Porsche Cayenne VS Bentley Bentayga
- Magnificent twin-turbo petrol V8
- Superbly comfortable
- Surprisingly dynamic for its size
- A little awkward looking
- Low on standard advanced safety equipment
- Boot is smaller compared to rivals
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|
When Bentley revealed its Bentayga in 2015 the British brand called it “the fastest, most powerful, most luxurious, and most exclusive SUV in the world."
See, that first Bentayga packed a W12 engine, but the SUV we have here was introduced in 2018 with a twin-turbo petrol V8 and a reduced price tag.
So how does this more affordable and less powerful Bentayga stack up to Bentley's lofty ambitions?
Well you’ve come to the right place, because along with speed, power, luxury and exclusivity I can also talk about the Bentayga V8’s other attributes, such as what it’s like to park, drop children off at school in, do the shopping in and even go through a 'drive thru' in.
Yes, the Bentley Bentayga V8 came to live with my family for a week and as with any house guest you quickly find out what’s great about them… and then there are those times you walk in on them not looking their best.
|Engine Type||4.0L turbo|
|Fuel Type||Premium Unleaded Petrol|
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.
The Bentayga is Bentley’s first attempt at an SUV and the Bentayga V8 is a more recent addition to the line-up that provides an alternative to the W12, hybrid and diesel models.
There’s no doubt the Bentayga V8 delivers an exceptionally good driving experience from its power and athleticism to the serene cabin and comfortable ride.
Where the Bentley Bentayga V8 appears to be lacking is in cabin technology which compared to other luxury SUVs is becoming outdated, and in standard advanced safety equipment. We’d expect this to be addressed in future revisions of the SUV.
Does the Bentayga fit the ultra-luxury SUV bill? Tell us what you think in the comments section 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).
The Bentayga is unmistakably a Bentley, but I have my doubts whether this first attempt by the British brand to build an SUV has been a design success.
To me, the rear three-quarter view is its best angle with those trademark rear haunches, but front-on reveals an overbite I can’t ‘unsee’.
But then again perhaps I’m the one with bad taste, I mean I think Lamborghini's Urus SUV, which uses the same MLB Evo platform, is a work of art in its design, staying faithful to the sports cars in the family, while acquiring a brave look of its own.
I also found the interior of the Bentayga V8 disappointing. Not in terms of overall craftsmanship but rather its outdated technology and plain styling.
The 8.0-inch screen is almost identical to the one used in the Volkswagen Golf in 2016. But the Golf received its Mk 7.5 update in 2017 and with it a stunning touchscreen which hasn't made it into the Bentayga yet.
The steering wheel, too, has identical switchgear to the $42K Audi A3 I reviewed two weeks ago and you can add the indicator and wiper stalks into that mix as well.
While the fit and finish of the upholstery was outstanding, there was a lack of interior refinement in some places. For example, the cupholders, had rough and sharp plastic edges, the gear shifter was also plastic and felt flimsy, while the fold-down armrest in the back seats also lacked refinement in the way it was constructed and lowered without damping.
At just over 5.1m long, 2.2m wide (including the wing mirrors) and a little over 1.7m tall the Bentayga is big but it’s the same length and width as the Urus, and a bit taller. The Bentayga’s wheelbase is only 7.0mm shorter than the Urus’s at 2995mm.
The Bentayga isn’t the longest of the Bentleys, that’s for sure. The Mulsanne is 5.6m end-to- end and the Flying Spur is 5.3m in length. So, the Bentayga V8 is almost ‘fun-size’ in Bentley terms, even though it’s large.
The Bentayga is made in the United Kingdom at Bentley’s home (since 1946) in Crewe.
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.
The Bentayga V8 may be an SUV, but that doesn’t immediately make it a god of practicality. While roomy up front for the driver and co-pilot, the rear seating is not exactly limo-like, although at 191cm tall I can sit with about 100mm of space. Headroom is slightly limited by the edges of the panoramic sunroof for rear riders, too.
Storage in the cabin is adequate with two cupholders and small door pockets in the back, and another two cupholders and larger door pockets in the front. There’s also a shallow centre console storage bin and two wells for loose items in front of it.
The Bentayga V8’s boot with the rear seats in place has a cargo capacity of 484 litres – that’s measured to the cargo cover, but to the roof its 589 litres.
That boot space is still smaller than the Lamborghini Urus’s 616 litres and there’s much less boot space than the Audi Q7 and Cayenne which both have 770 litres measured to the roof, too.
Making life easier is the load-height lowering system which is operated with a button located in the boot.
The tailgate is powered, but the kick-open function (standard on say an Audi Q5) is an option you’ll have to pay for on the Bentayga.
As for power outlets and charging, the Bentayga’s falling out-of-date here, too. There is no wireless charger for phones, but there are two USB ports up front and three 12-volt outlets (one in the front and two in the rear row) on-board.
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.
That’s the question those who can’t afford a Bentley Bentayga V8 want to know the answer to, and the one that those who can don’t ask.
I’m in the first group, so I can tell you the Bentley Bentayga V8 has a list price of $334,700. Our car had $87,412 in options which we’ll take a look at, but all up including the on-road costs, our test car had a price of $454,918.
Standard features inside include leather upholstery in a choice of five colours, 'Dark Fiddleback Eucalyptus' veneer trim, a three-spoke leather clad steering wheel, ‘B’ foot pedals, Bentley embossed treadplates, an 8.0-inch touchscreen with Apple CarPlay and Android Auto, sat nav, a 10-speaker stereo, CD player, digital radio, four-zone climate control and shifting paddles.
Exterior standard features include 21-inch wheels, black painted brake calipers, air suspension with four height settings, a choice of seven paint colours, gloss black radiator grille, black lower bumper grille, LED headlights and LED tail-lights, twin quad-exhaust and a panoramic sun roof.
Our car was fitted with options galore which is common in vehicles loaned to the media. Car companies often use these cars to showcase available options rather than represent a typical customer specification.
There’s the 'Artica White' paint from the bespoke Mulliner range costing $14,536; 'our' car's 22-inch wheels weigh in at $9999, as do the fixed side steps; the tow bar and brake controller (with Audi Q7 badging, see the images) is $6989; body coloured lower bodywork is $2781 and LED puddle lights are $2116.
Then there’s the acoustic glazing for $2667, front seats with the 'Comfort Specification' for $7422 and then $8080 for the 'Hot Spur' main hide and 'Beluga' secondary hide leather upholstery, the $3825 piano black veneer trim and if you want the Bentley logo embroidered into the headrests (as per our car) it costs $1387.
Does it represent good value for the price? Not by regular standards, but Bentleys are anything but regular cars, and those that buy them tend not to look at prices.
But, as I do with every car I review (whether it costs $30,000 or $300,000), I ask the manufacturer for a list of options fitted to the test car and the as-tested pricing, and I always include those options and their costs in my review.
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.
The scores I’ve awarded to the Bentayga V8 so far haven’t been impressive, but now we come to the twin-turbo 4.0-litre V8.
Derived from the same unit found in the Audi RS6 this turbo-petrol V8 makes 404kW/770Nm. That’s enough grunt to get this 2.4 tonne beast from parked in your garage to 100km/h in 4.5 seconds, provided your driveway is at least 163.04m long, which for some owners would be entirely possible.
That’s not as quick as the Urus which can do it in 3.6 seconds, but while the Lamborghini shares the same engine it’s tuned to make 478kW/850Nm and that SUV is about 200 kilos lighter.
Shifting gears wonderfully in the Bentayga V8 is an eight-speed automatic which suits the Bentley better with its seamless but not-in-a-huge-hurry gear swaps than the same unit in the Urus.
While there are those who think a W12, as found in the first Bentayga, is more in line with Bentley’s ethos, I think this V8 is superb in its power delivery and sounds subtle but magnificent.
The braked towing capacity of the Bentley Bentayga is 3500kg.
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.
A 4.0-litre twin-turbo petrol V8 pushing a 2.4-tonne SUV loaded up with people and possibly towing a horse float is going to want to be fed fuel – lots of fuel.
And that’s even if engine has cylinder deactivation like the one in the Bentayga V8 which can cut out four of the eight when not under load.
Officially, combined fuel consumption for the Bentayga V8 is 11.4L/100km, but after 112km of fuel testing on a combination of motorways, suburban and city roads I measured 21.1L/100km at the petrol pump.
I’m not surprised. For most of that I was in Sport mode or in the traffic, or in both at the same time.
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).
Comfortable and (believe it or not) athletic, sums it up. And the only thing stopping me from throwing in another word such as effortless is the forward visibility, which is what I noticed the moment I steered it out of the dealership and into the traffic.
But first let me give you the comfortable and athletic good news. The Bentayga felt nothing like it looked to drive – my eyes told me it should be more sumo wrestler than ninja to steer but they were wrong.
Despite the hulking dimensions and not insignificant weight, the Bentayga V8 felt surprisingly lithe with great handling for an SUV this size.
That the Urus, which I test drove a few weeks beforehand, also felt athletic seemed less a surprise in that the styling suggested it was agile and quick.
Thing is it shouldn’t be a surprise given the Urus and Bentley share the same MLB EVO platform.
Four standard drive modes let me change the character of the Bentayga V8 from 'Comfort' to 'Sport'. There’s also a ‘B’ mode which is a mix of throttle response, suspension and steering setting which Bentley nominates as the best for all-round driving conditions. Or you can ‘build-you-own’ drive mode in the 'Custom' setting.
Keeping the comfort mode on makes the ride composed and supple. Self-levelling air suspension with continuous damping is standard but flick the dial to Sport and the suspension firms, but not to the point where the ride is compromised.
I spent most of my almost 200 kilometres testing it in Sport mode which did nothing to help fuel economy but made my ears happy with the V8 burble.
Now, about that forward visibility. The design of the Bentayga’s nose is the cause of my issue here; specifically the way the wheel guards are stepped down out of view from the bonnet.
All I knew was that I was about 100mm wider that it looked from the driver’s seat – I don’t like that kind of guess work when piloting half a million dollars down a narrow street or car park. As you’ll see in the video I came up with a solution to the issue.
I’m not going to let that nose get in the way of a poor score, however. Besides owners will get used to it after a while.
Aside from that, the Bentayga was quite easy to parallel park with light steering and good rearward visibility and large wing mirrors, while multi storey shopping centre car parks were also surprisingly fuss free to steering through – this is after all not an overly long large SUV.
There was one ‘drive thru’ excursion and again I’m happy to report I emerged with hamburgers and without scratches at the other end.
So, I’m happy to throw effortless in there after all and you can add serene – that cabin felt bank vault-like insulated from the outside world. Don’t ask me how I know that.
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.
The Bentayga V8 has not been assessed by ANCAP testing but being based on the same platform as the five-star rated Audi Q7 I have no reason to suspect the Bentley would perform any differently and not be safe from a structural perspective.
We’re tough on budget cars that don’t come standard with AEB and likewise on high-end vehicles, and the Bentley Bentayga V8 doesn’t escape here.
AEB is not standard on the Bentayga V8 and if you want other forms of advanced safety equipment such as lane keeping assistance, adaptive cruise control and rear cross traffic alert you’ll have to option them across two packages – the 'City Specification' for $12,042 and the 'Touring Specification' which was fitted to our car for $16,402.
The Touring specification adds adaptive cruise, lane keeping assistance, AEB, Night Vision and a head-up display.
For child seats you’ll find two ISOFIX points and two top tether anchor points across the second row.
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.
