Jeep Renegade vs Porsche Cayenne

What's the difference?

Rugged, dependable and good off-road are the most obvious qualities of the Trailhawk. It stands out from the rest of the mini-SUVs by being able to do the S and the U with plenty of vigour.

It's just a shame that its on-road manners can't match that of its big brother, the Cherokee. Unless you're planning on proper off-roading, the Trailhawk might not be quite what you're looking for.

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.

In what is absolutely not a coincidence, the Renegade immediately conjures up the Wrangler. Upright grille from the Willys Jeep (references abound here), round headlights, squared off wheel arches to mimic the Wrangler's guards, short overhangs and big rear view mirrors.

The 17-inch wheels look completely lost in the wheelarches which are even more cavernous owing to the Trailhawk's 50mm of extra ride height. The wheels are also a bit cheap looking but will probably survive the belting the car is intended to take.

Less rugged is the interior, despite a fairly self-conscious effort to make it look and feel chunky. The front seats are flat and unsupportive with the rears just as lacklustre making sure everyone is sliding around together. Luckily, front passengers get a dash-mounted grab handle.

It seems quite well put together, however, but with carpets and easily-marked plastics, you'll hope your passengers don't bring the mud in with them too often. And the "Since 1941" stamped into the steering wheel can go.

The dashboard is reasonably clear and has plenty of information to share via the screen between the dials but whoever thought marking the redline with a water splash graphic in bright orange should probably rethink their design decisions.

Storage is limited to two cupholders up front, door pockets in each door and nets on the front seat backs.

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.

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 Trailhawk is powered by Fiat's 2.4-litre four naturally-aspirated four-cylinder producing 129 kW and 230 Nm. Jeep reckons you'll get 7.5L/100km on the combined cycle. Our mostly city driving with a longish motorway run produced an 11.0L/100km average over a week.

The transmission is a nine-speed ZF automatic driving all four wheels.

The Trailhawk also has Jeep's five mode Selec-Terrain system which should cover pretty much every eventuality – Auto, Sport, Mud, Sand and, just for the Trailhawk, Rock. The Trailhawk is rated to tow 400kg unbraked and 907kg braked.

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.

The Trailhawk name suggest that things are going to get muddy – compared to the rest of the range, the range-topper rides 50mm higher and has exposed, easy-to-reach tow hooks in the fairly unlikely event you get stuck. It also has a 20:1 low-range crawl ratio and Active Drive 4x4 which means it can switch between front and all-wheel drive. It'll also wade through almost half a metre of water. It's a genuine mud-plugging proposition and will take on some much bigger machinery out in the bush.

On the road, where we spent all our time in the Renegade, it's not what you'd call particularly inspiring. There's a number of sources of noise that contribute to a less than quiet cabin and having to constantly correct your course at freeway speeds adds to the tiring nature of the Renegade.

It's much better at lower speeds, pottering around but then again, its nine-speed transmission needs a lot more work on the shift mapping because it seems to forget which gear it needs to be in when you sink the right foot. If you don't need the Trailhawk's extra off-road goodies, consider the 1.4 litre Limited or Longitude.

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.
