Antoine de la Mothe Cadillac
Upon his arrival in America, La Mothe adopted his title after the town of Cadillac, Gironde in southwestern France. The city of Detroit became the world center of automobile production in the 20th century. William H. Murphy and Henry M. Leland founded the Cadillac auto company and paid homage to him by using his name for their company and his armorial bearings as its logo in 1902. Various places bear his name in America, in particular Cadillac Mountain in Maine and the town of Cadillac, Michigan.
Cadillac Eldorado
Cadillac introduced the eighth generation Eldorado in 1979, largely as a rebadged variant of the Buick Riviera and Oldsmobile Toronado. Smaller, more fuel efficient 350 and 368 in³ (5.7 and 6.0 L) V8s replaced the 500 and 425 in³ (8.2 and 7.0 L) engines. A diesel 350 was available as an option.
In 1980, the gas 350 was replaced with the 368 except in California, where the Oldsmobile 350 was used. In both the 1980 Seville and Eldorado (which shared frames) the 368s came with DEFI (later known as throttle body injection when it was later used with other GM corporate engines), whereas in the larger RWD Cadillacs it came only with a 4-barrel Quadrajet carburetor. Independent rear suspension was adopted, helping retain rear-seat and trunk room in the smaller body. The most notable styling touch was an extreme notchback roofline. The Eldorado "Biarritz" model used a stainless-steel roof concept similar to the first Brougham. The Eldorado featured frameless door glass, and the rear quarter windows re-appeared as they did before 1971, without a thick "B" pillar. The cars were not true hardtops, as the rear quarter windows were fixed. Sales set a new record at 67,436.
