Porsche Cars North America has moved into its new headquarters near Hartsfield-Jackson International Airport.

Employees moved into the new building Tuesday, relocating from their old headquarters in Sandy Springs, said Porsche Cars North America general counsel Joe Folz. Roughly 300 are now in the new facility by the airport off I-75, he said.

A test track that is part of the facility isn’t yet complete, but is expected to begin operations by early April. When it is up and running, the headquarters with its customer experience center will have a total of about 450 employees, Folz said.
