Porsche Cayenne VS Mercedes-Benz GLE-Class
- In-line six engine
- Grand interior
- High-tech features
- Three-year warranty
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.

Not so long ago, even the idea of 'coupe SUV' would have been considered just a little bit silly.
But not anymore. This almost contradictory bodystyle is well and truly here to stay, as evidenced by the expanding catalog of available models pouring out of premium automakers.
Benz tells us, for example, that coupe versions make up some 25 per cent of its GLE sales in Australia.
Which brings us to this car – the second-generation GLE coupe. We were sent to its international launch to find out what’s new, what’s changed, and what Benz has in store for the Australian market, come its arrival in Q3 of 2020. Read on to find out what we discovered.
|Engine Type||2.0L 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.
Whether you like Coupe SUVs or not is an entirely subjective matter, but there’s no denying the GLE 53 is a tech and spec showcase – some of the best Mercedes has to offer. If you can get past its relatively enormous dimensions and naturally compromised visibility – it’s even a hoot to drive.
The significant proportion of GLE consumers who are picking one of these over the regular version will be pleased with its many improvements. We’ll know more about how its price and specification lines up against primary rivals closer to its Australian launch date, so stay tuned.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.
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).
The GLE Coupe has improved so much in its looks it’s easy to see when it came to the second-generation GLE underpinnings, Benz had it planned from the beginning.
It looks mean, especially the 53 with its giant toothy grille. The stance is low and wide for an SUV, and I’m especially a fan of the much more resolved rear end.
It’s less bulbous and frumpy, more slick and menacing, rounded out nicely by the flick of a lip spoiler jutting out the rear.
You might think proportionally, the very idea of a coupe SUV is silly, and there’s no denying that, but then, you and I might not be the target audience.
That audience is someone looking for an avant-garde take on what a sports car actually looks like. They will be pleased – I’d say its even more resolved than BMW’s X Coupes and a little less science-fiction than Audi’s Q8. The incoming Coupe version of the Porsche Cayenne will be a real challenger.
The presence the GLE Coupe exudes extends to the inside, where there’s plenty of Mercedes wow factor. Level what you might at the brand’s use of silver fittings and flat dual-screen set-up, there’s no denying Benz offers an interior entirely unlike its competition.
The GLE has one of the best of the recent Benz interiors, too. I love the way the big dual-screen set-up is framed in a 'leather'-clad bay of vents.
I also like the real wood trim on our test car which runs across the dash and flows into the doors, and of course the wholly unnecessary vent-overload (becoming a Benz signature) pride of place in the centre of the dash.
It’s complemented by the tape-deck style silver switches for the climate controls which protrudes underneath.
The materials are great, with Artico trim running down the centre console, and across each doorcard. Almost every surface you’ll reasonably come into contact with is soft, and the commitment to real metals and wood is admirable.
Other highlights include the comfortable seats (with heating which extends into the armrests!) and AMG wheel which is flashy and aggressive, well suited to such a gratuitous vehicle.
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.
Naturally, the entire idea of shaving a solid bit of roof off of an SUV is going to compromise the amount of ‘practicality’ you get from such a large footprint.
Those compromises are not only there, but they are quite obvious. The sheer height of the GLE makes peering over the edge of the bonnet difficult for parking, and the sloped roofline causes the A-pillar to eat quite a bit of your field of vision.
As you might imagine, it’s genuinely difficult to see much out of the back of the GLE Coupe. I caught myself continually adjusting the rear vision mirror – as though somehow it would grant me more vision out of the letterbox rear window.
While front passengers get away with plenty of room, rear passengers are a little harder done by. This is again, largely due to the roof pillar, which eats into headroom and gives the cabin a claustrophobic feel.
Thankfully, legroom is fantastic (largely due to that massive GLE platform), the trim is all just as good as it is in the front seats, and the back of the centre console gets its own set of climate controls, adjustable air vents and USB-C power outlets.
I’d hardly say there’s an abundance of bottle holders for occupants, but there are a few. They aren’t big or packaged in ideal locations, but you’ll be able to get away with four 300ml containers in the front and four in the rear.
The boot has been re-worked from the GLE Coupe’s predecessor, there’s five extra litres on tap, for a total of 655 litres (VDA) – so it’s far from useless, but still down significantly from the full size GLE which has a massive 825L of space.
Benz has made the boot more useful, too, lowering the sill by 60mm for easier access.
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.
There’s no dancing around the fact that the GLE Coupe is a niche, gratuitous product, targeted at a well-off consumer.
We don’t know what the pricing will be for the Australian range yet – and we won’t for a few months. But what we do know is Mercedes-Benz will only bring two highly specified variants to our market for the launch.
Those two will be the AMG-tuned GLE 53 which we were able to test at the launch, and a slightly lesser specified GLE 450.
Expect tall pricing, north of the wagon bodied GLE 450 ($111,341) for the 450 Coupe and outgoing GLE 43 Coupe ($145,829) for the GLE 53 Coupe.
Standard features, as with the rest of the second-generation GLE range will be pretty good. We don’t know exactly what Australian-specified vehicles will get, but the GLE 53 as tested in Europe came with an extensive list of items.
You can expect all variants to get 20- to 22-inch alloys, electric tailgates, LED headlights, and Benz’ signature ‘Artico’ faux leather interior trim. The 53 also had a swish fully RGB adjustable interior ambient lighting suite and real wood in the dash. Very nice.
All GLE Coupes will have the impressive MBUX (I’m told it’s said “em bee you ex”, not “em bucks”) digital dash and multimedia suite, consisting of two 12.3-inch screens, one a digital dash, the other a multimedia screen.
The flashy setup also supports Apple CarPlay and Android auto as well as the usual connectivity via Bluetooth and packs several USB C outlets alongside Aux and USB 2.0. Our test 53 had a head-up display, too.
Mercedes’ built-in assistant (summoned by uttering 'Hey Mercedes') has perhaps the best native voice recognition on the market in terms of its accuracy and what it can do.
You can do things like adjust air conditioning, open the sunroof shade (oh yes, the GLE comes with a panoramic sunroof, too), and even find your specific music tracks via internet radio.
Then there’s the built in nav suite which is also one of the better ones on the market, featuring some very cool innovations.
The system will switch to the forward-facing camera when approaching an intersection and show you where to exit using augmented reality. Neat.
The 53’s system is also uniquely adjustable with AMG-specific themes and modes for the dash cluster, setting it apart from the lesser GLE 450 when it arrives.
It’s safe to assume there will be an extensive options list, including the 'E-Active Body Control' system (a $13,000 option on the wagon version) which uses cameras to detect road quality and optimize the air suspension system to suit. It also leans into corners. We’re keen to test it when it becomes available on the GLE 450.
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.
Australia will only get one engine in the GLE Coupe – a 3.0-litre 48-volt mild-hybrid in-line six-cylinder twin-turbo petrol.
There will be two states of tune. The 450 will be able to make use of 270kW/500Nm, while the AMG-spec GLE 53 we were able to drive at the launch has more power still (thanks to extra hybrid augmentation on the turbo) for a total of 320kW/520Nm.
For a quick comparison, the single-variant Q8 produces 250kW/500Nm from a twin-turbo V6, while the equivalent X6 – the M40i packs a 3.0-litre twin-turbo in-line six to make 250kW/450Nm.
The GLE 53 has a nine-speed auto transmission which is specially tuned by AMG to go with the expanded list of available drive modes. All Australian GLE Coupes will be all-wheel drive via a permanently active '4Matic+' 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.
The claimed combined cycle fuel consumption figure for the GLE 53 Coupe is 9.3L/100km, and while that’s not bad for something this heavy – keep in mind it’s an NEDC figure and not the widely-used WLTP figure so it could be a bit different by the time the GLE Coupe launches here.
Regardless, the fuel consumption is helped along by the abundance of ratios in the transmission and 48-volt mild-hybrid additions which help to remove inefficiencies from the drivetrain.
Our sweet but brief drive route in the Austrian Alps was not a fair reflection of fuel consumption, so we don’t have a real-world figure for you yet.
Expect the GLE 53 to require premium 98 RON unleaded petrol to fill its 65-litre fuel tank.
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).
The resurgence of the in-line six engine is a glorious thing, and it makes the GLE 53 quite a fun, if chunky, unit to drive.
Acceleration is urgent thanks to the pre-spooled first-stage turbo, and the transmission flicks through the gears like there’s nothing to it.
It’s perhaps not as 'smart' on the downshifts as competitor transmissions from Audi or Porsche, although Mercedes was keen to point out this will get better over time as the car’s computer 'learns' your driving characteristics.
Thankfully though, unless you’re in 'Eco' mode, the GLE 53 does a great job of letting you ride each gear out, giving you that signature in-line six sensation of an entire revolution range of relatively even torque distribution – a characteristic which Mercedes has gone to pains to perfect on a turbocharged engine.
This has the result of letting you bask in the sound for precious extra seconds.
While not as furious as preceding V8s – it is distinct. It’s refined and rich, although more subdued than you might have come to expect from vehicles wearing the Affalterbach badge.
I’m a fan. It’s an engine befitting a more refined sports machine than a garish statement.
The AMG suspension tune was great, too, keeping the massive Coupe truly under control in the corners, while soaking up bumps (which we’ll admit, there were few of on Austria’s immaculate roads).
It was interesting to read colleague Matt Campbell found the standard suspension less than impressive on the regular SUV-shaped variants, so we’ll see what the more basic set-up on the 450 is like at the Coupe’s launch.
I have no complaints about the steering, which proved to be responsive, smooth and accurate, while not erring too far on the heavy side, even in 'Sport' or 'Sport+' mode.
My main complaints lie with outward visibility and the sheer size of the GLE’s body. There were some nerve-wracking moments piloting it at speed around narrow streets with tall snow embankments encroaching.
And no matter how much I adjusted my seat and mirrors, the view out the back was particularly compromised.
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.
We don’t know exactly how Australian cars will be specified yet, but expect the two GLE Coupes to come with flagship active features like high-speed auto emergency braking (AEB), lane departure warning with lane keep assist, blind spot monitoring, rear and front cross traffic alert, adaptive cruise control, 360 degree parking sensors and cameras, fully auto LED headlights, semi-autonomous parking, and driver attention alert.
The GLE has nine airbags and dual ISOFIX child seat mounting points in the outer rear seats.
Regular wagon bodied GLE class vehicles have maximum five-star ANCAP safety ratings as of 2019, and we’ll update you when we hear more about the Coupe variants.
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.
Mercedes continues with its three-year/unlimited kilometre warranty which is frustratingly standard across European premium car manufacturers in Australia– particularly its primary competitors, Audi and BMW. We doubt this will change any time soon.
Like VW Group competitors, though, Mercedes is now bundling in service costs in packages which can be tacked on to finance. The GLE requires servicing once a year or every 15,000km – we’ll update you on the cost of the packages closer to the Coupe’s local launch.
