Porsche Cayenne review
The Porsche Cayenne may anger purists, but it's the most versatile Porsche you can buy
The Porsche Cayenne is no longer controversial - lots of manufacturers make sporty 4x4s. That means we can at last focus on not on the logic behind its existence, but just how talented this amazing vehicle is. The classy cabin, superb handling and strong refinement have made it a real class favourite, while the V8-engined Cayenne S Diesel offers just the sort of performance you’d expect from a Porsche. It uses the same platform as the VW Touareg, and it also shares some of that car’s less powerful engine options. The Hybrid and new V8-powered S Diesel models are particular highlights of the Porsche Cayenne range, and although most owners will never discover it, the Cayenne is equally mighty on the road as it is on it. On the road it is almost untouchable, and would give some genuine sports cars a real run for their money – especially in 500bhp Cayenne Turbo form, where it can complete the 0-60mph dash in only 4.4 seconds.
Our choice: Cayenne S Diesel
Now into its second generation, the Cayenne’s once-controversial styling has matured into a smart and well proportioned shape. In fact, compared to the BMW X5 and Range Rover Sport, the Porsche looks much less ostentatious. Yet while the Cayenne doesn’t shout about its performance credentials on the outside, there’s no doubting its sporting intentions inside. The first-class driver-focused layout wraps around you, giving the cabin a sports car feel, while the quality of materials is peerless. Like the rest of the Porsche range, the Cayenne benefits from a great interior that is impeccably well put together with beautifully made switches and a raised cockpit-style dashboard that is inspired by the Porsche Panamera saloon.
From the driver’s seat the Porsche Cayenne feels more like a sports car than an SUV – the low-slung driving position and high transmission tunnel are similar to that in the Panamera saloon. On the move the feeling continues, with impressive straight-line performance, even with the diesel, and lots of grip and composure through the bends. Chunky C-pillars do affect visibility, but the Cayenne’s agility is superior to the BMW X5 and Mercedes ML and it's easier to manoeuvre. Body control is good especially on the optional air suspension and there’s plenty of grip, yet the Porsche is almost as relaxing and refined as the Range Rover Sport. Opt for the V8 Turbo and you’ll accelerate faster than many of the firm’s sports cars, while the Hybrid model can still crack the 0-60mph dash in just over six seconds – not bad for an eco-friendly model. Purists might have sneered at the idea of a diesel Porsche, but any concerns about the engine are dispelled as soon as you turn the key of the Cayenne S Diesel. The combination of 382bhp, a mighty 850Nm of torque and a sporty throttle response means the Porsche has a never-ending wave of thrust. All models come with a Tiptronic automatic gearbox that is smooth and responsive in automatic mode and mostly on-the-pace when you're using the paddleshifters too.
Should you choose to take your Cayenne off-road, you'll be astounded at how capable it is. the hill-descent contol and locking differentials mean it's adept at crossing very harsh terrain, although the wading depth is beaten by Land Rover's rivals. You'll need the adaptive air suspension too, whicvh can raise the ride height for tricky sections. Even the flagship Turbo likes to splash about off-piste, but for us the pick of the range remains the Cayenne S Diesel - which uses an incredible sounding 4.2-litre V8 that is just as fast in-gear as the Turbo but much more economical than its petrol counterpart.
Like other Porsche models the Cayenne has never been tested by Euro NCAP, but all models are fitted with six airbags, Isofix child seat mountings, Porsche Active Stability Management (PASM) and parking sensors. So far there’s been no recalls for the Porsche Cayenne. It is a proven product, while the 4.2-litre V8 diesel engine is borrowed from Audi, albeit with unique internals. The Cayenne is also equipped with a good range of safety kit as standard, and there’s a raft of options, while Porsche ranked 13th in our Driver Power 2013 customer satisfaction survey.
WIth a 670-litre boot, the Porsche trumps the BMW X5 for seats-in-place luggage space, but a chunky transmission tunnel and a flat base make the middle seat a little uncomfortable. Like the Range Rover, the rear bench slides, while up front the driving position is superb and there’s loads of cabin stowage. It’s not that roomy in the cabin though, the high transmission tunnel making it a much more intimate space than inside its rivals. Admittedly the rear seats slide back and forth, altering the amount of room available for rear passengers and luggage, and the boot space is well trimmed, as you’d expect from any Porsche.
Economy and efficiency varies greatly depending on what model you choose, and top of the tree for non-hybrid Cayennes is the V6 diesel, which can return 39.2mpg. At the other end of the scale is the V8 Turbo, which manages 24.6mpg but chucks out 270g/km of CO2 – 81g/km more than the Porsche Cayenne Diesel. Costing exactly the same to buy as a Cayenne S Diesel, the new S E-Hybrid is by far the most economical. Because it can run for up to 30 miles on e-power alone, it achieves combined fuel economy of some 80mpg, and emits a supermini-sized 79g/km.
Compared to the BMW X5, and the VW Touareg especially, the Porsche Cayenne is more expensive, but it generally feels more special than any of its rivals. Like the rest of the Porsche range there are many options and personalisation choices, but these are usually expensive and can quickly send the cost of the Cayenne spiralling out of control. Strong residual values of 57.2 per cent over three years are a plus for private buyers.
Beware the options list too. Cayenne spec levels are very stingy, with none of the models offering sat-nav, Bluetooth or DAB radio as standard. This unacceptable lack of equipment is even more annoying when you consider all of those items are standard fare in the BMW X5 and Range Rover Sport. Speccing up your Cayenne to match these talented cars can get very expensive.
