ATLANTA - Porsche Cars North America says it plans to consolidate several of its U.S. operations in a new complex being planned in Atlanta, where it already has headquarters.

The company said Thursday the complex will include a road course and be located near Atlanta's airport.

Other U.S. operations moving to Atlanta include Porsche Financial Services Inc. and Porsche Business Services Inc., both currently located in Lisle, Ill.

Porsche says the complex will include office facilities for a workforce that will eventually number 400 employees, including a technical service and training centre. Its website says about 180 are currently employed at its Atlanta hub.

Groundbreaking is planned for this fall, with opening scheduled for the second half of 2013.
