Conner Avenue Assembly is a Chrysler automobile factory in Detroit, Michigan. The factory opened in 1966 and was purchased by Chrysler in 1995 for the Dodge Viper and Plymouth Prowler. Viper production moved from New Mack Assembly in October 1995 and Prowler production started in May 1997. The Viper's V10 engine was originally built at Mound Road Engine but moved to Conner Avenue in May 2001. The facility had been out of use since 2010, when Viper production temporarily ceased, however the plant resumed operations in late 2012 to build the Viper.
