Porsche launched the third-generation Cayenne in 2018 last year. Now it is adding S and Turbo versions in North America.Standing side-by-side with the older mode, the new Cayenne is more hunkered down. It is 25 mm lower, 29 mm wider and 63 mm longer. It is also 65 kilos lighter despite a raft of new standard equipment and additional sound deadening.
The Cayenne S has a new 2.9-litre twin-turbo V6 producing 434-horsepower and 406 lb.-ft. of torque. It replaces the 420-horsepower, 3.6-litre unit used previously.
The Turbo model gets a 4.0-litre twin turbo V8 used in the Panamera. It puts out 541-horsepower and 568 lb.-ft. of torque. It can propel the Cayenne from rest to 100 km/h in less than four seconds. The outgoing Turbo had a 4.8-litre eight.
