What is it?
This is, officially speaking, the most environmentally friendly Porsche SUV on sale. Which is a bit like saying “the least threatening nuclear warhead” or “the easiest to park aircraft carrier”. Nevertheless, that’s how the new Cayenne E-Hybrid fits into the range.
It’s been just over a decade since Porsche first toyed with hybridising its flagship SUV. Skip forward two generations and the official economy figure has more than doubled, thanks to the use of plug-in hybrid tech. Today’s petrol-electric Cayenne claims up to 88mpg depending on spec - a figure which of course depends on you keeping the battery juiced up wherever possible.
For the first-gen Cayenne, hybrid tech offered up a bit of a USP in the market of premium 4x4s. Now it’s anything but, with all the main competitors - Audi, Mercedes, BMW and Land Rover - offering some sort of plug-in offering.
But Porsche has had time to perfect the art for the third-generation. Ditching the old Cayenne S E-Hybrid’s supercharged V6 in favour of a turbocharged 3.0-litre lump mated to a 30% more powerful rear-mounted electric motor pushes up combined power from 410bhp to 456bhp, while torque is up 81lb ft. Nearly a full second has been shaved off the 0-62mph time as a result.
