Porsche has a long history dating back to 1931. It struggled financially during the 2008 crisis but was acquired by Volkswagen in 2010. Volkswagen's plan is to fully integrate Porsche by 2011, which risks diluting the brand. Porsche faces challenges retaining executives and customers as it expands its product line under Volkswagen ownership. It must also address tightening emissions regulations that threaten its US market. Porsche will help Volkswagen achieve its strategic goal of becoming the top automaker by 2018 through technology sharing and diversification, but maintaining its brand strength and customer loyalty will be critical.
