As far as the exterior goes, the new Cayenne won't deviate too far from the design template laid out by the current car with the greatest amount of familiarity at the front and around the sides.
Don't be fooled by the tail-light stickers on this prototype, the all-new Cayenne will sport a notably different rear cluster design that's rich in LEDs.
Big improvements are planned for the Cayenne's interior, with today's button heavy arrangement ditched in favour of a large, high resolution touchscreen in the centre of the dashboard.
Probably measuring 12 or 13 inches diagonally, the new screen is so large that Porsche's designers have been forced to relocate the central air vents to a spot underneath the display.
Most of the buttons, switches and dials that have survived the cull have been relocated to an area surrounding the new gear shifter. Right underneath the vents are a line controls for the audio system. Below this there are LCD displays and switches for the climate control system.
There are capacitive buttons for controlling the drivetrain and seat heating/ventilation to the left and right of the transmission selector. In this prototype there's a button labelled E-Power, indicating that we're looking a hybrid car.
Under the skin, the new Cayenne is expected to be based on the Volkswagen Group's MLB component kit for front- and all-wheel drive vehicles with longitudinal engines. The third-generation Cayenne will likely share many of its behind-the-scenes parts with the Audi Q7 and Bentley Bentayga crossovers.
Power should come courtesy of turbocharged V6 and V8 motors, with diesel options to cater for Europeans, and hybrid drivetrains that more appealing to American and Chinese tastes.
It's not clear when the new Cayenne will make its debut, but the earliest probable date will be at or around the time of the 2016 Paris motor show, which takes place at the beginning of October.
More likely, though, is a debut in 2017, with sales beginning in Australia in either late 2017 or early 2018.
