The SUV coupe is a curious species. Less roomy and practical than a traditional, upright SUV, yet less dynamic and stylish than a coupe, it seems to be the worst of all worlds. Still, nobody buys a Porsche for entirely rational reasons – especially not one that produces 1,156 horsepower. No, that isn’t a typo. The new (deep breath) Porsche Cayenne Turbo Coupe Electric isn’t just a bit of a mouthful, it’s also the most powerful production Porsche ever made.
