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.

In 1985, the Somerset was introduced as its own model. Also, the Electra coupe and sedan were redesigned and converted to front-wheel drive and were initially powered by a carbureted 3.0 liter Buick V6 engine, a fuel injected 3.8 liter Buick V6 engine, or a 4.3 liter Oldsmobile diesel V6 engine. Each was mated to a 4-speed automatic transmission with a 0.70:1 overdrive gear. The 3.0 liter V6 and 4.3 liter diesel V6 were no longer offered after 1985. During the 1985 to 1989 model years, the Electra name also continued to be used on the rear-wheel drive B-body "Estate" station wagon. Buick-powered cars won pole and second position in qualifying for Indianapolis 500. Over the next few years, Buick engines would set a number of stock-block records and twice would power a third or more of the 33-car Indy 500 field (11 in 1990 and 12 in 1992). 1985 would be the final year for the rear-drive LeSabre before another downsizing and conversion to front-wheel-drive for 1986 (sedans and coupes only; the rear-drive LeSabre Estate Wagon would soldier on largely unchanged a few more years). The top-line LeSabre Limited became the LeSabre Limited Collectors Edition to mark the end of an era for the rear-wheel drive coupe and sedan; engine offerings included the standard 231 V6 (sedans and coupes) or optional Olds 307 V8 or Oldsmobile 350 diesel V8. 1985 saw Buick's best model year sales to date with 915,336 vehicles sold.
