Chrysler’s luxury division Imperial always offered a quality alternative to Cadillac or Lincoln models. With powerful engines, plush interiors, and upscale styling, Imperials were always a good choice if you were looking for an exclusive sedan or a two-door coupe. However, by the late ’60s, it looked like Imperial was losing the race against competitors (via Hemmings).
1968 was the last year this brand featured a significantly different design than the rest of Chrysler’s lineup. In 1967 Imperial switched to unibody construction as a cost-cutting measure from Chrysler. This didn’t affect the comfort; it just saved some money during production. The 440 V8 was standard and delivered 350 HP.
