Porsche's Leipzig plant will build two instead of one unit of the super-sports car per day from April.
Porsche says the production boost will not result in shorter waiting times for customers.
A buyer who orders a Carrera GT today will get the car at the beginning of 2006 at the earliest, said Siegfried Buelow, managing director at the Porsche Leipzig GmbH.
That's because 1,000 units of the special edition, which is limited to 1,500, are already sold.
The cars are dispatched from the plant strictly according to who ordered first.
Buelow told Automobilwoche that more staff are being employed at the plant.
The number of workers on the GT assembly line will rise to 70 by April.
Porsche's cost cutting program is going to plan, say company executives.
Porsche boss Wendelin Wiedeking recently announced that Porsche's manufacturing costs should drop by as least 5 percent this year.
The focus of the savings program is the Cayenne, which is also being built in Leipzig.
