
Other standard equipment includes synthetic leather trims, electric front seats with heat function, electrically adjustable steering wheel, sports paddle shifters, M Sport styled scuff plates and badging, exterior puddle lamps and a full suite of LED lights including adaptive headlights.Â
You also enjoy a panoramic sunroof, adjustable lumbar support on both front seats, as well as extendable under-thigh support.
The drivers seat features two memory positions and comfort entry/exit functions (the seat and steering wheel slide back for you to get in and out of car).
For practicality, there is a hands-free powered tailgate, pre-entry climate control with programable entry time and a boot floor that features a gas strut for easy access.
We’ll touch on the tech later but the highlight is a new curved display panel that houses the 12.3-inch digital instrument screen and 14.8-inch touchscreen multimedia system.Â
Under the bonnet
Porsche Cayenne
As a middle-aged parent with two children, a Porsche that I don't have to crawl into and out of like a cubby house is a great thing.
What's even better is that this ‘easy access' Porsche is every bit as brutally powerful and fast as the quintessentially ‘pure' Porsche, the 911. Actually, it's more powerful and faster.
The Turbo GT's twin-turbo 4.0-litre V8 petrol engine makes 485kW and 850Nm with drive going through an eight-speed transmission to all four wheels.
In comparison, a Porsche 911 GT3 RS, arguably the most brutal and anti-social 911, has 386kW/485Nm.
I haven't made a mistake. Those are the real numbers. And it's only when you step on the accelerator in the Cayenne Turbo GT, and it feels like somebody's sat down on your chest, that you realise what a big deal this is.
That is such a colossal amount of oomph that this 2.2-tonne family SUV can accelerate from 0-100km/h in 3.3 seconds.
The 911 GT3 RS can do it in 3.2 and it has a roll cage and a fixed rear wing the size of a bedroom door.
And yes, we're now coming into a digital age where Teslas and other electric SUVs are quick, too, but can they go around corners like a Porsche Cayenne Turbo GT?
Do they have the same rumble and roar as a twin-turbo V8 that's terrifying and enticing at the same time.
The correct answer is, absolutely not.
BMW X6
The xDrive40i M Sport has a 3.0-litre, inline six-cylinder turbo-petrol engine with maximum outputs of 280kW and 540Nm. That’s 30kW and 90Nm up from the previous model.
It has a smooth eight-speed auto transmission and is all-wheel-drive.
The facelift sees the addition of a new mild-hybrid system which makes for almost imperceptible stop/start functionality when idling and a smidge better on-road fuel economy.Â
With a 0-100kmh sprint time of 5.4-seconds, it’s obvious that it has plenty of power to have fun with.
Efficiency
Porsche Cayenne
Seriously? This is a 2.0-tonne twin-turbo petrol V8 with a 90-litre fuel tank. Even the Porsche specs sheet doesn't understand the question because in the column for fuel efficiency there are three letters - tbc.
My own testing saw me record 22.5 L/100km at the fuel pump, which means I enjoyed driving the car very much.
A little digging around reveals Porsche globally claims the Turbo GT will use 12.6L/100km, over a combination of open and urban roads.
You might not have as much fun as I did but easing back a little might get you closer to the 700km of range this more frugal consumption figure appears to offer.
While efficient it isn't, I'm not going to mark the Turbo GT too much here because compared to its petrol rivals the fuel consumption is what I'd expect from such a high-output heavy SUV.
BMW X6
Expectations for a thirsty engine were high, considering the hefty power available, but this version of the X6 has proved to be quite economical.
The xDrive40i M Sport variant has an official combined cycle fuel economy figure of 9.3L/100km but my real-world usage averaged 8.8L/100km.
That’s after mostly open-road driving with only a little ‘city’ thrown in but I didn't hesitate to use the power, so I'm happy with the result.
The X6 has a big 83-litre fuel tank and based on my usage, you’d see a driving range of around 943km, which is great.
BMW only recommends a minimum 95 RON petrol to be used.
Driving
Porsche Cayenne
Never have I met a car this powerful and superbly athletic that is as pleasurable to drive alone on great, fast roads as it is to pilot at 50km/h in the suburbs with a family on board.
It exceeds my understanding of engineering that something this large can move so quickly. That in an instant can turn and tip into a corner with such precision and effortlessness.
Yet it can switch seamlessly and happily to coping with speed bumps and potholes, delivering a ride so comfortable it'll send babies off to sleep. And it did.
The only issue, and this is such a tiny thing, is the dash-mounted gearshift, which means having to reach up and select Drive or Reverse or Park, which, when executing a three-point turn, is necessarily frustrating.
Still, I'm giving the Turbo GT a 10 out of 10 for driving under all conditions, and we didn't even go off-road, which of course you can do, as long as it's not too wild.
BMW X6
The X6 is a thoroughbred on the road. It’s wide stance and massive wheels provide a well-balanced and grippy on-road ride experience.
Seriously, the tyres feel glued to the road even in the wet. Confidence is high with this one.
There is plenty of power to enjoy and you don’t feel like you’re digging deep for it, either, when you have to get up to speed or overtake.
It has the handling and power of a much smaller and sportier car but at no point does it feel wild or reckless to drive. It’s got a certain elegance and maturity to its handling.
Despite those massive wheels, the ride comfort is fantastic with the adaptive suspension. You still feel the road but you’re not knocked about by it. It’s very much a driver’s car in that sense but passengers still feel well-cushioned. Â
The cabin is insulated and you get basically no road noise or wind noise but occasionally you get some feedback from the tyres depending on the road surface. Longer journeys are comfortable and quiet.
The steering is light enough that you don’t feel like you’re hauling a massive SUV around but is still responsive. Meaning you can tackle a winding road or urban traffic easily.
When it comes time to park it, you’ll love having the 360-degree view camera system. It’s the best and clearest system I’ve sampled.
Add the front and rear parking sensors and no car space is an issue. But if you’re unsure, you can use the Park Assist feature to help out.   Â
Safety
Porsche Cayenne
The Porsche Cayenne Turbo GT hasn't been locally crash tested and so doesn't have an ANCAP rating.
That's quite normal for super high-end cars. But, when this third-generation model first arrived in 2017 it was tested by ANCAP's European equivalent, Euro NCAP, and was awarded the maximum five stars.
There's AEB which operates at city, urban and highway speeds, and lane keeping assistance, and lane change assistance which is a form of blind-spot warning, and adaptive cruise control. You can option rear cross-traffic alert, as well.
A space saver spare wheel is under the boot floor.
BMW X6
The X6 has an extensive safety list and I like the SOS emergency call button and front cross-traffic alert. Both are great to have but the latter is particularly useful on a large SUV like this, especially in the city or driveways.
Other standard safety equipment includes blind-spot monitoring, autonomous emergency braking, LED daytime running lights, forward collision warning, side collision warning, rear cross-traffic alert, lane keeping aids, lane departure warning, intelligent seat belt reminders, front and rear parking sensors, 360-degree view reversing camera, traffic sign recognition, driver fatigue monitor, and adaptive cruise control with stop and go functionality. As well as an SOS emergency call button and stolen vehicle tracking.
The X6 hasn’t been tested by ANCAP, so it’s unrated but it is based on the X5, which achieved a five-star rating in 2018. However, it only features six airbags which is low for a family car.
There are ISOFIX child seat mounts on the outboard seats and three top tethers in this row. Two seats will fit best but I reckon you could squeeze a third in if you had to.
There’s plenty of room for front passengers when you install a 0-4 rearward facing child seat, too, which is good.
Ownership
Porsche Cayenne
The Cayenne Turbo GT is covered by Porsche's three-year, unlimited kilometre warranty, which is lagging behind in terms of duration even compared to other luxury brands such as Mercedes-Benz, which offers five years.
Servicing is recommended annually or every 15,000km, although there isn't a capped price maintenance plan with final costs determined at the dealer level (in line with variable labour rates by state or territory).
BMW X6
The ongoing costs are surprisingly reasonable for a large luxury SUV! Like its rivals the X6 enjoys a five-year/unlimited km warranty.
However, you can pre-purchase a servicing plan for up to five years or 80,000km, whichever occurs first, for a flat $2400. Or an average of $480 per service which is inexpensive for this class.
Service intervals are also good at every 12 months or 15,000km, whichever occurs first.Â
