LaSalle
Cadillac's companion marque of 1927–1940, combining a lower-priced luxury range with influential styling and successive V8 and straight-eight engines.
Historical overview
LaSalle was an American General Motors marque built under Cadillac from 1927 to 1940. It offered a less expensive route into Cadillac-associated luxury while retaining its own name and identity. The expression Cadillac LaSalle reflects that manufacturing and sales relationship: LaSalle was a companion make, with its own series and body styles, rather than a Cadillac trim or a single model generation.
Its importance extends beyond its relatively short life. The original LaSalle brought Harley Earl’s approach to styling into GM’s production-car programme. Later cars demonstrate how the division adapted its companion range through changes in engines, bodies and market position. The final 1940 cars were followed in their price position by the Cadillac Series 61 for 1941. The Henry Ford documents the original car’s development; Mac’s Motor City Garage describes the marque’s discontinuation.
Origins and the Cadillac relationship
In 1926, GM president Alfred P. Sloan sought a lower-priced companion for Cadillac. Harley Earl, whose background was in custom-car design, shaped the resulting 1927 LaSalle. The Henry Ford identifies Cadillac’s Motor Car Division as the manufacturer and Detroit, Michigan, as the place of manufacture of its surviving 1927 roadster. That car has a 303-cubic-inch V8 and a three-speed manual transmission; these identify the early car rather than the entire LaSalle range. Museum vehicle record.
Cadillac’s advertising explicitly introduced LaSalle to its existing audience. A 1927 advertisement preserved by The Henry Ford presents it as a new car for Cadillac households. The museum connects the car’s success with GM’s creation of the Art and Colour Section under Earl, establishing styling as an organised corporate activity. LaSalle’s historical significance is therefore more precise than a sweeping claim that it was the first attractive or deliberately designed automobile. Period advertisement and museum interpretation.
The original cars and coachwork
The 1927–1928 range was identified as Series 303. It encompassed several bodies, including sedans, coupés and open cars. Fisher and Fleetwood coachwork appeared in the catalogue, and body availability and wheelbase depended on the particular version. A roadster photograph should consequently not be read as representative of every LaSalle’s seating, roof or chassis length.
The early catalogue also illustrates a recurring identification problem: the same broad body description can occur with different style numbers in successive years. The Cadillac Database distinguishes the 1927 Victoria coupé from its 1928 counterpart and records separate Fisher and Fleetwood offerings. Body-builder and style-number evidence are more useful for identifying an individual car than the general phrase “Cadillac LaSalle”. 1927–1928 catalogue history.
The straight-eight years, 1934–1936
For 1934 LaSalle adopted an L-head straight-eight, replacing the V8 layout of the original range. The Cadillac Database identifies the 1934 car as Series 350, with a 240.3-cubic-inch engine, and lists Fleetwood sedan, coupé and convertible coachwork. Its narrow radiator treatment and more streamlined front ensemble gave this phase a recognisable appearance. 1934 specifications and body catalogue.
The 1935 and 1936 cars continued the straight-eight phase. By 1936, the catalogue designation was Series 36-50, and the Oldsmobile-derived engine displaced 248 cubic inches. Fisher bodies included a fixed-roof coupé, two- and four-door sedans and a convertible coupé. The specification included independent “Knee-Action” front suspension, hydraulic brakes and Fisher’s steel “Turret Top” roof construction on closed bodies. These were developments within LaSalle’s history, not equipment that can be assigned retrospectively to a 1927 car. 1935 record; 1936 record.
V8 power returns for 1937
The 1937 model-year Series 37-50 returned to Cadillac V8 power with a 322-cubic-inch L-head engine. Its Fisher-bodied range included coupés, sedans and convertibles, while a separate longer commercial chassis was also offered. The chassis specification included an X-member frame, independent front suspension, hydraulic brakes and a hypoid rear axle. None of those details makes a commercial chassis equivalent to a regular passenger sedan.
The 1937 cars appeared during late calendar 1936; the surviving price-list information is dated October 1936. “1937” therefore identifies their model year, not a guarantee that every example was manufactured during calendar 1937. The upright grille, altered hood detailing and lower headlamp position also help distinguish this revision from earlier straight-eight cars. 1937 specifications and contemporary price-list notes.
The final 1940 range
LaSalle’s last model year offered the Series 50 and Series 52 Special. The Special’s lower, more flowing body treatment differentiated it from the regular series. Closed coupés and sedans were accompanied by convertible offerings. Headlamps integrated into the front fenders, a narrow central grille and a column-mounted gear lever characterised the final cars. The 322-cubic-inch L-head V8 remained, with a quoted 130 brake horsepower for 1940; the 1937 record’s 125 bhp should not be substituted for it. 1940 specifications and body catalogue.
The 1940 models were introduced in October 1939. Although proposals existed for a subsequent LaSalle, GM ended the production marque in 1940 and used the Cadillac Series 61 to occupy its former market position for 1941. This was a change in GM’s product strategy, rather than a wartime production pause followed by a post-war LaSalle revival. Final-year history.
Production, exports and identification
LaSalle’s manufacturing origins lie in Cadillac’s Detroit operation. Its model-year catalogues describe a changing range of passenger bodies and, in later years, commercial chassis. Export activity also needs to be distinguished from domestic finished-car production: the 1940 Cadillac Database record separately identifies exported chassis and Series 52 sedans shipped in completely knocked-down form. That evidence establishes export supply, but does not by itself identify every destination, overseas assembly plant or local equipment specification. 1940 production and body entries.
For an individual LaSalle, establish the series, model year, body style and engine before assigning specifications. A series number is a catalogue designation; a coupé or sedan is a body style; a straight-eight or V8 describes engine architecture. Annual styling revisions do not automatically define separate generations. First-registration dates likewise should not replace model-year or build-date evidence.
Production totals and some dimensions differ between the compiled references, including conflicting figures within the early and final-year records. No reconciled marque-wide total or universal wheelbase is asserted here. The GM Heritage Archive maintains separate LaSalle information kits by year under Cadillac, providing a route to the period documentation needed for more detailed vehicle identification.
Legacy
LaSalle joined Cadillac manufacture to a distinct companion identity and helped establish styling’s institutional role within General Motors. Its engine changes show why the name cannot be reduced to one mechanical specification, while its replacement in the price hierarchy by a Cadillac-badged car marks the end of the companion-marque experiment. The cars remain a separate historical lineage within Cadillac’s wider story. The Henry Ford’s design history; LaSalle’s final year.
