As an engineering showcase, the Cayenne Turbo S E-Hybrid ranks alongside supercars such as the 911 GT2 RS. However, its freakish breadth of capability on paper results in a less than perfectly rounded product on the road and ultimately consigns this wild Porsche to curiosity status – a car reserved only for those who really have to have the most extreme of everything.

There will be some for whom the electric range – and one should bank on no more than 16 miles, whatever the official claims – will be useful on a daily basis, but those miles will be undertaken in a fairly sedate nature, when this fastest but heaviest Cayenne’s necessarily firm and tightly controlled ride is completely unnecessary.

Technically impressive but fails to make a convincing case for itself

Equally, the electric portion of the powertrain contributes less in performance than it takes away from the handling and steering, which are both dulled. With 542bhp, if you really want to, you can still scare yourself witless in the regular Cayenne Turbo, and that car is a more natural, enjoyable and considerably cheaper point-to-point machine than this hugely capable, strangely likeable, undoubtedly wild but largely pointless hybrid.
