Buick
In 1984, Buick was the official car of the XXIII Olympiad. A reorganization split manufacturing & engineering from sales and marketing. The first pilot Buick is produced at "Buick City", a state-of-the art assembly center built inside the walls of Buick's home plant at Flint. Buick had its best model year sales to date with 906,626 vehicles sold plus Buick worldwide sales topped one million for the first time. To close out 1984, Lloyd Reuss ended his tenure as general manager of the Buick Motor Division.
Buick LeSabre
In addition to being Buick's entry level vehicle, the LeSabre was consistently Buick's best selling full-size car. Of the four nameplates introduced in 1959 (LeSabre, Invicta, Electra, Electra 225), the LeSabre nameplate lasted the longest.
From 1959 to 1961, the LeSabre was powered by a 364 cubic-inch V8, which was smaller than the 401 cubic-inch V8 used in the more expensive Invicta and Electra models. The 364, which was previously used in all Buicks in 1957 and 1958, was rated at in standard form with an "economy" version offered as a "no cost" option in 1960-61 and an optional power-pack version with four-barrel carburetor and dual exhausts that was rated at . For 1962-63, the LeSabre came standard with a two-barrel carbureted version of the 401 V8 rated at , or a no-cost "economy" low-compression version rated at . Starting in 1964, all LeSabre models except the Estate Wagon shared their drivetrains with the midsize Buick models by switching to those models' smaller-displacement V8s at least as standard equipment for the next few years with cubic-inch displacements of 300 (1964–65), 340 (1966–67) and 350 (1968–76). A large-displacement would not reappear in a LeSabre until 1970 when a 455 cubic-inch V8 was introduced as an option and was offered through 1976. Beginning with the downsized 1977 models and continuing through three subsequent generations of front-drive LeSabres introduced in 1986, 1992 and 2000, Buick's 3.8-liter (231 cubic-inch)V6 would become the standard engine for most LeSabre models and V8 engines were dropped (except in station wagons) after the last of the rear-drive LeSabre sedans and coupes came off the line in 1985.
