The Dodge St. Regis is an automobile that was marketed by Dodge from the 1979 to 1981 model years. Replacing the Monaco, the St. Regis was the largest Dodge sedan, positioned above the mid-size Diplomat and Aspen. In contrast to both the Monaco and the Diplomat, the St. Regis was offered solely as a four-door sedan. Produced for a single generation, the St. Regis is one of the shortest-lived Dodge nameplates. Deriving its name from a 1950s Chrysler trim package, the St. Regis was the first example of downsizing of the full-size Dodge sedan line. For 1982, the model line was discontinued, with the Dodge Diplomat serving as the largest Dodge; the next full-size Dodge sedan was the 1990 Dodge Monaco (derived from the Eagle Premier, itself a version of the Renault 25). Dodge would not market a rear-wheel drive sedan until the 2006 Dodge Charger. The Dodge St. Regis was assembled alongside the Chrysler Newport, Chrysler New Yorker, and Plymouth Gran Fury by Chrysler at Lynch Road Assembly (Detroit, Michigan), becoming the final production vehicles produced at the facility. In total, 64,502 examples were produced. Design overview The Dodge St. Regis was based on the rear wheel drive Chrysler R-body platform. As Chrysler needed to expedite a downsized replacement for the 1974-1977 C-body to market (in response to the 1973 oil crisis), the R-body was developed from existing underpinnings at minimal costs. In place of redesigning the full-size C-body, Chrysler developed the R-body as an update of the intermediate B-body (last released in 1971, dating to 1962). Used by a wide variety of Chrysler model lines, the B-body architecture underpinned model lines ranging from the Dodge Coronet and Plymouth Belvedere to the Dodge Charger and Chrysler Cordoba. Compared to its 1977 Dodge Royal Monaco predecessor, the Dodge St. Regis shed 5.5 inches in length, 2.7 inches in width, 3 inches in wheelbase, and nearly 900 pounds of curb weight (dependent on powertrain). The 225 Slant-6 inline-6 was now the standard engine with optional 318 and 360 V8s; a three-speed automatic was paired to all three engines. In deference to fuel economy standards, the 400 and 440 big-block V8s were deleted from the engine lineup. The front suspension continued to offer Chryslers signature longitudinal front torsion bars, called Torsion-Aire, and anti-sway bar with a solid rear differential connected to leaf springs. The "St. Regis" name first saw use as an
