The company's Leipzig plant received 20,000 visitors last year. Around 30,000 visitors are expected this year.
Klaus Zellmer, Porsche Leipzig GmbH's marketing director, said visitors include buyers who come to pick up their cars, curious local residents and spectators who attend one of the events staged at the plant.
"Anyone who comes to collect a car, attend an event or as a visitor is infected with the Porsche virus," he said.
The plant was opened 20 months ago to manufacture the Cayenne and Carrera GT.
Nearly 50 percent of German Porsche buyers collect their Cayennes and GTs in Leipzig.
Customers who chose the option "collection at the plant" when placing an order can pay an extra 690 euros for a five-hour, Porsche-themed entertainment program.
The program includes a circuit around the plant's 3.75-kilomter test track with a professional driving instructor. Cayenne buyers are also taken on a 6-kilomter off-road course.
Customers from North America who want to collect their car from the factory can drive their new car across Europe before it is shipped across the Atlantic.
