What is the difference between the Porsche Cayenne Base and the Black Edition?

Both variants use the same 3.0-litre turbo-petrol V6 engine, 8-speed automatic gearbox and AWD system. Performance figures are also identical.
The Black Edition mainly adds styling and equipment, including:

Adaptive air suspension with PASM

21-inch RS Spyder Design alloy wheels

Sport Chrono Package

18-way adaptive sport seats with memory

BOSE 14-speaker sound system

Panoramic glass roof

Black exterior styling elements

Darkened Matrix LED headlights

If these features are important to you, the Black Edition offers better value than adding them individually to the base model.
