The Newport was a name used by Chrysler for both a hardtop body designation and also for its lowest priced model between 1961 and 1981. Chrysler first used the Newport name on a 1940 show car, of which five vehicles were produced.

Fourth generation 1973-1978
The Newport was redesigned for the 1974 model year, along with all other full-size C-body cars. This generation shed the sweeping "fuselage" styling, in favor of more crisper, slab-sided styling. Despite losing several inches in length, 1974-1978 Newports were some of the heaviest cars ever produced by Chrysler. Their introduction coincided with the 1973 OPEC oil embargo, and sales of all full-size cars plummeted. The Chrysler Corporation was especially hit hard, as no smaller cars were sold under the Chrysler brand.
Production of the C-body Newport ended in 1978, along with the Chrysler New Yorker. Related Dodge and Plymouth C-body cars, as well as C-body Chrysler Town & Country station wagons had all been dropped the previous year. The 1978 Newport offered the American car industry's last true two-door and four-door hardtops.
