Isuzu MU-X vs Porsche Cayenne

What's the difference?

The MU-X has plenty of appeal as a daily driver – dependable and it’s a proven 4WD wagon.

Does the 2.2-litre engine add anything substantial to the mix?

Well, it's better than the 1.9-litre, that's for sure, and there's a lot to like about this MU-X in terms of its off-road capability, driver-assist tech, standard features and all-round driveability. And, while the LS-T lacks the top-shelf polish of the X-Terrain, it’s still an appealing potential purchase.

But the 3.0-litre option is better because while the 2.2L is very effective off-road and general day-to-day driving, it lacks grunt and has to work that much harder and is that much noisier under load than the 3.0-litre in most driving scenarios, including 4WDing.

There is a lot riding on this new Cayenne Electric, it is the sales leader for the German brand and if it suffers the same sales decline as the Macan, that will be a big concern for Porsche.

The good news is it’s an impressive all-rounder, with an incredible breadth of capability. But so is the electric Macan.

Going electric hasn’t diminished its trademark Porsche elements, and instead has amplified them in many respects. The speed is nothing short of staggering in the Turbo, but across the range the on and off-road driving ability is impressive. 

Plus it has the kind of spacious, well-considered and premium appointed cabin you should expect for a luxury SUV.

There are two key differences that could see it succeed where the Macan has faltered. Unlike the Macan, Porsche’s decision to give Cayenne buyers the option to stick with internal combustion if they prefer, is likely to ensure it remains a popular member of its line-up for years to come.

And while the Macan was perhaps too much, too soon, the Cayenne arrives at a time when Australians are embracing electric cars more than ever before. Although the luxury and performance end of the EV market is growing more slowly than the mainstream.

As for the pick of the range, as mind-blowing as the Turbo is, the truth is (like pretty much every Porsche model) the entry-level Cayenne is arguably the pick of the bunch. It has all the performance you’ll reasonably need and offers a good blend of capability and luxury for the lowest price.

Note: CarsGuide attended this event as a guest of the manufacturer with travel, accommodation and meals provided.

In terms of appearance, the MU-X remains largely unchanged from the most recent iteration. And that’s a good thing. It’s blocky enough to be recognisable but sleek enough to remain inoffensive. Worth noting the door handles, window trims, front fender accents, roof rails, and side steps on the LS-T are gloss black.

Inside, nothing much has changed (other than a newly-introduced idle start/stop button) and, as such, the MU-X retains a low-key familiarity that makes it a comfortable space. Generally, design-wise, the MU-X more than holds its own against the likes of the Toyota LandCruiser Prado and Ford Everest.

For all the positives of continuing to offer the previous generation Cayenne alongside the new one, it does come with some downsides too. The most obvious is unmissable design differences between the older generation and this newer one.

This new electric version has the same basic silhouette of the previous Cayenne, but the details give it a distinctive look. Being electric it needs to cut through the air as efficiently as possible, so this new model is longer and lower than the internal combustion versions.

The details of the design also give it a sharper, more modern look too. Not that the previous Cayenne suddenly looks old and outdated, but if you stick with petrol power you will be sacrificing the latest styling.

Another surprising design element with this new model is an optional off-road package, which includes a unique front bumper for greater off-road clearance and approach angle. It’s unlikely that too many Cayenne Electric owners will head deep into the bush, but for those who want to, the unique bumper will help them go further. 

However, it does create a rather unusual look, as it has quite a pronounced undercut, or what I referred to as an ‘overbite’ that definitely doesn’t look as well-proportioned as the standard bodykit.

Inside, for all the hype around Porsche performance, one of the brand’s standout features has always been interior design. 

This new Cayenne looks really interesting inside, with curved screens for the digital instrument display and the multimedia system, as well as the option to add a third screen in-front of the passenger. 

The overall level of fit and finish, the detail and quality of the materials is exactly what you’d expect from a premium brand and an SUV at this price point.

The interior has a familiar and practical feel about it and the cabin is an easy space in which to become comfortable. Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C (front and second row) and 12V.

Storage places include recesses for the bits and pieces from your pockets, a deep-ish centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors. There are also cupholders either side of the third row.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume and access sat nav).

Seats are comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is back there.

My camera guru/photographer/sergeant-at-arms, Glen Sullivan, reminded me that the third-row seats don’t have ISOFIX or top-tether points for child seats. Thanks, mate.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows stowed away.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall. The MU-X’s full-size spare (bravo!) is attached to its undercarriage.

As for the space and practicality, once again Porsche showcases that it’s not a one-trick pony brand. As fast as the Cayenne Electric is - and is very fast - the designers have also ensured it is a genuinely spacious vehicle for a family.

The second row space is good, enough to take two adults in comfort and easily accommodate three kids.

The SUV is obviously the more practical of the pair, with the Coupe losing some rear headroom.

As for the boot, space varies between 781L for the Cayenne SUV and 747L for the S and Turbo SUVs, while the Coupe looks sleeker but comes at the expense of cargo capacity, dropping to 534L for the Coupe and Coupe S and just 500L for the Coupe Turbo. 

The technology integration is well-considered too. One highlight is the new curved central multimedia screen, which has a palm rest that extends out from the centre fascia to make it more ergonomic to use the screen. 

The intuitive menu, as well as the physical controls for the volume and climate control, plus the ability to integrate the smartphone apps, means the key non-driving functions are incredibly easy-to-use, even on the move. 

Integrated into that palm rest is a large centre console space between the front seats, which has both wireless smartphone charging as well as four USB-C ports and two cupholders. It means there is plenty of small item storage space to go with all the room for people.

Starting with the basics, there are two different variants of the new Cayenne - the SUV and Coupe - and three trim grades to choose from - the entry-level model (known only as ‘Cayenne’), the sportier S and the flagship Turbo.

A major factor in the sales decline of the Macan is undoubtedly the rising cost of the car, which leapt up as much as $30,000 on some variants. So Porsche has been more careful with how it has positioned the Cayenne.

The new electric Cayenne is still a more expensive proposition, with the standard Cayenne SUV starting at $167,700 ($173,500 for the Coupe), which is over $20,000 more expensive than the equivalent petrol-powered model. It should be noted that that doesn’t factor in the increased performance and level of standard equipment, which includes air-suspension across the entire electric range.

Moving up the range, at $193,000 (Coupe - $194,500) the Cayenne S Electric is only just over $8000 more than its petrol alternative but the $259,800 (Coupe - $272,000) Turbo is actually more than $40,000 cheaper than the Turbo E-Hybrid. So it is not as simple as saying the electric Cayenne costs more across the board.

However, this isn’t the only one of the key differences between Porsche’s Macan and Cayenne strategy. The Cayenne petrol and hybrid models are here to stay for the foreseeable future. Rather than being completely replaced by the electric version, Porsche has learned its lesson and is giving customers more choice. 

Officially Porsche hasn’t confirmed a new-generation of Cayenne petrol/hybrids, but all signs point to a new version coming in the next few years to carry on internal combustion power deep into the 2030s.

Porsche Australia also knows that the competitiveness of our very crowded market means extra equipment is a good idea. So all Australia-bound Cayenne Electrics come relatively well equipped, and more so than most overseas markets. For example, all local examples are fitted with air suspension as standard.

For the Cayenne, standard equipment includes:

• 20-inch alloy wheels
• Matrix LED headlights
• Illuminated ‘Porsche’ lettering on the bootlid
• Panoramic glass roof
• Dual-zone climate control
• Eight-way adjustable sports seat
• 10-speaker sound system
• Wireless Apple CarPlay and Android Auto 

For the extra money - aside from extra performance we’ll detail later - the Cayenne S adds: 

• 21-inch alloys,
• Four-zone climate control
• Bose surround sound audio system with 14 speakers

The Cayenne Turbo adds even more performance as well as:

• 22-inch alloys
• Unique lower front bumper
• Porsche Active Aero Dynamics with active Aeroblades
• HD-Matrick LED headlights
• Variable light control for the panoramic roof

Adaptive sports seats with 18-way adjustment

This MU-X has a 2.2-litre, four-cylinder, turbo-diesel engine, producing 120kW at 3600rpm and 400Nm between 1600-2400rpm and it’s matched to an eight-speed automatic transmission.

Worth noting the 3.0L MU-X has a six-speed auto and produces 140kW (at 3600rpm) and 450Nm (1600-2600rpm) while the outgoing 1.9L MU-X has a six-speed auto and produces 110kW (3600rpm) and 350Nm (1800-2600rpm).

While the 3.0-litre has always been unstressed in most driving scenarios – even low-range 4WDing – the 2.2-litre feels underpowered. More about that in the ‘Driving’ section below.

The MU-X has a part-time 4WD system which includes a dual-range transfer case (with high- and low-range 4WD) and a rear diff-lock. The driver is able to shift from 2H (two-wheel drive, high-range) to 4H (4WD high-range) while on the move up to speeds of 100km/h. The diff-lock may only be engaged when the vehicle is in 4L (4WD low-range).

The MU-X also has a switchable terrain mode system which tweaks the engine, transmission and traction control to suit the driving conditions. 'Rough Terrain' mode, like a steroids-enhanced off-road traction control, is king of these modes when you’re off the bitumin.

As mentioned earlier, there are three initial Cayenne Electric variants and each offer a different powertrain option. All are dual-motor, all-wheel drive but the power levels vary greatly depending on what you spend.

The standard Cayenne Electric comes with 300kW (325kW on Overboost), which is enough for this five-seat, family friendly SUV to launch 0-100km/h in just 4.8 seconds, which is genuinely impressive.

However, stepping up to the Cayenne S raises the power level to 400kW (490kW on Overboost) and drops the 0-100km/h time to 3.8 seconds.

Finally there’s the Cayenne Turbo, with up to 850kW of power and a claimed 0-100km/h capability of just 2.5 seconds. Which is borderline crazy for such a big SUV. 

It is worth explaining that the 850kW claim for the Cayenne Turbo is only available for short bursts of performance when you activate Overboost, and the ‘standard’ output for the two electric motors is 630kW, which may sound like a lot less but is actually more than enough to make the Cayenne Turbo feel fast anytime you need more performance.

Official combined cycle (urban/extra-urban) fuel consumption for this MU-X is 6.7L/100km. The 1.9L MU-X offers 7.4L/100km while the 3.0L offers 7.6L/100km.

Actual fuel consumption on this test was 8.7L/100km.

The MU-X has an 80-litre fuel tank, so, going by that on-test fuel consumption figure, you should be able to get a driving range of about 920km. But remember, your fuel consumption may be completely different to mine because chances are you'll have friends, family pets, sporting equipment, camping gear, the whole kit and caboodle on board. I've only been carrying vehicle recovery gear, MaxTrax, and a first-aid kit, so I haven't had a huge amount of weight on board.

The Cayenne is Porsche’s third electric model, after the Taycan and Macan, and it shows. The brand has taken battery production in-house for the Cayenne, producing the 106kWh unit at its own factory in Eastern Europe.

Range is rated at 542km for the Cayenne, 571km for the Cayenne S and 537km for the Cayenne Turbo.

Thermal efficiency is the key selling point for Porsche, as it unlocks not only the peak performance but also the repeatability that allows the Cayenne to launch so quickly over and over again. It’s notable, that unlike most other EVs that get slower the more time you extract peak performance out of them, Porsche was happy for us to undertake multiple acceleration runs in the same vehicle.

But that’s not the only trick Porsche has up its sleeve. It will be introducing inductive charging with the Cayenne. This means you’ll be able to buy a charging pad you can place on the floor in your garage, and simply drive it, park on top of it and the Cayenne will charge wirelessly.

This has the potential to be a game-changer for EV buyers as it removes the need to plug in to replenish the batteries, making life even easier for owners. It’s not available in Australia at the time of publication, but the company says it will be available from the fourth quarter and all Australian-delivered models, even those sold now, will be able to be retrofitted to take advantage of the technology.

Before we launch into the off-roading section of this test, it’s worth noting the MU-X has always been decent on-road; composed, reasonably refined (for a 4WD wagon, anyway) and comfortable. And thankfully, with the 2.2-litre engine, not all of those characteristics have been thrown out the window.

It is quite noisy, especially under pressure when you have to do some heavy acceleration or when you have a bit of gear on board. When it has to work that bit harder than it usually does, it can become quite noisy. Admittedly, the 3.0-litre MU-X is also quite gruff, but there's an edge to the roughness in the 2.2-litre that is very noticeable on road.

This MU-X is quite sluggish off the mark, exhibiting a disconcerting lag under heavy throttle from a standing-start. And it’s far from the most dynamic vehicle to drive. But it has a tractability about it that manages to mostly negate these flaws.

Otherwise, the new eight-speed auto deserves credit as it’s slick and smooth in application and feels right at home in this wagon.

Now to off-roading. The MU-X is still very capable. In fact, even with the 2.2-litre engine, it remains one of the better-performing 4WD wagons straight out of the dealership, in terms of pure off-road capability.

The 3.0-litre MU-X is not the torquiest in this segment, but it offers ample pulling power available across a wide rev range – count on peak torque between 1600rpm and 2400rpm – and it delivers that pulling power in an even-handed fashion. The 2.2-litre MU-X has to work harder than its stablemate, and it’s noisier and harsher.

However, those characteristics don’t take away from how effective this MU-X is because it offers impressive off-road performance. It still has a decent amount of low- and mid-range torque, which makes dirt-road cruising and low-speed 4WDing easy.

The MU-X has part-time 4WD with high- and low-range 4WD gearing, a rear diff lock and overall it retains all of that off-road capability the 3.0-litre MU-X has been renowned for – so you don't lose any efficacy there.

The line-up’s off-road traction control system, which once was a bit patchy in its effectiveness, has gone through a couple of phases and it’s been recalibrated/tweaked over the years and it is much better now.

Of course, the MU-X also has Isuzu’s much-vaunted Rough Terrain mode (a form of early-acting off-road traction control which converts lost grip into torque for the wheels with grip), and it is smooth and effective, giving the driver better overall control in challenging terrain.

Some of this MU-X’s listed off-road angles appear shallower than the 3.0-litre MU-X’s – approach: 23.9 (3.0L = 29.2), departure: 26.4 (3.0L = 26.4) and ramp-over: 19.6 (3.0L = 23.1) – but, even if that is the case, it has very similar driving characteristics in low-speed, low-range four-wheel driving to its 3.0-litre stablemate.

If you drive with control and consideration, you shouldn't have any trouble tackling light to moderate 4WDing in this MU-X. It could even, if push comes to shove, handle challenges that may be considered by some to be on the edge of hard-core 4WDing – for a showroom-standard 4WD wagon anyway.

Ground clearance is 235mm and wading depth is 800mm, so there’s an adequate amount of clearance to work.

The MU-X – with a turning circle of 11.6m and a kerb weight of 2130kg (3.0L = 2185kg) – feels quite nimble on bush tracks.

This wagon’s wheel travel – how far the axle can move up and down relative to the chassis – has more than an adequate amount of flex, stretching its tyres close, if not all the way, to the dirt.

A noticeable trade-off is its 20-inch wheel-and-tyre combination, which is best suited to sealed surfaces and so are far from ideal for dirt-track touring. There’s an easy remedy, though. Buy a set of decent all-terrain tyres on 17- or 18-inch rims to replace the showroom-standard 265/50R20 Highway-Terrain tyres. If you are using your MU-X, avoid dropping pressures too much because you’ll risk sidewall pinches and punctures on these low-profile road tyres.

In terms of packability: the 2.2L MU-X has a listed payload of 670kg, whereas the 3.0L version offers 615kg.

The 2.2L MU-X can legally tow 750kg (unbraked trailer) and 3500kg (braked), so theoretically you can tow the same load as a 3.0-litre MU-X. But, as mentioned, the 2.2-litre engine feels underpowered, even in general day-to-day driving, so with a load and/or towing that’s an added burden.

For reference, the 2.2L MU-X has a listed gross vehicle mass of 2800kg and gross combined mass of 5900kg.

Porsche Australia invited us to drive the new Cayenne Electric in Port Lincoln, South Australia. While a picturesque part of the country, it seemed like an unlikely venue to test drive a new Porsche, as it’s typically Ford Ranger/Toyota HiLux country.

But one of the reasons Porsche launched the Cayenne Electric in regional South Australia was because they had managed to find a small airstrip we could use to fully explore the acceleration potential. 

Even some operator error, which meant my launch was using ‘just’ the 630kW, the acceleration was sickeningly fast and had me hitting more than 170km/h in just 200m. With the full 850kW unleashed the Cayenne is actually faster 0-100km/h than Porsche’s hero sports car, the iconic 911 Turbo S. 

That alone is a remarkable achievement, but Porsche had a few more reasons for taking us to Port Lincoln. After a drive on some sealed roads, which demonstrated the SUV's on-road composure, we found ourselves heading off-road… more off-road than I thought possible (or at least sensible) in a Porsche.

After surviving some of the gnarliest rocky roads, we found ourselves in some stunning sand dunes. We were driving the Cayenne S with the optional off-road package but the only other modification was to let down the tyres.

Carving through sand dunes like you’re in the Dakar Rally is likely to be a rare job for the Cayenne Electric, but the fact it is capable is immensely impressive and helps to demonstrate the breadth of capability that this electric SUV has.

But Porsche wasn’t finished showing off just how multi-talented the Cayenne is. 

They had a Cayenne Turbo attached to a trailer, carrying the previously beaten 911 Turbo S, to prove that it can live up to its claimed 3500kg towing capacity.

Towing a nearly $600k sports car with a $260k SUV is an expensive way to demonstrate the point, but the Cayenne didn’t miss a beat. Certainly the battery was dropping more rapidly than it was unladen, but the electric Cayenne underlined that it can do everything the petrol versions can manage (at least over a short distance).

As for safety, the Cayenne Electric is as well equipped as you should expect a car at this price to be. There are all the features that have become the norm, including speed limit warning, autonomous emergency braking, lane keeping assist, etc.

But it’s not the fact that it has all the safety features that’s impressive, it’s the level of calibration. Yes, the speed limit warning will go off if you speed, but generally the other safety systems were very well-behaved and understated during our drive.

However, the only caveat with that is our drive was almost entirely in regional areas, so we should reserve final and definitive judgement until we get it into the urban environment. 

As for its safety rating, the Cayenne was crash tested by Euro NCAP in December 2025 and awarded a maximum five-star score. It is unlikely ANCAP will crash test such an expensive model here, so expect the same rating to carry over barring something unusual.

The MU-X has a six-year/150,000km warranty and seven years of roadside assistance. Unlimited km in the warranty would be welcome.

Service intervals are scheduled for every 12 months or 15,000km, whichever occurs soonest.

Capped price servicing covers the first five scheduled services for MY24 and later vehicle models (up to 5 years/75,000km – whichever occurs first) – at a flat price of $469 for each service.

Isuzu Ute Australia has a nationwide network of more than 160 dealer sites.

The Cayenne Electric is covered by Porsche’s usual three-year/unlimited kilometre warranty, and the battery gets eight years of coverage.

Both of these are fairly standard by historical terms, but with so many luxury brands - including Audi, BMW, Lexus and Mercedes-Benz - all now offering five years of coverage, it does leave Porsche lagging behind.

Servicing intervals are every 12 months or 15,000km, whichever comes first, which is standard for an internal combustion engine vehicle.

Porsche doesn’t offer capped-price servicing, so prices may vary from dealer to dealer. However, the brand does sell a special EV-focused ‘Porsche Scheduled Maintenance Plan’ that costs $1995 for three years, $3695 for four years and $3995 for five years of servicing.
