What is it?
The news that Porsche has, at the very least, put all its diesel programmes on hold makes this new Cayenne Hybrid a car that's more important than usual.
If you want a Cayenne but care about taxation and running costs, this is the one you’re going to have to buy. Porsche denies that diesels have been ruled out of all future models, but it does say the entire strategy is "under review". So don’t hold your breath.
You’d have thought Porsche would just transfer the powertrain from the Panamera hybrid straight over; it fits and comes with four-wheel drive as standard. But no, the hybrid powertrains in a Panamera and this Cayenne are related but by no means the same. As we shall see, this brings news both good and bad for this luxury SUV.
