The Panamera comes with the Porsche Traction Management (PTM), which is Porsche's name for its fully-controlled, four-wheel drive system. PTM is standard on both the Panamera 4S and the Panamera Turbo. Optional Sports Chrono Packages include a Sport Plus button, which has tighter damping and air springs, and lowers the car body by 25 mm (1.0 in).
