The Zephyr/Zodiac Mark III shared some of its mechanical components, as well as the basic chassis design, with the Mark II, but had a stronger overall body construction.
The exterior was designed by Canadian Roy Brown who also designed the Edsel and the Cortina, though the rear of the body was inspired by a design proposal by Frua.
Unlike the Zephyr 4, the Zephyr 6 had a full width grille including the headlight surrounds.
