The lofty cabin is typical of Porsche, with a widely adjustable driving position and an ambience that’s best described as ‘functional luxury’.
It isn’t quite as opulent as that of the highest-ranking Range Rover models or the Bentley Bentayga, but it’s impossible to complain about fit and finish, and the general air of composure and competence can be just as reassuring as quilted leather, walnut veneer and knurled aluminium. Perhaps more so given the lack of pretence.
As by far the most expensive car in the range, the Cayenne Turbo S E-Hybrid also enjoys a high level of standard equipment, including excellent adaptive sports seats and an Alcantara rooflining. Our testers also liked the double visors, which allow you to block the sun from two aspects – very useful. However, owners might still be disappointed to find they’re expected to pay extra for small luxuries such as a head-up display, ambient lighting, seat ventilation and four-zone climate control.
As a hybrid, this model also loses out on boot space. With the large battery pack positioned beneath the boot floor, luggage capacity falls from 772 to 645 litres, and to make matters worse, there is no underfloor compartment in which to store the sizable charging cable. This is still an amply spacious car and back-row passenger room is generous, even with the panoramic roof fitted, but an Audi Q7 or even the regular Cayenne Turbo is better suited to those likely to need all the available space.
If you simply have to have the 671bhp Turbo S E-Hybrid as your family conveyance, the model does at least, like every other Cayenne, feature Isofix points on the outer rear seats, and usefully the backrests are 40/20/40 split-folding, with a central storage tray and deployable armrest.
Porsche Cayenne infotainment and sat-nav
The Cayenne uses Porsche’s mostly excellent PCM system, which comprises a responsive and crisp 12.0in central touchscreen and digital roundels within the main instrument binnacle. The broad range of menus can be tricky to navigate at first but it soon becomes intuitive and the home page function lets you customise how information is presented. Our main complaint is that greasy fingerprints are unavoidable and quickly undermine the smart aesthetic.
For the range-topping Turbo S E-Hybrid, Bose’s 710W surround-sound system is fitted as standard and, in our experience, would be worth paying for even if it were not. Provision for device charging is also excellent, with two USB ports in the front centre console and two more in the rear compartment. The car also has three 12V power sockets, covering all areas of the cabin. One chink in the infotainment arsenal, however, is that Android Auto is unavailable.
