The 2008 Los Angeles Auto Show saw the unveiling of the facelifted 2009 Porsche Boxster and Cayman models (click here for photos and details). In true Porsche fashion, both cars feature significant mechanical upgrades as well as near invisible cosmetic changes. Highlights include the more powerful yet also more fuel efficient direct-injection boxer engines and the option of Porsche's new PDK double-clutch sequential-shift gearbox. Sales of the revised Cayman coupe and Boxster Roadster will begin in early 2009 but until then, skip the jump to get a taste of both vehicles in the videos that follow.
