Subaru launched the third generation Japanese and world-market Legacy in June 1998, while the North American model was introduced in 2000. In all markets except for the United States, production lasted through 2002, with a limited production Blitzen model sold mid-cycle under the 2003 model year in Japan. Production in the United States lasted through 2004.
The Blitzen model was the result of a collaboration with Porsche Design, and featured many unique parts and paint schemes. The wheels, body kit, and interior were all designed by Porsche Design. It also featured an implementation of the Porsche Tiptronic automatic gearbox, the first use of sequential-shifting on a production Subaru model.
