The eleventh generation of the Ford Thunderbird (internally codenamed M205) is a two-seat convertible manufactured and marketed by Ford from 2001 to 2005 for model years 2002 through 2005. It followed a five-year hiatus of the Thunderbird after the 1997 discontinuation of its tenth generation. The eleventh generation reach a production of just under 70,000 over four model years. Critics attributed the lackluster sales to poor marketing.
