The Cayenne Turbo makes as much as 1139 horsepower to become the most powerful Porsche to date, and it can rip off a 60-mph run in just 2.4 seconds. All models get 800-volt architecture with 108 kWh of net capacity, and the battery is integrated into the structure for less overall height and weight. This is the fourth generation of the Cayenne, which will be sold alongside the third generation of the internal-combustion version. | Car and Driver
