The Stutz IV-Porte was a series of limited production sedans introduced in 1971. The IV-Porte, meaning 'four doors,' was largely based on the Stutz Blackhawk, and was powered by a 5.7L V8 engine. Only around 50 examples of the IV-Porte, including variants known as the Duplex and Victoria, were believed to have built before production ended in 1985.
