Official information about Porsche's Panamera sedan continues to trickle out of Stuttgart's front door, with the latest word being that the four-door gran turismo will incorporate a slate of new technologies that include a fuel-saving stop/start measure on models equipped with the company's fast-acting PDK dual-clutch gearbox. Stop/Start technology has been gaining traction in all segments of the European market as a way to lower C02 output and fuel bills, but it has yet to catch on in the States outside of use in hybrid models, so it will be interesting to see how well the technology is accepted. In addition to stop/start, the Cayman will feature a trick air suspension system that includes additional air volume available on demand and active aero on Panamera Turbo models.



Our top tech man, Sam Abuelsamid, is in Stuttgart as this is being written to get all of the engineering details, but for the moment, Porsche says their adaptive air suspension (standard on Turbo and optional on other models) is an "absolute innovation in automotive technology" in its ability to provide a greater breadth of range between comfort and sport, a claim made possible in part through the use of the company's lauded Porsche Active Suspension Management (PASM) system as well as optional Porsche Dynamic Chassis Control (PDCC), both being technologies we have sampled in other vehicles.



Porsche has a long history with active aerodynamics, and thanks to spy shots depicting a movable rear wing, we knew that the Panamera would also benefit from the technology. The automaker has now confirmed that the car will be fitted with a four-way rear spoiler on Turbo models.
