2018 Porsche Cayenne S review

By Daniel Gardner, 27 Oct 2017 First Drive

2018 Porsche Cayenne S review

Porsche’s once unlikely SUV is now three generations into convincing the skeptics

WHAT IS IT?

The third generation of Porsches large SUV and the latest iteration of the vehicle that debuted high-riders for the brand. Since the second-gen version the Cayenne has lost weight despite swelling in length and width, offers a bigger boot, increased performance and arguably wears the prettiest styling to date.


WHY WE
RE TESTING IT

Porsche may have forged its reputation and brand recognition through decades of slick sportscars, but its current cash cow in Australias unique market is an SUV. The new Porsche Cayenne might not have quite the appeal or price to knock its Macan little sister off its perch but it certainly does have the potential to add a hefty chunk of volume if Porsche has got the recipe right once again.

With more choice than ever in the luxury and performance large SUV market, the Porsche cant afford to rest on its laurels and must bring a significant new offering to remain relevant in a fiercely competitive segment.


THE WHEELS VERDICT

There is no hiding the fact that the new Cayenne S is still two tonnes of metal despite an impressive weight-loss program, but Porsche has not tried to engineer the third-gen version to conceal its heft.

Instead, the recipe of traditional chassis tuning, prodigious power delivery and a dose of some clever innovations has imparted an honest mechanical feel to the big SUVs manner on and off road that embraces its size - and it works.

Australian customers will likely be asked to put their hand in their pocket for the most exciting features such as active roof spoiler, rear steering, air suspension and roll stabilisation, but if they do, the pricier result is among the most enjoyable large SUVs to pilot while only minimally compromising on practicality.


PLUS
: Potent V6 power; rewarding driving dynamics; sophisticated looks and interior.

MINUS: No third row seating; nav gremlin; most exciting features are optional

THE WHEELS REVIEW

I CAN still remember wincing when Porsche announced the most un-Porsche like addition to its Stuttgart stable the Cayenne. How could a lumbering all-wheel drive possibly uphold the Porsche mantra, I cursed. But that was 15 years ago and, in the meantime, the large SUV has categorically silenced its naysayers.

The gen-one Cayenne might have looked like a kids 911 pedal car scaled up for adults to play with, but it was one of the first to flirt with the idea that two tonnes of off-road-capable metal can be fast and fun to drive. Its replacement stepped up dynamics and performance another rung, and wrapped the compelling package up in a shell that someone other than its mother could love.

But its nearly 2018 and while many sports and luxury car manufacturers initially resisted the allure of a burgeoning soft-roader market, virtually all have now given in, creating more competition for the Cayenne than it has ever had to face.


The third-generation car arrives at a knife fight with quite the armoury. The all-new Cayenne has gone on a crash diet thanks to the Volkswagen Group
s MLB Evo modular platform, it features an initial range of engines that doesnt appear to include a fizzer, and just get a load of those looks.

The early signs are good then, and a first blast behind the wheel across the stunning island of Crete didnt disappoint. Unlike the weathered Greek scenery that is punctuated with unfinished, often dilapidated buildings and beaten, abandoned cars, Porsches new Cayenne range appears  polished, refined and complete.

While a 404kW Turbo flagship and base 250kW Cayenne will bookend the initial range when it arrives in early 2018, I grabbed the keys to the 324kW Cayenne S and was greeted by a waxy-leather-upholstered front row of seats that offer an excellent driving position and a second row that feels almost as supportive.


The cabin is clearly tailored for four-plus-one and in this segment, the lack of a third row and seven seats is likely to deter some customers with large families, although the new version provides some recompense with an extra 100 litres of boot space.

The Cayenne S is a wholly cosseting place to cover kilometres, with an eerily silent and smooth ride even over the somewhat agricultural local roads. The interiors been tidied, the most obvious beneficiary being the simplified fascia design. Where the previous versions dash was littered with a multitude of switches and, even worse, blanks for lower-spec cars, the new Cayenne uses solid-state panels with haptic switches and a massive 12.3-inch screen.


With the exception of one occasion when the navigation froze, rebooted and forgot all our saved destinations, the result is a tidy and classy system that doesn
t sacrifice intuitive operation.

But staring at a touchscreen is to waste the spectacular Crete road vista, which dives and twists from chilly mountain towns that could have been lifted from a remote Afghan village and provides a solid workout for the Porsches dynamics.


While the majority of all Cayennes sold in Australia will likely never see any terrain more challenging than a damp carpark, we had the opportunity to take the big Porsche on a brief wilderness adventure that demonstrated that its off-road driving mode can take the Cayenne further than most will dare. More relevantly, its on-road manners are what really impress.

With the drive mode switch left in normal mode, the Cayenne favours a safer driving manner, leaning into understeer on slippery tight turns and a more placid map for throttle response and gear changes. But with the dial spun round to Sport or Sport Plus, the variable four-wheel drive system favours the rear axle. Rear axle steering is also offered (as an option) for the first time on a Cayenne as are mixed-width tyres, the rubber on this car being 20mm wider at the rear than the front.


Turn into a faster corner with a little more pace, and the Cayenne settles in with impressive grip, body control and resistance to roll thanks to electromechanical roll stabilisation.

Its possible to actually feel the clever transmission moving torque around under the Cayenne as the accelerator position is altered in longer, faster corners. A fluid, direct steering set-up also imparts confidence that the Cayenne will keep its bulk out of the autumn thistles.

Tractable power and torque complete the dynamic Cayenne S package with a 2.9-litre twin-turbo V6 providing the punch. Peak grunt of 550Nm is in at 1800rpm for eager pace off the mark, but the slick bent-six pulls hard all the way to a maximum power output of 324kW at 6600rpm. The engines closely related to that found in the latest Audi RS4, so even a midrange Cayenne purchase nets you a serious powerplant.


With the V6 stacking fewer kilos over the front axle, the Cayenne S has a more confident, lighter feel for a driving enthusiast when compared with other high performance large SUVs, including the Audi SQ7 which carries a huge V8 diesel in its nose.

Acceleration is strong (4.9 seconds to 100km/h, claims Porsche) and would leave Cayenne S customers wanting little compared with the Turbos V8 might, particularly as the V6 brings its own satisfying low-rev soundtrack and high-end holler.

Slowing down doesnt bother the Porsche either, thanks to its new optional mirror-finish tungsten-coated disc package that initially feels a little like  cold carbon ceramic brakes but builds with firm pedal feel and progressive clamping right up to ABS intervention.

While the notion of any large SUV wearing a pedigree sportscar producers badge will probably never sit entirely comfortably with some, the Porsche Cayenne S is now three generations into convincing sceptics that heavy doesnt have to equal slow, ample practicality doesnt amount to dull, and big can be beautiful.
