The 2018 Cayenne won’t be around for long: a brand-new 2019 model is arriving in the summer of 2018 and will feature the Panamera’s aluminum-rich platform. There are three available engines: a 340-horsepower, turbocharged 3.0L V6, a 440-horsepower, twin-turbo 2.9L V6 as well as a twin-turbo, 4.8L V8 good for 550 horsepower in the Turbo and 570 in the Turbo S. Porsche estimates that it will take the Cayenne 18 years to reach one million units sold—a figure it took the 911 53 years to reach.
