The LaSalle was an automobile product of General Motors Corporation and sold as a companion marque of Cadillac from 1927 to 1940. The two were linked by similarly themed names, both being named for French explorers — Antoine Laumet de La Mothe, sieur de Cadillac and René-Robert Cavelier, Sieur de La Salle, respectively. Built by Cadillac to its high standards, the LaSalle soon emerged as a trend-setting automobile. Earl was then placed in charge of overseeing the design of all of General Motors' vehicles.
The LaSalle was offered in a full-range of body styles, including Fisher and Fleetwood Metal Body-built custom designs. The roadster could also be ordered in two-tone color combinations, at a time when dark colors like black and navy blue were still the most familiar colors produced by manufacturers. Earl's design even included a nod to the inspirational Hispano-Suiza, with the marque's circled trademark "LaS" cast into the horizontal tie bar between the front lights.
Wheelbases ranged between 128 in (3,251 mm) and 134 in (3,404 mm). The LaSalles of this era were equipped with Cadillac's "Ninety Degree V-8", making the car fast, while its smaller size made it sportier and more agile.
