GWM Cannon vs Porsche Cayenne

What's the difference?

The latest version of the Cannon ute displays commendable improvement in key areas like drivetrain and chassis tuning, along with a benchmark 3500kg tow rating, heaps of standard equipment and a generous warranty for a list price well under $50K. For a tradie on a budget, it represents value that's hard to ignore.

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.

The upgraded Cannon brings refreshed exterior styling, with the front fascia featuring a new grille and bumper design, larger fog lights and more subtle use of chrome highlights.

At the rear there’s more prominent (and permanent) brand identification with bold ‘GWM’ lettering embossed on the tailgate panel, which is a welcome blast from our pick-up past.

The spacious interior design has also been enhanced with use of what GWM calls ‘premium materials’ including soft-touch surfaces on the dash and door panels along with subtle chrome accents.

There’s also a new steering wheel and the centre console has been redesigned with less buttons and dials (not always a good thing) topped by the new multimedia touchscreen.

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.

With its 2230kg kerb weight and 3225kg GVM, the Cannon Ultra has a 995kg payload rating (that’s close enough to a ‘one-tonner’ by our measure) and the latest upgrades include an increase in braked tow rating from the previous 3000kg to the class-benchmark 3500kg.

However, with its 6200kg GCM (or how much it can legally carry and tow at the same time) our test vehicle would require a substantial payload reduction of more than half a tonne (525kg) to tow its maximum trailer weight (but it’s not alone there).

And that would leave 470kg of payload capacity, most of which could be used up by the weight of a hefty five-member working crew before you could think about loading any of their tools and other equipment.

Fact is, few (if any) owners would need to tow 3500kg, but it’s important to be aware of these numbers if you do plan to tow that heavy and want to stay on the right side of the law.

The square load tub is 1520mm long and wide and 540mm deep, but with 1146mm between the rear wheel-housings it won’t fit a standard Aussie pallet. However, it will accommodate Euro pallets, if hauling such payloads is important.

The tub’s internal surfaces are protected by a spray-in liner and there are load-anchorage points front and back, with the rears close to floor level (ideal for all loads) and the fronts near the tops of the sidewalls (not ideal for low loads). The tailgate is equipped with hydraulic dampers to assist opening/closing and the handy fold-out step allows easy entry to the load tub.

Cabin storage includes a bottle holder and bin in each front door, a small lower dash compartment on the driver’s right and a slender bin above the glove box on the passenger side.

The centre console has a wireless phone-charging pad, 12V socket and two USB ports up front, plus cup/small-bottle holders and a lidded box at the back with an internal air conditioning cooling vent and sliding upper storage tray.

The rear seat has adequate legroom even for tall people, given I’m 186cm and have about 60mm of knee clearance when seated behind the driver’s seat in my position.

Headroom is adequate though not as generous and the deep contour in the roof lining to allow for the sunroof can make tall rear passengers feel a bit closed-in.

Shoulder room can also be squeezy for three large Aussies, so like all dual cab utes short of a full-size US pick-up it’s okay for short trips but ideal for two on longer drives.

There’s a bin and bottle-holder in each rear door and pockets on both front seat backrests. The 60/40-split seat bases can also fold up and by stored vertically for more internal load space, or to access wheel-changing equipment.

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.

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 $409,744  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...

The Cannon's engine capacity has increased 20 per cent by adopting the Alpha's 2.4-litre four-cylinder turbo-diesel. It produces 135kW of power at 3600rpm and 480Nm of torque between 1500-2500rpm, which represents a 12.5 per cent power increase and 20 per cent more torque.

This is paired with GWM’s new homegrown nine-speed torque converter automatic (previously eight-speed) which has overdrive on the top three ratios and there are steering wheel paddle-shifters for sequential manual-shifting.

The 4x4 system is a ‘torque on demand’ design that transmits power to the rear axle under normal driving conditions to optimise fuel economy, but automatically sends power to the front axle if a loss of rear axle traction is detected.

It also offers a choice of selectable drive modes comprising 'Normal' (default), 'Sport' and 'Eco', plus 4H (4x4 High Range) and 4L (4x4 Low Range). The latter is only for the rough stuff, where the selectable electronic rear diff-lock could also come in handy.

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.

GWM claims official combined consumption of 8.4L/100km and the dash display was showing 9.6 at the completion of our 321km test, which comprised the usual mix of suburban, city and highway driving, of which about one third of that distance was hauling its maximum payload. The engine auto start/stop function was switched off for the duration.

Our own figure of 9.7L/100km, crunched from actual fuel bowser and tripmeter readings, was line-ball with the Cannon’s onboard calculation, which proved its accuracy. It also validated our test vehicle’s real-world sub-10L/100km consumption, which is excellent for a two-tonne-plus ute and gets a big thumbs-up from us.

Therefore, based on our test figure, you could expect a real-world driving range of around 800km from its 78-litre diesel tank.

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.

Even though there’s no adjustment for base-cushion rake or lumber support on the driver’s seat, we didn’t suffer any discomfort during our test. There are also three steering wheel assist modes to choose from comprising 'Light', 'Comfort' (default) and 'Sport'.

The new 2.4-litre engine effectively fills the gap that existed with the previous 2.0-litre, which felt underdone given this vehicle's size and weight. The big 20 per cent increase in torque is a noticeable improvement, as it pulls strongly from low rpm with gearing that keeps it within its peak zone most of the time.

It’s also relatively smooth and quiet and the three drive modes optimise performance in each setting. The Sport mode provides a noticeable increase in response, which in combination with the same setting for the steering is the most engaging drive experience.

The refined nine-speed auto is a sweet-shifting transmission in either auto or manual mode.

We were also pleasantly surprised by a big improvement in ride and handling, as this latest version of the Cannon feels like it finally has the beefier spring rates and damper settings this ute has been crying out for.

It’s also an effortless highway cruiser, with the overdriven top gear ensuring the engine requires less than 1800rpm to maintain 110km/h. However, although wind and engine noise is pleasantly low at these speeds, we did notice tyre noise emanating from the rear tyres into the cabin.

To test its GVM rating, we maxed out the payload to 990kg. This compressed the rear leaf-springs about 60mm, leaving around 40mm of static bump-stop clearance which ensured no bottoming-out on our test route.

It felt stable and sure-footed and the new drivetrain made light work of our 13 per cent gradient, 2.0km-long set climb at 60km/h, displaying ample pulling power in fourth gear to easily haul this load to the summit.

Engine-braking on the way down, in a manually-selected second gear, was arguably the best we’ve experienced in a sub-3.0-litre turbo-diesel with almost a tonne on its back.

Our only gripe is the emergency lane-keeping assist function, which needs more refinement as it creates weird fluctuations in steering weight and aggressively tugs at the wheel when you get anywhere near a white line.

Fortunately, this can be disabled in the vehicle settings menu, but unfortunately must be switched off before each drive.

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.

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.

Like all GWM Cannons, our test vehicle comes with a generous seven-year/unlimited km warranty, which includes five years of roadside assist. Apart from the first service at 12 months or 10,000km, scheduled servicing is every 12 months/15,000km, whichever occurs first.

GWM offers capped-pricing for the first five scheduled services (60 months or 70,000km), which totals $2530, or an average of $506 per service.

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).
