Porsche Cayenne VS Jeep Grand Cherokee
Jeep Grand Cherokee
- Excellent performance from SRT
- Great choice in line-up
- Advanced safety equipment not on all grades
- Cost of servicing is a little high
- Cabin could be more refined
Since the Porsche Cayenne turned the automotive world upside down in the early noughties, it has continued to evolve and has grown to become one of the brand's biggest sellers.
One size up from the mid-size Macan, it's problematic for hardcore Porsche-philes, but there's no doubting this five-seat SUV's success, or the fact that it helps keep the famous German sports car maker well and truly in the black.
And this is the new, third-generation version, with an all-new chassis, fresh engines, and a bunch of dynamic, safety and multimedia tech enhancements.

|Engine Type||4.1L turbo|
Jeep Grand Cherokee
What a time to be alive people. There have never been more SUVs to take your pick from. But while many are excellent, there sure are a lot out there that are a bit... samey, and conservative, a little domesticated.
First it's made in the United States of America, in Detroit, and that's becoming a rarity these days. Next, the line-up is like a kooky gang of super heroes all with different powers.
There's the monster high-performance V8 one which can out accelerate and out handle many sports cars; the tough off-road one that can lift itself higher than its rivals with its air suspension; there's posh one, the popular one nearly everybody buys and the rear wheel drive one hardly anybody does.
|Engine Type||3.0L turbo|
The Cayenne may be the Porsche of SUVs, but you can't have family car size and practicality without a few concessions.
It's fast, beautifully built, and engineered with a special eye for detail, and the well specced Cayenne S is the pick of the bunch for performance and value.
But it's worth remembering the SUV bit. This Porsche is more everyday enjoyment than track day excitement.
Is the Cayenne your kind of premium family truckster? Tell us in the comments below.
Jeep Grand Cherokee7.9/10
Not many SUV brands out there have ranges offering a variety of vehicles as wide as the Grand Cherokee line-up. These are comfortable, good looking, and in nearly all cases, capable off-roaders – particularly the Trailhawk.
The sweet spot of the range is the Limited. It's excellent value, and there's no wonder it's so popular. The SRT is also hard to go past if you're after more of a sledgehammer – at almost $10,000 under 100K it's bang-for-your-buck that can't be beaten.
Is the Jeep Grand Cherokee the best large SUV under $100k? Let us know what you think in the comments below.
The design is new yet familiar. Longer (+63mm), wider (+44mm), lower to the ground, and lower overall (-9mm), yet the wheelbase is unchanged at just under 2.9m.
All models feature LED headlights, and the Cayenne and Cayenne S are identified by their silver grille slats, with the Turbo featuring matt and high-gloss black surfaces plus larger air intakes at the front.
Car-spotters will also notice narrower side windows with a sharper decline at rear (Porsche calls it the Flyline) and the C-pillars tilting forward for a racier look.
A full width horizontal light strip across the tail sits under a clear covering above a three-dimensional version of the Porsche logo.
And wheels now range in size from 19-inch on the Cayenne, 20-inch on the Cayenne S, to 21s on the Turbo, plus optional 22s, presumably for those who drive on billiard table smooth freeways at all times.
And the Cayenne now features staggered or mixed tyres for the first time, that is fatter rubber on the back than the front.
Inside, the biggest change is the adoption of the Panamera's 'Advanced Cockpit', with the central tachometer in the iconic five-gauge instrument cluster flanked by twin 7.0-inch screens to create a blended analogue/digital version of the classic Porsche five dial layout.
Plus, there's the sleek 12.3-inch screen in the centre running everything from nav and vehicle settings to audio control and phone calls, through touch and voice.
Again, it's a direct lift from the Panamera, and the screen layout can be customised to personal preference, with Apple CarPlay standard (but no Android Auto).
Jeep Grand Cherokee8/10
New one look like the old one? Yup, the styling changes are almost unnoticeable, but the trademark seven-slot grille is slimmer, the front bumper has a new design and the fog lights use LEDs.
The Grand Cherokee's look is distinctive with its big toothy grille, high waistline and pumped up guards. It's an American muscle SUV – especially the SRT with its nostrilled bonnet, enormous air intakes, blacked-out face and red Brembo brake calipers.
The new Trailhawk rivals the SRT for attention-seeking-but-still-functional bling with its red tow hooks and badging. Look closely and you'll see small profiles of a WW2 Willys MB Jeep on the wheels, which is a cool touch.
The Grand Cherokee's cabin is comfortable but more functional than stylish, higher grades feel plush with their leather seats and wood trim finishes.
The Grand Cherokee's dimensions reveal all variants apart from the SRT to be 4828mm long and 1943mm wide. The SRT is longer at 4846mm and wider at 1954mm across the hips.
The heights vary depending on the variant with the Laredo and Limited standing 1802mm tall, while the Trailhawk and Overland are 1792mm. The SRT is hunkered down lower at 1749mm.
The Trailhawk and Overland have an approach angle of 36 degrees, a departure angle of 27 degrees and a breakover angle of 22 degrees. Those trump the angles for the Laredo and Limited which are 26 degrees for approach, 24 for departure and 19 for the breakover.
The SRT will still be competent off-road but its approach angle of 18 degrees, a departure angle of 22, and a breakover angle of 18 means it's more suited to less challenging dirt and gravel roads.
Practicality highlights are more storage around the cabin, and a slide and recline adjustable rear seat.
Up front, the glove box is cooled, there are storage compartments under both seats, plus two cupholders, decent bottle holders in the doors, a 12-volt outlet (under the glove box), as well as two USB charge and connectivity ports in a generous console storage box.
Jump in the back and you'll find door bins with space for bottles, map pockets on the front seat backrests, a pair of cupholders in the fold-down centre armrest, plus two USB charge ports and a 12-volt socket in the centre console.
The rear seat's tilt and slide party trick means there's plenty of leg and headroom in the rearmost, fully reclined position. But tweak a lever on the side and a pull handle under the cushion and you can move forward (in stages) to liberate as much as 100 litres of extra cargo space over the outgoing model, while maintaining seating for five (three without legs in the extreme forward position).
Porsche's official description of the rear bench offering “two comfortable seats outside left and right and one centre seat” accurately sums up the relatively squeezy plight of the centre rear passenger.
Cargo capacity is 770 litres with the 40/20/40 rear seat upright, and a handy 1710 with it folded forward. There are four tie-down anchor points, plus a netted storage area on the passenger side, two lights and yet another 12-volt power point.
An auto tailgate is standard on all models, and a 20-inch collapsible spare (with inflator kit) sits under the rear floor.
If towing is your thing the Cayenne's weight ceiling is 3.5-tonne for a braked trailer, and 750kg unbraked. Porsche's 'Trailer Stability Management' system is standard.
Jeep Grand Cherokee8/10
All Grand Cherokees are five seaters. Legroom in the back is just enough… for me. I'm 191cm tall and the only reason I can sit behind my driving position is because of the concave design of the front seatbacks – and that gives me a gap of about 20mm. Headroom is great back there.
Up front there's stacks of head and shoulder room, although the driver's footwell feels a little cramped with the transmission tunnel above the bellhousing seeming to eat into the space.
There's a decent boot with a capacity of 782 litres and under the floor is a full-sized spare with storage space around it - you'll also find a rechargeable torch in the cargo area which 'clicks' into the boot wall.
Storage throughout the rest of the cabin is good with two cupholders in the fold down centre armrest in the back and another two up front. There's a deep centre console bin and bottle holders in all doors.
Price and features
There are three models offered initially, starting with the Cayenne, powered by a 3.0-litre single turbo-petrol V6 for $116,300 before on-road costs. Then the 2.9-litre V6 Cayenne S adds a second turbo and around $40k to the price tag, coming in at $155,100.
The powerhouse Turbo tops the line-up with a 4.0-litre twin-turbo petrol V8 under the bonnet, and cost of entry sitting at $239,400.
Not a diesel in sight (for Australia) for the time being, with an E-Hybrid variant due here closer to the end of this year.
As you'd expect in this part of the market the standard equipment list is solid, with the Cayenne featuring partial leather trim, cruise control, LED headlights, daytime running lights and tail-lights, rain-sensing wipers, dual-zone climate control, privacy glass, front seats with 14-way electric adjustment and memory settings, remote central locking with 'Keyless Go', the twin digital instrument displays, multi-function sports steering wheel (with gearshift paddles), auto tailgate, 'Porsche Active Suspension Management (PASM - with adaptive dampers), 19-inch alloy wheels, and 'Porsche Communication Management' (PCM) with the 12.3-inch screen controlling nav, phone and audio (10-speaker, 150 watt and digital radio).
As well as it's more powerful twin-turbo V6 engine, the Cayenne S adds 'Adaptive PASM' (with air suspension), 20-inch alloy rims, twin dual-tube tailpipes, dynamic (directional) LED headlights, a dual-pane panoramic sunroof, heated front seats, pedal faces in stainless steel, a 710-watt Bose 'Surround Sound System' with 14 speakers (including subwoofer), and metallic paint in any one of seven colours.
Then the Cayenne Turbo piles on the power and luxury with the twin-turbo V8 joined by 21-inch alloys (in dark titanium with highly polished surfaces) including wheel arch extensions in the exterior colour, 'Porsche Active Aero' (with adaptive roof spoiler), scrolling LED indicators, 'LED Matrix' headlights, 'smooth finish' leather upholstery, 18-way electronically-adjustable 'Adaptive Sports' front seats with unique trim and fatter side bolsters, front and rear seat heating (and ventilated/cooled front seats), exterior mirrors with kerb-view parking aid, a heated steering wheel, 'cross-brushed' aluminium interior highlights, and Alcantara roof lining (cloth on base and S).
If you're ready to stump up the big bucks, that's a heap of fruit to go with this car's comfort and performance potential.
Jeep Grand Cherokee8/10
There's the $52,500 petrol Laredo 4x4 (the diesel version is $5500 more); then the popular Limited which lists at $62,500 ($5500 more for the diesel); the diesel-only Trailhawk at $74,000 is a new off-road hero variant; then there's the plusher $80,000 Overland with the same engine, and finally the high performance, petrol-only SRT for $91,000.
All V6 petrol engine variants have increased by $500 over the outgoing model, while the diesels stay the same – apart from the Overland which has risen by $1000. The SRT has also gone up by $1000.
At the most affordable end of the range the Laredo grade comes standard with 18-inch alloy wheels, an 8.4-inch touchscreen (5.0-inch in the 4x2), 7.0-inch instrument cluster display, reversing camera, front and rear parking sensors, power adjustable and heated front seats, proximity unlocking and start button, auto headlights and wipers, and dual-zone climate control.
The Limited grade picks up the Laredo's features and adds 20-inch alloy wheels, a power tailgate, leather seats, a nine-speaker Alpine stereo, sat nav, dark-tinted rear glass, heated steering wheel and dual exhaust.
The Overland gets the Limited's features and adds a panoramic sunroof, adaptive cruise control, auto parking, ventilated front seats, plus a wood and leather steering wheel.
The SRT gains the Overland's features and adds a flat-bottomed steering wheel, leather and suede seats, launch control, active noise cancellation and adaptive damping.
Engine & trans
The new car's engines are lifted from the Panamera, and not only feature more power than the outgoing Cayenne, but Porsche claims improved fuel economy and lower emissions.
All feature an alloy block and heads, the Cayenne's 3.0-litre, single turbo V6 delivering 250kW from 5300-6400rpm, and 450Nm from just 1340rpm all the way to 5300rpm.
This 'base' engine features direct fuel-injection, 'VarioCam Plus' (variable cam control on the inlet and outlet side, and valve-lift adjustment on the inlet side), as well as the turbo located in the engine's vee to help minimise lag.
The Cayenne S's 2.9-litre V6 adds a second turbo to deliver 324kW from 5700-6600rpm, and 550Nm between 1800rpm and 5500rpm. It's shorter stroke design helps lift the rev ceiling by 300rpm (to 6800rpm).
Then the Cayenne Turbo adds two more cylinders to pump out no less than 404kW (542hp) across a narrow plateau from 5750-6000rpm, and 770Nm between 1960rpm and 4500rpm. The V8 also locates the turbos in the 'hot vee', but drops back to 'VarioCam' (variable cam control on the inlet and outlet side) without valve-lift adjustment on the inlet side.
All models now feature an eight-speed 'shift-by-wire' 'Tiptronic S' auto transmission, with drive going to all four wheels courtesy of Porsche's Active Traction Management system. The gear set in the Turbo (including the final drive) is slightly taller, although the seventh and eighth ratios are overdriven on all models to maximise fuel economy.
Claimed 0-100km/h times (with optional Sport Chrono package numbers in brackets) are: Cayenne – 6.2sec (5.9s), Cayenne S – 5.2sec (4.9s), Cayenne Turbo - 4.1sec (3.9s).
And if you have a very long driveway, leading up to your (presumably) very large house, you'll be pleased to know maximum velocity for the Cayenne is 245km/h, rising to 265km/h for the S, and a stonking 286km/h for the Turbo.
Jeep Grand Cherokee9/10
The engine line-up for the Grand Cherokee is straightforward. The petrol engines for all but the SRT are an upgraded version of the previous model's 3.6-litre V6 with 3kW more power for a total of 213kW. Torque stays put at 347Nm.
The SRT is special – under that nostrilled bonnet there's 6.4 glorious litres of naturally aspirated V8 Hemi making 344kW/624Nm. Jeep has left this one untouched from the previous model, too.
The Trailhawk and Overland have Jeep's 'Quadra-Drive II' 4WD system which makes them more capable off-road then the Laredo and Limited with their 'Quadra-Trac II' permanent 4WD.
The major difference between the 4WD systems being that Quadra-Drive II has an electronic slip differential while the other uses traction control and braking to counter slippage. The SRT has the 'Quadra-Trac Active On-Demand' 4WD system.
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle ranges from 9.2L/100 km for the Cayenne (emitting 209g/km of C02 in the process), to 9.4L/100 km for the Cayenne S (213g/km), and 11.9L/100 km for the Cayenne Turbo (272g/km).
All models feature auto start-stop (with coasting), your only fuel option is 98 RON premium unleaded, and you'll need 90 litres of it to fill the tank.
Jeep Grand Cherokee7/10
The diesel Laredo, which is 4WD, has a claimed combined fuel consumption number of 7.5L/100km. Ditto for the diesel Limited, Trailhawk and Overland.
After an hour of driving in the Trailhawk on highways and country roads our trip computer was reporting 11.7L/100km.
The SRT likes a drink. The V8 petrol engine has a claimed combined figure of 14.0L/100km and that's why the SRT didn't make it into the top five most fuel efficient SUVs list.
The new Cayenne sits on the VW Group MLB Evo platform, which also underpins the Audi Q7, Bentley Bentayga, Lamborghini Urus, and the soon-to-arrive new generation VW Touareg.
It uses a lot of aluminium and lightweight high-strength steel which, in concert with the alloy body panels, makes the car not only stiffer, but lighter by up to 65kg.
We've driven each model over a two-day launch program in The Barossa Valley in South Australia, and can confirm the base Cayenne is quick, the S is properly fast, and the Turbo is ballistic.
The transmission is a conventional eight-speed auto, rather than Porsche's PDK dual-clutch, and shifts are quick but smooth in normal mode, transitioning to a sharper, even more precise response in Sport or Sport Plus.
Porsche stands proudly on its reputation as a great sports car maker and says the Cayenne fits easily into that context. But let's face it, this is a two tonne SUV, and while it's dynamically outstanding, it's no 911.
All models feature multi-link suspension front and rear including active dampers, with varying levels of suspension sophistication as you walk up the range, to three chamber air suspension on the Turbo.
On quick twisting B-roads it's fast, in the case of the Turbo, bloody fast. It grips hard thanks to fat Z-rated rubber and active drive distribution makes sure it puts its power down perfectly. But no matter how sophisticated the suspension tech, it still feels large and relatively top heavy.
The electromechanical steering is light, and while it's accurate, no matter which mode you're in road feel is modest.
Not surprisingly, the ride firms up in tune with sportier drive modes, but in Comfort, even the Turbo on 21-inch rims, soaked up the irregularities of at times choppy rural roads with surprising ease.
Given the car's mass and performance potential braking is an understandable priority, with even the base model featuring big ventilated rotors all around with four piston calipers at the front and two at the back.
The S ups that to six piston front and four at the rear, while the Turbo debuts Porsche's 'Surface Coated Brake' a Tungsten-Carbide coating on the discs and special pads for longer life and less dust. Of course, the front calipers are 10-piston with four at the rear (and they're white just to prove brake dust isn't a problem).
In typical Aussie conditions these monster brakes are like cracking a walnut with a sledgehammer. Stopping power (on all models) is immense, and pedal feel is agreeably progressive.
We also headed off-road through rutted dirt and rocky climbs, and with five drive and chassis modes at its disposal the Cayenne ate it up.
The different off-highway modes ('Gravel', 'Mud' and 'Rock') will lock and unlock the centre and rear diff as required and the adjustable hill descent control made crawling down steep slopes a breeze. You can even option up an 'Offroad Package' bringing extra protection for vital components, as well as off-road specific info in the PCM and a compass display on the dash.
If you need to think about the dips and climbs on your country retreat, or maybe just the pitch of your driveway, the Cayenne and Cayenne S's approach and (with the Turbo in brackets) is 25.2degrees (23.3), ramp over is 18.7degrees (16.7), departure is 22.1degrees (20.4), ground clearance measures 210mm (190mm), and fording depth is 500mm (475mm).
Jeep Grand Cherokee8/10
The Trailhawk and the SRT were the only variants available to test drive at the launch of the updated model.
The program was pretty intensive with an off-road leg, a stint at a racetrack and plenty of road driving in between.
The hilly off-road course we took the Trailhawks through wasn't the most challenging, but the rain changed that a bit making the grassy slopes and clay ruts as slippery as ice.
With the Trailhawk in low range and on its highest air suspension setting giving us 260mm of ground clearance we wriggled our way through the off-road course fairly easily. There were some steeper sections which required a bit of brute force and momentum to combat slippery clay and gravity but the Jeeps soldiered through without any dramas, and plenty of hilarious fun.
The Trailhawk's Kevlar-reinforced tyres weren't needed on this soft stuff, but there are thousands of kays of tyre-killing tracks with rocks like spear heads lying in wait all over Australia where they'd be handy.
Grand Cherokees all have a unibody construction, so if you're looking for more of a hardcore off roader in the Jeep range then the body-on-frame Wrangler may be a better bet.
The unibody construction gives the Grand Cherokee a more car-like ride and on the road the Trailhawk was comfortable and composed, although that air suspension is a little floaty.
At 100km/h the Trailhawk lowers itself for better aerodynamics, but there was a decent amount of body roll when pushing hard through corners… unlike the SRT.
The SRT's suspension is set up for higher performance with Bilstein adaptive dampers and hollow stabiliser bars front and rear. Sport and Track modes firm the suspension for better handling along with making the throttle more responsive.
I've driven the SRT on racetracks and the road before, but some quick laps around New Zealand's Pukekohe Park circuit brought back the grin that only 2.4 tonnes of metal seeming to defy all the laws of physics can induce.
That naturally aspirated V8 Hemi is a lazy beast that seems to take it's time to wind up rather than deliver the same brutal kick of the twin-turbo V8 in a Mercedes-AMG GLE63, still 0-100km/h in a claimed 4.9sec is quick. What it lacks in spontaneity it makes up for in theatrics – the gurgle at idle is delicious and it gets angrier the more you kick it in the guts.
The launch control function in the SRT is foolproof, too. Just press the button which looks like a dragstrip 'Christmas tree' on the centre console, place your left foot on the brake and plant your right foot on accelerator – release the brake and enjoy the jump to hyperspace… well, almost.
Active safety systems include the usual suspects like ABS, ESC, and traction control (ASR), with the addition of other features under the 'Porsche Stability Management' umbrella, including ABD (torque vectoring by braking), and MSR (prevents slip on the drive wheels produced under engine braking)
There's also AEB (although the Porsche system doesn't bring the car to a complete stop), 'Park Assist' (front and rear) including 'Surround View', 'Lane Keeping Assist', 'Lane Change Assist', and tyre pressure monitoring.
But if all else fails passive features include an active bonnet (activated by pedestrians, cyclists, etc detected by the front camera), driver and front passenger airbag, knee airbags for the driver and front passenger, front side airbags, rear side airbags and full-length curtain bags.
There are three top tether points across the back seat with ISOFIX anchors on the two outer positions. ANCAP hasn't assessed the third generation Cayenne so far, but its Euro NCAP affiliate awarded a left-hand drive, 3.0-litre diesel model a maximum five stars in 2017.
Jeep Grand Cherokee7/10
The Jeep Grand Cherokee has been awarded the maximum five-star ANCAP rating. All Grand Cherokees have seven airbags, a reversing camera, trailer sway control, but only the Overland and SRT grades come standard with advanced safety equipment such as AEB and lane departure warning. The equipment can be optioned on all grades from the Limited up.
You'll find three top tether points and two ISOFIX points in the second row.
There's also a full-sized spare wheel under the boot floor.
The update has brought two more advanced safety items – blind spot monitoring and rear cross traffic alert but these are only standard on the Overland.
The Cayenne is covered by Porsche's three year/unlimited km warranty, with paint covered for the same period, and a 12-year (unlimited km) anti-corrosion warranty also included.
Porsche Roadside Assist provides 24/7/365 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer, and the main service interval is 12 months/15,000km.
No capped price servicing is available, with final costs determined at the dealer level (in line with variable labour costs by state/territory). Indicative scheduled costs for the first four years/60,000km line up as: 12 months/15,000km (annual) - $695, 24 months/30,000km (intermediate) - $695, 36 months/45,000km (annual) - $695, and 48 months/60,000km (major) - $1300, for a total of $3385.
Jeep Grand Cherokee8/10
There's also life-time roadside assistance if the vehicle's serviced at a Jeep service centre.
For the 3.0-litre diesel servicing is recommended annually or every 20,000km and capped at $665 for the first, $1095 for the second, then $665, then $1195 and at five years it'll be $665.
