Over the 20th anniversary of the Cayenne SUV, Porsche highlighted how it safeguarded privacy during its development. The company emphasized that a critical phase of the project took place not at Weissach, its renowned engineering hub, but at a former computer assembly facility in Hemmingen, Germany. The choice of location underscored a commitment to secure, discreet progress during a pivotal period of expansion.
Inside the Hemmingen site, no Porsche logo appeared on the grounds. A team of about 260 engineers operated there, working within a three story building that was protected by a sturdy fence and mirrored windows. Those arriving to contribute to the Cayenne program stored their vehicles in a covered garage, reinforcing the effort to maintain confidentiality around the project.
The Cayenne SUV entered the market in 2002, and during its development the initiative carried the codename Colorado. This phase reflected Porsche’s strategic approach to scaling production while preserving rigorous privacy standards, even when the work shifted away from established, high-profile centers.
Earlier, there were discussions about collaboration with GM on new vehicle concepts, including the potential for an electric SUV, the Hummer EV.
