For 1959, the Ambassador received a revised grille, side trim, and redesigned rear door skins that swept into the tailfins instead of terminating at the C-pillar. Scotchlite reflectors were also added to the rear of the tailfins to increase visibility at night. Front and rear bumpers were over 20% thicker and featured recessed center sections to protect license plates. Adjustable headrests were now available as an option for the front seats, an industry first. AMC touted the added comfort the headrests provided, as well as their potential for reducing whiplash injuries in the event of a rear-end collision. Other changes included the activation of the starter through the neutral pushbutton (on automatic transmission-equipped cars), and the addition of an optional "Powr-Saver" engine fan, which featured a fluid-filled clutch for quieter high-speed operation.
